- Q: The matching ratio of masonrying refractory bricks cement
- When building refractory bricks, use matching chamotte, do not use cement
- Q: What material is sk-34 on the refractory brick
- Electric power; refractory bricks, castable refractory, building materials, chemical, glass, ferrous metals and other industries required refractory and insulation materials, all kinds of thermal insulation cotton products, thermal insulation brick, aluminous refractory cement, perlite and other unshaped refractory materials have been the best-selling products
- Q: What are the release agents of refractory bricks?
- Alkalinity, the production process of alkaline, acid and alkali resistant transparent instant thickening powder, you can adjust the proportion according to the cost and needs of quality, environmental protection: One: Add the preservative into water to mix, after soaking one hour, then mixing evenly the production ratio, and then add the super core release agent into water to mix, add flavor pigment masterbatch into water to mix with water mixing, ensure completely dissolved, then add the waste oil, falvor is appropriate amount= release agent. Two, the newest recipe of release agent super core release agent masterbatch, waste engine oil, water, instant acidproof and alkaliproof transparent thickening powder, wire drawing powder, preservative, flavor and pigment= release agent super core wire drawing powder with water mixing, it is the most newly developed special core masterbatch and engine oil of Chengdu Hengfeng Hongye detergent factory, and it doesn't contain toxic solvents, especially 1, it has the following features, after thickening more than half an hour or so, mix evenly is ok, in a few seconds will waste oil and alkali: 10% of waste engine oil, 20% of release agent core masterbatch, 88% of water, 500g instant acidproof alkaliproof transparent thickening powder, 80g wire drawing powder, 1g pigment and preservative and lubricating oil and industrial grease, these integrate with water.
- Q: What is the coefficient of heat transfer for clay bricks?
- The coefficient of heat transfer is called the total heat transfer coefficient. The current standards and specifications of the state are uniformly named as heat transfer coefficients. The heat transfer coefficient K value refers to the stable heat transfer condition, both sides of retaining structure air temperature is 1 degrees (K, c), 1s in the area of 1 square meters of the heat transfer unit, is w / (M2 - degree (W/) m - K, where K can replace c).
- Q: How to calculate the pressure of hydraulic machine pressures refractory brick?
- If it is a plunger type cylinder, the pressure of a cylinder is the cross-sectional area of the piston multiplied by the pressure of the hydraulic system; if it is piston cylinder, that is the inner diameter of the hydraulic cylinder multiplied by the pressure of the hydraulic system. Adopt cm as diameter's unit, a unit of pressure is kilogram force per square centimeter, the calculated result is kilogram which divided by one thousand is ton.
- Q: Whether the fire bricks are needed to be poured before construction?
- Refractory bricks do not absorb water, do not need to water, what's more, refractory bricks need special refractory mortar to build. Refractory brick is used in the high temperature furnace, you won't use it to build walls.
- Q: What is the advantage of the ceramic fiber material compared with the refractory brick?
- Ceramic fiber material is heavier than refractory bricks, property of machinery operation, low heat capacity, and has high anti-stretchability and good thermal shock resistance, low thermal conductivity make its thermal insulation effect is ten times than refractory brick, it won't has crack in sudden coolness and heat, and the construction is much easier than that of refractory brick, not delaying the production.
- Q: What are the sizes and sizes of clay bricks?
- According to the compressive strength (Newton / square millimeter, N/mm2) the size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these 6 intensity levels.The bigger the size, the stronger the compressive strength.
- Q: The shape and size of general used refractory brick
- 240mm * 115mm * 53mm. and the width is 115mm, the shape and size of mechanism red brick is: 230mm * 114mm * 65mm, the outline dimension of special refractory brick is of 65mm thickness according to the national standard: Length is 230mm. That is: Length is 240mm. General type refractory brick's outline dimension is of 114mm width. That is, thickness is 53mm: 345*328*97
- Q: Can refractory bricks be used to build a house?
- Refractory brick can be used to build houses, but you can not use ordinary cement to build, the cost is 3 times than that of ordinary brick.
