Gusobanukirwa Itandukaniro riri hagati yibumba ryibumba ryibumba na Graphite Silicon Carbide Crucibles

Iyo ukora ubushakashatsi bwo mu rwego rwo hejuru cyangwa ubushakashatsi bukoreshwa mu nganda, guhitamo ibikoresho byingenzi bigira uruhare runini mu gutuma intsinzi n'umutekano bigenda neza. Ubwoko bubiri bukoreshwa muburyo bwo kubambwa niibumba rya grafitenagrafite silicon karbide yabambwe. Gusobanukirwa ibiyigize, ubushyuhe bwo kwangara, kutagira imiti, hamwe nubushyuhe bwumuriro ningirakamaro muguhitamo neza mugihe uhisemo ibikenewe muri laboratoire cyangwa inganda zikenewe.

Ibikoresho:
Ibumba ryibumba ryibumba rigizwe ahanini na grafite, ibumba nubunini bwamavuta, kandi bizwiho kutagira imiti. Ku rundi ruhande, grafite ya silicon karbide ikomeye ikozwe mu ifu ya karubide ya silicon na okiside zimwe na zimwe zidasanzwe, kandi ifite ibiranga ubushyuhe bwo hejuru, guhangana n’ubushyuhe bukabije bw’ubushyuhe, hamwe n’ubushakashatsi bukabije bw’imiti.

Ubushyuhe bwo kurwanya umuriro:
Ubushyuhe bwo kugabanuka bwibumba ryibumba rya grafite mubusanzwe bigera kuri 1200 ° C, mugihe grafitike ya silicon karbide ishobora kwihanganira ubushyuhe buri hejuru ya 1500 ° C. Ibi bituma grafite silicon carbide ibamba cyane ikenewe mubisabwa bisaba ubushyuhe bwinshi mubushakashatsi bwimiti nibikorwa byinganda.

Imiti yimiti:
Ubwoko bwombi bwibibumbano bwerekana urugero rwubusembwa bwimiti, bugakomeza guhagarara neza muri aside nyinshi, alkali, n ibisubizo byumunyu kandi birwanya ruswa. Nyamara, ibumba ryibumba ryibumba rya grafite ryoroshe kwinjiza ibintu byanduye hamwe numwanda ugereranije na grafite silicon karbide yabambwe.

Amashanyarazi:
Graphite ifite ubushyuhe bwinshi kandi irashobora gukwirakwiza ubushyuhe vuba. Nyamara, bitewe nuburyo bubi bwibumba rya grafite ibumba, ibibara byirabura bikunze kugaragara hejuru yacyo kandi bisaba koza kenshi. Ibinyuranyo, grafite silicon karbide yabambwe ifite ubushyuhe buke bwumuriro kandi ntizisiga irangi hejuru. Byongeye kandi, gukomera kwabo birinda kwambara no guhindura ibintu.

Hitamo iburyo bukwiye:
Mugihe uhisemo laboratoire yimiti ikomeye, ibisabwa byihariye bigomba kwitabwaho. Ibumba ryibumba ryibumba rikwiranye nubushakashatsi rusange bwa chimie, mugihe grafite silicon karbide yabibwe nibyiza kubushakashatsi busaba ubushyuhe bwinshi nibisabwa cyane. Ni ngombwa gukurikiza byimazeyo amabwiriza yo gukoresha kugirango wirinde kunanirwa kugeragezwa kubera imikorere idakwiye.

Muncamake, gusobanukirwa gutandukanya ibumba ryibumba ryibumba na grafite silicon karbide ingirakamaro ni ngombwa muguhitamo igikenewe cyane muri laboratoire cyangwa gukoresha inganda. Urebye ibintu nkubushyuhe bukabije, ubudahangarwa bwimiti nubushyuhe bwumuriro, abashakashatsi ninzobere mu nganda barashobora gufata ibyemezo byuzuye kugirango bigerweho neza numutekano wubushakashatsi nibikorwa.
