III. Ukuklama kwesakhiwo sezinkomishi zephepha
A. Ubuchwepheshe bokufaka ingaphakathi lezinkomishi zephepha
1. Ukuthuthukiswa kwezakhiwo zokuvimbela amanzi kanye ne-insulation
Ubuchwepheshe bokugcoba kwangaphakathi bungomunye wemiklamo eyinhloko yezinkomishi zephepha, ezingathuthukisa ukusebenza kokufakwa kwamanzi nokushisayo kwezinkomishi.
Ekukhiqizeni inkomishi yephepha yendabuko, ungqimba lwe-polyethylene (PE) lokumboza luvame ukusetshenziswa ngaphakathi kwendebe yephepha. Lokhu kunamathela kunokusebenza okuhle okungangeni manzi. Ingavimbela ngokuphumelelayo iziphuzo ukuthi zingangeni ngaphakathi kwendebe yephepha. Futhi kungavimbelainkomishi yephephakusuka ekukhubazekeni nasekuphuleni. Ngesikhathi esifanayo, ukugqoka kwe-PE nakho kungahlinzeka ngomphumela othile wokufakelwa. Ingavimbela abasebenzisi ukuthi bangezwa ukushisa okukhulu uma bephethe izinkomishi.
Ngokungeziwe ekuhlanganiseni kwe-PE, kukhona nezinye izinto ezintsha zokugqoka ezisetshenziswa kakhulu ezinkomishini zephepha. Ngokwesibonelo, polyvinyl utshwala (PVA) enamathela. Inokumelana kahle namanzi kanye nokumelana nokuvuza. Ngakho-ke, ingakwazi ukugcina ingaphakathi lenkomishi yephepha lomile. Ngaphezu kwalokho, i-polyester amide (PA) enamathelayo inokucaca okuphezulu nokusebenza kokuvala ukushisa. Ingathuthukisa ikhwalithi yokubukeka nokusebenza kokuvala ukushisa kwezinkomishi zephepha.
2. Isiqinisekiso Sokuphepha Kokudla
Njengesitsha esisetshenziselwa ukubamba ukudla neziphuzo, izinto zokumboza zangaphakathi zezinkomishi zephepha kufanele zihambisane nezindinganiso zokuphepha kokudla. Lokhu kuqinisekisa ukuthi abantu bangayisebenzisa ngokuphepha.
I-internal coating material idinga ukuthola isitifiketi esifanele sokuphepha kokudla. Okufana nesitifiketi se-FDA (Food and Drug Administration), isitifiketi sempahla yokuxhumana nokudla kwe-EU, njll. Lezi zitifiketi ziqinisekisa ukuthi okokumboza ngaphakathi kwenkomishi yephepha akubangeli ukungcoliswa kokudla neziphuzo. Futhi kuyadingeka ukuqinisekisa ukuthi azikhiphi izinto eziyingozi, okuqinisekisa impilo nokuphepha kwabasebenzisi.
B. Umklamo okhethekile wesakhiwo sezinkomishi zephepha
1. Idizayini yokuqinisa engezansi
Idizayini yokuqinisa engezansi ye-inkomishi yephephaiwukuthuthukisa amandla esakhiwo sendebe yephepha. Lokhu kungavimbela inkomishi yephepha ukuthi ingawi ngesikhathi sokugcwalisa nokusebenzisa. Kunemiklamo emibili evamile yokuqinisa phansi: iphansi eligoqiwe kanye nephansi eliqinisiwe.
Ukugoqa phansi kuwumklamo owenziwe kusetshenziswa inqubo ethile yokugoqa phansi kwenkomishi yephepha. Izendlalelo eziningi zephepha zikhiyelwe ndawonye ukuze zakhe isakhiwo esingaphansi esiqinile. Lokhu kuvumela inkomishi yephepha ukuthi imelane nenani elithile lamandla adonsela phansi nokucindezela.
Iphansi eliqinisiwe liwumklamo osebenzisa ukwakheka okukhethekile noma izinto ezingaphansi kwendebe yephepha ukuze kwandiswe amandla esakhiwo. Isibonelo, ukwandisa ukushuba phansi kwendebe yephepha noma ukusebenzisa impahla yephepha eqinile. Lezi zingathuthukisa ngokuphumelelayo amandla aphansi enkomishi yephepha futhi zithuthukise ukumelana kwayo nokucindezela.
2. Ukusetshenziswa komphumela wesitsha
Izinkomishi zamaphepha zivame ukupakishwa ezitsheni ngesikhathi sokuthutha nokugcinwa. Lokhu kungonga isikhala futhi kuthuthukise ukusebenza kahle. Ngakho-ke, ezinye imiklamo yesakhiwo ekhethekile isetshenziswa ezinkomishini zephepha. Lokhu kungazuza umphumela ongcono wesiqukathi.
Isibonelo, ukuklama kwekhaliber yenkomishi yephepha kungenza iphansi lenkomishi livale phezulu kwendebe yephepha elandelayo. Lokhu kwenza kube lula ukuthi izinkomishi zephepha zilingane futhi zonge isikhala. Ngaphezu kwalokho, ukuklama okunengqondo kwesilinganiso sobude nobubanzi bezinkomishi zephepha nakho kungathuthukisa ukuzinza kokupakishwa kwenkomishi yephepha. Lokhu kungagwema izimo ezingazinzile phakathi nenqubo yokunqwabelanisa.
Ubuchwepheshe bokugqoka obungaphakathi kanye nomklamo okhethekile wesakhiwo wezinkomishi zephepha kungathuthukisa ukusebenza nokusebenza kwazo. Ngokusungula izinto ezintsha kanye nokwenza ngcono, izinkomishi zephepha zingahlangabezana kangcono nezidingo zabantu zezinsiza zokuxhumana Zokudla. Ngaphezu kwalokho, inganikeza ulwazi lomsebenzisi oluphephile, olulula, futhi oluhambisana nemvelo.
