Nhọrọ nke mkpuchi dị n'ime maka mkpọ tinplate (ya bụ, ite ígwè nwere agba agba) na-adaberekarị n'ụdị ihe dị n'ime ya, na-achọ ịkwalite nguzogide corrosion nke ike ahụ, chebe àgwà ngwaahịa ahụ, ma gbochie mmeghachi omume na-adịghị mma n'etiti ígwè na ihe dị n'ime ya. . N'okpuru bụ ọdịnaya nkịtị yana nhọrọ dabara adaba nke mkpuchi ime:
1. Ihe ọṅụṅụ (dịka ọmụmaatụ, mmanya dị nro, ihe ọṅụṅụ, wdg)
Maka ihe ọṅụṅụ nwere ihe ọṅụṅụ acidic (dị ka ihe ọṅụṅụ lemon, ihe ọṅụṅụ oroma, wdg), mkpuchi dị n'ime bụ ihe mkpuchi epoxy resin ma ọ bụ mkpuchi resin phenolic, n'ihi na mkpuchi ndị a na-enye ezigbo nguzogide acid, na-egbochi mmeghachi omume n'etiti ọdịnaya na metal na izere. oyi-flavors ma ọ bụ mmetọ. Maka ihe ọṅụṅụ na-abụghị acidic, ihe mkpuchi polyester dị mfe (dị ka ihe nkiri polyester) na-ezukarị.
2. Beer na ihe ọṅụṅụ ndị ọzọ na-egbu egbu
Ihe ọṅụṅụ na-aba n'anya na-emerụ ahụ karịa ọla, ya mere a na-ejikarị epoxy resin ma ọ bụ mkpuchi polyester eme ihe. Ihe mkpuchi ndị a na-ekewapụ mmanya na-aba n'anya nke ọma site na ígwè nwere ike, na-egbochi mmebi na mgbanwe ekpomeekpo. Na mgbakwunye, ụfọdụ mkpuchi na-enye nchebe oxidation na nchebe ọkụ iji gbochie uto igwe ịbanye n'ime ihe ọṅụṅụ ahụ.
3. Ngwa nri (dịka ọmụmaatụ, ofe, akwụkwọ nri, anụ, wdg)
Maka ngwaahịa nri dị oke abụba ma ọ bụ nnukwu acid, nhọrọ nke mkpuchi dị mkpa karịsịa. Ihe mkpuchi dị n'ime a na-emekarị gụnyere epoxy resin, karịsịa epoxy-phenolic resin composite coatings, nke na-abụghị nanị na-enye nguzogide acid kama ọ pụkwara iguzogide okpomọkụ na nrụgide dị elu, na-eme ka nchekwa ogologo oge na ndụ nchekwa nke nri.
4. Ngwaahịa mmiri ara ehi (dịka ọmụmaatụ, mmiri ara ehi, ngwaahịa mmiri ara ehi, wdg)
Ngwaahịa mmiri ara ehi chọrọ mkpuchi na-arụ ọrụ dị elu, karịsịa iji zere mmekọrịta dị n'etiti mkpuchi na protein na abụba na mmiri ara ehi. A na-ejikarị mkpuchi polyester eme ihe ka ha na-enye ezigbo nguzogide acid, nguzogide oxidation, na nkwụsi ike, na-echekwa ekpomeekpo nke ngwaahịa mmiri ara ehi nke ọma ma hụ na nchekwa ha dị ogologo oge na-enweghị mmetọ.
5. Mmanụ (dịka ọmụmaatụ, mmanụ oriri, mmanu mmanu, wdg)
Maka ngwaahịa mmanụ, mkpuchi nke dị n'ime ga-elekwasị anya n'igbochi mmanụ ka ọ na-emeghachi omume na ígwè, na-ezere ihe na-esi ísì ụtọ ma ọ bụ mmetọ. A na-ejikarị mkpuchi Epoxy resin ma ọ bụ polyester eme ihe, ebe ọ bụ na mkpuchi ndị a na-ekewapụ mmanụ nke ọma n'ime ime ụlọ nke nwere ike, na-eme ka nkwụsi ike na nchekwa nke ngwaahịa mmanụ.
6. Chemicals ma ọ bụ agba
Maka ngwaahịa ndị na-abụghị nri dị ka kemịkalụ ma ọ bụ agba, mkpuchi dị n'ime kwesịrị inye nguzogide corrosion siri ike, nguzogide kemịkalụ, na nguzogide oke okpomọkụ. A na-ahọrọkarị mkpuchi epoxy resin ma ọ bụ mkpuchi polyolefin chlorinated, ebe ha na-egbochi mmeghachi omume kemịkal nke ọma ma chekwaa ọdịnaya.
Nchịkọta nke Ọrụ mkpuchi ime:
• Nguzogide corrosion: Na-egbochi mmeghachi omume n'etiti ọdịnaya na igwe, na-agbatị ndụ shelf.
• Mgbochi mmetọ: na-ezere ịtinye ekpomeekpo igwe ma ọ bụ ihe ndị ọzọ na-adịghị mma n'ime ihe dị n'ime ya, na-eme ka ọ dị mma.
• Njirimara njichi: Na-eme ka arụmọrụ akara nke ike ahụ dịkwuo elu, na-ahụ na ihe ndị dị na mpụga emetụtaghị ọdịnaya ya.
• Nguzogide oxidation: Na-ebelata ikpughe nke ọdịnaya na oxygen, na-egbu oge usoro oxidation.
• Nguzogide okpomọkụ: Ọ dị mkpa karịsịa maka ngwaahịa ndị na-eme nhazi okpomọkụ dị elu (dịka ọmụmaatụ, igba ogwu nri).
Ịhọrọ mkpuchi dị n'ime nke ọma nwere ike hụ na nchekwa na ịdị mma nke ngwaahịa a na-achịkọta mgbe ọ na-ezute ụkpụrụ nchekwa nri na ihe ndị chọrọ gburugburu ebe obibi.
