Description
Technical field
The present invention relates to cement fibrolite plate manufacture technology field more particularly to a kind of production methods of cement fibrolite plate.
Background technique
Cement fibrolite plate is to be equipped with natural reinforcing fiber using siliceous, calcareous material as main material and auxiliary material is modified, warp
Cross slurrying, copy take, pressurize, conserving made of a kind of New Building Materials, cement fibrolite plate application range is very extensive, and thin plate can
For ceiling material, can perforate as sound-absorbing furred ceiling.Conventional plate can be used for wall or ornament materials, and slab can be used as LOFT steel
Structural floor plate, spring layer plate, exterior wall cladding, rinsing plate etc., the length and width standard specification of fiber cement board be 1200*2400mm and
1220*2440mm, individual producers can with length customized in 2000-3000mm, width any specification within 1000-1250mm,
Other specifications can be cut on this basis, the usual thickness of fiber cement board has 6,8,10,12,15,18,20,24,
30mm etc., strong producer can be with any thickness within 2.5-100mm customized, thickness 4mm hereinafter referred to as ultra thin plate, 4-
12mm become conventional plate, 15-30mm and its more than be known as slab, 30mm or more be known as ultra-thick plate.There is no the small of press
Producer can only produce the light water mud plate of 6-12mm；General producer can only produce the conventional plate of 4-12mm, and slab is done well, super thick
Plate can not do；The producer whole nation that thickness 2.5-100mm can be done is few in number.
Cement fibrolite plate can be divided into asbestos fibre cement plate and wood-fibred cement plate by material, and wood-fibred water-powered roller includes wood again
The wood fibre boards such as silk cement plate, wood shavings cement plate, these products have sale on the market, but used wood-fibred is most
The ingredient for the hardening of cement that has an impact can be contained, in the past, hardening of cement is influenced to eliminate, general use grabs compound processing, such as people
Magnesium chloride, calcium chloride or waterglass etc. well known.But the tree species such as the mother-in-law Luo Shuan of the larch, Fei Lvbin production that are produced for Japan,
This processing method still can make hardening of cement insufficient, and intensity requirement is not achieved in wood-fibred cement plate.
In conclusion the present invention propose a kind of production method of cement fibrolite plate improve it is such there are the problem of.
