Needle coke ndi mtundu wapamwamba kwambiri wopangidwa mwamphamvu ndi zida za kaboni. Maonekedwe ake ndi olimba porous ndi siliva imvi ndi zitsulo luster. Kapangidwe kake kamakhala ndi mawonekedwe owoneka bwino, okhala ndi mabowo akulu koma ochepa komanso mawonekedwe ozungulira pang'ono. Ndizopangira zopangira zinthu zopangira kaboni wapamwamba kwambiri monga ma elekitirodi amphamvu kwambiri, zida zapadera za carbon, kaboni fiber ndi zida zake zophatikizika.
Malinga ndi zida zosiyanasiyana zopangira, singano ya coke imatha kugawidwa m'magulu amafuta ndi makala amitundu iwiri ya singano. Sino coke yopangidwa ndi zotsalira za petroleum monga zopangira ndi mafuta angapo a singano coke. Sinono coke coke yopangidwa kuchokera ku phula la malasha ndipo gawo lake limatchedwa coal measure nele coke.
Ma index omwe amakhudza ubwino wa singano ya singano amaphatikizapo kachulukidwe weniweni, sulfure, zomwe zili ndi nayitrogeni, zomwe zimakhala zosasunthika, phulusa, kuchuluka kwa kutentha, mphamvu zamagetsi, kugwedezeka kwamphamvu, ndi zina zotero. agawidwe mu giredi yapamwamba (yapamwamba), giredi yoyamba ndi yachiwiri.
Kusiyana kwa magwiridwe antchito pakati pa singano ya singano ya malasha ndi singano ya singano yamafuta kumaphatikizapo mfundo zotsatirazi.
1. Pazifukwa zomwezo, ma elekitirodi a graphite opangidwa ndi mafuta angapo a singano ndi osavuta kupangidwa kuposa ma coke a singano a malasha potengera magwiridwe antchito.
2. Pambuyo popanga ma graphite, zopangidwa ndi graphitized za mafuta angapo a singano a coke zimakhala ndi kachulukidwe kakang'ono komanso mphamvu kuposa ya coke ya singano yamakala, yomwe imayamba chifukwa cha kuchuluka kwa singano yamakala nthawi ya graphitization.
3. Pogwiritsa ntchito ma elekitirodi a graphite, zinthu zopangidwa ndi graphite zokhala ndi singano yamafuta zimakhala ndi coefficient yotsika yakukulitsa matenthedwe.
4. Pankhani ya zolozera thupi ndi mankhwala a graphite elekitirodi, kukana zenizeni graphitized mankhwala mafuta angapo singano coke ndi apamwamba pang'ono kuposa malasha angapo singano mankhwala coke.
5. Chinthu chofunika kwambiri ndi chakuti coke coke singano imakula panthawi ya kutentha kwa graphitization, pamene kutentha kumafika 1500-2000 ℃, kotero kutentha kwa kutentha kuyenera kuyendetsedwa mosamalitsa, osati kutenthetsa mofulumira, ndi bwino kuti musamatenthe. gwiritsani ntchito kupanga graphitization process, malasha kuyeza singano coke powonjezera zowonjezera kuti muwongolere kukula kwake, kukulitsa kumatha kuchepetsedwa. Koma ndizovuta kwambiri kukwaniritsa mafuta - zochokera singano coke.
6. Makina opangira mafuta a calcined amakhala ndi ma coke ang'onoang'ono komanso kukula kwake kwambewu, pomwe singano yoyezera malasha imakhala ndi ma coke ochepa komanso kukula kwake kwambewu (35-40 mm), komwe kumatha kukwaniritsa kukula kwambewu, koma kumabweretsa zovuta. kwa kuphwanya kwa wogwiritsa.
7. Malinga ndi Japan Petroleum Coke Company, amaonedwa kuti zikuchokera mafuta angapo singano coke ndi yosavuta kuposa malasha angapo singano coke, kotero n'zosavuta kulamulira pa ndondomeko kuphika.
Kuchokera pamalingaliro apamwamba, makina a singano a mafuta ali ndi anayi otsika: mphamvu yokoka yochepa, mphamvu yochepa, CTE yochepa, kukana kwenikweni, awiri oyambirira otsika pa mankhwala a graphite, awiri otsiriza otsika pa mankhwala a graphite ndi abwino. Nthawi zambiri, mawonekedwe amafuta amtundu wa singano ndi abwino kuposa amtundu wa singano zamakala, ndipo kufunikira kwa ntchito ndikokulirapo.
Pakadali pano, ma elekitirodi a graphite ndiye msika wofunikira kwambiri wa singano, womwe umawerengera pafupifupi 60% ya kuchuluka kwa singano ya singano, ndipo mabizinesi amagetsi amafunikira zomveka bwino za singano za coke, popanda kufunikira kwamunthu payekha. Lithium ion battery anode zipangizo zimakhala ndi mitundu yosiyanasiyana ya coke ya singano, msika wapamwamba wa digito umakonda coke yophika mafuta, msika wa batri wamagetsi umadalira kwambiri coke yaiwisi yotsika mtengo.
Kupanga singano coke kuli ndi luso linalake, kotero pali ochepa mabizinesi apakhomo. Pakali pano, odziwika bwino m'nyumba mafuta angapo singano opanga coke monga Shandong Jingyang, Shandong Yida, Jinzhou Petrochemical, Shandong Lianhua, Bora Biological, Weifang Fumei New Energy, Shandong Yiwei, Sinopec Jinling Petrochemical, Maoming Petrochemical, etc. singano coke ndi Baowu Carbon Material, Baotailong Technology, Anshan Kaitan, Angang Chemical, Fang Daxi Kemo, Shanxi Hongte, Henan Kaitan, Xuyang Gulu, Zaozhuang Zhenxing, Ningxia Baichuan, Tangshan Dongri New Energy, Taiyuan Shengxu, etc.
