Yini impahla engcono kakhulu yokubaleka?

Esikhathini se-metallurgy, chemistry, kanye nesayensi yezinto ezibonakalayo, ukukhethwa kwelungelo-cashileIzinto ezibonakalayo zibalulekile ekunqumeni impumelelo yezinqubo ezahlukahlukene, ezisukela ku-high-metal metal aroying kuya ekuhlolweni kwama-ceramics athuthukile nezibuko. Kunezinto ezimbalwa ezisebenzayo ezitholakalayo, ngayinye enesethi yayo eyingqayizivele yezakhiwo nezinzuzo. Ake sihlole izinto ezinhle kakhulu ze-CRICIbles ngemininingwane enkulu:

 

I-Quartz Earcribles

 I-Quartz errucles, evame ukwenziwa kusuka ku-silica ebuhlungu obukhulu, badume ngezimfanelo zabo ezihlukile. Badlula ekumelaneni namazinga okushisa aphezulu, okumele kube nemiphumela elonakalisayo yama-acid kanye nezisekelo, futhi kugcina ukuqina ngaphansi kwezimo ezingekho emthethweni. Lezi zinwele zathola i-niche yazo ekuncibilikiseni izinsimbi zokuhlanza okuphezulu njenge-silicon, i-aluminium nensimbi. Ngaphezu kwalokho, ukuhanjiswa kwabo okuphezulu okuphezulu kuthuthukisa ukusebenza kahle. Kodwa-ke, ikhwalithi yeprimiyamu ye-quartz iza ngephuzu lentengo eliphakeme.

 

Ama-Curamic ama-cramic

Ama-Curamic ama-Curamic afaka izigaba ezimbili ezinkulu: i-aluminium oxide ceramics ne-zirconium oxide ceramics. Lezi zinwele zinikeza ukumelana nokushisa okuhle kakhulu kanye nokuqina kwamakhemikhali, kubenza bakhethe ukuncibilika imfucuza eminingi yezinto zokwakha, kufaka phakathi izinsimbi, ingilazi, ceramics, nokuningi. Noma kunjalo, ukumelana kwabo nokushisa kwabo kuphansi kunalokho kwama-quartz ama-ruckible, okubenza balungele izinto ezinamaphoyinti ancibilikayo ngaphansi kuka-1700 ° C.

 

Ama-graphite ama-brucIbles

Ama-graphite ama-brucibles angama-WorkHorses ashisetwa okuphezulu, okucindezelayo kwengcindezi ephezulu, evame ukukhonza njengamathuluzi asemqoka ocwaningweni lwamakhemikhali. Lezi zinzulu zitholakala ngamafomu amabili aphansi: i-graphite yemvelo kanye ne-graphite yokwenziwa. Ama-graphite wemvelo ama-graphite aqhakambisa ukuzinza okuphakeme okuphezulu nokuqina kokugqwala, elungele izinhlelo ezahlukahlukene zokushisa okuphezulu. Ngakolunye uhlangothi, ama-graphite brickible zokwenziwa abiza kakhulu kepha kungenzeka anciphise ukuqina nokuqina kokugqwala.

 

I-Metal Crucibles

I-Metal Crucibles yakhiwa ngezinto zokwakha njengensimbi engenasici, i-molybderum, iplatinamu, nokuningi. Bayizinketho zokuzikhethela lapho besebenzelana nezinto zokwakha ngamaphoyinti aphezulu agqamile noma lapho ubhekene nezimo ezinamandla noma ze-alkali. I-Metal Crucibles ibonisa ukumelana okunamandla kokugqwala futhi ilondoloze ukuqina okumangalisayo okushisayo. Noma kunjalo, ukusetshenziswa kwazo kuhlotshaniswa nezindleko eziphakeme uma kuqhathaniswa nezinye izinto ezisebenzayo.

 

Sumzemari

TUkhetho lwezinto ezibalulekile kufanele luqhutshwe yizinto ezithile ezicutshungulwe kanye nezimo ezikhona ezincibilikayo. Uhlobo ngalunye lwe-Earciable lunikeza izinzuzo nemikhawulo yalo oluhlukile, kanye nokukhetha okulungile kubalulekile ukuze kufinyelelwe imiphumela ephumelelayo nekhwalithi ephezulu emikhakheni yeMetallurgy, Chemistry, kanye neSayensi Yezinto Ezibonakalayo.
