Upende wokugqwala

I-anti-rust paint iwuhlobo lwento edlala indima yokuqeda ukugqwala, ivimbela ukugqwala kwensimbi futhi ithuthukise umphumela wokuvikela wefilimu kapende endaweni yensimbi. Indima kapende omelene nokugqwala ingahlukaniswa izigaba ezimbili: ukulwa nokugqwala ngokomzimba namakhemikhali okulwa nokugqwala, lapho upende lwamakhemikhali olwa nokugqwala lungahlukaniswa lube ukuvimbela ukugqwala kanye nohlobo lwesibili lwesenzo se-electrochemical. Izinto ezidlala indima yokuvimbela ukugqwala ikakhulukazi zifaka impushana ebomvu ebomvana, impushana ebomvu yensimbi, impushana yensimbi eyinhlanganisela ye-titanium, i-aluminium tripolyphosphate zinc powder nokunye. Njengamanje, upende ophikisana nokugqwala usetshenziswa ikakhulukazi ezingxenyeni ezilwa nokugqwala, kanti izindleko ze-anti-corrosion coatings zifinyelela ku-6% -8.5%.

Uyini umehluko phakathi kwe-Anti-rust paint nopende?

Upende ovikela ukugqwala uwuhlobo lukapende olungavikela izinto ezingaphezulu kwensimbi ekugqwaleni kwamakhemikhali noma kwe-electrochemical emkhathini, emanzini olwandle, njll. Upende wemvelo nowamakhemikhali wokulwa nokugqwala, njengobomvu bensimbi, impushana ye-aluminium, upende we-graphite ovimbela ukugqwala, umthofu obomvu, upende ophuzi we-zinc ophuzi nokunye.

I-Paint iyingxube yengxube yamakhemikhali ehlanganisa ngokuqinile ingaphezulu lezinto, ivikela, ihlobise, amamaki nezinye izinjongo ezikhethekile, futhi yakha ifilimu eqinile enamathela ngokuqinile ebusweni bezinto futhi inamandla athile nokuqhubeka.

1. Imisebenzi ehlukene:

I-anti-rust paint inezindawo zokulwa nokugqwala kanye ne-anti-rust, ifilimu iqinile, isebenza kahle kakhulu, futhi ukuqina kuphakeme kunokupenda okuvamile. Upende ovamile awunawo umsebenzi wokulwa nokugqwala, ngoba impahla yefilimu kapende evamile i-alkyd resin, ngokusebenzisa i-oxidation nokomisa, ubulukhuni obumpofu, igebe lebanga lokunamathela.

2. Impilo yesevisi ehlukile:

I-anti-rust paint ingasetshenziswa iminyaka engu-5-8 uma kuqhathaniswa. Upende ojwayelekile uvame ukusetshenziswa ngaphandle cishe iminyaka emi-3. Ngemuva kweminyaka emibili noma emithathu, kulula ukuwa, ukufiphala kanye nempushana.

3. Izinhlobo ezahlukene:

Upende ovimbela ukugqwala: upende we-phenolic anti-rust, upende we-alkyd ovimbela ukugqwala (obomvu bensimbi, ompunga, obomvu), upende werabha one-chlorinated ovimbela ukugqwala, upende we-epoxy ovimbela ukugqwala (upende ovimbela ukugqwala we-zinc phosphate, upende obomvu womthofu ovimbela ukugqwala, upende ocebile we-zinc ovimbela ukugqwala, upende obomvu wensimbi ovimbela ukugqwala), njll.

Upende: Izinhlobonhlobo ezicebile zopende, upende ophikisana nokugqwala nawo uwuhlobo lukapende, ngaphezu kopende luhlanganisa nopende wokhuni, upende waphansi, upende wangaphandle odongeni, upende wamatshe, upende onemibala eminingi, upende we-aluminium alloy, upende ongashi, upende we-latex nokunye.

Izikhombisi-ndlela eziyisishiyagalombili zokuthuthukiswa kwesikhathi esizayo kopende ophikisana nokugqwala

Okokuqala, ukuthuthukiswa kwamanzi-based anti-rust primer kanye nopende ophezulu wezakhiwo zensimbi.

I-primer elwa nokugqwala esekwe emanzini kufanele ixazulule ukukhungatheka kwe-substrate "i-flash rust" kanye nokungazweli kahle kwamanzi, futhi ukukhuphuka kwamanye ama-emulsion amasha angenayo i-emulsifier kuye kwathuthukisa ngokuyisisekelo isihloko sawo sokumelana namanzi, futhi ikusasa kufanele ligxile ekuxazululeni izinkinga zomsebenzi wokwakha kanye nomsebenzi wokufaka isicelo. Njenge-topcoat, ikakhulukazi ukuthuthukisa umhlobiso wayo nokuqina ngaphansi kwesimo sokuqinisekisa umsebenzi wokuvikela.

Okwesibili ukuthuthukisa uchungechunge lokuqukethwe okuqinile okuphezulu nopende ongancibiliki wokugqwala.

Ukumba, amapulatifomu angasogwini kanye namaphrojekthi amakhulu okulwa nokugqwala emsebenzini wokulwa nokugqwala okuhlala isikhathi eside wezidingo zokumboza kuyaphuthuma, imakethe yamanje ngokuyisisekelo ingamabhizinisi angaphandle kanye nemikhiqizo evela kwamanye amazwe ehlala abantu. Imikhiqizo yaseChina ikakhulukazi isezingeni lobuchwepheshe, amandla ezomnotho, uhlelo lokuqinisekisa ikhwalithi kanye nesithunzi somkhiqizo kanye negebe eliphelele lamandla namazwe angaphandle, kunzima ukungena emakethe. Kuze kube manje, okokuqala, kufanele kwenziwe imizamo ekuthuthukisweni kwezobuchwepheshe, ikakhulukazi ukuthuthukiswa kwe-pigment primer engenawo umthofu ne-chromium-free, okungukuthi, esekelwe ku-zinc phosphate kanye ne-aluminium tripolyphosphate anti-rust primer.

Okwesithathu ukuthuthukisa i-primer esekelwe emanzini ecebile nge-zinc.

I-primer ecebile nge-zinc ephilayo kanye ne-primer ecebile nge-zinc esekelwe emanzini ingezinye zezinto ezisebenza isikhathi eside, kodwa ziyi-coatings esekelwe ku-solvent. I-primer esekelwe emanzini ecebile nge-zinc ene-modulus potassium silicate ephezulu njengoba impahla eyisisekelo iyimbobo ephezulu esebenzayo yokulwa nokugqwala evivinywa umkhuba futhi inamandla okuthuthukiswa.

Okwesine ukuthuthukiswa kwesishintshi sokushisa esilapha ukushisa okumelana nokugqwala.

Abashintshi bokushisa badinga izambatho eziphikisana nokugqwala ezinokumelana nokushisa okuphezulu kanye ne-thermal conductivity, futhi i-epoxy amino coating esetshenziswa njengamanje idinga ukuphulukiswa ku-120 ° C futhi idinga ukumbozwa okuningi, okungeke kusetshenziswe kumadivayisi amakhulu.

Okwesihlanu ukuthuthukisa i-coating engelapheka ekamelweni lokushisa futhi kulula ukuyisebenzisa.

Iphuzu eliyinhloko ukuthola ibhalansi engcono kakhulu phakathi komsebenzi wokuvimbela ukugqwala, umsebenzi wokudlulisa ukushisa kanye nomsebenzi wokwakha we-coating.

Okwesithupha ukuthuthukiswa kwe-flake anti-rust coating.

I-Mica iron oxide (MIO) inokumelana okuhle kakhulu kwe-dielectric, ukumelana nokuguga komkhathi nomsebenzi wokuvimba, futhi isetshenziswa kabanzi njenge-primer kanye nopende ophezulu eNtshonalanga Yurophu.

Okwesikhombisa, ukuthuthukiswa kochungechunge lwenjoloba ene-chlorine ye-anti-rust coating substitutes.

Ngenxa yokuthi irabha ene-chlorine iyingxenye eyodwa, ukwakhiwa kulula, ukumelana kwamanzi, ukumelana nowoyela, ukumelana nokuguga komkhathi kuhle kakhulu, kusetshenziswe kabanzi ekwakheni imikhumbi, ukuvimbela ukugqwala kwezimboni kanye neminye imikhakha, kunemakethe ebanzi e-China. Nokho, ngenxa yokuthi ukukhiqizwa kwenjoloba ekloriniwe kusebenzisa i-CC1 njengesincibilikisi, ungqimba lwe-ozone luyabhujiswa.

Okwesishiyagalombili ukuthuthukiswa kwezinto ezivimbela ukugqwala kwe-organic modified inorganic.

Eminyakeni yamuva, ukusetshenziswa emulsion eziphilayo ukhonkolo modified ukuthuthukisa amandla ayo, ukumelana medium, kabanzi enamathela ezimbonini floor. Phakathi kwazo, i-emulsion yamanzi e-epoxy (noma i-epoxy esekelwe ku-solvent) ithuthukisa esheshayo, ebizwa ngokuthi i-polymer cement.

Mayelana NATHI

Inkampani yethuibilokhu ibambelele "'kusayensi nobuchwepheshe, ikhwalithi kuqala, ukwethembeka nokwethembeka , ukusetshenziswa ngokuqinile kwe-ls0900l:.2000 uhlelo lokuphatha ikhwalithi yamazwe ngamazwe.Ukuphathwa kwethu okuqinile kobuchwepheshe bokusungula, isevisi yekhwalithi yenza ikhwalithi yemikhiqizo, yazuza ukuqashelwa kweningi labasebenzisi.Njengemboni ejwayelekile futhi eqinile yamaShayina, singanikeza amasampula kumakhasimende afuna ukuthenga, uma udinga upende ophikisana nokugqwala, sicela usithinte.
