Kev ua cov txheej txheem thiab kev siv ntawm cov menyuam nplaum
Lub hauv paus phaj ntawm cov menyuam nplaum yog polyethylene zaj duab xis, uas yog tsim los ua cov menyuam. Cov nplaum zaj duab xis muaj kab ua ntej txiav. Cov ntug ntawm cov menyuam tau tev tawm kom yooj yim tev. Cov colloid yog polyacrylic acid roj nplaum kom ntseeg tau tias nws tsis degummed. Nws yog qhov yooj yim los siv tus kov; nws txais yuav PE yeeb nkab ntiv nplhaib, uas yog huv thiab ntshiab, Khaws lub nruas tsis ua haujlwm; thiab zam ob yam kev qias neeg tshwm sim los ntawm cov tais diav ib txwm muaj: xws li khaub ncaws, khaub ncaws, khaub ncaws thiab lwm yam khoom lag luam thiab kev ua haujlwm huv.
Cov hmoov av nplaum nplaum siv rau hauv qhov chaw siv: Cov hmoov av nplaum yog tsim rau kev ntxuav qhov chaw ntawm cov laug cam, PCBs, LCDs, teeb qhia, hluav taws xob semiconductors, zaj duab xis raug luam tawm, thiab lwm yam. thiab yuav tsis ua puas qhov chaw ua haujlwm.
