Polypropylene Fiber (PP Fiber)yakabuda sechinhu chakakosha chekuwedzera muinjiniya yekongiri, inozivikanwa nekugona kwayokuwedzera kusimba,kuderedza kuputika,uyekunatsiridza kukanganisa kupikisa. Kana yakabatanidzwa nemazvo, aya madiki-reinforcements anoita seakagovaniswa tensile zvinhu, bhiridha madiki macracks uye kugoverazve kushushikana kuti iwedzere kutendeseka kwechimiro.

Nekudaro, dosi isina kufanira — ingave yakawandisa kana isina kukwana — inogona kukanganisa mashandiro, zvichisimbisa kukosha kwekushandisa chaiko.

Basa rePP Fiber muConcrete Mix

PP Fiber inopa matatu epakati einjiniya mabhenefiti:

1. Crack Mitigation: Panguva yekurapa kwekutanga, inodzivirira kuputika kwepurasitiki nekuvhara madiki madiki-diki, kudzivirira kupararira kwawo kuita hurema hunooneka.

2. Kuwedzera Kusimba: Nekuvandudza ductility, PP Fiber inokwidziridza kugona kwekongiri kutora maitiro uye kuneta mitoro, kuderedza brittle kutyoka njodzi.

3. Durability Augmentation: Kuburikidza nekuzadza-isina uye kukwenenzverwa kwekupwanyika, inoderedza kupindirana, kuchengetedza kubva pakupinda kwemvura, kemikari corrosion, uye kuparara kwerebar.

Mhedzisiro yeNon-Fiber Concrete

♦ Plastic Shrinkage Cracking

Mukushaikwa kwePP Fiber: Kukurumidza kunyunguduka kwehunyoro kunokonzera kutsemuka kwepamusoro (0.3-2 mm upamhi) mukati meawa makumi maviri nemana, zvichikanganisa kutendeseka kwepasi.
NePP Fiber: Kudyidzana kweFiber-matrix kunoderedza kutanga-nhanho kupwanyapamusoro pe70%.

♦ Impact Resistance Deficiency

Kongiri isina kusimbiswa: Inoratidza kutadza kusimba pasi pe30 J simba rekuita (semuenzaniso, kudhumhana kweforklift kana kurodha zvine simba).
Fiber-yakasimbiswa kongiri: Simba rekutora simba rinowedzera2-4 nguva, kuderedza njodzi dzekutyoka.

♦ Yakawedzera Kusimba Kuderera

Pasina PP Fiber: Kutsemuka kusingadzoreki kunoita kuti mvura uye chloride ipinde, inomhanyisa kuparara kwerebar uye kuparara kwepasi.
NePP Fiber: Tight crack control (60%, kuwedzera hupenyu hwebasa kuburikidza8-12 makoremunzvimbo dzakaoma.

Quantitative Performance Kuenzanisa

Iyo inotevera yehuwandu data inoratidza mabhenefiti anobatika ePP Fiber mune akakosha ekuita metrics:

Njodzi dzeIsina Kufanira PP Fiber Dosage

1. Insufficient Fiber Addition

•Mutswe Kudzora Kukundikana: Kusasimba kwekusimbisa kunobvumira shrinkage kuputika kuwedzera40%(semuenzaniso, mune slab application).

•Impact Performance Decline: Dynamic load capacity inodonha30%–50%, kuwedzera kusagadzikana kune traffic kana mitoro yekudengenyeka kwenyika.

•Corrosion Acceleration: Chloride ingress rates inokwira ne60%munzvimbo dzemugungwa, kukanganisa kuchengetedza rebar.

2. Yakawandisa Fiber Addition

•Segregation & Clumping: Agglomerated fibers inogadzira nzvimbo dzisina kusimba dzenzvimbo, kuderedza kumanikidza simba ne10%–15%.

•Kusagadzikana Kwekushanda: Kudonha kunoderera nezvinopfuura 15%, zvichida mvura yakawedzerwa uye kuwedzera njodzi dzechiyero chemvura-simende.

•Simba Compromise: Kupindira ne simenti hydration inoderedza simba rebhondi, inokanganisa kutendeseka kwechimiro.

Nyaya Yemuenzaniso

A 6 m³ indasitiri slab musanganiswa wakagadzirirwa 1.5 kg/m³ PP Fiber (9 kg yakazara)

•Under-dosing (0.5 kg/m³): Kuramba kwemutswe kunoderera ne40%.

•Kuwedzera-dosing (4 kg/m³): Kusagona kushanda kunoderera ne15% nekukanganisika mumizinga.

Kugadzirisa Matanho ekukanganisa Dosage

Pre-Kudurura Kugadziriswa

•Kugadzirisa Dosage: Wedzera zvisipo fiber uye remix kwe ≥5 maminetsi(usambowedzera simende yakaoma).

•Kuparadzira Kuwedzera: Sungisa 0.2% polycarboxylate dispersant kugadzirisa clumping.

•Workability Restoration: ShandisaJINJI superplasticizerkuchengetedza kudonhapasina kukanganisa musanganiswa dhizaini.

Post-Kudurura (Kusati kwaiswa)

•Mechanical Redistribution: Kunyorova kwakaderera-kumhanya kusanganisa (30 masekonzi) kuparadzira zvakare mafibhi, kudzivirira aggregate kugadzirisa.

•Surface Remediation: Bvisa masumbu anooneka kuburikidza nesimbi comb raking.

Post-Hardening Solutions

•Kuyedzwa Kusina Kuparadza (NDT): Ita shuwa rebound kuverenga sando≥40 MPakuitira kukwana kwemaitiro.

•Crack Rehabilitation: jekiseni epoxy mumitswe>0.3 mmuchishandisa ASTM C881 protocol.

Mirayiridzo yeTekinoroji yeKushanda Kwakakwana

▶ Inokurudzirwa Dosage Range

*Cherechedza: Gara uchiitisa musanganiswa wekuedzwa kuti usimbise dosage zvichibva pane aggregate gradation, simende mhando, uye purojekiti yakatarwa.(Zviri pamusoro ndezvekureva chete).

▶ Kusanganisa Protocol

•Kusuma fibersne20% yezvikamukudzivirira clumping.

•Sanganisa kweanopfuura masekonzi makumi mapfumbamwekuve nechokwadi chekupararira kwehomogeneous.
