1. Dab tsi yog nag lossis daus?
Cov nag lossis daus yog hais txog kev sib sau ntawm cov khoom siv hauv qhov chaw xws li pwm thaum lub sijhawm tsim khoom, uas cuam tshuam rau saum npoo ntawm cov yeeb nkab. Tsis muaj teeb meem dab tsi ntawm kev ruaj ntseg system nyob rau hauv cov txheej txheem extrusion ntawm PVC yeeb nkab, muaj ntau theem ntawm cov teeb meem nag lossis daus.
Raws li peb cov kev soj ntsuam, cov sediment muaj cov roj nplua nyeem thiab sib xyaw nrog me me ntawm cov fillers thiab tsis tshua muaj molecular polymers. Hauv cov txheej txheem tsim khoom, qee zaum yuav muaj qhov tshwm sim pom tseeb los nag, feem ntau tshwm sim nyob rau hauv ob qho xwm txheej: ib qho yog kev sib cais ntawm cov pwm export thiab cov khoom, tsim cov xim dawb los yog daj xim av wax (roj) ntawm lub qhov ncauj pwm, los yog tsub zuj zuj. ntawm ntau thiab ntau whiskers ntawm lub qhov ncauj pwm. Lwm qhov yog qhov pom ntawm cov khoom dawb ntawm cov styling lub tes tsho.
2, kev puas tsuaj los nag
(1) cuam tshuam cov khoom zoo li, geometric loj thiab lub cev ntsuas
(2) Ua kom luv luv ntawm cov pwm tu lub voj voog, txhim kho cov khoom seem, nce nqi ntau lawm
(3) Txhim kho qhov corrosion thiab hnav ntawm cov pwm saum npoo, nce qhov zaus ntawm kev kho pwm, thiab ua kom lub neej ua haujlwm luv
