Iyo huru yekuumbwa kwegirazi ndeye quartz (silica).Quartz ine mvura yakanaka yekudzivirira (kureva kuti, haigone kuita nemvura).Zvisinei, nekuda kwekunyungudika kwepamusoro (inenge 2000 ° C) uye mutengo wepamusoro we-high-purity silica, haikodzeri kushandiswa kweMisa kugadzirwa;Kuwedzera network modifiers kunogona kudzikisa nzvimbo yekunyungudika kwegirazi uye kuderedza mutengo.Common network modifiers sodium, calcium, nezvimwewo;asi network modifiers inotsinhanisa hydrogen ions mumvura, ichideredza kushomeka kwemvura kwegirazi;kuwedzera boron neAluminium inogona kusimbisa chimiro chegirazi, kupisa kwekunyunguduka kwakakwira, asi kudzivirira kwemvura kwakagadziridzwa zvakanyanya.
Mishonga yekurongedza zvinhu inogona kubata zvakananga zvinodhaka, uye hunhu hwavo huchakanganisa kuchengetedzwa nekugadzikana kwemishonga.Kune girazi remishonga, imwe yenzira huru yehutano hwayo ndeyekudzivirira kwemvura: iyo yakakwirira yekudzivirira kwemvura, inoderedza dambudziko rekuita nemishonga, uye yakakwirira yegirazi yemhando.
Zvinoenderana nekushomeka kwemvura kubva pasi kusvika kumusoro, girazi remishonga rinogona kukamurwa kuita: soda lime girazi, yakaderera borosilicate girazi uye yepakati borosilicate girazi.Mu pharmacopoeia, girazi rinoiswa muKirasi I, Kirasi II, uye Kirasi III.Kirasi I yemhando yepamusoro yeborosilicate girazi inokodzera kurongedzerwa kwemishonga yejekiseni, uye Kirasi III soda lime girazi rinoshandiswa pakurongedzerwa kweoral liquid nemishonga yakasimba, uye haina kukodzera mishonga yemajekiseni.
Parizvino, yakaderera borosilicate girazi uye soda-lime girazi zvichiri kushandiswa mudzimba girazi remishonga.Sekureva kwe "In-depth Research and Investment Strategy Report paChina's Pharmaceutical Glass Packaging (2019 Edition)", kushandiswa kweborosilicate mugirazi remishonga yemumba muna 2018 kwakangoita 7-8%.Nekudaro, kubva kuUnited States, Europe, Japan, neRussia vese vanoraira kushandiswa kweasina kwazvakarerekera borosilicate girazi kune ese majekiseni ekugadzirira uye biological gadziriro, yepakati borosilicate girazi yakashandiswa zvakanyanya muindasitiri yemishonga yekunze.
Pamusoro pekugadzika maererano nekudzivirira kwemvura, maererano nemaitiro akasiyana ekugadzira, girazi remishonga rakakamurwa kuita: mabhodhoro akaumbwa uye mabhodhoro anodzorwa.Bhodhoro rakaumbwa nderekupinza zvakananga girazi remvura muforoma kugadzira bhodhoro remushonga;nepo bhodhoro rekudzora riri rekutanga kugadzira girazi remvura muchubhu yegirazi, uye wocheka chubhu yegirazi kugadzira bhodhoro remushonga
Zvinoenderana neKuongorora Chirevo cheIndasitiri yeGirazi Packaging Zvishandiso zveMajekiseni muna 2019, mabhodhoro ejekiseni akaverengera makumi mashanu neshanu muzana egirazi remishonga uye ndechimwe chezvigadzirwa zvikuru zvegirazi remishonga.Mumakore achangopfuura, kutengeswa kwemajekiseni muChina kwakaramba kuchiwedzera, zvichifambisa kudiwa kwemabhodhoro ejekiseni kuti kurambe kuchikwira, uye shanduko yemitemo ine chekuita nejekiseni inofambisa shanduko mumusika wegirazi wemishonga.
