Galasi limagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana chifukwa cha kusinthasintha kwake. Kupatulapo lomwe limagwiritsidwa ntchito kwambirizotengera zodzikongoletsera, imaphatikizapo mitundu yomwe imagwiritsidwa ntchito popanga zitseko ndi mawindo, monga magalasi opanda kanthu, magalasi opangidwa ndi laminated, ndi omwe amagwiritsidwa ntchito pokongoletsa zaluso, monga magalasi osakanikirana ndi magalasi ojambulidwa.
Makhalidwe a Kuphulika kwa Mchenga
Kuboola mchenga ndi njira yomwe mpweya wopanikizika umayendetsa zinthu zoboola pamwamba kuti zichiritsidwe. Imadziwikanso kuti kuboola kuwombera kapena kuboola kuwombera. Poyamba, mchenga unali wokhawo womwe unkagwiritsidwa ntchito, kotero njirayi nthawi zambiri imatchedwa kuboola mchenga. Kuboola mchenga kumakhala ndi zotsatira ziwiri: kumayeretsa pamwamba pa mlingo wofunikira ndikupanga kuuma pang'ono kuti kuwonjezere kumatirira kwa chophimba pa substrate. Ngakhale zophimba zabwino kwambiri zimavutika kumamatira bwino pamalo osakonzedwa kwa nthawi yayitali.
Kukonza pamwamba pa nthaka kumaphatikizapo kuyeretsa ndikupanga kuuma kofunikira kuti "kutseke" chophimbacho. Zophimba za mafakitale zomwe zimagwiritsidwa ntchito pamalo okonzedwa ndi mchenga zimatha kukulitsa moyo wa chophimbacho ndi nthawi zoposa 3.5 poyerekeza ndi njira zina. Ubwino wina wa kupukuta mchenga ndikuti kuuma pamwamba kumatha kudziwikiratu ndipo kumachitika mosavuta panthawi yoyeretsa.
ZokhudzaGalasi Lozizira
Kuzizira kumaphatikizapo kupangitsa pamwamba pa chinthu chosalala chomwe poyamba chinali cholimba, zomwe zimapangitsa kuti kuwala kuwonekere pamwamba. Mwa mankhwala, galasi limapukutidwa ndi makina kapena kupukutidwa ndi manja ndi zinthu zopukutira monga corundum, mchenga wa silica, kapena ufa wa garnet kuti apange pamwamba polimba mofanana. Kapenanso, yankho la hydrofluoric acid lingagwiritsidwe ntchito pokonza galasi ndi zinthu zina, zomwe zimapangitsa kuti galasi likhale lozizira. Posamalira khungu, kuchotsa khungu kumachotsa maselo akhungu akufa, zomwe zimathandiza koma siziyenera kugwiritsidwa ntchito mopitirira muyeso, kutengera mtundu wa khungu lanu. Kuchotsa khungu mopitirira muyeso kumatha kupha maselo atsopano asanapange nembanemba yodziteteza, zomwe zimapangitsa kuti khungu lofewa likhale losavuta kuopsezedwa ndi zoopsa zakunja monga kuwala kwa UV.
Kusiyana Pakati pa Galasi Lozizira ndi Lophwanyidwa ndi Mchenga
Kuzizira ndi kuphulika kwa mchenga ndi njira zopangira magalasi kuti aziwala, zomwe zimathandiza kuti kuwala kufalikira mofanana kudzera m'mithunzi ya nyali, ndipo ogwiritsa ntchito ambiri amavutika kusiyanitsa pakati pa njira ziwirizi. Nazi njira zenizeni zopangira njira zonse ziwiri komanso momwe mungazizindikirire.
Njira Yopangira Chipale Chofewa
Galasi lozizira limamizidwa mu yankho lokonzedwa la asidi (kapena lopakidwa ndi phala la asidi) kuti lidule pamwamba pa galasi kudzera mu kukokoloka kwa asidi wamphamvu. Nthawi yomweyo, hydrofluoric ammonia mu yankho la asidi wamphamvu imalimbitsa pamwamba pa galasi. Chifukwa chake, kuzizira bwino kumapangitsa kuti pamwamba pa galasi pakhale kosalala kwambiri komanso kufalikira kwa kristalo komanso kukhala ndi mdima. Ngati pamwamba pake pali powuma pang'ono, zimasonyeza kuti asidi wambiri wawonongeka pagalasi, zomwe zikusonyeza kuti mmisiriyo sanakule bwino. Zigawo zina zitha kukhalabe zopanda makristalo (omwe amadziwika kuti "osapanga mchenga" kapena "madontho agalasi"), zomwe zimasonyezanso luso losauka. Njira imeneyi ndi yovuta kwambiri ndipo imadziwika ndi kuwoneka kwa makristalo owala pamwamba pagalasi, omwe amapangidwa pansi pa mikhalidwe yovuta chifukwa cha kumwa hydrofluoric ammonia mwachangu.
Njira Yophulitsira Mchenga
Njira imeneyi ndi yofala kwambiri, pomwe chotsukira mchenga chimaponya mchenga mwachangu kwambiri pamwamba pa galasi, ndikupanga malo osalinganika bwino omwe amabalalitsa kuwala kuti apange kuwala kofalikira pamene kuwala kukudutsa. Zinthu zagalasi zomwe zimapangidwa ndi kutsukira mchenga zimakhala ndi mawonekedwe okhwima pamwamba. Chifukwa chakuti pamwamba pa galasi lawonongeka, galasi loyera poyamba limawoneka loyera likawonekera ku kuwala. Kuvuta kwa njirayi ndi kwapakati.
Njira ziwirizi ndi zosiyana kwambiri. Magalasi oundana nthawi zambiri amakhala okwera mtengo kuposa magalasi oundana, ndipo zotsatira zake zimadalira zomwe ogwiritsa ntchito amakonda. Mitundu ina yapadera ya magalasi si yoyenera kuundana. Poganizira za kufunafuna ulemu, magalasi oundana ayenera kusankhidwa. Njira zoundana ndi mchenga nthawi zambiri zimatha kupangidwa ndi mafakitale ambiri, koma kupeza magalasi abwino kwambiri oundana sikophweka.
