SMLS Carbon Pipe Supplier-GNEE
- Ua ntej pickling thiab passivating seamless steel kav, roj, degreasing, thiab degreasing cov khoom sib txuas thiab lwm yam impurities yuav tsum tau muab tshem tawm. Qhov saum npoo ntawm cov yeeb nkab steel seamless tom qab pickling thiab passivation hloov mus rau hauv cov xim silvery dawb, uas zoo heev txhim kho corrosion kuj ntawm stainless hlau.
- Phosphating ntawm seamless steel kav yog txheej txheem uas seamless steel kav yog immersed nyob rau hauv ib tug phosphating tov (ib qho tshuaj raws li ib co acid phosphates) thiab tso rau ntawm qhov chaw los tsim ib txheej ntawm dej-insoluble crystalline phosphate hloov dua siab tshiab zaj duab xis. Phosphating yog ib txoj hauv kev uas cov tshuaj thiab cov tshuaj electrochemical ua rau cov tshuaj phosphate hloov dua siab tshiab. Cov phosphate hloov dua siab tshiab zaj duab xis yog hu ua phosphating zaj duab xis, uas tiv thaiv hlau los ntawm corroded mus rau ib qho twg;
- Nws yog siv los ua primer ua ntej pleev xim los txhim kho qhov adhesion thiab tiv thaiv corrosion ntawm cov xim zaj duab xis txheej; nws yog siv los txo kev sib txhuam thiab lubrication hauv cov txheej txheem hlau ua haujlwm.
- Cov "phosphating thiab saponification" ntawm seamless steel kav yog hais txog ib tug txheej txheem ntawm re-saponification tom qab phosphating. Nws feem ntau yog siv rau hauv cov txheej txheem machining xws li kos duab lossis ncab. Tom qab phosphating zaj duab xis feem ntau yog 8-12 microns, nws nkag mus rau hauv cov tshuaj saponification thiab ces rub los yog ncab.
- Lub hom phiaj ntawm saponification ntawm seamless steel kav yog los ua kom cov lubrication kev ua tau zoo.
- Cov txheej txheem luv luv ntawm pickling, phosphating thiab saponifying seamless steel yeeb nkab cov txheej txheem kev khiav hauj lwm: pickling → high pressure wash → phosphating → high pressure water washing → saponification → drying → transport and stacking.
