Tam sim no, zinc plua plav (zinc hmoov) tau siv dav hauv ntau qhov chaw ntawm kev lag luam, nrog rau hauv cov tshuab hluav taws xob kom muab cov nplaim hluav taws thiab cov hluav taws kub hnyiab xiav. Cia peb xav paub ntau ntxiv txog lub hom phiaj uas siv cov tshuaj no, nws muaj pes tsawg leeg thiab muaj txiaj ntsig zoo.

Applications

Siv dav ntawm zinc hmoov tau txais:

  • hauv kev lag luam tshuaj hauv kev tsim cov polymers, nrog rau cov muab tub lim rau lubricants;
  • hauv hydroelectrometallurgy thiab hmoov metallurgy;
  • thaum mining kub thiab nyiaj (kom tshem tawm cov hlau muaj txiaj ntsig los ntawm cov tshuaj cyanide);
  • hauv hydrogen zog;
  • hauv kev tsim cov tshuaj lom neeg tam sim no;
  • nyob rau hauv kev lag luam kws tshuaj;
  • hauv kev kho dej khib nyiab;
  • rau kev sib txuas ntawm cov organic tebchaw.

Zinc hmoov yog dav siv rau kev tsim khoom ntawm ntau yam tshuaj tiv thaiv corrosion uas tau siv ntau yam haujlwm ntawm engineering. Tsis tas li ntawd, nws yog ib feem ntawm cov xim thiab primers, nrog kev pab ntawmuas txuas hniav, nkoj thiab ntau yam qauv tiv thaiv los ntawm cov xwm txheej hnyav uas lawv ua haujlwm.

Tam sim no, kev lag luam tsim ntau qib thiab kev hloov kho ntawm zinc hmoov, uas txawv ntawm cov tshuaj muaj pes tsawg leeg thiab cov khoom me me thiab cov duab. Muaj cov hmoov hmoov ntawm kheej kheej, elliptical zoo, nrog rau hauv daim ntawv ntawm flakes.

Raws li GOST, zinc hmoov yog cais raws li hauv qab no:

  • chav kawm A suav nrog cov qib kho cov hmoov nplej nrog cov qauv zoo;
  • Qib B sib xyaw cov khoom ntxhib txau.

Zinc hmoov muaj cuaj caum-tsib rau cuaj caum-yim feem pua zinc, nrog rau me me ntawm impurities nyob rau hauv daim ntawv ntawm ib co lwm yam hlau.

khaws cia thiab ceev faj

Zinc hmoov nruas yuav tsum muab khaws cia rau hauv lub tsev khaws khoom kaw tsis muaj tshuaj hnyav.

Dej yuav tsum tiv thaiv kom tsis txhob nkag mus rau hauv cov hmoov ntim thaum lub sijhawm ntim khoom, kev thauj mus los thiab khaws cia, txij li zinc oxide tsim cov hydrogen los ntawm kev ua haujlwm maj mam nrog noo noo los ntawm ib puag ncig.

Thaum ua haujlwm nrog zinc hmoov, kev haus luam yeeb thiab kev siv hluav taws qhib raug txwv. Txhawm rau kom ntseeg tau tias muaj kev nyab xeeb, tsawg kawg ib hlis ib zaug, ntxuav qhov chaw hauv qhov chaw ntawm sifting thiab ntim cov hmoov, cheb cov phab ntsa thiab cov khoom siv.

Kev siv cov hmoov zinc hauvxim Industry

Cov cuab yeej ntawm zinc los tiv thaiv corrosive nres tau ntev tau siv los ntawm cov tuam ntxhab ntawm cov xim pleev xim rau txheej txheej hlau. Cov txheej txheem zoo li no siv zinc plua plav thiab flakes ua rau cov khoom siv hlau ua kom muaj kev ntxhov siab thiab tiv thaiv lawv ntawm corrosion.

Ntau cov zinc muab tub lim ntau hauv cov txheej txheem ntawm cov txheej txheem ua rau muaj kev tiv thaiv ntawm cov xim, tab sis txo lub zog ntawm cov txheej, uas thaum kawg pib tawg thiab flake tawm. Txhawm rau daws qhov teeb meem no, nws yuav tsum tau txo cov ntsiab lus ntawm cov muab tub lim rau 25 g ntawm zinc hmoov ib puas grams ntawm cov muaj pes tsawg leeg, nrog rau kev hloov cov qauv ntawm cov muab tub lim thiab ntxiv cov khoom pab rau cov xim - ntau yam organic resins thiab kua. iav. Txhawm rau txhim kho cov khoom muaj txiaj ntsig zoo ntawm cov txheej txheem no, ntau yam tshuaj ntxiv tuaj yeem ntxiv rau hauv daim ntawv ntawm hardeners, aqueous phosphates, inhibitors, silicates, thiab ntsev ntawm chromic acid. Qhov tseeb, zinc xim yog ib hom tshwj xeeb ntawm primer, vim nws yog siv rau thawj txheej txheej hlau thiab cov khoom.

Txoj khoom ntawm zinc xim

Cov xim, uas muaj cov khoom ntim hauv cov hmoov zinc, tiv taus cov dej noo, nrog rau cov khoom siv roj thiab cov kuab tshuaj organic.

Zinc xim tuaj yeem siv ncaj qha rau xeb yam tsis muaj pretreatment ntawm cov hlau. Cov xim no muaj kev puas tsuaj siab thiab ua rau muaj kev ntxhov siab ntau ntxiv.

Kev siv cov xim zinc tso cai rau koj los tiv thaiv cov qauv hlau los ntawm cov teebmeem ntawm huab cua tsis zoo rau txog nees nkaum tsib xyoos.

Kev siv cov xim zinc

Ua ntej siv cov xim zinc, qhov saum npoo yuav tsum tau npaj, uas yog, tshem tawm cov xeb thiab txhua yam kab mob. Ua li no, nws yog ntxuav nrog dab dawb los yog ib qho hnyav.

Tam sim ua ntej siv, cov xim yuav tsum tau muab sib xyaw kom zoo rau qhov sib xws ntawm qhov nruab nrab ntom ntom. Yog tias nws tau dhau los ua tuab, koj tuaj yeem dilute nws nrog toluene. Qhov zoo tshaj plaws kub rau dyeing yog nruab nrab ntawm tsib mus rau plaub caug degrees saum toj no zero.

Txhawm rau siv qhov sib xyaw rau saum npoo, siv lub flywheel lossis txhuam nruab nrab. Koj tseem tuaj yeem siv cov menyuam. Rau kev pleev xim rau qhov chaw loj, koj tuaj yeem siv rab phom tsuag. Thaum thawj txheej dries, tom qab ib teev thiab ib nrab, ob txheej txheej yog thov. Ib lub lis piam tom qab tha xim, cov khoom yog npaj txhij rau siv nyob rau hauv lub niaj zaus hom.
