Ukwakheka kanye nezakhiwo ze-glass fiber

Ingilazi esetshenziselwa ukukhiqiza i-glass fiber ihlukile kuneminye imikhiqizo yengilazi. Ingilazi esetshenziselwa imicu eyenzelwe ukuhweba emhlabeni iqukethe i-silica, i-alumina, i-calcium oxide, i-boron oxide, i-magnesium oxide, i-sodium oxide, njll. ngokusho kokuqukethwe kwe-alkali engilazini, ingahlukaniswa ibe i-alkali free glass fiber. (i-sodium oxide 0% ~ 2%, eyengilazi ye-aluminium borosilicate) kanye ne-alkali glass fiber (i-sodium oxide 8% ~ 12%), ingeye-sodium calcium silicate ingilazi equkethe noma ngaphandle kwe-boron) kanye ne-alkali glass fiber ephezulu (ngaphezu kuka-13% i-sodium oxide ingeyengilazi ye-sodium calcium silicate).

1. I-E-glass, eyaziwa nangokuthi ingilazi yamahhala ye-alkali, iyingilazi ye-borosilicate. Ingxenye yengilazi esetshenziswa kakhulu ye-glass fiber ine-insulation enhle kagesi kanye nezakhiwo zemishini. Isetshenziswa kabanzi ekukhiqizeni i-glass fibre yokufakwa kukagesi kanye ne-glass fiber ye-FRP. Ububi bayo ukuthi kulula ukuguguleka nge-asidi ye-inorganic, ngakho-ke ayifanele indawo ye-asidi.

2. Ingilazi ye-C, eyaziwa nangokuthi ingilazi ye-alkali emaphakathi, ibonakala ngokumelana kangcono namakhemikhali, ikakhulukazi ukumelana ne-asidi, kunengilazi engeyona i-alkali, kodwa ukusebenza kabi kukagesi kanye no-10% ~ 20% wamandla emishini aphansi kune-non-alkali glass fiber. Ngokuvamile, i-alkali glass fiber ephakathi kwamanye amazwe iqukethe inani elithile le-boron trioxide, kuyilapho i-alkali yengilazi yaseShayina i-alkali fiber ayinayo nhlobo i-boron. Emazweni angaphandle, i-medium alkali glass fiber isetshenziselwa kuphela ukukhiqiza imikhiqizo yengilazi engagqwali, efana ne-glass fiber surface ezwakalayo, futhi isetshenziselwa ukuqinisa izinto zokufulela i-asphalt. Kodwa-ke, e-China, i-alkali yengilazi ye-alkali ephakathi ibala ngaphezu kwengxenye (60%) yokukhishwa kwe-glass fiber futhi isetshenziswa kabanzi ekuqiniseni i-FRP kanye nokukhiqizwa kwendwangu yokuhlunga kanye nendwangu yokubopha, Ngoba intengo yayo iphansi kunalokho. ye-alkali free glass fiber, inokuncintisana okuqinile.

3. I-fiber yengilazi yamandla aphezulu ibonakala ngamandla aphezulu kanye ne-modulus ephezulu. Amandla ayo okuqina kwe-fiber eyodwa angama-2800mpa, acishe abe ngama-25% aphezulu kunalawo e-alkali free glass fiber, futhi i-elastic modulus yayo ingu-86000mpa, ephakeme kunaleyo ye-E-glass fiber. Imikhiqizo ye-FRP ekhiqizwa yibo isetshenziswa kakhulu embonini yezempi, indawo, izikhali ezivikela izinhlamvu kanye nemishini yezemidlalo. Kodwa-ke, ngenxa yentengo ephezulu, ayikwazi ukuthandwa ekusetshenzisweni komphakathi, futhi okukhiphayo emhlabeni kumayelana nezinkulungwane zamathani.

4. I-Ar glass fiber, eyaziwa nangokuthi i-alkali resistant glass fiber, ithuthukiswa kakhulu ukuqinisa usimende.

5. Ingilazi, eyaziwa nangokuthi ingilazi ye-alkali ephezulu, iyingilazi evamile ye-sodium silicate. Ayivamisile ukusetshenziselwa ukukhiqiza imicu yengilazi ngenxa yokungazweli kahle kwamanzi.

6. Ingilazi ye-E-CR iyingilazi ethuthukisiwe ye-boron ne-alkali, esetshenziselwa ukukhiqiza i-glass fiber ene-asidi enhle kanye nokuphikiswa kwamanzi. Ukumelana kwayo namanzi kuhle izikhathi ezi-7 ~ 8 kune-alkali free glass fiber, futhi ukumelana kwayo ne-asidi kungcono kakhulu kunokwe-alkali glass fiber. Iwuhlobo olusha olwakhelwe ngokukhethekile amapayipi angaphansi komhlaba kanye namathangi okugcina.

7. Ingilazi ye-D, eyaziwa nangokuthi ingilazi ye-dielectric ephansi, isetshenziselwa ukukhiqiza imicu yengilazi ephansi ye-dielectric enamandla amahle we-dielectric.

Ngaphezu kwalezi zingxenye ze-fiber yengilazi ezingenhla, i-alkali entsha ye-glass fiber iye yavela eminyakeni yamuva nje. Ayiqukethe nhlobo i-boron, ukuze kuncishiswe ukungcoliswa kwemvelo, kodwa ukufakwa kwayo kagesi kanye nezakhiwo zemishini kufana nalezo zengilazi ye-E yendabuko. Ngaphezu kwalokho, kukhona uhlobo lwe-glass fiber enezingxenye zengilazi ezimbili, eziye zasetshenziswa ekukhiqizeni uboya bengilazi. Kuthiwa futhi inamandla njengokuqinisa i-FRP. Ngaphezu kwalokho, kune-fluorine-free glass fiber, okuwumucu wengilazi we-alkali othuthukisiwe othuthukiselwe izidingo zokuvikela imvelo.
