Mashandisirwo egrafiti ine hutsanana hwakanyanya: Graphite powder. Nei graphite powder yakakurumbira? Musika wemuno we graphite heaters unotarisirwa kuva wakanaka. Nei graphite heaters iri kuwedzera kufarirwa nevanhu? Kutaura zvazviri, chikonzero chiri kuwedzera kufarirwa nevanhu hachisiyaniswi nezvakanakira zvayo. Iye zvino, ngatitarisei zvakanakira graphite heater pamwe chete!
1. Inobvisa zvachose oxidation uye decarburization pamusoro pebasa panguva yekupisa, uye inogona kuwana nzvimbo yakachena isina layer yakaora. Izvi zvakakosha zvikuru pakuvandudza mashandiro ekucheka kwezvishandiso zvinongokuya divi rimwe chete panguva yekukuya (senge twist drills apo layer decarburization pamusoro pe groove inoonekwa zvakananga kumucheto wekucheka mushure mekukuya).
2. Hazvikonzere kusvibiswa kwezvakatipoteredza uye hazvidi kuti marara matatu aya agadziriswe.
3. Ine michina yakawanda. Zvichibva pakuvandudzwa kwekuyera tembiricha uye kurongeka kwekudzora, kufamba kwezvishandiso, kugadzirisa kumanikidzwa kwemhepo, kugadzirisa simba, nezvimwewo zvinogona kurongwa uye kuiswa, uye kudzima nekudzikamisa zvinogona kuitwa nhanho nhanho.
4. Kushandiswa kwesimba kwakaderera zvakanyanya pane kwezvitofu zvekugezera zvine munyu. Kamuri yekupisa yemazuva ano ye graphite heater ine madziro ekudzivirira kupisa uye zvipingamupinyi zvakagadzirwa nezvinhu zvemhando yepamusoro zvekudzivirira kupisa, izvo zvinogona kusanganisa simba remagetsi rekudziyisa mukati mekamuri rekudziyisa, zvichiita kuti simba rive rakakosha pakuchengetedza simba.
5. Kururama kwekuyera nekutarisa tembiricha yechoto kwavandudzika zvikuru. Kukosha kwechiratidzo che thermocouple kunosvika ± tembiricha yechoto.1.5°c. Zvisinei, musiyano wekupisa pakati pezvikamu zvakasiyana zvezvishandiso zvakawanda muchoto wakakura. Kana kutenderera kwegasi risingawanzoitiki kukaitwa, musiyano wekupisa unogona kudzorwa mukati me ±5°c.
Kubvisa gasi ndicho chiitiko chekubuda kwemhepo zvishoma nezvishoma kwezvinhu mu graphite heater uye ndicho chinhu chakakosha pakushanda kwe graphite heater. Ma molecule layers anoumbwa nekuunganidzwa kwemagasi nemvura anogona kunamira pamusoro pechinhu chero chipi zvacho chakasimba. Nekuda kwekuderera zvishoma nezvishoma kwekumanikidzwa, aya ma molecule layers achabuda zvishoma nezvishoma nekuti simba renzvimbo idzi harisi pasi perinoburitswa ne graphite heater. Nitrogen, volatile solvents uye inert gases zvine mwero wekubvisa gasi nekukurumidza. Mafuta nemhepo inoramba ichinamira pamusoro uye haizopwanyi kusvika maawa akati wandei gare gare. Zvinhu zvine maburi, guruva nezvimwe zvinhu zvakasikwa zvinowedzera nzvimbo yepamusoro, saka zvinokwanisika kukonzera kubuda kwegasi kwakawanda. Mwaranzi netembiricha zvinopa simba rakakwana kuti ma molecule anonyudza abve pamusoro. Kana tembiricha ye fireplace yakwira, inogona kusunungura ma molecules akanamatira pamusoro patembiricha yakaderera. Saka, sezvo tembiricha ye fireplace ichikwira, chiitiko chekubvisa gasi chichawedzera zvishoma nezvishoma.
Maumbirwo, kudzora tembiricha, maitiro ekudziya uye mamiriro ari mukati mechoto che graphite heater zvese zvinokanganisa zvakananga kunaka kwechigadzirwa mushure mekugadzirwa kwe graphite heater. Muchoto chekupisa che forging, kukwidza tembiricha yesimbi kunogona kuderedza kuramba kwekunyunguduka, asi tembiricha yakakwira zvakanyanya inogona kukonzera oxidation yegorosi kana kupisa zvakanyanya, zvichikanganisa zvakanyanya kunaka kwechigadzirwa chiri mukati me graphite heater. Munguva yekurapa kupisa, kana simbi ikapiswa kusvika panzvimbo yakati pamusoro petembiricha yakakosha uye yozongoerekana yatonhodzwa nemushonga wekutonhodza, kuomarara nesimba resimbi kunogona kuwedzerwa. Kana simbi ikapiswa kusvika panzvimbo yakati pasi petembiricha yakakosha uye yozotonhodzwa zvishoma nezvishoma, zvinogona kuita kuti simbi irambe yakasimba.
Kuti pave nemidziyo yebasa ine nzvimbo dzakatsetseka uye saizi dzakarurama, kana kuderedza oxidation yesimbi nechinangwa chekudzivirira maforoma uye kuderedza machining allowances, maovheni akasiyana-siyana ekupisa ane low oxidation uye non-oxidation anogona kushandiswa. Muovheni yekupisa ine moto wakavhurika isina oxidation yakawanda kana isina oxidation, kupisa mafuta kusina kukwana kunogadzira gasi rinodzikisa. Kupisa workpiece iri mairi kunogona kuderedza mwero wekurasikirwa kwe oxidation kusvika pasi pe 0.6%. Graphite ine kuchena kwakanyanya inoreva upfu hwe graphite ine kabhoni inodarika 99.9%. Iyi graphite ine kuchena kwakanyanya ine kabhoni yakawanda ine conductivity yemagetsi yakanaka, marobhoti, resistance high-temperature, resistance wear, etc. Graphite ine kuchena kwakanyanya ine plasticity yakanaka uye inogona kugadziriswa kuita zvinhu zvakasiyana-siyana zvinofambisa, nezvimwewo.
Graphite ine pureity yakanyanya ine mashandisirwo akakosha mumunda wekugadzira maindasitiri. Inoshandiswa mumaindasitiri akadai semagetsi, mafuta, uye simbi. Munguva yekugadzira graphite ine pureity yakanyanya, huwandu hwetsvina hunofanira kudzorwa zvakanyanya kubva muzvinhu zvakagadziriswa, uye zvinhu zvisina kucheneswa zvine dota shoma zvinofanira kusarudzwa. Uyezve, kuedza kunofanirwa kuitwa kudzivirira kuwedzerwa kwetsvina zvakanyanya sezvinobvira panguva yekugadzira. Zvisinei, kuderedza tsvina kusvika padanho rinodiwa kunonyanya kuitika mukuita graphitization. Graphitization inoitika pakupisa kwakanyanya, uye ma oxide mazhinji ezvinhu zvisina kuchena anoora uye anonyangarika pakupisa kwakanyanya kwakadaro. Kana tembiricha yegraphitization yakakwira, tsvina yakawanda inoburitswa, uye kuchena kwezvigadzirwa zvegraphite zvine pureity yakakura kunobuda. Kushandiswa kwegraphite ine pureity yakanyanya kunoshandisa mukana wekufambisa kwayo zvakanaka kwemagetsi, kushanda kwayo kwekuzora, kuramba kupisa kwakanyanya, nezvimwewo.
Chikonzero nei graphite ine hutsanana hwakanyanya uye tsvina shoma zvese zvinoenderana nekugadzirwa kwakakwana uye michina. Hunhu hwetsvina huri pasi pe0.05%. Graphite yedu yecolloidal, nano-graphite, graphite ine hutsanana hwakanyanya, upfu hwegraphite hwakanyanya uye zvimwe zvigadzirwa zvegraphite powder zvinoshandiswa zvakanyanya mumaindasitiri emakemikari, peturu uye mafuta ekuzora. Upfu hwegraphite hwakanyanya hunoshandiswa mukugadzirisa nekugadzira zvinhu zvinodziya zvemagetsi, maforoma ekukanda, zvigadziko zvesimbi zvine hutsanana hwakanyanya hwekunyungudutsa, zvigadziko zvegraphite zvine hutsanana hwakanyanya, zvinhu zve semiconductor, nezvimwewo.
