Description
Technical field
The invention belongs to the heat preserving and insulating material category, specifically relate to a kind of hydrophobic antiseptic aluminum silicate fibre product and working method thereof.
Background technology
Originate from the seventies in last century at China's aluminum silicate fibre product, light because of its unit weight, thermal capacitance is little, thermal conductivity is low, easy construction, be convenient to characteristics such as installation, except that making lining material, well used aspect the adiabatic heat-insulation of high temperature service and pipeline.This fibre product initial stage wet moulding intensity height, but unit weight is big, easily fragmentation, can not reuse the one-time investment height; Adopted dry-press process afterwards; but need add external protection; though two kinds of obtained product application of method are superior than the insulation capacity of other non-like product; but application cost is higher; and the goods of these two kinds of methods productions easy moisture absorption and adherent corrosion ion when normal temperature or high temperature use time-out; cause equipment or pipe surface heavy corrosion; particularly stainless steel equipment and pipeline are even more serious; need to change in advance; shortened the work-ing life of equipment and pipeline; cause waste of material, application cost further improves.
Summary of the invention
The objective of the invention is to overcome above-mentioned not enough problem, provide a kind of unit weight ultralight, not broken, reusable, need not protecting materials, long service life, adiabatic heat insulating effect are good, have hydrophobic, anti-corrosion function aluminum silicate fibre product and working method thereof.
The technical solution used in the present invention is: a kind of hydrophobic antiseptic aluminum silicate fibre product is characterized in that: in the aluminum silicate fiber surface-coated hydrophobic antiseptic wedding agent is arranged;
