Izinzuzo ze-Glass Fiber kumishini yamakhemikhali esekelwe ku-Graphite

I-Graphite isetshenziswa kabanzi ekukhiqizeni imishini yamakhemikhali ngenxa yokumelana kwayo nokugqwala okuhle kakhulu, ukuhanjiswa kukagesi, kanye nokuqina kokushisa. Kodwa-ke, i-graphite ibonisa izakhiwo ezibuthakathaka kakhulu zemishini, ikakhulukazi ngaphansi kwezimo zokushayisana nokudlidliza.I-fiber yengilazi, njengezinto ezihlanganisiwe ezisebenza kahle kakhulu, inikeza izinzuzo ezibalulekile uma isetshenziswa emishinini yamakhemikhali esekelwe ku-graphite ngenxa yokumelana kwayo nokushisa, ukumelana nokugqwala, kanye nezakhiwo zayo zemishini eziphakeme. Izinzuzo ezithile zifaka:

(1) Ukusebenza Okuthuthukisiwe Kwemishini

Amandla okuthamba kwefayibha yengilazi angafinyelela ku-3,450 MPa, adlula kakhulu amandla e-graphite, ngokuvamile asukela ku-10 kuya ku-20 MPa. Ngokufaka ifayibha yengilazi ezintweni ze-graphite, ukusebenza komshini jikelele kungathuthukiswa kakhulu, okuhlanganisa ukumelana nokushaywa kanye nokudlidliza.

(2) Ukumelana Nokugqwala

I-fiber yengilazi ikhombisa ukumelana okuhle kakhulu nama-asidi amaningi, ama-alkali, kanye nezinyibilikisi. Nakuba i-graphite ngokwayo imelana kakhulu nokugqwala,i-fiber yengilaziinganikeza ukusebenza okuphezulu ezindaweni eziyingozi kakhulu zamakhemikhali, njengezimo zokushisa okuphezulu kanye nezingcindezi eziphezulu, izimo ze-oxidizing, noma izindawo ze-hydrofluoric acid.

(3) Izakhiwo Ezithuthukisiwe Zokushisa

I-fiber yengilazi ine-coefficient ephansi kakhulu yokwanda kokushisa (i-CTE) engaba ngu-5.0 × 10−7/°C, okuqinisekisa ukuzinza kobukhulu ngaphansi kokucindezeleka kokushisa. Ngaphezu kwalokho, iphuzu layo lokuncibilika eliphezulu (1,400–1,600°C) linikeza ukumelana okuvelele kokushisa okuphezulu. Lezi zici zivumela imishini ye-graphite eqiniswe yi-fiber yengilazi ukuthi igcine ubuqotho besakhiwo kanye nokusebenza ezindaweni ezishisa kakhulu ngokuguquguquka okuncane.

(4) Izinzuzo Zesisindo

Njengoba inobuningi obungu-2.5 g/cm3, i-fiber yengilazi inzima kancane kune-graphite (2.1–2.3g/cm3) kodwa ilula kakhulu kunezinto zensimbi ezifana nensimbi noma i-aluminium. Ukuhlanganisa i-fiber yengilazi emishinini ye-graphite kuthuthukisa ukusebenza ngaphandle kokukhulisa isisindo kakhulu, okulondoloza isimo semishini esilula nesiphathekayo.

(5) Ukusetshenziswa Kahle Kwezindleko

Uma kuqhathaniswa nezinye izinto ezihlanganisiwe ezisebenza kahle kakhulu (isb., i-carbon fiber), i-glass fiber ishibhile kakhulu, okwenza ibe nenzuzo ezisetshenziswa ezimbonini ezinkulu:

Izindleko Zezinto Zokusetshenziswa:I-fiber yengilaziikakhulukazi isebenzisa ingilazi engabizi kakhulu, kanti i-carbon fiber incike ku-acrylonitrile ebizayo.

Izindleko Zokukhiqiza: Zombili izinto zidinga ukucutshungulwa okushisa okuphezulu kanye nokucindezela okuphezulu, kodwa ukukhiqizwa kwe-carbon fiber kuhilela izinyathelo ezengeziwe eziyinkimbinkimbi (isb., i-polymerization, ukuqina kwe-oxidation, i-carbonization), okunyusa izindleko.

Ukuvuselela Nokulahla: I-carbon fiber kunzima ukuyivuselela futhi ibeka izingozi zemvelo uma iphathwa kabi, okuholela ezindleleni eziphakeme zokulahla. I-glass fiber, ngokuphambene nalokho, ilawuleka kalula futhi inobungani nemvelo ezimweni zokuphela kwempilo.
