xov xwm

Txhawm rau pleev xim rau phab ntsa, koj yuav tsum xaiv hom xim thiab xim dej.Txhua tus ntawm lawv muaj nws tus kheej zoo thiab cov yam ntxwv.Yog li ntawd, peb yuav txiav txim siab raws li lawv cov yam ntxwv ua haujlwm thaum xaiv.Txawm li cas los xij, ua ntej ntawm tag nrho cov, peb xav tau txhua tus ua ntej Ua tib zoo saib qhov tsis zoo ntawm cov xim dej.Koj yuav tsum paub nws qhov tsis zoo ua ntej koj tuaj yeem siv nws.Ntxiv mus, ntau tus neeg tseem tsis paub tias qhov sib txawv ntawm cov xim dej thiab xim yog dab tsi.

Disadvantages ntawm cov xim dej

Cov txheej txheem dej-raws li muaj kev xav tau siab ntawm kev ua kom huv ntawm cov txheej txheem tsim kho thiab qhov chaw ntawm cov khoom.Vim yog qhov loj ntawm qhov nro ntawm cov dej, cov av yuav ua rau shrinkage ntawm txheej zaj duab xis;Lub dispersion stability ntawm cov dej-raws li coatings tiv thaiv muaj zog mechanical zog yog tsis zoo, thiab cov txaus tus nqi nyob rau hauv lub conveying pipeline hloov sai heev Thaum cov dispersed hais yog compressed rau hauv cov khoom, cov zaj duab xis txheej yuav pitted.Nws yog qhov yuav tsum tau ua kom lub raj xa dej xa mus tau zoo thiab cov yeeb nkab phab ntsa tsis muaj qhov tsis xws luag.

Cov xim pleev xim rau hauv dej yog qhov muaj zog heev rau cov khoom siv txheej txheej, yog li yuav tsum muaj cov khoom siv los tiv thaiv corrosion los yog cov khoom siv hlau tsis muaj steel, thiab cov khoom siv raug nqi siab.Kev xeb ntawm cov xim pleev xim rau cov dej xa mus rau cov kav xa dej, kev sib cais ntawm cov hlau, nag lossis daus ntawm cov khoom tawg, thiab cov pitting ntawm cov yeeb yaj kiab txheej, kuj yuav tsum tau siv cov kav dej stainless hlau.

Ci dej-raws li txheej txheej muaj kev nruj me ntsis ntawm kev tsim kho ib puag ncig (kub, av noo), uas ua rau nce kev nqis peev hauv cov cuab yeej ntsuas kub thiab av noo, thiab tseem ua rau muaj zog siv zog.Lub latent cua sov ntawm evaporation ntawm dej yog loj, thiab lub zog noj ntawm ci yog loj.Cathodic electrophoretic txheej yuav tsum tau ci ntawm 180 ° C;latex coatings siv sij hawm ntev kom qhuav tag.Organic co-solvents nrog siab boiling point tsim ib tug ntau ntawm cov roj fumes thaum lub sij hawm ci, thiab poob rau saum npoo ntawm txheej zaj duab xis tom qab condensation los cuam tshuam cov tsos.

Qhov sib txawv ntawm cov xim dej thiab xim

1. Cov ntsiab lus txawv

Cov xim pleev xim rau hauv dej: Cov xim uas siv cov dej ua kom muaj dej.Nws muaj cov yam ntxwv ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, tsis yog-combustible thiab tsis tawg, ultra-low emission, low-carbon thiab noj qab nyob zoo.

Xim: Cov xim ua los ntawm benzene thiab lwm yam organic solvents raws li diluents los kho thiab tiv thaiv cov khoom.Benzene cov kuab tshuaj yog tshuaj lom thiab carcinogenic, muaj VOC emissions siab, yog nplaim taws thiab tawg, thiab ua paug rau ib puag ncig.

2. txawv diluents

Cov xim pleev xim dej: tsuas yog siv cov dej ua kom nyias nyias.

Xim: Cov xim siv cov tshuaj lom neeg muaj kuab lom, ua kuab paug thiab tawg tau cov kuab tshuaj organic raws li diluents.

3. txawv volatiles

Cov xim dej: feem ntau yog volatilization ntawm dej.

Xim: volatilization ntawm cov kuab tshuaj organic xws li benzene.

4. Cov kev tsim kho sib txawv

Cov xim dej: Tsis muaj cov cai tshwj xeeb.Tom qab kev cob qhia yooj yim, nws tuaj yeem pleev xim.Nws yog qhov yooj yim heev rau kev pleev xim thiab kho.Feem ntau, nws tsis xav tau kev pab ntawm cov khoom siv tiv thaiv kev ua haujlwm lossis kev kho hluav taws kub tshwj xeeb.Txawm li cas los xij, cov xim pleev xim dej dries kuj qeeb ntawm chav tsev kub thiab cuam tshuam zoo heev los ntawm qhov kub thiab txias.

Xim: Koj yuav tsum dhau los ntawm kev cob qhia thiab kev xyaum ua ntej koj tuaj yeem pleev xim, koj yuav tsum tau nruab nrog cov khoom siv tiv thaiv kev ua haujlwm, xws li lub qhov ncauj qhov ntswg, thiab lwm yam, thiab cov foob pob hluav taws yuav tsum raug txwv.

5. Kev ua haujlwm ib puag ncig sib txawv

Cov xim dej: cov pa roj carbon tsawg, kev tiv thaiv ib puag ncig, txuag hluav taws xob, qis VOC emissions.

Xim: muaj ntau cov kuab tshuaj organic, uas tsim kev puas tsuaj rau tib neeg kev noj qab haus huv.

6. Lwm yam khoom sib txawv

Cov xim pleev xim rau dej: Nws yog hom xim tshiab, cov xim pleev xim yog mos thiab nyias, qhov khawb kuj yog qhov phem dua li cov xim, thiab lub sij hawm qhuav yog qeeb, tab sis cov xim zaj duab xis muaj qhov ua tau zoo thiab muaj zog tiv thaiv huab cua. .

Xim: Cov khoom siv thev naus laus zis yog qhov paub tab, cov xim pleev xim yog puv thiab tawv, khawb kuj muaj zog, thiab lub sijhawm ziab yog luv.

Tom qab nyeem cov kev paub uas tau hais hauv tsab xov xwm no, kuv tau nkag siab txog qhov tsis zoo ntawm cov xim pleev xim dej.Cov xim pleev xim rau dej muaj cov kev xav tau siab ntawm kev tu cov txheej txheem ntawm kev tsim kho thiab cov khoom siv, vim tias qhov nro ntawm cov dej yog qhov loj.Yog tias nws tsis raug ntxuav hauv qhov chaw Txwv tsis pub, cov nyhuv yuav tsis zoo tshwj xeeb, yog li peb tuaj yeem xaiv raws li nws qhov tsis zoo, thiab peb kuj paub qhov txawv ntawm cov xim dej thiab xim.
