Wonke umuntu uyazi ukuthi umshini wenkomishi yephepha uwuhlobo lokukhiqiza indebe yephepha, enezici zokusebenza kahle kakhulu nokubumba okuhle, okungahlangabezana kahle nezidingo zomphakathi.Uyazi-ke ukuthi izinkomishi zephepha ezifakwe wax zaqala nini ukukhiqizwa?Yiziphi izici zomshini wokwenza izinkomishi?Okulandelayo ukuhlukaniswa, izinto zokukhiqiza kanye nezici zemishini yenkomishi yephepha evela kubakhiqizi bemishini yenkomishi yephepha yaseHongxin.Ukuhlukaniswa kwezinkomishi zephepha ezikhiqizwa nguumshini wenkomishi yephepha:
1. Izinkomishi zephepha ezenziwe nge-wax Ngo-1932, isethi enezicucu ezimbili zezinkomishi zephepha ezikhandisiwe, ubuso bazo obubushelelezi obungaphrintwa ngamaphethini ahlukahlukene amahle, zingathuthukisa umphumela wokukhangisa.Ngakolunye uhlangothi, i-waxing yenkomishi yephepha ingagwema ukuthintana okuqondile phakathi kwesiphuzo nephepha, ivikele ukunamathela kweglue, futhi ithuthukise ukuqina kwendebe yephepha;ngakolunye uhlangothi, iphinde ikhulise ukushuba kodonga oluseceleni, okuthuthukisa kakhulu amandla enkomishi yephepha futhi kunciphise isikhathi sokukhiqiza.Inani lephepha elidingekayo ezinkomishini eziqinile, ngaleyo ndlela kuncishiswe izindleko zokukhiqiza.Njengoba izinkomishi zephepha le-wax ziba iziqukathi zesiphuzo esibandayo, abantu bafuna isitsha esikahle sesiphuzo esishisayo.Kodwa iziphuzo ezishisayo zizoncibilikisa ungqimba lwe-wax endaweni engaphakathi yendebe, futhi isibopho sizohlukana.Ngakho-ke, izinkomishi zephepha le-wax ezijwayelekile azifanelekile ukubamba iziphuzo ezishisayo.
2. Ukuze kwandiswe ububanzi bokusetshenziswa kwezinkomishi zephepha, izinkomishi zephepha ezinengqimba eqondile yodonga oluqondile zaqalwa ngo-1940. Le nkomishi yephepha akulula nje ukuyiphatha, kodwa ingasetshenziswa nokubamba iziphuzo ezishisayo.Kusukela lapho, abakhiqizi baye bagcoba izinkomishi nge-latex ukuze bavale “iphunga lekhadibhodi” lephepha futhi bathuthukise izici zenkomishi zokungavuzi.Izinkomishi ze-wax zongqimba olulodwa ezine-latex enamathela zisetshenziswa kakhulu ukubamba ikhofi elishisayo emishinini yokuthengisa.
3. Izinkomishi zephepha ezimbozwe ngepulasitikiEzinye izinkampani zokudla seziqalile ukugqoka amakhadibhodi nge-polyethylene ukukhulisa umgoqo kanye nokuqina komoya kokupakishwa kwephepha.Njengoba iphuzu lokuncibilika kwe-polyethylene liphakeme kakhulu kune-wax, izinkomishi zephepha eziboshwe nge-polyethylene zingasetshenziswa ukubamba iziphuzo ezishisayo, ezingaxazulula inkinga yokuthi ukuncibilika kwezinto zokugqoka kuthinta ikhwalithi yomkhiqizo.Ngesikhathi esifanayo, i-polyethylene yokugqoka ilula kune-wax yokuqala yokugqoka, ukuthuthukisa ukubukeka kwezinkomishi zephepha.Ngaphezu kwalokho, ubuchwepheshe bayo bokucubungula ishibhile futhi bushesha kunezindlela zisebenzisa i-latex coatings.
