Chii chinonzi Light Stabilizer-944 CAS 70624-18-9?

Chinosimbisa chiedza UV-944 chine simba rakanaka rekudzivirira kubviswa kwechinhu, kunyanya chakakodzera zvigadzirwa zvitete, zvakaita semafiber nemafirimu; Chinogonawo kuvandudza simba rekupisa kweokisijeni pakukwegura kwechinhu chacho. Chinosimbisa chiedza HS-944 chine zvidimbu zvichena zveyero kana upfu, chinonyunguduka 100-135°C, huremu hwemorekuru 2000-3100, chinoenderana zvakanaka, hachichinji uye hachina kusimba. Sezvo UV-944 iri simba guru rekudzivirira mamorekuru, uye molekyuru yacho ine methylate yakawanda chete, inogara yakasimba kana ikashandiswa neokisijeni inopisa.

Zvakanakira zvedu

1. Kubudirira kwekugadzirisa chiedza: UV-944 inogona kudzivirira zvinhu zvepolymer kubva pakuratidzwa nechiedza cheultraviolet uye kuora kwechiedza uye kuora kwekupisa kunokonzerwa nekukwegura kwenguva refu kwekupisa. Kubudirira kwayo kwekugadzirisa chiedza kunopfuura zvakanyanya kunobva kune zvinotora ultraviolet uye zvinogadzirisa nickel, kunyanya mumichina yepigment uko mhedzisiro yacho iri pachena.

2. Kushanda zvakanaka uye kushanda zvakanaka kwekugadzirisa: Chinhu cheyero yakajeka, chinoonekera, chine granular, chisina kusimba zvakanyanya. Chinoshanda zvakanaka nezvinhu zvakasiyana-siyana zvepolymer zvakaita sePP, LDPE, HDPE, uye PVC. Chinogona kupararira zviri nyore mupolymer matrix pasina kukanganisa kujeka uye ruvara rweresin, uye chine kushanda zvakanaka kwekugadzirisa.

3. Kushandiswa kwakasiyana-siyana uye kwakachengeteka uye kwakavimbika: UV-944 yakakodzera mhando dzakasiyana dzezvinhu zvakaita semafirimu, fibers, uye zvigadzirwa zvakakora, uye inogona kushandiswa kune akawanda mapolymer anosanganisira polyolefins, polyurethanes, uye polyamides. Panguva iyi, yakatenderwa neFDA uye inogona kushandiswa mukushandisa chikafu, zvichiratidza kuchengetedzeka kwakati.
