Common tsarkakewa hanyoyin na flake graphite da abũbuwan amfãni da rashin amfani

Fassarar graphiteAna amfani da shi sosai a masana'antu, amma buƙatar graphite flake ya bambanta a masana'antu daban-daban, don haka graphite flake yana buƙatar hanyoyin tsarkakewa daban-daban. Editan graphite mai zuwa na Furuite zai bayyana menene hanyoyin tsarkakewaflake graphiteyana da:

1. Hydrofluoric acid Hanyar.
Babban abũbuwan amfãni daga hydrofluoric acid Hanyar ne high datti cire yadda ya dace, high sa na kayayyakin, kadan tasiri a kan yi na graphite kayayyakin da low makamashi amfani. Rashin hasara shi ne cewa hydrofluoric acid yana da guba sosai kuma yana lalata, kuma dole ne a dauki tsauraran matakan kariya a cikin tsarin samar da kayan aiki.Maƙasudin buƙatun kayan aiki kuma yana haifar da karuwar farashi. Bugu da ƙari, ruwan datti da hanyar hydrofluoric acid ke samarwa yana da guba sosai kuma yana lalata, kuma yana buƙatar kulawa mai tsanani kafin a iya fitar da shi. Saka hannun jari a cikin kariyar muhalli kuma yana rage fa'idodin ƙarancin kuɗi na hanyar hydrofluoric acid.
2, Hanyar tsaftace acid ta asali.
Abubuwan da ke cikin carbon na graphite da aka tsarkake ta hanyar alkaline acid na iya kaiwa sama da 99%, wanda ke da halayen ƙarancin saka hannun jari na lokaci ɗaya, ƙimar samfur mai girma da daidaita tsarin aiki mai ƙarfi. Bugu da ƙari, yana da abũbuwan amfãni daga na yau da kullum kayan aiki da kuma karfi versatility. Hanyar acid ta asali ita ce hanyar da aka fi amfani da ita a kasar Sin. Rashinsa shine babban amfani da makamashi, dogon lokacin amsawa, babban asarar graphite da mummunar gurɓataccen ruwan sha.
3. Hanyar gasasshen chlorination.
Ƙananan zafin zafi da ƙananan chlorine amfani da hanyar gasasshen chlorination yana rage farashin samarwagraphite. A lokaci guda, abun cikin carbon na samfuran graphite daidai yake da na maganin hydrofluoric acid, kuma adadin dawo da hanyar gasa chlorination ya fi girma. Duk da haka, saboda chlorine mai guba ne kuma mai lalata, yana buƙatar aiki na kayan aiki mai yawa kuma yana buƙatar ɗaukar hankali sosai, kuma gas ɗin wutsiya dole ne a kula da shi yadda ya kamata, don haka zuwa wani lokaci, yana iyakance yaduwarsa da aikace-aikace.
4. Hanyar zafi mai girma.
Babban fa'idar hanyar yanayin zafin jiki shine cewa abun ciki na carbon na samfurin yana da girma sosai, wanda zai iya kaiwa sama da 99.995%. Rashin hasara shi ne cewa dole ne a tsara ma'aunin zafin jiki na musamman da kuma gina shi, kayan aiki yana da tsada, kuma akwai zuba jari na biyu da yawa. Bugu da ƙari, yawan amfani da makamashi yana da yawa, kuma yawan kuɗin wutar lantarki yana ƙara yawan farashin samarwa. Haka kuma, matsananciyar yanayin samarwa kuma yana sanya iyakar aikace-aikacen wannan hanyar ta iyakance. Sai kawai a cikin tsaron ƙasa, sararin samaniya da sauran lokatai tare da buƙatu na musamman akan tsabtar samfuran graphite, ana ɗaukar wannan hanyar don samar da ƙaramin tsari.graphite, kuma ba za a iya yada shi a masana'antu ba.
