Kuumbwa kukuru kwegirazi ndeye Quartz (Silica). Quartz ine yakanaka kudzikiswa kwemvura (ndiko kuti, hazvisizvo nemvura). Nekudaro, nekuda kwekunyungudika kwakadzika kwekunyungudika Kuwedzera network modifiers kunogona kuderedza iyo yekunyungudika yegirazi uye kuderedza mutengo. Zvakajairika network modifiers is sodium, calcium, nezvimwewo.; Asi iyo network modifiers ichachinjana hydrogen ions mumvura, ichidzora kudzikisira kwemvura yegirazi; Kuwedzera Boron naLuminium kunogona kusimbisa chimiro chegirazi, tembiricha yekunyungudika yasimuka, asi kupokana kwemvura kwave kwakaitwa zvakanyanya.
Zvishongedzo zvechiremba zvekutakura zvinogona kutaurirana zvakananga zvinodhaka, uye hunhu hwavo huchabata kuchengeteka uye kugadzikana kwemishonga. Nezvegirazi remishonga, imwe yemhando huru yemhando yayo ndeyekudzivisa kwemvura: Iyo yepamusoro kudzikisira kwemvura, iyo yakaderera njodzi yekuita nemishonga, uye yakakwira mhando yegirazi.
Zvinoenderana nekudzikisira kwemvura kubva kuderera kusvika pakakwirira, girazi rekurapa rinogona kukamurwa kuita: Soda lime girazi, Low Borosilrate girazi uye pakati pegirorosi. MuPharmacopeia, girazi rakarongedzwa mukirasi ini, kirasi II, uye kirasi III. Kirasi Ini High-mhando Bolortid Girazi yakakodzera pakurongedzwa kwemishonga yejekiseni, uye kirasi III Soda lime inoshandiswa pakurongedzwa kwemuromo uye mishonga yakasimba, uye haina kukodzera mishonga yejekiseni.
Parizvino, yakaderera borosilrate girazi uye girazi-lime-lime girazi richiri kushandiswa mune yegirazi rechikadzi rechikadzi. Maererano ne "pakadzika kutsvagurudza uye Investment Spection Nekudaro, kubva kuUnited States, Europe, Japan, uye Russia zvese zvakavanzika zvegiriyamu gadziriro yezvose gadziriro uye gadziriro dzepakati, dzepakati pegirasi dzave kushandiswa muindasitiri yekune dzimwe nyika.
Pamusoro pekuratidzwa maererano nekupokana kwemvura, maererano nemaitiro akasiyana ekugadzira, girazi rekurapa rakakamurwa mu: Mabhodhoro akaumbwa uye mabhodhoro anodzora. Bhodhoro rakaumbwa ndere kujekesa zvakananga girazi remvura mune iyo mold kuita bhodhoro rekurapa; Ipo bhodhoro rekutonga riri kutanga kuita girazi remafuta mune girazi tube, uye wobva wacheka iyo girazi tube kugadzira bhodhoro rekurapa
Zvinoenderana neyekuongorora kwedanda reindasitiri regirazi rekuputika kwemajekiseni mu1958% yegirazi rakazara regirazi uye ndeimwe yezvigadzirwa zvikuru zvegirazi rechirimo. Mumakore achangopfuura, kutengesa kwejekiseni muChina vakaramba vachikura, vachityaira kudiwa kweMabhodhoro ejekiseni kuti varambe vachikwira, uye shanduko mumarongero emajekiseni ane chekuita nemusika wegirazi.
