Rwb thaiv tsev tsis kam ntawm hluav taws xob cua sov raj ntawm chav tsev kub

Rwb thaiv tsev tsis kam ntawm hluav taws xob cua sov raj ntawm chav tsev kub

Los ntawm kev ntsuas lub armored thermode thiab rwb thaiv tsev tiv thaiv ntawm lub thermode thiab lub plhaub hlau ntawm chav tsev kub, qhov zoo ntawm armor tuaj yeem txiav txim siab. Yog li ntawd, chav tsev kub rwb thaiv tsev ntsuas cov khoom ntsuas tau teev tseg hauv JJF1262-2010.

Muaj pes tsawg txoj kev kho saum npoo muaj rau cov hlau extruders?

Sandblasting feem ntau yog siv los ntxuav qhov chaw. Sandblasting ua ntej tha xim (thaum pleev xim lossis pleev xim yas) tuaj yeem ua rau lub ntsej muag roughness, thiab muaj qee yam kev txhawb nqa rau kev txhim kho adhesion, tab sis qhov kev koom tes yog txwv, ib yam li ua ntej tshuaj pleev xim.
2. Xim: Muaj ob lub ntsiab xim txheej txheem rau txhuas: ib qho yog txhuas oxidation txheej txheem xim, thiab lwm yam yog txhuas electrophoretic xim txheej txheem. Ntau yam xim yog tsim los ntawm oxide zaj duab xis kom ua tau raws li qee qhov kev thov, xws li dub, kub puav pheej thiab lwm yam khoom siv kho qhov muag.
3. Conductive oxidation (chromate conversion txheej)-rau kev tiv thaiv thiab conductive zaus.
4. Tshuaj oxidation: Cov oxide zaj duab xis yog nyias, nrog ib tug tuab ntawm txog 0.5 ~ 4 microns, ntxeem tau, mos, thiab muaj zoo adsorption zog. Nws tuaj yeem siv los ua cov txheej hauv qab ntawm cov organic coatings, tab sis cov hnav tsis kam thiab corrosion kuj tsis zoo li anodic oxide zaj duab xis;
Cov txheej txheem tshuaj oxidation ntawm txhuas thiab txhuas alloys tuaj yeem muab faib ua alkaline oxidation thiab acidic oxidation raws li lawv cov yam ntxwv daws.
Raws li qhov xwm txheej ntawm zaj duab xis tuaj yeem muab faib ua: oxide zaj duab xis, phosphate zaj duab xis, chromate zaj duab xis, phosphate-phosphate zaj duab xis.
5. Electrochemical oxidation, aluminium thiab aluminium alloy chemical oxidation kev kho cov cuab yeej yog yooj yim, yooj yim rau kev khiav lag luam, siab ntau lawm efficiency, tsis siv zog, muaj ntau yam kev siv, thiab tsis txwv los ntawm qhov loj thiab cov duab ntawm qhov chaw. Lub thickness ntawm cov oxide zaj duab xis yog hais txog 5-20 microns (lub thickness ntawm lub hard anodized zaj duab xis yuav ncav cuag 60-200 microns), muaj zog hardness, zoo tshav kub kuj thiab rwb thaiv tsev, corrosion kuj yog ntau ntxeem tau tshaj tshuaj oxide. films, thiab muaj peev xwm adsorption zoo.
6. Txau: feem ntau yog siv rau kev tiv thaiv sab nrauv thiab khoom kho kom zoo nkauj ntawm lub hauv paus ntawm oxidation. Aluminium qhov chaw yuav tsum tau pretreated ua ntej tha xim kom cov xim thiab cov workpiece ua kom ruaj khov. Feem ntau, muaj peb txoj hauv kev: phosphating (phosphating method), chromium (chromium-free), thiab tshuaj oxidation.
8. Tshuaj polishing Tshuaj polishing yog ib txoj kev kho tshuaj uas siv txhuas thiab txhuas alloys los xaiv autodissolve nyob rau hauv acid los yog alkaline electrolyte daws kom du nto ntawm polishing system, txo qhov roughness, thiab PH. Txoj kev polishing muaj cov cuab yeej siv yooj yim, tsis muaj hluav taws xob, tsis txwv los ntawm qhov loj ntawm cov khoom, muaj kev kub ceev thiab cov nqi ua haujlwm tsawg. Lub purity ntawm txhuas thiab txhuas alloys muaj kev cuam tshuam zoo ntawm cov tshuaj polishing.
9. Passivation yog ua kom cov hlau nto nyob rau hauv ib lub xeev uas tsis yooj yim rau oxidize thiab ua kom cov corrosion ntawm cov hlau.
