I-MOCA,eyaziwa nangokuthi i-4,4′-Methylenebis (2-chloroaniline), iyikristalu yenaliti evulekile emhlophe kuya kophuzi okhanyayo ephenduka ibe mnyama uma ishiswa. Le nhlanganisela eguquguqukayo i-hygroscopic kancane futhi iyancibilika kuma-ketone nama-hydrocarbon aromatic. Kodwa okwenza i-MOCA ihluke ububanzi bayo bezicelo kanye nezici zomkhiqizo.
Izakhiwo zamakhemikhali:Ikristalu yenaliti evulekile emhlophe kuya kophuzi okhanyayo, efudumele ibe mnyama. I-hygroscopic kancane. Incibilika kuma-ketone nama-hydrocarbon anuka kamnandi.
I-MOCA isetshenziswa kakhulu njenge-ejenti yokuhlanganisa irabha ye-polyurethane ehlanganisiwe. Izakhiwo zayo zokuhlanganisa ziyenza ibe yisinqumo esihle kakhulu sokuthuthukisa amandla nokuqina kwezinto zerabha. Ngaphezu kwalokho, i-MOCA isebenza njenge-ejenti yokuhlanganisa izembozo ze-polyurethane kanye nezinamathiselo, inikeza ukunamathela okuthuthukisiwe kanye nokusebenza. Ngaphezu kwalokho, le nhlanganisela ingasetshenziswa ekwelapheni ama-resin e-epoxy, okwenza ibe yingxenye ebalulekile ezimbonini ezahlukahlukene.
Ngaphezu kwalokho, ukuguquguquka kwe-MOCA kudlulela ezinhlotsheni zayo ezahlukene. I-MOCA ewuketshezi ingasetshenziswa njenge-ejenti yokwelapha i-polyurethane ekushiseni kwegumbi, okunikeza ukulula kanye nokuguquguquka kokusetshenziswa. Ingasetshenziswa futhi njenge-ejenti yokwelapha i-polyurea yokufafaza, okwandisa ububanzi bayo bokusetshenziswa.
Izinzuzo kanye nezinhlelo zokusebenza：
Uma kukhulunywa ngensimu yerabha ne-polyurethane, ukuthola i-ejenti efanele yokuhlanganisa nokuhlanganisa kubalulekile. Yilapho i-MOCA (4,4'-Methylene-Bis-(2-Chloroaniline)) ithatha khona indawo ephambili. Ngezakhiwo zayo eziyingqayizivele kanye nobubanzi bezicelo, i-MOCA isibe yinto esemqoka ezimbonini ezahlukahlukene.
I-MOCA yaziwa ngokubonakala kwayo njengekristalu yenaliti emhlophe kuya kwephuzi elikhanyayo, ephenduka ibe mnyama uma ivezwa ekushiseni. Ngaphezu kwalokho, inezakhiwo ezincane ze-hygroscopic futhi iyancibilika kuma-ketone nama-hydrocarbon aromatic. Lezi zici ziyenza ibe yindawo efanelekile yokusetshenziswa ezinqubweni ezahlukene zokukhiqiza.
Enye yezinzuzo ezibalulekile ze-MOCA indima yayo njenge-ejenti yokuhlanganisa irabha ye-polyurethane ehlanganisiwe. Ngokuxhumanisa amaketanga e-polymer, i-MOCA ithuthukisa amandla nokuqina kwerabha. Lokhu kuqinisekisa ukuthi umkhiqizo wokugcina ungamelana nezimo ezinzima futhi ugcine ubuqotho bawo isikhathi eside.
Ngaphezu kwalokho, i-MOCA isebenza njenge-ejenti yokuxhumanisa enhle kakhulu yezembozo ze-polyurethane kanye nezinamathiselo. Ikhuthaza ukubopha kwamakhemikhali phakathi kwama-molecule e-polymer, okuholela ekugqokeni nasekunamathiseleni okubonisa ukusebenza okuphezulu. Kungakhathaliseki ukuthi kungezembozo ezivikelayo noma izinamathiselo zesakhiwo, i-MOCA inikeza amandla nokuzinza okudingekayo.
Ngaphezu kokusetshenziswa kwayo enjolobeni nasezimbozweni, i-MOCA ingasetshenziswa futhi ekupholiseni ama-resin e-epoxy. Ngokufaka inani elincane le-MOCA, i-resin ye-epoxy ingabhekana nokusabela okuxhumene, okuholela ezimpahleni ezithuthukisiwe zemishini nezokushisa. Lokhu kwenza i-MOCA ibe ithuluzi eliwusizo ezimbonini ezithembele kuma-resin e-epoxy emikhiqizweni yazo nasezinhlelweni zazo.
Ngaphezu kwalokho, kukhona uhlobo oluwuketshezi lwe-MOCA olwaziwa ngokuthi i-Moka. Lolu hlobo lungasetshenziswa njenge-ejenti yokwelapha i-polyurethane ekushiseni kwegumbi, okwenza kube lula kakhulu ezinqubweni zokukhiqiza. Ngaphezu kwalokho, i-Moka ingasebenza njenge-ejenti yokwelapha i-polyurea yokusetshenziswa kokufutha. Ukuguquguquka kwayo kanye nokulula kokusetshenziswa kwayo kwenza kube ukukhetha okudumile phakathi kwabakhiqizi.
Ukupakishwa nokugcinwa：
Ukupakisha:50kg/DRUM
Isitoreji：kufanele kube sendaweni epholile, eyomile futhi engenisa umoya.
Ukuzinza:Ukushisa nokuba mnyama, umswakama omncane. Akukho ukuhlolwa okuningiliziwe kwezifo eShayina, futhi akuqiniseki ukuthi lo mkhiqizo unobuthi futhi uyingozi. Idivayisi kufanele iqiniswe ukuze kuncishiswe ukuthintana nesikhumba nokuphefumula kusuka endleleni yokuphefumula, futhi kuncishiswe ukulimala emzimbeni womuntu ngangokunokwenzeka.
Isifinyezo：
Ngamafuphi, i-MOCA (4,4'-Methylene-Bis-(2-Chloroaniline)) iyi-ejenti ehlanganisa izinto eziningi futhi ewusizo kakhulu. Uhlu lwayo olubanzi lwezicelo embonini yerabha, izembozo, kanye nezinamathiselo ze-polyurethane luyenza ibe yisinqumo esithandwa kakhulu ngabakhiqizi. Njengoba inekhono layo lokuthuthukisa amandla, ukuqina, kanye nokubopha kwamakhemikhali, i-MOCA ngokungangabazeki idlala indima ebalulekile ekuqinisekiseni ikhwalithi kanye nokusebenza kwemikhiqizo ehlukahlukene.
