Four Main Properties of Plastic Refractory  Kiln Refractories Blog
Four Main Properties of Plastic Refractory Kiln Refractories Blog
Plastic Refractory is mainly used as lining materials for various heating furnaces, soaking furnaces, annealing furnaces, sintering furnaces, and electric furnace roofs in the steel industry. The four main Properties of Plastic Refractory are as follows:1, Thermal Shock Resistance Compared with refractory bricks of the same material and other amorphous refractories, the plastics have a low bulk density and a large number of holes and microcracks inside. And when used in the heating process and high temperature, there will be no crystal form change and cause severe deformation. The mineral composition near the heating surface is mullite and cristobalite crystallites, and the glass phase is less. The physical properties of the structure and phase from the side facing the low temperature are tapered rather than violent. Therefore, the plastic refractory has better thermal shock resistance. Therefore, the plastic can be particularly suitable for furnace walls with high temperature fluctuations and high temperature furnace roofs subjected to flame impact or radiation.2, Peeling Resistance The castable has fewer voids than the plastic refractory, even after drying, the aggregate remains in close contact with the cement combination. The cement itself is very dense and fine, so the castable refractory should not be directly impacted by the flame, nor can it withstand the drastic changes in the furnace temperature. Otherwise, due to the sudden expansion of the aggregate, it will unavoidably lead to the collapse of the surrounding cement structure. This phenomenon is known as spalling of the casting lining. In plastic refractory, refractory clay acts as a binder, and the clay shrinks due to drying and dehydration, creating fine gaps around the aggregate. The relatively loose connection has the function of absorbing the sudden expansion of the aggregate. Due to this feature of plastic refractory, plastic refractory linings can be used under the following conditions: (1) direct impact of the flame; (2) high-intensity radiation that burns heat; (3) A drastic change in the temperature of the furnace.3, Corrosion Resistance Refractories used at high temperatures are eroded by various gases and slags and react in various ways, causing changes in material properties and corrosion. The castable with high aluminum cement as the binder has lower acid and alkali corrosion resistance than plastic. Since plastic refractory can be used as a binder for refractory clay, plastics are generally resistant to acids and alkalis.4, Wear Resistance Ordinary plastic refractory, Because the aggregates are bonded together by refractory clay, the strength is not very high, so the wear resistance of the plastics is not very good, and the aggregates are easily detached when rubbed. Due to the compact and compact distribution of the cast lining surface and the exposed aggregate, the high alumina cement binder is protected from the impact of the dust by the aggregate to maintain its bonding force. The wear resistance of castables is usually significantly better than that of plastics. However, phosphate-bonded plastic refractory, whose fine particles maintain high bonding strength, can be used in friction linings under high temperature conditions. Since phosphate is a thermosetting binder, phosphate-bonded plastics require high strength after drying and baking after application.Get More details about the Properties of Plastic Refractory, Please Contact RS Plastic Refractory Supplier, We will give you back as soon as possible!Originally published at on November 6, 2019
Would a Better Video Card Be Worth the Money If I Only Play World of Warcraft on My Computer?
Would a Better Video Card Be Worth the Money If I Only Play World of Warcraft on My Computer?
your processer and ram are good, so yeah, a better video card would up the framerate. the graphics can not get better, but they will look a lot better because of the framerate1. Will A better Video Card With My AMD A64 3400 2.2ghz Make enough of a difference?yes with 7900GS....or 7900GT (200 enough for GT) it will boost up performance of 3D games by 20 % at least..well best of all is you no longer got those lag from Raid or online. its worth it if you play any 3D games2. Which is the better video card (I figure they're probably about the same)? ?they are the exact same just different names3. Which one is better video card?this isnt even a ligitimate comparison-- the 8400 is leeps and bounds past the 6600, were talking at a minimum gsteps. Although it seems you are deciding to go with onboard vid ? since the 8400 is a severely poor representation of the 8000 series of cards. the 8600 is one gstep above the 8500 and below-- so if you have the extra cash (not even that much) then i would at the very least get an 8600 if your going for an 8000 series. otherwise save the cash and get a 7600gtxxx4. Is it more ram i need or a better video card?I would start with an additional 1G of Ram. Your video card looks fine5. Should i get a better video card or increase the ram?Just increase the RAM. Go to "My Computer" and Click on "View System Information". Then Go to the "Advanced" Tab Look for "Performance" and click on settings. Go to the "Advanced" Tab the pops up and then to "Virtual Memory" Adjust the settings to your desire. With 3.2 GHZ You are doing fine. Hope This Helps!!! :)6. Will a better video card help with editing pictures?lol no. it doent help with the actuall editing of the picture. the card u have is standard7. What's a better video card? nvidia geforce gt 540m or intel hd graphics 3000?540m, as it's a dedicated card8. Which is a better Video Card: the NVIDIA Geforce 8400M GS or ATI Radeon X1300?For simple games like the ones you have mentioned the 8400M GS is indeed a whole better. The X1300 is very weak for current games, the 8400M GS is not meant for serious gaming either but out of the two the 8400M GS is better. The 8500 does not exist for laptops so you can compare it. For the record the 8400GM is better than the X1300. By the way you can not build a laptop those graphics cards are for laptops and come built in.9. I need a better Video Card?Better go and check for the system requirements and see if they meet. And another factor, since it's an MMORPG, it might a problem from your internet connection speed? So.. were you on wireless? Were you downloading other files? Was is the server's connection problem? How much speed do you get when downloading, how much did you buy, and is that speed fast enough to connect to the game server? PS: Hey I thought the game is not released yet?! Were you playing the beta or what?? Good luck :)10. Which is a better video card for Gaming.. Intel Family Express Chipset G33/G31 or GeForce6 6600 256MB AGP?The intel chipset is actually ingrained with your motherboard. The AGP card, however, is a separate video card which was meant for the sole purpose of graphics for games. Granted, however, that card is really old - and AGP has been long replaced with PCI-E in the computer world for some years now. But yah that geforce card is a much better choice.11. Whats The Better Video Card?Which Version of each card? This could make a BIG difference12. Which is the better Video Card?without understanding better about your pc this is no longer achieveable to assert what the finest improve course might want to be. A video card and pictures card are in basic terms diverse names for an similar element. Getting one will improve the performance of images on the computer yet no longer person-friendly performance. in case you pc is often very sluggish, then this is totally in all chance you want better RAM. Getting better RAM will likely furnish a larger improve than a pictures card although this is demanding to assert without understanding your contemporary pc specs
Where to Buy Camping Stove Canisters by Oslo Airport in Norway?
Where to Buy Camping Stove Canisters by Oslo Airport in Norway?
I haven't been able to find anything about leftover canisters. However, you could get a new one at the airport. Not at the actual airport, but at a gas station that is directly opposite the airport. I just called them and they sell a gas canister called the Coleman C500. That's the only one they have. But it might fit your stove. If it doesn't fit, then read on.The location nearest to Oslo Airport where I'm sure you can get this is the neighbour town of Jessheim. I have found a number of businesses there that almost certainly sell it. I have also phoned the first one on the list, and they have confirmed that they have gas canisters for a variety of stoves.G-Sport Jessheim 47 63 97 27 37Sport 1 Superstore Jessheim 47 63 97 20 63Jernia Jessheim Storsenter 47 400 05 963These businesses are all within walking distance of each other, so if one doesn't have what you're looking for, you can easily walk to the next one. They all open at 10 and close around 8 or 9 on weekdays.This town is about 10 km from the airport. Will you be renting a car? If so, it's perfectly reasonable to stop by Jessheim and buy everything there. If heading north, though, then it's wiser to stop by Eidsvoll and visit the equivalent shops there.What is your first destination after the airport? The most convenient thing would be to just buy it there. E.G. if you're taking the express train to Oslo Central Station, then just get the canister at a sports store there. If you're going to Lillehammer, then buy it there, etc. Even small towns usually have a sports or hardware store. You might want to call them first (they will almost always speak decent English) to make sure they have what you need.So, if you buy it in a town you'll already be passing through on your journey, you may save yourself a possible detour through Jessheim or Eidsvoll. Although it might exist, I'm not personally aware of any place where you can get second hand canisters. The easiest way may be to buy a new oneI'm traveling to Norway in a few weeks, arriving to Oslo airport. I'm planning on camping in a tent most of the trip and would like to use my gas stove to make tea/food. Since I can't take the gas canister with me on the flight, I have to buy it when I get to Norway. Can you recommend a sports store near the airport where I could buy one?Also, I read somewhere (don't remember where anymore) that people often leave their leftover gas canisters in the airport for other (incoming) travelers to use. Is this true? If so, where can I find these leftover canisters?·OTHER ANSWER:I'm traveling to Norway in a few weeks, arriving to Oslo airport.

Inspired by Ants, the Swiss Research Team Developed a Small Robot
Inspired by Ants, the Swiss Research Team Developed a Small Robot
According to foreign media reports, a research team at the Federal Institute of Technology (EPFL) in Lausanne has developed a small robot inspired by ants. They have good mobility and can communicate with each other, assign roles and complete complex tasks together.Due to the small size of ants, the ability of individuals is very limited. However, under the collective cooperation, a group of ants can work in an orderly way. They can find food, build complex nests, escape predators and so on.EPFL researchers' research published in the journal Nature shows that their newly developed robot has the same ability as ants. These robots are simple in design and weigh only 10 grams, but each robot has a variety of motion modes and can move in a variety of terrain.This kind of robot is named tribots by researchers. It is folded and assembled by multiple thin and light materials. Due to its strange shape, it is also called "three legged robot". And this kind of manufacturing material is completely autonomous and unrestricted. It is also equipped with infrared and proximity sensors for detection and communication. More sensors can also be configured according to the actual application.At the same time, the ingenious combination makes tribots have five different motion forms: vertical jump, horizontal jump, over obstacles, and traveling on platforms and non flat planes."In practical applications, such as emergency search tasks, these robots can act collectively. Moreover, because they have good mobility and communication ability, they can quickly locate targets in large space without relying on GPS or image feedback," the researchers explained"At the same time, because they can be manufactured and deployed in large quantities, even some" casualties "will not affect the success of the task. With its unique collective intelligence, our micro robots can better adapt to the unknown environment. Therefore, in some tasks, they will be better than larger and more powerful robots."
Application Example of ADC Intermittent Conversion Mode Using STM32 Single Chip Microcomputer
Application Example of ADC Intermittent Conversion Mode Using STM32 Single Chip Microcomputer
Sometimes we may need to perform packet conversion on multiple ADC channels, and there is an adjustable time interval between groups. For example, as illustrated below. First convert the first two channels, then the middle two channels, and then the last two channels.If we use the sampling query or interrupt mode, it is also possible to switch and configure the subsequent channels after every two channels are converted, and then start the ad module. As for that time interval, we often use timers to assist. Obviously, this can sometimes seem a little cumbersome.In this case, we can also consider using the discontinuous conversion mode of ADC. That is, an ADC conversion channel sequence is divided into several groups. Each ADC conversion trigger event will convert a group of ad channels, which will be carried out in turn until the conversion of the whole sequence is completed.For example, we use five channels ch1 / CH2 / CH3 / CH4 / CH5 of an ADC module, divide them into three groups, and use a timer to trigger the ADC. In the first trigger, AD conversion of ch1 / CH2 channels is performed, in the second trigger, AD conversion of CH3 / CH4 channels is performed, and in the third trigger, AD conversion of CH5 channel is completed. The fourth trigger performs the same conversion as the first trigger, and the cycle continues.We might as well give a practical example based on the above description. Use stm32f411 discovery development board for debugging verification. Five consecutive ad channels starting from ch1 using ADC1 module are divided into three groups. As shown in the figure below.We use the timer update event to trigger ADC conversion. The interval between group 1 and group 2 conversion and the interval between group 2 and group 3 conversion are controlled by timely adjusting the timing length of the timer.We use the timer update event to trigger DMA, and modify the value of arr by DMA to adjust the time interval between two adjacent groups of transitions. In addition, the conversion result of ADC triggers DMA through EOC event, and DMA orderly moves the conversion result to the specified memory space.After the conversion of the five channels of the whole ADC sequence is completed, the DMA transmission into the ADC is interrupted, and the conversion results of each channel are processed in the interrupt callback function. After that, the next round of ADC conversion can be started.Sort out the whole implementation process mentioned above:1. ADC conversion is triggered by the update event of the timer and performs packet conversion according to the intermittent mode.2. Two DMA transmission channels are enabled, one channel is used for the handling of ADC results, and the other channel is used for the update of timer arr value.When the first timing trigger event occurs, complete the conversion of the first group of ad channels [ch1 and CH2], trigger the DMA transmission of the timer, modify the value of arr, and determine the time interval between the first trigger event and the second trigger event; When the second timing trigger event occurs, complete the conversion of the second group of ad channels [CH3, CH4], trigger the DMA transmission of the timer, and modify the value of arr to determine the time interval between the second trigger event and the third trigger event; When the third trigger event occurs, only the conversion of group 3 ad channel [CH5] is performed here, and the ARR is not modified through DMA. Its value will be specified by the user in the callback function of DMA transmission completion interrupt of ADC.The whole process of configuration and code implementation is posted below for reference. Use the stm32cube MX tool for graphical configuration, and organize the code based on the stm32cube Library of ST company.It is assumed that after the conversion of the first group of ad channels, the conversion of the second group of ad channels is triggered after 0x7000 time units, and then the conversion of the third group of ad channels is triggered after 0x5000 time units. [in practical application, the time base parameters depend on the specific situation]1、 Configuration based on cubemx [RCC / sys configuration omitted].1.1 tim3 configuration, the update event of tim3 triggers ADC conversion and DMA for arr update.1.2 ADC configuration. [select 5 ADC channels, intermittent conversion mode, enable DMA transmission of ADC]2、 Generate initialization code.Based on stm32cube library, the engineering code based on ARM keil MDK integrated development environment is generated.3、 Add user code. [code based on stm32cube library]First, introduce the two arrays used in the user code, namely ADC_ Value [5] and data_ Arr[2].Where ADC_ Value [5] is used to store the conversion result of ADC channel, data_ Arr [2] is used to store arr data to change the timing cycle. They are accessed by different DMA streams.3.1 add the following user code in main().Line 1, clear the timer update event flag.The two lines in the red box respectively start the DMA transmission of ADC / tim3.The fourth step is to execute the DMA request that can update the tim3 event.4. Result validation.Connect the hardware, compile the code, and you can see the conversion results after running. The five ad channels are divided into three groups, and the conversion is triggered successively according to the predetermined time interval, and the conversion result is moved to the specified memory space by DMA. Through the debugger, we can see the ADC results and the corresponding changes of timer arr.Summary: here is mainly to introduce the ADC intermittent conversion mode of STM32 chip, and two peripherals, timer and DMA, are used at the same time. I hope it can bring some reference or enlightenment to readers and be used flexibly in my own development in the future. These peripherals are the most commonly used and basic peripherals of STM32 chip. If we can use them flexibly after mastering them, it will make our STM32 development work more convenient.
