If you’ve kind enquiries, please don’t hesitate to let us know. ^_^

Q:Does anyone know the fire endurance of steel stud partition?: The fire endurance degree is 1 hour. which is in line with the national building material fireproofing test standards. CaSo4.2H2O is molecular gypsum molecular structure formula, containing 20% ??water, crystal water and free water, when putting on fire, 10% of the surface water will slowly evaporate, remaining10% of crystal water. It is a class A fire retardant material itself. The longest time can be 4 hours.

Q:How to hang the suspended brick in the refractory masonry?: First you can fasten the girder and the suspended brick with screws, and then move them to the specified location by a crane. You can contact the refractory plant in Shanshan mountain, Ningxiang Countym, Hunan Province at 0731-7150098.

Q:How to determine the fire resistance rating of the aluminium-plastic?panel?: The fire resistance rating of the aluminium-plastic?panel is determined by two indicators, namely national compulsory standard of GB8624 "Building Materials Combustion Performance Grading Method ", and GB/T17748 "Aluminium-plastic?Composite Panel National Standard" . Classifications of combustion performance of building materials in our country are as follows: A class: Incombustible building materials; B1 class: Flame-retardant building materials; B2 class: combustible building material; B3 class: flammable building materials. The fire resistance rating of the aluminium-plastic composite panel shuld be no less than B1 class. 1. Detection indexes and requirements of fireproof aluminum-plastic composite panel (B1 class): (1) Conduct the test according to GB/T8625-88, the average leftover length of each test specimen should be more than 150mm, (any test piece should have leftover length), and the maximum average flue gas temperature of each test should be no more than 200 ℃; (2) Conduct the test according to GB/T8626-88, flame hight indicators.

Q:Can anyone tell me what material the first rate fire resistant door is?: Material of Class A fire doors mainly are steel, wood, steel and wood, and other materials. Fire door is one of the measures of the building fire separation, usually used on the firewall, entrance and exit of staircase or tube well openings, which is required to hane the abilities of smoke insulation and fire insulation. Fire door plays an important role in prevention of the spread of smoke and fire and the reduction of fire loss. Therefore, we must have strict requirements. Fire doors are divided into class A, class B and class C, whose properties of fire-resistant thermal insulation and fire-resistant integrity should be no less than the following values: Class A should be1.50h; class B should be1.0h; Class C should be 0.5h. - stipulations in article 4.5.1.2 in "The New Standard of Fire Doors" GB12955-2008. I hope my answer can help you. Thank you.

Q:Urgently!! Refractory problems, online, etc.: Uneven contraction. When the magnesia block wall is made, the steel wire mesh can be added to the magnesium block wall. That will solve the problem.

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

Q:What are the new refractories?: Most are ordinary refractories.

Q:How to apply the alumina powder on refractories?: The most common one in use is the refractory bricks.

Q:can slag tailings be used to be the base materials of refractory materials ?: the rest of it can be used as refractory additives. the scale currently used clay bricks to make high-temperature liquid. It is easy to produce large amounts of liquid because of the high iron content, instead of its refractoriness. But it can be used as refractory minaralizer.

Q:What's the requirements of fire-fighting criteria of heat insulating material?: It shouldn't be under than B2 level. Roofing insulation fire rating requirements: the ministry of public security, housing and urban-rural development department issued about printing and distributing the civil building external thermal insulation system and the interim provisions on the exterior wall decorative fireproof prescribed in the notice: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm.
