Ubushushu iiglasi ukumelana: iimpawu mveliso kunye Scope

Glass - omnye izinto elidala kunawo ngeendlela ezahlukahlukeneyo. iimveliso zeglasi yonke indawo, kodwa ngokuqhelekileyo musa ukucinga ukuba kakhulu malunga iimpawu zayo. Baya zingahluka ngokuxhomekeke ekusetyenzisweni ekujongwe iimveliso elizayo. Enye yezinto ezininzi eziqhelekileyo iindidi i iglasi ubushushu-proof. Makhe sibone indlela eyahluke ukusuka njengesiqhelo, yaye apho kuyimfuneko.

iglasi ubushushu-proof

Glass yinto into ezingaphiliyo. Lubonakala ngeempawu lolwelo eqinileyo, etyhidiweyo, yinto viscosity eliphezulu. ubu, amandla, ukuxinana, nangokuvutha yayo ngqo zahlukile kakhulu kwaye lixhomekeke ukungcola.

Kutsha nje, izinto ziye ziqulunqwe, nezithi ilifa iipropati zeglasi Nedlac, ezifana iyawulwa umlilo. eziphambili parameter ukuba yahlukile kwezinye ubushushu iglasi iglasi enganyangekiyo - lobushushu apho oluyigcinayo iipropati yayo. Oku uyakwazi ukumelana ubushushu nokuba 1000 degrees Celsius, ngoxa "asebenza 'yakhe ivale sele ngama-80.

Kwi refractoriness kuchaphazela ukwakhiwa kunye Ebubanzini eziphathekayo. Ukuba iglasi ziyatyeba kwaye onomlinganiselo ephezulu oxides kwealkali, kuya kuba ixesha elide. Kakhulu ukumelana ubushushu-ubungqina iglasi - zwi. Oku uyakwazi ukumelana utshintsho obushushu enkulu kwaye lobushushu ukubila eliphezulu (2230 degrees).

Ukuveliswa iglasi ubushushu-resistant

Ngokuqhelekileyo, iglasi ngumxube zinamacandelwana aliqela. Ukuthatha umgangatho izinto dust isanti, ikalika soda. Bona lashushu amaqondo obushushu aphezulu kakhulu (1700 ° C), kutheni kunyibilike kwaye oxutywe omnye nomnye. Emva koko, lo umxube batyhileka kulo tin olutyhidiweyo (ukuba lingadibananga ngenxa umahluko lexinene), yaye emva koko ngokuthe ngcembe zipholile.

Ukunika iimpawu eziyimfuneko adityaniswe la macandelo, kunye nezinye izinto. Ukwenza iglasi ubushushu-ubungqina, esebenzisa oxides ezahlukeneyo. Ngenxa yoko, xa borosilicate izinto iqulethe boron oxide a dust - oxide lesilicon.

amandla Okuninzi kuya kuba, ukuba usebenzisa kwiiseli ezininzi. Ukulungiselela le njongo akunikwe aphole. sheets Kugqityiwe ukuba sanded, ukuwuhlamba bahlabeka ubungakanani ezifunekayo. Ke inani iglasi sheets ukuba yesondo omnye komnye ngokusebenzisa Polymer okhethekileyo. Kubekho nokuyifeza touch litshiswayo iglasi "isonka" kwi degrees 660-680.

isicelo

Ubushushu glass ukumelana ithandwa ekhitshini. Ngenxa enokuba kubhaliwe wenza oveni kunye cookware. imveliso Common kwale nto nalo eziko. glass zwi ezisetyenziswa xa kusenziwa ifayibha enombala, lens Fresnel, crucibles, insulators, njalo njalo. D. Borosilicate zisetyenziselwa iindondo enombala, izitya, ebonisa yerediyo.

Xa impahla iglasi ubushushu-enganyangekiyo eziluncedo ezininzi. It ukumelana umlilo evulekileyo, ixesha elide. Le nto egalelwe ngokwaneleyo kwaye ayenzi oxidize xa itshiswa, ngoko ayitshintshi kwabhalwa izitya. Yena phantsi ngokudleka ukukalwa.

Kakade ke, nkqu iglasi ubushushu-ubungqina uye kuneengxaki. It modem ukukhula okanye ukuncipha lobushushu. Ezi zidlo ukusuka ezinjalo kufuneka akanakubekwa kwicala umlilo omkhulu ngoko nangoko emva efrijini. Ukongeza, iglasi engangenwa na yothuse-proof kuwisa yayo ikufanele.
