2,4,6-Tri-tert-butylphenol CAS:732-26-3
I-2,4,6-Tri-tert-butylphenol, eyaziwa ngokuba yi-TTBP, i-crystalline eqinile engenambala kunye ne-organic chemical formula C18H24O.Iveliswa ngenkqubo engqongqo ukuqinisekisa ukucoceka kwayo kunye nokuhambelana.Ikhemikhali ine-molecular weight ye-256.38 g / mol kwaye inozinzo oluhle kakhulu kunye nokuchasana nokushisa, i-oksijeni kunye nezinto ezahlukeneyo zokusingqongileyo.
I-TTBP isetyenziswa ngokuyintloko njenge-antioxidant, iyenza ibe yinxalenye ebalulekileyo yamashishini amaninzi.Ukuzinza kwayo okugqwesileyo kwe-oxidation kunceda ukwandisa ubomi kunye nokusebenza kweentlobo ezininzi zeemveliso, kuyenza ilungele abavelisi.Ukususela kwiimveliso zerabha ukuya kwizongezo zepetroli kunye neengubo zamashishini, ukusetyenziswa kwe-TTBP kubanzi kwaye kuyahluka.
Inkcazo eneenkcukacha:
1. Iimpawu ze-Antioxidant:
I-2,4,6-Tri-tert-butylphenol isebenza njenge-antioxidant enamandla, inqanda iinkqubo ze-oxidation kunye nokuthintela ukuthotywa kwezinto ezibonakalayo kwi-oksijeni, ukushisa okanye kwi-UV radiation.Iipropathi zayo ezinamandla zokulwa ne-antioxidant ziyenza ilungele ukukhusela izinto eziphilayo ezinje ngerabha kunye neepolima ekuthotyweni kunye nokwandisa ubomi bazo beshelufu.Ukongeza, iphucula uzinzo kunye nokusebenza kweoyile yokuthambisa, iifutha kunye neeoyile ezahlukeneyo zeshishini.
2. Isizinzi se-UV:
Ukwakhiwa kweekhemikhali ze-TTBP kwenza ukuba ikwazi ukufunxa kwaye ichithe imisebe ye-UV, ukukhusela izinto kwimiphumo eyingozi yokukhanya kwelanga.Ngokuqhelekileyo isetyenziselwa ukuveliswa kweeplastiki, iipeyinti kunye neengubo, apho ukuxhathisa kwe-UV kubaluleke kakhulu ekugcineni ingqibelelo kunye nokubonakala kwemveliso egqityiweyo.Inciphisa ukuncipha, ukuqhekeka kunye nokuthotywa okubangelwa yimitha ye-UV, iqinisekisa ukuqina okuhlala ixesha elide kunye nobuhle.
3. Izithinteli:
I-TTBP iyasebenza njenge-polymerization inhibitor kumashishini ahlukeneyo.Isebenza ngokuthintela okanye ukucothisa ukubunjwa kwekhonkco le-polymer engafunwayo ngexesha lemveliso ye-monomer, iqinisekisa inkqubo ye-polymerization efanelekileyo.Oku kuyenza ibe licandelo elibalulekileyo ekwenziweni kwerabha eyenziweyo, izinto zokuncamathelisa kunye nezinye iimveliso zepolymer, ukuthintela ukudityaniswa okungafunwayo kunye nokuqinisekisa umgangatho wemveliso ofunekayo.
Isishwankathelo:
Iimpawu ezigqwesileyo ze-2,4,6-tri-tert-butylphenol (CAS: 732-26-3) yenza ukuba ibe yikhemikhali efunwa kakhulu kwiimarike.I-antioxidant yayo, i-UV-stabilizing kunye ne-polymerization-inhibiting properties inceda ukuphucula umgangatho wemveliso, ukuqina kunye nokusebenza.Njengomthengisi ohamba phambili, sizimisele ukunikezela nge-TTBP esemgangathweni ehlangabezana nemigangatho engqongqo yoshishino.Sithembe ukubonelela ngezisombululo ezithembekileyo nezisebenzayo kwiimfuno zakho zemichiza.Qhagamshelana nathi namhlanje ukuze ubuze malunga neprimiyamu yethu ye-2,4,6-Tri-tert-Butylphenol.
