IFayibha yePolypropylene
Ifayibha yePolypropylene yinto entsha ephucula kakhulu iimpawu zokusebenza zekhonkrithi kunye nodaka, iyenza ibe yinxalenye ebalulekileyo kwizicelo zokwakha zale mihla. Le fiber yokwenziwa inoluhlu lweepropathi ezinenzuzo eziphucula imiba ephambili yentembeko yesakhiwo, ukuqina, kunye nobomi obude. Olunye uncedo oluphawulekayo lokubandakanya i-polypropylene fiber kwi-concrete kunye nodaka ngumthamo wayo wokuphucula ukuxhathisa ukuqhekeka. Ukuqhekeka ngomnye wemiba eqhelekileyo kwizakhiwo zekhonkrithi, ehlala ibangelwa kuxinzelelo lokusingqongileyo, ukuguquguquka kwamaqondo obushushu, okanye ukomisa ukuncipha. Ukuqaliswa kweefayili ze-polypropylene kudala i-matrix ngaphakathi kwezinto eziphathekayo, ukusabalalisa uxinzelelo ngokulinganayo kunye nokunceda ukuthintela ukubunjwa kweentanda, ezinokuthi ziphazamise ukunyaniseka kwezakhiwo kunye nezinye izakhiwo.
Ukongeza kokuxhathisa okuchukumisayo kokuqhekeka, ifayibha yepolypropylene ikwabonelela ngokuqina kokumelana nokungena kwamanzi, uphawu olubalulekileyo olukhusela ikhonkrithi kunye nodaka ekungeneni kokufuma. Olu phawu lubaluleke kakhulu kwiindawo apho ikhonkrithi ibonakaliswe kwiimeko zemozulu ezimandundu okanye apho ukuvezwa kwamanzi rhoqo. Ngokunciphisa ukungena kwamanzi, iifiber ze-polypropylene zinceda ukukhusela umonakalo obangelwa yimijikelezo ye-freeze-thaw, enokukhokelela ekugqithiseni kunye nokuwohloka kwexesha. Ngaphaya koko, iintsinga zongeza ukuxhathisa kwe-abrasion kwikhonkrithi kunye nodaka, nto leyo iyenza yomelele ngakumbi ukunxiba kunye nokukrazula kumandla oomatshini okanye ukukhuhlana, okubalulekileyo kwiindawo ezihlala zihamba rhoqo okanye imithwalo enzima.
Enye inzuzo ebalulekileyo yokusebenzisa i-polypropylene fiber ekwakheni igalelo layo ekuxhathiseni iqabaka. Kwimimandla enemozulu ebandayo, izakhiwo zekhonkrithi zihlala zisengozini yomonakalo ngenxa yeqondo lokushisa elibandayo elinokukhokelela ekubunjweni komkhenkce ngaphakathi kwezinto. Ubukho bemicu yepolypropylene kunceda ukunciphisa lo mngcipheko ngokudala ulwakhiwo oluthambileyo noluqilima olunokumelana neziphumo zokukhenkceza kunye nokunyibilika. Ukongeza, ezi ntsinga zidlala indima ebalulekileyo ekuxhathiseni ugqabhuko-dubulo ngokuphucula iimpawu zokufunxa amandla ekhonkrithi, ziyenze ikwazi ukumelana noxinzelelo olugqithisileyo okanye uxinzelelo.
Ukusebenza ngenye indawo apho i-polypropylene fiber ikhanya khona. Xa ixutywe kwikhonkrithi kunye nodaka, le micu inceda ukuphucula ukuhamba kunye nokusingatha iipropati zezinto eziphathekayo, okuvumela ukusetyenziswa kakuhle kunye nokudibanisa okungcono. Oku kuphucuka kokusebenza akuncedi nje ekubeni kube lula ulwakhiwo kodwa kukwaqinisekisa ukusasazwa okufanayo kunye nokusebenza kakuhle kweentsinga kulo lonke umxube, ukwandisa inzuzo yazo yokuqinisa.
Ngaphandle kwezi zibonelelo zobugcisa, ukuhlanganiswa kweefayili ze-polypropylene nazo zinokuba nefuthe lexesha elide lokugcinwa kunye nobude bezakhiwo. Ngokunceda ukuthintela ukugqwala ekuqiniseni intsimbi, iifiber ze-polypropylene zikhuthaza ubomi obude benkonzo yeprojekthi yonke. Oku kuncitshiswa kwemfuno yokulungiswa kunye nokugcinwa kuguqulela ukugcinwa kweendleko ezibalulekileyo kwixesha lokuphila kwesakhiwo, okwenza utyalo-mali lokuqala kwi-polypropylene fiber luxabiseke kwiinkampani zokwakha kunye nabaxhasi ngokufanayo.
Isishwankathelo, i-polypropylene fiber ibonakala njengento eguqukayo kwintsimi yekhonkrithi kunye nezicelo zodaka. Izibonelelo zayo ezininzi-ezisusela ekuphuculweni kwe-crack kunye nokuchasana kwamanzi ukuya ekuphuculweni kokusebenza kunye nobomi benkonzo obude-buyenza ibe yongezelelo oluxabisekileyo kwimisebenzi yolwakhiwo lwangoku. Ngophando oluqhubekayo kunye nokuqhubela phambili kwitekhnoloji yezixhobo, ikamva le-polypropylene fiber ekwandiseni ukusebenza kolwakhiwo lihlala lithembisa, livula indlela yezisombululo zokwakha ezikhuselekileyo, ezihlala ixesha elide, kunye nezoqoqosho ezinokwenzeka kwiindawo ezahlukeneyo.
