Uyu munsi tuzibanda kuburyo bwo kongeramo ubwoko bwihariye bwibibyibushye.
Ubwoko bwibisanzwe bikoreshwa cyane ni organorganic, selile, acrylic, na polyurethane.
Inorganic
Ibikoresho bidakoreshwa cyane cyane ni bentonite, silikoni yometse, nibindi, byongeweho mubisanzwe kugirango bisya, kuko bigoye kubirukana burundu kubera imbaraga zisanzwe zo kuvanga amarangi.
Hariho kandi agace gato kazatandukanywa kandi gategurwa muri gel kugirango ikoreshwe.
Birashobora kongerwaho amarangi mugusya kugirango ukore umubare runaka wa pre-gel. Hariho na bimwe byoroshye gutatanya kandi birashobora gukorwa muri gel ukoresheje umuvuduko mwinshi. Mugihe cyo kwitegura, gukoresha amazi ashyushye birashobora guteza imbere iki gikorwa.
Cellulose
Ibicuruzwa bikoreshwa cyane muri selile nihydroxyethyl selulose (HEC). Kugenda nabi no kuringaniza, kurwanya amazi adahagije, anti-mold nibindi bintu, ntibikunze gukoreshwa mumarangi yinganda.
Iyo ushyizwe mubikorwa, irashobora kongerwamo neza cyangwa gushonga mumazi mbere.
Mbere yo kongeramo, hagomba kwitonderwa guhindura pH ya sisitemu kumiterere ya alkaline, ifasha iterambere ryihuse.
Acrylic
Ibibyimba bya Acrylic bifite porogaramu zimwe murirangi. Ikoreshwa cyane cyane muburyo busanzwe busanzwe nkibigize kimwe hamwe nigipimo kinini cya pigment-shingiro, nkibikoresho byibyuma na primers ikingira.
Muri topcoat (cyane cyane ikoti isobanutse neza), ibice bibiri, guteka varnish, irangi ryinshi-ryinshi hamwe nubundi buryo, ifite inenge kandi ntishobora kuba ifite ubushobozi bwuzuye.
Ihame ryibyimbye rya acrylic niyongera ni: itsinda rya carboxyl kumurongo wa polymer ihindurwamo karubasi ya ionisiyonike mubihe bya alkaline, kandi ingaruka zo kubyimba zigerwaho binyuze mukwanga electrostatike.
Kubwibyo, pH ya sisitemu igomba guhinduka kuri alkaline mbere yo kuyikoresha, kandi pH nayo igomba kubikwa kuri> 7 mugihe cyo kubika nyuma.
Irashobora kongerwamo mu buryo butaziguye cyangwa ikavangwa n'amazi.
Irashobora gushonga mbere yo gukoreshwa kugirango ikoreshwe muri sisitemu zimwe zisaba guhagarara neza cyane. Mubisanzwe: banza ugabanye umubyimba wa acrylic ukoresheje amazi, hanyuma wongereho pH uhindura mugihe ukurura. Muri iki gihe, igisubizo kirabyimbye biragaragara, kuva amata yera kugeza kuri paste ibonerana, kandi irashobora gusigara ihagaze kugirango ikoreshwe nyuma.
Gukoresha ubu buryo bitanga imbaraga zo kubyimba, ariko birashobora kwagura byimazeyo mubyiciro byambere, ibyo bikaba bifasha guhagarara neza kwijimye nyuma yo gukora irangi.
Mugutegura no kubyaza umusaruro H1260 y'amazi ashingiye kumurongo umwe wifu ya silver yifu, umubyimba ukoreshwa murubu buryo.
Polyurethane
Ibibyimba bya polyurethane bikoreshwa cyane mubikorwa byinganda bifite imikorere myiza kandi birakwiriye gukoreshwa muri sisitemu zitandukanye.
Mubisabwa, ntakintu gisabwa kuri pH ya sisitemu, irashobora kongerwaho muburyo butaziguye cyangwa nyuma yo kuyungurura, haba mumazi cyangwa umusemburo. Ibibyimbye bimwe bifite hydrophilique nkeya kandi ntibishobora kuvangwa namazi, ariko birashobora kuvangwa gusa numuti.
Sisitemu
Sisitemu ya Emuliyoni (harimo na emulisiyo ya acrylic na hydroxypropyl emulsion) ntabwo irimo umusemburo kandi byoroshye kubyimba. Nibyiza kubyongera nyuma yo kuyungurura. Mugihe cyo kuyungurura, ukurikije kubyimbye neza kubyimbye, gabanya igipimo runaka.
Niba gukora neza ari bike, igipimo cyo kugabanuka kigomba kuba gito cyangwa ntigabanuke; niba kubyimbye neza ari byinshi, igipimo cya dilution kigomba kuba hejuru.
Kurugero, SV-1540 ishingiye kumazi ashingiye kuri polyurethane yibyimbye bifite umubyimba mwinshi. Iyo ikoreshejwe muri sisitemu ya emulsiyo, muri rusange ikoreshwa inshuro 10 cyangwa 20 (10% cyangwa 5%) kugirango ikoreshwe.
Hydroxypropyl Ikwirakwizwa
Hydroxypropyl dispersion resin ubwayo irimo urugero runaka rwumuti, kandi ntabwo byoroshye kubyimba mugihe cyo gukora amarangi. Kubwibyo, polyurethane muri rusange yongewemo mukigereranyo cyo kugabanuka cyangwa kongerwaho nta guhindagurika muri ubu bwoko bwa sisitemu.
Birakwiye ko tumenya ko bitewe ningaruka zumuti mwinshi, ingaruka zo kubyimba za polyurethane nyinshi zibyibushye muri ubu bwoko bwa sisitemu ntabwo zigaragara, kandi umubyimba ukwiye ugomba gutoranywa muburyo bugenewe. Hano, ndashaka gusaba SV-1140 ishingiye kumazi ashingiye kuri polyurethane ashyiramo umubyimba, ufite umubyimba mwinshi cyane kandi ufite imikorere myiza muri sisitemu yo gukemura cyane.
