isigubhu sokwelashwa kwangaphambili & Ukushisisa Isithombe Esifakiwe

Incazelo emfushane:

I-PRETREATMENT DRUM & HEATING ucezu lwesisetshenziswa esisetshenziswa ekukhiqizeni izimboni ukuze kulungiswe kuqala izinto ezingavuthiwe. Ngokuvamile iqukethe umgqomo ojikelezayo wokwelashwa kanye nesistimu yokushisisa. Ngesikhathi sokusebenza, izinto zokusetshenziswa zifakwa emgqonyeni ojikelezayo wokwelashwa wangaphambi kokwelashwa futhi zishiswe yisistimu yokushisa. Lokhu kusiza ukuguqula izakhiwo ezingokomzimba noma zamakhemikhali zempahla eluhlaza, okwenza kube lula ukuyiphatha ngesikhathi sezinqubo zokukhiqiza ezilandelayo. Lolu hlobo lwemishini luvamise ukusetshenziswa embonini yamakhemikhali, ekucutshungulweni kokudla, ezamakhemisi nakwezinye izimboni ukuthuthukisa ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo.

Incazelo Yomkhiqizo

Ukwelashwa kwangaphambi kwesikhathi kuyinqubo eyinhloko yokufaka uthayela oshisayo, okunomthelela omkhulu eqophelweni lemikhiqizo eyenziwe ngamagalani. Ukushisa kwangaphambi kokwelashwa kuhlanganisa: ukwehlisa, ukususa ukugqwala, ukugeza amanzi, usizo lokucwenga, inqubo yokomisa, njll.
Njengamanje, embonini yasekhaya ye-hot-dip galvanizing, ithangi le-granite pickling likakhonkolo lisetshenziswa kakhulu. Ngokwethulwa kobuchwepheshe obuphambili bokucwenga amadiphu e-hot-dip e-Europe naseMelika, amathangi okukhetha i-PP (polypropylene)/PE (polyethylene) aya ngokuya esetshenziswa kweminye imigqa yokukhiqiza yokufaka ama- hot-dip galvanizing ezenzakalelayo.

Ngokuya ngobunzima bebala likawoyela endaweni yokusebenza, ukwehlisa kuyasuswa kwezinye izinqubo.

Ithangi lokuwasha, ithangi lokugeza amanzi kanye nethangi losizo lokucwenga ngokuvamile kwakhiwa ukhonkolo, kanti okunye kwenziwa ngezinto ezifanayo nethangi lokuqopha.

Ukushisa kokwelashwa kwangaphambili

Sebenzisa ukushisa kwemfucuza kwegesi eshisayo ukushisa wonke amathangi okwelashwa kwangaphambili, okuhlanganisa nokuwasusa amafutha,ukukhakanye ne-axiliary plating. Isistimu yokushisa imfucuza ihlanganisa:
1) Ukufakwa komshini wokushisa ohlangene ku-flue;
2) Isethi eyodwa yesishintshi sokushisa se-PFA ifakwe kuzo zombili iziphetho zechibi ngalinye;
3) Uhlelo lwamanzi athambile;
4) Uhlelo lokulawula.
Ukushisisa ngaphambi kokwelashwa kunezingxenye ezintathu:
① Isishintshi sokushisa segesi engu-Flue
Ngokusho kwenani eliphelele lokushisa okufanele lishiswe, isishintshi sokushisa esihlanganisiwe se-flue siklanyelwe futhi senziwa, ukuze ukushisa kuhlangabezane nezidingo zokushisa. Uma kuphela ukushisa kwemfucuza kwe-flue kungakwazi ukuhlangabezana nesidingo sokushisa sokushisa kokwelashwa kwangaphambili, isethi yesithando somlilo esishisayo singangezwa ukuze kuqinisekiswe ivolumu yegesi ye-flue.
Isishintshi sokushisa senziwe ngensimbi engagqwali engashi noma ipayipi lensimbi elingenamthungo elingu-20 # eline-infrared nano high-temperature yokonga amandla okonga ukubola. Amandla okumunca ukushisa angu-140% wokushisa okumuncwa isishintshi sokushisa esivamile semfucuza.
② Isishintshi sokushisa se-PFA
③Ukomisa ihhavini
Lapho umkhiqizo onobuso obumanzi ungena kubhavu we-zinc, uzokwenza ukuthi uketshezi lwezinki luqhume futhi luchaphaze. Ngakho-ke, ngemva kosizo lokucwenga, inqubo yokomisa kufanele futhi yamukelwe izingxenye.
Ngokuvamile, izinga lokushisa lokumisa akufanele lidlule i-100 ° C futhi akufanele libe ngaphansi kuka-80 ° C. Uma kungenjalo, izingxenye zingafakwa kuphela emgodini wokomisa isikhathi eside, okuzokwenza kalula ukumuncwa komswakama we-zinc chloride kusawoti. ifilimu ye-plating aid ebusweni bezingxenye.
