Yintoni iChimassorb 944 Cas 71878-19-8?

I-Chimassorb 944 (CAS 71878-19-8) sisithintelo sokukhanya kwe-amine esinobunzima obuphezulu (HALS).

I-UV Absorber 944 sisithambisi sokukhanya se-amine esinobunzima obuphezulu esifakwe i-polymer, esine-volatility ephantsi, ukumelana nokufuduka, kunye nokumelana nobushushu obuphezulu. Amaqela e-amine athintelweyo kwisakhiwo seekhemikhali se-UV 944 anokubamba ngempumelelo ii-free radicals, ngaloo ndlela edlala indima ekuzinziseni ukukhanya.

Ukusebenza kakuhle kwe-polymeric kuthintele ukuzinzisa ukukhanya kwe-amine, ukuguquguquka okuphantsi, ukufuduka okuphantsi, ukuzinza kobushushu kunye nefuthe lokulwa ne-oxidation, ukusebenzisana nee-antioxidants kunye nee-UV absorbers. I-UV Absorber 944 ingafakwa kwi-polyolefins, ii-olefin copolymers, kodwa nakwi-polyphenylene ether complexes, i-polyoxymethylene, i-amides, i-PVC ethambileyo neqinileyo kunye ne-PVC blends.

Isicelo

I-Chimassorb 944 inokuphucula ngokufanelekileyo uzinzo lokukhanya kweemveliso ezibhityileyo, ingakumbi iimveliso zefayibha kunye nefilimu. I-UV 944 ikwafanelekile kwiimveliso ezinqamlezileyo kunye neemveliso ze-polyethylene.

Iindawo zokusetyenziswa kwe-UV Absorber 944 ziquka iiplastiki ze-polyolefin (ezifana ne-PP, PE), ii-olefin copolymers (ezifana ne-EVA), kunye nemixube ye-polypropylene (PP) kunye nee-elastomers, njl. Ukongeza, i-UV Absorber 944 ingasetyenziswa nakwimixube ye-polyoxymethylene (POM), i-polyamide (PA), i-polyurethane (PU), i-PVC eguquguqukayo neqinileyo, kunye ne-PVC. I-Chimassorb 944 ikwasebenza kakhulu kwizicelo ezikhethekileyo ze-elastomers kunye ne-adhesives ezisekelwe kwi-styrene.

Iimbonakalo

✅I-Chimassorb 944 inokukhanya okuzinzileyo kwaye inokuthintela ngempumelelo ukubola, ukutshintsha kombala kunye nokuqhekeka kweplastiki okubangelwa yimisebe ye-ultraviolet.
✅I-UV Absorber 944 ineempawu ezilungileyo zokulwa nokutsalwa kwenkunkuma kwaye ayithambekeli ekufudukeni kwiplastiki ngexesha lokusetyenziswa ixesha elide.
✅I-UV 944 ihambelana kakuhle kwaye ingasasazwa ngokulinganayo emzimbeni weplastiki ngaphandle kokuchaphazela ukusebenza kokucubungula kunye neempawu zomzimba neze-mechanical zeplastiki.
