Kuva ku miterere mishya y’ubwubatsi kugeza ku bikorwa by’umwuga, ikirahure cyabaye ibikoresho bifite akamaro kanini kandi bigira uruhare runini mu bihe byinshi bidasanzwe. Ikintu cy’ingenzi mu kubungabunga ikirahure ni uburyo bwiza bwo kugisukura. Byaba ari ubuhanzi bworoshye cyangwa ubuso bw’ikirahure bukora neza, kumenya gusiga ikirahure bishobora kugira ingaruka zikomeye ku bwiza bwacyo no ku gihe cyacyo. Gusiga irahure ntibyongera gusa ubwiza ahubwo binakuraho ibisebe, iminkanyari, n’ibisebe bishobora kubangamira ubwiza bwacyo. Niba ushaka kumenya uburyo bwo gusiga irahure, soma iyi nkuru.
Uburyo bwo gusiga ikirahure?
1. Gusukura no gutegura ubuso bw'ibirahuri mbere yo gusiga irahuri
Intambwe ya mbere ni ugupfunyika kaseti ku nkengero z'ikirahure kigiye gutogoshwa. Ubu buryo bwo kwirinda burinda imyanda cyangwa imvange yo gutogoshwa gukwirakwira ku buso bwegereye mu gihe cyo gutogoshwa. Mu gukora uruzitiro rurinda, ushobora kwibanda ku kugarura imiterere y'ikirahure mbere nta kwangirika kwabyo ahandi.
Intambwe ya kabiri ishimangira akamaro ko gusukura neza. Mbere yo gusiga irangi, ivumbi, umucanga, cyangwa indi myanda ishobora kuba iri ku buso bw'ikirahure igomba gukurwaho. Imyanda iyo ari yo yose ishobora gukurwaho witonze hakoreshejwe igitambaro kidafite irangi cyangwa imashini yihariye yo gusukura ikirahure. Ibi bituma irangi risukuye kandi rigenda neza, bigatuma inzira yo gusiga irangi irushaho kuba nziza.
Noneho, reka twige mu buryo burambuye ku bijyanye no gushyira ikimenyetso ku gace kagomba gusigwa. Koresha ikimenyetso kugira ngo ukurikirane witonze ibice biri inyuma y'ikirahure bikenewe kwitabwaho. Iri koranabuhanga riyobora inzira yo gusigwa, rikarinda kugenda ku buryo butunguranye no kwaguka mu buryo butunguranye k'agace kasigwa. Ukoresheje uburyo nyabwo bwo kugaragaza ahantu hateye impungenge, ushobora gukemura buri gace neza, ukareba uburyo bwo gusigwa neza kandi bugenzurwa.
2. Koresha ikirahure cya 120#, 240#, 400#, 600#urupapuro rwo gusendakoza imikoba y'ibirahuri
Ni byiza gusuka igice gito cy'amazi yo gusiga uko bikenewe hanyuma ukayasukamo amazi mu gipimo cya 1:1 cyangwa nturenze 1:5. Uyu muti wo gusiga wakozwe by'umwihariko kugira ngo usigashe mu mucanga kugira ngo ubone umusaruro mwiza kandi wirinde kwangirika k'ubuso bw'ikirahure. Mu gihe usiga irangi, menya neza ko witonze akamaro k'amazi yo gusiga ahagije. Nta na rimwe impapuro zo gusiga zigomba gukoreshwa mu gusiga ku buso bw'ikirahure byumye. Kuba hari amazi yo gusiga ahagije ntabwo byongera gusa imikorere y'umucanga ahubwo binarinda kwangirika kw'ikirahure mu gihe cyo gutunganya.
Noneho, reka turebe intambwe ku yindi mu gukuraho ubwoko butandukanye bw'imikoba y'ibirahuri. Ku mikoba miremire kandi igaragara ishobora kumvikana byoroshye n'amaboko yawe, ni byiza gukoresha uburyo bw'intambwe eshatu. Ubwa mbere, koresha sandpaper y'ibirahuri ya 120# mu gusya mbere. Iyi sandpaper ikomeye ifasha gutunganya impande z'imikoba, igatanga inzira yo gusana neza. Nyuma yo gusya bwa mbere, komeza ku ntambwe ikurikira, ari yo gukoresha sandpaper ya 240#. Iyi sandpaper nziza irushaho kunoza ubuso, ikabuha ishusho nziza. Amaherezo, koresha sandpaper ya 600# mu gusya bwa nyuma kugira ngo ugere ku bisabwa byo gusya neza. Ariko, ni ngombwa kumenya ko niba ubuso busa neza nyuma yo gusya no gusya bwa mbere, ushobora gusimbuka intambwe ya nyuma yo gusya hanyuma ugakomeza ku ntambwe ikurikira. Kugira ngo ubone imikoba mito (ishobora kutamenyekana vuba n'intoki, ariko izagaragara neza n'ibimenyetso by'umweru), ni byiza gukoresha inzira yoroshye. Ubwa mbere, koresha sandpaper y'ibirahuri ya 400# mu gusya bwa mbere. Iyi grit yo hagati ifasha kugabanya isura y'imishishwa kandi igategura ikirahure kugira ngo gikomeze kurangizwa. Hanyuma, koresha sandpaper ya 600# kugira ngo utunganye ubuso kugira ngo ugere ku bisabwa byo gukosora. Mu buryo nk'ubwo, niba ibisubizo nyuma yo gusya bwa mbere bishimishije, ushobora guhitamo gusimbuka intambwe ya nyuma yo gukosora hanyuma ugahita ujya mu byiciro bikurikira.
3. Simbuza amazi yo gusiga hanyuma ukoreshe uruziga rwihariye rwo gusiga kugira ngo usubize ikirahure ku mucyo.
Tangira usukura neza ubuso bw'ikirahure kugira ngo urebe neza ko nta mwanda cyangwa imyanda irimo. Reba ingano y'udupira tw'impapuro zikenewe mu gusiga irangi. Siga irangi rikwiye ku buso bw'ikirahure. Menya neza ko isahani yo gusiga irambitse ku buso bw'ikirahure kugira ngo urebe ko irangi ringana. Niba udafite imashini yo gusiga irangi, ushobora gukoresha disiki yo gusiga irangi n'intoki. Jya buhoro buhoro kandi witonze mu gihe cyo gusiga irangi kandi wirinde kugenda vuba cyane. Koresha uruziga cyangwa pad yihariye yo gusiga irangi kugira ngo usukemo igitutu gikwiye kugira ngo ugere ku ngaruka wifuza. Gira umwete kandi wihangane kandi urebe neza ko upfutse agace kose karimo. Niba urumuri cyangwa ubuziranenge bidashimishije nyuma yo gusiga irangi ku nshuro ya mbere, subiramo intambwe zavuzwe haruguru kugeza igihe ubonye umusaruro wifuza.
Icyitonderwa: Ni ngombwa kwibuka ko gusiga irangi bishobora kugira ingaruka ku mutekano w'ikirahure, cyane cyane iyo ubujyakuzimu bw'ikirahure burenze mikoroni 100. Ku birahuri by'imodoka, gusiga irangi rifite ubujyakuzimu burenze mikoroni 100 ntibigomba gusiga irangi. Muri make, inzira ikubiyemo gusiga irangi ritose ukoresheje sandpaper kugira ngo ukureho buhoro buhoro imikoba, hanyuma ugakoresha ipine cyangwa agapapuro ko gusukura gafite amazi yo gusukura kugira ngo ubone urumuri kandi wongere ugarure urumuri rw'ikirahure.
Uburyo bwo gusya impande z'ibirahuri neza kandi zigatanga urumuri?
Ubwa mbere, hitamo uruziga rwa diyama rukoreshwa mu byuma. Kugira ngo ukoreshe uru ruziga, banza ukoreshe umucanga ukomeye kugira ngo ukureho ubukana ku nkengero. Buhoro buhoro koresha utubuto two hagati n'utworoshye kugira ngo woroshye ubuso. Gukata impande ni ibisanzwe muri iki gikorwa. Ntugatinye, ibi bishobora gukosorwa mu ntambwe ikurikira. Nyuma yo gukata impande, hindura ukoreshe uruziga rwa diyama rufatanye na resin. Uru ruziga ruzagufasha gukora ubuso bwo gukata nta kundi gukata. Fata umwanya wawe urebe neza ko impande zoroshye kandi nta busembwa. Iyi ntambwe ni ingenzi kuko itegura impande zo ku rwego rwa nyuma rwo gukata.
Niba ushaka irangi rimeze nk'indorerwamo ku nkengero z'ikirahure cyawe, ni cyo gihe cyo gutera intambwe ya nyuma - ukoresheje ipine rihanagura. Aho guhitamo irangi rikozwe muri diyama, hitamo irangi rihanagura rito cyane nka oxide y'icyuma na oxide ya cerium. Ibi bikoresho sukura buhoro buhoro impande kugira ngo ubone ubuso bwiza. Kurikiza witonze amabwiriza y'uwakoze ku bwoko n'ingano ya polishing abrasive yo gukoresha. Mu ntambwe ya kabiri yo gusya, niba ukoresha icyuma gisya amazi cya 3000-grit, uzasanga impande z'ikirahure zihinduka nk'izibonerana. Ibi bigaragaza ko uri mu nzira yo kugera ku mucyo n'ubuhanga wifuza. Wibuke ko kwihangana no kwita ku tuntu duto ari ingenzi mu gihe ukoresha impande z'ikirahure. Fata umwanya wawe kandi ntuhutire. Buri ntambwe igira uruhare runini mu kugera ku musaruro mwiza. Noneho ko ufite ubumenyi, ushobora gukomeza gukora imishinga myiza y'ikirahure ifite impande nziza kandi zisekuye.
