Imiterere n'imikoreshereze ya grafiti

Ibisobanuro by'ibicuruzwa: grafiti

Ifu ya grafiti ni yoroshye, imvi yirabura, irimo amavuta menshi kandi ishobora kwanduza impapuro. Ubukana bwayo ni 1-2, kandi igera kuri 3-5 iyo imyanda yiyongera mu cyerekezo gihagaze. Uburemere bwihariye ni 1.9-2.3. Mu gihe cyo kwitandukanya kwa ogisijeni, aho ishongesha iri hejuru ya 3000 ℃, ikaba ari imwe mu myunyu ngugu irwanya ubushyuhe bwinshi. Mu bushyuhe bw'icyumba, imiterere y'ibinyabutabire bya grafiti irahamye, ntishongera mu mazi, iragabanuka, iragabanuka alkali n'ibintu bisukura; ibikoresho bifite ubushyuhe bwinshi kandi birwanya imikorere y'amashanyarazi, kandi bishobora gukoreshwa nk'ibikoresho birwanya imikorere y'amashanyarazi, birwanya kwangirika no gusiga amavuta.

Bitewe n'imiterere yayo yihariye, grafiti ifite ibi bikurikira: 1. Ubudahangarwa bw'ubushyuhe bwinshi: aho graphite ishonga ni 3850 ± 50 ℃, naho aho ishyuha ni 4250 ℃. Ni ukuvuga ko igipimo cyo kugabanya ibiro n'ingano y'ubushyuhe ni bike cyane iyo hakoreshejwe uburyo bwo gushyushya cyane, kandi imbaraga za grafiti ziyongera uko ubushyuhe bwiyongera. Kuri 2000 ℃, imbaraga za grafiti zikuba kabiri. 2. Ubushyuhe: ubushyuhe bwa grafiti buterwa n'ingano ya grafiti. Uko igipimo ari kinini, ni ko ingano y'ubushyuhe iba nto, kandi imikorere yo gusya iba myiza. 3. Ubuziranenge bw'imiti: grafiti ifite ubuziranenge bwiza bw'imiti mu bushyuhe bw'icyumba, irwanya aside, alkali na organic solvent corrugation. 4. Ubuziranenge bw'imiti: grafiti ifite ubukomere bwiza kandi ishobora gukandagirwa mu mpapuro nto. 5. Ubushyuhe burwanya: iyo grafiti ikoreshejwe mu bushyuhe bw'icyumba, ishobora kwihanganira impinduka zikomeye z'ubushyuhe nta kwangirika. Iyo ubushyuhe buzamutse mu buryo butunguranye, ingano ya grafiti ntizahinduka cyane kandi nta cyuho kizaba kigaragara.

Ikoreshwa:

1. Nk'ibikoresho birwanya ubushyuhe: grafiti n'ibicuruzwa byayo bifite imiterere yo kudashyuha cyane no gukomera cyane. Bikoreshwa cyane cyane mu gukoraicyuma gikozwe muri grafitimu nganda zikora ibyuma, kandi zikunze gukoreshwa nk'ibikoresho birinda ibyuma binini n'ibikoresho byo mu itanura bikoreshwa mu byuma.

2. Nk'ibikoresho byo kwisiga bidashira: grafiti ikunze gukoreshwa nk'amavuta yo kwisiga mu nganda z'imashini. Amavuta yo kwisiga ubusanzwe ntabwo akwiriye gukoreshwa mu muvuduko mwinshi, ubushyuhe bwinshi n'umuvuduko mwinshi.

3. Graphite ifite ubushobozi bwo kudahinduka mu binyabutabire. Ikoreshwa cyane mu nganda zikora peteroli, hydrometallurgy, gukora aside-base, fibre zikoze mu nganda, gukora impapuro n'izindi nganda, ibyo bikaba bishobora kuzigama ibikoresho byinshi by'icyuma.

4. Graphite ishobora gukoreshwa nk'icyuma gisukura ikaramu, irangi n'icyuma gisukura. Nyuma yo gutunganya ibintu byihariye, graphite ishobora gukorwamo ibikoresho bitandukanye byihariye kugira ngo bikoreshwe n'amashami y'inganda abishinzwe.
