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 to install cement board for tile floor?: If you have a stiff, as in at least 3/4, subfloor, all you have to do it spread a little thinset on the clean subfloor using a 1/4 X 1/4 notched trowerl and nail it down with roofing nails about 12 on center. Roofing nails because they have a large head and are corrosion resistant and easy to install. Then use some thinset and fiberglass mesh tape to close up the joints between the sheet of tile backer.

Q:What is the total weight of a cubic meter of the mix? what part is cement? stone?sand? add these fractional amounts.what is the result? 420+150+120=690Kg, total 690 -420 used what part =n 420/690divided by 10/10=42/69divided by3/3=14/23 cement, how do you figure out stone and sand?: Cement = 420/690 =14/23 Stone = 150/690 = 5/23 Sand = 120/690 = 4/23

Q:What are the types of portland cement?: There aren't any types. Portland cement is Portland cement.

Q:much does 1 cubic foot of portland cement weight in water?: portland cement has a density of 1506 kg/m? 1 ft? = 0.0283 m? that is dry cement, not setup. You didn't specify if it is dry or setup. mass = 1506 kg/m? x 0.0283 m? = 42.6 kg The displaced water weighs: density of water at 20C = 0.998 g/cm? = 998 kg/m? 998 kg/m? x 0.0283 m? = 28.2 kg subtracting, we get 42.6–28.2 = 14.4 kg, or 31.7 lbs. .

Q:what is its exact chemical composition?: 1. feel slippery- bases are slippery. 2. corrode materials 3. red litmus paper 4. cleaning supplies 5. acidic

Q:Portland cement: Cement Ingredients

Q:Ok well here is the thing. I just got my botom braces the other day and now I have this cement in between my bite to stop me from bitting on my brackets so that bottoms don't come off. I am very aware that I have an over bite. But why did they have to do this. The cement is pilled very high and makes it impossible to chew any kind of food. And I am supposed to wait a month and keep it like this. Has this happened to anybody? If so what did you do? And why does the orthodontist do this? Aren't there other ways to acheive this without using cement in between the teeth. It hurts really bad and feels really weird. I am just not sure what to do. All help is apreciated.: The nickname for this cement on your molars is speed bumps and you're right, it's used to keep you from biting off your lower brackets. Many orthodontists use this when their patients have deep bites. By leaving the bumps on your teeth for a month, the lower teeth can level out quite a bit and really get a lot of correction on the deep bite. Some people adapt to these quite easily, but it sounds like you're having some trouble. Try eating soft foods, like soup, mashed potatoes, etc. since chewing is difficult for you right now.

Q:need specification for this type of cement: Oil well cement can vary depending on the application. Take a look at this link. It has some information on the API specifications that are typically used. You can also get a copy of the specification from API publications.

Q:I am trying to match a cement grout for stone patio to same color as my decomposed granite walkway color. I tried mixing grey cement with decomposed granite as aggregate in various ratios to make the grout (1:2, 1:3) but all are just grey. Would white portland cement (more $$$) work better or still be no match? I am afraid to try the cement color pigments cause I know I will never get it right. The decomposed granite is a light brownish color. They call it quot;orangequot; but that's probably because we are in central Texas and everyone near UT thinks everything is orange. Any help?: The cement color works but a number of small trials are required to get it just correct. The trials need to be made with an adequate size so the components can be measured accurately and reproduced when the sample color is developed. Even after you think you have the correct color, try your proportions once more with a slightly larger sample to verify the correct ratio has been selected. As you are aware the wet color is different than the dried color. I would start with the cheaper cements and only go up in costs if you are not coming up with the color you want. You may want to try using mixtures of different sand colors if the granite is not getting you to the color you want. This definitely is a trial and error project. You may want to go slightly to the darker side of a match in that as the new grout weathers it will lighten slightly. After the grout weathers a very thin mix of cement and pigment can be mixed up and the joints can be painted with the blend. If bad goes to worse you may want to paint all the joints to make them consistent. I have used Liquid Cement Color by Quikrete which I got at Lowes, it was a bear but finally came up with an acceptable match.

Q:My contractor put in a couple of feet of cement board around the lower tub region, but on the upper half of the tub (shower head portion) he put in drywall. He taped the joint where the drywall and cement board meet. A friend who has done some tiling told me that there could be movement on the joints between the cement board and the drywall, which would cause the grout to fail and start to come out. He also didn't like that drywall was used.: That whole area needs to be cement board. There should be NO drywall in the shower area. He took a shortcut to save money. IF you only had a tub that would be fine but with a shower drywall in a NO NO. Make him take out the drywall and install cement board. Even if it was just a tub with no shower he would have had to use green board. Don't let him jack you around with this. It's your bathroom and you want it to last for over 20 years and not just a couple of years. Call your city inspector. Or call the city at 311.
