1. Kuyambitsa kwa zojambulajambula zojambula
Ziphuphu zojambulandi zida zofunikira mu makampani ogulitsa zitsulo. Koma nchiyani chimawapangitsa iwo kukhala amtengo wapatali, ndipo chifukwa chiyani akatswiri opezeka amadalira graphite pazinthu zina? Zonse zimatsikira ku malo apadera a graphite: mawonekedwe owoneka bwino, kukana kwapadera, komanso kukhazikika kodabwitsa kwamankhwala.
Amagwiritsidwa ntchito kwambiri m'mafakitale ngati chitsulo choponya chitsulo, chofufumitsa chamtengo wapatali, ndipo maziko, opanduka, zojambulajambula zimadalirika kuti kutentha kwambiri ndi kuzimiririka kwambiri. Ndizofala kwambiri mu njira zomwe zimakhudza Propnanilu aluminium Fardieries kapena malo okwera kwambiri. Ziphuphu zojambula osati zongokumana ndi zinthu zozama koma zimawonetsetsa kuti kuipitsidwa kochepa, komwe ndikofunikira kwambiri kwa chitsulo chopota.
2. Kumvetsetsa kwa Graphite Kusungunuka ndi Kutentha Kwathunthu
2.1. Kutentha kwa graphite
Graphite ili ndi malo osungunuka kwambiri ozungulira 3,600 ° ° C (6,512 ° F). Kutentha kumeneku ndi kupitirira mfundo zosungunuka za zitsulo zomwe zimakonda kukonzedwa m'mawu, monga:
- Mtovu: 1,085 ° C (1,984 ° F)
- Chiwaya: 660 ° C (1,220 ° F)
- Chitsulo: 1,538 ° C (2,800 ° F)
Chifukwa cha izi, graphite ndi wangwiro pakugwiritsa ntchito komwe kutentha kumafunikira. Pomwe graphite simakhala ndikufika posintha malo osungunuka m'mayikidwe, kutentha kwake kwakukulu kumapangitsa kukhala wokhazikika komanso kulimba pakuwonekera kwa nthawi yayitali.
2.2. Kutentha kwa graphite
Zikopa zambiri zokopa kwambiri zimayikidwa kulumikizana ndi kutentha pakati pa 1,800 ° C mpaka 2,800 ° ° zowirira C kutengera ndi kapangidwe kake ndi kapangidwe kake. Kulimba kwa kutentha kwambiri kumeneku kumapangitsa graphite mphamvu yoyenera mapulogalamu osiyanasiyana, chifukwa cha zitsulo zosungunula, chifukwa cha zitsulo zosungunula monga mkuwa ndi ma aluminiyamu osokoneza bongo.
| Chitsulo | Malo osungunuka (° C) | Zida zolimbikitsidwa |
|---|---|---|
| Mtovu | 1,085 | Graphite, Silicon Carbide |
| Chiwaya | 660 | Graphite, dongo |
| Siliva | 961 | Gilaphite |
| Golidi | 1,064 | Gilaphite |
| Chitsulo | 1,370 - 1,520 | Graphite, Silicon Carbide |
Chidziwitso: Gawo ili limafotokoza momwe zida zojambulajambula zothandizira zimathandizira pakusintha kosiyanasiyana kwa zitsulo zosiyanasiyana.

Sikuti zopachikidwa zonse zimapangidwa zofanana. Umu ndi Graphite ikufanana ndi zida zina zotchuka:
- Kukonzanso simenti: Kudziwika chifukwa cha kulimba kwawo komanso kugwiritsa ntchito mtengo wake, luso lapakatikati la simenti limagwira bwino ntchito pogwiritsa ntchito kutentha pang'ono. Komabe, alibe kutentha kwambiri komanso kuwonjezeka kwa mafuta opangira graphite.
- Silika ndi Curamic Cuccibles: Izi zimagwiritsidwa ntchito kawirikawiri kwa ma valoys kapena ma labotale koma amakonda kukhala okhazikika pakugwiritsa ntchito mafakitale ambiri. Zimakhalanso zovuta kwambiri ndi kugwedezeka kwa mafuta, makamaka potentha mwachangu komanso kuzungulira kwa nyengo.
| Zinthu Zopachika | Kutentha kwa max (° C) | Ntchito Zabwino |
|---|---|---|
| Gilaphite | 1,800 - 2,800 | Kuponyera zitsulo zotentha kwambiri, zoyenga |
| Silicon Carbide | 1,650 - 2,200 | Zitsulo zosakhazikika, |
| Simenti yokonzanso simenti | 1,300 - 1,800 | Makina owonjezera kutentha |
| Silika | 1,600 - 1,800 | Malonda a Laborator ndi Mankhwala |
3.1. Chifukwa Chiyani Tiyenera Kusankha Graphite?
Chithunzi chopambana chomwe zinthu zina zimasokonekera. Kukana kwake kuvunda kwamankhwala, kuwonjezeka kwamafuta, komanso kuthekera kopikuza kutentha kwamafuta kumapangitsa kuti mafakitale ogulitsa azitsulo. Zitsulo zopanda graphite ndi zitsulo zosungunulira zimalepheretsanso kuipitsidwa, kuonetsetsa zinthu zapamwamba kwambiri.
4. Kusankha ufulu wopaka zitsulo
Kusankha chipamba cholondola kumafuna zambiri kuposa kungodziwa kuti pamakhala matenthedwe. Nazi zinthu zina zofunika kuziganizira:
- Kukula koyipa: Zikopa zojambula zimabwera mosiyanasiyana, kuchokera kumadera ang'onoang'ono a labotale ku mafakitale omwe amatha kukhala ndi ma kilogalamu a zitsulo. Kukula kovunda kumayenera kusankhidwa potengera kuchuluka kwa chitsulo chokonzedwa ndi mtundu wa ntchentche.
- Maonekedwe: Zingwe zimapezeka m'njira zingapo, monga cylindrical, zokhazikika, komanso pansi-mapangidwe opanga. Maonekedwe amakhudza kutsanulira kwamphamvu, kugawa kwamafuta, komanso kusamala pothana.
- Kutentha: Nthawi zonse zimatsimikizira kutentha kwapa zoopsa, makamaka pogwira ntchito ndi zitsulo zomwe zimafuna kutentha kwambiri, monga chitsulo ndi mkuwa.
| Mtundu wopachika | Zabwino kwambiri | Mau abwino |
|---|---|---|
| Kuzungulira | Kutulutsa Kwambiri | Ngakhale kugawa kutentha, |
| Zolumikizana | Kuthiranso | Kuthira mosavuta, kumachepetsa spaillage |
| Kutsanulira pansi | Mapulogalamu akuluakulu | Kuyenda bwino, kumachepetsa kuipitsidwa |
5. Opanga zojambulajambula ndi zomangamanga
Kusankha Wodalirikagraphite wopachikidwaWopanga ndi wofunikira kuti agwiritse ntchito bwino komanso kukhala ndi moyo wambiri. Nazi zina mwazofunikira kuti muyang'ane wopanga:
- Khalidwe labwino: Graphite wamkulu-oyera amatsimikizira kukana kwa kutentha, kuchepetsa kuvala, ndikuchepetsa zosayera.
- Kupanga: Njira zokakamiza zadongosolo zimachitika chifukwa champhamvu kwambiri.
- Zosankha: Opanga ena amapereka kukula kwa miyambo ndi mawonekedwe kuti afanane ndi zofunikira zamafakitale.
Kugwira ntchito ndi wopanga wodziwa zambiri samangotsimikizira kuti ndiolowera kuwongolera katswiri posankha wopatsirana woyenera pamapulogalamu enaake.
6. Kusamalira ndi kukonza zolimba za graphite
Chisamaliro choyenera chimafalikira ngati zopondera za graphite ndipo amawonetsetsa kugwira ntchito kosalekeza. Nayi malangizo ena okonza:
- Kufanana: Nthawi zonse preheat graphite yolimbana isanayambe kuyendetsa chinyezi chilichonse chotsalira komanso kupewa kusweka.
- Pewani kusintha kwa kutentha: Graphite imalimbana ndi kugwedezeka kwa mafuta, koma kutentha kwadzidzidzi kumatha kuwonongeka.
- Yeretsani pafupipafupi: Zotsalira zachitsulo zitha kuchitira ndi graphite, kuwononga mphamvu. Kuyeretsa pambuyo pakugwiritsa ntchito kumalepheretsa kumanga.
- Kusunga: Sungani zojambulajambula zojambula m'malo owuma kuti mupewe kuyamwa chinyezi, chomwe chingapangitse kugwedeza kwamatenthedwe.
Pambuyo pa zinthu izi zimathandizanso mosamalitsa kukhulupirika kwa zigawenga za zojambulajambula, kuchepetsa kufunika kwa zinthu zosintha.
7. Mafunso Omwe Amafunsidwa Kwambiri (FAQS)
