Munzanga yemazuva ano, vanhu vanofanira kushandisa zvigadzirwa zvegirazi zvakawanda muhupenyu hwavo hwezuva nezuva, uye hazvigoneke zvachose kubvisa girazi. Girazi rakagadzikana, rinodzivirira maasidhi akasimba uye alkalis, uye rakaoma uye rinogara kwenguva refu. Ndiro rimwe rezvinhu zvakakosha pakushandisa michina inonyanya kukosha. Unoda kudzidza zvakawanda nezvekuti girazi rinokweshwa sei uye kuti rinokweshwa sei? Ngatizvionei pamwe chete!
Ndedzipi nzira dzekupukuta girazi?
Nzira 1: Kupukuta Moto
Kushandiswa kwemurazvo kupfavisa pamusoro pegirazi uye simba remoto pagirazi kunogona kubvisa zvimwe zvinhu pamusoro pegirazi, asi kupfava kwepamusoro pegirazi mushure mekugadzirisa kuchaderera. Kazhinji, muromo wegirazi rine gomba rakakora mushure mekucheka, uye nzira iyi inogona kushandiswa pakupukuta.
Girazi rinoshandiswa: girazi resoda lime, girazi resilica rinoputika zvakanyanya.
Nzira yechipiri: Kupolisha Kupolisha Upfu
Kukweshana kwepolish powder pamusoro pegirazi kunoshandiswa kubvisa mavanga, izvo zvinogona kuwedzera kupenya kwechiedza uye refraction effect yegirazi. Musati mapolish, chikamu chakapolishwa chinofanira kucheneswa nebhandi rinokwesha, uye pure plane inofanira kukweshwa ne 400-mesh emery abrasive disc. Kune maturusi akawanda nezvinhu zvinoshandiswa pakuita nzira iyi yekukwesha, asi mhedzisiro iri nani i cerium oxide yewool wheel.
Girazi rinoshandiswa: ruzhinji rwezvigadzirwa zvegirazi.
Nzira 3: Kupukuta Asidhi
Pamusoro pegirazi panogadziriswa neacid inokuvadza girazi. Risati rapukutwa, pamusoro pegirazi panofanirawo kupukutwa nemabhandi anokwenya, nekuti kupukutwa neacid kunogona kuderedza ukobvu hwegirazi zvakanyanya, asi rinogona kusakwanisa kubvisa mitsetse yese yegirazi.
Girazi rinoshandiswa: chero girazi (asi mhedzisiro mushure mekukwesha inotsanangurwa negirazi pacharo).
Matanho ekupukuta girazi
1. Kuchenesa nekugadzira pamusoro pegirazi usati wapukuta girazi
(1) Tanga watenderedza mupendero wegirazi kuti rigadziriswe netepi kudzivirira kusvibisa nharaunda yakapoteredza kana girazi rapukutwa.
(2) Chenesai pamusoro pegirazi nepepa rekupukuta regirazi nokungwarira, uye hapafanirwe kunge paine guruva, jecha, nezvimwewo zvakabatanidzwa.
(3) Girazi risati rapukutwa, shandisa chiratidzo kutenderedza chikamu chinofanira kupukutwa uye kugadziriswa kumashure kwegirazi kuti risatsvedze uye zvichiita kuti nzvimbo yekupukutwa ive yakakura zvakanyanya.
2. Shandisa girazi reP120#, P240#, P400#, P600#dhaimani sandpaperkuchenesa mavanga egirazi
(1) Cherechedza kuti muenzaniso wepepa remasandpaper pano wakasiyana newepepa remasandpaper rinokandirwa nemaoko zuva nezuva, uye haugone kusanganiswa nepepa remasandpaper ezuva nezuva.
(2) Dururirai zvishoma zvemushonga wekupukuta kana zvichidikanwa, musanganise nemvura nechiyero che1:1, kwete kupfuura 1:5, uye inoshandiswa zvakanyanya pakupukuta nesandpaper.
(3) Iva nechokwadi chekuti mvura yekupukuta yakakwana panzvimbo yekupukuta, uye sandpaper haigone kukuyiwa zvakananga pamusoro pegirazi chero nguva.
①Kukwenya kwakadzama: tanga washandisa P120# girazi sandpaper pakukuya kwekutanga, wobva washandisa P240# kuti rinyatsotsvedzerera, uye pakupedzisira shandisa P600# sandpaper kuti uikwenye zvakare kuti pamusoro payo pakwane zvinodiwa pakukwenya. Unogonawo kusiya chinhu ichi woenda zvakananga padanho rechitatu.
②Kukwenya kudiki: Shandisa P400#mapedhi emaoko edhaimani egirazi, wobva washandisa P600# sandpaper kuti uipukute zvakare kuti pamusoro payo pakwane zvinodiwa pakupukutesa. Unogonawo kusiya chinhu ichi woenda zvakananga padanho rechitatu.
3. Tsiva woisa mushonga wekupukuta woshandisa vhiri rekupukuta rakakosha kupukuta nekudzoreredza kujeka kwegirazi.
(1) Pukuta girazi woongorora kukuya kwesandpaper, isa mushonga wekupukuta uye shandisa vhiri rekupukuta rakakosha (nekudzvanywa kwakakodzera, tireyi yemuchina wekupukuta nepamusoro pegirazi zvinofanira kunge zvakati sandara). Kana pasina muchina wekupukuta, unogona kupukuta nepepa rekupukuta nemaoko. Chenjerera kuti usafambe nekukurumidza panguva ino, uye pukuta zvakanaka kuti uve nechokwadi chekuti zvinobuda.
(2) Kana kupenya kusina kunaka, dzokorora matanho ari pamusoro apa
Zvinhu Zvinoda Kutariswa: Kunyange zvazvo kukwenya kwepamusoro-soro kwakadzama kupfuura ma microns zana kuchigona kubviswa nekukwenya, kunokanganisa mashandiro ekuchengetedza kwegirazi mushure mekukwenya. Kunyanya, kukwenya kwakadzama kupfuura ma microns zana pawindscreen yepamberi yemotokari hakuna kukodzera kukwenya.
Pfupiso ndeiyi: jecha rekutanga rakanyorova rinechivharo chekuchekesa madhaimanikubvisa mavanga zvishoma nezvishoma, wobva washandisa mapedhi ekupukuta nemvura yekupukuta kuti uchenese uye uvheneke.
