III. Izinto eziphathekayo kunye nenkqubo yokuvelisa i-lining coating
I-cup lining coating ngumaleko okhuselayo okhusela ingaphakathi leekomityi zephepha le-ice cream. Iindidi ezisetyenziswa ngokuqhelekileyo zezinto zokwaleka zezi zilandelayo.
A. Uhlobo lwezinto ezisetyenziselwa ukugquma iikomityi zephepha, ezifana nepolyester, i-polyethylene, njl.
1. Polyethylene
I-polyethylene isetyenziswa ngokubanzi kwi-lining yengubo yeekomityi zephepha ngenxa yeempawu zayo ezintle zokungena kwamanzi kunye neoli, kunye neendleko zayo eziphantsi. Abo bayenza ilungele ukuveliswa kweekomityi zephepha ze-ice cream ezinkulu.
2. Ipolyester
Iingubo zePolyester zinokubonelela ngamanqanaba aphezulu okhuseleko. Ngaloo ndlela, inokuthintela ivumba, ukungena kwegrisi, kunye nokungena kweoksijini. Ke ngoko, i-polyester iqhele ukusetyenziswa kumgangatho ophezulu weekomityi zephepha eziphezulu.
3. PLA (polylactic acid)
I-PLA inokusebenza kakubi kwamanzi, kodwa inxulumene nokukhuselwa kwendalo kwaye isetyenziswa ngokubanzi kwezinye iimarike eziphezulu.
B. Yazisa inkqubo yokuvelisa, njengobuchule obukhethekileyo bokugquma kunye ne-welding
Inkqubo yokuvelisa i-lining coating kwiikomityi zephepha ngolu hlobo lulandelayo:
1. Itekhnoloji ekhethekileyo yokwaleka
Kwinkqubo yokuvelisa iikomityi zephepha, i-lining coating isetyenziswa ngokubanzi ukuqinisekisa ukuba amanzi kunye ne-oil resistant effect yeekomityi. Indlela yokuqinisekisa ukuba isambatho sisasazwa ngokulinganayo kuyo yonke ikomityi kukusebenzisa ubuchwepheshe bale mihla. Okokuqala, intlenga eyenziweyo iyabanjwa kwaye ilungiswe, ize ifakwe ngaphakathi kwikomityi yephepha.
2. Ukuwelda
Kwezinye iimeko, iingubo ezikhethekileyo zobugcisa azidingeki. Kule meko, umgca wangaphakathi wendebe yephepha unokusebenzisa ukutywinwa kobushushu (okanye i-welding) iteknoloji. Le yinkqubo yokucinezela iileya ezininzi zezinto ezahlukeneyo kunye, ukugcina umgca wangaphakathi kunye nomzimba wekomityi ngokuqinileyo kunye. Ngokubonelela ngoluhlu oluthembekileyo olukhuselayo, le nkqubo iqinisekisa ukuba indebe yephepha iqinile ukuya kwinqanaba elithile kwaye ayiyi kuvuza.
Oku ngasentla kukungeniswa kwiintlobo zezixhobo kunye neenkqubo zokuvelisa ukufakwa kwe-lining of cup cups. Izinto ezifanai-polyethylene kunye ne-polyester zifanelekile kumabakala ahlukeneyo ekomityi yephephas. Kwaye iteknoloji yokugqoka ekhethekileyo kunye neenkqubo zokuvelisa i-welding inokuqinisekisa umgangatho kunye nokusebenza kwe-line cup cup.
