MOCA,izwi kandi nka 4,4′-Methylenebis (2-chloroaniline), ni kristu y'urushinge rw'umweru kugeza ku muhondo woroshye ihinduka umukara iyo ishyushye. Iyi mvange ifite ubushobozi bwo kuyihinduramo imiterere kandi irashonga mu tunyangingo twa ketone na hydrocarbons zihumura neza. Ariko ikintu gitandukanya MOCA ni uburyo ikoreshwamo n'imikorere yayo.
Imiterere y'ibinyabutabire:Ibara ry'umuhondo ukeye rivangwa n'umweru, rishyushye kugeza ku mukara. Rifite hygroscopic gato. Rishobora gushonga muri ketone na hydrocarbons zihumura neza.
MOCA ikoreshwa cyane nk'ikintu gitera imbaraga mu gukora polyurethane rubber. Imiterere yayo yo guhuza ibintu ituma iba amahitamo meza yo kongera imbaraga no kuramba kw'ibikoresho bya polyurethane. Byongeye kandi, MOCA ikora nk'ikintu gitera imbaraga mu gusiga no gufunga polyurethane, itanga uburyo bwo gufata neza no gukora neza. Byongeye kandi, iki kintu gishobora gukoreshwa mu gusiga epoxy resins, bigatuma kiba ingenzi mu nganda zitandukanye.
Byongeye kandi, ubushobozi bwo gukora ibintu bitandukanye bya MOCA buri mu bwoko bwayo butandukanye. MOCA y'amazi ishobora gukoreshwa nk'umuti uvura polyurethane ku bushyuhe bw'icyumba, bigatuma yoroherwa kandi yoroha kuyikoresha. Ishobora kandi gukoreshwa nk'umuti uvura polyurea mu gutera imiti, bityo ikarushaho kongera ubushobozi bwayo bwo kuyikoresha.
Ibyiza n'uburyo bwo gukoresha:
Ku bijyanye n'urwego rw'ingufu za polyurethane n'imyambaro, gushaka umuti ukwiye wo guhuza no guhuza ni ingenzi cyane. Aha niho MOCA (4,4'-Methylene-Bis- (2-Chloroaniline)) ifata umwanya wa mbere. Kubera imiterere yayo idasanzwe n'uburyo butandukanye bwo kuyikoresha, MOCA yabaye ingenzi mu nganda zitandukanye.
MOCA izwiho kugaragara nk'icyitegererezo cy'urushinge rw'umweru kugeza ku muhondo woroshye, gihinduka umukara iyo kigejejwe ku bushyuhe. Byongeye kandi, ifite ubushobozi buke bwo gushonga kandi irashongeshwa muri ketone na hydrocarbons zihumura neza. Iyi miterere ituma iba nziza cyane yo gukoreshwa mu buryo butandukanye bwo gukora.
Imwe mu nyungu z'ingenzi za MOCA ni uruhare rwayo nk'igikoresho cyo gukurura irangi rya polyurethane. Mu guhuza iminyururu ya polymer, MOCA yongera imbaraga n'ubudahangarwa bwa ragi. Ibi bituma umusaruro wa nyuma ushobora kwihanganira imimerere mibi no kugumana ubuziranenge bwawo igihe kirekire.
Byongeye kandi, MOCA ikora nk'ikintu cyiza cyane gihuza irangi rya polyurethane n'amakori. Itera imbere isano hagati ya molekile za polymer, bigatuma habaho irangi n'amakori agaragaza imikorere myiza. Byaba ari irangi ririnda cyangwa irangi ry'imiterere, MOCA itanga imbaraga n'ubudahangarwa bikenewe.
Uretse gukoreshwa kwayo mu irangi no mu gusiga, MOCA ishobora no gukoreshwa mu gukaraba amaresini ya epoxy. Iyo wongeyeho MOCA nke, epoxy resin ishobora kugira ingaruka ku mikoranire, bigatuma habaho imiterere myiza ya mekanike n'ubushyuhe. Ibi bituma MOCA iba igikoresho cy'agaciro ku nganda zishingikiriza kuri epoxy resin mu bicuruzwa byazo no mu mikoreshereze yabyo.
Byongeye kandi, hari ubwoko bw'amazi bwa MOCA buzwi nka Moka. Ubu bwoko bushobora gukoreshwa nk'umuti uvura polyurethane ku bushyuhe bw'icyumba, bigatuma byoroha cyane mu bikorwa byo gukora. Byongeye kandi, Moka ishobora gukora nk'umuti uvura polyurea mu gutera imiti. Uburyo ikoreshwa mu buryo butandukanye no koroshya ikoreshwa ryayo bituma ikundwa cyane n'abakora.
Gupakira no kubika:
Gupfunyika:50kg/INGOMA
Ububiko:igomba kuba ikonje, yubamye kandi ihumeka.
Ituze:Gushyushya no guhinduka umukara, ubushuhe bucye. Nta kizamini kirambuye cy’indwara cyakozwe mu Bushinwa, kandi ntabwo byemezwa neza ko iki gicuruzwa gifite uburozi kandi cyangiza. Igikoresho kigomba kongerwamo imbaraga kugira ngo kigabanye uruhu no guhumeka umwuka uva mu myanya y’ubuhumekero, kandi kigabanye ingaruka mbi ku mubiri w’umuntu uko bishoboka kose.
Incamake:
Muri make, MOCA (4,4'-Methylene-Bis- (2-Chloroaniline)) ni ikintu gifite akamaro kanini kandi gihuza ibintu bitandukanye. Uburyo bwinshi ikoresha mu nganda za polyurethane rubber, coating, na kole bituma ikundwa n'abakora. Kubera ubushobozi bwayo bwo kongera imbaraga, kuramba, no gufatanya n'imiti, nta gushidikanya ko MOCA igira uruhare runini mu kwemeza ireme n'imikorere y'ibicuruzwa bitandukanye.
