Ifayibha yeglasi inokohlulwa ibe yintsinga eqhubekayo, ifayibha yobude obusisigxina kunye noboya beglasi ngokwemilo nobude bayo.Ngokokwakheka kweglasi, inokwahlulwa ibe yi-alkali-free, i-chemical-resistant, i-alkali ephezulu, i-alkali ephakathi, amandla aphezulu, i-modulus ephezulu ye-elastic kunye ne-alkali-resistant (i-alkali-resistant) yeglasi imicu.
Izinto eziphambili zokuvelisa i-glass fiber yisanti ye-quartz, i-alumina kunye ne-pyrophyllite, i-limestone, i-dolomite, i-boric acid, i-soda ash, i-mirabilite kunye ne-fluorite.Iindlela zokuvelisa zinokwahlulwa ngokweendidi ezimbini: enye kukwenza ngokuthe ngqo iglasi etyhidiweyo ibe yimicu;Enye yeyokuba iglasi etyhidiweyo yenziwe kwiibhola zeglasi okanye iintonga ezinobubanzi obuyi-20mm, emva koko ifudunyezwe kwaye inyibilike ngeendlela ezahlukeneyo ukwenza imicu emihle kakhulu enobubanzi obuyi-3 ~ 80 μ m.Ifayibha yobude obungenasiphelo eyenziwe ngumzobo womatshini wendlela yesikweri ngeplatinum ialloy plate ibizwa ngokuba yifiber yeglasi eqhubekayo, eyaziwa ngokuba yifiber ende.Iintsinga ezingapheliyo ezenziwe nge-roller okanye ukuhamba komoya zibizwa ngokuba yimicu yeglasi esisigxina, eyaziwa ngokuba yimicu emifutshane.
Ifayibha yeglasi yohlulwe ngokwamabakala ahlukeneyo ngokubunjwa kwayo, iipropati kunye nokusetyenziswa kwayo.Ngokwebakala eliqhelekileyo (jonga itafile), i-fiber yeglasi ye-E-grade yeyona isetyenziswa kakhulu kwaye isetyenziswa ngokubanzi kwizinto zokufakelwa kombane.Iklasi s yifayibha ekhethekileyo.
Iglasi esetyenziselwa ukucola ifayibha yeglasi ukuvelisa ifayibha yeglasi yahlukile kwezinye iimveliso zeglasi.Amacandelo eglasi yeentsinga ezithe zathengiswa kumazwe ngamazwe zezi zilandelayo:
E-iglasi
Ikwaziwa njengeglasi engena-alkali, yiglasi ye-borosilicate.Okwangoku, yeyona fibre yeglasi esetyenziswa kakhulu, ene-insulation elungileyo yombane kunye neempawu zoomatshini.Isetyenziswa ngokubanzi kwimveliso yefiber yeglasi yokugquma umbane kunye nefayibha yeglasi kwifiber yeglasi eyomeleziweyo yeplastiki.Ukungalungi kwayo kukuba kulula ukugqweswa yi-acids ye-inorganic, ngoko ayifanelekanga kwindawo ye-asidi.
C-iglasi
Intonga yeglasi yeglasi, ekwabizwa ngokuba yiglasi yealkali ephakathi, iphawulwa ngokumelana ngcono neekhemikhali, ngakumbi ukuxhathisa kweasidi, kuneglasi engena-alkali, kodwa ukusebenza kwayo kombane kumbi, kwaye amandla ayo omatshini angaphantsi nge-10% ~ 20% ngaphantsi kwaleyo ye-alkali. i-alkali-free glass fiber.Ngokuqhelekileyo, ifayibha yeglasi yealkali yangaphandle iqulethe isixa esithile se-boron trioxide, ngelixa i-China i-medium-alkali fiber fiber ayinayo i-boron kwaphela.Kumazwe angaphandle, ifayibha yeglasi yealkali ephakathi isetyenziselwa kuphela ukuvelisa iimveliso zeglasi ezinganyangekiyo, ezinje ngeglasi yomphezulu wefiber, kwaye ikwasetyenziselwa ukomeleza izixhobo zokufulela i-asphalt.Noko ke, e China, medium-alkali iglasi ifayibha akhawunti ngaphezu kwesiqingatha (60%) imveliso iglasi ifayibha, kwaye isetyenziswa ngokubanzi ekomelezeni iglasi ifayibha eyomeleziweyo yeplastiki kunye nokuveliswa amalaphu okucoca kunye amalaphu esongwayo, kuba ixabiso layo yi. isezantsi kune-alkali-free glass fiber kwaye inokhuphiswano olomeleleyo.
amandla aphezulu eglasi fiber
Ibonakaliswa ngamandla aphezulu kunye nemodyuli ephezulu.Amandla ayo okuqina kwefayibha enye yi-2800MPa, emalunga ne-25% ephezulu kunaleyo ye-alkali-free glass fiber, kunye ne-elastic modulus yayo yi-86000MPa, engaphezulu kunaleyo ye-E-glass fiber.Iimveliso ze-FRP eziveliswe kunye nazo zisetyenziswa kakhulu kwishishini lomkhosi, indawo, izixhobo ze-bulletproof kunye nezixhobo zemidlalo.Nangona kunjalo, ngenxa yexabiso eliphezulu, ayinakuchazwa ngokusetyenziswa koluntu ngoku, kwaye imveliso yehlabathi malunga neetoni ezininzi.
Ifayibha yeglasi yeAR
Ikwaziwa njenge-alkali-resistant glass fiber, i-alkali-resistant glass fiber is the rib material of glass fiber reinforced (samente) concrete (GRC for short), eyi-100% ifayibha ye-inorganic kunye nendawo efanelekileyo yentsimbi kunye neasbestos kwi-non-load. -ukuthwala amacandelo esamente.I-alkali-resistant glass fiber ibonakaliswe ngokuxhathisa okulungileyo kwealkali, ukuxhathisa okusebenzayo kwi-corrosion yezinto eziphezulu zealkali kwisamente, ukubamba okuqinileyo, imodyuli ephezulu kakhulu, ukuchasana nempembelelo, amandla okuxinana kunye nokugoba, ukungakwazi ukuvutha, ukuxhathisa iqabaka, ubushushu kunye Ukumelana nokutshintsha kokufuma, ukumelana nokuqhekeka okugqwesileyo kunye nokunganyibiliki, ukuyila okuqinileyo kunye nokubumba okulula.I-alkali-resistant glass fibers luhlobo olutsha olusetyenziswa ngokubanzi kwi-high-performance reinforced (samente) ikhonkrithi.
Iglasi
Ikwaziwa njengeglasi ephezulu yealkali, yiglasi ye-sodium silicate eqhelekileyo, engafane isetyenziswe ukuvelisa ifayibha yeglasi ngenxa yokunganyangeki kwayo emanzini.
Iglasi ye-E-CR
Yiglasi ephuculweyo ye-boron-free kunye ne-alkali-free, esetyenziselwa ukuvelisa i-fiber yeglasi kunye nokuxhathisa okulungileyo kwe-asidi kunye nokuxhathisa kwamanzi.Ukumelana kwayo namanzi kumaxesha angama-7-8 angcono kunefayibha yeglasi engena-alkali, kwaye ukuxhathisa kwayo ngeasidi kungcono kakhulu kunoko kwefiber yeglasi yealkali ephakathi.Ludidi olutsha oluphuhliswe ngokukodwa kwimibhobho engaphantsi komhlaba kunye neetanki zokugcina.
D iglasi
Ikwaziwa njengeglasi yedielectric ephantsi, isetyenziselwa ukuvelisa ifayibha yeglasi ephantsi yedielectric enamandla alungileyo edielectric.
Ukongeza kule nxalenye yefiber yeglasi engasentla, kuye kwavela i-alkali-free glass fiber, engenayo i-boron kwaphela, ngaloo ndlela inciphisa ukungcoliseka kwendalo, kodwa ukugqunywa kombane kunye neempawu zomatshini ziyafana nezo ze-E-glass yendabuko.Ukongeza, kukho uhlobo lwefiber yeglasi enamalungu eglasi ephindwe kabini, esetyenziselwe ukuveliswa koboya beglasi, kwaye kuthiwa inamandla njenge-FRP yokuqinisa.Ukongeza, kukho ifayibha yeglasi engena-fluorine, eyifiber ephuculweyo yeglasi engena-alkali eyenzelwe iimfuno zokhuseleko lokusingqongileyo.
Ukuchonga ifayibha yeglasi yealkali ephezulu
Indlela elula yokuhlola ukubilisa i-fiber emanzini abilayo kwiiyure ezingama-6-7.Ukuba iphezulu ityuwa yealkali yeglauber, emva kwamanzi abilayo, ifayibha ekwi-warp kunye ne-weft directions iya kuba
Yonke imilinganiselo ikhululekile.
Ngokwemigangatho eyahlukeneyo, kukho iindlela ezininzi zokwahlula iifayili zeglasi, ngokubanzi ukusuka kwimibono yobude kunye nobubanzi, ukubunjwa kunye nokusebenza.
