Ukukhethwa kwengubo yangaphakathi yeetini ze-tinplate (oko kukuthi, iitini zentsimbi ezigqunywe nge-tin) kudla ngokuxhomekeka kuhlobo lwengubo, ngenjongo yokuphucula ukumelana nokugqwala kwetini, ukukhusela umgangatho wemveliso, kunye nokuthintela iimpembelelo ezingafunekiyo phakathi kwesinyithi kunye nomxholo. Apha ngezantsi kukho umxholo oqhelekileyo kunye nokukhetha okufanayo kwengubo yangaphakathi:
1. Iziselo (umz., iziselo ezibandayo, iijusi, njl.njl.)
Kwiziselo ezinezithako ze-asidi (ezifana nejusi yelamuni, ijusi yeorenji, njl.njl.), ugqubuthelo lwangaphakathi ludla ngokuba lugqubuthelo lwe-epoxy resin okanye ugqubuthelo lwe-phenolic resin, njengoko ezi gqubuthelo zibonelela ngokumelana ne-asidi egqwesileyo, zithintela ukusabela phakathi komxholo kunye nesinyithi kwaye ziphephe iincasa ezingezizo okanye ungcoliseko. Kwiziselo ezingezizo ze-asidi, ugqubuthelo lwe-polyester olulula (olufana nefilimu ye-polyester) ludla ngokwanela.
2. Ibhiya nezinye iziselo ezinxilisayo
Iziselo ezinxilisayo zingcolisa ngakumbi iintsimbi, ngoko ke kusetyenziswa ii-epoxy resin okanye ii-polyester coatings. Ezi coatings zihlukanisa ngempumelelo utywala kwi-steel can, zithintela ukugqwala kunye notshintsho lwencasa. Ukongeza, ezinye coatings zibonelela ngokhuseleko lwe-oxidation kunye nokhuseleko olukhanyayo ukuthintela incasa yesinyithi ukuba ingangeni kwisiselo.
3. Iimveliso zokutya (umz., iisuphu, imifuno, inyama, njl.njl.)
Kwimveliso yokutya enamafutha amaninzi okanye ene-asidi ephezulu, ukukhetha indlela yokugcoba kubaluleke kakhulu. Iingubo zangaphakathi eziqhelekileyo ziquka i-epoxy resin, ingakumbi iingubo ze-epoxy-phenolic resin composite, ezinganiki nje kuphela ukumelana ne-asidi kodwa zinokumelana namaqondo obushushu aphezulu kunye noxinzelelo, ukuqinisekisa ukugcinwa kwexesha elide kunye nobomi beshelufu bokutya.
4. Iimveliso zobisi (umz., ubisi, iimveliso zobisi, njl.njl.)
Iimveliso zobisi zifuna uboya obusebenza kakuhle, ingakumbi ukuthintela ukusebenzisana phakathi koboya kunye neeproteni kunye namafutha kubisi. Uboya obusetyenziswa yipolyester buhlala busetyenziswa kuba bunika ukumelana okuhle kwe-asidi, ukumelana ne-oxidation, kunye nozinzo, bugcina ngokufanelekileyo incasa yeemveliso zobisi kwaye buqinisekisa ukugcinwa kwazo ixesha elide ngaphandle kongcoliseko.
5. Iioyile (umz., iioyile ezityiwayo, iioyile zokuthambisa, njl.njl.)
Kwiimveliso zeoyile, ugqubuthelo lwangaphakathi kufuneka lugxile ekuthinteleni ioyile ukuba ingadibani nesinyithi, kuthintelwe iincasa ezingezizo okanye ungcoliseko. Iingubo ze-epoxy resin okanye ze-polyester zisetyenziswa rhoqo, njengoko ezi ngubo zikwazi ukwahlula ioyile ngaphakathi kwesinyithi se-can, ziqinisekisa uzinzo kunye nokhuseleko lwemveliso yeoyile.
6. Iikhemikhali okanye iipeyinti
Kwiimveliso ezingezizo zokutya ezifana neekhemikhali okanye iipeyinti, ulwelo lwangaphakathi kufuneka lunike ukumelana okunamandla nokugqwala, ukumelana neekhemikhali, kunye nokumelana nobushushu obuphezulu. Ulwelo lwe-epoxy resin okanye ulwelo lwe-polyolefin olunekhlorini ludla ngokukhethwa, njengoko luthintela ngempumelelo ukusabela kweekhemikhali kwaye lukhusela umxholo.
Isishwankathelo seMisebenzi yokuGcoba ngaphakathi:
• Ukumelana nokugqwala: Kuthintela ukusabela phakathi kwezinto eziqulethwe kwisinyithi, nto leyo eyandisa ixesha lokugcinwa kwaso.
• Ukuthintela ungcoliseko: Kuthintela ukutsalwa kweencasa zesinyithi okanye ezinye iincasa ezingafakwanga kwincasa, okuqinisekisa umgangatho wencasa.
• Iimpawu zokutywina: Ziphucula ukusebenza kokutywina kwetini, ziqinisekisa ukuba umxholo awuchatshazelwa zizinto zangaphandle.
• Ukumelana ne-oxidation: Kunciphisa ukuvezwa komxholo kwi-oksijini, oku kubambezela iinkqubo ze-oxidation.
• Ukumelana nobushushu: Kubaluleke ngakumbi kwiimveliso ezilungiswa ngobushushu obuphezulu (umz., ukubulala iintsholongwane ekutyeni).
Ukukhetha i-inside coating efanelekileyo kunokuqinisekisa ngokufanelekileyo ukhuseleko kunye nomgangatho wemveliso epakishiweyo ngelixa ihlangabezana nemigangatho yokhuseleko lokutya kunye neemfuno zokusingqongileyo.
