Description of Refractory JM Mullite Insulation Brick
Lightweight mullite kiln bricks refractory for sale are made from good quality and superpure raw materials, with strictly classified fillings according to their grades. These fillings can form a uniform pore structure after burnt during the process of manufacture. Each grade of products has unique design to meet different thermal, physical and chomical demands.
Application of Refractory JM Mullite Insulation Brick
Mullite insulation furnace bricks refractory material can be used in linings or heat-insulating materials of the industries, such as, ethylene pyrolysis furnaces, tubular furnaces, reforming furnaces of synthetic ammonia, gas generators and high-temperature shullte kilns, etc
Mullite Insulation furnace refractory material can be used as working lining, where contact with flames directly. This kind of brick can save the kiln energy very much

- Q:How does the cement produce! What matter! Why did she get angry?
- The production process of cement, limestone and clay as the main raw material, the broken, ingredients, grinding made of raw materials, feed into the cement kiln calcined mature material, add the appropriate amount of gypsum (sometimes mixed with mixed materials or admixture) Come into being
- Q:I'm doing a project wich required me to calculate the transfer rate of Barite Cement from tanks to tanks. I've run couple of calculation but i'm not sure it is the correct one or not. Please advise.
- Cement is normally a dry powder if the system is a screw the rpm x the screw pitch volume will get you there. If you used a forced eductor use the ACFM x percent of flow /air per cent If you used a vac system and had head and lift and pipe loss and lots of other losses. Just add up all that and get a feasible answer..when you ask get specific... From the E
- Q:Which cement is populer at bangladesh?
- Border jumper brand best quality
- Q:What is the meaning of 53 grade cement ?
- The grade of a portland cement corresponds to how much pressure it can take after it has set for 28 days. 53-grade cement must have a compressive strength of 53 MegaPascals (7687 pounds per square inch) after 28 days. There are also 33 and 43 grades, which must have minimum compressive strengths of 33 and 43 MPa respectively.
- Q:what is the difference between concrete and cement and stuco?
- cement is one of the products used to produce concrete and stucco. Concrete is used for slabs and sometimes walls and floors of buildings. Stucco is used to coat walls as a finish product.
- Q:I really need to have the maximum amount of information between these two main types of cement.Also, please give some examples of non - hydraulic and hydraulic cement.Thank you!
- Non Hydraulic Cement
- Q:i am making a disc golf course tee for my boy scout eagle project. i know a little about cement, but for anyone who knows a lot about cement construction, can you explain this...i need to make a rectangular and circular tee(which is a cement platform where one would stand while throwing a disc). the circle has a diameter of 11ft and rectangle is 11x9. I will be building it on dirt, which is level. I think i will need to dig a hole in the ground in the shape i want. then i have some gravel to put in. then cement in the hole. anyone know how much gravel, or if any, i should put in before i lay in the cement in the hole? thanks people!
- gravel will help prevent the ground underneath your platform from eroding away. 4 inches of gravel should work for you project. If you really want to try and keep the cracking and shifting to a minimum you should dig a could of piers or post holes below the frost line in your area (normally pretty deep) then pour the concrete mix in to add stability.
- Q:what is the Density of Port land cement, and which material is mostly use in cement.?
- The okorder , especially Design and Control of Portland Cement Concrete. The major products after hydration of cement are tri-calcium silicates and di-calcium silicates. The density of un-hydrated cement is about 60 to 75 pounds per cubic foot. The density of hydrated cement is dependent on the water to cement ratio and the degree of hydration as it can change with time. The major ingredient of concrete are the coarse and fine aggregates. The density of normal concrete may vary between 135 to 145 pounds per cubic foot. The density of light weight concrete may vary between 90 to 110 pounds per cubic foot.
- Q:then how much ice will be requiredIf Specific heat of cement is 0.84 Kj/Kg KLatent heat of melting of ice is 334 KJ/Kg K
- Heat lost by cement=heat gained by melting ice Heat= mass X specific heat X change in temp Heat = mass X latent heat of fusion (melting) If the ice is at 0oC, then the 2 equations can be set equal to each other and the mass of ice is the unknown Since specific heat is in Kj/Kg/K, you need to change mass of 1 ton to Kg, and temperatures to K
- Q:does anyone have any experience in that? does it reduce the noise a lot or just a bit? and about the ceiling... my neighbors throw and drag things on the floor (they're mental cases, fruitcakes). i can't afford to move right now because the house is bought so i'd have to sell and buy another house. can't do that right now. and it always costs money.to what extent will the cement on the ceiling reduce the noise?what kind of windows are the best?thank you all...
- I have a best reply for you...I am an excessively mild sleeper, and so they truthfully make instruments that make white Noise. They almost make a whirring sound, very similar to a fan, however the frequency is such that it particularly is helping to dam out external noises as good as sporadic noises, such because the mobilephone ringing or sounds from persons speakme. They additionally promote sound machines that make a style of sounds starting from rain, to babbeling brook to the sound of night time time crickets. To discover the white noise machines simply sort that into the seek bar, many web sites promote them at fair charges. Hope this is helping you out!
