Iko kushandiswa kwepamusoro-kuchena graphite: Graphite poda. Sei graphite powder yakakurumbira zvakadaro? Musika wepamusha wema graphite heaters unotarisirwa kunge uchivimbisa. Sei ma graphite heaters ari kuwedzera mukurumbira pakati pevanhu? Muchokwadi, chikonzero nei iri kuwedzera kuve yakakurumbira pakati pevanhu haina kupatsanurwa kubva kune zvayakanakira. Zvino, ngatitarisei zvakanakira iyo graphite heater pamwechete!
1. Inobvisa zvachose oxidation uye decarburization pamusoro pebasa rekushanda panguva yekupisa, uye inogona kuwana nzvimbo yakachena pasina chidimbu chakaora. Izvi zvakakosha zvikuru pakuvandudzwa kwekuita kwekucheka kwezvishandiso izvo zvinongogaya divi rimwe chete panguva yekukuya (senge twist drills apo decarburization layer pa groove surface inooneswa kumucheto kwekucheka mushure mekugaya).
2. Izvo zvinokonzera kusasvibiswa kune zvakatipoteredza uye hazvidi kurapwa kwemarara matatu.
3. Iine dhigirii yepamusoro ye mechatronics. Zvichienderana nekuvandudzwa kweyero yekushisa uye kurongeka kwekutonga, kufamba kwezvishandiso, kugadziriswa kwemhepo, kugadzirisa simba, nezvimwewo zvinogona kunge zvakagadzirirwa uye zvakagadzirirwa, uye kudzima uye kupisa kunogona kuitwa nhanho nhanho.
4. Kushandiswa kwesimba kunonyanya kuderera kudarika kuvira kwemunyu. Iyo yemazuva ano yepamusoro girafu heater heater yekudziya kamuri yakashongedzerwa nemadziro ekudzivirira uye zvipingamupinyi zvakagadzirwa zvemhando yepamusoro zvidzitiro zvekudzivirira, izvo zvinogona kutarisisa zvakanyanya magetsi ekupisa mukati mekamuri yekudziya, kuwana inoshamisa-yekuchengetedza simba mhedzisiro.
5. Kururama kwekuyera kwekushisa kwechoto uye kutarisa kwakagadziridzwa zvakanyanya. Iko kukosha kwechiratidzo che thermocouple inosvika ± tembiricha yevira1.5°c. Nekudaro, mutsauko wekushisa pakati pezvikamu zvakasiyana zvenhamba huru yezvishandiso muchoto yakakura. Kana kutenderera kwekumanikidzwa kwegasi risingawanzo gamuchirwa, musiyano wetembiricha unogona kudzorwa mukati me ± 5 ° c.
Degassing chiitiko chekunonoka kubuda kwezvinhu mu graphite heater uye ndiyo inonyanya kukosha mukuita kweiyo girafu heater. Molecular layers inoumbwa nekuunganidzwa kwemagasi uye zvinwiwa zvinogona kunamatira kumusoro kwechero chinhu chakasimba. Nekuda kwekudzikira zvishoma nezvishoma mukumanikidza, aya ma molecular layers anozobuda zvishoma nezvishoma nekuti simba renzvimbo idzi ishoma pane rinoburitswa ne graphite heater. Nitrogen, volatile solvents uye magasi anert ane kukurumidza kubvisa gasi. Mafuta nemhute yemvura zvicharamba zvakanamatira kumusoro uye hazvizonyunguduke kusvika maawa akati wandei gare gare. Porous zvinhu, guruva particles uye zvimwe zvinhu zvakasikwa zvichawedzera pamusoro penzvimbo, saka zvinokwanisika kukonzera kuwedzera degassing kuitika. Radiation uye tembiricha zvinopa simba rakakwana kuita kuti mamorekuru anonwisa abude kubva pamusoro. Kana tembiricha yechoto ichikwira, inogona kuburitsa mamorekuru akaomerera kumusoro pakudziya kwakaderera. Nokudaro, sezvo kutonhora kwechoto kuchikwira, chiitiko che degassing chichawedzera zvishoma nezvishoma.
Chimiro, kudzora tembiricha, kupisa maitiro uye mhepo mukati mechoto che graphite heater zvese zvinokanganisa kunaka kwechigadzirwa mushure mekugadzirwa kweiyo girafu heater. Muchoto chekugadzira kupisa, kusimudza tembiricha yesimbi kunogona kuderedza kunyungudika, asi tembiricha yakanyanyisa inogona kukonzera oxidation yezviyo kana kupisa zvakanyanya, zvichikanganisa zvakanyanya kunaka kwechigadzirwa mukati meiyo graphite heater. Munguva yekupisa kwekupisa, kana simbi inopisa kune imwe nzvimbo pamusoro pekushisa kwakakosha uye kamwe kamwe yakatonhodzwa nemushandi wekutonhora, kuoma uye kusimba kwesimbi kunogona kuvandudzwa. Kana simbi yacho ichipisa kune imwe nzvimbo iri pasi pekushisa kwakakosha uye yobva yatonhodzwa zvishoma nezvishoma, inogona kuita kuti simbi iwedzere kugadzikana.
Kuti uwane maworkpieces ane nzvimbo yakatsetseka uye zviyero zvakaringana, kana kudzikisa simbi oxidation nechinangwa chekudzivirira mold uye kuderedza machining mvumo, dzakasiyana-siyana yakaderera-oxidation uye isina-oxidation yekupisa mavira inogona kugamuchirwa. Muchoto chemoto chakavhurika chine oxidation shoma kana isina, kupisa kusina kukwana kwemafuta kunogadzira kuderedza gasi. Kupisa iyo workpiece mairi kunogona kuderedza oxidation kupisa kurasikirwa mwero kusvika pasi pe0.6%. High-purity graphite inoreva graphite powder ine carbon content inopfuura 99.9%. Iyi high-purity graphite ine high carbon content ine yakanakisa magetsi conductivity, lubricating properties, high-temperature resistance, wear resistance, etc. High-purity graphite ine plasticity yakanaka uye inogona kugadziriswa mune zvakasiyana-siyana conductive zvinhu, nezvimwewo.
Yakakwirira-kuchena graphite ine yakakosha mashandisirwo mumunda wekugadzira maindasitiri. Inoshandiswa mumaindasitiri akadai semagetsi conductivity, lubrication, uye metallurgy. Panguva yekugadzirwa kwepamusoro-kuchena graphite, zvinyorwa zvezvisina kuchena zvinofanira kunyatsodzorwa kubva kune zvakasvibirira, uye zvinhu zvakasvibiswa zvine madota mashoma zvinofanira kusarudzwa. Uyezve, kuedza kunofanirwa kuitwa kudzivirira kuwedzerwa kwetsvina zvakanyanya sezvinobvira panguva yekugadzira. Nekudaro, kudzikisa kusvibiswa kusvika padanho rinodiwa zvinonyanya kuitika mukuita graphitization. Graphitization inoitika pakupisa kwakanyanya, uye maokisi akawanda ezvisina kuchena anoora nekubuda mumhepo pakupisa kwakanyanya kudaro. Iyo yakakwirira tembiricha ye graphitization, iyo yakawanda tsvina inobuda, uye iyo yakakwirira kuchena kwepamusoro-kuchena graphite zvigadzirwa zvinogadzirwa. Iko kushandiswa kwepamusoro-kuchena graphite kunotora mukana weiyo yakanakisa magetsi conductivity, lubricating performance, yakakwirira-tembiricha kuramba, nezvimwe.
Chikonzero nei yakakwirira-kuchena graphite ine yakakwirira kuchena uye mashoma tsvina zvese zvinoenderana neyakakwana yekugadzira maitiro uye michina. Izvo zvisina kuchena zviri pasi pe0.05%. Yedu colloidal graphite, nano-graphite, yakakwirira-kuchena graphite, ultrafine graphite poda uye zvimwe graphite poda zvigadzirwa zvinoshandiswa zvakanyanya mumakemikari, petroleum uye lubrication maindasitiri. Yakakwirira-kuchena graphite poda inoiswa mukugadzirisa nekugadzira magetsi ekudziya zvinhu, zvimiro zvekukanda molds, yakakwirira-kuchena simbi crucibles yekunyungudutsa, yakakwirira-kuchena graphite crucibles, semiconductor zvinhu, nezvimwe.
