Heat resistant gilashin: Manufacturing fasali da kuma bigiren

Glass - daya daga cikin mafi tsufa kuma mafi m kayan. Glass kayayyakin ne duk kewaye da mu, amma yawanci ba mu zaton yawa game da halaye. Sun iya bambanta ƙwarai dangane da nufin yin amfani da gaba kayayyakin. Daya daga cikin mafi kowa iri ne mai zafi-hujja gilashi. Bari mu gano yadda shi ya bambanta daga saba, da kuma inda m.

zafi-hujja gilashi

Glass wani inorganic abu. An halin Properties na wani m, zubi ruwa, shi ne wani babban danko. Its fragility, ƙarfi, yawa, da kuma takamaiman kadan bambanta da kuma dogara a kan impurities.

Kwanan nan, kayan da aka ɓullo da wanda mallaka atypical gilashin Properties, kamar wuta juriya. Babban siga cewa ne daban-daban daga wasu gilashin zafi resistant gilashi - da yawan zafin jiki a wadda ta kula da kaddarorin. Yana iya jure zafin rana ko 1000 digiri Celsius, yayin da "abokan aiki" crack riga at 80 digiri.

A bijirewarsu shafi cikin abun da ke ciki da kuma kauri daga cikin abu. Idan gilashin ne thicker kuma ƙunshi mafi girma rabo daga Alkali oxides, shi zai zama m. Mafi resistant zafi-hujja gilashi - ma'adini. Yana jure manyan zazzabi canje-canje da kuma yana da babban tafasar zazzabi (2230 digiri).

Production na zafi-resistant gilashi

Yawanci, da gilashi ne a cakuda da dama aka gyara. Don dauki wani misali abu silica yashi, lemun tsami da kuma soda. Suna mai tsanani zuwa sosai high yanayin zafi (1700 ° C), da yasa suka narke, kuma gauraye da juna. Bayan nan, cikin cakuda da aka zuba a cikin zubi tin (da suka ba su gauraya saboda da yawa bambanci), sa'an nan a hankali sanyaya.

Don bayar da zama dole Properties to wadannan aka gyara an kara da cewa, da kuma sauran abubuwa. Don yin zafi-hujja gilashi, ta amfani da daban-daban oxides. Saboda haka, a borosilicate abu ya ƙunshi boron oxide a wani silica - silicon oxide.

More ƙarfi shi zai yi, idan ka yi amfani da dama yadudduka. A saboda wannan dalili shi ne ba su kwantar gaba daya. Gama zanen gado suna sanded, tsabtace da kuma yanke zuwa da ake buƙata size. Sa'an nan a yawan gilashin zanen gado suna bonded zuwa juna ta wajen wani musamman polymer. A karewa touch aka kona gilashin "sanwic" a 660-680 digiri.
