PVC qhov rais thiab qhov rooj yog cov khoom siv tseem ceeb hauv kev tsim kho niaj hnub no, muaj npe nrov rau lawv cov khoom siv ntau yam, ua haujlwm ntev, thiab siv tau zoo. Ua kev hloov pauv rau cov khoom siv ib txwm muaj xws li tooj liab, zinc, txhuas, thiab ntoo, lawv tau hloov pauv kev tsim vaj tsev.
Tsis tsuas yog PVC qhov rais thiab qhov rooj sib zog, tab sis lawv kuj khav theeb tshwj xeeb toughness, corrosion kuj, thiab impressive anti-aging zog. Lawv cov nqi pheej yig, ntau yam xim, thiab kev ruaj khov ua rau lawv muaj kev xaiv zoo tshaj plaws rau ntau yam kev siv, los ntawm cov tsev rau pej xeem mus rau cov tsev nyob.
Txhawm rau tsim qhov zoo U-PVC qhov rais thiab qhov rooj profiles, ob peb cov ntaub ntawv tseem ceeb yog siv:
- PVC cob: tshwj xeeb tsim nrog qib ntawm K66 thiab K68 kom ntseeg tau tias kev ua haujlwm zoo thiab ua haujlwm ntev.
- Filler: Zoo dua, Precipitated Calcium Carbonate (PCC) yog siv los txhim kho qhov tawv nqaij thiab txo cov nqi.
- PVC stabilizers: Cov kev xaiv muaj xws li txhuas-raws li ib-pob stabilizers lossis Calcium Zinc stabilizers los tswj cov txheej txheem kev ncaj ncees ntawm cov profiles.
- Internal lubricants: Qhov tseem ceeb rau kev ua haujlwm zoo, Calcium Stearate lossis Stearic Acid feem ntau ua haujlwm.
- Cov roj nplua nyeem sab nraud: Polyethylene (PE) wax ua kom zoo extrusion thiab nto tiav.
- Kev hloov pauv cuam tshuam: Ob leeg Chlorinated Polyethylene (CPE) 135A lossis Acrylic Impact Modifiers (AIM) tau ntxiv los txhim kho kev cuam tshuam.
- Acrylic processing pab: Txhim kho cov yaj lub zog thiab txhawb kev ua haujlwm.
- Pigments: Rutile Titanium Dioxide thiab Optical Brighteners muab cov xim ruaj khov thiab zoo nkauj txaus nyiam.
