Heat nemishonga muchionioni mukugadzira zvinhu uye Makuriro

Glass - mumwe mukuru uye seanokwanisa kuita zvinhu zvizhinji zvokuvakisa. Glass zvigadzirwa zvose zvakatipoteredza, asi kazhinji yatisingafungi zvakawanda pamusoro zvachiri. Vanogona siyana zvikuru zvichienderana nechinangwa kushandiswa ramangwana zvigadzirwa. Chimwe chezvinhu zvakafanana marudzi ari kupisa-uchapupu rinoonekera. Ngationei sei zvakasiyana zvatinosiita, uye apo zvinoshanda.

kupisa-uchapupu magirazi

Glass chinhu inorganic fuma. It kunoratidzwa ehupfumi ane yakasimba, yakaumbwa mvura, ndiko kumusoro viscosity. Its fragility, simba, arambe achirema, uye yakananga kupisa zvinosiyana zvikuru uye kuvimba netsvina.

Nguva ichangopfuura, zvinhu zvakatangwa iyo nhaka atypical magirazi ehupfumi, akadai moto nemishonga. The chikuru parameter kuti rakasiyana nemamwe regirazi kupisa nemishonga magirazi - tembiricha panguva iyo anoramba ehupfumi ayo. It angakudzivisai kupisa kunyange 1000 Celsius, apo ake "nevamwe" kutsemuka kare panguva madhigirii 80.

On refractoriness sei murwiyo uye pakukora mashoko. Kana girazi mukobvu uye rine dziine alkali oxides, zvichava yakasimba. Most nemishonga kupisa-uchapupu magirazi - Goldstone. It angakudzivisai guru tembiricha kuchinja uye ane yakakwirira Kubika tembiricha (2230 madhigirii).

Kugadzirwa kupisa nemishonga magirazi

Kazhinji, magirazi musanganiswa anoverengeka zvinoriumba. Kutora mwero zvinhu silica jecha, madota uye pasoda. Ivo vanotsamwira yakakwirira chaizvo tembiricha (1700 ° C), nei vari yakanyauka uye aivhengana. Zvadaro, musanganiswa dzakadururwa kupinda yakaumbwa gaba (havana kuvhenganiswa nokuda arambe achirema musiyano), uye ipapo zvishoma nezvishoma haachandidi.

Kupa zvakafanira ehupfumi kuti zvinoriumba aya vakawedzera, uye zvimwe zvinhu. Kuti kupisa-uchapupu regirazi, uchishandisa oxides siyana. Saka, muna borosilicate zvinhu rine Boron oxide ari silica - nesilicon oxide.

More simba zvichataurirana, kana mukashandisa akaturikidzana akawanda. Nokuti chinangwa ichi kwakapiwa zvichitonhorera zvachose. Finished machira vari sanded, vakachenesa uye akatema kuti zvaida kukura. Ipapo nhamba regirazi machira vari waakaita mumwe achishandisa rinokosha polymer. The Kupedzwa kubatwa unopfuta girazi "sangweji" pa 660-680 inegumi.

kunyoresa

Heat nemishonga girazi kwakakurumbira mukicheni. Nokuti chinoitwa yamavira uye cookware. Common chigadzirwa ichi acho ariwo choto. Goldstone girazi rinoshandiswa zvaAtemisi Manyiminya faibha, mumwe Fresnel izvo, crucibles, insulators, uye zvichingodaro. D. Borosilicate kushandiswa Manyiminya magirazi, ndiro, achiratidza teresikopu.

In nemidziyo nokupisa nemishonga magirazi mikana yakawanda. It unopikiana kunyange moto rakavhurika, ndizvo vafuke. Mashoko acho zvakakwana inert uye asingauyi oxidize kana pakutsamwisana saka hazvichinji yeshoko ndiro. Haasi pasi ngura uye scaling.

Chokwadi, kunyange nokupisa-uchapupu magirazi ane zvainovhiringidzawo. Hazvina sei unopinza kuwedzera kana kutapudza kupisa. Ndiro kubva zvinhu zvakadaro hazvifaniri kupfeka moto guru pakarepo mushure furiza. Uyewo, fireproof girazi hauna kuvhundutsa-uchapupu udonhedze yayo kufanira.
