Kugwiritsa ntchito graphite yoyera kwambiri: Ufa wa graphite. N’chifukwa chiyani ufa wa graphite uli wotchuka kwambiri? Msika wamkati wa ma heater a graphite ukuyembekezeka kukhala wabwino. N’chifukwa chiyani ma heater a graphite akuchulukirachulukira pakati pa anthu? Ndipotu, chifukwa chake chikuchulukirachulukira pakati pa anthu sichingasiyanitsidwe ndi ubwino wake. Tsopano, tiyeni tiwone pamodzi ubwino weniweni wa heater ya graphite!
1. Zimachotsa kwathunthu okosijeni ndi kuchotsa kabotolo pamalo ogwirira ntchito panthawi yotenthetsera, ndipo zimatha kupeza malo oyera opanda wosanjikiza wowonongeka. Izi ndizofunikira kwambiri pakukweza magwiridwe antchito odulira zida zomwe zimangopera mbali imodzi yokha panthawi yopukutira (monga zobowola zopindika pomwe wosanjikiza wochotsa kabotolo pamalo opukutira umaonekera mwachindunji kumalire odulira pambuyo popukutira).
2. Sizimayambitsa kuipitsa chilengedwe ndipo sizifuna kuti zinyalala zitatuzi zikonzedwe.
3. Ili ndi luso lapamwamba la makina. Kutengera ndi kusintha kwa muyeso wa kutentha ndi kulondola kwa kuwongolera, kuyenda kwa zinthu zogwirira ntchito, kusintha kwa mpweya, kusintha kwa mphamvu, ndi zina zotero, zonse zitha kukonzedwa pasadakhale ndikukhazikitsidwa, ndipo kuzimitsa ndi kutenthetsa kumatha kuchitika pang'onopang'ono.
4. Mphamvu zomwe zimagwiritsidwa ntchito ndi zochepa kwambiri kuposa za uvuni wa bafa wamchere. Chipinda chotenthetsera chamakono cha graphite chili ndi makoma oteteza kutentha ndi zotchingira zopangidwa ndi zipangizo zapamwamba kwambiri zotetezera kutentha, zomwe zimatha kuyika mphamvu yotenthetsera yamagetsi mkati mwa chipinda chotenthetsera, zomwe zimapangitsa kuti mphamvuyo isungike bwino.
5. Kulondola kwa kuyeza ndi kuyang'anira kutentha kwa uvuni kwawonjezeka kwambiri. Mtengo wosonyeza kuti thermocouple ndi yofanana ndi kutentha kwa uvuni.1.5°c. Komabe, kusiyana kwa kutentha pakati pa zigawo zosiyanasiyana za zida zambiri zogwirira ntchito mu uvuni ndi kwakukulu. Ngati mpweya wochepa ukuyenda mokakamizidwa, kusiyana kwa kutentha kumatha kulamulidwa mkati mwa ±5°c.
Kuchotsa gasi ndi vuto la kusungunuka pang'onopang'ono kwa zinthu mu chotenthetsera cha graphite ndipo ndilo vuto lalikulu kwambiri pakugwira ntchito kwa chotenthetsera cha graphite. Magawo a mamolekyu omwe amapangidwa ndi kusonkhanitsa kwa mpweya ndi zakumwa amatha kumamatira pamwamba pa chinthu chilichonse cholimba. Chifukwa cha kuchepa pang'onopang'ono kwa mphamvu, magawo a mamolekyu awa amasungunuka pang'onopang'ono chifukwa mphamvu ya pamwamba pa izi ndi yocheperako kuposa yomwe imatulutsidwa ndi chotenthetsera cha graphite. Nayitrogeni, zosungunulira zosasunthika komanso mpweya wopanda mpweya zimakhala ndi liwiro lotulutsa gasi mwachangu. Mafuta ndi nthunzi yamadzi zidzapitiriza kumamatira pamwamba ndipo sizidzasungunuka mpaka maola angapo pambuyo pake. Zipangizo zokhala ndi mabowo, tinthu ta fumbi ndi zinthu zina zachilengedwe zidzawonjezera malo a pamwamba, kotero n'zotheka kuyambitsa kusungunuka kwambiri kwa gasi. Kuwala ndi kutentha kudzapereka mphamvu zokwanira kuti mamolekyu onyamulira atuluke pamwamba. Kutentha kwa ng'anjo kukakwera, kumatha kumasula mamolekyu omwe adamatira pamwamba pa kutentha kochepa. Chifukwa chake, kutentha kwa ng'anjo kukakwera, chochitika cha kusungunuka kwa gasi chidzawonjezeka pang'onopang'ono.
Kapangidwe kake, kuwongolera kutentha, njira yotenthetsera, ndi mlengalenga mkati mwa ng'anjo ya graphite heater zonse zidzakhudza mwachindunji mtundu wa chinthucho pambuyo pa kupanga graphite heater. Mu ng'anjo yotenthetsera yopangira, kukweza kutentha kwa chitsulo kungachepetse kukana kusungunuka, koma kutentha kwambiri kungayambitse kusungunuka kwa tirigu kapena kutentha kwambiri, zomwe zimakhudza kwambiri mtundu wa chinthucho mkati mwa graphite heater. Panthawi yokonza kutentha, ngati chitsulo chatenthedwa kufika pamalo ena pamwamba pa kutentha kofunikira kenako nkuzizira mwadzidzidzi ndi choziziritsira, kuuma ndi mphamvu ya chitsulocho zitha kuwonjezeka. Ngati chitsulocho chatenthedwa kufika pamalo ena pansi pa kutentha kofunikira kenako nkuzizira pang'onopang'ono, chingapangitse chitsulocho kukhala cholimba kwambiri.
Kuti mupeze zinthu zogwirira ntchito zokhala ndi malo osalala komanso miyeso yolondola, kapena kuchepetsa kukhuthala kwa chitsulo pofuna kuteteza nkhungu ndi kuchepetsa zololeza zopangira makina, ng'anjo zosiyanasiyana zotenthetsera zotsika ndi zosakhuthala zitha kugwiritsidwa ntchito. Mu ng'anjo yotenthetsera yotseguka yokhala ndi kukhuthala kochepa kapena kopanda kukhuthala, kuyaka kosakwanira kwa mafuta kumapanga mpweya wochepa. Kutenthetsa chinthu chogwirira ntchitocho kungachepetse kutayika kwa kutenthedwa kwa kukhuthala kufika pa 0.6%. Grafiti yoyera kwambiri imatanthauza ufa wa graphite wokhala ndi kaboni woposa 99.9%. Grafiti yoyera kwambiri iyi yokhala ndi kaboni wochuluka ili ndi mphamvu zamagetsi zabwino kwambiri, mphamvu zopaka mafuta, kukana kutentha kwambiri, kukana kutopa, ndi zina zotero. Grafiti yoyera kwambiri ili ndi pulasitiki wabwino ndipo imatha kusinthidwa kukhala zinthu zosiyanasiyana zoyendetsera magetsi, ndi zina zotero.
Graphite yoyera kwambiri imagwira ntchito yofunika kwambiri m'mafakitale opanga zinthu. Imagwiritsidwa ntchito m'mafakitale monga kuyendetsa magetsi, mafuta odzola, ndi zitsulo. Pakupanga graphite yoyera kwambiri, kuchuluka kwa zonyansa kuyenera kulamulidwa mosamala kuchokera kuzinthu zopangira, ndipo zinthu zopangira zokhala ndi phulusa lochepa ziyenera kusankhidwa. Kuphatikiza apo, kuyesetsa kuyenera kuchitidwa kuti tipewe kuwonjezera zonyansa momwe tingathere panthawi yopanga. Komabe, kuchepetsa zonyansa mpaka pamlingo wofunikira kumachitika makamaka mu njira yopangira graphitization. Graphitization imachitika kutentha kwambiri, ndipo ma oxide ambiri a zinthu zodetsedwa amawola ndi kusungunuka kutentha kwambiri. Kutentha kwa graphitization kukakwera, zinyalala zambiri zimatulutsidwa, ndipo kuyera kwa zinthu zopangidwa ndi graphite yoyera kwambiri kumawonjezeka. Kugwiritsa ntchito graphite yoyera kwambiri kumagwiritsa ntchito mphamvu zake zamagetsi zabwino kwambiri, mphamvu zopaka mafuta, kukana kutentha kwambiri, ndi zina zotero.
Chifukwa chomwe graphite yoyera kwambiri imakhala yoyera kwambiri komanso zodetsa zochepa zimadalira njira yabwino kwambiri yopangira ndi zida. Kuchuluka kwa zodetsa kuli kochepera 0.05%. Graphite yathu ya colloidal, nano-graphite, graphite yoyera kwambiri, ufa wa graphite wosalala kwambiri ndi ufa wina wa graphite zimagwiritsidwa ntchito kwambiri m'mafakitale a mankhwala, mafuta ndi mafuta odzola. Ufa wa graphite woyera kwambiri umagwiritsidwa ntchito pokonza ndi kupanga zinthu zotenthetsera zamagetsi, nkhungu zopangira zinthu, zitsulo zoyeretsera zoyera kwambiri, zitsulo zoyeretsera zoyera kwambiri, zinthu za semiconductor, ndi zina zotero.
