Mwachidule graphite yolimba

Kulemeletsa
Graphite yolimbaamapangidwa kuchokera ku glake grakefute ngati zinthu zazikuluzikulu, ndipo zimakonzedwa ndi dongo lokhazikika la pulasitiki kapena kaboni ngati bina. Ili ndi mawonekedwe a kutentha kwambiri kukana, mawonekedwe amphamvu, omwe amatsutsana bwino, komanso moyo wautumiki. Nthawi yotentha kwambiri, kulumikizana kwa kutentha kwa matermal ndizochepa, ndipo kumakhala ndi vuto linalake kuti liziwa kuzizira komanso kutentha. Ili ndi kuthetsa kwamphamvu kwa acidic ndi alkaline, kukhazikika kwamphamvu kwa mankhwala, ndipo sikutenga nawo mbali pamavuto aliwonse omwe akusungunuka. Khoma lamkati la graphite yolimba ndi yosalala, ndipo mafuta a chitsulo chosungunuka siophweka kudontha wamkati, ndikupangitsa kuti madzi azikhala ndi maluwa abwino ndikupanga nkhungu zosiyanasiyana. Chifukwa cha zinthu zabwino kwambiri, zojambulajambula zojambulajambula zimagwiritsidwa ntchito kwambiri pakupanga zitsulo za alloy ndi zitsulo zosakhala zopweteka komanso zopondapo zawo.

Mtundu
Ziphuphu zojambulajambula zimagwiritsidwa ntchito makamaka chifukwa cha zosungunuka zachitsulo, zomwe zimagawidwa m'magulu awiri: zachilengedwe zojambula ndi zojambula zopangira.
1) yachilengedwe yachilengedwe
Zimapangidwa makamaka ndi grakiti yachilengedwe ngati zinthu zazikuluzikulu, zowonjezera dongo ndi zida zina zopangira. Nthawi zambiri zimatchedwa graphte yopambana, pomwe pali mtundu wopaka za kaboni wopangidwa ndi phula ngati phula. Zimangopangidwa ndi gulu lankhondo la dongo ndipo limatchedwa mtundu wa Hui Claus wopalamula. Woyamba ali ndi mphamvu zapamwamba komanso zoopsa. Amagwiritsidwa ntchito posungunuka kwa chitsulo, mkuwa, mkuwa, ndi zitsulo zina zopanda pake, zokhala ndi mapiri osiyanasiyana komanso ma carties osiyanasiyana omwe amasungunuka kuyambira 250g mpaka 500kg.
Mtundu uwu wapamwamba umaphatikizapo zowonjezera ngati supuni yowoneka, chivindikiro, mphete yolumikizira, thandizo lolimba, komanso ndodo yolimba.
2) Graphite yopanga
Mphamvu zachilengedwe zotchulidwa pamwambapa nthawi zambiri zimakhala ndi michere ya 50%, pomwe zonyansa (phulusa) mu zojambulajambula zojambulajambula ndizosakwana 1%, zomwe zimagwiritsidwa ntchito poyeza zitsulo zoyera kwambiri. Palinso graphite yapamwamba kwambiri yomwe yatsuka mankhwala apadera (phulusa la 20ppm). Zojambulajambula zojambula zojambula nthawi zambiri nthawi zambiri zimagwiritsidwa ntchito kusungunula zitsulo zazing'ono, zitsulo zoyera kwambiri, kapena zitsulo zosungunuka komanso ma okondedwa. Itha kugwiritsidwanso ntchito ngati chopatsirana pakuwunika kwa mpweya mu chitsulo.

Njira Zopangira
Njira zopangira zojambulajambula zimatha kugawidwa m'mitundu itatu: Kuumba dzanja lamanja, kuzungulira kwa dzanja, komanso kusokoneza. Khalidwe la chopachikidwa limagwirizana kwambiri ndi njira younikira. Njira yopanga imawonetsera kapangidwe kake, kachulukidwe, kapangidwe kake kamphamvu kake.
Zovala zamanja zopangidwa ndi zolinga zapadera sizingapangidwe pogwiritsa ntchito njira zosinthira kapena kuwononga. Zovala zina zapadera zomwe zimapangidwa ndi zopangidwa mwapadera zimatha kupangidwa pophatikiza zonena ndi zoumba zamitundu.
Kuumba kozungulira ndi njira yomwe makina amatha kuzungulira amayendetsa nkhungu kuti azigwira ntchito ndipo amagwiritsa ntchito mpeni wamkati kuti amataye kuti ubweya wopanduka.
Makina osokoneza bongo ndi mankhwala osokoneza bongo monga kuthamanga kwa mafuta, kukakamizidwa kwamadzi, kapena kukakamizidwa kwa madzi, monga mphamvu zachitsulo monga zida za pulasitiki zopangira zojambulajambula. Poyerekeza ndi njira yosinthira, ili ndi zabwino zokhala zosavuta, kuzungulira kwakanthawi kochepa, kukolola kwakukulu, kuwumba kochepa, chinyezi chotsika, mawonekedwe otsika mtengo.

Chisamaliro ndi Kusungitsa
Ziphuphu zojambula ziyenera kutetezedwa ku chinyontho. Ziwawa zojambulajambula zimawopa kwambiri chinyezi, chomwe chingayambitse kwambiri. Ngati atagwiritsidwa ntchito ndi chiwongola dzanja, chimatha kuyambitsa kusokonekera, kuphulika, m'mphepete mwamphamvu, ndikugwa pansi, zomwe zimapangitsa kuti zitsulo zosungunule komanso ziwopsezo zokhudzana ndi ntchito. Chifukwa chake, posungira ndi kugwiritsa ntchito zida zojambulajambula, chidwi chiyenera kupulumutsidwa kuti chinyezipe popewa.
Nyumba yosungiramo nyumba yosungirako zokopa iyenera kukhala youma komanso yopumira, ndipo kutentha kumayenera kusungidwa pakati pa 5 ℃ ndi 25 ℃, ndi chinyezi cha 50-60%. Ziphuphu siziyenera kusungidwa panthaka ya njerwa kapena malo a simenti kuti mupewe chinyontho. Chingwe chochuluka cha graphit chimayenera kuyikidwa pamatabwa, makamaka 25-30cm pamwamba pa nthaka; Kutalikirana mabokosi a matabwa, mabasiketi oyaka, kapena matumba a udzu, ogona ayenera kuyikidwa pansi pa pallets, osachepera 20cm pamwamba pa 20cm pamwamba pa nthaka. Kuyika wosanjikiza kwa momwe akumvera kumagonako kumakhala kovuta kwambiri chinyezi. Panthawi yokhazikika, ndikofunikira kuti muchepetse mawonekedwe apansi pansi, makamaka ndi zigawo zapamwamba komanso zotsika zomwe zimayang'anizana. Kukhazikika pakati pa malo osakhazikika sikuyenera kukhala motalika kwambiri. Nthawi zambiri, kukhazikika kumayenera kuchitikira kamodzi miyezi iwiri iliyonse. Ngati chinyezi chapansi sichili chambiri, kukhazikika kungachitike kamodzi miyezi itatu iliyonse. Mwachidule, kukhazikika pafupipafupi kumatha kukwaniritsa chinyezi.
