Kupera ndeye kushandisa dzimwe nzira kuderedza kupenya kwenzvimbo yekuputira.
1. kutsakatika musimboti
Yakasanganiswa nemagadzirirwo emufirimu wepamusoro gloss uye zvinhu zvinokanganisa kupenya, vanhu vanotenda kuti kutsakatika kushandisa nzira dzakasiyana kuparadza kutsvedzereka kwefirimu, kuwedzera pamusoro peiyo micro roughness yefirimu, uye kuderedza kuratidzwa kweiyo firimu. kuchiedza.Inogona kukamurwa kuva kupera kwenyama uye kupera kwemakemikari.Nheyo yekusangana kwemuviri ndeye: wedzera matting agent kuti iite nzvimbo yekuputira isina kuenzana mumafirimu ekugadzira, kuwedzera kupararira kwechiedza uye kuderedza kufungisisa.Kupera kwemakemikari kuwana kupenya kwakaderera nekuunza zvimwe zvimiro zvinotora mwenje kana mapoka senge polypropylene yakabatanidzwa zvinhu muUV coatings.
2. nzira yekutsakatika
Matting agent, mune yanhasi UV coating industry, vanhu vanowanzo shandisa nzira yekuwedzera matting agent.Pane kunyanya zvinotevera zvikamu:
(1) Sipo yesimbi
Sipo yesimbi imhando yekumisikidza agent inowanzoshandiswa nevanhu vekutanga.Inonyanya kuve imwe simbi stearate, yakadai sealuminium stearate, zinc stearate, calcium stearate, magnesium stearate uye zvichingodaro.Aluminium stearate ndiyo inonyanya kushandiswa.Nheyo yekuparara kwesipo yesimbi inobva pakusapindirana kwayo nezvikamu zvekuputira.Inoturikwa muhuputi ine zvimedu zvakanaka kwazvo, izvo zvinogoverwa pamusoro pechifukidzo kana firimu rinoumbwa, zvichiita kuti micro roughness pamusoro pekuputira uye kuderedza kuratidzwa kwechiedza pamusoro pechifukidzo kuti chibudirire. chinangwa chokutsakatika.
(2) Wakisi
Wax inhengo yepakutanga uye inonyanya kushandiswa zvakanyanya, inova yeorganic suspension matting agent.Mushure mekugadzirwa kwekuputira, nekuputika kwezvinonyungudutsa, wakisi mufirimu yekuputira inoparadzaniswa uye yakaturikwa pamusoro pefirimu yekuputira nemakristasi akanaka, zvichiita mutsara wehupamhi hwekuparadzira chiedza uye kutamba basa rekutsakatika.Semumiriri wemateti, wakisi iri nyore kushandisa, uye inogona kupa iyo firimu kunzwa kwakanaka kwemaoko, kusamira kwemvura, kunyorova uye kupisa kwekudzivirira, uye kushomeka kwemavara.Zvisinei, mushure mokunge wax layer yaumbwa pamusoro pefirimu pamusoro, ichadzivirirawo kuparara kwe solvent uye kupindira kweokisijeni, inokanganisa kuomeswa uye kudzorerazve firimu.Maitiro ekusimudzira mune ramangwana ndeyekugadzira polymer wax uye silica kuti uwane yakanakisa kutsakatika maitiro.
(3) Faindi dzinoshanda
Mavara emuviri, akadai se diatomite, kaolin uye fumed silica, faindi dzinoshanda dzinoshandiswa zvakanyanya sema matting agents.Ivo ndeve inorganic yakazadzwa matting agents.Kana firimu racho raoma, tunhu twawo twudiki twunoumba twunhu twudiki twunenge twusina kukwasharara pamusoro pemufirimu kuderedza kupenya kwechiedza uye kuwana chimiro cheMat.Iyo matting mhedzisiro yerudzi urwu rwemating agent inorambidzwa nezvakawanda zvinhu.Kutora silica semuenzaniso, kana ichishandiswa semumiriri wemateti, mhedzisiro yayo yekuisa ichakanganiswa nezvinhu zvakadai sevhoriyamu yepore, avhareji saizi yechikamu uye particle size kugovera, yakaoma firimu ukobvu uye kana chidimbu chepamusoro chakarapwa.Ongororo dzinoratidza kuti kutsakatika kwe silica dioxide ine hombe pore vhoriyamu, yunifomu particle saizi kugovera uye kuenzanisa particle size ine yakaoma firimu ukobvu zviri nani.
Pamusoro pemhando nhatu dziri pamusoro apa dzeanowanzo shandiswa matting ejenti, mamwe oiri akaoma, senge tung oiri, anogona zvakare kushandiswa semameta maajenti muUV majasi.Iyo inonyanya kushandisa iyo yakakwirira reactivity ye conjugated double bond ye tung oil kuita kuti pasi pefirimu ive neoxidation yakasiyana uye cross-linking speeds, kuitira kuti pamusoro pefirimu ive isina kuenzana kuti iwane matting effect.
