Ngikholelwa ukuthi asijwayelene nezinkomishi zephepha, sizohileleka ekuphileni kwethu kwansuku zonke, njengokuthi: izinkomishi zamaphepha ezilahlwayo, izinkomishi ze-ayisikhilimu ze-ayisikhilimu nezinye izinkomishi zephepha, okulandelayo ukukunikeza ukubhala umlando wokuthuthukiswa kwezinkomishi zephepha;
Inqubo yokukhula komlando wenkomishi yephepha idlule ezigabeni ezine:
1.Inkomishi yephepha lekhoni
Izinkomishi zephepha eziqinile / ezigoqayo Izinkomishi zephepha zangempela ziyi-conical, zenziwe ngesandla, ziboshwe ngeglue, zihlukaniswa kalula, futhi kufanele zisetshenziswe ngokushesha ngangokunokwenzeka. Kamuva, izinkomishi zephepha eligoqiwe zazigoqwe odongeni oluseceleni ukuze kwandiswe amandla odonga oluseceleni nokuqina kwezinkomishi zephepha, kodwa kwakunzima ukuphrinta amaphethini kulezi zindawo ezigoqayo, futhi umphumela wawungalungile.
2.Coat inkomishi yephepha le-wax
Ngo-1932, kwavela izingcezu ezimbili kuphela zezinkomishi zephepha le-wax, indawo yayo ebushelelezi ingaphrintwa ngamaphethini ahlukahlukene amahle, ukuthuthukisa umphumela wokuphromotha. I-wax, ngakolunye uhlangothi, ingagwema ukuthintana ngokuqondile nephepha, futhi ingavikela ukunamathela kweglue futhi ithuthukise ukuqina kwendebe yephepha; ngakolunye uhlangothi, iphinde ikhulise ukushuba kodonga oluseceleni ukwandisa amandla enkomishi yephepha, ngaleyo ndlela kuncishiswe inani lephepha elidingekayo ekwenzeni izinkomishi zephepha eziqinile kanye nokunciphisa izindleko zokukhiqiza. Njengoba izinkomishi zephepha le-wax ziba iziqukathi zeziphuzo ezibandayo, kuthenjwa futhi ukuthi umkhumbi okahle ungathwala iziphuzo ezishisayo. Kodwa-ke, iziphuzo ezishisayo zizoncibilikisa ungqimba lwe-wax endaweni engaphakathi yenkomishi yephepha, futhi umlomo wokunamathisela uzohlukaniswa, ngakho indebe yephepha le-wax evamile ayifanele ukuthwala iziphuzo ezishisayo.
3.Inkomishi yodonga oluphindwe kabili
Ukuze kwandiswe uhla lwesicelo sezinkomishi zephepha, izinkomishi zephepha eziqondile zodonga oluphindwe kabili zethulwa emakethe ngo-1940. Izinkomishi zephepha akulula nje ukuzithwala, kodwa futhi ziwusizo ukubamba iziphuzo ezishisayo. Kamuva, umkhiqizi wagcoba i-latex kulezi zinkomishi ukuze amboze "ukunambitheka kwekhadibhodi" kwempahla yephepha, futhi aqinise ukumelana nokuvuza kwendebe yephepha. Izinkomishi ze-wax zongqimba olulodwa eziphathwe nge-latex enamathela zisetshenziswa kakhulu emishinini yokuzithengisa ukuze kubanjwe ikhofi elishisayo.
4.Faka inkomishi yephepha lepulasitiki
Ezinye izinkampani zokudla zaqala ukubeka i-polyethylene ekhadini ukwandisa umgoqo nokuvala uphawu lokupakishwa kwamaphepha. Njengoba indawo yokuncibilika ye-polyethylene iphakeme kakhulu kune-wax, uhlobo olusha lwenkomishi yephepha yesiphuzo ehlanganiswe nalesi sihloko singaba ekahle ukusetshenziselwa ukuthwala iziphuzo ezishisayo, okuxazulula inkinga yekhwalithi yomkhiqizo ethintekile ukuncibilika kwezinto zokumboza. Ngesikhathi esifanayo, upende lwe-polyethylene lubushelelezi kunomdwebo wokuqala we-wax, ukuthuthukisa ukubukeka kwendebe yephepha. Ngaphezu kwalokho, ubuchwepheshe bayo bokucubungula buye bushibhile futhi bushesha kunokusebenzisa indlela yokugqoka i-latex.
