Heat resistant glass: izici yokukhiqiza kanye Ububanzi

Glass - yezinto endala futhi enza izinto ezihlukahlukene kakhulu. imikhiqizo Glass yonke indawo, kodwa ngokuvamile singazi kakhulu ngayo izici zayo. Abakwazi kuyahlukahluka kuye ngokuthi ukusetshenziswa okuhloswe imikhiqizo esizayo. Omunye lwezinhlobo ezivame kakhulu kuyinto ingilazi ukushisa-ubufakazi. Ake sithole ukuthi kwakungani ukuthi lihluke kanjani evamile, futhi lapho kudingeka khona.

ingilazi ukushisa-ubufakazi

Glass nemiyo wezinto ezingaphili. It libhekene izakhiwo okuqinile, uketshezi ezibunjiwe, it is a viscosity okusezingeni eliphezulu. Its fragility, amandla, ukuminyana, futhi ukushisa ethize ayahlukahluka futhi ancike amanyela.

Muva nje, izinto eziye zasungulwa okuyinto ifa atypical ingilazi izakhiwo, ezifana umlilo ukumelana. Umngcele we-main ukuthi ihlukile kwezinye ingilazi ukushisa resistant glass - izinga lokushisa lapho ke igcina impahla yayo. Kungaba ukumelana ukushisa ngisho 1000 degrees Celsius, kanti "nozakwethu" yakhe ukwambula kakade degrees 80.

On refractoriness kuthinte ukwakheka kanye ukushuba we impahla. Uma ingilazi mkhulu futhi iqukethe inezinga eliphakeme oxides alikhali, kuyoba okuhlala isikhathi eside. ukumelana kakhulu ukushisa-ubufakazi ingilazi - asebenza ngebhethri. Kungaba ukumelana izinguquko ezinkulu lokushisa futhi ukubila lokushisa eliphezulu (2230 degrees).

Ukukhiqizwa ukushisa-resistant glass

Ngokuvamile, ingilazi inhlanganisela izingxenye eziningana. Ukuthatha ejwayelekile Silica impahla isihlabathi, lime soda. Basuke ukufuthelana okushisa aphezulu kakhulu (1700 ° C), kungani elicibilikile yayihlangana. Ngemva kwalokho, ingxube elachithwa ku ithini oncibilikisiwe (kungukuthi elixutshwe ngenxa umehluko kwabantu), bese kancane kancane selehlile.

Ukunikeza izakhiwo ezidingekayo ukuze lezi zingxenye kunezelwa, kanye nezinye izinto. Ukuze wenze ingilazi ukushisa-ubufakazi, usebenzisa oxides ezahlukene. Ngakho, ngo-borosilicate impahla iqukethe boron oxide endaweni Silica - nitrous silicon.

amandla angeziwe ke kuyodingeka, uma usebenzisa izingqimba eziningana. Ngenxa yale njongo Niphiwe kuphole. amashidi Iphele kuthiwa sanded, bahlanza futhi uthathe usayizi edingekayo. Khona-ke eziningi ingilazi amashidi zihlanganiswa komunye nomunye esebenzisa i-polymer ekhethekile. I touch yokuqedela kuyalivuthela ingilazi "isangweji" at 660-680 degrees.

isicelo

Heat resistant glass kuyaziwa ekhishini. Ngoba kwenziwa Ohhavini kanye Cookware. umkhiqizo Common kwale nto futhi iziko. Quartz ingilazi asetshenziswe ekukhiqizeni fibre optical, lens Fresnel, crucibles, insulators, nokunye. D. Borosilicate esetshenziselwa izibuko optical, izitsha, khomba isibonakude.

Ngo izinto izinzuzo eziningi ukushisa-resistant glass. Imelana ngisho umlilo evulekile, okuhlala isikhathi eside. Indaba ngokwanele inert futhi akusho oxidize lapho evuthayo, ngakho lokhu akulishintshi ukunambitheka izitsha. Akayena kuncike ukugqwala futhi uyakekela.

Yiqiniso, ngisho ingilazi ukushisa-ubufakazi has nemiphumela ethile engathandeki. It akasabeli waba ukwanda okukhulu noma wehlise izinga lokushisa. Izidlo kusuka izinto ezinjalo akufanele wagqoka umlilo omkhulu ngokushesha ngemva efrijini. Ngaphezu kwalokho, ingilazi engangenwa umlilo akuyona ukwethusa-ubufakazi bese uphonsa zayo zinkulu.
