I-MOCA,eyaziwa nangokuthi 4,4′-Methylenebis(2-chloroaniline), iyikristalu yenaliti ekhanyayo emhlophe kuya kokuphuzi ephenduka ibe mnyama uma ishiswa.Le nhlanganisela ehlukahlukene ine-hygroscopic futhi incibilika kuma-ketone nama-hydrocarbon anephunga elimnandi.Kodwa yini eyenza i-MOCA ihluke ububanzi bayo bezinhlelo zokusebenza nezici zomkhiqizo.
Izakhiwo zamakhemikhali:ikristalu yenaliti enaliti emhlophe kuya kokuphuzi, eshisiswe ibemnyama.I-hygroscopic kancane.Incibilika kuma-ketone nama-hydrocarbon anephunga elimnandi.
I-MOCA isetshenziswa kakhulu njenge-ejenti efaka i-vulcanizing for cast polyurethane rubber.Izakhiwo zayo eziphambanisayo zikwenza kube ukukhetha okuhle kakhulu kokuthuthukisa amandla nokuqina kwezinto zenjoloba.Ukwengeza, i-MOCA isebenza njenge-ejenti exhumanisayo ye-polyurethane coatings nama-adhesives, enikeza ukunamathela nokusebenza okuthuthukisiwe.Ngaphezu kwalokho, le nhlanganisela ingasetshenziswa ukwelapha ama-epoxy resins, okuyenza ibe yingxenye ebalulekile ezimbonini ezihlukahlukene.
Ngaphezu kwalokho, ukuguquguquka kwe-MOCA kudlulela ezinhlotsheni zayo ezihlukene.I-MOCA ye-Liquid ingasetshenziswa njenge-ejenti yokwelapha i-polyurethane ekamelweni lokushisa, inikeza lula nokuguquguquka ekusetshenzisweni.Ingasetshenziswa futhi njenge-ejenti yokwelapha i-polyurea yokufafaza, iqhubeke nokwandisa ububanzi bayo bokusebenziseka.
Izinzuzo kanye nezicelo:
Uma kukhulunywa ngomkhakha wenjoloba ye-polyurethane ne-coatings, ukuthola i-ejenti efanele ye-vulcanizing ne-crosslinking kubalulekile.Kulapho i-MOCA (4,4'-Methylene-Bis-(2-Chloroaniline)) ithatha indawo emaphakathi.Ngezakhiwo zayo ezihlukile kanye nohlu olubanzi lwezinhlelo zokusebenza, i-MOCA isiphenduke isisekelo ezimbonini ezahlukahlukene.
I-MOCA yaziwa ngokubukeka kwayo njengekristalu enaliti ekhanyayo emhlophe kuya kokuphuzi ekhanyayo, eba mnyama lapho ichayeke ekushiseni.Ukwengeza, inezinto ezincane ze-hygroscopic futhi inyibilika kuma-ketone nama-hydrocarbon anephunga elimnandi.Lezi zici ziyenza ibe yikhandidethi elifanele ukuthi lisetshenziswe ezinqubweni ezihlukene zokukhiqiza.
Enye yezinzuzo ezibalulekile ze-MOCA indima yayo njenge-ejenti evuvukalayo yerabha eyenziwe nge-polyurethane.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 ehamba phambili yokuxhumanisa i-polyurethane coatings nama-adhesives.Ikhuthaza ukuhlangana kwamakhemikhali phakathi kwama-molecule e-polymer, okuholela ekuhlanganisweni nama-adhesives abonisa ukusebenza okuphezulu.Noma ngabe okokunamathela okuvikelayo noma okunamathelayo kwesakhiwo, i-MOCA inikeza amandla adingekayo nokuzinza.
Ngokungeziwe ekusebenziseni kwayo ku-raber nezingubo zokumboza, i-MOCA ingase isetshenziselwe ukwelapha ama-epoxy resins.Ngokungeza amanani amancane e-MOCA, i-epoxy resin ingaba nokusabela okuxhumanisayo, okuholela ekuthuthukisweni kwezakhiwo zemishini nezokushisa.Lokhu kwenza i-MOCA ibe yithuluzi elibalulekile lezimboni ezithembele kuma-epoxy resins ngemikhiqizo yazo nezinhlelo zokusebenza.
Ngaphezu kwalokho, kukhona uhlobo oluwuketshezi lwe-MOCA olwaziwa nge-Moka.Lokhu okuhlukile kungasetshenziswa njenge-ejenti yokwelapha i-polyurethane ekamelweni lokushisa, okwenza kube lula kakhulu ezinqubweni zokukhiqiza.Ukwengeza, i-Moka ingasebenza njenge-ejenti yokwelapha i-polyurea yokufafaza izicelo.Ukuguquguquka kwayo nokusebenziseka kalula kwenza kube ukukhetha okudumile phakathi kwabakhiqizi.
Ukupakisha nokugcina:
Ukupakishwa:50kg/DRUM
Isitoreji:kufanele kube endaweni epholile, yomile futhi ikhiphe umoya.
Ukuzinza:Ukushisisa nokushintsha kube mnyama, ukuswakama kancane.Akukho ukuhlolwa okuningiliziwe kwe-pathological e-China, futhi akuqiniseki ukuthi lo mkhiqizo unobuthi futhi uyingozi.Umshini kufanele uqiniswe ukuze unciphise ukuthintana nesikhumba futhi uhogele emgudwini wokuphefumula, futhi unciphise umonakalo emzimbeni womuntu ngangokunokwenzeka.
Isifinyezo:
Ukukufingqa, i-MOCA (4,4'-Methylene-Bis-(2-Chloroaniline)) iyi-ejenti eguquguqukayo futhi ewusizo kakhulu ephazamisayo kanye ne-crosslinking.Ububanzi bayo bezicelo embonini yenjoloba ye-polyurethane, okokunamathela, kanye ne-adhesives kuyenza ibe yintandokazi kubakhiqizi.Ngamandla ayo okuthuthukisa amandla, ukuqina, kanye nokuhlangana kwamakhemikhali, i-MOCA ngokungangabazeki idlala indima ebalulekile ekuqinisekiseni ikhwalithi nokusebenza kwemikhiqizo ehlukahlukene.
