PVC cov khoom siv dav siv hauv lub neej niaj hnub, tab sis lawv kuj yuav muaj qee qhov teeb meem thaum siv.Niaj hnub no, manufacturers ntawmSainuo polyethylene waxyuav coj koj mus kawm txog cov teeb meem whitening ntawm cov khoom PVC.

Thaum cov khoom siv PVC raug tshav kub rau sab nraum zoov, vim muaj qhov cuam tshuam ntawm ya raws, carbon dioxide, sulfur dioxide, thiab lub teeb nyob rau hauv cov huab cua, lawv yuav nthuav tawm qhov tshwm sim whitening, feem ntau yog vim li cas hauv qab no:
1. Whitening tom qab immersion dej
Ntau hom pob tshab PVC cov khoom tuaj yeem pom cov xim daj ntseg dawb thaum sib cuag nrog dej lossis chav dej rau lub sijhawm ntev.Cov khoom muag muag muaj zog dua li cov tawv tawv.Vim yog immersion dej, plasticizers, stabilizers, thiab lwm yam. precipitate los ntawm PVC thiab undergo hydration, tsim hydrated precipitates rau saum npoo ( cuam tshuam rau pob tshab).Txawm hais tias cov dej ntub dej tau ploj mus, plasticizers thiab stabilizers tsis tuaj yeem rov qab mus rau lawv qhov qub.Tsuas yog los ntawm kev nce qhov kub thiab txias tuaj yeem ua kom sib haum ntawm plasticizers thiab stabilizers rov qab ua ntej lawv tuaj yeem ua pob tshab.
2. Ua kom dawb tom qab raug tshav ntuj
PVC cov khoom raug tshav ntuj sab nraum zoov kuj tuaj yeem pom cov xim dawb vim tias muaj kev cuam tshuam ntawm ya raws, carbon dioxide, sulfur dioxide, thiab lub teeb hauv huab cua.Qhov no muaj feem xyuam rau cov compatibility ntawm stabilizers.Nyob rau hauv cov hlau soaps, benzoates nrog zoo compatibility nrog PVC pom tsawg whitening tshaj stearates.Organic tin tsis yooj yim rau whiten, thiab sulfur-muaj cov organic tin yog qhov zoo tshaj plaws, ua raws li lauric acid ntsev thiab cov ntsev ntsev.Ntxiv lub teeb stabilizers, phosphite esters, kua sib xyaw stabilizers, thiab lwm yam tuaj yeem tiv thaiv lossis txo qhov tshwm sim ntawm cov xim dawb ntawm PVC los ntawm raug tshav ntuj.

Cov khoom siv PVC tawv yuav tig dawb tom qab raug nyob hauv Florida lossis lwm qhov chaw ntub dej, tab sis yuav tsis nyob dawb thaum raug hauv Arizona.Yog li, cov av noo yog ib qho mob uas txhawb nqa cov xim dawb ntawm PVC los ntawm kev raug tshav ntuj.
3. Kev nyuaj siab dawb
Stress whitening yog hais txog qhov tshwm sim ntawm kev ua kom dawb huv hauv cheeb tsam ntawm PVC cov khoom, xws li khoov, creases, thiab stretching cheeb tsam, nyob rau hauv qhov kev txiav txim ntawm mechanical sab nraud quab yuam.
Qhov no tej zaum yuav yog vim qhov kev hloov ntawm cov qauv molecular tshwm sim los ntawm kev quab yuam sab nraud, kev taw qhia ntawm cov saw hlau molecular, kev hloov ntawm PVC ntom, thiab cov tsos ntawm voids ntawm qee cov molecules los tsim lub teeb tawg, uas ua rau cov khoom siv PVC tshwm dawb.

4. Lwm yam tshuaj dawb
Thaum lub sijhawm ua cov khoom lag luam PVC pob tshab, yog tias siv cov roj nplaum ntau dhau, cov roj nplua nyeem ntau dua tuaj yeem ua rau cov khoom pob tshab los ua cov khoom dawb, uas qee zaum hu ua whitening.
Qhov no whitening tshwm sim feem ntau ua rau pom tseeb siv quav ciab zoo li tshuaj nyob rau saum npoo ntawm cov khoom.Txoj kev daws teeb meem yog txo cov roj nplua nyeem siv los yog hloov mus rau lub roj nplua nyeem nrog kev sib raug zoo dua, kom ua tiav qhov sib npaug ntawm cov roj lubrication sab hauv thiab sab nraud ntawm cov mis.
