Iindaba

Abaninzi abasaqalayo bawela emgibeni xa bethenga iiroli ezigqunywe ngombala ngenxa yokuba abaziqondi izinto zabo. Ke, yeyiphi imathiriyeli efanelekileyo kwimiqulu egqunywe ngombala?
I-substrate ye-coil coil coil ingaba yi-coil-rolled coil okanye i-hot-dip electroplated steel. Nangona i-organic coil ye-coil material ine-anti-corrosion effect, kusekho izikhewu ezincinci kwi-organic coating, ezinokuvumela umoya kunye nokufuma ukuba kungene kwaye kubangele ukurusa kwe-substrate. Ke ngoko, iikhoyili ezinemibala eqatywe ngemibala eyenziwe kwii-substrates ezingafakwanga zinobomi obufutshane benkonzo kwaye zithambekele ekusasazeni kunye nokwaleka ukuxobuka emva kokukrwelwa. I-substrate ye-coil yensimbi enombala ifakwe ipleyiti yentsimbi okanye i-alloy metal galvanized for steel plate technology. Kweminye imigca yokuvelisa, inkqubo yokuvelisa i-colored coatings yahlulwe ibe yi-substrate pre-treatment, i-chemical conversion coatings (i-non-organic metal coatings), i-organic non-metallic coatings, kunye ne-post-coating process.

I-1, i-Substrate pre-treatment: Ukuba asiyiyo inkampani enokungena ngokuthe ngqo kwinkqubo yokugquma kombala woluntu emva kwemveliso, iipleyiti zentsimbi ezisetyenziselwa njenge-substrates zingaqhubeka zifumana umhlwa (umhlwa omhlophe), uthuli kunye nolunye ungcoliseko ngexesha lokuthutha kunye nophuhliso. . Ukuba ezi azikwazi ukususwa, umgangatho wepeyinti uya kuchaphazeleka. Umgangatho wemiqulu egqitywe ngombala ogqityiweyo kunye nokusebenza kobugcisa bomzimba kunye neekhemikhali zabo bonke abafundi zinxulumene ngokusondeleyo nonyango lwangaphambili. Ukongezelela, ekuveliseni i-galvanizing, ukwenzela ukukhusela i-rust kunye ne-oiling, ezi oyile zikwasuswa ngaphambi kokuveliswa kombala. Indlela exhaphakileyo yonyango lwangaphambili ngoku yisisombululo sealkaline yokususa igrisi.
2, Ifilimu yokuguqula imichiza inemisebenzi emibini
Enye kukuphucula ngakumbi amandla okuthintela umhlwa,
Okwesibini kukuphucula ukubambelela phakathi kwe-substrate kunye nokugqoka, kunye nokuphucula ukusebenza kwengubo ye-substrate.

Kukho amanyathelo amathathu ngokubanzi:
Enye i-phosphating, eqala ukwenza inani elikhulu leekristale kumphezulu wesinyithi, kwaye emva koko yenza umaleko wefilimu ye-phosphate phezu kwesinyithi kunye nesisombululo setyuwa ye-phosphate;
Okwesibini kukudlula kunye nokutywinwa. Ifilimu ye<em>phosphate isenayo imingxunya ethile, eshukunyiswa ngokwekhemikhali ngeechromates ukwenza ifilimu ekhuselayo. Okwesithathu, hlamba ngamanzi acocekileyo kwaye ususe isisombululo se-passivation nge-desalinated okanye i-deionized water.
3, Iingubo ze-Organic zohlulwe ikakhulu kwi-primer kunye ne-topcoat. Iimfuno ze-Primer azikho phezulu kwaye zinokusetyenziswa ngendlela egudileyo yombala. Nangona kunjalo, ukuze kuphuculwe ukhuseleko lolwazi lwemveliso, amashishini aseTshayina ngokuqhelekileyo asebenzisa indlela yokwaleka umbala we-primer kunye ne-topcoat.
Inkqubo yokupakisha iposi: Inkqubo yokugubungela isithuba ibandakanya ukuprintwa, ukubethelwa, ifilimu yokukhusela i-peelable, i-bonding, njl., Ephucula iimpawu zokuhlobisa kunye nokukhusela ibhodi efakwe umbala.
