Maitiro ekushandisa uye kuchengetedza iyo quartz chubhu mune muffle choto

1. Nzvimbo yekunyorovesa yequartz tube ndeye 1270 degrees, uye haifaniri kudarika maawa matatu kana inoshandiswa pa 3 degrees.

2. Chengetedza chubhu yevira yakachena uye yakachena. Panofanira kunge pasina zvinhu zvakasara zvinosangana neSiO2 muchubhu yevira. Paunenge uchipisa zvinhu, kuitira kuti huni yehuni hurebe hupenyu hwebasa, usaisa zvinhu zvakananga pachubhu yechoto uye shandisa crucible yakaita sechikepe kuti uibate.

3. Mumamiriro ezvinhu akajairika, hazvikurudzirwi kuti vatengi vapfuure hydrogen muchoto chechubhu. Kunze kweiyo isiri-haidhirojeni yemukati muganho inoputika, kana mutengi achida kushandisa chubhu choto kupfuudza haidrojeni neyakasungwa kunze kwekusungwa kunoputika, matanho ekuchengetedza anofanirwa kutorwa. Usamira kumativi ose maviri echubhu yevira. Kana ukapfuura hydrogen, ndapota shandisa Stainless simbi machubhu. Nekuti simbi isina tsvina ine yakakura yekupisa conductivity kupfuura quartz, migumo yese yesimbi isina tsvina inoda kunyoroveswa nemvura, zvikasadaro tembiricha yeO-ring yakanyanya uye haigone kuvharwa.

4. Ndapota iva nechokwadi chekuisa ceramic plugs muchoto chevira paunenge uchipisa, kana zvisina kudaro tembiricha pamigumo miviri yechubhu yechoto ichave yakakwirira, uye maO-rings ari muflange haazokwanisi kumira kupisa kwepamusoro, zvichikonzera. kusasimba kwemhepo. Kuguma kunobatsira pakuumbwa kwenzvimbo yekushisa yakaenzana.

5. Paunenge uchipisa, tapota iva nechokwadi chekuisa plugs dzealumina muchoto chevira, kuisa 2 kune rumwe rutivi, 4 pamwe chete, kureba kwepakati pemativi maviri evhavha yechoto kunogona kuva 450mm (nokuti kureba kwekupisa. chikamu cheHTL1200 split tube furnace iri 400mm) Kana plug yechoto isina kuiswa, tembiricha kumagumo ese echoto chubhu yakakwira, uye O-ring iri muflange haigone kumira tembiricha yakakwira, izvo zvinoita kuti kusimba kwemhepo kuve kushomeka. . Kuisa plug yechoto pamativi ese echubhu yechoto kuchabatsira kugadzira tembiricha yakaenzana. munda.

6. Kudzivirirwa kwekushisa kwechubhu yequartz kune hukama nekuchena kwayo. Iyo yakakwirira kuchena, iyo yakakwirira yekudzivirira kwekushisa.
