Nyocha nke usoro ọgwụgwọ elu nke galvanized ígwè grating tupu eserese

Hot-mikpu galvanizing (na-ekpo ọkụ-mikpu galvanizing maka mkpụmkpụ) n'elu nke ígwè grating bụ ihe kasị nkịtị na irè n'elu nchebe technology maka ịchịkwa gburugburu ebe obibi corrosion nke ígwè akụkụ. Na gburugburu ikuku ikuku, mkpuchi na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ na-enweta site na nkà na ụzụ a nwere ike ichebe akụkụ ígwè site na nchara ruo ọtụtụ afọ ma ọ bụ karịa afọ 10. Maka akụkụ na-enweghị ihe mgbochi pụrụ iche chọrọ, ọ dịghị mkpa maka ọgwụgwọ mgbochi corrosion nke abụọ (spraying ma ọ bụ eserese). Otú ọ dị, iji chekwaa ụgwọ ọrụ nke ngwá ọrụ na ụlọ ọrụ, belata mmezi, na n'ihu ịgbatị ndụ ọrụ nke ígwè grating na gburugburu ebe siri ike, ọ na-adị mkpa ka a rụọ ọrụ nchebe nke abụọ na-ekpo ọkụ na-ekpo ọkụ galvanized ígwè grating, ya bụ, tinye okpomọkụ organic mkpuchi na-ekpo ọkụ-imenye galvanized elu na-etolite a okpukpu abụọ-layer mgbochi corrosion usoro.
Ọtụtụ mgbe, ígwè gratings na-adịkarị passivated online ozugbo na-ekpo ọkụ-mikpu galvanizing. N'oge usoro ngafe, mmeghachi omume oxidation na-eme n'elu mkpuchi mkpuchi galvanizing na-ekpo ọkụ na interface nke ngwọta passivation, na-eme ihe nkiri passivation siri ike na nke siri ike n'elu akwa galvanizing na-ekpo ọkụ, nke na-ekere òkè n'ịkwalite nguzogide corrosion nke oyi akwa zinc. Otú ọ dị, n'ihi na ígwè gratings nke kwesịrị ka ntekwasa na a okpomọkụ primer na-etolite a okpukpu abụọ-layer mgbochi corrosion usoro maka nchebe, na ok, ire ụtọ, na passivation metal passivation film siri ike ijikọ tightly na ụdi okpomọkụ primer, na-akpata na akaghi aka bubbling na Nwụfu nke organic mkpuchi n'oge ọrụ, na-emetụta ya na-echebe mmetụta.
Iji nwetakwuo ịdịte aka nke grating nchara na-eji galvanizing na-ekpo ọkụ na-ekpo ọkụ, ọ ga-ekwe omume na-ekpuchi mkpuchi organic kwesịrị ekwesị n'elu ya iji mepụta usoro nchebe ngwakọta maka nchebe. Nyere na elu nke akwa akwa galvanized na-ekpo ọkụ na-ekpo ọkụ nke ígwè grating bụ nke dị larịị, dị nro, na mgbịrịgba, ike njikọ dị n'etiti ya na usoro mkpuchi na-esote ezughị oke, nke nwere ike iduga n'ụzọ dị mfe na-agbapụta, nkwụsị, na ọdịda ọdịda nke mkpuchi. Site na ịhọrọ primer kwesịrị ekwesị ma ọ bụ usoro ọgwụgwọ kwesịrị ekwesị, ike nke njikọ dị n'etiti mkpuchi zinc / ihe mkpuchi mbụ nwere ike ime ka ọ dịkwuo mma, na-enwe ike ịmepụta mmetụta nchebe ogologo oge nke usoro nchebe nke mgbagwoju anya.
Nkà na ụzụ isi nke na-emetụta mmetụta nchebe nke usoro mkpuchi mkpuchi na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ na-ekpuchikwa usoro ọgwụgwọ elu tupu mkpuchi. Sandblasting bụ otu n'ime ụzọ ọgwụgwọ elu nke a na-ejikarị na nke a pụrụ ịdabere na ya maka mkpuchi nchara nchara, mana n'ihi na elu galvanized na-ekpo ọkụ na-ekpo ọkụ dị nro, oke nrịbama ájá na nha nha ájá nwere ike ime ka mfu nke akwa galvanized nke ígwè grating. Site n'ịchịkwa nrụgide ịgba na nha nha nke ájá, obere sandblasting n'elu nke na-ekpo ọkụ na-ekpo ọkụ galvanized ígwè grating bụ usoro ọgwụgwọ elu dị irè, nke nwere mmetụta na-eju afọ na ngosipụta nke primer, na ike njikọ dị n'etiti ya na oyi akwa galvanized na-ekpo ọkụ dị ukwuu karịa 5MPa.
Iji a cyclic hydrogen primer nwere zinc phosphate, adhesion n'etiti zinc mkpuchi/organic primer bụ isi ihe karịrị 5MPa na-enweghị sandblasting. Maka elu igwe na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ, mgbe ọ na-adịghị mma iji ọgwụgwọ elu ájá ájá, mgbe a na-atụle ihe mkpuchi organic ọzọ mgbe e mesịrị, a pụrụ ịhọrọ primer nke nwere phosphate, n'ihi na phosphate na primer na-enyere aka imeziwanye nchikota nke ihe nkiri agba ma welie mmetụta mgbochi corrosion.
Tupu etinyere primer na mgbidi mkpuchi, akwa galvanized na-ekpo ọkụ na-ekpo ọkụ nke grating ígwè na-agafe ma ọ bụ na-agafe agafe. Usoro ọgwụgwọ ahụ enweghị mmetụta dị ịrịba ama n'ịkwalite adhesion, na ịṅụ mmanya na-egbu egbu enweghị mmetụta nkwalite doro anya na ike njikọ dị n'etiti mkpuchi zinc / primer.
