Igishushanyoni ubwoko bushya bwo gufunga ibikoresho, kandi nubwoko bwingenzi bwibikoresho byo gufunga inganda zinganda.Ifite imbaraga zo kurwanya ruswa, irwanya ubushyuhe buke kandi buke, irwanya imishwarara ya electromagnetique, ibintu bito bito, kwikuramo amavuta, ubworoherane, hamwe n’ubushobozi buke bw’amazi na gaze.
Graphite gasketsIrashobora kuba hasi cyangwa gushyirwaho kashe kuva isahani ya grafite cyangwa icyuma (isahani yinyo, isahani iringaniye, inshundura) kugirango irusheho gushimangira ibyapa bya grafite ukurikije akazi kamwe.
1. Ibiranga igicapo cyoroshye cya grafite:
1. Grafite-isukuye cyane ifite ubudahangarwa bwiza bwa gaze namazi, nkisahani yoroheje ifite umubyimba wa 0.125mm, igipimo cya helium ni 2 * 10-1cm3 / s gusa.
2. Kurwanya ubushyuhe bwiza.Ubushyuhe bwa grafite ihindagurika muburyo butari hydrolytike ni -200 ~ 600℃, ariko biroroshye kuba okiside muburyo bwa hydrolytike.
3. Anisotropy: Gutwara ubushyuhe, gutwara amashanyarazi no kwagura coefficent ya grafite yoroheje ifite anisotropy igaragara.
4. Kurwanya UV gukomeye.
5. Kurwanya ruswa neza, imiti myiza ihindagurika kumashanyarazi rusange, esters, imyuka y'amazi, kugabanya itangazamakuru, nibindi.
Ariko, hari aho bigarukira muburyo bwa hydrolysis.
6. Ubucucike buke, imbaraga nyinshi, ubworoherane bwiza no kwihangana.
Ingano yo gushyira mu bikorwa igishushanyo mbonera
Ikoreshwa munganda zinganda, guhanahana ubushyuhe, gutwikira valve, kondenseri, kongera ingufu, imiyoboro isohoka, firigo, nibindi.
Uburyo bukoreshwa: amazi, amavuta, amavuta, aside, alkali, ibishishwa kama, ammonia, hydrogen, nibindi.
2. Ibyuma bitagira umwanda bikomeza gushimangira gasike
Graphite ikomeye-gasketi, bizwi kandi nka grafite ya gazi ya gazi, bikozwe mubindi bishimangira urupapuro rwerekana impapuro cyangwa hasi.Ibikoresho byo kumurongo birashobora kuba urupapuro rumwe nkuko bisabwa.Bitewe nimbaraga nyinshi zubukanishi bwibikoresho byoroshye bya grafitike, birakwiriye kuri gasketi ifite diameter ntoya, kandi gukomeza gushimangira gasketi ya grafite bizamura cyane imbaraga za mashini.Ibintu byiza cyane nko kurwanya ruswa ya chimique, kurwanya imishwarara ya electromagnetique, kurwanya ubushyuhe buke / buke, no kuramba.
Ibindi byongeweho kuri grafite ya gasike:
1. Ibyuma bya karubone bikomeza gushimangiraigishushanyo mbonera: iherezo ryurupapuro rworoshye rwa grafite rushyizwe hamwe nicyuma cya karubone (0.2mm), hanyuma hasi, ikomeza imbaraga za mashini.
2. 304 ibyuma bidafite ingese birushijeho gushimangira gasike ya grafite: flake ya grafite yoroheje ihujwe kumpande zombi za 304 ibyuma bitagira umuyonga, bifite imbaraga zo gukanika cyane.Irakwiriye kandi ubunini bunini nuburyo butandukanye, kandi biroroshye gutwara.Nibisanzwe bizwi cyane murwego rwo gusaba.Ubwinshi bwa gasketi.
3. 316 ibyuma bidafite ingese birashimangira gaze ya grafite: ifite imbaraga zo kurwanya ruswa hamwe nubushyuhe bwo hejuru, ariko igiciro nacyo kiri munsi yibindi bikoresho.
3. Ibyuma bya grafite bikozwe mu gaseke
Ibyuma-bishushanyije bikozwe mu bwoko bwa gasketi ni ubwoko bwibyuma-bidafite ingufu bya gasketi bikozwe mubitereko byicyuma na grafite.Zivanze kuva kuri V cyangwa V zifite imirongo yoroheje yicyuma hamwe nuwuzuza.Hamwe nimiyoboro myinshi yo gufunga no kwizirika ku mikorere, ntabwo ishobora kwibasirwa n inenge ya flange yakandagiye hejuru yikimenyetso, kandi ntabwo ari NaCl flange igaragara;biroroshye gusenya, kandi birashobora gukuraho igice ingaruka zumuvuduko, ihinduka ryubushyuhe hamwe no kunyeganyega kwa mashini;irashobora gukoreshwa mubushuhe buhebuje hamwe n'ubushuhe buke Irakomeza ibikorwa byiza byo gufunga mubihe bitandukanye bikabije mugihe cyo kuzenguruka nka, vacuum nyinshi, guhungabana no kunyeganyega.Icyuma cya grafite gikozwe mucyuma gikwiranye n'ubushyuhe, kandi byoroshyeigishushanyoumukandara ubereye ubushyuhe -196 ~ 650°C (ntabwo iri munsi ya 450°C muburyo bwa hydrolysis)
