III. Izinto kanye nenqubo yokukhiqiza ye-lining coating
I-Cup lining coating iyisendlalelo esivikelayo esivikela ingaphakathi lezinkomishi zephepha le-ayisikhilimu. Izinhlobo ezisetshenziswa kakhulu ze-lining material yilezi ezilandelayo.
A. Uhlobo lwento esetshenziselwa ulwelwesi lwezinkomishi zephepha, njenge-polyester, i-polyethylene, njll.
1. I-polyethylene
I-polyethylene isetshenziswa kakhulu ekunambeni kolwelwesi lwezinkomishi zephepha ngenxa yezindawo zayo ezinhle kakhulu zokungangeni kwamanzi namafutha, kanye nezindleko zayo eziphansi. Lawo ayenza ifanele ukukhiqizwa kwezinkomishi zephepha le-ayisikhilimu ezinkulu.
2. I-polyester
Izembatho ze-polyester zinganikeza amazinga aphezulu okuvikela. Ngakho, ingavimbela iphunga, ukungena kwamafutha, nokungena komoyampilo. Ngakho-ke, i-polyester ivame ukusetshenziswa ezinkomishini zephepha ezisezingeni eliphezulu.
3. I-PLA (i-polylactic acid)
I-PLA inokusebenza okungekuhle okungangeni manzi, kodwa ihlotshaniswa nokuvikelwa kwemvelo futhi isetshenziswa kabanzi kwezinye izimakethe ezisezingeni eliphezulu.
B. Yethula inqubo yokukhiqiza, efana nezindlela ezikhethekile zokuhlanganisa nokushisela
Inqubo yokukhiqiza i-lining coating yezinkomishi zephepha imi kanje:
1. Ubuchwepheshe bokugqoka obukhethekile
Enqubweni yokukhiqiza izinkomishi zephepha, ukumbozwa kwe-lining kusetshenziswa kabanzi ukuze kuqinisekiswe umphumela ongenamanzi nowoyela wezinkomishi. Indlela yokuqinisekisa ukuthi ukumboza kusakazwa ngokulinganayo kuyo yonke inkomishi ukusebenzisa ubuchwepheshe besimanje bomjovo. Okokuqala, i-sediment eyakhiwe iyabanjwa futhi ilungiswe, bese ijova ngaphakathi kwendebe yephepha.
2. Ukushisela
Kwezinye izimo, ukugqoka okukhethekile kwezobuchwepheshe akudingekile. Kulesi simo, ulwelwesi lwangaphakathi lwendebe yephepha lungasebenzisa ubuchwepheshe bokufaka uphawu lokushisa (noma ukushisela). Lena inqubo yokucindezela izendlalelo eziningi zezinto ezihlukahlukene ndawonye, ukugcina umugqa wangaphakathi nomzimba wenkomishi uhlangene. Ngokuhlinzeka ngesendlalelo sokuzivikela esithembekile, le nqubo iqinisekisa ukuthi indebe yephepha iqinile kuze kube sezingeni elithile futhi ngeke ivuze.
Okungenhla yisingeniso sezinhlobo zezinto zokwakha kanye nezinqubo zokukhiqiza ze-lining coating of paper cups. Izinto ezifanai-polyethylene ne-polyester ifanele amamaki ahlukene enkomishi yephephas. Futhi ubuchwepheshe obukhethekile bokugqoka kanye nezinqubo zokukhiqiza i-welding zingaqinisekisa ikhwalithi nokusebenza komugqa wenkomishi yephepha.
