Ifayibha yeglasi ineempawu ezibalaseleyo kwaye isetyenziswa kakhulu kwiinkalo ezininzi.Yimathiriyeli ye-inorganic non-metallic enokutshintsha isinyithi.Ngenxa yethemba lophuhliso oluhle, iinkampani ezinkulu zegilasi zefiber zigxile kuphando ekusebenzeni okuphezulu kunye nenkqubo yokuphucula ifayibha yeglasi.

Umnatha weFiberglass

1 Inkcazo yefiber yeglasi
Ifayibha yeglasi luhlobo lwemathiriyeli engeyiyo eyentsimbi enokuthi ithathe indawo yentsimbi kwaye inomsebenzi ogqwesileyo.Ilungiswa ngokuzoba iglasi etyhidiweyo kwimicu ngokusebenzisa amandla angaphandle.Ineempawu zamandla aphezulu, imodyuli ephezulu kunye nobude obuphantsi.Ukumelana nobushushu kunye noxinzelelo, i-coefficient enkulu yokwandisa i-thermal, indawo ephezulu yokunyibilika, ubushushu bayo obuthambileyo bunokufikelela kwi-550 ~ 750 ℃, ukuzinza okuhle kweekhemikhali, akukho lula ukutshisa, kuneempawu ezithile ezigqwesileyo ezifana nokuxhathisa umhlwa, kwaye isetyenziswe ngokubanzi kwiindawo ezininzi. .
 
2 Iimpawu zefiber yeglasi
Indawo yokunyibilika yefiber yeglasi yi-680℃, indawo yokubilisa yi-1000℃, kwaye ukuxinana yi-2.4～2.7g/cm3.Amandla e-tensile yi-6.3 ukuya kwi-6.9 g / d kwisimo esiqhelekileyo kunye ne-5.4 ukuya kwi-5.8 g / d kwindawo emanzi.Ifiber yeglasi inokumelana nokushisa okulungileyo kwaye yinto ephezulu yokukhusela i-insulating kunye ne-insulation efanelekileyo, efanelekileyo ukuveliswa kwe-thermal insulation kunye nezixhobo zomlilo.
 
3 Ukuqulunqwa kwefiber yeglasi
Iglasi esetyenziswa ekuveliseni imicu yeglasi yahlukile kwiglasi esetyenziswa kwezinye iimveliso zeglasi.Iglasi esetyenziswa kwimveliso yeentsinga zeglasi iqulethe la macandelo alandelayo:
(1)Iglasi ye-E,ekwabizwa ngokuba yiglasi engena-alkali, yeyeglasi ye-borosilicate.Phakathi kwezinto ezisetyenziswayo ngoku kwimveliso yeglasi, iglasi engena alkali yeyona isetyenziswa kakhulu.Iglasi engenaalkali inogqume kakuhle kunye neempawu zoomatshini, kwaye isetyenziswa ikakhulu ukuvelisa imicu yeglasi ekhuselayo kunye nemicu yeglasi ephezulu, kodwa iglasi engena alkali ayixhathisi kwi-corrosion ye-asidi ye-inorganic, ngoko ayifanelekanga ukusetyenziswa kwindawo ezineasidi. .Sine-e-glassukuzulazula kwefiberglass, i-e-glassfiberglass elukiweyo ukujikeleza,kunye ne-e-glassi-fibeglass mat.
 
(2)C-iglasi, ekwaziwa njengeglasi yealkali ephakathi.Xa kuthelekiswa neglasi engena-alkali, inokumelana neekhemikhali ezingcono kunye neempawu ezimbi zombane kunye nezoomatshini.Ukongeza i-diboron trichloride kwiglasi ye-alkali ephakathi inokuvelisaiglasi ifayibha umphezulu mat,eneempawu zokumelana nomhlwa.Iintsinga zeglasi ye-Boron-free medium-alkali isetyenziswa ikakhulu kwimveliso yamalaphu okucoca kunye namalaphu okusonga.

I-Fiberglass inqunyulwe i-strand mat

(3)Ifiber yeglasi ephezulu,njengoko igama libonisa, i-fiber yeglasi ephezulu yamandla ineempawu zamandla aphezulu kunye ne-modulus ephezulu.Amandla ayo e-fiber tensile yi-2800MPa, emalunga ne-25% ephezulu kunaleyo ye-alkali-free glass fiber, kunye ne-elastic modulus yayo yi-86000MPa, engaphezulu kune-E-glass fiber.Imveliso yefiber yeglasi ephezulu yamandla ayiphezulu, idityaniswa namandla ayo aphezulu kunye nemodyuli ephezulu, ke isetyenziswa ngokubanzi kumkhosi, kwinqwelomoya kunye nezixhobo zemidlalo kunye namanye amacandelo, kwaye ayisetyenziswa kakhulu kwezinye iindawo.
 
(4)Ifayibha yeglasi yeAR, ekwaziwa njenge-alkali-resistant glass fiber, yi-inorganic fiber.I-alkali-resistant glass fiber ine-alkali yokumelana ne-alkali kwaye inokuxhathisa ukubola kwezinto eziphezulu zealkali.Inemodyuli enwebekayo ephezulu kakhulu kunye nokuchasana kwempembelelo, amandla okuqina kunye namandla okugoba.Ikwanazo neempawu zokungatsha, ukuxhathisa iqabaka, ubushushu kunye nokumelana nokufuma, ukumelana nokuqhekeka, ukungagungqi, ukuqina kweplastiki kunye nokubumba okulula.Umbambo imathiriyeli yeglasi ifayibha ikhonkrithi eyomeleziweyo.
 
4 Ukulungiswa kweefiber zeglasi
Inkqubo yokwenziwa kweifayibha yeglasikukuqala ukunyibilikisa izinto ekrwada, kwaye emva koko yenze unyango lwefiberizing.Ukuba kuya kwenziwa kwimilo yeebhola zeglasi zefiber okanye ii-fiberglass rods, unyango lwe-fiberizing alunakwenziwa ngokuthe ngqo.Kukho iinkqubo ezintathu zefibrillation kwiifiber zeglasi:
Indlela yokuzoba: eyona ndlela iphambili yindlela yokuzoba i-filament nozzle, ilandelwa yindlela yokudweba intonga yeglasi kunye nendlela yokudweba i-melt drop drop;
Indlela ye-Centrifugal: i-drum centrifugation, i-step centrifugation kunye ne-horizontal porcelain disc centrifugation;
Indlela yokuvuthela: indlela yokuvuthela kunye nendlela yokuvuthela ngomlomo.
Ezi nkqubo zininzi zingentla zinokusetyenziswa ngokudityaniswayo, njengokuzoba-ukuvuthela njalo njalo.I-post-processing iyenzeka emva kwe-fiberizing.Ukusetyenzwa kwangemva kokusetyenzwa kwemicu yeglasi yelaphu kwahlulwe ngokwala manyathelo mabini alandelayo:
(1) Ngexesha lokwenziwa kweentsinga zeglasi, imicu yeglasi edityanisiweyo phambi kokujijwa kufuneka ilinganiswe, kwaye iintsinga ezimfutshane kufuneka zitshizwe ngesithambiso phambi kokuba ziqokelelwe kwaye zidutywe ngemingxuma.
(2) Ukuqhubela phambili, ngokwemeko yefiber yeglasi emfutshane kunye nefutshanei-fiber yeglasi yokujikeleza kukho la manyathelo alandelayo:
①Amanyathelo okulungisa ifayibha yeglasi emfutshane:
②Ukusetyenzwa kwamanyathelo eglasi ye-fiber roving:
