Polyvinyl Chloride (PVC) Powder Coatings – Develop, Application, Supply

Daim ntawv no tham txog kev txhim kho polyvinyl chloride (PVC) hmoov txheej hauv tsev thiab txawv teb chaws, qhia txog cov qauv yooj yim, kev npaj tshuab thiab kev ua haujlwm Performance index ntawm PVC hmoov coatings, thiab ua kom muaj kev taw qhia tsim nyog rau nws daim ntawv thov hauv kev tiv thaiv corrosion thiab kho kom zoo nkauj ntawm cov kav hlau.

Lus Qhia Tshab

Powder txheej yog ib yam ntawm 100% khoom hmoov. Nws txawv ntawm cov txheej txheem hnyav-raws li txheej thiab dej-soluble txheej, tsis yog cov kuab tshuaj los yog dej raws li qhov nruab nrab dispersion, tab sis nrog kev pab los ntawm huab cua ua ib qho nruab nrab dispersion. Yav dhau los decade, tsoom fwv hauv ntiaj teb los tsim cov coatings factories thiab cov lag luam los ntawm ib puag ncig kev ua qias tuaj, ntxiv dag zog rau cov kev txwv ntawm kev siv cov kuab tshuaj. Thaum kawg ntawm lub eighties nyob rau hauv Europe thiab lub tebchaws United States nyob rau hauv cov txheej txheem tsim, ntau lawm, kev tsim kho daim ntawv thov yog nruj me ntsis txwv tsis pub siv cov kuab tshuaj thiab emissions, tej qhov chaw ntawm lub tebchaws United States kuj nyob rau hauv daim ntawv ntawm cov kev cai lij choj tshaj tawm cov hnyav siv txwv txoj cai, cov kev cai ntawm ntau npaum li 66. cov khoom, thiab Europe thiab Tebchaws Meskas tau muab "peb E" lub hom phiaj:

(1) Ecology Hloov Kho
(2) Kev txuag hluav taws xob
(3) Kev Pab Nyiaj Txiag

Hauv cov ntsiab lus no, cov hmoov txheej txheej tau ntsib kev txhim kho sai vim lawv qhov tsis muaj kuab paug, kev siv cov khoom siv raw, thiab ntau yam zoo. Tshwj xeeb hauv Western Europe thiab North America, qhov kev loj hlob txhua xyoo ntawm cov hmoov coatings ncav cuag 10%. Ntxiv mus, nyob rau hauv xyoo tas los no, Tuam Tshoj kuj tau pom qhov kev loj hlob zoo kawg nkaus txhua xyoo ntawm 100% rau cov hmoov txheej.

Polyvinyl chloride (PVC) Powder Coatings tshwj xeeb tshaj yog nyiam los ntawm cov neeg siv vim lawv cov khoom zoo nkauj tshwj xeeb nrog rau huab cua thiab corrosion kuj. Tam sim no, PVC hmoov txheej yog siv dav hauv ntau qhov chaw xws li kev tiv thaiv cable nrog cov yeeb nkab steel, tshuaj tiv thaiv corrosion yeeb nkab, cov kav dej hauv cov kav dej, cov kav dej rau cov roj av thiab tshuaj lom neeg kev lag luam, cov paib txoj kev, teeb pom kev zoo, txoj kev loj guardrail thiab lwm yam.

Txheej Txheem Txhim Kho

1.Basic formula ntawm PVC hmoov txheej

PVC hmoov txheej yog ua los ntawm PVC resin raws li cov khoom siv hauv paus nrog plasticizer, stabilizer, muab tub lim thiab lwm yam khoom ntxiv. Cov qauv yooj yim yog qhia hauv Table (Dawb xim).

2.Kev npaj Technology ntawm PVC hmoov txheej

Txoj kev npaj ntawm PVC hmoov txheej, nws cov txheej txheem yog qhia nyob rau hauv daim duab.

3.Product Performance Analysis Test Results

Tom qab repeated kev tshawb fawb thiab kev tsim kho, kev sim, thiab piv nrog cov khoom siv txawv teb chaws, qee qhov kev ua tau zoo ntawm PVC hmoov txheej thaum kawg mus txog lossis txawm tias dhau qhov kev ua tau zoo ntawm cov khoom tuaj txawv teb chaws, saib lub rooj.

Daim ntawv thov ntawm PVC Hmoov Coated Steel Pipe

PVC hmoov txheej zaj duab xis yog semi-hard thermoplastic xeev. Piv nrog polyethylene, lub melting kub thiab decomposition kub sib txawv yog me me, yog li thaum siv yuav tsum xyuam xim rau qhov kub thiab txias thiab lub sij hawm. Vim nws cov adhesion tsis zoo, ua ntej dipping, feem ntau yuav tsum tau coated nrog ib txheej ntawm primer kom cov adhesion ntawm txheej.

1.Qhov tseem ceeb ntawm cov txheej txheem

• PVC hmoov txheej cov khoom muaj xws li: cov khoom siv kho kom zoo nkauj sab hauv tsev thiab cov ntaub ntawv tsis muaj dej tsis zoo, cov khoom siv tshuaj lom neeg, cov plag tsev, cov ntaub ntawv ntim cov yeeb yaj kiab, lub vaj hose thiab cov rwb thaiv tsev.
• Cov txheej txheem ua tau txais kev sib tov qhuav, txhaj tshuaj molding, extrusion hollow tshuab moulding, calendering, thiab fluidized txaj poob.
• Nplaim retardant (ntxiv nplaim retardant)
• Dej thiab tshuaj tiv thaiv, zoo aging kuj.

2.Main siv txoj kev thiab daim ntawv thov ntau yam

PVC hmoov txheej yog tsuas yog siv nyob rau hauv hlau mesh, txias cia shed, steel rooj tog, steel yeeb nkab thiab lwm yam. Txheej txheej txheej yog feem ntau raws li hauv qab no:

(1) Kev kho ua ntej: kev kho phosphate - tshem tawm xeb, phosphating.
(2) Primer txheej: Dip lub primer, tom qab ziab, lub thickness ntawm primer zaj duab xis yog 5-10μm,
(3) electrostatic txau los yog fluidized txaj dipping.
4. preheating kub: 230-290 ℃, 10min, zaj duab xis thickness: 500um;
Los yog 290 ℃, 5min tsis preheating, zaj duab xis thickness 200um.

PVC coated steel yeeb nkab yog pab tau nyob rau hauv petrochemical anti-corrosion, pab tau nyob rau hauv txoj kev loj guardrail, pab tau nyob rau hauv tus ncej, tom qab ntau xyoo ntawm daim ntawv thov kev tshwm sim qhia tau hais tias. PVC txheej dej tsis kam, atmospheric aging kuj yog qhov zoo, feem ntau muaj rau ntau tshaj 15 xyoo, tshem tawm cov teeb meem ntawm cov xim txhuam hniav feem ntau, kev sib piv ntawm nws tus nqi qis, siv tshuaj tiv thaiv corrosion, kuj tseem siv tau ntau tshaj tsib xyoos, rau tus neeg siv los daws qhov teeb meem los tiv thaiv corrosion.
