Hydroxyethyl Cellulose Ether

Hydroxyethyl cellulose ether, non-ayoni pamwamba yogwira ntchito, ndi kaŵirikaŵiri pa cellulose ether organic madzi-based inki thickener. Ndi madzi osungunuka omwe si a ionic ndipo amatha kukhuthala bwino madzi.

Lili ndi makhalidwe ambiri monga thickening, kuyandama, kugwirizana, emulsifying, filimu-kupanga, kuika maganizo, kuteteza madzi kuti asatuluke nthunzi, kupeza ndi kuonetsetsa ntchito ya particles, komanso ali ndi katundu ambiri apadera.

Wobalalitsa

Dispersant ndi surfactant yomwe ili ndi zinthu ziwiri zosiyana za lipophilicity ndi hydrophilicity mu molekyulu. Iwo akhoza uniformly kumwazikana olimba ndi madzi particles wa inorganic ndi organic inki kuti n'zovuta kupasuka mu madzi, ndipo pa nthawi yomweyo kuteteza particles kukhazikika ndi agglomerating, kupanga ndi amphiphilic wothandizira chofunika khola kuyimitsidwa.

Ndi dispersant, amatha kusintha gloss, kuteteza mtundu woyandama, ndi kupititsa patsogolo tinting mphamvu. Zindikirani kuti tinting mphamvu si mkulu monga momwe angathere mu mtundu mtundu dongosolo, kuchepetsa mamasukidwe akayendedwe, kuonjezera Mumakonda inki, etc.

Wonyowetsa wothandizira

Wothira wothira amatenga gawo lalikulu mu dongosolo lopaka utoto, lomwe limatha kufika pamwamba pa gawo lapansi loyamba "kukonza msewu", ndiyeno chinthu chopanga filimu chikhoza kufalikira mu "msewu" womwe wothirira wayenda. M'madzi opangira madzi, wothira madzi ndi wofunika kwambiri, chifukwa kuthamanga kwa madzi kumakhala kwakukulu kwambiri, kufika pa 72 dynes, yomwe imakhala yochuluka kwambiri kuposa kugwedezeka kwapansi kwa gawo lapansi. Kufalikira otaya.

Antifoaming wothandizira

Defoamer imatchedwanso defoamer, antifoaming agent, ndi thovu amatanthauza kuchotsa thovu. Ndi chinthu chomwe chimakhala ndi kutsika kwapansi komanso ntchito yapamwamba, yomwe imatha kupondereza kapena kuthetsa thovu mu dongosolo. Zithovu zambiri zovulaza zidzapangidwa popanga mafakitale, zomwe zimalepheretsa kwambiri kupita patsogolo kwa kupanga. Panthawi imeneyi, m'pofunika kuwonjezera defoamer kuchotsa thovu zoipa izi.

Titaniyamu dioxide

Makampani opanga utoto ndi omwe amagwiritsa ntchito kwambiri titanium dioxide, makamaka rutile titanium dioxide, ambiri mwa iwo omwe amagwiritsidwa ntchito ndi mafakitale opaka utoto. Utoto wopangidwa ndi titaniyamu woipa uli ndi mitundu yowala, mphamvu zobisalira zambiri, mphamvu yopangira tinting, mlingo wochepa, ndi mitundu yambiri. Ikhoza kuteteza kukhazikika kwa sing'anga, ndipo imatha kupititsa patsogolo mphamvu zamakina ndi kumamatira kwa filimu ya utoto kuteteza ming'alu. Zimalepheretsa kuwala kwa UV ndi chinyezi kuti zisalowe, kumatalikitsa moyo wa filimu ya utoto.

Kaolin

Kaolin ndi mtundu wa zodzaza. Pogwiritsa ntchito zokutira, ntchito zake zazikulu ndi: kudzaza, kuonjezera makulidwe a filimu ya utoto, kupanga filimu ya utoto kukhala yochuluka komanso yolimba; kuonjezera kukana kuvala ndi kulimba; kusintha mawonekedwe a kuwala kwa chophimba, kusintha Maonekedwe a filimu yophimba; monga zodzaza mu zokutira, zimatha kuchepetsa kuchuluka kwa utomoni wogwiritsidwa ntchito ndikuchepetsa mtengo wopanga; imakhala ndi gawo lotsogola pamakina opangira filimu yokutira, monga kukulitsa anti- dzimbiri ndi retardancy lawi.

calcium yochuluka

Kashiamu wolemera akagwiritsidwa ntchito mu utoto womanga wamkati, amatha kugwiritsidwa ntchito payekha kapena kuphatikiza ndi ufa wa talcum. Poyerekeza ndi talc, kashiamu wolemera amatha kuchepetsa kuchuluka kwa chalking, kukonza kusungidwa kwa utoto wa utoto wopepuka ndikuwonjezera kukana nkhungu.

Mafuta odzola

Udindo wa emulsion ndi kuphimba pigment ndi filler pambuyo filimu mapangidwe (ufa ndi amphamvu mitundu mphamvu ndi pigment, ndi ufa wopanda utoto mphamvu ndi filler) kupewa ufa kuchotsa. Nthawi zambiri, ma emulsion a styrene-acrylic ndi pure acrylic amagwiritsidwa ntchito pamakoma akunja. Styrene-acrylic ndiyotsika mtengo, imasanduka yachikasu, acrylic yoyera imakhala ndi kukana kwanyengo komanso kusungirako utoto, ndipo mtengo wake ndi wokwera pang'ono. Utoto wakunja wapakhoma wocheperako nthawi zambiri umagwiritsa ntchito ma emulsion a styrene-acrylic, ndipo utoto wapakatikati mpaka kumapeto wapakhoma nthawi zambiri umagwiritsa ntchito ma emulsion oyera.

Fotokozerani mwachidule

Popanga zokutira, zida zothandizira zogwirira ntchito monga zoteteza ndi zowuma zimawonjezeredwanso.

Pamwambapa ndi kusanthula zikuchokera utoto zipangizo. Ndi chitukuko chosalekeza cha chuma, zofunika za anthu zokutira zimasinthanso nthawi zonse. Padzakhala zodabwitsa zambiri zomwe zikutiyembekezera pamsika wa utoto wamtsogolo!
