Wothandizira
mankhwala katundu
Malinga ndi kapangidwe kake ka mankhwala, mtundu uwu wowongolera uli ndi magulu atatu akulu: acrylic acid, organic silicon ndi fluorocarbon.Leveling agent ndi chothandizira chothandizira chomwe chimagwiritsidwa ntchito nthawi zambiri, chomwe chingapangitse kuti zokutira zikhale filimu yosalala, yosalala komanso yofananira poyanika.Kodi bwino kuchepetsa padziko mavuto ❖ kuyanika madzi, kusintha ake kusanja ndi chifanane wa gulu la zinthu.Zitha kusintha permeability wa njira yomaliza, kuchepetsa kuthekera kwa mawanga ndi zolembera pamene akutsuka, kuonjezera kuphimba, ndi kupanga filimu yunifolomu ndi zachilengedwe.Makamaka surfactants, organic solvents ndi zina zotero.Pali mitundu yambiri ya ma agent, ndipo mitundu yoyezera yomwe imagwiritsidwa ntchito muzopaka zosiyanasiyana siyofanana.Zosungunulira zotentha kwambiri kapena ma cellulose a butyl zitha kugwiritsidwa ntchito popangira zosungunulira.M'madzi - pomaliza kumaliza wothandizila ndi surfactants kapena polyacrylic acid, carboxymethyl cellulose
Chiyambi cha malonda ndi mawonekedwe ake
Ma leveling agents amagawidwa m'magulu awiri.Mmodzi ndi kusintha filimu mamasukidwe akayendedwe ndi kusalaza nthawi ntchito, mtundu uwu wa kusalaza wothandizila makamaka ena mkulu otentha mfundo zosungunulira organic kapena zosakaniza, monga isoporone, diacetone mowa, Solveso150;Winawo ndikusintha mawonekedwe a filimu kuti agwire ntchito, anthu wamba adanenanso kuti wothandizira nthawi zambiri amatengera mtundu wamtunduwu.ZINTHU ZONSE ZA LEVELING AGENT zimasamukira pamwamba pa filimuyo chifukwa cha kusagwirizana pang'ono, zimakhudza mawonekedwe a filimuyo monga INTERfacial tension, ndipo zimapangitsa kuti filimuyi ikhale yabwino.
ntchito
Ntchito yaikulu ya zokutira ndi zokongoletsera ndi chitetezo, ngati pali zofooka zoyenda ndi zowonongeka, sizimangokhudza maonekedwe, komanso zimawononga ntchito yoteteza.Monga kupanga shrinkage chifukwa cha filimu makulidwe sikokwanira, mapangidwe a pinholes adzatsogolera filimu discontinuity, izi kuchepetsa filimu chitetezo.Popanga zomanga zomanga ndi kupanga mafilimu, padzakhala kusintha kwa thupi ndi mankhwala, kusintha kumeneku ndi chikhalidwe cha chophimba chokhacho, chidzakhudza kwambiri kutuluka ndi kusanja kwa zokutira.
Pambuyo pakuyikapo, mawonekedwe atsopano adzawonekera, nthawi zambiri mawonekedwe amadzimadzi / olimba pakati pa zokutira ndi gawo lapansi ndi mawonekedwe amadzimadzi / gasi pakati pa zokutira ndi mpweya.Ngati kugwedezeka kwapakati pa mawonekedwe amadzimadzi / olimba pakati pa zokutira ndi gawo lapansi ndipamwamba kuposa kugwedezeka kwakukulu kwa gawo lapansi, chophimbacho sichidzatha kufalikira pa gawo lapansi, zomwe mwachibadwa zidzatulutsa zolakwika monga fisheye ndi kuchepa. mabowo.
The Evaporation OF SOLVENT PAKATI PA KUYAMUKA kwa filimuyi kudzachititsa kuti kutentha, kachulukidwe ndi kusamvana kwapakati pakhale kusiyana pakati pa pamwamba ndi mkati mwa filimuyo.Kusiyana kumeneku kumapangitsa kuti pakhale chisokonezo mkati mwa filimuyi, ndikupanga otchedwa Benard vortex.Benard vortex imatsogolera ku peel lalanje;Mu machitidwe omwe ali ndi pigment yoposa imodzi, ngati pali kusiyana kwina kwa kayendedwe ka pigment particles, Benard vortex ingathenso kutsogolera ku mtundu woyandama ndi tsitsi, ndipo kumanga koyimirira kudzatsogolera ku mizere ya silika.
KUYAMUKA KWA FILM YA PAINT NTHAWI ZINA ZIMENE ZINA ZINTHU ZOSAVUTA ZA COLLOIDAL, KUKHALA KWA particles insoluble COLLOIDAL kumapangitsa kuti pakhale phokoso lapamwamba, lomwe nthawi zambiri limatsogolera kupanga mabowo a shrinkage mufilimu ya utoto.CHITSANZO, MU CROSS-LINKED CONSOLIDATION SYSTEM, KUMENE KUKHALA KUKHALA NDI RESIN imodzi, utomoni wosasungunuka ukhoza kupanga tinthu tating'onoting'ono ta colloidal pamene zosungunulira zimasungunuka panthawi yowumitsa filimu ya utoto.Komanso, mu chiphunzitso munali surfactant, ngati surfactant si yogwirizana ndi dongosolo, kapena mu kuyanika ndondomeko ndi volatilization wa zosungunulira, ndende yake kusintha kumabweretsa kusintha solubility, mapangidwe zosagwirizana m'malovu, komanso kupanga pamwamba. kukangana.Izi zingapangitse kupanga mabowo ocheperako.
Pakupanga zokutira ndi kupanga filimu, ngati pali zoipitsa zakunja, zingayambitsenso dzenje la shrinkage, fisheye ndi zolakwika zina.Zoipitsa izi nthawi zambiri zimachokera ku mpweya, zida zomangira ndi mafuta apansi panthaka, fumbi, chifunga cha utoto, nthunzi yamadzi, ndi zina zambiri.
Zida za utoto wokha, monga viscosity yomanga, nthawi yowumitsa, ndi zina zotero, zidzakhudzanso kwambiri kukwera komaliza kwa filimu ya utoto.Kuchulukira mamachulukidwe okwera kwambiri komanso nthawi yayifupi yowumitsa nthawi zambiri kumapangitsa kuti pakhale kusanja bwino.
Choncho, m'pofunika kuwonjezera kusalaza wothandizila, mwa ❖ kuyanika mu ndondomeko yomanga ndi filimu mapangidwe kusintha ndi ❖ kuyanika katundu kusintha, kuthandiza utoto kupeza mlingo wabwino.
phukusi ndi transport
B. Izi mankhwala angagwiritsidwe ntchito, 25KG, 200KG, 1000KG migolo.
C. Sungani chosindikizidwa mu malo ozizira, owuma ndi mpweya wokwanira m'nyumba.Zotengera ziyenera kutsekedwa mwamphamvu mukatha kugwiritsa ntchito chilichonse musanagwiritse ntchito.
D. Mankhwalawa ayenera kusindikizidwa bwino panthawi yoyendetsa kuti ateteze chinyezi, alkali wamphamvu ndi asidi, mvula ndi zonyansa zina kuti zisasakanike.
