Ukubunjwa kwe-Carbide kwaziwa ngokuthi "izinsika ezintathu" zobuchwepheshe bokubumba umkhiqizo wepulasitiki

Isikhunta seCarbideEmkhakheni wokucubungula impahla ye-polymer, isikhunta esisetshenziselwa ukubumba imikhiqizo yesikhunta se-carbide esine-cemented sibizwa ngokuthi isikhunta esakha ipulasitiki, noma isikhunta sepulasitiki ngamafuphi. Ekukhiqizeni imikhiqizo yepulasitiki yesimanje, ubuchwepheshe bokucubungula okunengqondo, imishini yokusebenza kahle kakhulu kanye nezibunjwa ezithuthukisiwe ziyaziwa ngokuthi "izinsika ezintathu" zobuchwepheshe bokubumba umkhiqizo wepulasitiki. Ikakhulukazi, isikhunta sepulasitiki sidlala indima engenakuthathelwa indawo ekufezeni izidingo zobuchwepheshe bokucubungula izingxenye zepulasitiki, izidingo zokusetshenziswa kwezingxenye zepulasitiki, kanye nezidingo zokubukeka kwezingxenye zepulasitiki. Imishini esebenza ngokuzenzakalelayo esebenza kahle kakhulu ingakwazi ukusebenza ngendlela efanele kuphela uma ifakwe isikhunta esikwazi ukukhiqiza ngokuzenzakalelayo.

1. Isikhunta sokujova isikhunta se-Carbide sisebenzisa isikulufu noma ipiston yomshini womjovo ukujova ipulasitiki eyenziwe ngepulasitiki nencibilikisiwe emgqonyeni wesikhunta ngembobo nesistimu yokuthela, futhi isikhunta esisetshenziselwa ukuqinisa sibizwa ngokuthi isikhunta somjovo. Isikhunta sokujova sisetshenziselwa ikakhulukazi ukubumba imikhiqizo ye-thermoplastic. Eminyakeni yamuva, ziya ngokuya zisetshenziselwa ukubumba imikhiqizo yepulasitiki ye-thermosetting. Lolu uhlobo lwesikhunta sepulasitiki esisetshenziswa kabanzi, ingxenye enkulu, kanye nobuchwepheshe obuvuthiwe. Ngenxa yezinto ezihlukene noma izingxenye zepulasitiki noma izinqubo zokubumba, kukhona isikhunta se-thermosetting umjovo wepulasitiki, isikhunta sesakhiwo somjovo wegwebu, isikhunta sokubumba umjovo wokusabela, kanye nezibunjwa zokujova ezisizwa ngegesi.

2. Isikhunta sokucindezela isikhunta se-Carbide sisebenzisa ukucindezela nokushisa ukuze kuncibilike futhi kuqiniswe ipulasitiki ebekwe ngokuqondile emgodini, okubizwa ngokuthi isikhunta sokucindezela. Izibunjwa zokucindezela zisetshenziselwa ikakhulukazi ukubumba imikhiqizo yepulasitiki ye-thermosetting, kodwa futhi ingasetshenziselwa ukubumba imikhiqizo yepulasitiki ye-thermoplastic.

3. Isikhunta somjovo sisebenzisa i-plunger ukuvumela ipulasitiki eyenziwe ngepulasitiki nencibilikile endaweni yokudla ifakwe emgodini ovaliwe ngokusebenzisa uhlelo lokuthela, futhi isikhunta esisetshenziselwa ukuqiniswa sibizwa ngokuthi isikhunta somjovo. Isikhunta somjovo sisetshenziswa kakhulu ekubumbeni imikhiqizo yepulasitiki ye-thermosetting.
