Description
Technical field
The present invention relates to a kind of grid cloth contact polarization detection methods.
Background technology
Fiberglass gridding cloth is mainly used for wall enhancing and other enhancing purposes.Before grid cloth does not have gluing, through weft yarn
For contact without positioning, yarn is easy movement, influences the uniform enhancing effect of grid cloth after cloth veil electric is unsceptered；Later stage is in use, grid
Cloth is soft invisible, and worker's construction usage is very inconvenient；In use, grid cloth is contacted with other objects, thread laying is easy tod produce,
There is broken hole, dossal, influences grid cloth enhancing effect.Grid cloth can after needing coating high molecular material (such as esters of acrylic acid)
For enhancing purposes.
Glass fibre is bonded together by fiberglass gridding cloth by gluing, high molecular material, and by filling yarn packet
It covers, is dried through 130-180 DEG C, high molecular material solidification bonds grid cloth longitude and latitude contact, positions grid contact, junction
It is formed with the solidified film of some strength, certain consolidation strength is provided with through weft yarn contact.Simultaneously one is being formed through weft yarn periphery
Layer protective film, increases grid cloth alkali resistance.After gluing, grid cloth alkaline resistance properties is improved, grid cloth contact is provided with centainly
Consolidation strength, grid cloth sizing, client's construction usage is convenient.Grid cloth contact consolidation effect is commonly called as grid cloth polarization.
The polarization of fiberglass gridding cloth has with rubberized material, glue-spread, drying degree and resting period, environment
It closes.Rubberized material is poor, and solidified film and protective film are poor, and the polarization of grid cloth is poor；Glue-spread is low, and the polarization of grid cloth is low,
Alkali resistance is poor；If the degree of drying is inadequate, internal moisture is not dried thoroughly, after storing a period of time, through weft yarn interface point by inside
Water release influences, and easily causes polarization decline；The good product of degree is even dried, it, also can be by after storing a period of time
Absorbing air moisture in coating material causes polarization to decline.The polarization substantial combined reaction of grid cloth grid cloth it is interior
In quality.Grid cloth polarization is poor, and client will be considered that quality is not good or of poor quality enough, will be complained by client's Batch Claim.
Currently, fiberglass industry is about the standard, specification, patent of grid cloth polarization, not about glass fibers
The detection method of grid cloth polarization is tieed up, this kind of research is also not disclosed to be delivered；Industry personage is generally observed using the method that pulls
Warp thread displacement judges grid cloth positioning performance quality accordingly.This detection mode judges with sense organ completely, without detection data,
It varies with each individual, result difference is larger, and test result is insincere.Because organoleptic detection is also easy to produce quality between manufacturer and downstream client
Dispute.This method is not a kind of method of science.
