Galasi imagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana chifukwa cha kusinthasintha kwake. Kupatula zomwe zimagwiritsidwa ntchito kwambirizotengera zodzikongoletsera, imaphatikizapo mitundu yopangira zitseko ndi mazenera, monga magalasi opanda kanthu, magalasi opangidwa ndi laminated, ndi omwe amagwiritsidwa ntchito pokongoletsa zojambulajambula, monga magalasi osakanikirana ndi magalasi ojambulidwa.
Makhalidwe a Sandblasting
Kuphulika kwa mchenga ndi njira yomwe mpweya woponderezedwa umayendetsa ma abrasives pamwamba kuti athandizidwe. Amadziwikanso kuti kuwomberedwa kapena kuwomberedwa. Poyamba, mchenga ndi umene unkagwiritsidwa ntchito potupa, choncho njira imeneyi inkatchedwa kuti sandblasting. Kuphulika kwa mchenga kumakhala ndi zotsatira ziwiri: kumayeretsa pamwamba mpaka kufika pamlingo wofunikira ndipo kumapangitsa kuti pakhale roughness kuti kumamatira kumatira pa gawo lapansi. Ngakhale zokutira zabwino kwambiri zimavutikira kumamatira bwino pamalo osatetezedwa kwa nthawi yayitali.
Kukonzekera kwapamwamba kumaphatikizapo kuyeretsa ndi kupanga makulidwe ofunikira "kutseka" zokutira. Zopaka zamafakitale zomwe zimagwiritsidwa ntchito pamalo opaka mchenga zimatha kukulitsa moyo wa zokutira ndi nthawi zopitilira 3.5 poyerekeza ndi njira zina. Ubwino wina wa sandblasting ndikuti roughness ya pamwamba imatha kudziwidwiratu ndikutheka mosavuta pakuyeretsa.
ZaGalasi Wozizira
Kuzizira kumaphatikizapo kupangitsa kuti chinthu chosalala chikhale cholimba, zomwe zimapangitsa kuti kuwala kupangitse kuwala kowoneka bwino. M'mawu amankhwala, galasi imapukutidwa mwamakina kapena kupukutidwa pamanja ndi ma abrasives monga corundum, mchenga wa silika, kapena ufa wa garnet kuti apange malo owoneka bwino. Kapenanso, yankho la hydrofluoric acid lingagwiritsidwe ntchito pokonza galasi ndi zinthu zina, zomwe zimapangitsa galasi lozizira. Posamalira khungu, kuchotsa khungu kumachotsa maselo akufa, omwe ndi othandiza koma osagwiritsidwa ntchito mopitirira muyeso, malinga ndi mtundu wa khungu lanu. Kutulutsa khungu kwambiri kumatha kupha maselo ongopangidwa kumene musanapange kakhungu kodziteteza, ndikupangitsa khungu lonyowa kuti lisavutike ndi zoopsa zakunja monga kuwala kwa UV.
Kusiyanitsa Pakati pa Galasi Yozizira ndi Mchenga
Frosting ndi sandblasting ndi njira zopangira magalasi kuti aziwoneka bwino, zomwe zimapangitsa kuti kuwala kuziwalika mofanana kudzera muzithunzi za nyali, ndipo ogwiritsa ntchito ambiri amavutika kusiyanitsa pakati pa njira ziwirizi. Nazi njira zenizeni zopangira njira zonse ziwiri komanso momwe mungadziwire.
Frosting Njira
Galasi yozizira imamizidwa mu njira ya acidic yokonzedwa (kapena yokutidwa ndi phala la acidic) kuti ipangitse galasi pamwamba pa kukokoloka kwa asidi. Panthawi imodzimodziyo, hydrofluoric ammonia mu njira yolimba ya asidi imatulutsa galasi pamwamba. Chifukwa chake, kuzizira kochita bwino kumapangitsa kuti pakhale magalasi osalala kwambiri okhala ndi crystalline kumwazikana komanso kuwononga. Ngati pamwamba pa galasilo ndi lovuta kwambiri, zimasonyeza kukokoloka kwa asidi pagalasi, zomwe zimasonyeza kuti mmisiriyo sakukhwima. Ziwalo zina zithabe kukhala zopanda makhiristo (omwe amadziwika kuti "no sanding" kapena "magalasi magalasi"), zomwe zikuwonetsa kusapanga bwino. Njirayi ndi yovuta mwaukadaulo ndipo imadziwika ndi mawonekedwe a kristalo wonyezimira pamtunda wagalasi, womwe umakhala pansi pazovuta kwambiri chifukwa chakumwa kwa hydrofluoric ammonia.
Sandblasting Njira
Izi zimachitika kawirikawiri, pamene mchenga wa mchenga umawombera mchenga pamtunda wa galasi, kupanga malo abwino osafanana omwe amamwaza kuwala kuti apange kuwala pamene kuwala kukudutsa. Magalasi opangidwa ndi sandblasting amakhala ndi mawonekedwe okhwima pamwamba. Chifukwa galasilo lawonongeka, galasi loyang'ana poyamba limawoneka loyera likakhala ndi kuwala. The ndondomeko zovuta mlingo ndi avareji.
Njira ziwirizi ndizosiyana kotheratu. Galasi yozizira nthawi zambiri imakhala yokwera mtengo kuposa galasi lopukutidwa ndi mchenga, ndipo zotsatira zake zimatengera zomwe amakonda. Mitundu ina yapadera ya magalasi si yoyenera kuzizira. Kuchokera pakuwona kufunafuna ulemu, galasi lozizira liyenera kusankhidwa. Njira zopangira mchenga nthawi zambiri zimatheka ndi mafakitale ambiri, koma kupeza magalasi abwino kwambiri sikophweka.
