Bayanin Samfura
Expandable graphite foda abu ne na graphite na musamman wanda aka yi masa magani. Lokacin da aka fallasa shi zuwa yanayin zafi mai girma, yana iya faɗaɗa da sauri don samar da tsutsotsin tsutsotsi mai ƙyalƙyali kamar tsari, yana ba da damar haɓakar ƙararsa don isa sau 100-400 na farkon girma. Ana amfani da shi sosai a fagage kamar rufewa, rigakafin gobara, jinkirin harshen wuta, da tallatawa.

Shiri na fadada graphite foda
(1) Zaɓin albarkatun ƙasa: Babban -mai inganci- graphite mai tsafta tare da tsaftar sama da 99%, wakilai masu tsaka-tsaki, da kuma abubuwan da ke haifar da iskar oxygen.
(2) Tsarin samarwa: Haɗin kai - Graphite yana haɗe tare da ma'auni masu tsaka-tsaki kuma ana jika shi cikin ruwan acid na musamman. An jiƙa cakuda a digiri 20-50 na mintuna 30-120 don ba da damar ƙwayoyin acid su shiga tsakanin yadudduka na graphite, suna samar da mahadi masu tsaka-tsaki na graphite.
(3) Wanke/bushewar ruwa: An cire ragowar acid ɗin, kuma an daidaita ƙimar pH zuwa 5-7 don gujewa lalatawar gaba. Ana yin bushewar ƙarancin zafin jiki a digiri 60-80 don hana haɓaka da wuri.
(4) Sieving: The karshe barbashi size ne sarrafawa zuwa 80-300 raga, wanda rinjayar da fadada rabo.
Ƙayyadaddun aikace-aikace na foda mai zazzagewa
(1) Wuta da harshen wuta{1} Ƙa'ida: Yana faɗaɗa a yanayin zafi mai zafi don samar da zafi{2}}insulating carbon Layer, ware oxygen. Aikace-aikace: Gine-ginen rufin wuta; harshen wuta na kebul -kaset na baya (mai maye gurbin halogen na al'ada{5}}madaidaitan harshen wuta); harshen wuta -maganin abubuwan da za a ƙara don polyurethane/epoxy resins (tare da ƙarin adadin 5-20%).
(2) Abubuwan Rubutun Riba: Bayan haɓakawa, yana cika micropores, haɓaka aikin rufewa. Aikace-aikace: Gasket don manyan flanges bututun zafin jiki{2}; Injin Silinda gaskets (yana ba su damar yin tsayayya da zafin jiki na digiri 1600).
(3) Abubuwan Adsorbent Halaye: Bayan fadadawa, yana da babban yanki na musamman kuma yana iya tallata tabo mai da ions ƙarfe mai nauyi.
Aikace-aikace: Maganin zubar da mai na ruwa; masana'antu tsaftace ruwan sharar gida.
(4) Sauran aikace-aikace Game da kayan baturi: Pre{1}}maganin faɗaɗawa ga batirin lithium anodes. Don canjin lokaci kayan ajiyar makamashi: Haɓaka haɓakar yanayin zafi. A cikin masana'antar soji: Yin hidima azaman matakan kariya na tsoma baki na lantarki{{4}.
Lura: 1. Sanya safar hannu, abin rufe fuska da tabarau don guje wa lamba/shakarwa; kurkura idan fata ta faru.
2.Keep daga zafi (fiye da digiri 80 na iya haifar da faɗaɗa da wuri) da buɗe wuta don hana splashing.
3. Yi aiki a wurin da ke da iska tare da cire ƙura don guje wa shaƙar ƙurar dogon lokaci.
4. Kada ku haɗu tare da oxidants / alkalis mai ƙarfi.
5. Adana an rufe shi a busasshen wuri; kauce wa karo, yawan zafin jiki da zafi yayin sufuri.
6. Zubar da sharar masana'antu; kar a watsar da gangan.
