Isikulufu se-Chipboard:
1. Ukwelapha ukushisa: Kuyindlela yokushisisa insimbi emazingeni okushisa ahlukene bese usebenzisa izindlela zokupholisa ezihlukene ukuze kufezwe izinhloso ezahlukene zokushintsha izakhiwo zensimbi.Izindlela zokwelapha ezivame ukusetshenziswa kakhulu yilezi: ukucisha, ukucisha, nokuthulisa.Hlobo luni lwemiphumela ezizokhiqizwa yilezi zindlela ezintathu?
2. Ukucisha: Indlela yokwelapha ukushisa lapho insimbi ishiselwa khona ibe ngaphezu kuka-942 degrees Celsius ukuze yenze amakristalu ensimbi abe yi-austenitic state, bese icwiliswa emanzini abandayo noma emafutheni apholisayo ukuze kucime ukuze kwenziwe amakristalu ensimbi abe sesimweni se-martensitic.Le ndlela ingandisa amandla nobulukhuni bensimbi.Kunomehluko omkhulu kakhulu emandleni nobulukhuni bensimbi enelebula elifanayo ngemva kokucisha futhi ngaphandle kokucisha.
3. I-Annealing: Indlela yokwelapha ukushisa lapho insimbi iphinde ifudumale ibe yisimo esibucayi bese ipholiswa ngokwemvelo emoyeni.Le ndlela inganciphisa amandla nobulukhuni bensimbi, ithuthukise ukuguquguquka kwayo, futhi yenze kube lula ukucubungula.Ngokuvamile, insimbi izodlula kulesi sinyathelo ngaphambi kokucubungula.
4. I-Tempering: Kungakhathaliseki ukuthi ivaliwe, i-annealed noma i-press-formed, insimbi izokhiqiza ukucindezeleka kwangaphakathi, futhi ukungalingani kokucindezeleka kwangaphakathi kuzothinta isakhiwo kanye nezakhiwo zemishini yensimbi ngaphakathi, ngakho-ke inqubo yokushisa iyadingeka.Indaba igcinwa ifudumele ngokuqhubekayo ekushiseni okungaphezu kwama-700 degrees, ukucindezeleka kwayo kwangaphakathi kuyashintshwa bese kupholiswa ngokwemvelo.
