Special graphite ndeyekuchena kwepamusoro, kusimba kwepamusoro uye kusimba kwepamusorographitezvinhu uye ine yakanakisa corrosion resistance, yakanyanya kugadzikana tembiricha uye yakakura magetsi conductivity. Yakagadzirwa neakasikwa kana yekugadzira graphite mushure mekupisa kwekushisa kwepamusoro kurapwa uye kudzvanywa kwepamusoro uye inowanzoshandiswa mumaindasitiri ekushandisa mukupisa kwakanyanya, kudzvanywa kwepamusoro uye nharaunda dzinoparadza.
Inogona kukamurwa mumhando dzakasiyana siyana kusanganisira isostaticgraphite blocks, mabhuroko egraphite akawedzera, akaumbwagraphite blocksuye vibratedgraphite blocks.

Graphitechinhu chakasarudzika chisiri chesimbi chinoumbwa nemaatomu ecarbon akarongwa mune hexagonal lattice chimiro. Icho chinhu chakapfava uye chine brittle chinowanzo shandiswa mune akasiyana maindasitiri ekushandisa nekuda kweayo akasiyana zvivakwa. Graphite inogona kuchengetedza simba rayo uye kugadzikana kunyangwe kune tembiricha inodarika 3600 ° C. Zvino regai ndizivise maitiro ekugadzira magirafu anokosha.
Isostatic graphite, yakagadzirwa nehutsanana hwepamusoro graphite nekutsikirira, chinhu chisingachinjiki chinoshandiswa mukugadzira imwe chete crystal furnaces, simbi inoramba ichikanda graphite crystallizers, uye graphite electrodes yemagetsi spark discharge machining. Pamusoro peaya maapplications makuru, anoshandiswa zvakanyanya muminda yakaoma alloys (vacuum furnace heaters, sintering plates, etc.), migodhi (kugadzira drill bit molds), indasitiri yemakemikari (heat exchangers, corrosion-resistant parts), metallurgy (crucibles), uye michina (mechanicha zvisimbiso).
Molding Technology
Nheyo ye isostatic yekutsikirira tekinoroji yakavakirwa pamutemo waPascal. Iyo inoshandura iyo unidirectional (kana bidirectional) kudzvanywa kwezvinhu kuita akawanda-directional (omnidirectional) compression. Munguva yekuita, iyo kabhoni particles inogara iri mune isina kurongeka, uye vhoriyamu density inofanana neiyo isotropic properties. Kunze kwezvo, haisi pasi pehurefu hwechigadzirwa, nokudaro kuita iyo isostatic graphite isina kana misiyano mishoma yekuita.
Zvinoenderana nekushisa uko kuumbwa uye kusimba kunoitika, isostatic yekutsikirira tekinoroji inogona kukamurwa kuita inotonhora isostatic kudzvanya, inodziya isostatic kudzvanya, uye inopisa isostatic kudzvanya. Isostatic pressing products ine high density, kazhinji 5% kusvika 15% yakakwirira pane iyo yeunidirectional kana bidirectional mold kudzvanya zvigadzirwa. Iyo hukama density ye isostatic kudzvanya zvigadzirwa inogona kusvika 99.8% kusvika 99.09%.
Molded graphite ine maitiro akatanhamara musimba remuchina, abrasion resistance, density, kuomarara uye magetsi conductivity uye kuita uku kunogona kuvandudzwa nekuisa resin kana simbi.
Molded graphite inoratidzira yakanaka magetsi conductivity, yakakwirira tembiricha kuramba, ngura kuramba, kuchena kwakanyanya, self-lubrication, thermal shock resistance uye nyore kuita machining, uye inoshandiswa zvakanyanya muminda yekuramba ichikanda, hard alloy uye electronic die sintering, electric spark, mechanical seal, nezvimwewo.

Iyo yekuumba nzira inowanzo shandiswa kugadzira diki-saizi inotonhora-yakadzvanywa graphite kana zvigadzirwa zvakarongeka. Nheyo yacho ndeyekuzadza imwe huwandu hwenamira muforoma yechimiro chinodiwa uye saizi, wobva waisa kumanikidza kubva kumusoro kana pasi. Dzimwe nguva, shandisa kudzvanywa kubva kumativi ese maviri kudzvanya paste kuita chimiro muforoma. Iyo yakadzvanywa semi-yakapera chigadzirwa chinozogadziriswa, chatonhodzwa, choongororwa, uye chakaiswa.
Kune ese akamira uye akachinjika ekuumba michina. Molding nzira kazhinji inogona kungotsikirira chigadzirwa chimwe panguva, saka ine yakaderera kugadzirwa kwekuita. Nekudaro, inogona kuburitsa yakakwirira-chaiyo zvigadzirwa zvisingakwanisi kugadzirwa nemamwe matekinoroji. Uyezve, kugona kwekugadzira kunogona kuvandudzwa kuburikidza nekutsikirira panguva imwe chete yeakawanda mold uye otomatiki mitsara yekugadzira.
Extruded graphite inoumbwa nekusanganisa high purity graphite particles nebhainda uye wozoaburitsa mune extruder. Kana ichienzaniswa neisostatic graphite, iyo extruded graphite ine coarser saizi yezviyo uye yakaderera simba, asi ine yakakwirira yekupisa uye magetsi conductivity.
Parizvino, yakawanda kabhoni uye graphite zvigadzirwa zvinogadzirwa ne extrusion nzira. Iwo anonyanya kushandiswa seanodziya zvinhu uye thermal conductive zvikamu mune yakakwirira-tembiricha kupisa kurapwa maitiro. Uye zvakare, ma graphite zvidhinha anogona zvakare kushandiswa se electrode kuita ikozvino kuendesa mune electrolysis maitiro. Naizvozvo, anoshandiswa zvakanyanya semakanika zvisimbiso, thermal conductive zvinhu uye electrode zvinhu munzvimbo dzakanyanyisa dzakadai senge tembiricha yakanyanya, kudzvanywa, uye kumhanya kwakanyanya.

Iyo extrusion nzira ndeyekurodha paste muhumburumbira wepaste yemuchina uye kuiburitsa. Muchina wekudhinda wakashongedzerwa neinotsiviwa extrusion mhete (inogona kutsiviwa kuti ichinje muchinjiko-chikamu chimiro uye saizi yechigadzirwa) pamberi payo, uye inofambiswa baffle inopiwa pamberi pechindori cheextrusion. Iyo huru plunger yemuchina iri kuseri kwe silinda yekunamira.
Usati waisa dzvinyiriro, isa baffle pamberi pemhete yeextrusion, uye isa kumanikidza kubva kune yakapesana nekumanikidza namira. Kana iyo baffle ichibviswa uye kudzvanywa kunoenderera mberi kushandiswa, iyo paste inoburitswa kubva kune extrusion mhete. Cheka tambo yakawedzera muhurefu hwaunoda, tonhorera uye uongorore usati waisa. Iyo extrusion nzira ndeye semi-inopfuurira yekugadzira maitiro, izvo zvinoreva kuti mushure mekunge imwe huwandu hwenamira hwawedzerwa, akati wandei (graphite blocks, graphite zvinhu) zvigadzirwa zvinogona kuramba zvichiwedzera.
Parizvino, yakawanda kabhoni uye graphite zvigadzirwa zvinogadzirwa ne extrusion nzira.
Vibrated graphite ine chimiro chakafanana nekukura kwezviyo zvepakati. Kunze kwezvo, inove yakakurumbira nekuda kweiyo yakaderera madota emukati, yakawedzera simba remuchina, uye yakanaka magetsi uye yekupisa kugadzikana, uye inoshandiswa zvakanyanya kugadzirisa mahombe-akawanda ebasa. Inogona zvakare kusimbiswa zvakare mushure mekuiswa resin kana anti-oxidation kurapwa.
Inoshandiswa zvakanyanya sechinhu chekudziya & chekudzivirira mukugadzirwa kwepolysilicon uye monocrystalline silicon furnaces muindasitiri yephotovoltaic. Inoshandiswawo zvakanyanya mukugadzira mahodhi ekudziya, zvinopisa zvinopisa, kunyunguduka uye kukanda macrucibles, kuvaka n node dzinoshandiswa mumagetsi emagetsi maitiro, uye kugadzira macrucibles ekunyungudusa uye alloying.
Molding Technology
Nheyo yekugadzira vibrated graphite ndeyekuzadza mold nemusanganiswa-wakafanana musanganiswa, wozoisa simbi inorema pamusoro payo. Muchinhanho chinotevera, zvinhu zvakabatanidzwa nekudedera mold. Kana ichienzaniswa neiyo extruded graphite, iyo graphite inoumbwa nekuzunguza ine yakakwira isotropy. graphite zvigadzirwa zvinogadzirwa ne extrusion nzira.
