Qhov chaw txaus ntshai ntawm cov tshuab txhaj tshuaj molding nyob qhov twg?
Tso lus
Txawm li cas los xij ntawm cov txheej txheem tsim khoom siv, yeej ib txwm muaj qee yam kev phom sij cuam tshuam rau nws. Yas txhaj molding tsis txawv. Qhov phom sij ntawm kev txhaj tshuaj molding yog tiag tiag thiab tuaj yeem cuam tshuam rau qhov zoo ntawm cov khoom thiab cov neeg uas cuam tshuam nrog nws. Txawm li cas los xij, tag nrho cov kev piam sij no tuaj yeem zam tau thiab txo qis, tsuav yog kev saib xyuas kom raug thiab kev paub zoo tau txais ua ntej kev siv cov tshuaj molding hauv kev tsim cov khoom.
PVC teeb meem
Cov kev phom sij tseem ceeb cuam tshuam nrog cov txheej txheem tsim khoom no yog los ntawm kev siv cov yas tsis raug nrog cov khoom tsim, tshuaj lossis lwm yam khoom. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum nco ntsoov nkag siab tias yam khoom twg yog siv rau. PVC yog ib hom yas, tab sis nws tuaj yeem tso tawm hydrogen chloride thaum lub sijhawm tsim khoom. Qhov no tuaj yeem ua rau hnoos, laryngeal spasms thiab lwm yam teeb meem ua pa zoo sib xws.
Hluav taws kub retardant ABS
Muaj cov teeb meem sib txawv uas yuav tshwm sim txog cov pa taws tawm los ntawm kev tsim cov khoom siv no. Feem ntau ntawm cov teeb meem yog txuam nrog qhov muag, qhov ntswg thiab qhov ncauj, ntxiv rau kiv taub hau thiab mob nqaij. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum hnav khaub ncaws tiv thaiv, qhov ncauj qhov ntswg thiab tsom iav kom tsis txhob muaj kev phiv tsis zoo. Feem ntau lwm cov yas siv hauv kev txhaj tshuaj molding tuaj yeem ua rau muaj kev kub ntxhov zoo sib xws. Polypropylene thiab Acetals kuj ua rau khaus rau qhov muag thiab tawv nqaij, ntxiv rau cov mucous membrane thiab ob qho tib si yuav ua rau muaj kev nyuaj siab thiab txawm tias dermatitis thaum raug rau cov khoom.
Lwm yam yas
Tsawg ntom polyethylene yuav ua rau tsaug zog, narcosis thiab asphyxia vim yog cov butane muab tawm thaum lub sijhawm tsim khoom. Qhov no yog tib yam li niaj zaus ntom ntom polystyrene ib yam nkaus.
Tom qab tsim cov yas sib txawv, feem ntau tsis muaj kev phom sij ntau hauv kev txhaj tshuaj molding. Vim li no, feem ntau cov neeg muas zaub uas yuav cov khoom tiav tsis tas yuav txhawj xeeb txog teeb meem kev noj qab haus huv lossis kev mob tshwm sim. Qee cov yas tau tsim los ua cov khoom noj khoom haus qib thaum lwm tus tsis yog, yog li saib rau qhov no thiab hom yas siv rau kev khaws cov khoom tseem ceeb. Feem ntau ntawm cov kev phom sij cuam tshuam nrog kev txhaj tshuaj molding txawm tias zoo dua rau cov pa taws uas tau muab tawm thaum lub sijhawm melting thiab ntau lawm ntau dua li lwm theem. Tias yog vim li cas kev tswj hwm ib puag ncig zoo hauv kev tsim khoom yog qhov tseem ceeb.
