Yakanakisa girazi kuita, inogona kushandiswa mune dzakasiyana siyana zviitiko.Mukushongedza kwemukati, girazi rakapendwa uye girazi rinopisa rinogona kushandiswa, uye chimiro chinoshanduka;Muchido chekuchengetedza nguva dzekuchengetedzwa kwemunhu dzakakodzera girazi rakanyoroveswa, girazi rakashongedzwa uye mamwe girazi rekuchengetedza;Inoda kugadzirisa kupenya, kana uchidzivirira kuvanzika kunogona zvakare kushandisa girazi rakanyungudutswa negirazi rinopenya, riri nyore uye rinogara.Kuti unzwisise maitiro makuru ekugadzirwa kwebhodhoro regirazi uye maitiro ekuudza bhodhoro rakanaka regirazi kubva kune rakaipa, ona pazasi.
1. Kuongororwa kwegirazi pepa
Chitarisiko chemhando inonyanya kutarisa kutsvedzerera, kuona kana paine mabubbles, inclusions, zvikwenya, mitsetse uye mhute mavara uye humwe hurema hwemhando, pane zvikanganiso zvakadaro zvegirazi, mukushandiswa kuchave kuremara, kuderedza kujeka kwegirazi, simba remagetsi uye kupisa. kugadzikana kwegirazi, engineering haifaniri kusarudzwa.Nemhaka yokuti girazi chinhu chakajeka, mukusarudzwa kwekuongorora kwekuona, unhu hunokosha hunogona kuonekwa.Kuongororwa kwezvigadzirwa zvegirazi zvekugadzira magirazi, kunze kwekuongororwa kwegirazi rakatsetseka zvinodiwa, kunofanirwawo kuyedza kunaka kwayo kwekugadzirisa, kutariswa kwekutarisa uye saizi zvakajairwa, kugadzirisa kurongeka uye kujekesa kwedhizaini kunosangana nezvinodiwa, nepo divi risingabvumirwe kuve risina kukwana.Hunhu hwekunze hwegirazi girazi zvidhinha hahubvumiri kutsemuka, mu vitreous muviri haubvumire opaque kusanyungudika zvemukati, usatendera kusanganiswa pakati peviri vitreous muviri uye glue kugashira zvisingadiwe.Nekuona, muviri wezvidhinha unofanirwa kunge usina corrugations, mabhuru uye mitsetse yakaturikidzana inokonzerwa nemuviri wegirazi usina kuenzana.Concave mukati mekunze hombe yezvidhinha zvidhinha inofanirwa kunge isingasviki 1 millimeter, kunze convex kunofanirwa kunge isingasviki 2 millimeter, huremu hunofanirwa kuenderana nemhando yemhando, husina hurema hwemhando senge kutenderera kwepasi uye gap, burr, Angle inoda. muvambi.
2. Teerera inzwi.Ruzha rwaunonzwa paunorova girazi bhodhoro neruoko rwako rwakasiyana.
3. Zvechokwadi, kana tichida kuratidza kana bhodhoro regirazi rakakodzera kana kwete, isu tichiri kuda kuita mimwe miedzo, asi isu hatigoni kuzviita muupenyu hwezuva nezuva.Tinogona kunyatsoona kunaka nekutonga chitarisiko.
