Anti Aging Zaj duab xis

PVC anti-aging zaj duab xis yog tsim los siv raw cov ntaub ntawv nrog anti-aging additives los ntawm calendering, ua rau lub neej ntev dua piv rau li niaj zaus PVC zaj duab xis. Dibona tuaj yeem kho cov yeeb yaj kiab los tiv thaiv kev laus nrog cov tsis sib xws raws li cov neeg siv khoom xav tau.

PVC anti-aging zaj duab xis yog dav siv nyob rau hauv ntau yam kev siv, xws li:

Waterproof Enclosures thiab cov khoom
Vim nws qhov tshwj xeeb ruaj khov thiab dej tsis kam, PVC zaj duab xis yog qhov zoo tagnrho rau kev tsim cov khoom siv sab nraum zoov thiab sab hauv tsev thiab cov khoom siv, xws li canopies, tents, thiab da dej curtains.

Rooj tog thiab khoom siv npog
PVC anti-aging zaj duab xis yog zoo heev rau ua rooj tog npog thiab cov khoom tiv thaiv zoo li cov khoom noj khoom haus hnab thiab imitation tawv. Cov npog thiab cov khoom no yog weatherproof, yooj yim rau tu, thiab tuaj yeem laminated rau kev tiv thaiv ntxiv.

Windows thiab Siding
PVC zaj duab xis insulating thiab tshav kub-resistant zog, ua ke nrog nws durability, ua rau nws zoo meej rau lub qhov rais npog thiab siding.

Cov khoom ntim
Ob leeg nruj thiab yoog raws PVC zaj duab xis yog siv hauv kev lag luam ntim khoom. Flexible zaj duab xis yog siv rau tamper-resistant seals ntawm cov neeg siv khoom, khoom noj khoom haus, dej haus, thiab tshuaj, thaum rigid film yog siv rau ntim cov ntaub ntawv xws li clamshells.

PVC anti-aging zaj duab xis boasts ntau yam tseem ceeb, nrog rau siab tiv thaiv UV rays, acids, alkalis, roj, thiab ntau corrosive ntxhia tshuaj. Ntxiv qhov zoo ntawm PVC yas yog:

• Tsawg nqi ntau lawm
• Flexibility thiab cuam tshuam tsis kam
• Hluav taws xob rwb thaiv tsev zoo heev
• Tsis-flammable
• Yooj yim ntawm kev ua
• Siab pob tshab
• Ua haujlwm kub sealing
• Zoo toughness
• Uniform thermal shrinkage

Calendered
Txhawm rau tsim cov calendered PVC zaj duab xis, PVC hmoov yog tov nrog cov kua softener hauv ib lub zeb zoo. Cov sib tov yog ces extruded los ua ib homogeneous loj hu ua yaj. Cov txheej txheem no siv ob lub tshuab tig rov qab ua kom sov txog li 350 degrees Fahrenheit. Lub yaj yog kos rau hauv qhov sib txawv ntawm cov yob thiab flattened nyob rau hauv siab.

Ntxig
Cov txheej txheem casting pib nrog cov khoom siv raw. PVC resin yog thawj zaug sib xyaw nrog cov yas yas thiab stabilizer. Qhov sib tov no ces dhau los ntawm kev sib xyaw cov menyuam, uas pub nws mus rau extruder. Cov khoom siv tom qab xa mus los ntawm ntu calendered, qhov twg nws ncav cuag qhov kub ntawm 160 degree thiab 180 degree. Thaum kawg, cov khoom yog txias.

Kev sib xyaw
Ntau cov txheej txheem plastics tab tom tshawb nrhiav cov txheej txheem tshiab los txo cov nqi thaum sib xyaw PVC zaj duab xis. Polyvinyl chloride (PVC) thev naus laus zis pab ua kom tau raws li cov kev ua tau zoo. Peb koom tes nrog cov neeg siv khoom los txiav txim siab cov ntsiab lus zoo tshaj plaws rau lawv cov kev xav tau. Thaum tsim cov ntawv PVC los ntawm cov roj polymerizing, cov khoom siv tau dhau los ua ntau yam txheej txheem uas yuav tsum tau muaj tus neeg sawv cev pabcuam-cov tshuaj sib xyaw nrog ntau qhov rov ua dua tshiab txuas lub taub hau-rau-tail. Qhov theoretical molecular hnyav ntawm PVC yog li ntawm 30, 000 mus rau 95, 000. Ob qho tib si qhov nruab nrab molecular hnyav ntawm zaj duab xis thiab nws qhov kev faib tawm cuam tshuam rau nws cov khoom.

Kub Stabilizers
Thaum tshav kub kub stabilizers txhim khu PVC zaj duab xis tiv thaiv tshav kub laus, tshav ntuj, thiab huab cua. Cov additives no txhim kho cov yeeb yaj kiab lub cev thiab cuam tshuam nws cov nqi. Feem ntau, stabilizers yog muab rau hauv cov khoom sib xyaw uas muaj cov xab npum hlau, ntsev, thiab cov organic sib txuas. Lawv cov kev xaiv nyob ntawm qhov kawg siv ntawm PVC zaj duab xis, cov cai tswj kev pom zoo, thiab tus nqi.

Phthalate Plasticizers
Orthophthalates yog ib chav kawm ntawm cov tshuaj plasticisers siv hauv PVC thiab lwm yam ntaub ntawv. Lawv muaj nyob rau hauv ntau yam khoom siv niaj hnub thiab cov cuab yeej kho mob cawm siav. Qee qhov kuj tseem siv rau hauv kev lag luam uas tsis yog PVC. Cov plasticisers no tau muab cais ua phthalates siab lossis qis raws li lawv cov khoom toxicological thiab kev cai lij choj.
