Dacromet' cov khoom xyaw tseem ceeb:
Muaj ntau ntau hom Dacromet txheej cov kua, tab sis cov ntsiab lus tseem ceeb ntawm cov kua txheej txheej tuaj yeem ua tiav raws li hauv qab no:
1. Hlau: Nws yog tsim los ntawm zinc, txhuas thiab lwm yam khoom, feem ntau yog ultra-fine flake zinc thiab ultra-fine flake aluminium; 2. Solvent: ib qho inert organic hnyav, xws li ethylene glycol, thiab lwm yam.; 3. Inorganic acid Cheebtsam: xws li Chromic acid, thiab lwm yam.; 4. Cov organic teeb meem tshwj xeeb: nws yog cov thickening thiab dispersing tivthaiv ntawm txheej kua, lub ntsiab tivthaiv yog dawb cellulose hmoov.
Anti-corrosion mechanism:
Cov nyhuv tiv thaiv ntawm Dacromet zaj duab xis ntawm cov hlau substrate tuaj yeem ua tiav raws li hauv qab no:
Barrier effect: vim yog txheej txheej txheej txheej ntawm flake zinc thiab txhuas, nws cuam tshuam cov txheej txheem ntawm dej, oxygen thiab lwm yam corrosive media los ntawm kev ncav cuag lub substrate, uas tuaj yeem ua raws li kev sib cais tiv thaiv; Cov nyhuv passivation: nyob rau hauv cov txheej txheem kev kho mob ntawm Dacromet, chromic acid Nws chemically reacts nrog zinc, txhuas hmoov thiab hauv paus hlau los ua ib tug tuab passivation zaj duab xis, uas muaj corrosion kuj zoo; cathodic tiv thaiv: lub ntsiab tiv thaiv nyhuv ntawm zinc aluminium chromium txheej thiab zinc txheej tib yam yog cathodic tiv thaiv ntawm substrate.
Qhov zoo:
Dacromet yog ib hom tshiab ntawm kev kho deg technology. Piv nrog rau cov txheej txheem electroplating ib txwm, Dacromet yog ib hom" ntsuab plating". Nws qhov zoo yog raws li nram no:
Super corrosion resistance: Lub thickness ntawm Dacromet zaj duab xis tsuas yog 4-8μm, tab sis nws cov nyhuv anti-xeb yog ntau tshaj li 7-10 npaug ntawm cov tsoos electro-galvanizing, kub-dip galvanizing lossis xim txheej. Cov txheej txheem thiab cov yeeb nkab pob qij txha kho nrog cov txheej txheem Dacromet tsis pom cov xeb liab tom qab cov ntsev tsuag tshuaj tiv thaiv rau ntau tshaj 1200 teev.
Tsis muaj hydrogen embrittlement: Dacromet' cov txheej txheem ua haujlwm txiav txim siab tias Dacromet tsis muaj qhov tshwm sim hydrogen embrittlement, yog li Dacromet yog qhov tsim nyog rau txheej txheej ntawm qhov nyuaj.
Kev kub siab ua haujlwm: Dacromet tuaj yeem tiv taus qhov kub thiab txias, thiab qhov kub tsis kam tiv thaiv tuaj yeem ncav cuag 300 ℃. Cov txheej txheem galvanizing ib txwm raug muab pov tseg thaum kub txog 100 ° C.
Zoo adhesion thiab recoating kev ua tau zoo: Dacromet txheej muaj adhesion zoo rau cov hlau substrate, thiab muaj zog adhesion rau lwm cov txheej ntxiv. Cov txheej txheem txheej txheem yog yooj yim rau tshuaj tsuag thiab xim, thiab cov adhesion rau cov organic coatings yog ntau tshaj cov phosphate txheej.
Zoo permeability: Vim lub electrostatic shielding nyhuv, nws yog ib qho nyuaj rau electroplate qhov sib sib zog nqus qhov, slits, puab phab ntsa ntawm cov yeeb nkab fittings thiab lwm qhov chaw ntawm lub workpiece nrog zinc. Yog li ntawd, cov lus hais saum toj no ntawm lub workpiece tsis tuaj yeem tiv thaiv los ntawm electroplating. Dacromet tuaj yeem nkag mus rau cov ntu ntawm cov khoom ua haujlwm los ua cov txheej Dacromet.
Tsis muaj kuab paug thiab muaj kuab paug: Dacromet yuav tsis tsim ib puag ncig ua rau cov dej khib nyiab thiab cov pa khib nyiab pov tseg thaum lub sij hawm tag nrho cov txheej txheem ntawm kev tsim, kev ua haujlwm thiab txheej txheej workpiece, thiab tsis tas yuav kho peb cov khib nyiab, uas txo cov nqi kho mob.
Cov kev ceev faj:
1. Dacromet yuav muaj hnub nyoog sai heev thaum raug lub teeb, yog li txheej txheem txheej ntawm Dacromet yuav tsum tau nqa tawm hauv tsev.
2. Dacromet' s ci kub tsawg dhau los yog siab dhau yuav ua rau Dacromet poob nws lub peev xwm los tiv thaiv corrosion. Dacromet yuav tsum tau ci nyob rau hauv ib tug haum kub ntau yam.
3. Dacromet' lub neej voj voog luv heev, yog li nws yuav tsum tau siv kom sai li sai tau.
4. Dacromet muaj kev puas tsuaj tsis zoo, yog li Dacromet yuav tsum tau muab tso rau sab saum toj, thiab tom qab ntawd lwm cov coatings uas muaj kev puas tsuaj yuav tsum tau siv.
