Ndi zolakwika ziti zosasinthika zomwe zidzachitike mu ndondomeko yotsatira ya graphitization chifukwa cha "kutentha pang'ono" calcination?

Coke "yosapsa bwino" yokhala ndi calcium, chifukwa cha kusakwanira kwa calcium mu zinthu zopangira, imayambitsa zolakwika zamkati mwa kapangidwe kake panthawi ya graphitization yotsatira, zomwe zimayambitsa zolakwika zosasinthika monga ming'alu, kuchuluka kosafanana, kuchepa kwa voliyumu kosazolowereka, komanso kuchepa kwa magwiridwe antchito pazinthu zopangidwa ndi graphit. Kusanthula mwatsatanetsatane kuli motere:

Zotsatira Zachindunji za Kusakwanira kwa Calcination ya Zipangizo Zatsopano

Kuyika calcination ndi gawo lofunika kwambiri musanayambe kuyika graphitization, cholinga chake ndi kulola zinthu zosasunthika mkati mwa zinthu zopangira (monga petroleum coke ndi needle coke) kutuluka kudzera mu kutentha kwambiri, kuchepetsa kuchuluka kwa zinyalala, ndikupanga kapangidwe koyenera ka pore. Ngati calcination sikokwanira (mwachitsanzo, "yosapsa mokwanira"), zinthu zambiri zosasunthika komanso zinyalala zosasinthika zidzatsala mu zinthu zopangira. Zotsalira izi zidzapitiriza kuwola kapena kuchitapo kanthu panthawi ya kuyika graphitization pambuyo pake, zomwe zimayambitsa kutuluka kwa mpweya kapena kusintha kwa mankhwala mkati mwa zinthuzo, zomwe zimapangitsa kuti pakhale zolakwika m'mapangidwe.

Zolakwika Zosasinthika Zomwe Zimachitika Panthawi ya Graphitization

Zolakwika za Ming'alu:

• Chifukwa cha Kapangidwe: Zinthu zotsalira zosasunthika komanso zodetsa zomwe zili mu coke yomwe siikupsa bwino zimawola mwachangu kapena kuchitapo kanthu kutentha kwambiri kwa graphitization, zomwe zimapangitsa mpweya wambiri. Mpweya uwu umasonkhana mkati mwa chinthucho ndipo umafuna njira zotulukira; ngati sungatulutsidwe munthawi yake, umapanga kuthamanga kwakukulu mkati mwa chinthucho, zomwe zimapangitsa kuti ming'alu ipangidwe. Kuphatikiza apo, kapangidwe ka ma pore osafanana a coke yomwe siikupsa bwino ingayambitse kufalikira kwa kutentha kosagwirizana panthawi ya graphitization, zomwe zimapangitsa kuti ming'alu ipangidwe kwambiri.
• Kuwonongeka: Ming'alu imachepetsa mphamvu ya makina ndi mphamvu yamagetsi ya chinthucho ndipo ingayambitse kusweka panthawi yokonza kapena kugwiritsa ntchito.

Kuchulukana Kosafanana:

• Chifukwa cha Kapangidwe: Kapangidwe ka ma pore osafanana a coke yomwe siyaka bwino imayambitsa kusamuka kosasinthasintha kwa zinthu ndi kuchulukana kwa zinthu panthawi ya graphitization. Madera ena akhoza kukhala ndi kuchulukana kosakwanira chifukwa cha kuchuluka kwa ma pore, pomwe ena amatha kukhala ndi nkhawa chifukwa cha kuchulukana kwambiri.
• Zotsatira: Kuchulukana kosagwirizana kumakhudza zizindikiro zazikulu za magwiridwe antchito a chinthucho, monga kuyendetsa magetsi, kuyendetsa kutentha, ndi mphamvu ya makina.

Kuchepa kwa Volume Kosazolowereka:

• Chifukwa cha Kupangika: Coke yosapsa bwino imatha kuchepetsedwa kwambiri panthawi ya graphitization chifukwa cha kuwonongeka kwa zinthu zotsalira kapena momwe zinthu zosafunika zimachitikira. Kuchepa kumeneku kungayambitse kusakhazikika kwa kukula kwa zinthu komanso kusintha kwa zinthu.
• Zotsatira: Kuchepa kwa voliyumu kosazolowereka kumakhudza kulondola kwa miyeso ndi magwiridwe antchito a chinthucho, zomwe zimachepetsa ubwino wake wonse.

Kuwonongeka kwa Magwiridwe Antchito:

• Chifukwa cha Kapangidwe: Chifukwa cha kukhalapo kwa zolakwika zomwe zatchulidwa pamwambapa, zinthu zopangidwa ndi graphitized zopangidwa kuchokera ku coke yomwe siikuyaka bwino zitha kukhala ndi mphamvu zochepa zamagetsi, kutentha, komanso mphamvu zamakaniko poyerekeza ndi zomwe zimapangidwa kuchokera ku coke yomwe ili ndi calcium yoyenera.
• Zotsatira: Kuchepa kwa magwiridwe antchito kumachepetsa kukula kwa ntchito ndi moyo wautumiki wa chinthucho, zomwe zimachepetsa mpikisano wake pamsika.
