Cov yam ntxwv cuam tshuam rau kev siv PPGI steel kauj

Cov nyhuv anticorrosive ntawm lub tsev xim txheej cov khoom yog ua ke ntawm txheej, pretreatment zaj duab xis thiab txheej (primer, sab saum toj xim thiab rov qab xim), uas ncaj qha cuam tshuam rau nws cov kev pab cuam lub neej.Los ntawm anticorrosion mechanism ntawm cov xim txheej, organic txheej yog ib yam ntawm cov khoom sib cais, uas cais cov substrate los ntawm corrosive nruab nrab kom ua tiav lub hom phiaj ntawm anticorrosion.

 

Cov yam ntxwv cuam tshuam rau kev siv PPGI steel kauj

 

PE:polyester txheej rau galvanized steel muaj zoo adhesion, txheej ntawm steel phaj yog ib qho yooj yim rau kev molding, uas tsis muaj nqi thiab cov khoom, xim thiab luster xaiv Scope yog loj, nyob rau hauv lub dav ib puag ncig ncaj qha raug, nws lub neej corrosion mus txog 5-8 xyoo, tab sis nyob rau hauv ib puag ncig kev lag luam lossis thaj chaw muaj kuab paug, nws lub neej kev pabcuam yuav raug txo qis.

SMP:Txhawm rau muab kev ua si tag nrho rau cov yam ntxwv ntawm polyester txheej thiab txhim kho nws sab nraum zoov durability thiab lub teeb tuav, polyester txheej tau hloov kho rau hauv silicon hloov txheej los ntawm cov tshuaj txias los yog cov tshuaj tiv thaiv thermal.SMP muaj kev tiv thaiv zoo dua thiab kev tiv thaiv corrosion rau 10-12 xyoo, tab sis nws tus nqi yog me ntsis siab dua PE, thiab nws cov adhesion thiab molding zog yog phem dua PE.

HDP:HDP yog ib qho resin nrog siab molecular hnyav, tsawg dua polymer ceg saw, ruaj khov zog, tsis yooj yim rau photolication, yog li tsis yooj yim rau hmoov thiab gloss txo, HDP siv tib yam inorganic ceramic pigment li PVDF, cov khoom muaj zoo heev xim tuav, uv kuj, sab nraum zoov durability thiab anti-hmoov kev ua tau zoo, raug nqi.

SRP:Nws muaj kev tiv thaiv zoo heev rau resin degradation nyob rau lub sij hawm ntev tshav ntuj thiab kub ib puag ncig, zoo heev durability, tab sis siab hardness.

PVDF khoom:Vim tias PVDF cov khoom siv tshuaj lom neeg thiab cov khoom siv tshuaj lom neeg ntawm cov khoom siv muaj zog, yog li txheej txheej muaj corrosion kuj zoo heev thiab cov xim tuav, nyob rau hauv kev tsim kho kev lag luam nrog cov xim coated steel phaj txheej, yog cov khoom siab tshaj plaws, feem ntau hu ua "xim phaj huab tais".Nws cov molecule yog cov qauv loj thiab ncaj, yog li ntxiv rau cov tshuaj tiv thaiv, nws cov khoom siv hluav taws xob, uv tsis kam thiab kub tsis kam yog qhov zoo heev.Nyob rau hauv ib puag ncig, nws lub neej anticorrotion tuaj yeem ncav cuag 20-25 xyoo, tab sis tus nqi siab, tus nqi ntawm cov txheeb ze xim coated steel phaj kuj siab dua, nws cov luster thawj koom ruam tsuas yog tsis tshua muaj luster, muaj ntau yam kev txwv. cov xim xaiv (xim xim tsis tuaj yeem muab).
