Yintoni iPP fiber?

PP ifayibhaimele i-polypropylene fibre, elulutya lwenziwe olwenziwe ngepolymerized propylene. Yimathiriyeli eguquguqukayo enezicelo ezahlukeneyo kumashishini afana nelaphu, iimoto, ulwakhiwo, kunye nokupakishwa. Kumxholo wokwakha, iifayili zePP zisetyenziswa ngokuqhelekileyo njengezinto zokuqiniswa kwikhonkrithi ukuze kuphuculwe iipropati kunye nokusebenza kwayo. Nantsi isishwankathelo sePP fiber:

Iipropati zePP IFayibha:

1. Amandla: Iifiber zePP zinamandla aphezulu, ezinegalelo ekuqinisweni kwekhonkrithi kunye nokwandisa ukuqina kwayo jikelele kunye nokuchasana nokuqhekeka.
2. Ukuguquguquka: Iifayili zePP ziguquguqukayo kwaye zinokuxutywa ngokulula kwimixube yekhonkrithi ngaphandle kokuchaphazela ukusebenza kwekhonkrithi.
3. Ukumelana neMichiza: I-Polypropylene ixhathisa kwiikhemikhali ezininzi, yenza iifiber ze-PP zilungele ukusetyenziswa kwiindawo ezibuhlungu apho ikhonkrithi inokuvezwa kwizinto ezitshabalalisayo.
4. Ukumelana naManzi: Iifiber zePP ziyi-hydrophobic kwaye ayifuni amanzi, enceda ukuthintela ukufunxa komswakama kunye nokuwohloka kwekhonkrithi.
5. I-Lightweight: I-PP fibers ilula, eyenza lula ukuphatha kunye neenkqubo zokuxuba ngexesha lemveliso yekhonkrithi.
6. Ukuzinza kwe-Thermal: Iifayili ze-PP zinozinzo oluhle lwe-thermal kwaye zigcina iipropati zazo kuluhlu olubanzi lwamaqondo okushisa.

Ukusetyenziswa kweFayibha yePP kwiConcrete:

1. Ukulawulwa kwe-Crack: I-PP fibers inceda ukulawula i-plastic shrinkage cracking kwikhonkrithi ngokunciphisa ukubunjwa kunye nokusasazwa kwee-cracks ezibangelwa ukomisa i-shrinkage.
2. Ukuchasana neMpembelelo: Iifayili zePP ziphucula ukuchasana kwempembelelo yekhonkrithi, okwenza ukuba ifaneleke kwizicelo apho ukulayishwa kwempembelelo kuyinkxalabo, njengemigangatho yezoshishino kunye neepavements.
3. Ukuchasana ne-Abrasion: Ukongezwa kwee-fibers ze-PP kwandisa ukunyanzeliswa kwe-abrasion ye-concrete surface, kwandisa ubomi babo benkonzo kwiindawo ezinabantu abaninzi.
4. Ukuphuculwa kokuqina: Iifayili zePP zonyusa ukuqina kunye ne-ductility yekhonkrithi, ephucula amandla ayo okumelana nokulayisha okuguquguqukayo kunye nemikhosi ye-seismic.
5. I-Shotcrete kunye nokuLungisa ii-Mortars: Iifayili zePP zisetyenziselwa izicelo ze-shotcrete kunye nokulungiswa kwee-mortars zokuphucula ukusebenza kwazo kunye nokuqina.
6. I-Fiber-Reinforced Concrete (i-FRC): Iifayili ze-PP zihlala zisetyenziselwa ukudibanisa kunye nezinye iintlobo zemicu (umzekelo, iifayili zetsimbi) ukuvelisa ikhonkrithi eqiniswe ngefayibha kunye neempawu eziphezulu zemishini.

Ukufakela kunye nokuxuba:

• Iifiber zePP zongezwa kumxube wekhonkrithi ngexesha lokudibanisa okanye ukuxuba, nokuba kukwimo eyomileyo okanye isasazwe kwangaphambili emanzini.
• Umthamo we-PP fibers uxhomekeke kwiimpawu zokusebenza ezifunwayo zekhonkrithi kwaye ngokuqhelekileyo zichazwe ngumenzi okanye injineli.
• Ukuxuba okufanelekileyo kubalulekile ukuqinisekisa ukuhanjiswa okufanayo kweentsinga kwi-matrix yekhonkrithi.

Isiphelo:

Ukomelezwa kwefayibha yePP ibonelela ngeenzuzo ezininzi kulwakhiwo lwekhonkrithi, kubandakanywa nokuphuculwa kolawulo lokuqhekeka, ukuxhathisa impembelelo, ukunganyangeki kwe-abrasion, kunye nokuqina. Ngokubandakanya iifiber zePP kwimixube yekhonkrithi, iinjineli kunye neekontraka zinokunyusa ukusebenza kunye nobomi obude bezakhiwo zekhonkrithi, ezikhokelela ekongeni kweendleko kunye nokuqina okwandisiweyo.
