Thaum lub sijhawm ua haujlwm ntawm fiberglass yog qhov qub, qhov xwm txheej twg yuav tshwm sim yog tias tus neeg sawv cev sizing tsis ruaj khov?
(1) Hlau kos duab tsis du, thiabfiberglassfilaments yooj yim tawg thiab ya ntawm lub oiler lossis bunching log (phaj), ua rau cov hlau kos duab ua haujlwm tsis ua haujlwm ib txwm. Lub viscosity ntawm tus neeg sawv cev sizing yog siab dhau los yog muaj granular nag lossis daus hauv cov sizing tus neeg sawv cev, ua rau lub zog ntawm cov khoom siv.fiberglassfilaments hloov pauv thiab yooj yim tawg; tus neeg sawv cev sizing yog tsis ruaj khov nyob rau hauv siab shear quab yuam ua hauj lwm, thiab hais precipitate thiab adheres rau graphite roller, ua rau ya.
(2) Ntawm graphite roller ntawm monofilament oiler, lub impregnant muaj ntses qhov muag thiab ntau qhov chaw dub. Qhov no yog vim qee cov khoom hauv cov impregnant muaj cov dej tsis zoo, yog oily, thiab tsis yooj yim rau kev ua raws li cov graphite roller. Nws kuj tseem qhia tau hais tias cov emulsion tsis ruaj khov txaus, thiab qee cov organic film-forming agents tau tso tawm los ntawm emulsion, ua rau cov txheej tsis sib xws ntawm cov fiber ntau thiab txo kev ua haujlwm.
(3) Ua npuas ncauj, uas yog, ua npuas ncauj nyob rau hauv tus neeg sawv cev sizing muaj cua ntau, ua rau foaming ntawm lub monofilament oiler, tsis sib xws txheej ntawm lubfiberglassnto, thiab overflow ntawm sizing tus neeg sawv cev ua npuas ncauj nyob rau hauv lub cia tank thiab ncig tank. Yog vim li cas yog hom tsis tsim nyog thiab ntau npaum li cas ntawm emulsifier, thiab tus neeg saib xyuas tsim nyog yuav tsum raug xaiv rau defoaming.
