Kugwiritsa ntchito Epoxy Topcoat mu Industrial Anticorrosion

Epoxy topcoat ndi ya mitundu iwiri ya epoxy resin topcoat, yomwe ili ndi mawonekedwe apadera a kukana, kukana, kukana kwamadzi, kukana kutsitsi kwa mchere komanso kukana kutentha (osapitirira 150 ° C). Ndizoyenera zipinda zapansi zamkati popanda kuwala kwa dzuwa Anticorrosive ndi zokongoletsera topcoat m'chilengedwe.

Kugwiritsidwa ntchito molumikizana ndi epoxy primer, filimuyi ndi yolimba komanso yosavala, imakhala ndi moyo wautali, ndipo imakhala ndi ntchito yabwino kwambiri pakukana madzi, kukana mafuta, komanso kukana mankhwala. Komabe, chifukwa cha zoletsa kutentha panthawi yomanga, kumanga kutentha kochepa sikungatheke. Monga utoto wamagulu awiri, ndizovuta kugwiritsa ntchito. Epoxy topcoat imakhala ndi vuto lakunja kwanyengo, imatha kufa ndikutaya gloss, imakhudza kukongoletsa, koma imakhala ndi mphamvu zochepa pachitetezo.

Zovala zambiri za epoxy zakhala zikugwiritsidwa ntchito ngati malaya apamwamba omwe safuna kumaliza kukongoletsa mkati mwamapangidwe amkati kapena m'nyumba. Chifukwa malowa sadzakhala poyera ndi dzuwa ultraviolet kunyezimira, palibe chifukwa chodandaula kuti ❖ kuyanika filimu adzakhala ufa.

Epoxy topcoat ndi yoyenera kuteteza mbiya, makina opanga mafakitale ndi zida, makina ndi magetsi, zida zachitsulo, zida zamakina, milatho, nsanja zam'mphepete mwa nyanja, zombo zam'madzi, chitetezo cha konkire, madera a m'mphepete mwa nyanja ndi zida zonyowa ndi zotentha ndi zitsulo zina ndi zina. -zitsulo pamwamba. Chovala chokongoletsera.

Chovala chapamwamba ndicho chophimba chomaliza chajambula, ndipo ndi gawo lomaliza lomwe limagwiritsidwa ntchito pokongoletsa khoma la nyumbayo. Zotsatira zonse pambuyo pokongoletsa zikuwonekera kudzera mumsewuwu. Choncho, pali zofunikira zapamwamba za zipangizo zomwe zimagwiritsidwa ntchito, osati kukhala ndi chroma yabwino ndi kuwala, komanso kukhala ndi kukana kwabwino kwa kuipitsidwa, kukalamba, kukana chinyezi, kukana nkhungu, ndi malo osaipitsa, otetezeka komanso opanda poizoni, Ayi. ngozi yamoto, kumanga kosavuta, kuyanika mwachangu kwa filimu yokutira, kuwala kwabwino ndi kusungidwa kwamtundu, kutulutsa bwino ndi zina zotero. Ndi ntchito zokongoletsa ndi chitetezo, monga mtundu, gloss, mawonekedwe, ndi zina zotero, ziyeneranso kugonjetsedwa ndi malo ovuta.

Utoto ukhoza kupanga mitundu itatu yomwazikana ndi madzi kudzera m'njira zosiyanasiyana zamadzi: ① kusungunuka m'madzi; ② mtundu wobalalika wa micelle; ③ emulsion. Epoxy resin palokha ndi thermoplastic liniya kapangidwe. Pambuyo pa kutentha, dziko lolimba limakhala lamadzimadzi, ndipo kukhuthala kwapamwamba kumasanduka kukhuthala kochepa. Pokhapokha atagwiritsidwa ntchito limodzi ndi wothandizira wochiritsa ndi wothandiza. Hardener). Chifukwa chake, dongosolo lamadzi la epoxy liyenera kukhala ndi madzi otulutsa epoxy resin ndi wothira madzi epoxy. Momwemonso, amatha kupanga mitundu itatu yobalalika madzi kudzera m'njira zosiyanasiyana zamadzi. Chifukwa chake, dongosolo la epoxy m'madzi lili ndi zophatikizira zochulukirapo (zongoyerekeza zimakhala ndi mitundu 9 ya mitundu yophatikizika ya morphological), komanso zimawonjezera zovuta kusankha. Panthawi imodzimodziyo, pogwiritsira ntchito ndondomeko yeniyeni, powonjezera kuchuluka kwa pigment, fillers, etc., kuti apititse patsogolo machitidwe a epoxy opangidwa ndi madzi, amaphimbanso zofooka komanso ngakhale zolakwika zazikulu za madzi. dongosolo epoxy, amene adzawonjezera kusatsimikizika ndi zovuta Kugonana. Siyani zovuta komanso zosavuta, tcherani khutu ku mawonekedwe a madzi opangidwa ndi epoxy resin ndi mawonekedwe a madzi opangidwa ndi epoxy kuchiritsa agent, panthawi imodzimodziyo, poyang'anira chiyambi cha madzi opangidwa ndi epoxy resin komanso kuwunika kwa madzi. epoxy resin kuti mukwaniritse kusankha kwachangu komanso kwabwinoko kachitidwe ka epoxy kamadzi Kuyika maziko a nyumba yayikulu.
