Gulu la Colorcom linapanga mtundu watsopano wa zokutira: zokutira zochokera ku silika, zomwe zimapangidwa ndi silikoni ndi acrylic copolymer. Chophimba chopangidwa ndi silicon ndi mtundu watsopano wa zojambulajambula zokhala ndi mawonekedwe enaake pogwiritsa ntchito emulsion yolimbitsa silikoni monga chinthu chachikulu chopangira filimu komanso silika yoyera kwambiri ngati pigment yapakati pathupi.
1. Mapangidwe
Silicone emulsion, silicon dioxide,
Emulsion ya silicone:
Acrylic acid monga apamwamba zopangira ❖ kuyanika kupanga, ali osiyanasiyana zochitika ntchito, silikoni analimbitsa emulsion zachokera akiliriki emulsion, ntchito silikoni kusinthidwa ngati mkulu mphamvu emulsion, ndi chiwembu kusintha mabuku ntchito. za zokutira.
Silicon dioxide:
Silicon dioxide ndi mtundu wapamwamba kwambiri wa pigment, wokhala ndi kukana kolimba, kuuma kwakukulu, mawonekedwe amphamvu a nyengo, koma chiŵerengero cha silika ndi chachikulu, chosavuta kugwa, kotero kuchuluka kwake kowonjezera mu dongosolo lopangira zokutira sikuchulukira. Kuchuluka kwa silika wowonjezeredwa mu zokutira zochokera ku silicon kwawonjezeka kwambiri, ndipo silika yake ikhoza kukhala nthawi 5 mpaka 10 kuposa zokutira wamba.
2. Mfundo zaukadaulo
Tekinoloje yolimbikitsa ya silicone
Ma polymerization reaction of acrylic resin amapanga emulsion ya utoto wapamwamba kwambiri. Utoto wa acrylic umakhala ndi chitetezo chokwanira kwambiri, koma uli ndi zofooka monga kusakanizidwa ndi madzi, kusamata bwino, kutentha kwambiri, komanso kuuma pang'ono. Pofuna kuthana ndi zofooka za acrylate, kafukufuku wasonyeza kuti pochotsa carbon element mu C = O double bond mu acrylate ndi silicon element, emulsion yolimbitsa silikoni ingapezeke. Popeza mphamvu ya mgwirizano wa Si = O mgwirizano wapawiri ndi wapamwamba, emulsion imakhala yokhazikika, ndipo kukana kwake kwa nyengo, kukana madzi, ndi kumamatira kumatha kusintha kwambiri.
3. Ubwino
Mapangidwe apakati
Zovala zokhala ndi silicon nthawi zambiri zimakhala ndi mawonekedwe apakatikati, mawonekedwe owoneka ndi manja ndizosiyana ndi utoto wamba wa latex, womwe umatchedwa mtundu wa utoto waluso, chifukwa utoto wa utoto wopangidwa ndi silicon uli ndi tinthu tambiri tambiri tomwe timatulutsa mchere wa pigment, kotero silicon. -zopaka utoto nthawi zambiri zimakhala ndi zitsulo zina.
Kukoma koyera ndi kuteteza chilengedwe
Popeza zokutira za silicone zimagwiritsa ntchito ma emulsions osinthidwa ndi kulimbikitsa silikoni monga chinthu chachikulu chopangira filimu, zowonjezera zochepa kwambiri zimagwiritsidwa ntchito popanga zopaka pambuyo pake, motero zimakhala ndi chitetezo chambiri choteteza chilengedwe ndipo ndi chimodzi mwazovala zaposachedwa kwambiri. mitundu. Utoto weniweni wopangidwa ndi silikoni ukhoza kusunthidwa mkati mwa maola 4 mutapenta, ndipo kwenikweni sutulutsa zinthu zovulaza mumlengalenga.
Kuuma kwakukulu
Chophimba chopangidwa ndi silicon chimagwiritsa ntchito silika ngati pigment pachimake, kotero kuuma kwathunthu kwa filimu yophimba ndipamwamba, kukana kuvala kuli bwino, moyo wautumiki wa filimu yophimba ndi yaitali;
4. Njira zomangira
Chophimba chopangidwa ndi silicon ndi choyenera popangira kupopera mbewu mankhwalawa, chifukwa zokutira zokhala ndi silicon zimakhala ndi mawonekedwe ena a granular, kuti zitsimikizire kutulutsa kosalala, ndikofunikira kugwiritsa ntchito mfuti yopopera yopangidwira njira zakuthupi ndi kulekanitsa njira ya gasi.
5. Kuchuluka kwa ntchito
Utoto wopangidwa ndi silicone ndi utoto waluso wokhala ndi mawonekedwe ang'onoang'ono, omwe ndi oyenera kukongoletsa khoma lamkati lamkati ndi chitetezo chachilengedwe komanso zofunikira zapamwamba. Ndikoyenera makamaka kukongoletsa khoma lapamwamba kwambiri.
6. Zoyembekeza zamakampani
Ukadaulo wolimbitsa thupi wa silicone ndi gawo lofunikira lofufuzira laukadaulo wosinthira zokutira. Pakalipano, zochitika zogwiritsira ntchito zikukula kwambiri. Zovala zokhala ndi silicon zimakhala ndi mawonekedwe oteteza chilengedwe, kukoma koyera, moyo wautali wautumiki, filimu yopaka utoto wandiweyani, kukana dothi komanso kukana kuvala kwakukulu, komwe kuli koyenera kwamitundu yonse yanyumba. Kudzera pakufufuza kosalekeza kwaukadaulo ndi chitukuko ndi luso, zokutira zokhala ndi silicon zidzakhala chimodzi mwazinthu zomwe zitukuko pamsika wamtsogolo.
