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: what does it mean to RE-CEMENT a boiler and what does it do?: Older Boilers are lined with refractory cement. This is an insulation layer of concrete used to keep a firebox in a boiler from losing valuable heat and it also protects the firebox from metallic overheating which can cause structural failure over time. Your boiler's cement has started to fall apart and the process of Re-Cementing repairs that failure, making the firebox patent and safe again for heating.

Q: The cement industry is an example of an undifferentiated oligopoly. The automobile industry is a differentiated oligopoly.: Well, you basically answered this question on your own. The automobile industry would most likely advertise because their products are differentiated and so advertising would be more beneficial compared to advertising an undifferentiated product.

Q: Any one know the differnt ratios of sand and cement for the different strengths of concrete eg. 25N 35N etc.?: Cement to aggregate ratios do not determine concrete strength. The water to cement ratio is what determines strength. Sand, gravel and other aggregates act as a bonding agent. Normal ratio is 7-15% cement to 14-21% water with remaining percentage as the aggregate.

Q: Why is my lawn dying next to my cement walkway?: Variety of grass you have in your lawn can be of much help to determine the cause of your problem. Cement composition(depending on your cement) will change the pH in your lawn soil, knowing what type of grass you have would be helpful. On the other hand it can be a chinch bug problems(in my case I've Saint Augustine grass and have the same problem) the cement walkway exsert heat and chinch bugs love this. Chinch bugs also effect grasses like aszoysia, Bermuda, and centipede grass. When you said dying, what color was the grass, brown, yellow?. Is it only next to the cement or further into the lawn(center) as well. If the grass is brown next to the cement I treat it with an insecticide for chinch bugs, this will treat the problem. I've used talstar liquid concentrate with the best results(I recommend this product), it also comes in granules for larger areas too. This product is easily found at Wal-Mart, OKorder, etc.

Q: I am thinking about a career in driving a cement truck. Can somebody tell me the upside and downside of this career? I have a class B licenses now so all I need to do is add tanker endorsement to it.: Actually cement trucks don't need cleaning at all. Concrete trucks, on the other hand, are quite messy. Perhaps we should clarify the terminology?

Q: different test on portland cement?: The standard tests for cement are 1) Chemical composition 2) Fineness 3)Compressive strength 4)Tensile strength 5)Consistency 6)Setting times 7)Soundness

Q: i'm replacing my tub area wall with cement backerboard. how do i butt the backerboard end with the textured drywall end? and how can i remove the old drywall joints (the area with the joint tape)? that's where i will butt the concrete backerboard.: use the same nylon joint tape and the thinset that you used on the other joints of the backerboard. aplly the thinset as smooth as possible. when it dry you can apply a layer of drywall joint compound over the thinset. you dont have to over lap the tile over the joint. after the drywall compound dries, sand and finish like the rest of the drywall

Q: What is a chemical that softens rock and cement?: Hydrochloric acid softens cement. You can buy large containers of it for removing cement from brickwork. It will also attack some types of rock, especially limestones. Be careful with it though!

Q: what is the difference between cement and concrete ?: Cement is a bonding agent (lime). Concrete has cement, aggregate (small rocks), and sand. You add water to a concrete mix to cause a chemical reaction that makes it solid.

Q: I have a small very detailed cement dog which got really muddy. I have tried scrubbing it with a brush and warm water, but it still has a brown color that wasn't there before. I am afraid to use anything too harsh for fear of destroying some of the detail wrok.: Get some concrete cleaner. DUH
