Ukufika Okusha kwe-China Pp Macro Fiber Yemisebenzi Yamanzi - I-Polypropylene Fibers Micro Polypropylene Fiber Reinforced Concrete Fibers PPF Micro Fibers – Kehui

I-polypropylene fiber (PPF) uhlobo lwezinto ze-polymer ezinesisindo esincane, amandla aphezulu, kanye nokumelana nokugqwala. Ukumelana nokuqhekeka kwekhonkrithi kungathuthukiswa ngokungeza imicu ye-polypropylene. I-PPF ingenza ngcono ukusatshalaliswa kosayizi we-pore yekhonkrithi. Ngenxa yalokho, ukuqina kwekhonkrithi kukhuliswa kakhulu njengoba i-PPF ingavimba ukungena kwamanzi noma ama-ion ayingozi kukhonkrithi. Okuqukethwe kwe-fibre okuhlukile, ububanzi be-fibre, kanye nesilinganiso se-fibre hybrid kuzoba nemiphumela ehlukene kuma-index okuqina. Impahla yokuqina kwekhonkrithi ingathuthukiswa ngokuhlanganisa ama-PPF kanye nemicu yensimbi. Izithiyo ze-PPF ekusetshenzisweni kukhonkrithi ukuhlakazeka okungaphelele kukhonkrithi kanye nokubopha okubuthakathaka nge-matrix yesimende. Izindlela zokunqoba lezi zithiyo ukusebenzisa i-fibre eguquliwe nge-nanoactive powder noma ukwelashwa kwamakhemikhali.

I-fibre elwa nokuqhekeka iyi-fiber ephilayo enamandla amakhulu ehlanganisiwe esebenzisa i-polypropylene ye-fiber njengezinto zokusetshenziswa futhi icutshungulwa ngenqubo ekhethekile. Inokumelana okunamandla kwe-asidi, ukumelana okunamandla kwe-alkali, ukuguquguquka kokushisa okubuthakathaka, kanye nezakhiwo zamakhemikhali ezizinzile kakhulu. Ukwengeza i-mortar noma i-concrete kungalawula ngempumelelo imifantu emincane ebangelwa izinguquko zokushisa esigabeni sokuqala sokuncipha kwepulasitiki ye-mortar ne-concrete, kuvimbele futhi kuvimbele ukwakheka nokuthuthukiswa kwemifantu, futhi kuthuthukise kakhulu ukumelana kwemifantu ye-concrete, ukungangeni kwamanzi, ukumelana nomthelela kanye nokumelana nokuzamazama komhlaba kungasetshenziswa kabanzi kubunjiniyela obungaphansi komhlaba. Ukuvimbela amanzi, uphahla, izindonga, phansi, amachibi, amakamelo angaphansi komhlaba, imigwaqo namabhuloho kumaphrojekthi okwakha ezimboni nasezakhiweni zomphakathi. Kuyinto entsha efanelekile yobunjiniyela be-mortar ne-concrete enokumelana nokuqhekeka, ukumelana nokuvuza kanye nokuhuzuka.

Imisebenzi Eyinhloko:
Njengento yokuqinisa yesibili yekhonkrithi, i-polypropylene fiber ingathuthukisa kakhulu ukumelana kwayo nokuqhekeka, ukungangeni kwamanzi, ukumelana nomthelela, ukumelana nokuzamazama komhlaba, ukumelana nesithwathwa, ukumelana nokuguguleka, ukumelana nokuqhuma, ukumelana nokuguga nokusebenza, ukumpompa, kanye nokugcinwa kwamanzi.
● Vimbela ukuvela kwemifantu yekhonkrithi
● Thuthukisa ukungangeni kahle kokhonkolo
● Thuthukisa ukumelana nokuncibilika kwekhonkrithi
● Thuthukisa ukumelana nomthelela, ukumelana nokuguquguquka, ukumelana nokukhathala kanye nokusebenza kokuzamazama komhlaba kwekhonkrithi
● Thuthukisa ukuqina nokumelana nokuguga kwekhonkrithi
● Thuthukisa ukumelana nomlilo kwekhonkrithi

Izindawo Zokufaka Isicelo:
Isakhiwo esiqinile esingangeni manzi sikakhonkolo:
Iphansi elingaphansi, udonga oluseceleni, uphahla, i-slab efakwe uphahla, idamu, njll. Ubunjiniyela, amaphrojekthi okulondolozwa kwamanzi, imigwaqo engaphansi komhlaba, imigwaqo yezindiza, iziteshi zechweba, amadekhi e-viaduct adlula ngaphezulu, izinsika, izakhiwo ezinde kakhulu ezinezidingo eziphezulu zokumelana nokuqhekeka, ukumelana nokushayisana, kanye nokumelana nokuguguleka.

Udaka Lwesimende:
Ukupenda odongeni kwangaphakathi (kwangaphandle), ukuplasta ukhonkolo olunomoya, i-putty yokuhlobisa kwangaphakathi kanye nodaka lokuvikela ukushisa.
Ubunjiniyela obulwa nokuqhuma nokumelana nomlilo:
Amaphrojekthi ezempi zokuzivikela emoyeni, amapulatifomu kawoyela, oshimula, izinto eziphikisayo, njll.

I-Shotcrete:
Umhubhe, ulwelwesi lwe-culvert, isakhiwo esinodonga oluncane, ukuqinisa umthambeka, njll.
Imiyalelo yokusebenzisa
Isilinganiso esiphakanyisiwe:
Inani elinconywayo lodaka ngesikwele ngasinye sodaka olujwayelekile lokuplasta lingu-0.9 ～1.2kg
Inani elinconywayo lodaka lokushisa ngethani: 1 ～3kg
Inani elinconywayo lekhonkrithi nge-cubic meter ngayinye yekhonkrithi yileli: 0.6 ~ 1.8kg (ngokwereferensi)

Ubuchwepheshe bokwakha nezinyathelo
①Ngokusho komthamo wekhonkrithi exutshwe isikhathi ngasinye, isisindo sefayibha engeziwe isikhathi ngasinye silinganiswa ngokunembile ngokwezidingo zesilinganiso senhlanganisela (noma inani lokuxuba elinconywayo).
② Ngemva kokulungisa isihlabathi kanye nogwadule, engeza i-fiber. Kunconywa ukusebenzisa i-forced mixer. Faka i-aggregate kanye ne-fiber ku-mixer, kodwa qaphela ukuqinisekisa ukuthi i-fiber ifakiwe phakathi kwe-aggregate bese uyixuba yome cishe imizuzwana engama-30. Ngemva kokufaka amanzi, yixube imanzi cishe imizuzwana engama-30 ukuze ihlakazeke ngokuphelele i-fiber.
③ Thatha amasampula ngokushesha ngemva kokuxuba. Uma imicu ihlakazeke ngokulinganayo yaba yi-monofilaments, ukhonkolo ungasetshenziswa. Uma kusekhona imicu ehlanganisiwe, yandisa isikhathi sokuxuba ngemizuzwana engama-20-30 ngaphambi kokusebenzisa.
④ Inqubo yokwakha nokulungisa ikhonkrithi efakwe ifayibha ifana ncamashi nekhonkrithi evamile. Ilungele ukusetshenziswa.
