Tsis ntev los no, polyvinyl chloride (pvc), cov ntaub ntawv uas ua haujlwm tseem ceeb hauv kev lag luam tshuaj, muaj ib zaug ntxiv ua qhov tsom ntawm kev lag luam. Txoj kev txhim kho hauv nws cov khoom lag luam, kev thov, thiab kev lag luam zoo tau kos ntau kev saib xyuas. Raws li cov ntaub ntawv kev lag luam cuam tshuam, ntawm sab ntau lawm, ua ib qho ntawm cov neeg tsim khoom lag luam loj hauv ntiaj teb no thiab txhim kho lawv cov thev naus laus zis ntawm cov kab ntau lawm. Zhong'an, Jinan, Shandong tshuaj tau tshaj tawm ua ntej lub hlis no uas nws tau ua tiav cov kev txawj ntse hloov pauv hloov ntawm nws cov polyvinyl tshuaj tov khoom ntau lawm. Los ntawm kev qhia txog cov tshuab tswj tsis siv neeg thiab cov khoom siv cov zis ntau lawm, nws kuj tseem siv tau cov zis siv hluav taws xob ntau ntxiv, ua tiav qhov kev sib tw tshiab hauv kev tsim khoom ntsuab. Qhov kev ntsuas no tseem qhia txog kev tshawb nrhiav kev ua haujlwm ntawm kev lag luam hauv kev lag luam tam sim no kom nce ntxiv cov txheej txheem ntau dua, ua kom zoo dua cov txheej txheem kev ua lag luam ntau dua. Hauv daim ntawv thov teb, polyvinyl chloride, cia siab rau nws cov khoom siv lub cev thiab tshuaj zoo heev, txuas ntxiv nthuav nws thaj chaw ua lag luam. Kev lag luam kev tsim kho tseem yog cov kev siv ntau tshaj plaws ntawm polyvinyl chloride, thiab nws yog dav siv nyob rau hauv ntau hom cov raj, thiab cov khoom kho kom zoo nkauj, thiab kho kom zoo nkauj cov ntaub ntawv kho kom zoo nkauj. Nrog rau kev nce qib ntawm lub teb chaws infrastructure kev tsim kho thiab qhov kev thov maj mam ntawm cov khoom lag luam av, qhov kev thov rau polyvinyl chloride cov khoom tau hais tias cov qauv ntawm kev loj hlob ntawm kev loj hlob. Piv txwv li, nyob rau hauv qhov tsis ntev los no loj-teev nroog loj hauv nroog tsim kho thiab tiv thaiv kev ua kom dej huv thiab cov tshuaj tiv thaiv zoo heev thiab kev ua tau zoo ntawm kev ua tau zoo los ntawm lub phiaj xwm sab. Tsis tas li ntawd, polyvinyl chloride kuj yog cov kev tawm hauv cov teb tawm xws li kev kho mob thiab hluav taws xob. Hauv kev kho mob kev lag luam, tshwj xeeb kho cov kev kho mob polyvinyl chloride yog dav siv los tsim cov khoom siv kho mob uas muaj pov tseg, cov hnab ntshav, thiab tus kho mob ntshav. Vim tias nws muaj zoo transparency, yooj yim dua, thiab biocompatibility, nws muab kev yooj yim rau kev ua haujlwm kho mob thiab xyuas kom cov neeg mob. Hauv daim teb hluav taws xob, polyvinyl chloride, raws li cov khoom siv insulating rau cov khoom siv hluav taws xob, ua kom cov ntaub ntawv hluav taws xob zoo niaj hnub rau cov ntaub ntawv zoo niaj hnub no. Txawm li cas los xij, kev txhim kho ntawm polyvinyl chloride kev lag luam tsis yog txhua tus caij nkoj du. Tawm tsam lub nraub qaum ntawm cov kev tiv thaiv nruj ib puag ncig ib puag ncig, qhov teeb meem emission monomer uas yuav tsim muaj cov pa phem ntawm cov tshuaj muaj kuab lom yog nyob rau hauv kev saib xyuas stricter. Txhawm rau kom ua tau raws li qhov kev sib tw no, cov koom haum kev lag luam ua haujlwm npaj cov khoom lag luam kom huv si, txhawb nqa cov khoom lag luam kom huv si, kom cov neeg lag luam kom huv si, kom ua rau cov khoom lag luam kom huv si kom ntseeg tau tias yuav ua li cas thiaj li muaj kuab paug ua raws cov qauv. Nyob rau tib lub sijhawm, qee cov cheeb tsam kuj tau qhia txog cov cai txhawb nqa kev lag luam, kev lag luam cov kev lag luam ib puag ncig, coj kev lag luam los hloov ntawm ntsuab thiab muaj kev txhim kho kom loj hlob. Hais txog kev ua lag luam, tus nqi ntawm polyvinyl chloride tau hloov pauv rau qee qhov tsis ntev los no. Cuam tshuam los ntawm ntau yam xws li kev hloov pauv hauv cov roj av thoob ntiaj teb, thiab cov khoom siv tau ua tiav ntawm cov txheej txheem polyvinyl, tom qab ntawd ntog, thiab tom qab ntawd muab tso rau hauv lub hli dhau los. Kev lag luam kws tshuaj ntsuam xyuas taw qhia tias txawm hais tias muaj qhov tsis txaus ntseeg hauv kev lag luam tam sim no, nrog kev ua lag luam ntev dua, thiab nws pom zoo nyob rau hauv ib qho kev hloov kho hauv ntiaj teb thiab qhia tau tias muaj ntau yam nyob rau hauv lub xyoo tom ntej. Zuag qhia tag nrho, nyob rau hauv lub ntsej muag ntawm ob lub hau kev thiab kev cov nyom, cov kev ntsuas zoo tshaj plaws xws li kev tsim kho thev naus laus zis, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab kev tiv thaiv ib puag ncig, thiab cov kev tiv thaiv ib puag ncig. Nws lub neej yav tom ntej kev txhim kho yuav tsis ntseeg tias muaj kev cuam tshuam zoo heev ntawm kev lag luam kev lag luam thiab muaj feem cuam tshuam nrog kev lag luam hauv cov lag luam.
