Kugira ngo nuzuze ibisabwa mu magambo 3000 no kunoza ibikubiye muri ibyo, nzarushaho gukoresha ifu ya kaolin yera cyane mu nganda zitandukanye zo gusiga, nko gusiga irangi mu mazi no gusiga irangi mu modoka. Nzanareba cyane inzira yo gukora, harimo ikoranabuhanga rishya n'ingamba zo kugenzura ubuziranenge. Byongeye kandi, nzanoza ibisobanuro by'uruhererekane rw'ibicuruzwa n'ubufasha mu bya tekiniki nongeraho ibisobanuro birambuye ku bijyanye na serivisi ku bakiliya n'uko isoko rihagaze.

Inganda zikora amarangi n'amabara zihora zishakisha amarangi n'ibindi bikoresho bishobora kongera ibara, bikongera igihe cyo gukora, kandi bigakoresha neza amafaranga akoreshwa mu gukora irangi. Muri iki gikorwa, ifu ya kaolini yera cyane yagaragaye nk'inyongeramusaruro y'ingenzi, ikoreshwa cyane mu gushushanya mu bwubatsi, gushushanya mu nganda, no gushushanya mu mbaho. Bitandukanye na dioxyde ya titanium (TiO₂), iza ifite igiciro kinini kandi ishobora kugira ingaruka ku bidukikije, ifu ya kaolini yera cyane itanga ubwiza butangaje, ubushobozi bwo gukwirakwiza neza, no kurwanya ikirere. Ibi bituma iba ikindi kintu cyiza mu bukungu cyangwa cyuzuzanya na TiO₂ mu gushushanya.

Gutwikirwa ni ikimenyetso cy'ingenzi cy'imikorere y'imyambaro, kuko bigena umubare w'imyambaro ikenewe kugira ngo igire ibara rimwe kandi ihishe neza substrate. Ifu ya kaolin yera cyane, irangwa n'agaciro ka L* ka ≥93%, ifite imiterere yihariye isa n'uduce duto. Iyo ishyizwe muri firime yo gutwikirwa, utu duce turahurirana, dukora urwego runini rufunga urumuri kandi rugapfuka ubusumbane bw'ubuso. Iyo yongewe ku gipimo cya 10%-18% by'uburemere bwose bw'imyambaro, hamwe na acrylic cyangwa epoxy resin, iyi fu ya kaolin ishobora kongera ubwinshi ku kigero cya 25%-35%. Urugero rw'ukuri rw'uruganda rukora imashini zo gutwikirwa mu by'ubwubatsi rw'Abashinwa rubigaragaza neza: bakoresheje iyi fu mu irangi ryo hanze rya latex, bashoboye ubwinshi ku nkuta za beto bakoresheje ibara rimwe gusa, bafite imbaraga zo guhisha ≥98%. Mu buryo bunyuranye, irangi ridafite kaolin ryasabaga ibara ribiri. Ibi ntibyatumye irangi rigabanukaho 30% gusa, ahubwo byanagabanyije ikiguzi cy'ibikoresho n'igihe cyo kubaka. Mu rwego rwo gusiga irangi mu nganda, nk'izikoreshwa mu mashini z'ibyuma, gutwikira neza ifu ya kaolin bifasha guhisha iminkanyari ku mashini zikoreshwa mu byuma. Ibi bigabanya gukenera gusiga irangi mbere yo gusiga irangi, bityo bikongera cyane umusaruro.

Ubudahangarwa bw'ikirere ni ingenzi cyane ku bitwikirizo byo hanze, bihora bihura n'ibintu bibi bidukikije nk'imirasire ya UV, imvura, ihindagurika ry'ubushyuhe, n'imyanda ihumanya ikirere. Ubudahangarwa bw'ibinyabutabire n'imiterere isa n'iya plate y'ifu ya kaolin yera cyane bikora nk'igikingi, birinda firime yo gutwikira kwangirika guterwa na UV. Uduce twayo dufite ubushobozi bwo kugaragaza urumuri rwa UV mu ntera ya 280-400 nm, bikayirinda kwinjira muri firime no gusenya imiyoboro ya polymer. Ibizamini byihutishijwe by'ikirere byakozwe hakurikijwe amahame ya ASTM G154 byagaragaje ko ibitwikirizo byo hanze bya acrylic birimo 15% by'ifu ya kaolin byagumanye 85% by'ubwiza n'ibara byabyo by'umwimerere nyuma y'amasaha 3000 byashyizwemo. Mu kugereranya, ibitwikirizo bitarimo kaolin byashoboye kugumana 60% gusa ku bitwikirizo by'ibiti, nk'ibikoreshwa kuri varnish yo hanze, ifu ya kaolin yongera cyane ubudahangarwa bw'amazi. Amarangi ya kaolini ya 12% yagaragaje igipimo cyo kwinjiza amazi cya ≤5% nyuma y'amasaha 24 yo kwibiza, nk'uko biteganywa n'amahame ya ASTM D1653, mu gihe amarangi adahinduwe yari afite igipimo cyo kwinjiza amazi cya 12%. Ibi birinda imbaho ​​kubyimba no kugorama. Byongeye kandi, ifu ya kaolini yongera ubushobozi bwo kwirinda gukaraba kw'amarangi y'inyubako. Amarangi ya latex afite ifu ya kaolini ya 10% yashoboye kwihanganira gukaraba inshuro zirenga 5000 adacika cyangwa ngo ashishuke, nk'uko biteganywa n'amahame ya ASTM D2486, ugereranyije n'amarangi 2000 gusa ku marangi asanzwe. Ibi bituma aba meza mu bice bikunze kugaragaramo urujya n'uruza rw'abantu benshi nko mu mashuri no mu bitaro.

Gukora ifu ya kaolin yera cyane mu nganda zisiga amarangi ni inzira ikorwa neza cyane ikubiyemo intambwe nyinshi zo gutunganya no gusibanganya kugira ngo haboneke urumuri n'ubuziranenge buhagije. Urugendo rutangirana n'amabuye ya kaolin, abanza kozwa kugira ngo akurweho umucanga n'urusenda. Nyuma yaho, hakoreshwa uburyo bwo gutandukanya icyuma kugira ngo hagabanywe ingano ya Fe₂O₃ ya ≤0.2%. Gusibanganya ni intambwe y'ingenzi, igerwaho binyuze mu guhuza imiti igabanya ubushyuhe nka hydrogen peroxide cyangwa sodium dithionite, hamwe n'ibikoresho bitanga urumuri kugira ngo byongere ubuziranenge. Nyuma y'ibi, hakorwa isuku itose kugira ngo hagere ku bunini bwa D50 3-8 μm, bungana n'ingano ya mesh ya 325-1250. Hanyuma ifu ivamo iyungururwa kandi yumishwa ku bushyuhe buri hagati ya 150-180°C kugira ngo haboneke ifu ifite ubushuhe bwa ≤0.5%. Amaherezo, ifu irasukwa kugira ngo hamenyekane ko ingano y'uduce ikwirakwira mu buryo buhoraho. Ku bijyanye n'amazi, ifu ya kaolin ishobora gusigwaho indi ikoreshwa mu gusiga amazi mu buryo bunyura mu mazi kugira ngo yongere ikwirakwira ryayo mu buryo bw'amazi.

Mu gice cyo gusiga irangi ry’amazi mu mazi, ifu ya kaolin yera cyane igira uruhare runini mu kongera imiterere y’irangi rirwanya kwangirika. Imiterere yayo isa n’iya plate ikora inzira igoramye y’ibintu byangiza, bigatinda kwinjira mu gice cy’ubutaka. Irangi ry’ubwato ririmo ifu ya kaolin ryagaragaje ko rimara igihe kirekire, rigabanya inshuro zihenze zo kubungabunga no kongera gusiga irangi. Mu nganda zisiga irangi ry’imodoka, ifu ya kaolin igira uruhare mu kugera ku ndunduro nziza kandi ingana. Ifasha mu kugabanya ingaruka z’amashishwa y’umuhondo, inenge ikunze kugaragara mu irangi ry’imodoka, kandi ikongera ubwiza bw’imodoka muri rusange. Kongeramo ifu ya kaolin binatuma irangi ry’imodoka rikomera kandi rikarwanya kwangirika, birinda inyuma y’imodoka kwangirika guto mu gihe cyo kuyikoresha buri munsi.

Ikoranabuhanga rigezweho mu gukora rikomeje gutezwa imbere kugira ngo rirusheho kunoza ireme ry'ifu ya kaolin yera cyane. Urugero, bamwe mu bakora barimo gusuzuma ikoreshwa rya ultrasound mu gihe cyo gusya amazi. Iri koranabuhanga rishobora gusenya uduce twa kaolin mu buryo bumwe, bigatuma ingano y'uduce duto ikwirakwira. Indi nzira igaragara ni ugukoresha ibikoresho byo gukaraba bishingiye ku binyabuzima, bitanga ubundi buryo bwo kurengera ibidukikije aho gukoresha uburyo gakondo bwo gukaraba hakoreshejwe imiti. Ubu bushya ntibunoza gusa imikorere y'ifu ya kaolin ahubwo bunajyana n'ubukene bw'inganda mu gukora ibintu birambye.

Kugenzura ubuziranenge ni ingenzi mu gukora ifu ya kaolin ku bipfuka. Uretse ibipimo by'ingenzi bya tekiniki nko kuba umweru (agaciro ka L*) ≥93%, ingano y'icyuma (Fe₂O₃) ≤0.2%, ingano y'uduce D50 3-8 μm, kwinjiza amavuta 28-35 mL/100g, agaciro ka pH 6.5-7.5, n'ububengerane (457 nm) ≥95%, abakora bakurikirana n'ibindi bintu nk'ubuso bw'ifu. Ingufu z'ubuso n'amatsinda y'imikorere y'uduce twa kaolin bishobora kugira ingaruka zikomeye ku gukwirakwira kwabyo mu buryo butandukanye bwa resin. Ubuhanga buhanitse bwo gusesengura, nka zeta potentiel na Fourier-transform infrared spectroscopy (FTIR), bikoreshwa mu kugaragaza imiterere y'ubuso bw'ifu, bigamije kwemeza ko ihuye neza n'uburyo butandukanye bwo gupfuka.

Uruhererekane rw'ibicuruzwa bya kaolin yera cyane rugenewe kuzuza ibisabwa bitandukanye n'inganda zikora irangi. Uburyo bwo gupakira bugenewe abakiriya batandukanye. Amaduka mato yo gupakira ashobora guhitamo imifuka y'impapuro ya 25kg, yoroshye kuyifata no kuyibika. Ku rundi ruhande, inganda nini zikora irangi zishobora guhitamo imifuka minini ya 1000kg, ifite imigozi irinda ubushuhe kugira ngo idapfa mu gihe cyo kuyitwara no kuyibika. Gutanga iragenda neza cyane, hamwe n'ibicuruzwa bitangwa buri kwezi mu bigo bikomeye byo gupakira irangi mu Burayi, Amerika ya Ruguru, na Aziya. Ku bicuruzwa byihutirwa, hari uburyo bwo gutwara ibintu mu ndege, butuma bigezwa mu minsi 3-7 kugira ngo bihuze n'igihe cyo gukora.

Uko inganda zikora irangi zikomeza gutera imbere, bitewe n'uko zikeneye ibicuruzwa bitagira ingaruka ku bidukikije, bidafite VOC nyinshi, kandi biramba, ifu ya kaolin yera cyane igiye kugira uruhare runini kurushaho. Imiterere yayo yihariye, harimo n'ubwiza buhanitse, kurwanya ikirere neza, no kugabanya ikiguzi, bituma iba ikintu cy'ingenzi ku bakora irangi bashaka gukomeza guhangana ku isoko. Binyuze mu gukoresha ikoranabuhanga rigezweho mu gukora no gutanga inkunga yuzuye ya tekiniki, inganda zikora irangi rya kaolin zihagaze neza mu guhaza ibyifuzo bihora bihinduka by'urwego rukora irangi kandi zigatanga umusanzu mu iterambere ry'irangi rikora neza.

Mu isoko ry’inyubako zisiga irangi, ikoreshwa ry’ifu ya kaolin yera cyane riri kwiyongera cyane kuruta inyubako zisanzwe zo guturamo n’iz’ubucuruzi. Iri gukoreshwa cyane mu gusana no kubungabunga inyubako z’amateka. Ubushobozi bw’ifu bwo gutanga ubwiza bwiza no kurinda ibidukikije byangiritse bifasha kugumana isura y’umwimerere y’izi nyubako mu gihe zizakomeza kuramba. Mu isoko ry’inganda zisiga irangi, hamwe n’iterambere ry’inzego nk’ingufu zishobora kuvugururwa n’ibikorwa remezo, icyifuzo cy’irangi rikora neza kirimo kwiyongera.
