Kev soj ntsuam ntawm lub luag haujlwm ntawm kev sib xyaw ntawm cov stabilizers hauv kev tsim cov khoom PVC cov kav dej thiab cov fittings | Phau ntawv qhia rau qhov ua kom zoo ntawm ib puag ncig tus phooj ywg PVC Adusitive Cormulas

Nrog rau kev siv thoob plaws ntawm cov kav dej pipes thiab fittings nyob rau hauv cov liaj teb ntawm cov chaw tsim dej thiab kev ua haujlwm hauv kev ua haujlwm, lawv cov huab cua tsis zoo thiab tiv thaiv kev lag luam tseem ceeb ntawm kev lag luam. Raws li cov tub ntxhais qeb ntawm PVC ua cov kev sib ntxiv, cov khoom sib xyaw ua ke ncaj qha txiav txim siab cov kav dej thiab cov fittings ntawm thermal kev txhim kho. Cov kab lus no tob rau kev tshawb xyuas cov kev tshawb fawb thiab cov qauv kev lag luam zinc thiab cov qauv kev ua kom muaj zog rau cov neeg siv khoom siv rau cov neeg tsim khoom.

1. Plaub lub luag haujlwm tseem ceeb ntawm kev sib xyaw ua kom ruaj khov: puv nkaus los ntawm kev siv khoom

• High-efficievicic stabal stabilizers: thaiv cov saw cov tshuaj tiv thaiv ntawm PVC degradation

PVC Resin yog nquag thab thiab embrittlement vim qhov kev tso tawm ntawm HCL thaum lub sij hawm high-ceev extrusion ua (160-200 ℃). Puas muaj stabilizers nruab nrab acidic cov tshuaj los ntawm cov nyhuv hlau (xws li cov khoom siv calcium) thiab cov epoxy

• Cov roj nplua nyeem ntawv tshuav: txo lub zog torque thiab kev siv hluav taws xob

Los ntawm kev piv ntawm cov roj nplua nyeem sab hauv (xws li cov roj nplua nyeem sab nraud) thiab cov viscosy tsis muaj zog, thiab cov phab ntsa tuab ntawm cov khoom siv ntawm UPVC tau zoo dua.

• Anti-oxidation thiab Washering Qhov Ntau Tshaj Plaws: Txuas lub neej ntawm cov kav dej sab nraum zoov

Ntxiv cov kev nqus cov roj ultraviolet (xws li titanium dioxide) thiab cov antioxidanes txhim kho cov kev ua kom muaj zog ntawm kev tawm tsam cov kev cai lij choj, tau ntsib cov kev cai AstM D1784 cov qauv.

• Kev ua raws ib puag ncig: Ntsib Cov Kev Cai Tswj Ntiaj Teb

Lead-dawb Composite Stabilizers (xws li calcium zinc series) tau dhau los ua ntawv pov thawj thiab NSF cov qauv dej haus, thiab tsim nyog rau cov khoom siv-qib ntau lawm xav tau.

2. Coj mus rau qhov sib npaug ntawm cov sib xyaw ua ke stabilizers ntxiv | PVC Yeeb Nkab Walmululation Optimization
Raws li ntawm PVC tus qauv Resin (xws li SG-5, SG-8), Ua Tshuaj Pwm (Excortion Kev Sib Tw tau pom zoo:

• General PVC kav: 1.8% -2.5% Compound Stabilizer (raws li 100% Resin)
• Cov huab cua siab tiv thaiv UPVV dej Pipes: 2.5% -3.2% + 0.5% -1% cuam tshuam hloov kho (xws li CPE)
• Cov Qauv Coj Ua Tus Ua Ntej Leada: calcium Zinc Stabilizer 2.8% -3.5% + ib qho kev ruaj khov (xws li hydroalcite)
• High-wather-walled Yeeb Nkab Extrusion: 3.0% -3.5% Cov Khoom Siv Lub Siab Lub Hlaub Txhaum Cai Stabound kom txo qis kev phom sij
