Description
Technical field
The present invention relates to building material field, one of specifically a kind of base material that is used to produce building kitchen, washroom exhaust gas flue glass magnesium plate.
Background technology
On September 15th, 2010; " about strengthening the notice of building exhaust gas flue management " (logical [2010] No. 411 of the Guizhou Province section of building) issued in the Guizhou Province's house and the town and country construction Room; There are serious quality problems in the building kitchen of part project in construction use, washroom smoke evacuation, exhaust duct (hereinafter to be referred as exhaust gas flue) according to the document; The exhaust gas flue that part gets into the job site is a defective work, exists in addition to march into the arena that properties of product examining report index is complete, the production assurance system is unsound and construct problem such as lack of standardization.Get into the job site for stopping building material product inferior; Guarantee engineering construction quality; Safeguard the construction market order; Province firmly builds the guiding way that the Room has proposed to strengthen the management of building exhaust gas flue, comprising " before the product entering job site, the original paper of performance of ventilating test report, fire resistance pattern survey report and the vertical bearing capacity of reply exhaust gas flue, the report of anti-soft impulse Performance Detection carries out the strictness examination.Wherein the fire endurance performance should meet " housing construction standard " requirement (GB50368), is not less than 1.00h.Do not reach the national standard code requirement or detect the incomplete product of index and must not get into the job site use." meanwhile, glass fibre and magnesium cement board (hereinafter to be referred as glass magnesium plate) is because the physicochemical property of its excellent fire resistance and high-strength light thereof, and promptly become the focus that industry is paid close attention to.
On May 10th, 2011; Province firmly builds the Room and has issued " about strengthening the additional notice of building flue gas exhaust pipeline relevant issues " (logical (2011) No. 188 of the Guizhou Province section of building) again; File has proposed to strengthen the concrete way of building exhaust gas flue management: " two, completely forbid workshop-based manual production exhaust gas flue; be meant to ban use of the prefabricated exhaust gas flue product of artificial cement mortar; its substitute technology is mainly and adopts high-strength light fire-proof board processing assembling exhaust gas flue, and wherein high-strength light fire-proof board (glass magnesium plate, calcium silicate board with microporous etc.) is necessary for machining, bans use of manual work to paste sheet material.Four, the exhaust gas flue that adopts the high-strength light fire-proof board to make (JC/T194-2006) is carried out according to " house kitchen washroom exhaust duct "." so far, glass magnesium plate directly becomes the only choosing of producing the exhaust gas flue product again because of the mechanized production technology of its energy-conserving and environment-protective, and come by rapid popularization of industry and relevant departments.
Yet in the glass magnesium plate exhaust gas flue that has come into operation, there are quality problems such as damp suction surface halide accumulation (perspiration phenomenon), buckling deformation, goods cracking in most of product.Reason is that most of manufacturer is all more unilateral to the understanding of glass magnesium plate, generally all disposes the technological guidance personnel and the lab assistant of specialty, so the proportion scale of lack of scientific and production technology, has finally caused the quality problems of product.
Summary of the invention
The object of the present invention is to provide a kind of glass magnesium plate that is used to produce kitchen guarding's exhaust gas flue series of products; Its prescription has not only solved the ubiquitous quality problems of glass magnesium plate exhaust gas flue product; Fundamentally improve the using property data of glass magnesium plate exhaust gas flue product especially, prolonged its application life.
Formation of the present invention: a kind of glass magnesium plate that is used to produce kitchen guarding's exhaust gas flue series of products; Its two sides, outside is a nonwoven layer; The centre is a pulp layer, also is provided with the glass layer of cloth between nonwoven layer and the pulp layer, it is characterized in that: the batching formulation ratio by mass parts of said pulp layer is following:
