Iindidi ezahlukeneyo zeFiber eQinisekisiweyo eKhonkrithi

1. I-Fiber yentsimbi eQinisekisiweyo

Inani leentlobo ze-fiber zensimbi ziyafumaneka njengokuqinisa.Ifiber yentsimbi engqukuva uhlobo olusetyenziswa ngokuqhelekileyo iveliswa ngokusika ucingo olungqukuva ukuya kubude obufutshane.Ububanzi obuqhelekileyo buphakathi kwe-0.25 ukuya kwi-0.75mm.Iintsinga zentsimbi ezinoxande c/s ziveliswa ngokufaka intlenga yamaphepha malunga ne-0.25mm ubukhulu.

Ifayibha eyenziwe ngentsimbi ethambileyo yocingo oluzotyiweyo.Ukungqinelana ne-IS:280-1976 kunye nobubanzi bocingo olusuka ku-0.3 ukuya kwi-0.5mm zisetyenziswe ngokubonakalayo eIndiya.

Imicu yentsimbi ejikelezayo iveliswa ngokusika okanye ukunqunqa ucingo, iintsinga zeshiti ezisicaba ezinee-c/s eziqhelekileyo ukusuka kwi-0.15 ukuya kwi-0.41mm ubukhulu kunye no-0.25 ukuya kwi-0.90mm ububanzi ziveliswa ngokufaka i-silting sheet sheet.

I-fiber ephosakeleyo, eboshwe ngokukhululekileyo kunye neglue e-soluble yamanzi ngendlela ye-bundle iyafumaneka.Kuba iintsinga zomntu ngamnye zithande ukuhlangana kunye, ukuhanjiswa kwazo okufanayo kwi-matrix kuhlala kunzima.Oku kunokuphetshwa ngokongeza iinyanda zefibers, ezahlula ngexesha lokuxuba.

 

2. I-Polypropylene Fiber Reinforced (PFR) udaka lwesamente kunye nekhonkrithi

I-Polypropylene yenye yezona zinto zinexabiso eliphantsi kwaye zifumaneka kakhulu iipolymers zepolypropylene fibers ziyakwazi ukumelana neekhemikhali ezininzi kwaye iya kuba yimatrix yesamente enokonakala kuqala kuhlaselo lwekhemikhali olundlongondlongo.Indawo yayo yokunyibilika iphezulu (malunga ne-165 degrees centigrade).Ngoko ke isantya esisebenzayo.Njengoko (i-100 degree centigrade) inokugcinwa ixesha elifutshane ngaphandle kokulimaza iimpawu zefiber.

Iifiber ze-polypropylene zibe yi-hydrophobic zinokuxutywa ngokulula njengoko zingadingi unxibelelwano olude ngexesha lokuxuba kwaye zifuna ukuxinzezeleka ngokulinganayo kumxube.

Iifiber ezimfutshane ze-Polypropylene kwiinqununu ezincinci zomthamo phakathi kwe-0.5 ukuya kwi-15 ezisetyenziselwa urhwebo kwikhonkrithi.

3. I-GFRC - I-Glass Fiber Reinforced Concrete

Ifayibha yeglasi yenziwe ukusuka kwi-200-400 yeefilaments zomntu ezibotshwe kancinci ukwenza istand.Ezi zitendi zinokunqunyulwa zibe bubude obahlukeneyo, okanye zidityaniswe ukwenza imathi yelaphu okanye iteyiphu.Ukusebenzisa iindlela zokuxuba eziqhelekileyo kwikhonkrithi eqhelekileyo akunakwenzeka ukuxuba ngaphezu kwe-2% (ngomthamo) weefayili zobude be-25mm.

Esona sixhobo siphambili sosinga lweglasi ibikukomeleza isamente okanye iimatriki zodaka ezisetyenziswa kwimveliso yamaphepha amancinci.Iingqinisiso eziqhelekileyo ezisetyenziswayo zeefiber zeglasi zisetyenziswa yi-e-glass.Ekuqinisweni kweeplastiki kunye neglasi ye-AR i-glass ye-E-iglasi ayinakuchasana ngokwaneleyo kwi-alkali ekhoyo kwi-samente yasePortland apho i-AR-glass iphucule iimpawu zokumelana ne-alkali.Ngamanye amaxesha iipolymers nazo zongezwa kwimixube ukuphucula ezinye iimpawu zomzimba ezifana nokuhamba kokufuma.

4. IiFayibha zeAsbestos

Ifiber yeminerali efumaneka ngokwendalo engabizi kakhulu, iasbestos, idityaniswe ngempumelelo kunye nePortland sement paste ukwenza imveliso esetyenziswa ngokubanzi ebizwa ngesamente yeasbestos.Iintsinga ze-asbestos apha zisebenza ngoomatshini kunye nokumelana neekhemikhali zibenza zilungele imibhobho yemveliso yeshiti, iithayile kunye nezinto ezifulelweyo.Ibhodi yesamente yeAsbestos imalunga namaxesha amabini okanye amane lawo matrix angaqiniswanga.Nangona kunjalo, ngenxa yobude obufutshane (10mm) ifayibha inamandla empembelelo ephantsi.

5. IiFiber zeCarbon

Iifayibha zekhabhoni ezisuka kolona lwamva nje & nokwenzeka ukuba longezo lunomtsalane kuluhlu lwefiber ekhoyo ukuze kusetyenziswe urhwebo.Ifayibha yekhabhoni ingena phantsi kwemodulus ephezulu kakhulu yokuqina kunye namandla aguqukayo.Ezi zibanzi.Amandla abo kunye neempawu zokuqina zifunyenwe ziphezulu nakwezo zentsimbi.Kodwa basemngciphekweni wokonakala ngakumbi kunefiber yeglasi, kwaye ke ngoko baphathwa ngokurhoxa.

6. Iintsinga ze-Organic

I-Organic fiber efana ne-polypropylene okanye i-fiber yendalo inokuba yi-inert yekhemikhali ngakumbi kunentsimbi okanye i-glass fibers.Zikwangabizi kakhulu, ngakumbi ukuba zendalo.Umthamo omkhulu wefiber yemifuno ungasetyenziselwa ukufumana i-composite yokuqhekeka okuninzi.Ingxaki yokuxuba kunye ne-uniform dispersion inokusonjululwa ngokongeza i-superplasticizer.
