Iingenelo zeGlasi yeFiber kwiZixhobo zeKhemikhali eziSekelwe kwiGraphite

I-Graphite isetyenziswa kakhulu ekwenzeni izixhobo zeekhemikhali ngenxa yokumelana kwayo nokugqwala, ukuhanjiswa kombane, kunye nokuzinza kobushushu. Nangona kunjalo, i-graphite ineempawu ezibuthathaka zoomatshini, ingakumbi xa ichaphazeleka kwaye ingcangcazela.Ifayibha yeglasi, njengesixhobo esidityanisiweyo esisebenza kakuhle, sibonelela ngeenzuzo ezibalulekileyo xa sisetyenziswa kwizixhobo zeekhemikhali ezisekwe kwigrafiti ngenxa yokumelana nobushushu, ukumelana nokugqwala, kunye neempawu zayo zoomatshini eziphezulu. Iingenelo ezithile ziquka:

(1) Ukusebenza Okuphuculweyo KweeMechanical

Amandla okutsalwa kwefayibha yeglasi anokufikelela kwi-3,450 MPa, adlula kakhulu lawo egrafiti, adla ngokuba phakathi kwe-10 ukuya kwi-20 MPa. Ngokufaka ifayibha yeglasi kwizinto zegrafiti, ukusebenza ngokubanzi koomatshini kwezixhobo kunokuphuculwa kakhulu, kubandakanya ukumelana nempembelelo kunye nokungcangcazela.

(2) Ukumelana nokugqwala

I-glass fiber ibonakalisa ukumelana okuhle kakhulu nee-asidi ezininzi, ii-alkalis, kunye nezinyibilikisi. Nangona i-graphite ngokwayo ikwazi ukumelana nokugqwala kakhulu,ifayibha yeglasiinokubonelela ngokusebenza okuphezulu kwiindawo ezinobungozi beekhemikhali, ezifana neemeko zobushushu obuphezulu kunye noxinzelelo oluphezulu, imozulu ezikhupha ioksijini, okanye iindawo ze-hydrofluoric acid.

(3) Iipropati eziphuculweyo zobushushu

I-fiber yeglasi ine-coefficient ephantsi kakhulu yokwandiswa kobushushu (CTE) emalunga ne-5.0 × 10−7/°C, iqinisekisa uzinzo olulinganayo phantsi koxinzelelo lobushushu. Ukongeza, indawo yayo yokunyibilika ephezulu (1,400–1,600°C) inika ukumelana okubalaseleyo kobushushu obuphezulu. Ezi mpawu zivumela izixhobo zegrafiti eziqiniswe ngefayibha yeglasi ukuba zigcine ukuthembeka kwesakhiwo kunye nokusebenza kwiindawo ezinobushushu obuphezulu kunye nokuguquguquka okuncinci.

(4) Iingenelo zoBunzima

Ngobuninzi obumalunga ne-2.5 g/cm3, i-glass fiber inzima kancinci kune-graphite (2.1–2.3 g/cm3) kodwa ilula kakhulu kunezixhobo zesinyithi ezifana nentsimbi okanye i-aluminium. Ukudibanisa i-glass fiber kwizixhobo ze-graphite kuphucula ukusebenza ngaphandle kokunyusa ubunzima, okugcina i-lightweight yesixhobo kunye ne-portable.

(5) Ukonga iindleko

Xa kuthelekiswa nezinye izinto ezidityanisiweyo ezisebenza kakuhle (umz., i-carbon fiber), i-glass fiber ibiza kancinci, nto leyo eyenza ukuba ibe luncedo kwizicelo ezinkulu zoshishino:

Iindleko zezinto eziluhlaza:Ifayibha yeglasiikakhulu isebenzisa iglasi engabizi kakhulu, ngelixa i-carbon fiber ixhomekeke kwi-acrylonitrile ebiza kakhulu.

Iindleko Zokuvelisa: Zombini ezi zinto zifuna ukucutshungulwa kobushushu obuphezulu kunye noxinzelelo oluphezulu, kodwa ukuveliswa kwefayibha yekhabhoni kubandakanya amanyathelo anzima ongezelelweyo (umz., ukwenziwa kwepolymer, ukuzinzisa i-oxidation, ukwenziwa kwekhabhoni), okunyusa iindleko.

Ukuphinda Usebenzise Nokulahla: I-carbon fiber kunzima ukuyiphinda isetyenziswe kwaye ibeka iingozi kwindalo ukuba ayiphathwanga kakuhle, nto leyo ekhokelela kwiindleko eziphezulu zokuyilahla. I-glass fiber, ngokuchaseneyo, ilawuleka lula kwaye inobuhlobo nendalo kwiimeko zokuphela kobomi.
