Ụzọ Nkwadebe nke Graphite Silicon Carbide Crucible nke dị elu maka mgbaze ọla.

Usoro nkwadebe nke ike dị elugraphite silicon carbide cruciblen'ihi na metal agbaze na-agụnye ndị a nzọụkwụ: 1) raw material nkwadebe; 2) isi agwakọta; 3) ihicha ihe; 4) ihichapu na nyocha; 5) nkwadebe ihe nke abụọ; 6) ngwakọta nke abụọ; 7) ịpị na ịkpụzi; 8) ịcha na trimming; 9) ihicha; 10) glazing; 11) ịgba égbè mbụ; 12) ime ime; 13) igba egbe nke abụọ; 14) mkpuchi; 15) emechara ngwaahịa. The crucible emepụtara site na iji usoro ọhụrụ a na usoro mmepụta nwere ike na-eguzogide okpomọkụ dị elu na nguzogide corrosion. Ogologo ndụ ndụ nke crucible ruru ọnwa 7-8, na-enwe ụdị ime ụlọ na-enweghị ntụpọ na enweghị ntụpọ, ike dị elu, mgbidi dị nro, na ezigbo ọkụ ọkụ. Na mgbakwunye, oyi akwa glaze na mkpuchi dị n'elu, yana ọtụtụ usoro ihicha na ịgba egbe, na-emeziwanye nguzogide corrosion nke ngwaahịa ahụ ma belata oriri ume site na ihe dịka 30%, yana nnukwu ogo vitrification.

Usoro a na-agụnye akụkụ nke nkedo igwe anaghị agba nchara, ọkachasị usoro nkwadebe nke silicon carbide crucible graphite siri ike maka mgbaze ọla.

[Technology Background] A na-ejikarị crocibles silicon carbide graphite pụrụ iche na nkedo ígwè na-arụ ọrụ nke na-abụghị nke ígwè, yana mgbake na nchacha ọla dị oké ọnụ ahịa, na mmepụta nke ngwaahịa dị elu na okpomọkụ na corrosion na-eguzogide ihe achọrọ maka plastik. ceramik, iko, simenti, rọba, na mmepụta ọgwụ, yana arịa na-eguzogide corrosion achọrọ na ụlọ ọrụ petrochemical.

Ụdị graphite pụrụ iche nke silicon carbide crucible formulations na mmepụta usoro na-emepụta ngwaahịa na nkezi ndụ nke ụbọchị 55, nke dị mkpụmkpụ. Ọnụ ego eji na mmepụta ihe na-aga n'ihu na-abawanye, ọnụ ọgụgụ mkpofu na-emepụta dịkwa elu. Ya mere, nyocha ụdị ọhụrụ pụrụ iche nke silicon carbide crucible graphite na usoro mmepụta ya bụ nsogbu ngwa ngwa iji dozie ya, ebe ọ bụ na crucibles ndị a nwere ngwa dị ịrịba ama na mpaghara kemịkalụ ụlọ ọrụ dị iche iche.

[0004] Iji dozie nsogbu ndị a dị n'elu, a na-enye usoro maka ịkwadebe ihe mkpuchi silicon carbide graphite dị ike maka mgbaze ígwè. Ngwaahịa ndị a kwadebere dị ka usoro a si dị na-eguzogide okpomọkụ dị elu na corrosion, na-arụ ọrụ ogologo oge, na-enwetakwa nchekwa ike, mbelata ikuku, nchebe gburugburu ebe obibi, na ọnụ ọgụgụ dị elu nke mkpofu n'oge mmepụta, na-eme ka mgbasawanye na iji ihe onwunwe eme ihe.

Usoro nkwadebe nke silicon carbide crucibles graphite dị ike maka mgbaze ọla gụnyere usoro ndị a:

1. Nkwadebe ihe eji eme ihe: Silicon carbide, graphite, ụrọ na silicon ọla na-etinye n'ime hoppers nke ha site na kreenu, yana mmemme PLC na-achịkwa mwepu na ịtụ ihe ọ bụla dịka nha achọrọ. valvụ pneumatic na-achịkwa mgbapụta ahụ, ma ọ dịkarịa ala abụọ ka edobere sensọ na-atụ n'ala ala nke ihe ọ bụla. Mgbe ị tụchara, a na-etinye ihe ndị ahụ n'ime igwe na-agwakọta site na ụgbọ ala na-ebugharị akpaka. Ihe mgbakwunye mbụ nke silicon carbide bụ 50% nke mkpokọta ya.
2. Ngwakọta nke abụọ: Mgbe agwakọtara akụrụngwa n'ime igwe agwakọta, a na-atụba ha n'ime ebe nchekwa ihe, a na-ebulikwa ihe ndị dị na ebe nchekwa ihe na-ebuli ya na igwe mbuli ịwụ maka ịgwakọta nke abụọ. A na-edobe ngwaọrụ mwepụ ígwè n'ọdụ ụgbọ mmiri mbupụ nke ịwụ, na a na-edobe ihe mgbakwunye mmiri n'elu ebe a na-agwakọta ihe iji tinye mmiri mgbe ọ na-akpali. Ọnụego mgbakwunye mmiri bụ 10L / min.
3. Ihe ihicha ihe: A na-akpọnwụ ihe mmiri mmiri mgbe agwakọtachara ya na akụrụngwa ihicha na okpomọkụ nke 120-150 ° C iji wepụ mmiri mmiri. Mgbe ihicha zuru oke, a na-ewepụta ihe ahụ maka oyi eke.
4. Nchicha na nyocha: Ihe akpọkọtara akpọnwụ akpọnwụ na-abanye na ngwa ngwepịa na nyocha maka tupu ihie, wee banye n'ọkpụkpụ mgbagha maka ịzọpịa ọzọ, ma na-agafe n'otu oge na ngwa nyocha 60-mesh. A na-eweghachi irighiri ihe karịrị 0.25mm maka imegharị ihe maka ịzọpịa, ịzọpịa, na nyocha ọzọ, ebe a na-eziga irighiri ihe dị obere karịa 0.25mm na hopper.
5. Nkwadebe ihe nke abụọ: A na-ebughachi ihe ndị dị na hopper mgbapụta azụ na igwe batching maka nkwadebe nke abụọ. A na-agbakwunye 50% nke silicon carbide n'oge nkwadebe nke abụọ. A na-ezigara ihe ndị ahụ mgbe nkwadebe nke abụọ na igwe na-agwakọta maka ịmegharị ọzọ.
6. Ngwakọta nke abụọ: N'oge usoro ngwakọta nke abụọ, a na-agbakwunye ihe ngwọta pụrụ iche na viscosity na hopper mix site na ngwọta pụrụ iche na-agbakwụnye ngwaọrụ nwere nnukwu ike ndọda. A na-atụ ihe ngwọta pụrụ iche site na ịwụ na-atụ aro ma tinye ya na hopper ngwakọta.
7. Ịpị na ịkpụzi: A na-eziga ihe ndị ahụ mgbe agwakọta nke abụọ gachara na igwe nrụnye nke isostatic. Mgbe nbudata, mkpirisi, ihicha, na ihicha na ebu, a na-agbanye ihe ndị ahụ n'ime igwe ịpị nke isostatic.
8. Ịcha na mkpụcha: Nke a na-agụnye ibelata ịdị elu na ibelata ihe ọkụkụ ndị nwere ike ime. A na-eji igwe na-egbutu osisi na-eme ka ọkpụkpụ na-eme ka ọkpụkpụ ahụ dị elu dị elu nke a chọrọ, na-eme ka ọkpụkpụ na-egbuke egbuke mgbe e gbuchara ya.
9. Ịkpọ nkụ: A na-ezigara crucible ahụ, mgbe e gbuchara ya ma dozie ya na nzọụkwụ (8), na-eziga ya na oven na-ekpo ọkụ maka ihicha, na-ekpo ọkụ nke 120-150 ° C. Mgbe ihichachara, a na-edebe ya ọkụ maka awa 1-2. A na-eji usoro ngbanwe ikuku ikuku, nke nwere ọtụtụ efere aluminom na-agbanwe agbanwe. A na-ahazi efere aluminom ndị a na-agbanwe agbanwe n'akụkụ abụọ dị n'ime nke oven ihicha, yana eriri ikuku n'etiti efere aluminom abụọ ọ bụla. A na-edozi oghere dị n'etiti efere aluminom abụọ ọ bụla iji dozie eriri ikuku.
10. Glazing: A na-eme glaze site na ịgwakọta ihe ndị na-egbuke egbuke na mmiri, gụnyere bentonite, ụrọ na-emegharị emegharị, ntụ ntụ iko, feldspar ntụ ntụ, na sodium carboxymethyl cellulose. A na-eji aka na-etinye glaze ahụ na ahịhịa n'oge glazing.
11. Mgbapụ nke mbụ: A na-agba ọkụ ahụ nwere glaze etinyere otu ugboro n'ime kiln maka awa 28-30. Iji kwalite ịrụ ọrụ nke ọma, a na-edobe akwa akwa akwa labyrinth nwere mmetụta akara na mgbochi ikuku na ala nke kiln. Ihe ndina kiln nwere akwa akwa mkpuchi mkpuchi, na n'elu owu mkpuchi, e nwere akwa brik mkpuchi, na-akpụ akwa akwa akwa akwa.
12. Impregnation: A na-etinye crucible a chụrụ n'ọkụ na tank nke impregnation maka agụụ na impregnation nrụgide. A na-ebufe ihe ngwọta impregnation na tank nke impregnation site na pipeline mechiri emechi, na oge impregnation bụ 45-60 nkeji.
13. Mgba egbe nke abụọ: A na-etinye crucible a na-agbanye n'ọkụ n'ime ọkụ maka ịgba egbe nke abụọ maka awa 2.
14. Mkpuchi: A na-eji agba acrylic resin na-eme ka mmiri kpuchie ihe mkpuchi ahụ mgbe agbapụ nke abụọ gasịrị.
15. Emechara ngwaahịa: Mgbe emechara mkpuchi ahụ, a na-akpọnwụ n'elu, ma mgbe akpọnwụchara, a na-akwakọba ihe mkpuchi ma chekwaa ya.
