MOCA,ekwaziwa ngokuba yi-4,4′-Methylenebis(2-chloroaniline), yikristale enaliti emhlophe ukuya emthubi ejika ibemnyama xa ishushu.Le khompawundi iguquguqukayo i-hygroscopic kancinane kwaye iyanyibilika kwiiketoni kunye neehydrocarbons ezinevumba elimnandi.Kodwa yintoni eyahlula i-MOCA luluhlu lwayo lwezicelo kunye neempawu zemveliso.
Iimpawu zemichiza:emhlophe ukuya kokukhanya tyheli enaliti ejiyileyo eyikristale, ifudunyezwe ibemnyama.I-hygroscopic kancinci.Inyibilika kwiiketoni kunye neehydrocarbons ezinevumba elimnandi.
I-MOCA isetyenziswa kakhulu njenge-agent ebangela irabha eyenziwe nge-polyurethane.Iimpawu zayo ezinqamlezileyo zenza kube lukhetho oluhle kakhulu lokuphucula amandla kunye nokuqina kwezinto zerabha.Ukongezelela, i-MOCA isebenza njenge-agent edibanisayo kwiingubo ze-polyurethane kunye ne-adhesives, enikezela ukunamathela kunye nokusebenza okuphuculweyo.Ngaphaya koko, le khompawundi ingasetyenziselwa ukunyanga iiresin ze-epoxy, iyenza ibe yinxalenye ebalulekileyo kumashishini ahlukeneyo.
Ngaphezu koko, ukuguquguquka kwe-MOCA kufikelela kwiintlobo zayo ezahlukeneyo.Ulwelo lwe-MOCA lunokuqeshwa njenge-arhente yokunyanga i-polyurethane kwiqondo lobushushu begumbi, ibonelela ngokulula kunye nokuguquguquka kwisicelo.Isenokusetyenziswa njenge-arhente yokunyanga i-polyurea yokutshiza, ukwandisa ngakumbi uluhlu lwayo lokusebenziseka.
Izinto eziluncedo kunye nezicelo:
Xa kuziwa kwintsimi yerabha ye-polyurethane kunye neengubo, ukufumana i-vulcanizing efanelekileyo kunye ne-agent edibeneyo ibalulekile.Kulapho i-MOCA (4,4'-Methylene-Bis-(2-Chloroaniline)) ithatha indawo ephakathi.Ngeempawu zayo ezikhethekileyo kunye noluhlu olubanzi lwezicelo, i-MOCA ibe yeyona nto iphambili kumashishini ahlukeneyo.
I-MOCA yaziwa ngokubonakala kwayo njengomhlophe ukuya kwikristale yenaliti etyheli, ejika ibe mnyama xa ibonakaliswe kubushushu.Ukongeza, ineempawu ezincinci zehygroscopic kwaye iyanyibilika kwiiketoni kunye neehydrocarbons ezinuka kamnandi.Ezi mpawu zenza ukuba ibe ngumgqatswa ofanelekileyo wokusetyenziswa kwiinkqubo ezahlukeneyo zokuvelisa.
Enye yeenzuzo eziphambili ze-MOCA yindima yayo njenge-agent ebangela i-vulcanizing irabha eyenziwe nge-polyurethane.Ngokudibanisa amakhonkco e-polymer, i-MOCA iphakamisa amandla kunye nokuqina kwerabha.Oku kuqinisekisa ukuba imveliso yokugqibela inokumelana neemeko ezinzima kwaye igcine ingqibelelo yayo ixesha elide.
Ngaphaya koko, i-MOCA isebenza njengeyona arhente igqwesileyo yokudibanisa i-polyurethane kunye ne-adhesives.Ikhuthaza ukuhlangana kweekhemikhali phakathi kweemolekyuli zepolymer, okukhokelela kwiingubo kunye nokunamathiswa okubonisa ukusebenza okuphezulu.Nokuba yeyokugquma kokukhusela okanye ukuncamathelisa kolwakhiwo, i-MOCA ibonelela ngamandla ayimfuneko kunye nokuzinza.
Ukongeza kwizicelo zayo kwi-rubber kunye neengubo, i-MOCA ingasetyenziselwa ukunyanga i-epoxy resins.Ngokongeza ixabiso elincinci le-MOCA, i-epoxy resin inokuthi iqhube i-crosslinking reaction, ekhokelela ekuphuculweni kwezakhiwo zomatshini kunye ne-thermal.Oku kwenza i-MOCA ibe sisixhobo esixabisekileyo kumashishini axhomekeke kwi-epoxy resins kwiimveliso kunye nokusetyenziswa kwazo.
Ngaphaya koko, kukho ulwelo lwe-MOCA eyaziwa ngokuba yiMoka.Olu lwahlukano lunokusetyenziswa njengearhente yokunyanga i-polyurethane kwiqondo lobushushu begumbi, nto leyo eyenza kube lula kakhulu kwiinkqubo zemveliso.Ukongeza, i-Moka inokusebenza njenge-arhente yokunyanga i-polyurea yokutshiza izicelo.Ukuguquguquka kwayo kunye nokulula kokusetyenziswa kwenza kube lukhetho oludumileyo phakathi kwabavelisi.
Ukupakishwa kunye nokugcinwa:
Ukupakishwa:50kg/DRUM
Ugcino:kufuneka ipholile, yome kwaye ikhuphe umoya.
Uzinzo:Ukufudumala kunye nokujika kube mnyama, ukufuma okuncinci.Akukho luvavanyo luneenkcukacha lwe-pathological e-China, kwaye akuqinisekanga ukuba le mveliso inetyhefu kwaye iyingozi.Isixhobo kufuneka siqiniswe ukunciphisa ukudibanisa nolusu kunye nokuphefumla kwindlela yokuphefumula, kunye nokunciphisa umonakalo kumzimba womntu kangangoko kunokwenzeka.
Isishwankathelo:
Ukuyishwankathela, i-MOCA (4,4'-Methylene-Bis-(2-Chloroaniline)) iyinto eninzi kakhulu kwaye ixabiseke kakhulu i-vulcanizing kunye ne-agent edibanisayo.Uluhlu lwayo olubanzi lwezicelo kwirabha ye-polyurethane, i-coatings, kunye ne-adhesive industry iyenza ibe lukhetho lokukhetha kubenzi.Ngokukwazi kwayo ukomeleza amandla, ukuqina, kunye nokudibanisa imichiza, i-MOCA ngokungathandabuzekiyo idlala indima ebalulekileyo ekuqinisekiseni umgangatho kunye nokusebenza kweemveliso ezahlukeneyo.
