Polyester Resin Hmoov Txheej
Kev Taw Qhia General:
Nws yog tsim los ntawm carboxyl polyester cob, pigment muab tub lim thiab TGL ua tus neeg sawv cev kho, nrog huab cua tsis kam thiab UV tsis kam. Zoo mechanical zog, siab hardness, khawb kuj, corrosion kuj; Cov cuab yeej zoo leveling, zaj duab xis yog qhov yooj yim tsis muaj pinholes, shrinkage qhov thiab lwm yam tsis xws luag; Nws tuaj yeem siv rau cov khoom siv hlau sab nraum zoov xws li lub tshuab cua txias, lub teeb sab nraum zoov thiab cov teeb ci.
Khoom Series:
muab cov ntsiab lus tseem ceeb (80% saum toj no), semi-light (50-80%), iav dawb (20-50%) thiab tsis muaj teeb (20% hauv qab) cov khoom lossis raws li qhov yuav tsum tau ua
Lub cev muaj zog:
Lub ntiajteb txawj nqus (g / cm3, 25 ℃): 1.2-1.7
Particle loj faib: 100% tsawg dua 100 micron (Nws tuaj yeem hloov kho raws li cov kev cai tshwj xeeb ntawm kev pleev xim)
Kev tsim kho:
Pretreatment: qhov saum npoo yuav tsum tau ntxuav kom huv si kom tshem tau cov roj thiab xeb. Daim ntawv thov ntawm hlau series phosphating los yog siab dua tus qauv zinc series phosphating tuaj yeem txhim kho kev tiv thaiv corrosion ntxiv.
Curing hom: phau ntawv los yog siv phom zoo li qub
Curing tej yam kev mob: 190-200 ℃ (workpiece kub), 10 feeb

Nco tseg:
1.Cov kev ntsuam xyuas saum toj no siv 0.8mm tuab txias-kuav los tiag steel daim hlau nrog txheej txheej thickness ntawm 30-40 microns tom qab txheej txheem pretreatment.
2.Qhov Performance index ntawm cov txheej saum toj no yuav txo qis me ntsis nrog qhov txo qis ntawm gloss.
Kev pab them nqi nruab nrab:
8-11 sq.m./kg; zaj duab xis thickness 70 microns (xws li 100% hmoov txheej siv tus nqi)
Packing thiab thauj:
cartons yog lined nrog polyethylene hnab, nqa nyhav yog 20kg; Cov ntaub ntawv tsis muaj kev phom sij tuaj yeem thauj tau ntau txoj hauv kev, tab sis tsuas yog kom tsis txhob raug tshav ntuj ncaj qha, ya raws thiab cua sov, thiab tsis txhob sib cuag nrog cov tshuaj lom neeg.
Kev Cia Siab:
Ntxuav, qhuav, ventilated, deb ntawm lub teeb, chav tsev kub hauv qab 30 ℃, thiab yuav tsum tau insulated los ntawm hluav taws qhov chaw, deb ntawm tshav kub qhov chaw.Lub sij hawm cia zoo yog 6 lub hlis txij li hnub tsim khoom. Tom qab lub sijhawm khaws cia, nws tuaj yeem rov tshuaj xyuas thiab siv dua yog tias cov txiaj ntsig tau raws li qhov xav tau. Tag nrho cov ntim yuav tsum tau rov ntim dua thiab xa rov qab mus rau lawv qhov ntim qub tom qab siv.
Nco tseg:
Tag nrho cov hmoov yog khaus rau hauv lub ntsws, yog li tsis txhob nqus cov hmoov thiab chav los ntawm kev kho. Sim zam kev sib cuag ncaj qha ntawm daim tawv nqaij thiab hmoov txheej. Ntxuav cov tawv nqaij nrog dej thiab xab npum thaum xav tau kev sib cuag. Yog tias qhov muag tshwm sim, ntxuav daim tawv nqaij tam sim nrog dej huv thiab nrhiav kev kho mob tam sim ntawd. Plua plav txheej thiab hmoov particle deposition yuav tsum tau zam rau ntawm qhov chaw thiab cov ces kaum tuag. Cov khoom me me me me yuav ignite thiab ua rau tawg nyob rau hauv hluav taws xob zoo li qub. Tag nrho cov khoom siv yuav tsum tau ua hauv av, thiab cov neeg ua haujlwm tsim kho yuav tsum hnav cov khau tiv thaiv zoo li qub kom cov av tiv thaiv hluav taws xob zoo li qub.
