Mitundu Yazowonjezera Zomangirira Zogwiritsidwa Ntchito Popaka Ufa Kapena Paint

Pali Mitundu Inayi Yowonjezera Zowonjezera Zogwiritsidwa Ntchito Mu Powder Coating Powder kapena Paint.

• Silika

M'munda wotakata wa silika wopezeka wokwera pali magulu awiri omwe amasiyana malinga ndi momwe amapangira. Imodzi ndi njira ya hydro-thermal, yomwe imapanga silika ndi morphology yofewa. Pogwiritsa ntchito njira ya silika-gel osakaniza amatha kupezeka omwe ali ndi morphology yovuta. Njira zonsezi zimatha kupanga silika wokhazikika komanso pambuyo popanga mankhwala. Pambuyo mankhwala zikutanthauza kuti silika pamwamba akhoza pang'ono kusinthidwa ndi organic (sera) kapena inorganic zipangizo. Poyerekeza ndi silika-gel osakaniza matting agents, silika kusinthidwa ali osiyana tinthu kukula, tinthu kukula kugawa, mu pore voliyumu. Ma hydrothermal matting agents ndi osiyana mu kukula kwa tinthu ndi kugawa. Titha kupezanso zida zosagwiritsidwa ntchito komanso zothandizidwa. Pakalipano pali chinthu chimodzi chokha chodziwika kuti chigwiritsidwe ntchito, chomwe chimapangidwa molingana ndi ndondomeko ya pyrogenic, ndipo chimasonyeza bwino kwambiri matting, makamaka m'makina amadzi.

Synthetic Aluminium silicates amagwiritsidwa ntchito mu utoto wa emulsion makamaka ngati chowonjezera chapamwamba kuti chilowe m'malo mwa Titandioxyd. Komabe, zitha kugwiritsidwanso ntchito popereka utoto wofananira wa emulsion wowuma. M'makina amafuta aatali a Alkyd amagwira ntchito ngati mating, koma ayenera kumwazikana ndi pigment ndi fillers. Silika zomangirira zimagwiritsidwa ntchito pazovala zonse, ngakhale osati zokutira zaufa.

• Mankhwala

Masiku ano, pali mitundu yosiyanasiyana ya sera pamsika. Sera zomwe zimagwiritsidwa ntchito kwambiri pakupaka ndi inki zimachokera ku Polyethylene, Polypropylene, Carnauba, Pakati. Mankhwala a waxes ozikidwa pa Polytetrafluorethylene PTFE amagwiritsidwanso ntchito ngati ma matting agents.

Mosiyana ndi silika, waxes amasintha mawonekedwe a filimu ya utoto poyandama pamwamba. Chodabwitsa ichi chimakhudza zotsatirazi katundu: mlingo wa matt / gloss; kutsika ndi kukana; anti blocking ndi abrasion properties, anti kukhazika mtima pansi ndi kugwedezeka kwa pamwamba.

Zambiri mwazinthuzo zimaperekedwa ngati mankhwala opangidwa ndi micronized, omwe amapezeka m'magulu osiyanasiyana omwe amapangidwa ndi sera emulsions. Ma dispersions amasiyana malinga ndi kukula kwa tinthu komanso kagawidwe kake.

• Zodzala

Ngakhale mawonekedwe a utoto amasintha kudzera pakuwonjezera zowonjezera zomwe zatchulidwa kale, magwiridwe antchito samakhudzidwa. Pogwiritsa ntchito zodzaza zenizeni timakulitsa bwino Pigment-Volume-Concentration ya utoto wokhudzana ndi zotsatira zake zonse. Ndicho chifukwa chake njira yokwerera ili ndi malire amtundu wa pigmented, otsika mtengo kachitidwe ka penti.

The fillers ndi amakonda yopapatiza tinthu kukula kugawa ayenera kumwazikana pamodzi ndi inki. Kuti musinthe digiri ya gloss yofunikira ndi praxis kuisintha pogwiritsa ntchito chipwirikiti mu Silika kumapeto kwa ntchito yopanga utoto.

• Zakuthupi

Ndi njira zamakono zopera ndizotheka kugaya zinthu zapulasitiki zozikidwa makamaka pa Poly methyl urea resin. Zogulitsa zoterezi zimakhala ndi mphamvu zochepa pa viscosity, zimasonyeza kutentha mpaka 200 ° C, zimakhala ndi zosungunulira zabwino, ndipo zimakhala zosavuta kumwazikana.

Zonsezi, Zowonjezera zonse zomwe zimagwiritsidwa ntchito popaka ufa kapena penti, zimakhala ndi ubwino ndi ubwino wake.
