Cov txiaj ntsig thiab qhov tsis zoo ntawm cov tshuaj stabilizers ntsev txhuas

Cov txiaj ntsig ntawm cov tshuaj stabilizers ua los ntawm cov ntsev txhuas muaj xws li:
1. Kev ruaj khov zoo thermal: Nrog rau kev muaj peev xwm chelating, nws tuaj yeem hloov cov chlorine atoms tsis ruaj khov, cov ntsiab lus hlau siab, thiab muaj peev xwm nqus tau HCl.
2. Kev rwb thaiv hluav taws xob zoo heev: Tus nqi qis.
3. Kev tiv thaiv lub teeb zoo heev: Qee hom muaj lubricity zoo. Xws li lead dihydrogen phosphate, nws muaj kev ruaj khov zoo, antioxidant thiab UV shielding effects, thiab tuaj yeem muab cov profiles nrog kev ruaj khov lub teeb zoo thiab kev ruaj khov sab nraum zoov thermal oxygen, nrog rau qhov du ntawm qhov chaw. Kev sib xyaw nrog TiO2 tuaj yeem txo cov UV absorbers thiab antioxidants siv, thiab Hechuan yog lub kaw lus ruaj khov siv dav tshaj plaws hauv PVC profiles hauv Suav teb.
4. Kev ua tau zoo: Haum rau ntau yam kev ua haujlwm thiab muaj cov xim dawb.
Cov qhov tsis zoo ntawm cov tshuaj stabilizers muaj xws li:
1. Cov hmoov av loj: Thaum siv, muaj ntau cov hmoov av thiab ntau qhov ntsuas, uas tuaj yeem ua rau muaj qhov yuam kev ntsuas thiab muaj kev cuam tshuam loj rau qhov zoo ntawm cov profiles, ua rau muaj kuab paug. Kev ua pa ntawm cov hmoov av yog lom rau tib neeg lub cev.
2. Qhov feem pua ​​ntawm kev siv xim xiav xiav hloov pauv ntau ntxiv.
3. Cov ntsev monomer lead yuav lwj nrog PVC resin hauv qhov profile los tsim HCl thiab PbCl2: nws yuav ua rau cov hlau ions nag tas li. Thaum lawv mus rau saum npoo ntawm qhov profile, hauv thaj chaw uas muaj cov pa phem sulfur ntau, cov pa phem sulfurization yuav tshwm sim, ua rau cov profile hloov pauv. Yog li ntawd, cov neeg sawv cev txheej txheem lead cadmium ion, cov neeg sawv cev chelating, thiab lwm yam yuav tsum tau ntxiv rau cov mis ntsev lead. Lawv lub luag haujlwm yog tsim cov khoom sib xyaw nrog cov khoom tsis huv xws li chlorides tsim los ntawm qhov profile, tiv thaiv cov hlau chlorides tsis sib xws, thiab tiv thaiv cov pa phem sulfurization thiab hloov pauv.
4. Kev tawg tsis zoo: Cov tshuaj ua kom ntsev tsis muaj zog muaj kev tawg tsis zoo.
5. Muaj tshuaj lom heev: Cov tshuaj ua kom cov ntsev ua haujlwm ruaj khov muaj tshuaj lom heev.
6. Cov yam ntxwv xim pib: Cov tshuaj ua kom cov ntsev ua kom ruaj khov muaj cov yam ntxwv xim pib, ua rau nws nyuaj rau tau txais cov khoom pob tshab thiab cov khoom uas muaj xim ci ntsa iab.
7. Tsis muaj roj nplua nyeem: Cov tshuaj ua kom cov ntsev tsis muaj roj nplua nyeem thiab yooj yim rau cov pa phem sulfur.
Hauv kev xaus, cov tshuaj stabilizers ua los ntawm cov ntsev txhuas muaj cov txiaj ntsig tshwj xeeb hauv kev ua cov yas, tab sis kuj muaj cov teeb meem tseem ceeb uas tsis tuaj yeem tsis quav ntsej. Hauv kev siv ua haujlwm, nws yog ib qho tsim nyog los xav txog cov yam no thiab ua cov kev ntsuas kom kov yeej lawv cov teeb meem.
