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 inokuphuculwa 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 ixesha ngalinye lilinganiswa 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.
Iifiber ze-Micro polypropylene (PP) zisetyenziswa ngokuqhelekileyo njengento yokuqinisa kwizicelo ze-shotcrete. IShotcrete, ekwaziwa njengekhonkrithi etshiziweyo, yindlela yokugalela ikhonkrithi kusetyenziswa umbhobho wokutshiza wepneumatic onesantya esiphezulu. Ukongezwa kweefiber ezincinci zePP kwi-shotcrete kubonelela ngeenzuzo ezininzi:

Ulawulo lokuqhekeka:

Iifiber ezincinci zePP zinceda ukulawula ukuphuhliswa kweentanda kwizicelo ze-shotcrete. Benza njengokuqiniswa kwesibini, ukubonelela ngenkxaso eyongezelelweyo kunye nokunciphisa amandla okuqhekeka ukusabalalisa.
Ukuphuculwa koKuhlala ixesha elide:

Ukubandakanywa kwe-micro PP fibers kwandisa ukuqina kwe-shotcrete ngokunyusa ukuxhathisa kwayo ekuqhekekeni, ngakumbi kwiimeko ezibuhlungu zokusingqongileyo okanye xa ibonakaliswe kwimijikelo yokuqhaqhazela.
Uchaso lweMpembelelo olomeleziweyo:

IMicro PP fibers inegalelo kwimpembelelo yokuchasa i-shotcrete, iyenza yomelele ngakumbi kwaye ikwazi ukumelana namandla anje ngempembelelo okanye i-abrasion. Oku kubaluleke kakhulu kwizicelo ezifana ne-tunnel linings okanye iindonga ezigcinayo.
UkuNcitshiswa kwePlastiki eNcincisayo yokuNcandeka:

Kwinqanaba lokuqala lokunyanga, i-shotcrete inokuba sesichengeni sokuqhekeka kweplastiki. Iintsinga ezincinci zePP zinceda ukunciphisa lo mba ngokunciphisa ukubakho kunye nobungakanani bokuqhekeka okunjalo.
Ukuqina Okunyukayo:

Ukongezwa kwe-micro PP fibers kuphucula ukuqina kwe-shotcrete, iyenza ibe yi-ductile kwaye imelane nokulayisha okuguquguqukayo. Oku kubaluleke kakhulu kwizicelo apho i-shotcrete inokuthi ixhomekeke kwintshukumo yesakhiwo okanye amandla e-seismic.
Ukuxhathisa ukonakala:

IMicro PP fibers ayidleki, inika ukuqina kwexesha elide kunye nokuchasana nokuthotywa kweendawo ezinobundlobongela. Oku kuchasene nokuqiniswa kwentsimbi, enokuthi idle ixesha elide.
Ukuphuculwa kokuSebenza kweShotcrete:

Ukusetyenziswa kwe-micro PP fibers kunokunyusa ukusebenza kwe-shotcrete, okwenza kube lula ukuphatha kunye nokutshiza. Oku kubalulekile ukufezekisa isicelo esifanayo kunye nokugqiba okufunwayo.
Xa udibanisa iintsinga ezincinci zePP kwimixube yeshotcrete, kubalulekile ukulandela izikhokelo zoyilo lomxube olufanelekileyo. Umxholo wefiber, ubude, kunye nokusabalalisa ngaphakathi komxube we-shotcrete kufuneka kuqwalaselwe ngononophelo ukufezekisa iimpawu zokusebenza ezifunwayo. Amanyathelo okulawula umgangatho kunye novavanyo kufuneka luphunyezwe ukuqinisekisa ukuba i-shotcrete ihlangabezana neenkcukacha zeprojekthi kunye nemigangatho yoshishino efanelekileyo.

Njengaso nasiphi na isongezelelo esibambekayo, ukudibana nengcaphephe ye-shotcrete okanye injineli yolwakhiwo kuyacetyiswa ukuba uqinisekise ukuba i-PP ekhethiweyo yokuqinisa ifayibha encinci ihambelana nokusebenza kunye neemfuno zokhuseleko lwesicelo se-shotcrete ethile. Ukongezelela, iikhowudi zokwakha zendawo kunye nemigangatho kufuneka ithathelwe ingqalelo.
