Fiber ya Polypropylene (PP Fiber)watuluka ngati chowonjezera chofunikira mu uinjiniya wa konkriti, wodziwika chifukwa cha kuthekera kwakekuonjezera durability,kuchepetsa kupsinjika,ndionjezerani kukana kwamphamvu. Zikaphatikizidwa bwino, zolimbitsa thupi zazing'onozi zimakhala ngati zinthu zokhazikika zogawika, kutsekereza ming'alu yaying'ono ndikugawanso kupsinjika kuti kulimbikitse kukhulupirika.

Komabe, mlingo wosayenera—kaya wochulukira kapena wosakwanira—ukhoza kusokoneza magwiridwe antchito, kugogomezera kufunika kwa kugwiritsira ntchito molondola.

Udindo wa PP Fiber mu Konkire Mix

PP Fiber imapereka maubwino atatu oyambira:

1. Kuchepetsa Mng'alu: Kumachiritsira koyambirira, kumalepheretsa kung'ambika kwa pulasitiki potsekereza ming'alu yaying'ono, ndikuletsa kufalikira kwawo kukhala zolakwika zowonekera.

2. Kulimbitsa Thupi: Pakuwongolera ductility, PP Fiber imakulitsa mphamvu ya konkriti kuti itenge mphamvu ndi kutopa, kuchepetsa ziwopsezo zosweka.

3. Durability Augmentation: Kupyolera mu kudzaza zopanda kanthu ndi kukonza ming'alu, kumachepetsa kuloleza, kuteteza madzi kuti asalowe, kuwonongeka kwa mankhwala, ndi kuwonongeka kwa rebar.

Zotsatira za Non-Fiber Concrete

♦ Pulasitiki Shrinkage Cracking

Popanda PP Fiber: Kuchuluka kwa chinyezi kumapangitsa kuti pakhale ming'alu (0.3-2 mm m'lifupi) mkati mwa maola 24, kusokoneza kukhulupirika kwa pamwamba.
Ndi PP Fiber: Kuyanjana kwa Fiber-matrix kumachepetsa kusweka koyambirirakuposa 70%.

♦ Kusokonekera kwa Resistance Deficiency

Konkire yopanda mphamvu: Imawonetsa kulephera kwamphamvu pansi pa 30 J mphamvu yamphamvu (mwachitsanzo, kugundana kwa forklift kapena kutsitsa kwamphamvu).
Konkire yowonjezera fiber: Kuchuluka kwa mphamvu kumawonjezeka2-4 nthawi, kuchepetsa chiopsezo cha fracture.

♦ Kuwonongeka Kwambiri Kwachangu

Popanda PP Fiber: Ming'alu yosalamulirika imathandizira kulowa kwa madzi ndi kloridi, kufulumizitsa dzimbiri la rebar ndi kuphulika kwapamtunda.
Ndi PP Fiber: Kuwongolera mwamphamvu (60%, kuwonjezera moyo wautumiki ndi8-12 zakam'malo ovuta.

Kufananiza kwa Magwiridwe Ochulukira

Zambiri zotsatirazi zikuwonetsa phindu lowoneka la PP Fiber pamakina ofunikira:

Kuopsa kwa Mlingo Wosayenera wa PP Fiber

1. Kusakwanira kwa Fiber Addition

•Crack Control Kulephera: Kulimbitsa kosakwanira kumapangitsa kuti ming'alu ya shrinkage ikulitsidwe40%(mwachitsanzo, mu mapulogalamu a slab).

•Kuchepa kwa Kagwiridwe ka Ntchito: Mphamvu yolemetsa imatsika30% -50%, kukulitsa chiwopsezo cha kuchuluka kwa magalimoto pamsewu kapena zivomezi.

•Kuthamanga kwa Corrosion: Kuchuluka kwa chloride kumakwera60%m'malo am'madzi, kusokoneza chitetezo cha rebar.

2. Zowonjezera Fiber Zowonjezera

•Kupatukana & Clumping: Ulusi wophatikizika umapanga madera ofooka, amachepetsa mphamvu zopondereza10% -15%.

•Kuwonongeka kwa Ntchito: Kutsika kumachepakuposa 15%, kufunikira kwa madzi owonjezera ndi kuwonjezereka kwa chiwopsezo cha madzi ndi simenti.

•Mphamvu Compromise: Kusokoneza simenti hydration kumachepetsa mphamvu zomangira, zomwe zimakhudza kukhulupirika kwadongosolo.

Chitsanzo

Kusakaniza kwa slab kwa 6 m³ kwa mafakitale opangira 1.5 kg/m³ PP Fiber (9 kg yonse)

•Kuchepetsa mlingo (0.5 kg/m³): Kukana kwa mng'alu kumatsika ndi 40%.

•Kuchulukitsa (4 kg/m³): Kugwira ntchito kumatsika ndi 15% ndi vuto la zisa.

Njira Zowongolera Zolakwika za Mlingo

Zosintha Zothira Zisanayambe

•Kuwongolera Mlingo: Onjezani ulusi wosowa ndikusakanizanso kwa mphindi ≥5(osawonjezera simenti youma).

•Kupititsa patsogolo Kubalalika: Yambitsani 0.2% polycarboxylate dispersant kuti muthetse kugwa.

•Kubwezeretsa Ntchito: GwiritsaniJINJI superplasticizerkusunga kugwapopanda kusokoneza kapangidwe kakusakaniza.

Kuthira Pambuyo (Musanakhazikike)

•Kugawanso Kwamakina: Kusakanikirana kocheperako (masekondi 30) kuti mubalenso ulusi, kupewa kukhazikika.

•Kukonzanso Pamwamba: Chotsani zitsulo zowoneka bwino pogwiritsa ntchito chitsulo chachitsulo.

Mayankho a Post-Hardening

•Kuyesa Kopanda Kuwononga (NDT): Onetsetsani kuti nyundo ikuwerengedwanso≥40 MPapakukwanira kwamapangidwe.

•Kukonzanso kwa Crack: Lowetsani epoxy mu ming'alu> 0.3 mmpogwiritsa ntchito ma protocol a ASTM C881.

Malangizo aukadaulo kuti mugwire bwino ntchito

▶ Mlingo wovomerezeka

*Zindikirani: Nthawi zonse muzichita zosakaniza zoyeserera kuti mutsimikizire mlingo kutengera kuchuluka kwa simenti, mtundu wa simenti, ndi mafotokozedwe a polojekiti.(Zomwe zili pamwambazi ndi zongonena).

▶ Kusakaniza Protocol

•Yambitsani ulusindi 20% ya aggregateskuteteza kugwa.

•Sakanizani kwa masekondi opitilira 90kuonetsetsa kubalalitsidwa homogeneous.

JINJI PP Fiber: Yopangidwira Kudalirika

Monga opanga otsogola opanga zowonjezera zamankhwala, JINJI CHEMICAL sikuti amangopangacellulose ether,redispersible polima ufa, komansoHPS, PCE, CMC, PP CHIKWANGWANIndi zina zotero. JINJI imaphatikiza R&D yotsogola ndikuwongolera bwino kwambiri ndipo imagwira ntchito m'mafakitale padziko lonse lapansi. Ndi kudzipereka ku luso ndi khalidwe, JINJI umafunika PP Fiber amapereka:

✅Kubalalika kwa Uniform: Tekinoloje yotsutsana ndi clumping imatsimikizira kugawa kofanana.

✅Kupititsa patsogolo Kapangidwe: Imawonjezera mphamvu yosinthika ndi 8-12% ndipo imachepetsa ming'alu ndi 50% (ASTM C1609).

✅Kusinthasintha: Yoyenera ku precast, kuponyedwa-malo, ndi kukonza mapulogalamu.

✅Kukhazikika: Wopangidwa kuchokera ku 100% recycled polypropylene, yogwirizana ndi ISO 9001 ndi ASTM C1116 miyezo.

✅Kuphatikizana kowonjezera: Kugwirizana kwabwino kwambiri ndi zowonjezera wamba monga chochepetsera madzi, thickener, chosungira madzi, retarder, woletsa madzi, etc.
