Xim rau galvanized hlau rau sab nraum zoov ua haujlwm: hom thiab nta

Hauv kev tsim kho, niaj hnub siv hlau yog siv ntau heev. Nws tau los ua nrov vim nws txoj kev ntseeg zoo thiab kev ua haujlwm. Tab sis cov zinc txheej tau nws cov teeb meem, qhia rau hauv kev tsis haum rau corrosion. Cov ntaub ntawv ho tsis yog ntau npaum li cas rau cov nyhuv li cov hlau, tab sis, yog tias koj xav mus ua haujlwm ntev, nws yuav tsum tau them nrog ib qho xim tshwj xeeb.

Lub ntsiab yam xim galvanizing

Yog tias koj xav tau xim rau cov xim hlau rau sab nraum zoov, ces koj yuav tsum tau nrog qee yam ntawm cov coatings. Lawv yog:

• Acrylic;
• Vinyl;
• Alkyd;
• Roj Hmab.

Acrylics feem ntau yog ua raws li cov organic solvents, ntawm qhov muag kuj tuaj yeem pom cov dej-dispersion compositions. Ntawm cov khoom xyaw lawv muaj cov tshuaj tiv thaiv corrosion. Siv cov acrylic xim thiab cov khoom ua vanish, nws yog ib qhov ua tau los tsim ib txheej matte rau ntawm qhov chaw. Lub ntsiab zoo ntawm cov sib xyaw ua ke no: kev ntseeg tsis tau zoo rau sab nraud influences, ultraviolet, zoo heev adhesion, zoo heev dej-repellent zog, durability thiab luv nqi.

Txheej txheem cej luam ntawm cov nta ntawm alkyd paints galvanizing

Cov xim rau cov xim hlau sab nrauv rau sab nraum zoov ua haujlwm yog alkyd. Yog hais tias koj sib piv nrog cov khoom siv saum toj no, ces nrog kev pab los ntawm thawj ib qho koj tuaj yeem tsim muaj glossy txheej. Hauv cov txheej txheem tsim, kev siv tshuaj tiv thaiv kom tsis muaj zog. Ntawm lwm yam, cov xim no muaj kev ua tau zoo. Nyob rau hauv ntau cov kev lag luam niaj hnub, alkyd compounds yuav pom tau tias yuav siv tau rau hauv cov chaw muaj kev lag luam thiab marine climates.

Txheej txheem cej luam ntawm cov yeeb yam ntawm cov xim pleev xim rau kev sib daj sib deev

Xim rau galvanized hlau rau sab nraum zoov ua haujlwm kuj tseem yuav vinyl. Tsis ntev los no, nws pib nce qhov chaw, uas yog vim qee qhov ntawm nws cov khoom. Cov xim muaj cov huab cua tsis kam thiab cov cwj pwm zoo nrog cov teebmeem kub.

Nyob rau saum npog nrog ib cov khoom, qhov kub tau tas li tau nce mus txog 70 ° C, mus ib ntus ntawm qhov kub tau nce mus txog 90 ° C. Txawm li cas los xij, lub hau yas kuj muaj qee qhov tsis zoo, uas tau hais tawm hauv cov nqi siab. Tus nqi raug cai los ntawm ib co kev zoo ntawm kev ua haujlwm ntawm kev ua haujlwm.

Txheej txheem cej luam ntawm cov nta roj hmab xim galvanizing

Cov xim rau galvanized hlau rau sab nraum zoov ua haujlwm kuj tau hais nrog lub roj hmab txheej, uas yog ua los ntawm acrylic. Ntawm qhov txawv cov yam ntxwv - siab elasticity. Tom qab ziab, cov txheej txheej saum toj kawg nkaus ntawm cov khoom siv yuav zoo li roj hmab, ua tsaug rau qhov no tsis yog qhov phem tshaj plaws rau ntawm cov hluav taws xob, xws li pob.

Xws li cov xim rau cov hniav hlau yog qhov txawv ntawm lawv cov nplaim, cov tshuaj ua haujlwm, huab cua zoo, kev phooj ywg zoo thiab cov khoom zoo nkauj.

Tshaj tawm xim ib lub ru tsev ntawm zinced hlau

Yog hais tias koj xav tau pleev xim rau galvanized hlau, tshaj pleev xim lub-ru tsev, koj yuav tsum xav txog. Feem ntau cov coatings hnub no tuaj yeem raug hu ua: acrylic dye, oil paints, as well as compositions nrog cov khoom los tiv thaiv corrosion. Rau tej qhov chaw, tshwj xeeb dyes yuav tsum tau siv rau vim li cas nyob rau hauv galvanizing lub saum npoo yog ntau passive tshaj cov pa hlau. Yog li ntawd, cov xim yuav tsum tau xaiv noj mus rau hauv tus account lub siab elasticity.

Thaum xaiv ib cov xim ntawm cov chaw uas muaj teeb meem, cov kws qhia tawm tswv yim kom them sai sai rau cov pob zeb "Acrylic matt dye" Cicrol ", uas muaj cov khoom nplaum loj thiab cov khoom siv zoo heev ntawm anticorrosion. Ntawm qhov zoo ntawm no xim thiab cov khoom ua kom muaj roj vanish yog: tsis kam mus rau qhov atmospheric influences, zoo siab kam rau qis kub thiab noo noo. Cov xim no tom qab ziab sai sai, qaug tshuaj ultraviolet tsis hlawv tawm thiab muaj dej-tiv thaiv khoom. Thov nws kom qhuav thiab huv si nrog ib tug sprayer, rau cov menyuam los yog txhuam. Yog hais tias tsim nyog, qhov muaj pes tsawg leeg yuav tsum tau diluted nrog P646 hnyav los yog butyl acetate. Xws li kev tiv thaiv kev ua kom ho muaj lub neej ntawm lub ru tsev.

Kev txhim kho ntawm cov xim "Vajvoog"

Qhov xim anticorrosive rau galvanized hlau yog ib tus qauv txha hniav, uas yog ua los ntawm acrylic resins thiab polymer additives. Raws li cov ntsiab lus ntxiv yog cov organic solvents. Raws li cov neeg muas zaub, qhov sib xyaw kom haum muaj ib qho siab zais lub hwj chim ntawm qhov chaw mus rau xim.

Tiv thaiv kom sib tov muaj peev xwm ua tau los ntawm kis tau cua ntsev. Cov neeg tau txais kev pom zoo hais tias qhov kev yoojyim no yog yooj yim los siv, muaj cov roj ntsha muaj peev xwm thiab tsim nyog tsis yog rau cov hlua hluav taws xob, tab sis cov kua dej, cov kav dej, cov kav hlau, cov cav, corrugated board, iron thiab galvanized iron.

Daim ntawv thov ntawm qhov sib tov yuav tsum tau nqa tawm ntawm qhov chaw uas tau muab ntxuav los ntawm xeb, thiab xylene los yog ethyl acetate yuav muab siv los ua kuab tshuaj yog tias tsim nyog.

Cov neeg tau txais kev pab yuav tsum tau ua hauj lwm ntawm qhov kub thiab txias ntawm -10 rau +50 ° C. Kev ntim kom qhuav yuav tsum tos txog 18 teev, qhov no yog qhov tseeb yog tias qhov kub ntawm huab cua sab nraud yog + 20 ° C.

Xaus

Daim ntawv thov ntawm ib lub xim tshwj xeeb xim nyob rau ntawm qhov chaw saum npoo dej yuav tiv thaiv nws ntawm qhov tsis zoo ntawm qhov chaw sab nraud. Txawm li cas los xij, yuav pib cov kws txawj ua haujlwm no tsuas yog ib lub xyoos tom qab tiav qhov kev teeb tsa ntawm cov vov tsev.

Thaum lub sij hawm no, cov cua yuav npaj lub substrate rau qhov uas tseg, ntxuav cov xeb thiab ua rau lub qhov ntxhib me ntsis. Yog tias koj xav ua hauj lwm nyob rau hauv ib lub sij hawm luv luv, ces koj tuaj yeem npaj qhov chaw koj tus kheej, tab sis qhov no, koj yuav tsum sim tsis txhob lwj lub nyias txheej ntawm galvanizing.
