I-Polypropylene Fiber (PP Fiber)iye yavela njengesengezo esibalulekile kwezobunjiniyela obuphathekayo, obaziwa ngekhono labo lokuukuthuthukisa ukuqina,nciphisa ukuqhekeka, futhithuthukisa ukumelana nomthelela. Uma kuhlanganiswe kahle, lezi ziqinisekiso ezincane zisebenza njengama-elementi aqinile asakazwayo, avala imifantu emincane futhi asabalalise kabusha ingcindezi ukuze athuthukise ubuqotho besakhiwo.

Nokho, umthamo ongafanele—noma ngabe udlulele noma ungenele—ungaphazamisa ukusebenza, ogcizelela ukubaluleka kokusetshenziswa okunembile.

Iqhaza le-PP Fiber ku-Concrete Mix

I-PP Fiber iletha izinzuzo ezintathu ezibalulekile zobunjiniyela:

1. Ukunciphisa Ukuqhekeka: Ngesikhathi sokwelashwa kwasekuqaleni, ivimbela ukushwabana kwepulasitiki ngokuvala imifantu emincane esanda kuzalwa, ivimbele ukusabalala kwayo emaphutheni abonakalayo.

2. Ukuqinisa Ukuqina: Ngokuthuthukisa i-ductility, i-PP Fiber ithuthukisa amandla kakhonkolo okumunca umthelela nokukhathala, inciphisa izingozi zokuphuka okuphukayo.

3. Ukwengezwa Kokuqina: Ngokugcwalisa okungenalutho kanye nokulungiswa kwe-crack, kunciphisa ukungakwazi ukungena, ukuvikela ekungeneni kwamanzi, ukugqwala kwamakhemikhali, kanye nokuwohloka kwe-rebar.

Imiphumela Yokhonkolo Ongeyona I-Fiber

♦ I-Plastiki Shrinkage Cracking

Uma ingekho i-PP Fiber: Ukuhwamuka komswakama osheshayo kudala ukuqhekeka kwendawo (ububanzi obungu-0.3–2 mm) phakathi namahora angu-24, kubeke engcupheni ubuqotho bobuso.
Nge-PP Fiber: Ukusebenzisana kwe-fiber-matrix kunciphisa ukuqhekeka kwesigaba sangaphambi kwesikhathingaphezulu kuka-70%.

♦ Impact Resistance Deficiency

Ukhonkolo ongaqinisiwe: Ibonisa ukwehluleka okuqinile ngaphansi kuka-30 J wamandla omthelela (isb, ukushayisana kwe-forklift noma ukulayisha okuguquguqukayo).
Ukhonkolo oqiniswe nge-fiber: Umthamo wokumunca amandla uyakhula2-4 izikhathi, ukunciphisa izingozi zokuphuka.

♦ Ukwehliswa Okusheshisiwe Kokuqina

Ngaphandle kwe-PP Fiber: Imifantu engalawuleki isiza ukungena kwamanzi ne-chloride, isheshise ukugqwala kwe-rebar kanye nokusabalala kwendawo.
Nge-PP Fiber: Ukulawula ukuqhekeka okuqinile (60%, ukwelula impilo yesevisi ngoIminyaka engu-8-12ezindaweni ezinzima.

Ukuqhathanisa Ukusebenza Okuningi

Idatha yobuningi elandelayo ibonisa izinzuzo ezibambekayo ze-PP Fiber kumamethrikhi okusebenza angukhiye:

Izingozi ze-PP Fiber Dosage Engafanele

1. I-Fiber Addition enganele

•Ukuhluleka kokulawula ukuqhekeka: Ukuqiniswa okunganele kuvumela ukuqhekeka kwe-shrinkage ukuba banziswe40%(isb., izinhlelo zokusebenza ze-slab).

•Ukwehla Kokusebenza Okunomthelela: Umthamo womthwalo onamandla wehla30%–50%, okwandisa ubungozi kuthrafikhi noma umthwalo wokuzamazama komhlaba.

•I-Corrosion Acceleration: Amazinga okungena kwe-Chloride akhuphuka60%ezindaweni zasolwandle, okuphazamisa ukuvikelwa kwe-rebar.

2. I-Fiber Addition Eyeqile

•Ukwehlukaniswa & Clumping: Amafayibha ahlanganisiwe adala izindawo ezibuthakathaka zasendaweni, anciphisa amandla okucindezela10%–15%.

•Ukukhubazeka Kokusebenza: Ukuwohloka kunciphangaphezu kuka-15%, okudinga amanzi engeziwe nokwandisa izingozi zesilinganiso samanzi nosimende.

•Amandla Compromise: Ukuphazanyiswa kusimende hydration kunciphisa amandla ebhondi, kube nomthelela ubuqotho besakhiwo.

Isampula Yecala

Ingxube ye-slab yezimboni engu-6 m³ eyenzelwe u-1.5 kg/m³ PP Fiber (9 kg isiyonke)

•I-Under-dosing (0.5 kg/m³): Ukumelana nokuqhekeka kwehla ngo-40%.

•Umthamo oweqile (4 kg/m³): Ukusebenza kwehla ngo-15% ngokulimala koju.

Izinyathelo Zokulungisa Amaphutha Omthamo

Ukulungiswa Kwangaphambi Kokuthela

•Ukulungiswa Kwesilinganiso: Engeza imicu engekho bese uxuba kabusha imizuzu engu-≥5(ungalinge wengeze usimende owomile).

•Ukuthuthukisa Ukuhlakazeka: Yethula i-0.2% ye-polycarboxylate dispersant ukuze uxazulule ukunqwabelana.

•Ukubuyiselwa Kokusebenza: SebenzisaI-JINJI superplasticizerukugcina ukuwohlokangaphandle kokuyekethisa ukwakheka kokuxuba.

Ngemuva Kokuthela (Ngaphambi Kokusetha)

•Ukwabiwa Kabusha Kwemishini: Ukuxuba okunejubane eliphansi (imizuzwana engu-30) ukuze uphinde uhlakaze imicu, ugwema ukuhlanganisana.

•Ukulungiswa Kobuso: Susa ama-clumps abonakalayo ngokusebenzisa i-steel comb raking.

Izixazululo Zangemuva Kokuqina

•Ukuhlola Okungabhubhisi (NDT): Qinisekisa ukufundwa kwesando esiphindayo≥40 MPangokwenele kwesakhiwo.

•Ukuvuselelwa Kwe-Crack: Faka i-epoxy emifantwini>0.3 mmusebenzisa amaphrothokholi e-ASTM C881.

Imihlahlandlela Yezobuchwepheshe Yokusebenza Okulungile

▶ Ibanga Lomthamo Elinconyiwe

*Qaphela: Njalo yenza izixube zesilingo ukuze uqinisekise umthamo ngokusekelwe ekulinganisweni kwesamba, uhlobo lukasimende, kanye nezici zephrojekthi(Lokhu okungenhla kungokwereferensi kuphela).

▶ Ukuxuba Iphrothokholi

•Yethula imicungama-20% ama-aggregateukuvimbela ukuqumba.

•Hlanganisa imizuzwana engaphezu kuka-90ukuqinisekisa ukuhlakazeka okulinganayo.

I-JINJI PP Fiber: Yenzelwe Ukwethembeka

Njengomkhiqizi ohamba phambili wezithasiselo zamakhemikhali zokwakha, i-JINJI CHEMICAL ayikhiqizi kuphelai-cellulose ether,i-polymer powder ehlakazeka kabusha, kodwa futhiHPS, PCE, CMC, PP Fibernjalo njalo. I-JINJI ihlanganisa i-R&D esezingeni eliphezulu nokulawulwa kwekhwalithi okuqinile futhi isebenzela izimboni emhlabeni wonke. Ngokuzibophezela ekusunguleni izinto ezintsha nekhwalithi, i-premium PP Fiber ye-JINJI inikeza:

✅Ukuhlakazeka Okufanayo: Ubuchwepheshe be-anti-clumping bobunikazi buqinisekisa ukusabalalisa okulinganayo.

✅Ukuthuthukiswa Kwesakhiwo: Yandisa amandla okuguquguquka ngo-8–12% futhi inciphisa ububanzi bokuqhekeka ngo-50% (ASTM C1609).

✅Ukuguquguquka: Ifanele izinhlelo zokusebenza ezisakazwa ngaphambili, ezisakazwayo, kanye nokulungisa.

✅Ukusimama: Kwenziwe kusuka ku-100% we-polypropylene egaywe kabusha, ethobela amazinga e-ISO 9001 kanye ne-ASTM C1116.

✅Ukuhambisana Okungeziwe: Ukuhambisana okuhle kakhulu nezithasiselo ezivamile ezifana nokunciphisa amanzi, i-thickener, i-ejenti yokugcina amanzi, i-retarder, i-ejenti yokuvimbela amanzi, njll.
