Nyob rau tib lub sijhawm, nws kuj ua tau raws li cov qauv nruj ntawm cov koomhaum xws li FDA, ASTM, thiab NSF hauv Tebchaws Meskas, ua kom muaj kev nyab xeeb rau kev siv.

Nws yuav tsum raug sau tseg tias txawm hais tias PPSU cov ntaub ntawv muaj cov tshuaj tiv thaiv corrosion siab, nws tseem tsim nyog kom tsis txhob muaj kev sib cuag nrog cov khoom kub, acidic lossis alkaline thaum siv los tswj lawv cov khoom zoo. Lub caij no, vim yog tus nqi siab ntawm PPSU cov ntaub ntawv, nws yog ib qho tsim nyog yuav tsum xav txog qhov sib npaug ntawm cov nqi nyiaj txiag thiab kev ua haujlwm thaum siv lawv.

PC (polycarbonate) yog cov khoom siv thermoplastic uas muaj cov khoom siv zoo heev, muaj kev cuam tshuam, tiv thaiv tshav kub, tiv taus txias, nplaim hluav taws, thiab tiv thaiv hluav taws xob ultraviolet.

Cov khoom siv PC muaj lub zog siab thiab muaj zog tiv thaiv, uas tuaj yeem tiv taus sab nraud thiab extrusion. Nyob rau tib lub sijhawm, nws muaj kev kub ntxhov thiab tuaj yeem ua haujlwm ntawm qhov kub thiab txias yam tsis tau yooj yim deformed lossis tawg. Tsis tas li ntawd, cov ntaub ntawv PC kuj muaj qhov txias txias thiab tuaj yeem ua haujlwm ruaj khov ntawm qhov kub thiab txias. Tsis tas li ntawd, cov ntaub ntawv PC kuj muaj cov nplaim hluav taws kub, uas tuaj yeem txo qhov kub ceev thaum muaj hluav taws kub thiab tiv thaiv kom tsis txhob muaj hluav taws kub.

Cov ntaub ntawv PC tau siv dav hauv ntau yam, xws li cov khoom siv hluav taws xob, cov khoom siv hauv tsheb, cov khoom siv kho mob, cov thawv ntim khoom noj, cov khoom siv ua kis las, thiab lwm yam. Nws tuaj yeem siv los ua lub computer casings, xov tooj casings, tsheb teeb, lub raj mis me nyuam, cov tais diav, thiab lwm yam. cov khoom.

Nws yuav tsum raug sau tseg tias txawm hais tias cov ntaub ntawv PC muaj kev ua haujlwm siab thiab ruaj khov, lawv tseem yuav tsum tsis txhob muaj kev sib cuag ntev nrog cov khoom kub, acidic lossis alkaline thaum siv los tswj lawv cov khoom zoo. Lub caij no, vim yog tus nqi siab ntawm cov ntaub ntawv PC, nws yog ib qho tsim nyog yuav tsum xav txog qhov sib npaug ntawm tus nqi nyiaj txiag thiab kev ua haujlwm thaum siv lawv.
