Lub Teeb Stabilizer-944 CAS 70624-18-9 yog dab tsi?

Lub teeb stabilizer UV-944 muaj kev tiv thaiv zoo rau kev rho tawm, tshwj xeeb tshaj yog rau cov khoom nyias nyias, xws li cov fibers thiab cov yeeb yaj kiab; Nws kuj tseem tuaj yeem txhim kho qhov tsis kam ntawm cov pa oxygen thermal ntawm cov khoom. Lub teeb stabilizer HS-944 yog dawb rau cov khoom me me lossis hmoov daj, melting point 100-135 ° C, qhov hnyav molecular 2000-3100, nrog kev sib raug zoo heev, kev tiv thaiv kev rho tawm thiab kev hloov pauv tsawg. Txij li thaum UV-944 yog lub zog molecular stabilizer siab, thiab lub molecule tsuas muaj ntau ntawm methylate, nws ruaj khov thaum kho nrog cov pa oxygen kub.

Peb qhov zoo

1. Cov nyhuv zoo heev rau kev ruaj khov lub teeb: UV-944 tuaj yeem tiv thaiv cov khoom siv polymer los ntawm kev raug lub teeb ultraviolet thiab kev puas tsuaj ntawm photodegradation thiab thermal degradation los ntawm kev laus thermal ntev. Nws cov nyhuv ruaj khov lub teeb ntau dua li cov ultraviolet absorbers thiab nickel-muaj stabilizers, tshwj xeeb tshaj yog nyob rau hauv cov kab ke pigment qhov twg cov nyhuv yog pom tseeb dua.

2. Kev sib raug zoo thiab kev ua haujlwm zoo: Nws yog cov khoom siv pob tshab daj uas tsis muaj kev hloov pauv ntau. Nws muaj kev sib raug zoo nrog ntau yam khoom siv polymer xws li PP, LDPE, HDPE, thiab PVC. Nws tuaj yeem yooj yim tawg rau hauv cov polymer matrix yam tsis cuam tshuam rau qhov pob tshab thiab xim ntawm cov resin, thiab muaj kev ua haujlwm zoo heev.

3. Kev siv dav dav thiab muaj kev nyab xeeb thiab txhim khu kev qha: UV-944 yog qhov tsim nyog rau ntau yam ntaub ntawv xws li zaj duab xis, cov fibers, thiab cov khoom tuab, thiab tuaj yeem siv rau ntau yam polymers suav nrog polyolefins, polyurethanes, thiab polyamides. Lub caij no, nws tau txais kev pom zoo los ntawm FDA thiab tuaj yeem siv rau hauv cov ntawv thov sib cuag zaub mov, qhia txog qee qib kev nyab xeeb.
