Cov lus nug nquag
Cov lus teb zoo rau cov lus nug ntau los ntawm peb cov neeg siv khoom thoob ntiaj teb.
Graphitized Petroleum Coke (GPC) siv rau dab tsi?
GPC feem ntau yog siv los ua lub siab -kev ua tau zoo recarburizer (carbon additive) hauv steelmaking thiab foundry los kho cov ntsiab lus carbon. Nws kuj yog ib qho tseem ceeb raw khoom rau graphite electrodes, lithium{2}}ion roj teeb anodes, crucibles, thiab cov khoom tshwj xeeb carbon.
Dab tsi yog cov tshuaj muaj pes tsawg leeg ntawm GPC?
Hwm GPC feem ntau muaj 98.5–99.5% taag carbon, sulfur Tsawg dua los yog sib npaug rau 0.05%, tshauv Tsawg dua los yog sib npaug rau 0.5–1.0%, volatile teeb meem tsawg dua los yog sib npaug rau 0.5%, thiab nitrogen Tsawg dua los yog sib npaug rau 300ppm. Cov qib purity siab dua rau kev siv roj teeb tuaj yeem ncav cuag 99.9% carbon nrog sulfur Tsawg dua lossis sib npaug li 0.01%.
GPC txawv ntawm Calcined Petroleum Coke (CPC) li cas?
CPC is heat-treated at 1200–1500°C to remove volatiles. GPC undergoes additional graphitization at 2800–3000°C, which rearranges carbon atoms into an ordered graphite structure. This gives GPC much lower resistivity (≤20 μΩ·m vs ~500 μΩ·m for CPC), lower sulfur (≤0.05% vs ~0.5%), higher true density, and better absorption rate (>95% vs 80-90%).
Dab tsi particle loj muaj rau GPC?
Peb muab ntau qhov ntau thiab tsawg: 0-1mm (hmoov), 0.5-5mm, 1-5mm, 2-6mm, 5-15mm, 8-26mm, thiab 25-50mm (khoom). Qhov ntau thiab tsawg yog muaj nyob rau hauv kev thov kom haum rau koj cov txheej txheem melting lossis casting.
Dab tsi yog qhov nqus ntawm GPC hauv cov hlau molten?
Graphitized petroleum coke muaj cov pa roj carbon ntau dua 95% hauv cov hlau molten, ntau dua li calcined petroleum coke (80–90%) thiab semi-graphitized coke (75–85%). Qhov no txhais tau tias tsawg dua cov khoom siv, txo cov nqi tag nrho.
Koj GPC ua raws li ntawv pov thawj dab tsi?
Peb cov graphitized petroleum coke yog tsim nyob rau hauv ISO 9001: 2015 thiab ISO 14001: 2015 certified chaw. Peb muab RoHS, REACH, thiab CA65 ua raws, nrog Daim Ntawv Pov Thawj Kev Ntsuam Xyuas (COA) rau txhua pawg. Thib peb-kev soj ntsuam tog (SGS, BV) tuaj yeem npaj.
GPC puas tuaj yeem siv rau lithium roj teeb anodes?
Yog lawm. High-purity GPC (Ntau dua lossis sib npaug rau 99.9% carbon, sulfur Tsawg dua lossis sib npaug li 0.01%, tshauv Tsawg dua lossis sib npaug li 0.03%, thiab cov kab kawm tsawg dua lossis sib npaug li 50ppm) yog cov khoom siv zoo tshaj plaws rau cov khoom siv hluavtaws graphite anodes hauv lithium {{6}.} Nws qib siab graphitization (Ntau dua lossis sib npaug li 95%) ua kom muaj kev ua tau zoo thiab kev ua haujlwm zoo.
Dab tsi yog qhov txawv ntawm GPC thiab semi-graphitized petroleum coke?
Semi-graphitized coke undergoes insufficient heat treatment, leaving disordered carbon structures. GPC is fully graphitized at ~3000°C, giving it lower sulfur (≤0.05% vs 0.3–0.7%), higher fixed carbon (≥98% vs 93–97%), better absorption (>95% vs 75-85%), thiab muaj peev xwm nucleation zoo tshaj rau cam khwb cia hlau. Semi-graphitized coke yog pheej yig dua (30–50% tus nqi qis) thiab haum rau cov ntawv thov tsawg dua.
Lub sij hawm coj mus kuaj rau kev txiav txim thoob ntiaj teb yog dab tsi?
Rau cov qauv qib thiab qhov ntau thiab tsawg, lub sijhawm ua haujlwm yog 15-20 hnub tom qab kev txiav txim pom zoo. Cov kev cai tshwj xeeb yuav xav tau 25-30 hnub. Peb muaj warehouses nyob ze cov chaw nres nkoj loj hauv Suav teb rau kev xa khoom ceev mus rau Tebchaws Europe, Asmeskas, Southeast Asia, thiab Middle East.
