Finyelela Ikhwalithi Ephakeme Ngesigubhu Nokushisa Ngaphambi Kokwelashwa
Incazelo Yomkhiqizo
- Sethula uhlelo lwethu lokuguqula izigubhu zangaphambi kokwelashwa kanye nohlelo lokushisa. Njengamaphayona embonini ye-hot-dip galvanizing, siyaqonda indima ebalulekile edlalwa yi-pre-treatment ekuqinisekiseni ikhwalithi ephezulu yemikhiqizo ye-galvaning. Ngobuchwepheshe obuthuthukisiwe kanye nomklamo omusha, sihlose ukuguqula indlela okwenziwa ngayo ukwelapha kwangaphambi kokwelashwa.
Ngokwesiko, imboni ye-hot-dip galvanizing yasekhaya ithembele emathangini okufaka ukhonkolo kanye ne-granite ukuze kufudunyezwe ngaphambi kokwelashwa. Kodwa-ke, ngokwethulwa kobuchwepheshe be-hot-dip galvanizing obusezingeni eliphezulu eYurophu nase-United States, isidingo sezinye izindlela ezisebenzayo nezithembekile siyaqhubeka nokukhula. Yilapho-ke amathangi ethu okufaka ukhonkolo e-PP (polypropylene)/PE (polyethylene) eqala khona ukusebenza.
Ama-drum ethu angaphambi kokwelashwa kanye nezinhlelo zokushisa zihlanganisa izinqubo eziyisisekelo zokususa amafutha, ukususa ukugqwala, ukuwasha ngamanzi, ukufaka izithasiselo zokufaka ama-plating kanye nokomisa kube umsebenzi owodwa ongenamthungo. Ngalesi sixazululo esiphelele siqeda isidingo samatangi amaningi okugcina futhi senze lula yonke inqubo yokwelapha. Lokhu akugcini nje ngokuthuthukisa ukusebenza kahle kodwa futhi kunciphisa nezindleko zokusebenza.
Inzuzo eyinhloko yama-drum ethu kanye nezinhlelo zokushisa zangaphambi kokwelashwa ukusetshenziswa kwezinto ze-PP/PE. Lezi zinto zaziwa ngokumelana kwazo okuhle kakhulu nokugqwala kanye nokuwohloka kwamakhemikhali. Ngenxa yalokho, amathangi ethu okupheka anikeza ukusebenza okuphezulu nokuqina okuphezulu uma kuqhathaniswa namathangi ekhonkrithi endabuko. Ukusetshenziswa kwalezi zinto kuqinisekisa nokuthi izinhlelo zethu zinobungani nemvelo futhi ziyahambisana nezindinganiso zemvelo zomhlaba wonke.
Ngaphezu kokusebenzisa izinto ezisezingeni eliphezulu, ama-drum ethu okulungisa izinto kanye nezinhlelo zokushisa zihlonyiswe ngobuchwepheshe bokushisa obusezingeni eliphezulu. Lokhu kuqinisekisa ukulawulwa kokushisa okunembile nokungaguquguquki kuyo yonke inqubo yokulungisa izinto, okuthuthukisa ikhwalithi yomkhiqizo oqinisiwe. Uhlelo lunomklamo olula futhi olusebenziseka kalula futhi kulula ukulusebenzisa nokunakekela.
Kungakhathaliseki ukuthi unesikhungo esincane sokufaka i-galvanizing noma isitshalo esikhulu sezimboni, ama-drum ethu okulungisa kanye nezinhlelo zokushisa zenzelwe wena ukuze zihlangabezane nezidingo zakho ezithile. Sinikeza izinketho ezingenziwa ngokwezifiso ukuze zivumelane nobukhulu nobukhulu bokukhiqiza obuhlukahlukene. Ngemikhiqizo yethu, ungayisa imisebenzi yakho yokufaka i-galvanizing ezingeni elisha lokusebenza kahle, ukukhiqiza kanye nekhwalithi.
Joyina inguquko yokushisa ngaphambi kokwelashwa nge-hot dip galvanizing. Tshala imali kuma-drum ethu angaphambi kokwelashwa kanye nezinhlelo zokushisa bese uzwa amandla okuguqula ubuchwepheshe obuthuthukisiwe. Themba ubuchwepheshe bethu futhi sikuvumele sikusize ufinyelele amazinga aphezulu kakhulu emikhiqizo yakho ye-galvaning. Xhumana nathi namuhla ukuze ufunde kabanzi ngezixazululo zethu ezintsha.
Ukushisa kwangaphambi kokwelashwa
Sebenzisa ukushisa okulahliwe kwegesi yoketshezi ukuze ufudumale wonke amathangi angaphambi kokwelashwa, okuhlanganisa ukususa amafutha, ukugabha kanye nokufaka iplati yokusiza. Uhlelo lokushisa olulahliwe luhlanganisa:
1) Ukufakwa kwe-heat exchanger ehlanganisiwe ku-flue;
2) Isethi eyodwa ye-PFA heat exchanger ifakiwe kuzo zombili iziphetho zechibi ngalinye;
3) Uhlelo lwamanzi athambile;
4) Uhlelo lokulawula.
Ukushisa kwangaphambi kokwelashwa kuqukethe izingxenye ezintathu:
① Isishintshi sokushisa segesi yoketshezi
Ngokwenani eliphelele lokushisa okufanele kufudunyezwe, i-combined flue heat exchanger yaklanywa futhi yakhiqizwa, ukuze ukushisa kuhlangabezane nezidingo zokushisa. Uma ukushisa okulahliwe kwe-flue kungakwazi ukuhlangabezana nesidingo sokushisa sokushisa sokwelashwa kwangaphambi kokwelashwa, isethi yesithando somoya oshisayo singangezwa ukuqinisekisa ivolumu yegesi ye-flue.
I-heat exchanger yenziwe ngensimbi engagqwali engamelani nokushisa noma ipayipi lensimbi elingenamthungo elingu-20 # eline-infrared nano high-temperature anti-corrosion coating entsha. Amandla okumunca ukushisa angama-140% okushisa amuncwa yi-waste heat exchanger evamile.
② Isishintshi sokushisa se-PFA
③ Ihhavini elomile
Uma umkhiqizo omanzi ungena ebhavini le-zinc, kuzobangela ukuthi uketshezi lwe-zinc luqhume futhi luchitheke. Ngakho-ke, ngemva kosizo lokufaka iplati, inqubo yokomisa kufanele futhi isetshenziswe ezingxenyeni.
Ngokuvamile, izinga lokushisa lokomisa akufanele lidlule ku-100 ° C futhi akufanele libe ngaphansi kuka-80 ° C. Ngaphandle kwalokho, izingxenye zingafakwa kuphela emgodini wokomisa isikhathi eside, okuzobangela kalula ukumuncwa komswakama kwe-zinc chloride efilimini kasawoti ye-plating aid ebusweni bezingxenye.
