PVC yog hloov cov ntaub ntawv tsoos xws li ntoo, hlau, ua pob zeb ua thiab av nplaum hauv ntau daim ntawv thov.
Versatility, tus nqi ua tau zoo thiab cov ntaub ntawv zoo tshaj plaws ntawm kev siv txhais tau tias nws yog qhov tseem ceeb tshaj plaws polymer rau 60 feem pua ​​ntawm European PVC ntau lawm hauv 2006.

Polyvinyl chloride, pvc, yog ib qho ntawm cov kev nyiam plastics uas nrov tshaj plaws hauv tsev thiab kev tsim kho. Nws yog siv nyob rau hauv dej haus dej thiab khib nyiab dej, cov ntawv sib dhos thiab cov ntaub ntawv vov tsev, xaim rau cov ntoo niaj hnub xws li ntoo, hlau thiab iav. Cov khoom no feem ntau sib dua, tsis tshua kim thiab muab ntau yam kev ua tau zoo.

Muaj zog thiab lub teeb
PVC qhov kev txhaum ua tsis kam, lub teeb yuag, cov siv zog zoo thiab tawv yog qhov tseem ceeb yog qhov tseem ceeb rau nws siv hauv kev siv tsev thiab kev siv khoom siv.

Yooj yim rau nruab
PVC tuaj yeem raug txiav, puab, welded thiab koom nrog tau yooj yim hauv ntau yam qauv. Nws lub teeb hnyav txo cov phau ntawv tuav cov teeb meem nyuaj.

Ruaj khov
PVC yog tiv taus huab cua, tshuaj rotting, corrosion, poob siab thiab puas. Nws yog yog li ntawd kev xaiv zoo tshaj plaws rau ntau qhov sib txawv ntev-lub neej thiab cov khoom sab nraum zoov. Qhov tseeb, nruab nrab thiab cov ntawv thov ntev ntev rau qee qhov 85 feem pua ​​ntawm pvc ntau lawm hauv lub tsev thiab kev tsim kho hauv tsev.

Piv txwv li, nws kwv yees tau tias ntau dua 75 feem pua ​​ntawm cov kav dej hauv lub neej nyob rau hauv ntau tshaj ntawm 40 xyoo nrog kev ua haujlwm muaj txiaj ntsig nyob ntev txog 100 xyoo. Hauv lwm cov ntawv thov xws li lub qhov rais profiles thiab cable rwb thaiv tsev, kev tshawb fawb qhia tau tias ntau dua 60 feem pua ​​ntawm lawv tseem yuav ua lub neej ntau tshaj 40 xyoo.

Nqi-Zoo
PVC tau yog cov khoom siv nrov rau kev siv cov ntawv thov rau xyoo los vim nws cov khoom siv lub cev thiab cov txuj ci uas muab cov nqi zoo tshaj plaws. Raws li cov khoom siv nws yog kev sib tw heev nyob rau hauv cov nqe lus ntawm tus nqi, tus nqi no tseem txhim kho los ntawm cov khoom xws li nws cov kav dej thiab kev saib xyuas tsawg.

Khoom Siv Kom Zoo
PVC yog tsis muaj tshuaj lom. Nws yog cov khoom siv nyab xeeb thiab cov khoom muaj txiaj ntsig zoo uas tau siv rau ntau dua ib nrab xyoo. Nws tseem yog neeg ntiaj teb

feem ntau tshawb nrhiav thiab ua kom tiav cov yas sim. Nws ua tau raws li cov qauv thoob ntiaj teb rau kev nyab xeeb thiab kev noj qab haus huv rau ob qho tib si cov ntawv thov uas nws tau siv.

Txoj kev kawm 'kev sib tham ntawm qee qhov teeb meem scientific ntsig txog kev siv ntawm ib puag ncig ntawm Australia

Hloov chaw ntawm PVC los ntawm lwm cov ntaub ntawv ntawm ib puag ncig thaj chaw nrog tsis muaj kev tshawb fawb ntxiv lossis cov txiaj ntsig ua pov thawj yuav ua rau muaj nqi siab dua. Piv txwv li, raws li ib feem ntawm kev kho vaj tse kev kho vaj tse nyob rau ntawm Bielefeld hauv lub teb chaws Yelemees, nws tau kwv yees li kev nce qib li 2,250 euro rau qhov nruab nrab ntawm ob chav tsev.

Kev txwv ntawm pvc siv hauv kev siv cov ntawv thov yuav tsis tsuas yog muaj kev cuam tshuam tsis zoo nyiaj, xws li muaj kev pheej yig ntawm cov tsev pheej yig.

Hluav taws kub tiv thaiv
Zoo li tag nrho lwm cov ntaub ntawv organic siv rau cov tsev, suav nrog lwm cov plastics, ntoo, textiles thiab lwm yam, PVC cov khoom lag luam yuav hlawv thaum raug hluav taws. PVC cov khoom tab sis yog tus kheej-extinguishing, piv txwv li yog tias qhov chaw nres tsheb lawv yuav tsum tsis txhob hlawv. Vim tias nws cov chlorine cov chlorine cov ntsiab lus PVC cov khoom muaj cov yam ntxwv kev nyab xeeb, uas zoo heev li. Lawv yog qhov nyuaj rau zes, ntau lawm kev kub yog qhov sib piv cov khoom muaj thiab lawv zoo li char es tsis yog tsim flaming ntws.

Tab sis yog tias muaj hluav taws kub loj dua hauv lub tsev, PVC cov khoom lag luam yuav hlawv thiab yuav emit cov tshuaj lom zoo li txhua cov khoom siv organic.
Qhov tseem ceeb tshaj plaws cov kua txob siab tau tso tawm thaum hluav taws yog carbon monoxide (co), uas yog lub luag haujlwm rau 90 txog 95% ntawm kev tuag los ntawm cov hluav taws. Co yog Sneaky killer, vim peb tsis hnov ​​tsw thiab cov neeg feem coob tuag hauv hluav taws thaum tsaug zog. Thiab ntawm chav kawm co yog emritated los ntawm txhua cov organic cov ntaub ntawv, yuav yog ntoo, textile lossis plastics.

PVC raws li ib co lwm cov ntaub ntawv kuj tseem muaj cov acids. Cov pa hluav taws xob no tuaj yeem hnov ​​tsis hnov ​​tsw thiab ua rau tib neeg sim khiav ntawm hluav taws. Cov kua qaub tshwj xeeb, hydrochloric acid (hcl), txuas nrog rau hlawv PVC. Txhawm rau qhov zoo tshaj plaws ntawm peb txoj kev paub, tsis muaj tus neeg tua hluav taws tau ua pov thawj kev tshawb fawb tau raug kev txom nyem HCL lom.

Qee xyoo dhau los tsis muaj hluav taws kub tau sib tham tsis muaj cov tshuaj lom ua si ib qho tseem ceeb ntawm kev sib txuas lus thiab ntsuas cov khoos kas. Niaj hnub no peb paub tias Dioxins tau tawm hauv cov hluav taws tsis muaj kev cuam tshuam rau cov neeg ua raws li cov kev tshawb fawb tom qab cov qib kev ntsuas ntawm cov hluav taws kub tsis txhob nce tawm tsam cov qib tom qab. Qhov tseeb tseem ceeb tau raug lees paub los ntawm cov ntawv tshaj tawm raug cai thiab peb paub tias ntau lwm tus carcinogens tau tawm hauv txhua lub cev, xws li muaj kev phom sij ntau dua cov phom sij ntau tshaj li cov dioxins.

Yog li muaj cov laj thawj zoo heev rau siv PVC cov khoom lag luam hauv cov tuam tsev, vim tias lawv tau ua haujlwm zoo, thiab sib piv zoo nrog lwm cov ntaub ntawv ntawm hluav taws kev nyab xeeb.

Cov insulator zoo
PVC tsis ua hluav taws xob thiab yog vim li ntawd ib qho khoom siv zoo los siv rau cov ntaub ntawv hluav taws xob xws li rwb thaiv tsev sheathing rau cable.

Muaj peev xwm
Cov khoom siv lub cev ntawm PVC tso cai tsim qauv kev ywj pheej ntawm kev ywj pheej thaum tsim cov kev daws teeb meem tshiab thiab tsim cov khoom siv hloov chaw lossis hloov khoom dua.

PVC tau yog cov khoom siv uas nyiam tshaj plaws rau cov ntawv luam tawm scaffolding, sab hauv cov ntawv thav duab, cov khoom siv tshiab thiab cov hlua cable thiab ntau cov ntawv thov.
