Moca,Kwabizwa ngokuba yi-4,4''-methynenebis (2-Chiroilililine), umhlophe ukuqaqanjelwa kwenaliti egudileyo yenaliti eguqukayo emnyama xa ifudumele. Eli candelo liguquguqukayo liyinto encinci i-hygroscopic kwaye inyibilikisi eKetones kunye ne-hermatic hydrocarbons. Kodwa yintoni le iseti yeMoca yodwa luluhlu lwayo lwezicelo kunye neempawu zemveliso.
Iipropathi zeekhemikhali:mhlophe ukuqaqanjelwa i-crystal yenaliti, eshushu kakhulu. I-hygroscopic kancinci. Inyibilikisi eKetones kunye ne-hydrocarbles.
I-MOCA isetyenziswa ikakhulu njengearhente yokungaqhelekanga kwirakhi yePolyurthane. Iipropathi zayo ezinqamlezileyo zenza ukuba kuthathe ukhetho oluhle lokuphucula amandla kunye nokuqina kwezixhobo zerabha. Ukongeza, iMoca isebenza njenge-arhente enqamlezileyo ye-Polyredthane Coayings kunye neencwadana, ukuhambisa ukuphuculwa komthendeleko kunye nokusebenza. Ngapha koko, le nqaku inokusetyenziselwa ukunyanga i-Epoxy Reward, iyenza ibe licandelo elixabisekileyo kumashishini ahlukeneyo.
Ngaphezu koko, indlela yokusebenza kaMoca idlulela kwiindlela zayo ezahlukeneyo. I-MOCA ye-icoca inokuqeshwa njenge-Polyredthane Argemethane yokunyanga kubushushu begumbi, inika lula kunye nokuguquguquka kwesicelo. Ingasetyenziselwa njenge-Amerusa yonyango lwePolyurea yokutshiza, ukwandisa ngakumbi ukushumayela kwawo.
Izibonelelo kunye nokuSebenza:
Xa kufikwa kumhlaba werali yePolyurethane irabha kunye nengubo, ukufumana i-velcaning efanelekileyo kunye ne-arhente enqamlezileyo ibalulekile. Kulapho moca (4,4'-methylene-bis- (2-Chis-Chisianililine)) ithatha inqanaba leziko. Ngeepropathi zayo ezikhethekileyo kunye noluhlu olubanzi lwezicelo, iMoca iba sisibetho kumashishini ahlukeneyo.
I-MOCA yaziwa ngokuba imhlophe njengemhlophe ukuqaqanjelwa inaliti ye-Crystal egudileyo, ejika imnyama xa ityhilwe kubushushu. Ukongeza, inayo i-hygroscopic ye-hygroscopic kwaye inyibilika eKetones kunye ne-chadrocarbles. Ezi mpawu zenza ukuba ibe ngumgqatswa ofanelekileyo wokusetyenziswa kwiinkqubo ezahlukeneyo zokwenza imveliso.
Enye yezibonelelo eziphambili zeMoca yindima yayo njenge-arhente yokungaqhelekanga ye-polyurrethane irabha. Ngokuncoma imixokelelwane yePolymer, iMoca yandisa amandla kunye nokuqina kwerabha. Oku kuqinisekisa ukuba imveliso yokugqibela inokumelana neemeko ezinzima kwaye igcine ingqibelelo yexesha elide.
Ngaphaya koko, iMoca isebenza njenge-arhente egqwesileyo enqamlezileyo ye-Polyredthane kunye neencwadana. Ikhuthaza ukubambelela kwamachiza phakathi kweemolekyuli zePolymer, ezikhokelela kwi-cares kunye nee-cohethees ezibonisa ukusebenza okuphezulu. Nokuba kungenxa yamangalali okhuselayo okanye izibhengezo zesakhiwo, iMoca ibonelela ngamandla ayimfuneko kunye nozinzo.
Ukongeza kwizicelo zayo kwirabha kunye nengubo, iMoca inokusetyenziselwa ukunyanga i-epoxy resins. Ngokongeza izixa ezincinci zeMoca, i-epoxy resin inokujonga ukuphendula, ekhokelela kwiipropathi eziphuculiweyo kunye ne-thermal. Oku kwenza ukuba i-MECA isixhobo esixabisekileyo kumashishini axhomekeke kwi-Epoxy iphinde iphinde ixhase iimveliso kunye nezicelo zawo.
Ngaphaya koko, kukho ifomu yotywala yeMoca eyaziwa ngokuba yi-Moka. Oku kwahluka kunokusetyenziswa njengearhente yepoliurethane kwiqondo lokushisa kwigumbi, kwenza kube lula kakhulu kwiinkqubo zokuvelisa. Ukongeza, i-MUKA inokusebenza njengearhente yonyango yePolyurea yokutshiza izicelo. Ukusetyenziswa kwenqanaba lokusebenza kunye nokuncipha kwendlela yokwenza ukuba kukhetho oluqhelekileyo phakathi kwabavelisi.
Ukupakisha kunye nokugcinwa:
Ukupakisha:I-50kg / idrum
Ukugcinwa:kufuneka ibekhona, yomile kwaye ingena moya.
Uzinzo:Ukufudumeza kunye nokuguqula umnyama, kancinane mkhulu. Akukho luvavanyo lwentlungu yentlungu eTshayina, kwaye aluqinisekanga ukuba le mveliso iyityhefu kunye nengozi. Esi sixhobo kufuneka somelezwe ukunciphisa unxibelelwano ngolusu kwaye singene kwiphecana lokuphefumla, kwaye linciphise ubungozi bomzimba womntu kangangoko kunokwenzeka.
Isishwankathelo:
Ukuyinceda, Moca (4,4'-bis- bis- (2-Chis-Chisililililine)) kukuphazamiseka kakhulu kwaye kungummeli onqabileyo onqabileyo kunye ne-arhente enqamlezileyo kunye ne-arhente enqamlezileyo kunye ne-arhente enqamlezileyo kunye nenkampani enqamlezileyo. Uluhlu lwayo lwezicelo kwiraliyo yePolyurrethane, i-cayings, kunye nomzi-mveliso wase-Abheshe wenza ukuba ihambe-kukhethelele kubavelisi. Ngokukwazi ukomeleza amandla, ukuqina, kunye nokugqobhoza kwamachiza, iMoca ngokungathandabuzekiyo idlala indima ebalulekileyo ekuqinisekiseni umgangatho kunye nokusebenza kweemveliso ezahlukeneyo.
