Borosilicate ingilazi: kwebalingisi, ukukhiqizwa nokusebenzisa

Sekuyisikhathi eside Ukunika ngezinto zesintu izici ekhethekile kwaba umkhuba ovamile. Imikhiqizo izakhiwo ngcono ukuvikelwa amakhemikhali, ubulukhuni anda futhi ukushisa ukumelana asetshenziswa wobunjiniyela, isiqoqi sama-softwe, zokwakha kanye nakweminye imikhakha. Akukona ahlale ngaphandle ukunakwa ezinciphisa ububanzi imikhiqizo efanayo ukumelana nomlilo. Ngakho, kusetshenziswa kakhulu e-imithi borosilicate ingilazi, tableware okuyindawo uhluke kalula isicelo futhi ububanzi elikhulu isithiyo izakhiwo.

Ukwakheka ingilazi

izakhiwo Technical nezingokwenyama izinto zinqunywa izici ezimbili - icubungula nqubo ku senqubo yokukhiqiza kanye izingxenye eziyinhloko zegazi. Ngokwengxenye enkulu, lokhu ingilazi kuyinto umelele iqembu abavamile silicate izinto, okuncike oxides. Lolu uhlu eziyisisekelo izingxenye kuhlanganise sodium carbonaceous, Silica yesihlabathi calcium oxide, okuyi-limestone. Kulokhu, borosilicate ingilazi libhekene khona ukwakheka kanye enye ingxenye, ebalulwe eziningi izinga angajwayelekile isakhiwo. Inani silicate Ukwakheka sengezwe boron oxide, futhi enikeza ukungawi ingilazi okushisa. Yiqiniso, kule ingilazi Ukwakheka yesimanje akugcini, njengoba amasethi izakhi Ushintshe su, ukugxila nezimfuneko ezithile imikhiqizo yokugcina.

inqubo-Glass Ukukhiqiza

Indlela jikelele kokwenza izinto borosilicate efana ubuchwepheshe yokukhiqiza izibuko ezivamile. Phakathi ukupheka esitofini main ncibilika lokubolekwa zisetshenziswa nge lokushisa ezingaphezu kuka 1300ºC. kumiswa mass Liquid is on metal panel ekhethekile. Ngokusho inqubo inqubo iflothi wenziwa borosilicate ingilazi ishidi usayizi inikezwe. Isici le ndlela wukuthi amashidi etholwe kungukuthi usike nhlobo futhi kungukuthi ukulungiswa, futhi ifomu eseqedile ezisetshenziswa umsebenzisi sekupheleni.

Kulezi izibuko kamuva wabizela ndawonye ama-emafasiteleni, eminyango, futhi, kwezinye izimo, futhi izinhlelo zokuvikela. Ingxenye enkulu amabhizinisi wahlanganyela ukukhiqizwa izibuko enjalo, igxile womshini izitsha isiqedile. Lokhu kungaba amashubhu, iziqukathi, wayithela ezitsheni; ezinye izinto ezisetshenziswayo yocwaningo lwezempilo bokusebenza izikhungo. Ukwenziwa ekhethekile imishini ukuzisika mechanical ingots wokucwebezelisa kuyiphi kamuva kuvela laboratory glassware ngeendlela ezihlukeneko. Empeleni, umehluko oyinhloko we impahla yokukhiqiza of the ezivamile silicate analogue iyona inhlangano ukuhamba komsebenzi ngo lokushisa eliphakeme.

izici eziyinhloko ingilazi

Glass yalolu hlobo kunenzuzo ezakhiweni eziningi kanye nokusebenza izici. Lena ngokuyinhloko ebanzi lokushisa uhla imvelo lapho ingilazi ingasetshenziswa. Njengoba standard, indaba ongakwazi ukumelana namazinga okubanda phansi -80ºC futhi 525ºC ezingeni ukushisa. Kusukela iphuzu zokusebenza umbono kwizimo zamalabhorekthi kwasekuqaleni lapho has ukumelana kuhlasela zamakhemikhali. It sinikezwe izimfanelo ezinjalo, tube wezokwelapha. Borosilicate ingilazi nge inertia yayo kwanele ukuthi umsebenzisi angakwazi thembeke ukuvikela okuqukethwe acid, nosawoti, alkalis, futhi organic compounds. Kuyaqapheleka futhi amandla mechanical into. Njengoba Coefficient ukuminyana izisekelo borosilicate ephakeme kunaleyo izibuko silicate, kungcono bavikelekile ingozi umonakalo ngokomzimba. Ngaphezu kwalokho, imiphumela enamandla ezishisayo ungabhubhisi ebusweni ingilazi yaba izicucu, waqhumuka panel lapho akhiwa futhi uvikelekile onqenqemeni blunt.

Osayizi kanye okukhipha ifomethi

izitsha ezikhethekile kuvame ekhiqizwa oda labs namabhizinisi wezokwelapha. Nokho, ukukhiqizwa ishidi izinto ukunikeza abanye amazinga ukukhululwa. Ikakhulu, i-ukushuba iphaneli ingilazi kungenzeka 6-12 mm. Lapho leli phutha uqobo esingaphansi 0.3 mm. Isayizi, lapho ishidi senziwa ingilazi ukushisa ukumelana, emelelwa usayizi Uhlaka 150h300 abone. Kodwa, futhi, ngesicelo, izinkampani eziningi khona amakhono kwezobuchwepheshe kanye ekwandiseni kwemigomo ukukhiqizwa. Kepha inani eliphansi ke kubhekwe ukuba ifomethi 10x10 cm, iyunithi owesincane ukukhululwa kwe ingilazi.

Fields of kwesicelo

Njengoba sekuphawuliwe kakade, izici impahla kangcono ukusetshenziswa laboratories, imishini kwezokwelapha amakhabethe, njll Ngezinhloso ezinjalo, abakhiqizi ukukhiqiza flasks, iziqukathi, amashubhu kanye neminye imikhiqizo. I tube Ukuhluleka borosilicate ingilazi, ngaphandle izici ezikhethekile ezingokomzimba, futhi inesimiso kwesakhiwo. Nakuba kungase okukha phezulu sengathi tube, eqinisweni bobabili, futhi akha cleaner. Siyobona isicelo futhi eshidini lalo ingilazi zalolu hlobo. Ivame esetshenziswa njengoba ngodonga kwezobuchwepheshe optical futhi kuhlomisa izakhiwo labanetihibe zokuzivikela.

Fire lokulwa borosilicate ingilazi

izimfanelo ukumelana umlilo lwesayensi okusezingeni eliphezulu ikakhulukazi - esinye sezici ayisihluthulelo borosilicate impahla. Abakhiqizi ukukhiqiza panel okukhethekile elicwebezelayo kanye umnyango kudivayisi nokubuka amawindi imidwebo nge high izakhiwo zokuzivikela. Ngakho, ngokwesibonelo, glazing spider akuyona kuphela umlilo izakhiwo ukumelana kodwa futhi amandla lokukhanda. Iqoqo eliphelele indinganiso iwindi plastic izinhlelo futhi wasebenzisa ingilazi ukushisa ukumelana, ekuvikeleni ezishisayo. esiphelweni Elungisiwe nelangabi izinto ukumelana for the design of ophahleni kanye phansi evele.

Imikhawulo ukusetshenziswa ingilazi

Naphezu anhlobonhlobo nenzuzo izakhiwo lobuchwepheshe, imikhiqizo borosilicate babe ezinye nemingcele yokusebenzisa. Ngokuphathelene ukuxhumana nge ilangabi evulekile, indaba uyakwazi esaziwa umlilo akuyona isikhathi esingaphezu kwehora. Lokhu ehilelekile akuyona evumela ukusetshenziswa ingilazi enjalo kumagumbi nezimfuneko ekhethekile ukuphepha umlilo. Kukhona imikhawulo kwezinye izinhlelo zokusebenza. Ikakhulukazi, i-laboratory glassware ayikwazi ukumelana contact nge-acid hydrofluoric futhi hydrofluoric. Kubathinta kabi amashubhu test futhi flasks ne alikhali caustic, umphumela lapho ligcizelelwa lokushisa eliphezulu. Ngu uqobo, eshisa kakhulu ngeke kuyilimaze ingilazi, kodwa umehluko abukhali ungavumeli impahla ukuzivumelanisa isakhiwo isikhathi.

isiphetho

imikhiqizo Borosilicate ingilazi akufanele kuthathwe njengendlela material ekhethekile sokuvikelwa okubhekiswe ekuhlaselweni zamakhemikhali umlilo. Singasho ukuthi akulutho ngisho ukusekela izici ukuthi abelwe ukuthuthukisa Ukusebenziseka imikhiqizo bendabuko. Nokho, borosilicate ingilazi, ngaphandle izimfanelo zokuzivikela, izitolo nezindawo ezifana obala kanye ne-transmission ukukhanya. Ngakho-ke, inhlanganisela yamandla mechanical, ukumelana umlilo futhi impahla ayevumela kubhekwe njengento ehlukile. Okungenani izitsha ezifana laboratory, okuyinto, ngaphezu izici ezingenhla, Ubuye inertness elikhulu.
