Polyvinyl chloride (PVC) tau siv dav hauv ntau qhov kev lag luam vim nws cov khoom siv tau yooj yim, ua tau yooj yim, thiab cov txiaj ntsig zoo. Kev ua tiav thiab nthuav dav ntawm nws qhov kev ua tau zoo yog nyob ntawm kev siv ua ke ntawm ntau yam additives. Daim ntawv thov ntawm PVC additives npog tag nrho cov saw los ntawm kev hloov pauv hloov pauv mus rau kev ua haujlwm ntawm cov khoom kawg, suav nrog ntau yam xws li kev tsim kho, ntim khoom, hluav taws xob, kev thauj mus los, kev kho mob, thiab cov khoom siv niaj hnub, los ua lub hauv paus tseem ceeb txiav txim siab siv tau thiab kev lag luam kev sib tw ntawm cov khoom.
Hauv kev tsim kho, PVC profiles, cov kav dej, cov ntawv, thiab cov yeeb yaj kiab feem ntau siv kev sib txuas ntawm cov khoom siv hluav taws xob, kev hloov pauv, thiab cov kev pabcuam ua haujlwm kom ua tau raws li qhov yuav tsum tau ua ntev ntev - huab cua tsis kam, siab zog, thiab kev ua haujlwm zoo. Qhov rooj thiab qhov rais profiles yuav tsum tau tswj qhov seem stability thiab nto smoothness nyob rau hauv siab - kub extrusion tej yam kev mob, yog li yuav tsum tau nruj me ntsis raws li kev cai rau cov cua sov stabilization thiab lubrication systems. Cov kav dej thiab cov kav dej, ntxiv rau qhov siab thiab kev tiv thaiv corrosion, kuj tseem xav tau cov kev hloov pauv los txhim kho qis- qhov kub thiab txias, ua kom muaj kev nyab xeeb siv hauv qhov chaw txias. Cov ntaub thaiv dej tsis zoo thiab cov yeeb yaj kiab zoo nkauj feem ntau ua ke nrog cov yas yas thiab lub teeb stabilizers kom sib npaug yooj yim thiab tiv thaiv UV aging.
Hauv kev lag luam ntim, hloov pauv PVC zaj duab xis thiab cov ntawv txheeb tau siv dav hauv cov khoom noj, tshuaj, thiab cov khoom siv niaj hnub ntim, suav nrog cling zaj duab xis, blister packs, thiab cov txheej hauv cov ntaub ntawv sib xyaw. Cov khoom no qhia txog kev tsiv teb tsaws chaw tsawg, tsis muaj ntxhiab tsw, thiab kev sib khi zoo, yog li feem ntau siv cov yas zoo ib puag ncig thiab calcium-zinc heat stabilizers, ntxiv nrog cov tshuaj tua kab mob kom ntev lub neej txee. Rigid PVC kuj muaj qhov chaw nyob rau hauv lub raj mis ntim thiab blister ntim, yuav tsum tau kev pab ua kom zoo yaj ntws thiab xyuas kom meej molding precision thiab pob tshab.
Hauv cov khoom siv hluav taws xob thiab hluav taws xob, qhov ntau ntawm PVC additives txuas mus rau nplaim taws, rwb thaiv tsev, thiab kub tsis kam. Hlau thiab cable sheathing cov ntaub ntawv yuav tsum tau ntxiv cov nplaim retardants zoo heev thiab cov pa luam yeeb suppressants kom txo tau hluav taws kub thiab ua tau raws li cov kev cai ntawm kev nyab xeeb; Cov ntaub ntawv rwb thaiv tsev tsom rau hluav taws xob ruaj khov thiab tiv thaiv kev laus ntawm corona, feem ntau siv cov cua sov stabilizers thiab antioxidants. Cov khoom siv hluav taws xob hauv tsev thiab cov khoom sib txuas kuj tso siab rau cov kev hloov pauv los txhim kho kev tiv thaiv txhua yam.
Hauv kev thauj mus los, PVC yog siv rau hauv automotive tha xim sab hauv films, sealing strips, hoses, thiab tiv thaiv txheej, npog daim ntaub ntawv yuav tsum tau roj kuj, abrasion kuj, thiab huab cua tsis kam. Cov ntawv thov no feem ntau ntiav cov neeg tsiv teb tsaws chaw -cov yas resistant thiab cov tshuab ua kom ruaj khov, nrog rau kev sib ntxiv ntawm lub teeb stabilizers los tiv thaiv tshav ntuj thiab ozone kev laus, ua kom muaj kev ncaj ncees ntawm cov tsos thiab ua haujlwm ntev - kev pabcuam.
Cov chaw kho mob thiab kev tu cev tso cai rau kev nyab xeeb dua rau cov khoom ntxiv. Infusion tubing, hnab ntim ntshav, hnab looj tes pov tseg, thiab cov yeeb yaj kiab kho mob yuav tsum siv qis - cov tshuaj tiv thaiv toxicity stabilizers thiab plasticizers uas ua tau raws li cov qauv tshuaj pharmacopoeia lossis cov khoom noj khoom haus los tiv thaiv kev tso tawm cov tshuaj phem thiab tiv thaiv kev noj qab haus huv thiab kev nyab xeeb ntawm cov neeg mob thiab cov neeg siv.
Cov khoom siv niaj hnub xws li khau, tawv tawv, cov khoom ua si, thiab cov khoom siv ncaws pob dav siv cov mos mos ntawm PVC. Lawv cov additives muaj xws li yasizers los txhim kho txhais tes, kev hloov kho los txhim kho folding tsis kam, thiab cov xim thiab lub teeb stabilizers rau impart xim thiab lightfastness.
Zuag qhia tag nrho, daim ntawv thov ntau yam ntawm PVC additives spans ntau yam scenarios nyob rau hauv cov khoom siv, cov khoom siv, thiab cov khoom siv. Lawv cov qauv tsim nyog tsis yog tsuas yog hais txog qhov tsis txaus ntawm kev ua thiab siv PVC cob tab sis kuj ua rau cov khoom lag luam txhim khu kev qha nyob rau hauv ib puag ncig tshwj xeeb. Nrog rau kev nce qib ntawm ntsuab thiab siab - kev ua tau zoo tiam sis, daim ntawv thov ntawm cov additives yuav txuas ntxiv mus rau qhov tsis tshua muaj kev cuam tshuam ib puag ncig, kev ua haujlwm siab, thiab kev txawj ntse, muab kev txhawb zog rau kev nkag mus tob ntawm PVC hauv ntau yam lag luam.
