Mu rwego rw’itanura ry’inganda zifite ubushyuhe bwo hejuru (nko guhindura ibyuma, ingoro, n’itanura riturika),amatafari ya karuboneuhagarare nkibikoresho byingenzi bivunika, tubikesha uburyo bwiza bwo kurwanya ruswa, ubushyuhe bwo hejuru, hamwe nubushyuhe bwumuriro. Igikorwa cyo kubyaza amatafari ni ihuriro rikomeye ryikoranabuhanga kandi risobanutse - buri ntambwe igena ubwiza bwibicuruzwa byanyuma. Hasi, turakunyuze mubikorwa byuzuye byo gukora amatafari ya karubone ya magnesium, tugaragaza uburyo twemeza ko amatafari yose yujuje ubuziranenge bwinganda.
1. Guhitamo Ibikoresho Byibanze: Urufatiro rwamatafari ya karubone nziza cyane
Ubwiza bwibikoresho fatizo numurongo wambere wo kwirwanaho kubikorwa bya magnesium karubone. Twubahiriza ibipimo ngenderwaho byo gutoranya kugirango buri kintu cyujuje ubuziranenge:
Igiteranyo Cyinshi cya Magnesia Igiteranyo:Dukoresha magnesia yahujwe cyangwa magnesia yacumuye hamwe na MgO irenga 96%. Ibikoresho bibisi bitanga amatafari hamwe nubushyuhe bwo hejuru bwo guhangana nubushyuhe bwo kurwanya ruswa, bikarwanya neza isuri yicyuma gishongeshejwe hamwe nigitereko mumatanura.
Urwego rwohejuru rwa Carbone Inkomoko:Imiterere ya flake isanzwe ifite karubone ya 90% + yatoranijwe. Imiterere yacyo itezimbere amatafari yo kurwanya amashyanyarazi, bikagabanya ibyago byo guturika bitewe nubushyuhe bwihuse mugihe cyo gukora itanura.
Binder Premium:Fenolike resin (yahinduwe kubushyuhe bwo hejuru) ikoreshwa nka binder. Iremeza isano ikomeye hagati ya magnesia na grafite, mugihe wirinze guhindagurika cyangwa kubora mubushyuhe bwinshi, ibyo bikaba byagira ingaruka kumatafari.
Kurikirana inyongera:Umubare muto wa antioxydants (nk'ifu ya aluminium, ifu ya silicon) hamwe nibikoresho bifasha gucumura byongeweho kugirango wirinde okiside ya grafite kandi bitezimbere ubwinshi bwamatafari. Ibikoresho byose bibisi bikorerwa ibice 3 byipimisha kugirango bikureho umwanda ushobora guca intege imikorere.
2. Kumenagura no Gusya: Kugereranya Ingano Nini Kugenzura Imiterere imwe
Ingano zingana zingana ni urufunguzo rwo kwemeza ubwinshi n'imbaraga z'amatafari ya karubone. Iki cyiciro gikurikiza ibipimo bya tekiniki:
Kumenagura inzira:Ubwa mbere, magnesia nini na grafite byajanjaguwe mo uduce duto ukoresheje urusyo rwimitsi. Umuvuduko wo kumenagura ugenzurwa saa 20-30 rpm kugirango wirinde gushyuha no kwangiza imiterere yibikoresho.
Kugaragaza no Gutondekanya:Ibikoresho byajanjaguwe bisuzumwa hifashishijwe ibice byinshi byinyeganyeza (hamwe nubunini bwa mesh bwa 5mm, 2mm, na 0.074mm) kugirango ubitandukanyirize hamwe (3-5mm), igiteranyo giciriritse (1-2mm), igiteranyo cyiza (0.074-1mm), nifu ya ultrafine (<0.074mm). Ingano yubunini bugenzurwa muri ± 0.1mm.
Granule Homogenisation:Ingano zitandukanye zingana zivanze mumuvuduko mwinshi wivanga muminota 10-15 kumuvuduko wa 800 rpm. Ibi byemeza ko buri cyiciro cya granules gifite imiterere ihamye, igashyiraho urufatiro rwubucucike bwamatafari amwe.
3. Kuvanga no gupfukama: Kugera ku Guhuza Gukomeye Hagati y Ibigize
Icyiciro cyo kuvanga no guteka kigena imbaraga zo guhuza ibikoresho fatizo. Twifashishije ivanga rya kabiri-helix kandi tugenzura neza imikorere:
Mbere yo Kuvanga Ibikoresho Byumye:Igiteranyo cyoroheje, giciriritse, kandi cyiza kibanza kuvangwa byumye muminota 5 kugirango habeho no kugabura buri kintu. Iyi ntambwe irinda kwibanda kwa karubone cyangwa magnesia, bishobora gutera itandukaniro ryimikorere.
Ongeraho Guhambira no Gupfukama:Ihindurwa rya fenolike (yashyutswe kugeza kuri 40-50 ℃ kugirango amazi meza) yongerwe kumuvange wumye, hakurikiraho iminota 20-25 yo gukata. Ubushyuhe bwa mixer` bugumana kuri 55-65 ℃, kandi umuvuduko ukagengwa na 0.3-0.5 MPa - ibi bituma binder yuzuza buri kintu cyose, igakora imiterere "magnesia-graphite-binder" ihamye.
Kwipimisha Guhoraho:Nyuma yo gukata, kuvanga` guhora bigeragezwa buri minota 10. Ihame ryiza ni 30-40 (bipimwa na metero isanzwe ihoraho); niba byumye cyane cyangwa bitose, dosiye ya binder cyangwa igihe cyo gukata ihindurwa mugihe nyacyo.
4. Gukora Kanda: Gushiraho Umuvuduko Ukabije Kubyinshi nimbaraga
Gukora kanda nintambwe itanga amatafari ya karubone ya magnesium imiterere yanyuma kandi ikemeza ubwinshi. Dukoresha imashini zikoresha hydraulic zikoresha kugenzura neza umuvuduko:
Gutegura ibishushanyo:Ibishushanyo byabugenewe byabigenewe (ukurikije ibisabwa nabakiriya kubunini bwamatafari, nka 230 × 114 × 65mm cyangwa ubunini bwihariye) birasukurwa kandi bigashyirwaho umukozi wo kurekura kugirango birinde kuvanga gukomera.
Kanda cyane:Imvange ikaranze isukwa mubibumbano, imashini ya hydraulic ikoresha umuvuduko wa 30-50 MPa. Umuvuduko wo gukanda ushyizwe kuri 5-8 mm / s (gukanda buhoro kugirango ukureho umwuka mwinshi) kandi ufashwe amasegonda 3-5. Ubu buryo butuma ubwinshi bwamatafari bugera kuri 2,8-3.0 g / cm³, hamwe nubushake buri munsi ya 8%.
Kugaragaza no Kugenzura:Nyuma yo gukanda, amatafari aramanurwa mu buryo bwikora hanyuma akagenzurwa ku busembwa bwo hejuru (nk'ibice, impande zingana). Amatafari afite inenge ahita yangwa kugirango yirinde kwinjira mubikorwa bikurikira.
5. Kuvura Ubushyuhe (Gukiza): Kuzamura Guhuza no Guhagarara
Kuvura ubushyuhe (gukiza) bishimangira ingaruka zihuza kandi bikuraho ibintu bihindagurika mumatafari. Dukoresha itanura rya tunnel hamwe no kugenzura ubushyuhe bwuzuye:
Gushyushya Intambwe: Amatafari ashyirwa mu itanura rya tunnel, kandi ubushyuhe burazamuka buhoro buhoro:
20-80 ℃ (amasaha 2):Guhumeka neza;
80-150 ℃ (amasaha 4):Guteza imbere resin gukira;
150-200 ℃ (amasaha 6):Byuzuye resin guhuza no gukiza;
200-220 ℃ (amasaha 3):Shimangira imiterere y'amatafari.
Igipimo cyo gushyuha kigenzurwa kuri 10-15 ℃ / saha kugirango wirinde gucika bitewe nubushyuhe bwumuriro.
Kurandura ibintu bihindagurika:Mugihe cyo gukira, ibice bihindagurika (nkibisigarira bito bya molekile) bisohoka binyuze muri sisitemu yo gucana itanura, byemeza ko amatafari yimbere yimbere kandi yuzuye ubusa.
Uburyo bwo gukonjesha: Nyuma yo gukira, amatafari akonjeshwa ubushyuhe bwicyumba ku gipimo cya 20 ℃ / saha. Gukonjesha byihuse birindwa kugirango wirinde kwangirika kwubushyuhe.
6. Nyuma yo gutunganya no kugenzura ubuziranenge: Kureba ko amatafari yose yujuje ubuziranenge
Icyiciro cya nyuma cy'umusaruro cyibanda ku gutunganya neza no gupima ubuziranenge kugira ngo buri matafari ya karubone ya magnesium yujuje ibisabwa mu nganda:
Gusya no gutema:Amatafari afite impande zingana ni hasi ukoresheje imashini zisya CNC, zemeza ko ikosa rinini riri muri ± 0.5mm. Amatafari afite imiterere yihariye (nk'amatafari ameze nk'ay'amatafari ahindura) atunganywa hifashishijwe ibigo bitunganya 5-axis kugirango bihuze n'urukuta rw'imbere rw'urukuta rw'imbere.
Ikizamini Cyuzuye Cyuzuye:Buri cyiciro cyamatafari gikorerwa ibizamini 5 byingenzi:
Ikigereranyo n'ubucucike:Ukoresheje uburyo bwa Archimedes, menya ubwinshi bwinshi ≥2.8 g / cm³ hamwe nubushake ≤8%.
Ikizamini Cyimbaraga Zikomeye:Gerageza amatafari yo gukomeretsa (≥25 MPa) ukoresheje imashini igerageza isi yose.
Ikizamini cyo Kurwanya Ubushyuhe:Nyuma yinzinguzingo 10 zo gushyushya (1100 ℃) no gukonjesha (ubushyuhe bwicyumba), genzura ibice (nta bice bigaragara byemewe).
Ikizamini cyo Kurwanya Ruswa:Gereranya itanura kugirango ugerageze kurwanya amatafari yo kurwanya isuri yashonze (igipimo cy'isuri ≤0.5mm / h).
Isesengura ryibigize imiti:Koresha X-ray fluorescence spectrometry kugirango urebe ibirimo MgO (≥96%) nibirimo karubone (8-12%).
Gupakira no kubika:Amatafari yujuje ibyangombwa apakirwa mu makarito adafite ubushuhe cyangwa pallet yimbaho, hamwe na firime itagira ubushyuhe kugira ngo irinde kwinjiza amazi mu gihe cyo gutwara. Buri paki yanditseho nimero yicyiciro, itariki yatangiweho, nicyemezo cyubugenzuzi bwiza kugirango gikurikiranwe.
Kuki Guhitamo Amatafari ya Carbone Magnesium?
Igikorwa cyacu gikora cyane (kuva guhitamo ibikoresho fatizo kugeza nyuma yo gutunganywa) byemeza ko amatafari ya karubone ya magnesium afite imikorere myiza mumatanura yubushyuhe bwo hejuru. Haba kubihindura ibyuma, ingeri, cyangwa ibindi bikoresho byo hejuru cyane, ibicuruzwa byacu birashobora:
Ihangane ubushyuhe bugera kuri 1800 ℃ utarinze koroshya cyangwa guhindura ibintu.
Irinde ibyuma bishongeshejwe hamwe nisuri ya slag, wongere ubuzima bwumuriro 30% +.
Kugabanya inshuro zo kubungabunga no gutanga umusaruro kubakiriya.
Dutanga ibisubizo byihariye ukurikije ubwoko bwitanura, ingano, nuburyo bukora. Twandikire uyumunsi kugirango umenye byinshi kubijyanye no gutunganya amatafari ya karubone ya magnesium cyangwa kugirango ubone amagambo yubusa!
