Iyini i-Light Stabilizer-944 CAS 70624-18-9?

Isiqinisi sokukhanya i-UV-944 sinamandla okumelana nokukhishwa, ikakhulukazi esifanele imikhiqizo emincane, njengemicu namafilimu; Singathuthukisa futhi ukumelana nokuguga kwe-oxygen yokushisa kwezinto. Isiqinisi sokukhanya i-HS-944 simhlophe kuya kwezinhlayiya eziphuzi ezikhanyayo noma impuphu, iphuzu lokuncibilika lingu-100-135°C, isisindo sama-molecule singu-2000-3100, sinokuhambisana okuhle kakhulu, ukumelana nokukhishwa kanye nokuguquguquka okuphansi. Njengoba i-UV-944 iyisiqinisi sokuqina kwama-molecule esiphezulu, futhi i-molecule iqukethe inani elikhulu le-methylate kuphela, izinzile uma iphathwa nge-oxygen eshisayo.

I-Light Stabilizer-944 isetshenziswa kwifilimu ye-polyethylene ephansi, i-polypropylene fiber, i-polypropylene tape, ifilimu ye-EVA, i-ABS, i-polystyrene kanye nokupakishwa kokudla. I-Light stabilizer HS-944 ingeye-hindrable amine light stabilizer.

Izinzuzo zethu

1. Umphumela omuhle kakhulu wokuzinzisa ukukhanya: I-UV-944 ingavikela ngempumelelo izinto ze-polymer ekuvezweni kokukhanya kwe-ultraviolet kanye nokubola kwe-photo kanye nokuwohloka kokushisa okubangelwa ukuguga kokushisa kwesikhathi eside. Umphumela wayo wokuzinzisa ukukhanya udlula kakhulu owe-ultraviolet absorbers kanye ne-nickel-containing stabilizers, ikakhulukazi ezinhlelweni zombala lapho umphumela usobala khona.

2. Ukuhambisana okuhle nokusebenza kahle kokucubungula: Kuyizinto eziphuzi ezikhanyayo nezicwebezelayo ezinokuguquguquka okuphansi. Kuhambisana kahle nezinto ezahlukahlukene ze-polymer ezifana ne-PP, i-LDPE, i-HDPE, ne-PVC. Kungasakazwa kalula ku-polymer matrix ngaphandle kokuthinta ukubonakala nombala we-resin, futhi kusebenza kahle kakhulu kokucubungula.

3. Ububanzi bokusetshenziswa futhi buphephile futhi buthembekile: I-UV-944 ifanele izinhlobo ezahlukene zezinto ezifana namafilimu, imicu, nemikhiqizo ewugqinsi, futhi ingasetshenziswa kuma-polymer amaningi kufaka phakathi ama-polyolefin, ama-polyurethane, nama-polyamides. Okwamanje, ivunyiwe yi-FDA futhi ingasetshenziswa ekusetshenzisweni kokudla, okubonisa izinga elithile lokuphepha.
