Ụdị Ngwa Carbide Nozzle Scenario Mgbakwunye na Mmepụta Uru

Carbide nozzles bụ ihe ndị ziri ezi emere site na ijikọ ihe ndị nwere carbide siri ike (nke bụ tungsten carbide, WC) nwere ihe nkedo ọla (dịka cobalt, Co). Na-anya isi ike nke Vickers nke karịrị 1300 HV, ezigbo nguzogide eyi (ugboro 10-20 dị elu karịa nchara dị elu), yana nkwụsi ike nke okpomọkụ, ha aghọwo akụkụ isi na-enweghị atụ na ngalaba dị ka nhazi ụlọ ọrụ, ike, na ngwá electronic. Isi ihe na-eme ka uru ngwa ha dịkwuo elu bụ ngbanwe ụdị ọnọdụ - dabara na ụdị nozzles ziri ezi na ọnọdụ ọrụ akọwapụtara maka ịhazi arụmọrụ, ịdịte aka na ọnụ ahịa.

N'ime ọnọdụ nhazi jet abrasive, gụnyere sandblasting maka iwepụ nchara nchara na oke mmiri jet na-egbutu efere ígwè, a na-emetụta mgbidi dị n'ime nozzle ma na-agbaji site na ọsọ ọsọ (ruo 800 m / s) abrasive particles (dịka, alumina, silicon carbide). Maka nke a, ezigbo ọka carbide nozzles (nke nwere tungsten carbide nha nke 0.5-1μm) bụ nhọrọ kacha mma. Igwe microstructure ha dị oke oke na-ebelata ntinye nke irighiri ihe na-emebi emebi, na-ebelata ọnụ ahịa mgbidi dị n'ime nke ukwuu - na-agbatị ndụ ọrụ site na ugboro 3-5 ma e jiri ya tụnyere seramiiki ọdịnala na ibelata oge ndochi anya.

N'ihi na elu okpomọkụ ụlọ ọrụ ndapụta dị ka metal smelting flue gas ọcha na n'efu incineration iyuzucha ọgwụgwọ, nozzles ga-nagide ogologo oge ikpughe na 800-1000 ℃ elu okpomọkụ ka ịnọgide na-enwe airflow kwụsie ike. N'ebe a, tungsten-cobalt carbide nozzles (nke nwere ọdịnaya cobalt nke 6%-8%) na-arụ ọrụ nke ọma. Ihe na-ekekọta cobalt na-etolite njikọ kwụsiri ike na ọka tungsten carbide, na-egbochi mgbawa nhazi nke ihe ujo ọkụ na-eme na ịgba mbọ na-agbanwe agbanwe, nke dị oke mkpa maka nrụpụta gas flue nke ọma na iwepu uzuzu.

Na mpaghara nnyefe mmiri ziri ezi dị ka ihicha mgbawa semiconductor na mkpuchi LCD, ọbụlagodi obere ọgba aghara mmiri nwere ike bute mpe mpe mpe mpe mpe (dịka ọmụmaatụ, 0.1μm-scale scratches) n'elu ngwaahịa. Nozzles carbide na-egbuke egbuke-nke nwere mgbidi dị n'ime ime nke Ra≤0.02μm (enwetara site na nhazi nkenke nke ọkwa 12) -wepụ eddies mmiri, na-eme ka mkpuchi mkpuchi nke otu (nke na-erughị 5%) ma na-ezute ihe achọrọ nke ọma nke ụlọ ọrụ semiconductor.

Maka gburugburu ebe a na-egwuputa ihe dị arọ (dịka ọmụmaatụ, mkpochapụ uzuzu uzuzu na ụgbọ mmiri na-arụ ọrụ ịnweta), nozzles na-eche ihe ịma aka abụọ ihu: nkukota igwe sitere na coal/oke iberibe nkume na corrosion sitere na mmiri bara ụba nke ịnweta. Ọkpụkpụ carbide nwere nnukwu mgbidi (nke nwere mgbidi nke 5-8mm, 2-3 ugboro nke ọkọlọtọ nozzles) na mkpuchi mgbochi corrosion elu (dịka ọmụmaatụ, chromium plating) dozie nsogbu a. Ha na-ebelata ugboro ole nnọchi site n'elu 60% ma e jiri ya tụnyere ígwè nozzles nkịtị, na-ebelata ụgwọ ọrụ maka ụlọ ọrụ na-egwuputa ihe.

Nghọta uru nke nozzles carbide sitere na ụdị mmekọrịta dị omimi a. Site n'ịkwado usoro ihe onwunwe (dịka ọmụmaatụ, imezi ọdịnaya cobalt), nhazi nhazi (dịka ọmụmaatụ, mgbidi na-egbuke egbuke), na nhazi nhazi (dịka ọmụmaatụ, ultra-fine polishing) maka mkpa ụlọ ọrụ dị iche iche, ọ bụghị nanị na ha belata ụgwọ ọrụ site na 30% -50% ma melite nrụpụta mmepụta site na 20%-30n-technology-mmepe dị elu ma na-akwado njedebe ubi. Mpempe akụrụngwa ikuku ikuku (na-achọ nozzles nwere nha nha nke ± 0.005mm). Dị ka ụlọ ọrụ dị ka ume ọhụrụ, semiconductor, na aerospace na-agbaso ụkpụrụ arụmọrụ dị elu, nhazi nhazi nke carbide nozzles ga-emepewanye ikike ha, na-aghọ onye isi ihe maka nkwalite mmepụta ihe na mmepe dị elu.
