Plasticizers nyob rau hauv cov txheej txheem txheej
Plasticizers yog siv los tswj cov txheej txheem tsim cov yeeb yaj kiab ntawm cov txheej txheem raws li lub cev kom qhuav zaj duab xis tsim cov ntaub ntawv. Kev tsim cov yeeb yaj kiab tsim nyog yog qhov tseem ceeb txhawm rau ua kom tau raws li qhov xav tau ntawm cov txheej txheem tshwj xeeb xws li cov yeeb yaj kiab qhuav, substrate adhesion, elasticity, ua ke nrog cov qib siab hardness tib lub sijhawm Plasticizers ua haujlwm los ntawm kev txo cov zaj duab xis tsim kub thiab elasticize txheej; plasticizers ua hauj lwm los ntawm embedding lawv tus kheej ntawm cov chains ntawm polymers, sib nrug los ntawm lawv (nce "dawb ntim"), thiabNyeem ntxiv…
Qee cov ntsiab lus kom paub qhov zoo ntawm cov hmoov txheej hmoov
Kev Taw Qhia Sab Nraud Sab Nraud: 1. Tes Xav: Yuav tsum xav tias silky du, xoob, ntab, du ntau dua ntawm cov hmoov, qhov zoo ntawm qhov tsis sib xws, hmoov zoo li ntxhib thiab hnyav, tsis zoo, tsis yooj yim txau, hmoov poob ob zaug ntxiv nkim. 2.Volume: Qhov loj ntawm lub ntim, qhov tsawg dua ntawm cov hmoov txheej txheej, cov nqi siab dua, qhov zoo ntawm cov hmoov txheej txheej.

Ib puag ncig zoo ntawm hmoov txheej txhais tau tias txuag nyiaj ntau
Niaj hnub no qhov kev txhawj xeeb ntawm ib puag ncig yog qhov tseem ceeb ntawm kev lag luam hauv kev xaiv lossis kev ua haujlwm ntawm kev ua tiav. Qhov zoo ntawm ib puag ncig ntawm hmoov txheej-tsis muaj VOC teeb meem thiab qhov tseem ceeb tsis muaj pov tseg- tuaj yeem txhais tau tias txuag nyiaj ntau hauv cov nqi tiav. Raws li cov nqi hluav taws xob nce ntxiv, lwm qhov zoo ntawm cov hmoov txheej ua qhov tseem ceeb dua. Yog tias tsis xav tau cov kuab tshuaj rov qab, cov tshuab lim dej tsis tas yuav tsum tau ua, thiab huab cua tsawg dua yuav tsum tau txav mus los, ua kom sov, lossis txias, uas tuaj yeem ua rau muaj txiaj ntsig zoo.Nyeem ntxiv…
Sab nrauv architectural gloss coatings pigment xaiv
Muaj ob hom ntawm TiO2 pigments: cov uas enamel qib ua yeeb yam hauv qab Critical Pigment Volume Concentration (CPVC), uas sib haum rau gloss thiab semi gloss hmoov txheej, thiab cov kev txhim kho qhov sib txawv rau saum toj no CPVC coatings daim ntaub ntawv (pav nam). Sab nrauv architectural gloss coatings pigment xaiv yog raws li ib tug zoo tshuav nyiaj li cas ntawm cov khoom txuam rau nruj Particle Loj Distribution uas enables cov khoom los muab superior sab nrauv siab gloss.Nyob rau hauv dav xaiv ntawm pigments, lub ntsiab sawv daws yuav rau daim ntawv thov noNyeem ntxiv…
Yuav Ua Li Cas Hmoov Txheej
Yuav ua li cas cov hmoov txheej: pre-kho - ziab kom tshem tawm dej - txau - Kos - ci - kos - Tiav. 1.Cov yam ntxwv ntawm cov hmoov txheej tuaj yeem muab kev ua si tag nrho kom ntev lub neej txheej kom tawg cov xim pleev xim ua ntej nruj nreem ua ntej kho. 2.Spray, tau pleev xim rau kom tag nrho hauv av thiaj li yuav ua rau kom cov hmoov txheej ntawm puffing. 3.Qhov loj defects yuav tsum tau pleev xim rau, coated kos conductive putty, thiaj li yuav xyuas kom meej lubNyeem ntxiv…
Cov txheej txheem yog siv los ntes overspray thaum hmoov txheej
Peb txoj kev yooj yim yog siv los ntes cov tshuaj txau hmoov txheej hmoov: Cascade (tseem hu ua dej ntxuav), Baffle, thiab Media pom. Ntau lub tsev ntim tshuaj niaj hnub no suav nrog ib lossis ntau dua ntawm cov txheej txheem ntawm kev ntes hauv kev siv zog los txhim kho ove.rall tshem tawm efficiency. Ib qho kev sib xyaw ua ke ntau tshaj plaws, yog lub rooj muag khoom cascade style, nrog rau ntau theem xov xwm pom, ua ntej lub tso pa tawm, lossis ua ntej VOC tswj tshuab zoo li RTO (regenerative thermal oxidizer).
