PVC kub stabilizer (Core Application)
1.Mechanism ntawm kev ua:
Los ntawm kev ntes cov HCl tso tawm thaum lub sij hawm ua PVC, qhov degradation ntawm polymer chains yuav inhibited, yog li ncua cov khoom siv lifespan.
Qhov zoo:
Piv nrog cov hmoov txhuas ntsev stabilizers, nws tsis tshua muaj tshuaj lom thiab ib puag ncig tus phooj ywg, thiab ua raws li RoHS / REACH cov cai.
Nws muaj cov pob tshab siab thiab tsim nyog rau cov khoom pob tshab (xws li kev kho mob cov hlab ntsha thiab cov khoom ntim cov yeeb yaj kiab).
Dosage: 0.5-2% (Cov nyhuv zoo dua thaum ua ke nrog calcium-zinc stabilizer).
2. Organic synthesis catalyst
Esterification / condensation cov tshuaj tiv thaiv
Catalytic synthesis ntawm polyester resin thiab silicone roj hmab, nrog cov mob me me (80-120 ℃).
Case:
Thaum tsim cov yas yas (xws li phthalates), nws tuaj yeem hloov cov tshuaj sulfuric acid catalysts los txo cov kev mob tshwm sim.
3. Kho cov iav nto
Muaj nuj nqi:
Nws reacts nrog cov hydroxyl pawg ntawm cov iav nto los ua cov txheej hydrophobic (siv los tiv thaiv cov iav ntawm automotive iav thiab architectural iav).
Txheej txheem: Txau nrog 0.1-0.5% tov thiab tom qab ntawd kub thiab kho (150-200 ℃).
