Thoob Ntiaj Teb - Tus PET Zoo Tshaj Plaws: Cov Polymer Zoo Tshaj Plaws rau Kev Siv Ntau Yam
Cov Ntawv Thov Tseem Ceeb
PET siv dav hauv kev lag luam ntim khoom, tshwj xeeb tshaj yog rau cov fwj dej haus. Nws cov khoom zoo heev tiv thaiv cov pa oxygen, dej noo, thiab carbon dioxide ua rau nws yog cov khoom siv zoo tshaj plaws rau kev khaws cia qhov tshiab thiab zoo ntawm cov dej haus carbonated, kua txiv hmab txiv ntoo, thiab dej. Qhov pob tshab ntawm PET ua rau pom tseeb ntawm cov khoom sab hauv, ua rau nws muaj peev xwm ua lag luam tau zoo dua. Tsis tas li ntawd, cov fwj PET yog lub teeb yuag, tsis yooj yim tawg, thiab yooj yim tuav, ua rau lawv yooj yim rau cov neeg siv khoom. Hauv kev ntim khoom noj, PET siv rau cov thawv los khaws ntau yam khoom noj, muab kev tiv thaiv kev puas tsuaj thiab tswj cov saj thiab zoo ntawm cov khoom.
Hauv kev lag luam textile, PET yog cov khoom siv tseem ceeb rau kev tsim cov xov hluavtaws. Cov xov no, hu ua polyester, muaj lub zog zoo heev, tiv taus wrinkle, thiab cov khoom qhuav sai. Lawv siv dav hauv kev tsim khaub ncaws, cov ntaub hauv tsev, thiab cov ntaub lag luam. Cov xov polyester ua los ntawm PET tuaj yeem sib xyaw nrog cov xov ntuj kom txhim kho kev ruaj khov thiab kev ua tau zoo ntawm cov khoom kawg. Tsis tas li ntawd, cov xov tuaj yeem yooj yim zas xim, uas tso cai rau ntau yam xim thiab cov qauv kom ua tau raws li cov kev xav tau sib txawv ntawm kev zam thiab kev tsim qauv.
Kev lag luam hluav taws xob kuj tau txais txiaj ntsig los ntawm cov yam ntxwv tshwj xeeb ntawm PET. Nws yog siv rau hauv kev tsim cov yeeb yaj kiab rwb thaiv tsev thiab cov kab xev vim nws cov khoom rwb thaiv tsev hluav taws xob siab. Cov yeeb yaj kiab PET yog nyias, yoog tau, thiab muaj kev ruaj khov zoo, ua rau lawv tsim nyog rau kev siv hauv ntau yam khoom siv hluav taws xob xws li capacitors, transformers, thiab cov laug cam luam tawm. Tsis tas li ntawd, PET yog siv rau hauv kev tsim cov ntxaij vab tshaus LCD ua cov khoom siv substrate, muab qhov chaw du thiab ruaj khov rau cov khoom tso saib.
PET kuj tseem siv rau hauv kev lag luam tsheb. Nws yog siv los ua cov khoom siv sab hauv, xws li cov qhov rooj vaj huam sib luag thiab cov rooj zaum, vim nws cov khoom zoo nkauj thiab tiv taus kev hnav thiab rhuav. Cov khoom sib xyaw ua los ntawm PET yog siv rau hauv kev tsim cov khoom siv tsheb kom txo qhov hnyav thiab txhim kho kev siv roj. Ntxiv mus, PET yog siv rau hauv kev tsim cov khoom siv cav thiab cov khoom siv roj vim nws tiv taus cua sov thiab tshuaj lom neeg.
