Iifayibha zobunjineli ze-High Tenacity Anti-Crack Pp – Iifayibha ze-Polypropylene Micro Polypropylene Fiber Reinforced Concrete Fibers PPF Micro Fibers – Kehui

I-polypropylene fiber (PPF) luhlobo lwezinto ze-polymer ezinobunzima obulula, amandla aphezulu, kunye nokumelana nokugqwala. Ukumelana nokuqhekeka kwekhonkrithi kunokuphuculwa ngokongeza ii-polypropylene fibers. I-PPF inokuphucula ukusasazwa kobungakanani be-pore yekhonkrithi. Ngenxa yoko, ukuqina kwekhonkrithi kuphuculwe kakhulu kuba i-PPF inokuthintela ukungena kwamanzi okanye ii-ion eziyingozi kwikhonkrithi. Umxholo wefayibha owahlukileyo, ububanzi befayibha, kunye nomlinganiselo we-fiber hybrid kuya kuba nemiphumo eyahlukileyo kwi-durability indexes. Ipropati yokuqina kwekhonkrithi inokuphuculwa ngakumbi ngokudibanisa ii-PPF kunye neefayibha zentsimbi. Iingxaki ze-PPF ekusetyenzisweni kwikhonkrithi kukusabalalisa okungaphelelanga kwikhonkrithi kunye nokubopha okubuthathaka kunye ne-matrix yesamente. Iindlela zokoyisa ezi ngxaki kukusebenzisa i-fibre modified nge-nanoactive powder okanye unyango lwekhemikhali.

Ifayibha echasene nokuqhekeka yifayibha yendalo ene-monofilament enamandla aphezulu ehlanganiswe ne-polypropylene yefayibha njengezinto eziluhlaza kwaye icutshungulwa ngenkqubo ekhethekileyo. Inokumelana okunamandla kwe-asidi, ukumelana okunamandla kwe-alkali, ukuqhuba kobushushu obuphantsi, kunye neempawu zeekhemikhali ezizinzileyo kakhulu. Ukongeza i-mortar okanye i-concrete kunokulawula ngokufanelekileyo ukuqhekeka okubangelwa kukutshintsha kobushushu kwinqanaba lokuqala lokushwabana kweplastiki ye-mortar kunye ne-concrete, kuthintele kwaye kuthintele ukwakheka kunye nophuhliso lwee-cracks, kwaye kuphucule kakhulu ukumelana kwee-cracks ze-concrete, ukungangeni kwamanzi, ukumelana neempembelelo kunye nokumelana ne-inyikima kunokusetyenziswa kakhulu kubunjineli obungaphantsi komhlaba. Ukuthintela ukungenwa kwamanzi, uphahla, iindonga, umgangatho, amachibi, amagumbi angaphantsi komhlaba, iindlela kunye neebhulorho kwiiprojekthi zokwakha zoshishino nezoluntu. Sisixhobo esitsha esifanelekileyo sobunjineli be-mortar kunye ne-concrete kunye nokumelana nokuqhekeka, ukumelana nokuvuza kunye nokurhawuzelelwa.

Itekhnoloji yokwakha kunye namanyathelo
①Ngokwevolumu yesamente exutywe ngalo lonke ixesha, ubunzima befayibha eyongeziweyo ngalo lonke ixesha bulinganiswa ngokuchanekileyo ngokweemfuno zomlinganiselo womxube (okanye ubungakanani bomxube obucetyiswayo).
② Emva kokulungisa isanti kunye negrabile, yongeza ifayibha. Kucetyiswa ukuba usebenzise umxube ophoqelelweyo. Yongeza i-aggregate kunye nefayibha kwi-mixer, kodwa qaphela ukuqinisekisa ukuba ifayibha yongezwa phakathi kwe-aggregate kwaye uyixube yome malunga nemizuzwana engama-30. Emva kokongeza amanzi, yixube imanzi malunga nemizuzwana engama-30 ukuze isasazeke ngokupheleleyo ifayibha.
③ Thatha iisampulu ngoko nangoko emva kokuxuba. Ukuba imicu isasazwe ngokulinganayo kwi-monofilaments, ikhonkrithi ingasetyenziswa. Ukuba kusekho imicu ehlanganisiweyo, yandisa ixesha lokuxuba ngemizuzwana engama-20-30 ngaphambi kokusebenzisa.
④ Inkqubo yokwakha nokugcina ikhonkrithi eyongeziweyo ngefayibha ifana nqwa nekhonkrithi eqhelekileyo. Ilungele ukusetyenziswa.
