Urebye kuri karubone, kuki igiciro cya fibre karubone kiri hejuru?

Imikorere ihanitse yibikoresho bya karubone ituma igira imikorere ihanitse cyane mubikorwa byinshi.Iyofibreibicuruzwa bikoreshwa, usanga igiciro rusange ari kinini.Ahantu igiciro cyibicuruzwa byavunitse biri hejuru bifite aho bihuriye nahantu henshi.Ikipe yacu izakubwira duhereye kuri fibre fibre.

Ibicuruzwa bya fibre ya karubone tubona mubyukuri bitandukanye cyane nibikoresho bya fibre fibre, kubera ko fibre idashobora gukorwa wenyine, kandi igomba guhuzwa na resin matrix kugirango irangize umusaruro wibicuruzwa.Imwe mumpamvu zituma igiciro cyibicuruzwa bya fibre gihenze cyane ni uko igiciro cya firimu ya karubone kiri hejuru cyane, bityo rero tugomba kubanza gusobanukirwa nibikoresho bikurura fibre.

Hariho ubwoko butatu bwa fibre yamenetse, harimo polyacrylonitrile (PAN) ishingiye kuri fibre ya karubone, fibre ishingiye kuri karuboni fibre na karuboni fibre.Ibisanzwe bya PAN bishingiye kuri karubone mubyukuri nibyo bisanzwe, kandi umugabane wose wisoko urenga 90%, kubwibyo fibre ya karubone ya termoplastique isanzwe yerekeza kuri PAN ishingiye kuri karuboni.

Polyacrylonitrile nayo yahimbwe mugitangira.Yahimbwe na Akio Kondo mu Buyapani mu 1959, hanyuma ikorerwa cyane muri Toray mu 1970. Filime ya karubone yose ya polyacrylonitrile ifite imbaraga nyinshi cyane n'ibiranga inyenyeri ntangarugero.Fibre ishingiye kuri asfalt yakozwe na kaminuza ya Gunma yo mu Buyapani mu 1965. Iyi fibre fibre karubone ifite ubushyuhe bwinshi cyane bwa 90OGPa, bityo ikoreshwa cyane mubikoresho byihariye bikora.Fibre ya karuboni ishingiye kuri Viscose yakoreshejwe cyane nkibikoresho bigize ibikoresho byo mu kirere byo mu kirere mu myaka ya za 1950, kandi ni ibikoresho bizakoreshwa ubu.Twasanze rero bibiri bya mbere byavumbuwe nabayapani, niyo mpamvu igipimo cyo gupima imikorere ya fibre fibre ikurura ishingiye kuri Toray carbone fibre.

Birumvikana ko ubushakashatsi niterambere ryibikoresho bya karuboni fibre preursors byakomeje gutera imbere mumyaka yashize, ariko ingaruka rusange ntiratangira gukurikizwa.Muri iki gihe, ishingiye kuri PAN iracyari ishingiro.Mu musaruro wa feri ya karubone, umusaruro wa karubone wibice bitatu byabanjirije ushobora kugera kuri B80%.Mubyukuri, igiciro cyibintu bya karuboni fibre filaments byanze bikunze bizaba biri hasi, ariko umusaruro wibibanza bigomba gukosorwa no guhindurwa.Iyi nzira izamura cyane ibiciro byumusaruro kandi igabanye umusaruro kugeza 30%.Ibishingiye kuri PAN rero biracyakunzwe cyane.

Reka rero turebe kuri fibre ya karubone ikoreshwa cyane.Igiciro cya fibre ya karubone ishingiye kuri PAN iri hasi cyane ugereranije na asibalt ishingiye kuri karubone, kandi irashobora gukoreshwa mubice byinshi.Igiciro cya fibre ishingiye kuri PAN kuri satelite iri hejuru ya 200 yen / kg, mugihe igiciro cya fibre karubone kumodoka kiri munsi ya 2000 yen / kg.

Noneho turacyakoresha ibikoresho bya karuboni ya Toray nkibishingiro.Hano, PAN ishingiye kuri fibre yamenetse igabanijwemo imirongo minini kandi nto.Kurugero, igiciro cya 3K isanzwe ni 50-70 US $ / kg, naho 6K ni 4-50 US $ / kg.Kubwibyo, turashobora kandi gusobanukirwa impamvu imirongo mito ikoreshwa cyane murwego rwo hejuru.

Kubwibyo, tuvuga ko igiciro cya fibre fibre izaba ihenze cyane.Ntabwo nta mpamvu ifite byinshi byo gukora nibikoresho fatizo.Byongeye kandi, igiciro cyibicuruzwa bya fibre karubone biri hejuru cyane, kandi bifite byinshi bifitanye isano nuko ibicuruzwa bya fibre fibre bisaba akazi nibikoresho byinshi.
