Q: what's the application of fireproofing abs materials?: fireproofing abs material is quite good, its fireproofing ability is quite good, now it's sales in the market is very well, you can purchase as you want.

Q: Preparation of refractory clay: Is it to make refractories? Add some andalusite to the refractory mortar will improve the effect.

Q: How to hang the suspended brick in the refractory masonry?: First you can weld the metal fastener of the suspended brick and then hang up the brick.

Q: How to do environmental impact assessment for refractory Co., Ltd.: 1, first of all, the EIA unit and the construction party signed the EIA contract. The contract is only legally valid. Generally speaking, the contract will indicate that the first payment has been received before the work begins.2. Collecting information. This is a very important link in the EIA, which is directly related to the quality of the eia. There is a great variety of data,Generally, the construction party will write a list of environmental impact assessment information.

Q: What are the construction measures of refractory material in winter? Please descriptive briefly.: Binding agent should be attaced great importance to when construction is conducted in winter. Generally if the bingding agent is water or cement, antifreezing measures should be taken.

Q: Is the linear change on reheating the same as heating permanent linear change of refractory material?: “+”represents expansion. the afterexpansion and aftercontraction after cooled to be at room temperature. The change may significantly damage the masonry of thermal kiln. There are regulations on the linear change on reheating of common refractory material in the national standard. Some physical chemical changes may continue. It is defined as the change from being heated to the specified temperature of refractory material sample. Heat preserving for a while till afte cooling to be at room temperature, then the residual will expand or contract in its length, heat preservation for a while, organization vitrification, the irreversible changes of its length refers to heating the firing refractory to be at high temperature, so as to make the volume of refractory materials expand or contract, due to the influence of uneven temperature or lack of time, otherwise it will cause the deformation of the refractory ball and make this indicator within standard even reach smaller value, so firing control must be strengthened in product production. But it is should not be too high. For refractory materials with same chemical composition, the linear change on reheating is produced in the heating process. Properly increasing sintering temperature and prolonging the holding time is an effective process measures, make its firing inadequate. When subjected to high temperature, it can reduce the thermal shock resistance. Minus sign "-" represents contraction. The permanent line rate refers to heating the fire refractory ball to the specified temperature. Linear change on reheating, also known as residual linear change, is an important indicator to assess the quality of refractory in the long time use. To control the permanent line rate within the standard or reach the minimum value.

Q: What is the type of heat resistance property of high temperature electric furnace ?: According to the levels of refractoriness : Common refractories: & Gt: 1580 ℃ ~ 1770 ℃ advanced refractories: 1770 ℃ ~ 2000 ℃ AAA refractories; 2000 ℃

Q: What is refractory aggregate?: Refractory aggregate is fire-resistant product improved with low temperature binder, chemical?compound and normal temperature strength.

Q: How many grades of fire?rating are there for interior decoration materials?: It can be divided into structural material and base?material based on materials. It can also be divided into flammable, flame retardant and non-combustible materials based on fireproof types. There is no fire?rating for materials. But lengths of time of flammability limits are different.
