Unoziva here? Kunyangwe maziso asina kupfeka asingakwanise kupatsanura marudzi akasiyana egirazi, kutaura chokwadi, girazi rinoshandiswa pakugadzirachifukidziro chekuratidzira, dzine mhando dzakasiyana-siyana, zvinotevera zvinoreva kuudza munhu wese kuti angatonga sei mhando dzakasiyana dzegirazi.
Nekuumbwa kwemakemikari:
1. Girazi reSoda-lime. Rine huwandu hweSiO2, rinewo 15% Na2O uye 16% CaO
2. Girazi resimbi rakagadzirwa nearuminiyamu. SiO2 neAl2O3 ndizvo zvinonyanya kushandiswa
3. Girazi reQuartz. Zviri mukati meSiO2 zvinopfuura 99.5%
4. Girazi resilicone rakawanda. Huremu hweSiO2 hunosvika 96%
5. Girazi re silicate rine mutobvu. Zvinhu zvikuru zvinoshandiswa ndiSiO2 nePbO
7. Girazi reBorosilicate. SiO2 neB2O3 ndizvo zvinonyanya kushandiswa
8. Girazi rephosphate. Phosphorus pentoxide ndiyo chinhu chikuru
Nhamba 3 kusvika ku7 hadziwanzo shandiswa pagirazi rekuvharira, saka hapazove nepfungwa huru.
Nekushandisa nzira yekugadzira girazi:
1. Kugadzira magirazi anoyangarara
2. Kugadzira magirazi ekudhonza pasi-kudonha
Chii chinonzi kugadzira magirazi anoyangarara?
Nzira yacho inonyanya kunyungudutsa, kujekesa, kutonhodza mvura yegirazi iri pasi pekutonga kwegedhi rinotonga kuburikidza negwara rekuyerera, kuyerera kunoenderera mberi kuchipinda mugomba retini, kuyerera pamusoro pesimbi yakanyungudutswa, mvura yegirazi ichiyerera ichipinda mutangi retini mushure mekukanganiswa kwegiravhiti, kupukuta pasi pesimba repamusoro, kuyerera mberi pasi pedhiraivha huru yekudhonza, pasi pesimba remudhonzi kuti uwane maitiro ekutetepa kwebhandi regirazi, kugadzira girazi rakatetepa kwazvo. Nokudaro, kune divi retini nerutivi rwemhepo.
Chii chinonzi overflow down-draw glass performing?
Mvura yegirazi yakanyungudutswa inoiswa mumugero wakagadzirwa neplatinum palladium alloy, ichiyerera ichibuda mumugero uri pasi pemugero uye ichishandisa simba rayo rekukwevera pasi uye kudhonza pasi kugadzira girazi rakatetepa zvikuru. Ukobvu hwegirazi rinogadzirwa nenzira iyi hunogona kudzorwa zvichienderana nehuwandu hwekudhonza pasi, saizi yemugero uye mwero wekudonha kwechoto, nepo kudonha kwegirazi kuchigona kudzorwa zvichienderana nekugoverwa kwetembiricha kwakafanana, uye girazi rakatetepa zvakanyanya rinogona kugadzirwa nguva dzose. Saka, hapana divi resimbi kana divi remhepo.
3. Rudzi rwegirazi reSoda Lime
Nzira yekugadzirisa ndeyekuyerera, inozivikanwawo segirazi rinoyangarara. Nekuti rine huwandu hushoma hweioni dzesimbi, rinoita girini kubva kurutivi rwegirazi, saka rinozivikanwawo segirazi rebhuruu.
Ukobvu hwegirazi: kubva pa0.3 kusvika 10.0mm
Girazi reSodium calcium (kwete rese)
Zvinhu zvechiJapan: Asahi nitro (AGC), NSG, NEG nezvimwewo.
Zvinhu zvemumba: South Glass, Xinyi, Lobo, China Airlines, Jinjing, nezvimwewo.
Zvinhu zveTaiwan: Girazi reTabo.
Nhanganyaya yegirazi realuminium silicate rakakwirira, rinonzi girazi realuminium rakakwirira
4. Mazita akajairika
United States: Corning Gorilla Glass, igirazi realuminium silicate rakagadzirwa naCorning risingakuvadzi nharaunda.
Japan: AGC inogadzira girazi rine aruminiyamu yakawanda, tinoridaidza kuti girazi reDragontrail.
China: Girazi raXu Hong rine aruminiyamu yakawanda, rinonzi "Panda Glass"
Girazi reSaida rinopagirazi rekuvhara rekuratidzazvichienderana nezvinodiwa nevatengi uye mashandisirwo ezvigadzirwa, chinangwa ndechekupa sevhisi yepamusoro-soro yekugadzirisa magirazi pasi pedenga rimwe chete.
