Umahluko phakathi kwe-Hot-Dip Galvanizing kunye ne-Mechanical Galvanizing

Ukugalela idiphu eshushu yinkqubo yonyango yomphezulu ebandakanya ukuntywiliselwa kwamalungu anyangwe kwangaphambili kwibhafu ye-zinc ukwenzela ukusabela kwesinyithi esinobushushu obuphezulu ukwenza i-zinc yokugquma Amanyathelo amathathu okugalela idiphu eshushu ngolu hlobo lulandelayo:

① Umphezulu wemveliso unyibilikiswa lulwelo lwe-zinc, kwaye indawo esekwe yintsimbi inyibilika ngolwelo lwezinc ukwenza isigaba se-zinc iron alloy.

② Ii-ion ze-zinc kumaleko we-alloy zisasazeka ngakumbi ukuya kwi-matrix ukwenza umaleko we-zinc wesisombululo esihlangeneyo; Intsimbi yenza i-zinc iron alloy ngexesha lokuchithwa kwesisombululo se-zinc kwaye iyaqhubeka isasazeka ngokubhekiselele kwindawo ejikelezileyo Umphezulu we-zinc iron alloy layer ihlanganiswe ne-zinc layer, epholisa kwaye ikhanye kwiqondo lokushisa eliqhelekileyo ukuze yenze i-coating. Okwangoku, inkqubo yokudibanisa idiphu eshushu yeebholiti iye igqibelele kwaye izinzile, kwaye ubukhulu bengubo kunye nokumelana nomhlwa kunokuhlangabezana ngokupheleleyo neemfuno zokuchasana nokubola kwezixhobo ezahlukeneyo zoomatshini. Nangona kunjalo, kusekho ezi ngxaki zilandelayo kwimveliso yokwenyani kunye nokufakwa kwezixhobo zoomatshini:

1. Kukho inani elincinci le-zinc eseleyo kwintambo ye-bolt, echaphazela ukufakela,

2. Impembelelo kumandla okudibanisa ngokubanzi iphunyezwa ngokwandisa isibonelelo somatshini we-nut kunye nokucofa emva emva kokucwenga ukuqinisekisa ukulungelelaniswa phakathi kwe-nut-galvanized nut kunye nebholithi. Nangona oku kuqinisekisa ukufaneleka kwe-fastener, uvavanyo lokusebenza koomatshini luhlala lusenzeka ngexesha lenkqubo yokuqina, echaphazela amandla oqhagamshelwano emva kofakelo.

3. Impembelelo kwiimpawu zomatshini we-bolts-high-power bolts: Inkqubo ye-galvanizing engafanelekanga eshushu-dip inokuchaphazela ukuqina kwempembelelo yeebholiti, kunye nokuhlamba i-asidi ngexesha lenkqubo ye-galvanizing kunokunyusa umxholo we-hydrogen kwi-matrix ye-10.9 grade-high-power bolts. , ukunyusa amandla okunyusa i-hydrogen embrittlement. Uphando luye lwabonisa ukuba iimpawu zomatshini zeendawo ezifakwe kwi-threaded bolts-high-power bolts (ibakala 8.8 nangaphezulu) emva kwe-galvanizing eshushu-dip inomlinganiselo othile womonakalo.

I-Mechanical galvanizing yinkqubo esebenzisa i-physical adsorption deposition, kunye ne-mechanical adsorption, kunye ne-mechanical adsorption ukwenza ukugquma komgubo wentsimbi kumphezulu we-workpiece kwiqondo lobushushu begumbi kunye noxinzelelo. Ngokusebenzisa le ndlela, iingubo zetsimbi ezifana neZn, Al, Cu, Zn-Al, Zn-Ti, kunye neZn-Sn zinokuqulunqwa kwiindawo zetsimbi, zibonelela ngokukhuselekileyo kwi-substrate yensimbi yensimbi. Inkqubo yokwenza i-galvanizing yomatshini ngokwayo inquma ukuba ubukhulu be-coating of threads kunye ne-grooves buncinci kunendawo ethe tyaba. Emva kokucoca, amandongomane awafuni ukucofa ngasemva, kwaye iibholiti ezingaphezulu kwe-M12 azidingi nokuba zigcine ukunyamezelana. Emva kokucoca, akuchaphazeli ukufaneleka kunye neempawu zoomatshini. Nangona kunjalo, ubukhulu be-particle ye-zinc powder esetyenzisiweyo kwinkqubo, ukunyanzeliswa kokutya ngexesha lokutya, kunye nexesha lokutya lichaphazela ngokuthe ngqo ukuxinana, ukucaca, kunye nokubonakala kwengubo, ngaloo ndlela ichaphazela umgangatho wengubo.
