Daim ntawv thov ntawm PVC txhuas ntsev stabilizer

PVC lead salt stabilizer yog ib qho thermal stabilizer uas siv ntau hauv kev ua polyvinyl chloride (PVC). Nws feem ntau ua kom cov khoom siv thermal stability zoo dua los ntawm kev ntes hydrogen chloride (HCl), thiab muaj kev rwb thaiv hluav taws xob zoo heev thiab cov nqi zoo. Nws cov chaw siv tseem ceeb suav nrog:
Cov xwm txheej tseem ceeb ntawm daim ntawv thov:
1. Cov khoom siv PVC tawv
Xws li cov kav dej, cov phaj, cov ntaub ntawv qhia, thiab lwm yam, tshwj xeeb tshaj yog rau cov khoom tsis pom kev (xws li cov hlau thiab cov hlua khi, cov kav dej ntws hauv tsev). Cov tshuaj stabilizers ua los ntawm cov ntsev txhuas tuaj yeem tiv thaiv kev puas tsuaj ntawm PVC thaum lub sijhawm ua haujlwm thiab txuas ntxiv lub neej ua haujlwm ntawm cov khoom.
2. Kev lag luam hlau thiab cable
Vim nws cov khoom siv hluav taws xob zoo heev, cov tshuaj stabilizers ua los ntawm cov ntsev txhuas tau siv dav hauv kev tsim cov khoom siv cable PVC.
Kev zoo ntawm kev siv tshuab:
Kev Txhim Kho Cov Ntxwv Ua Los Ntawm Cov Hlau Ua Ke: Cov ntsev ua los ntawm cov hlau ua ke nrog cov roj nplua nyeem los ntawm kev siv tshuab sib xyaw ua ke los tsim cov khoom tsis muaj hmoov av, txo cov hmoov av ua qias tuaj thiab txhim kho kev sib kis.
Kev siv nyiaj tsim nyog: Cov ntsiab lus hlau siab, muaj peev xwm nqus tau HCl, thiab kev hloov pauv kub dav dav, tsim nyog rau kev tsim khoom lag luam loj.
Kev Txwv thiab Lwm Yam Kev Hloov Pauv
Qhov teeb meem ntawm kev lom: Qhov hnyav ntawm cov hlau lead ua rau nws siv tsis tau rau hauv cov khoom siv sib cuag zaub mov, cov khoom siv kho mob, thiab lwm yam.
Kev hloov chaw ib puag ncig: Nrog rau qhov kev thov kom muaj kev tiv thaiv ib puag ncig ntau ntxiv, cov khoom lag luam uas tsis muaj tshuaj lom xws li calcium zinc composite stabilizers thiab organotin maj mam hloov cov ntsev txhuas.
Cov Lus Qhia Luv: Cov tshuaj stabilizers ua los ntawm cov hlau lead hauv PVC tseem muaj kev sib tw hauv cov teb kev lag luam ib txwm muaj, tab sis lawv qhov kev siv yuav tsum tau sib npaug nrog cov cai ib puag ncig. Cov thev naus laus zis ua los ntawm cov hlau lead tau tswj hwm nws txoj haujlwm hauv kev lag luam hauv cov xwm txheej tshwj xeeb los ntawm kev ua kom zoo dua cov mis thiab cov txheej txheem.
