Ifayibha yeglasi ineempawu ezintle kakhulu kwaye isetyenziswa kakhulu kwiindawo ezininzi. Yinto engeyoyasemethini engaphiliyo enokuthatha indawo yesinyithi. Ngenxa yamathemba ayo ophuhliso amahle, iinkampani ezinkulu zefayibha yeglasi zigxile kuphando malunga nokusebenza okuphezulu kunye nokuphuculwa kwenkqubo yefayibha yeglasi.
1 Inkcazelo yefayibha yeglasi
Ifayibha yeglasi luhlobo lwezinto ezingezizo ezesinyithi ezingaphiliyo ezinokuthatha indawo yesinyithi kwaye zisebenza kakuhle kakhulu. Zilungiswa ngokutsala iglasi enyibilikisiweyo ibe yifayibha ngokusebenzisa amandla angaphandle. Zineempawu zamandla aphezulu, imodulus ephezulu kunye nobude obuphantsi. Ukumelana nobushushu kunye nokucinezeleka, i-coefficient enkulu yokwandisa ubushushu, indawo ephezulu yokunyibilika, ubushushu bayo bokuthambisa bunokufikelela kuma-550 ~ 750 ℃, uzinzo oluhle lweekhemikhali, akukho lula ukutsha, zineempawu ezithile ezintle ezifana nokumelana nokugqwala, kwaye zisetyenziswe kakhulu kwiindawo ezininzi.
Iimpawu ezi-2 zefayibha yeglasi
Iqondo lokunyibilika kwefayibha yeglasi yi-680℃, iqondo lokubila yi-1000℃, kwaye uxinano yi-2.4 ~ 2.7g / cm3. Amandla okutsalwa yi-6.3 ukuya kwi-6.9 g / d kwimeko eqhelekileyo kunye ne-5.4 ukuya kwi-5.8 g / d kwimeko emanzi.Ifayibha yeglasi inokumelana kakuhle nobushushu kwaye sisixhobo sokukhusela esikumgangatho ophezulu esine-insulation elungileyo, esifanelekileyo kwimveliso ye-thermal insulation kunye nezinto ezingatshiyo.
3 Ukwakheka kwefayibha yeglasi
Iglasi esetyenziswa ekuveliseni imicu yeglasi yahlukile kwiglasi esetyenziswa kwezinye iimveliso zeglasi. Iglasi esetyenziswa ekuveliseni imicu yeglasi inala macandelo alandelayo:
(1)Iglasi ye-elektroniki,eyaziwa ngokuba yiglasi engena-alkali, yeyeglasi ye-borosilicate. Phakathi kwezinto ezisetyenziswa ngoku ekuveliseni imicu yeglasi, iglasi engena-alkali yeyona isetyenziswa kakhulu. Iglasi engena-alkali ine-insulation elungileyo kunye neempawu zoomatshini, kwaye isetyenziselwa kakhulu ukuvelisa imicu yeglasi ekhuselayo kunye nemicu yeglasi enamandla aphezulu, kodwa iglasi engena-alkali ayimelani nokugqwala kwe-inorganic acid, ngoko ke ayifanelekanga ukusetyenziswa kwiindawo ezine-asidi. Sine-e-glassukuzulazula kwefiberglass, iglasi ye-elektronikiukuzulazula okulukiweyo kwefayibha，kunye neglasi ye-elektronikiimathi ye-fibegrlass.
(2)Iglasi ye-C, ekwaziwa ngokuba yiglasi ephakathi kwe-alkali. Xa ithelekiswa neglasi engena-alkali, inokumelana okungcono kweekhemikhali kunye neempawu ezimbi zombane kunye nezoomatshini. Ukongeza i-diboron trichloride kwiglasi ephakathi ye-alkali kunokuvelisaimathi yomphezulu wefayibha yeglasi,eneempawu zokumelana nokugqwala. Iifayibha zeglasi ze-alkali eziphakathi ezingenaboron zisetyenziswa kakhulu ekuveliseni amalaphu okucoca kunye namalaphu okusonga.
I-fiberglass eqoshiweyo yemicu
(3)Ifayibha yeglasi enamandla aphezulu,njengoko igama lisitsho, ifayibha yeglasi enamandla aphezulu ineempawu zokuba namandla aphezulu kunye nemodulus ephezulu. Amandla ayo okutsalwa kwefayibha yi-2800MPa, engaphezulu nge-25% kunefayibha yeglasi engena-alkali, kwaye imodulus yayo ethambileyo yi-86000MPa, ephezulu kunefayibha yeglasi ye-E. Imveliso yefayibha yeglasi enamandla aphezulu ayiphezulu, idibene namandla ayo aphezulu kunye nemodulus ephezulu, ngoko ke isetyenziswa ngokubanzi kwizixhobo zomkhosi, zeenqwelo moya kunye nezemidlalo nakwamanye amasimi, kwaye ayisetyenziswa kakhulu kwamanye amasimi.
(4)Ifayibha yeglasi ye-AR, eyaziwa ngokuba yi-fiber yeglasi enganyangekiyo kwi-alkali, yi-fiber engaphiliyo. I-fiber yeglasi enganyangekiyo kwi-alkali inokumelana okuhle kwe-alkali kwaye inokumelana nokugqwala kwezinto eziphezulu ze-alkali. Ine-modulus ephezulu kakhulu kunye nokumelana nempembelelo, amandla okutsalwa kunye namandla okugoba. Ikwanazo neempawu zokungatshi, ukumelana neqabaka, ukumelana nobushushu kunye nokufuma, ukumelana nokuqhekeka, ukungenwa kwamanzi, i-plasticity eqinileyo kunye nokubumba okulula. Izinto zembambo zekhonkrithi eqinisiweyo yefayibha yeglasi.
4 Ukulungiswa kweefayibha zeglasi
Inkqubo yokuvelisaifayibha yeglasiNgokwesiqhelo kufuneka kuqala kunyibilikiswe izinto ezikrwada, uze emva koko kwenziwe unyango lwe-fiberizing. Ukuba iza kwenziwa ibe ziibhola zefayibha zeglasi okanye iintambo ze-fiberglass, unyango lwe-fiberizing alunakwenziwa ngokuthe ngqo. Kukho iinkqubo ezintathu ze-fibrillation kwiifayibha zeglasi:
Indlela yokuzoba: indlela ephambili yindlela yokuzoba nge-filament nozzle, ilandelwe yindlela yokuzoba nge-glass rod kunye nendlela yokuzoba nge-melt drop;
Indlela ye-Centrifugal: i-drum centrifugation, i-step centrifugation kunye ne-horizontal porcelain disc centrifugation;
Indlela yokuvuthela: indlela yokuvuthela kunye nendlela yokuvuthela ngempumlo.
Ezi nkqubo zininzi zingasentla zingasetyenziswa ngokudibeneyo, njengokutsalwa kwemifanekiso njalo njalo. Ukulungiswa emva kokufakelwa ifayibha kwenzeka emva kokufakelwa ifayibha. Ukulungiswa emva kokufakelwa kwefayibha yeglasi yelaphu kwahlulwe ngokwamanyathelo amabini aphambili alandelayo:
(1) Ngexesha lokuveliswa kwemicu yeglasi, imicu yeglasi edityanisiweyo ngaphambi kokujijwa kufuneka ibe nobukhulu obufanayo, kwaye imicu emifutshane kufuneka itshizwe nge-lubricant ngaphambi kokuba iqokelelwe kwaye igqunywe ngemingxuma.
(2) Ukuqhubekeka kokucubungula, ngokwemeko yefayibha yeglasi emfutshane kunye nefayibha emfutshaneukuhambahamba ngefayibha yeglasi kukho la manyathelo alandelayo:
①Amanyathelo okulungisa ifayibha yeglasi emfutshane:
②Amanyathelo okucubungula ifayibha yeglasi esisiseko:
