Mumaindasitiri emazuva ano, kuvimbika, kushanda zvakanaka uye kudzora kusvibiswa kwezvinhu zvakakosha zvikuru, uye tekinoroji yekuisa michina ine basa guru. Kubva kumafekitori ekugadzira makemikari kusvika kumafekitori ekugadzira zvinhu zve semiconductor, nguva yakajairika yekushanda kwemidziyo inowanzoenderana nechikamu chidiki asi chakakosha - mashandiro ekuisa michina.
Sezvo maitiro emaindasitiri achiramba achifambira mberi uye zvinodiwa zvichikwira, nzira dzechinyakare dzekuvhara (dzakadai sekuisa zvisimbiso) dzakatsiviwa zvishoma nezvishoma nezvisimbiso zvemakanika. Simba rinosimudzira shanduko iyi rinobva pane zvinotevera:
● Kumanikidzwa kwakanyanya kwebasa
● Kudzora zviri nani kubuda kwemvura
● Nguva refu yebasa
● Kuenderana nemakemikari anoparadza
● Kushandisa simba zvakanyanya
Munguva yekugadzirwa uku, sainzi yezvinhu yakaita basa guru. Pakati pezvinhu zvese zvinovhara, zvinhu zvakagadzirwa nekabhoni - kunyanya kabhoni graphite - zvave chinhu chikuru chinotungamira masisitimu ekuvhara anoshanda zvakanyanya mumaindasitiri emakemikari, petrochemical uye semiconductor.
Chii chinonzi carbon-graphite mechanical seal?
Zvisimbiso zvekabhoni graphite mechanical zvikamu zvekuvhara zvakagadzirwa nemazvo, zvinowanzoshandiswa mumidziyo inotenderera yakaita semapombi, macompressor, uye mamixers. Zvinosanganisira mhete dzekuvhara dzakagadzika kana dzinotenderera dzakagadzirwa nezvinhu zvekabhoni graphite.
Mhete idzi dzekuvhara dzinoshandiswa pamwe chete nezvinhu zvakasimba zviviri (senge silicon carbide kana ceramics), zvichiita kuti pave nechinhu chinodzorwa chekuvhara chinodzivirira kubuda kwemvura kana gasi uku chichibvumira kufamba kwese kwese.
Basa guru re carbon graphite seals nderekuchengetedza jira rakatetepa remafuta pakati penzvimbo mbiri idzi, nokudaro zvichiita kuti:
● Kukweshana kushoma
● Kupfeka zvinodzorwa
● Kuchengetedza kushanda kwakasimba kwechisimbiso kwenguva yakareba yekushanda
Sei carbon graphite iri chinhu chinodiwa pakuisa zvisimbiso zvemakanika
Graphite yekabhoni inoshandiswa zvakanyanya mumichina yekuvhara michina nekuda kwehunhu hwayo hwakasiyana hwemuviri uye hwetribological. Kusiyana nesimbi kana zvinhu zveceramic, graphite yekabhoni ine mafuta emuzvarirwo uye inogona kuchengetedza kushanda kwakasimba mumamiriro ekushanda akaoma uye akanyorova.
Hunhu hukuru hwemuviri:
✔ Kukweshana kwakaderera: 0.05 ~0.15
✔ Chinhu chinozvizora chega: Chimiro chegirazi regirafu rakaiswa muzvikamu
✔ Kugadzikana kwekupisa: Kusvika 200–450°C (giredhi remazuva ose), yakakwira kune magiredhi akakosha
✔ Kusagona kushandisa makemikari: Kusagona kushandisa acid, alkalis uye organic solvents zvakanaka kwazvo
✔ Simba rekudzvanya: Kazhinji 80–200 MPa (zvichienderana nerudzi rwekudzvanya)
✔ Kuwanda: 1.6 ~2.1 g/cm³
✔ Muganho wePV (kumanikidzwa × kumhanya): 10–200 bar·m/s (zvichienderana negiredhi)
Hunhu uhwu hunoita kuti girafiti yekabhoni ive yakakodzera zvakanyanya munzvimbo dzakaoma dzekuvhara, uko zvinhu zvechinyakare zvingatadza kushanda nekuda kwekusakara, ngura kana kuora kwekupisa.
Hunhu hwegirafiti hunozvizora hwakakosha zvikuru. Maumbirwo ayo emaatomu ane zvidimbu zvinoita kuti zvive nyore kuchekerera zvidimbu, nokudaro zvichideredza zvakanyanya kukweshana nekupfekwa panguva yekushanda.
Masisitimu akajairika ezvisimbiso zvekabhoni graphite
Zvisimbiso zvekabhoni graphite hazvisi chinhu chimwe chete, asi zvinhu zvakasiyana-siyana zvakagadzirwa neunyanzvi. Sisitimu inonyanya kushandiswa inosanganisira:
Graphite yekabhoni yakanyudzwa neresin:Yakakodzera kushandiswa mumaindasitiri. Ine hunhu hwakanaka hwekuzvizora yoga uye inoita kuti ishandise mari zvakanaka.
Graphite yekabhoni ine antimony:Ine simba guru rekupisa uye ine simba remakanika, uye yakakodzera mapombi anomhanya zvakanyanya kana ane mutoro wakawanda.
Kabhoni graphite yakaiswa musimbi (mhangura, sirivha, nezvimwewo):Yakagadzirirwa mamiriro akaipisisa apo kupisa kwakanyanya kunopera uye kugadzikana kwechimiro kunodiwa.
Sisitimu yega yega yakagadziriswa kuti ishande zvakanaka (senge tembiricha, kumanikidzwa, makemikari anoenderana uye kumhanya kwekutenderera).
Mashandisirwo muindasitiri yesemiconductor
Kunyangwe zvisimbiso zvemakanika zvisiri chikamu chemichina yekugadzirisa wafer zvakananga, zvine basa rakakosha mukugadzirwa kwemidziyo yesemiconductor.
Zvisimbiso zvekabhoni graphite zvinoshandiswa zvakanyanya mu:
● Pombi yemvura isina kusimba
● Sisitimu yekutumira mishonga (HF, HCl, H₂SO₄, nezvimwewo)
● Sisitimu yekuendesa slurry yeCMP
● Sisitimu yemvura yakachena kwazvo (UPW)
● Midziyo yekugadzira zvinhu yakanyorova
Mumasystem aya, kuvimbika kwekuvharwa kwesimbi kunokanganisa zvakananga nguva yakajairika yekushanda kwefekitori yewafer uye kudzora kusvibiswa. Kunyangwe kudonha kudiki kana kugadzirwa kwezvidimbu zvinogona kutungamira mukukanganiswa kukuru kwemaitiro kana kurasikirwa negoho.
Saka, zvisimbiso zvekabhoni-graphite zvinoonekwa sechinhu chakakosha mukugadzirwa kwezvinhu zve semiconductor, sezvo zvichikosha pakuona kuti zvinhu zvakavimbika.
Zvisimbiso zveCarbon Graphite Mechanical uye Semiconductor Graphite
Kunyangwe zvese izvi zvinhu zvakavakirwa pacarbon, pfungwa dzekugadzira kwavo uye zvinodiwa pakushanda kwazvo zvakasiyana zvachose.
Carbon graphite mechanical chisimbiso:
● Inotarisa patribology (kukweshana, kupfeka, kukwiza mafuta)
● Yakagadzirirwa kufamba kwakasimba uye kuvharwa kwenzvimbo
● Zvinodiwa pakuchena zvine mwero zvinosangana nazvo
● Yakagadzirirwa zvakanyanya kuchengetedzwa kwemakemikari nemidziyo
Zvikamu zve graphite zve semiconductor:
● Inotarisa pakuchena kwakanyanya uye kudzora zvidimbu
● Inoshandiswa mumakamuri ekupisa kwakanyanya (CVD, MOCVD, EPI)
● Inoda SiC/PyC coating kana graphite yakachena kwazvo
● Yakagadzirirwa kugadzikana kwemunda wekupisa pane kudzora kukweshana
Muchidimbu, girafiti yechisimbiso chemuchina yakagadzirirwa kufamba nekuvhara, nepo girafiti yesemiconductor yakagadzirirwa kugadzikana kwekupisa uye kugadzikana kwemaitiro.
Mhinduro yeVet Energy yeCarbon Graphite Mechanical Seal
Ningbo VET Energy Technology Co., Ltd inosanganisa hunyanzvi hwepamusoro hwekugadzira zvinhu zvekabhoni nehunyanzvi hwekugadzirisa zvinhu nemazvo kuti ipe mhinduro dzechisimbiso chekabhoni graphite mechanical dzinoshanda zvakanaka pakushandiswa kwemaindasitiri epasi rose.
Zvigadzirwa zvedu zvinosanganisira:
