Pib ua haujlwm nrog polymer av nplaum, ua ntej txhua yam, koj yuav tsum kawm kev nyab xeeb cov tswv yim zoo. Yog tias koj ua raws li tag nrho cov lus qhia, siv cov av nplaum polymer nyob hauv tsev yuav tsis muaj kev phom sij.
Yuav tiv thaiv koj tus kheej ntawm cov tshuaj phem npaum li cas
Lub hauv paus ntawm cov yas yog polyvinyl chloride, nyob rau hauv nws tus kheej cov khoom siv no muaj kev nyab xeeb, tab sis yog tias qhov kev pom zoo kom sov los ntawm 110 txog 130 ° C dhau los thaum lub sijhawm ci, cov tshuaj carcinogenic yuav pib tso tawm ntau. Ntawm lawv yog qeeb-ua yeeb yam neurotropic tshuaj lom - vinyl chloride, thiab dhau ntawm nws - gaseous hydrochloric acid, hydrogen chloride.

Koj yuav tsum tau zuaj zoo heev kom txog thaum cov av nplaum ua kom ywj siab thiab khov, thiab cov yas yws yog tusyees faib thoob plaws hauv daim. Koj tuaj yeem tso kom sov sov me ntsis los ntawm kev tso rau hauv lub roj teeb sov. Nws yog ib qho tsim nyog los zuaj cov av nplaum, txawm tias nws zoo nkauj heev thiab pib mos, kom tusyees faib tag nrho cov khoom siv. Txwv tsis pub, cov khoom tiav tiav yuav dhau yooj yim.
Los ntawm kev sib xyaw xim ib qho nrog lwm tus, kev paub tshiab tau txais. Sib tov kom huv si kom txog thaum ua homogeneous kiag li, tshwj tsis yog qhov pib hloov xim meej tau npaj los. Av nplaum feem ntau yuav tsum tau dov mus rau hauv ib txheej nyias nyias, rau qhov no muaj cov tshuab muab tshuaj yooj yim heev, nws kuj yooj yim rau kev ua haujlwm nrog acrylic dov koob. Lub chaw ua haujlwm yuav tsum khaws cia kom huv li sai tau, ib txwm muaj pob khoom ntawm cov ntaub so ntub ntawm txhais tes kom so koj txhais tes thiab ua haujlwm nto tom qab txhua xim tshiab. Cov hnab looj tes roj hmab yuav tuaj hauv tes kom tsis txhob tawm tus ntiv tes thaum thaij duab.
Tej qhov cub me me nrog kev paub txog qhov kub thiab txias kom haum rau kev ci. Ua raws li tuab ntawm cov khoom, cov av nplaum yog ci rau 15-30 feeb. Nws yog qhov yooj yim tshaj plaws los siv daim nplais lossis daim ntawv ci rau ci. Ntau tus neeg kuj siv iav, tab sis nws tuaj yeem tawg.
Tom qab cov khoom lag luam cia txias lawm, koj yuav tsum tau nqa tawm cov khoom tiav zaum kawg. Nws yuav tsum tau ua ntaub ntawv, sanded thiab polished. Koj yuav xav tau cov ntawv nplaum lossis cov ntawv ntsia ntsia. Txhawm rau kom tsis txhob tshem cov plua plav tom qab, nws yog qhov zoo tshaj plaws rau kev ua hauv dej, tom qab uas cov khoom muag dries thiab, yog tias tsim nyog, yog varnished.
