Iithegi zeMveliso

Yintoni iAntioxidant 626 CAS 26741-53-7?

Le mveliso ngumgubo omhlophe we-crystalline kunye ne-melting point ye-160-175 ° C, i-flash point ye-168 ° C, kunye nendawo yokutshisa i-421 ° C. Inyibilika ngokulula kwizinyibilikisi ze-organic ezifana ne-toluene, i-methyl chloride, kunye ne-chloroform, i-soluble kancinane etywaleni, kwaye ayinyibiliki emanzini. I-Antioxidant 626 yimpuphu emhlophe ukuya emhlophe kunye nokuguquguquka okuphantsi kunye nokusebenza okuphezulu. Ihlala isetyenziswa ngokudibeneyo ne-phenol antioxidants ethintelweyo.

Isicelo

1. I-Antioxidant 626 isetyenziswa ikakhulu ekudibaneni nasekusetyenzweni kweeplastiki ezahlukeneyo ezifana nepolypropylene, ipolyethylene, i-ABS, ifayibha yepolycarbonate kunye nepolyester resin. ...
2. I-Antioxidant 626 i-phosphite encedisa i-antioxidant ene-volatility ephantsi, enokuthintela ngokufanelekileyo i-polymer discoloration, ukunciphisa izinga lokuchithwa kwe-polymer, kunye nokuphucula ukuxhathisa kwe-resin kwi-gas fading. Ilungele ngokukodwa i-polyolefins kunye ne-olefin copolymers, i-polycarbonate, i-polyamide kunye nezinye iiplastiki zobunjineli, kunye nerabha, iingubo kunye ne-adhesives. Ukongezwa kwe-antioxidant ye-626 kunokuphucula kakhulu ukuzinza kwezinto eziphathekayo, kwaye isetyenziswa ngokubanzi ekuqhutyweni kwe-polyethylene, i-polypropylene, i-ethylene-vinyl acetate copolymer, i-polystyrene, i-polyvinyl chloride kunye nezinye i-thermoplastics kunye ne-elastomers. phakathi. Ukongeza, i-antioxidant 626 inokuthintela okugqwesileyo kokuguquka kombala okubangelwa kukukhanya kunye nobushushu, kunye nesiphumo esithile sokuzinzisa ukukhanya, okunokuphucula ukukhanya, ukuzinza kwe-thermal, amandla omatshini kunye nokuzinza kombala wemveliso, ngaloo ndlela ukwandisa ubomi bemveliso. imveliso.
3. I-Antioxidant 626 ineempawu zeekhemikhali ezizinzile kunye nokuhambelana kakuhle kunye neepolymers ezininzi. Yinto esebenzayo ye-phosphite encedisa i-antioxidant. Ukusetyenziswa kwayo akukwazi nje ukuphucula ukuzinza kokulungiswa kwezinto, kodwa nokuphucula ukukhanya, ukuzinza kwe-thermal, amandla omatshini kunye nokuzinza kombala weemveliso. Sisongezo esibalulekileyo esisetyenziswa ngokubanzi kushishino lweplastiki.
