IiFayibha zePolypropylene IiFayibha eziNcinane zePolypropylene ezomeleziweyo iiFayibha zeConcrete zePPF iiFiber ezincinci
Ifayibha yePolypropylene (PPF) luhlobo lwemathiriyeli yepolymer enobunzima obulula, amandla aphezulu, kunye nokumelana nomhlwa. Ukumelana nokuqhekeka kwekhonkrithi kunokuphuculwa ngokudibanisa iifiber ze-polypropylene. I-PPF inokwandisa ubungakanani bepore yokuhanjiswa kwekhonkrithi. Ngenxa yoko, ukuqina kwekhonkrithi kuphuculwe kakhulu kuba i-PPF inokuthintela ukungena kwamanzi okanye i-ion ezinobungozi kwikhonkrithi. Umxholo wefiber owahlukileyo, i-fiber diameter, kunye ne-fiber hybrid ratio iya kuba neziphumo ezahlukeneyo kwizalathisi zokuqina. Ipropati ehlala ixesha elide yekhonkrithi ingaphuculwa ngakumbi ngokudibanisa ii-PPF kunye neentambo zetsimbi. Ukungaphumeleli kwe-PPF kwisicelo kwikhonkrithi yi-dispersion engaphelelanga kwikhonkrithi kunye nobuthakathaka bokubambisana kunye ne-matrix ye-samente. Iindlela zokunqoba ezi zithintelo kukusebenzisa i-fiber eguqulwe nge-nanoactive powder okanye unyango lwekhemikhali.
I-anti-cracking fiber yi-high-power bundled monofilament organic fiber esebenzisa i-fiber-grade polypropylene njengento eluhlaza kwaye iqhutywe yinkqubo ekhethekileyo. Inokumelana ne-asidi eyomeleleyo, ukuxhathisa okuqinileyo kwe-alkali, ukuhanjiswa kwe-thermal obuthathaka, kunye neepropathi zekhemikhali ezizinzileyo. Ukongeza udaka okanye ikhonkrithi inokulawula ngokufanelekileyo i-micro-cracks ebangelwa utshintsho lobushushu kwisigaba sokuqala sokushwabana kweplastiki yodaka kunye nekhonkrithi, ukuthintela kunye nokuthintela ukubunjwa kunye nophuhliso lweentanda, kunye nokuphucula kakhulu ukuxhathisa ukuqhekeka kwekhonkrithi, ukunganyanzeki, ukuxhathisa impembelelo kunye nokuzamazama komhlaba. ukuxhathisa kunokusetyenziswa ngokubanzi kubunjineli obuphantsi komhlaba ekungangeni kwamanzi, uphahla, iindonga, imigangatho, amadama, amagumbi angaphantsi, iindlela kunye neebhulorho kwiiprojekthi zoshishino kunye nolwakhiwo lwasekuhlaleni. Yinto entsha efanelekileyo yodaka kunye nobunjineli bekhonkrithi ene-anti-cracking, i-anti-seepage kunye ne-abrasion resistance.

Iteknoloji yokwakha kunye namanyathelo
① Ngokomthamo wekhonkrithi exutywe ngexesha ngalinye, ubunzima befiber eyongeziweyo ngexesha ngalinye bulinganiswa ngokuchanekileyo ngokweemfuno zomxube womxube (okanye umxube ocetyiswayo).
② Emva kokulungisa isanti kunye negrabile, yongeza i-fiber. Kunconywa ukusebenzisa umxube onyanzelekileyo. Yongeza i-aggregate kunye nefiber kwi-mixer, kodwa qaphela ukuqinisekisa ukuba i-fiber yongezwa phakathi kwe-aggregate kwaye uyixube yome malunga nemizuzwana engama-30. Emva kokongeza amanzi, yixube imanzi malunga nemizuzwana engama-30 ukusasaza ngokupheleleyo ifayibha.
③ Thatha iisampuli ngokukhawuleza emva kokuxuba. Ukuba iifiber ziye zahlakazwa ngokulinganayo kwi-monofilaments, ikhonkrithi ingasetyenziswa. Ukuba kusekho imicu edibeneyo, yandisa ixesha lokuxuba nge-20-30 imizuzwana ngaphambi kokusetyenziswa.
④ Inkqubo yolwakhiwo kunye nokugcinwa kwefayibha eyongeziweyo ifana ngqo naleyo yekhonkrithi eqhelekileyo. Ukulungele ukusetyenziswa.
