I-MOCA,ekwaziwa ngokuba yi-4,4′-Methylenebis (2-chloroaniline), yikristale yenaliti emhlophe ukuya kwephuzi ekhanyayo ejika ibe mnyama xa ishushu. Le khompawundi iguquguqukayo ithambile kancinci kwaye iyanyibilika kwiiketones kunye neehydrocarbons ezinuka kamnandi. Kodwa into eyahlula iMOCA luluhlu lwezicelo zayo kunye neempawu zemveliso.
Iimpawu zekhemikhali:Ikristale yenaliti evulekileyo emhlophe ukuya kwephuzi ekhanyayo, eshushu ukuya kumnyama. Ithambile kancinci. Inyibilika kwii-ketones nakwii-hydrocarbons ezinuka kamnandi.
I-MOCA isetyenziswa kakhulu njenge-agent ye-vulcanizing kwirabha ye-polyurethane etyhidiweyo. Iimpawu zayo zokudibanisa ziyenza ibe lukhetho oluhle kakhulu lokuphucula amandla kunye nokuqina kwezinto zerabha. Ukongeza, i-MOCA isebenza njenge-agent ye-crosslinking kwiingubo ze-polyurethane kunye nezincamathelisi, inika ukunamathela okuphuculweyo kunye nokusebenza. Ngaphezu koko, le compound ingasetyenziselwa ukunyanga ii-epoxy resins, nto leyo eyenza ukuba ibe yinxalenye ebalulekileyo kumashishini ahlukeneyo.
Ngaphezu koko, ubuchule be-MOCA bufikelela kwiindlela zayo ezahlukeneyo. I-MOCA engamanzi ingasetyenziswa njenge-arhente yokupholisa i-polyurethane kubushushu begumbi, nto leyo enika lula kwaye iguquguqukayo xa isetyenziswa. Ingasetyenziswa njenge-arhente yokupholisa i-polyurea yokutshiza, nto leyo eyandisa ngakumbi indlela esebenziseka ngayo.
Iingenelo kunye nezicelo：
Xa kufikwa kwicandelo lerabha kunye neengubo ze-polyurethane, ukufumana i-agent efanelekileyo yokudibanisa kunye nokudibanisa kubalulekile. Kulapho i-MOCA (4,4'-Methylene-Bis-(2-Chloroaniline)) ithatha khona indawo ephambili. Ngeempawu zayo ezibalaseleyo kunye noluhlu olubanzi lwezicelo, i-MOCA ibe yinto ephambili kumashishini ahlukeneyo.
I-MOCA yaziwa ngokubonakala kwayo njengekristale yenaliti emhlophe ukuya kwephuzi ekhanyayo, ejika ibe mnyama xa ibekwe kubushushu. Ukongeza, ineempawu ezincinci ze-hygroscopic kwaye iyanyibilika kwii-ketones kunye nee-hydrocarbons ezinuka kamnandi. Ezi mpawu ziyenza ibe yeyona ifanelekileyo yokusetyenziswa kwiinkqubo ezahlukeneyo zokuvelisa.
Enye yeenzuzo eziphambili ze-MOCA yindima yayo njenge-ejenti yokuxuba irabha ye-polyurethane eyenziwe ngentsimbi. Ngokudibanisa imixokelelwane ye-polymer, i-MOCA yongeza amandla kunye nokuqina kwerabha. Oku kuqinisekisa ukuba imveliso yokugqibela inokumelana neemeko ezinzima kwaye igcine ukuthembeka kwayo ixesha elide.
Ngaphezu koko, i-MOCA isebenza njengearhente ebalaseleyo yokudibanisa izinto zokugquma kunye nezincamathelisi ze-polyurethane. Ikhuthaza ukubopha kweekhemikhali phakathi kweemolekyuli ze-polymer, nto leyo ebangela ukuba kubekho izinto zokugquma kunye nezincamathelisi ezibonisa ukusebenza okuphezulu. Nokuba zezogquma ezikhuselayo okanye ezincamathelisiyo zesakhiwo, i-MOCA inika amandla kunye nozinzo olufunekayo.
Ukongeza kwizicelo zayo zerabha kunye neengubo, iMOCA ingasetyenziselwa ukunyanga ii-epoxy resins. Ngokongeza inani elincinci leMOCA, i-epoxy resin ingenza i-crosslinking reaction, nto leyo ekhokelela ekuphuculweni kweempawu zoomatshini kunye nobushushu. Oku kwenza iMOCA ibe sisixhobo esibalulekileyo kumashishini axhomekeke kwii-epoxy resins kwiimveliso zawo kunye nokusetyenziswa kwazo.
Ngaphezu koko, kukho uhlobo lwe-MOCA oluyilwelo olwaziwa ngokuba yiMoka. Olu hlobo lungasetyenziswa njenge-arhente yokupholisa i-polyurethane kubushushu begumbi, nto leyo eyenza kube lula kakhulu kwiinkqubo zemveliso. Ukongeza, iMoka ingasebenza njenge-arhente yokupholisa i-polyurea xa kutshizwa. Ukuguquguquka kwayo kunye nokulula kokusetyenziswa kwayo kwenza ukuba ibe lukhetho oludumileyo phakathi kwabavelisi.
Ukupakishwa kunye nokugcinwa：
Ukupakisha:50kg/DRUM
Indawo yokugcina izinto：kufuneka ipholile, yome kwaye ingenise umoya.
Uzinzo:Ukufudumeza nokujika kube mnyama, ukufuma kancinci. Akukho vavanyo lwezifo oluneenkcukacha olwenziweyo eTshayina, kwaye akuqinisekanga ukuba le mveliso inobungozi kwaye iyingozi. Isixhobo kufuneka siqiniswe ukuze kuncitshiswe ukudibana nolusu kunye nokuphefumla kwindlela yokuphefumla, kwaye kuncitshiswe umonakalo emzimbeni womntu kangangoko kunokwenzeka.
Isishwankathelo：
Ukushwankathela, i-MOCA (4,4'-Methylene-Bis-(2-Chloroaniline)) yiarhente eguquguqukayo kakhulu nexabisekileyo yokudibanisa nokudibanisa. Uluhlu olubanzi lwezicelo zayo kushishino lwerabha ye-polyurethane, iingubo, kunye neeglue luyenza ibe lukhetho olukhethwa ngabavelisi. Ngenxa yokukwazi kwayo ukomeleza amandla, ukuqina, kunye nokubopha ngamakhemikhali, i-MOCA ngokungathandabuzekiyo idlala indima ebalulekileyo ekuqinisekiseni umgangatho kunye nokusebenza kweemveliso ezahlukeneyo.
