Lub lis piam uas hloov li cas kuv pom Shotcrete
Kuv tseem nco qab hu. Nws yog hnub Friday tav su, thiab tus thawj tswj xyuas qhov project tau frantic. Ib txoj haujlwm tunneling tau poob qab lub sijhawm. Cov steel fiber reinforced shotcrete tau ua rau qeeb-clogging hoses, hnav tawm nozzles, thiab cov neeg coob tau poob siab. Lawv xav tau kev daws, thiab lawv xav tau ceev ceev. Hnub so, peb tau khiav qhov kev sim puv nrog PP fibrillated fiber ntau rau kev siv tshuaj tua kab mob. Qhov txawv yog tam sim ntawd. Qhov sib tov ntws zoo dua. Rov qab poob. Thiab qhov project tau rov qab los. Qhov kev paub ntawd tau qhia kuv ib yam tseem ceeb: tus txoj cai kev xaiv fiber ntau tuaj yeem txuag tau ntau dua li nyiaj-nws tuaj yeem txuag koj lub sijhawm thiab koj lub siab.
Vim li cas PP Fibrillated Fiber Tsim nyog saib ob
Cia peb hla lub suab nrov. Steel fibers tau ib txwm mus-mus rau qhov hauv ob sab phlu thiab nqes hav stabilization. Tab sis lawv tsis yog ib qho kev xaiv ntse. PP yog fibrillated fiber ntau rau kev siv tshuaj tua kab mob muab cov txiaj ntsig tshwj xeeb uas hais ncaj qha rau cov neeg ua haujlwm mob taub hau txhua hnub. Cov fibers yog engineered nrog ib tug network ntawm me me fibrils uas mechanically thauj tog rau nkoj rau hauv cov cement matrix. Lawv tsis xeb. Lawv yog lub teeb yuag. Thiab lawv zoo heev txhim kho cov khoom toughness thiab tawg tsis kam.
Dab tsi ua rau nws txawv ntawm Hlau?
Hlau muaj zog. PP yog fibrillated fiber ntau yog ntse. Xav txog corrosion. Nyob rau hauv ib qho chaw ntub dej-zoo li lub qhov los yog qhov chaw mining-steel fibers tuaj yeem corrode, ua rau spalling thiab structural degradation nyob rau lub sijhawm. Polypropylene fibers yog chemically inert. Lawv luag ntxhi. Lawv kuj txo qhov hnyav tag nrho ntawm kev sib tov, uas yog qhov tseem ceeb thaum koj txau saum taub hau. Koj cov neeg ua haujlwm txhais caj npab yuav ua tsaug rau koj.
Koj Daim Ntawv Qhia 5-Kauj rau Kev Siv PP Fibrillated Fiber hauv Shotcrete
Qhov no tsis yog theoretical. Nov yog koj ua li cas, kauj ruam los ntawm kauj ruam, ntawm koj txoj haujlwm tom ntej.
Kauj ruam 1: Txiav txim siab koj tus nqi npaum li cas
Dosage yog txhua yam. Rau feem ntau ntawm kev siv cov cuab yeej txhawb nqa, koj yuav ua hauj lwm nyob rau hauv ib tug ntau yam ntawm 0.5 rau 1.5 kilogram ib cubic meter. Pib qis thiab sim. Rau lub qhov av thawj liner qhov twg pob zeb tawg yog ib qho kev txhawj xeeb, lean mus rau qhov kawg siab dua (1.2-1.5 kg/m³). Rau ib kho shotcrete txheej ntawm ib tug choj, 0.6 kg/m³ tej zaum yuav txaus los tswj cov yas shrinkage tawg. Tsis txhob twv. Khiav lub vaj huam sib luag sim. Xyuas qhov flexural toughness.
Kauj ruam 2: Xaiv Koj Cov Txheej Txheem-Wet-Mix lossis Dry-Mix
PP yog fibrillated fiber ntau ua si zoo nrog ob leeg. Hauv ib kev sib xyaw ntub dej, ntxiv cov fibers rau lub tov khoom ntawm cov nroj tsuag batching. Muab lawv nrog cov aggregates thiab cement ua ntej ntxiv dej. Qhov no ua kom muaj kev faib tawm tsis sib xws. Rau qhuav-mix shotcrete, Ntxiv cov fibers rau qhuav sib tov ntawm lub nozzle los yog nyob rau hauv lub pre-dampener. Qhov tseem ceeb yog kom tsis txhob clumping. Siv lub hnab kom raug. Pre-disperse cov fibers yog ua tau.
Kauj ruam 3: Kho Koj Cov Kev Tsim Kho Mix
Fibers hloov rheology ntawm cov pob zeb tshiab. Tsis txhob tsis quav ntsej qhov no. Tej zaum koj yuav tau nce koj cov ntsiab lus cementitious me ntsis (los ntawm 5-10 kg/m³) tswj kev ua haujlwm. High-range dej reducer (superplasticizer) feem ntau yuav tsum tau khaws cov slump qhov twg koj xav tau. Koj lub hom phiaj yog kev sib xyaw ua ke tab sis tsis nplaum. Ib tug zoo-tsim fiber-reinforced mix yuav twj smoother thiab tsuag ntau uniformly.
Kauj ruam 4: Fine-Tune Koj Cov Khoom Siv rau Pumpability thiab Rebound
Qhov no yog qhov kev paub tseem ceeb. PP fibrillated fibers txhim kho Pumpability piv rau steel fibers vim lawv sib zog thiab tsawg abrasive. Txawm li cas los, lawv tuaj yeem cuam tshuam rebound yam ntxwv. Koj tuaj yeem pom qhov nce me ntsis hauv qhov rov qab yog tias koj qhov sib tov qhuav dhau lawm. Qhov kho? Ntxiv 2-3% dej ntau (los ntawm qhov hnyav ntawm cement) los yog nce qhov feem pua zoo tag nrho. Kho koj lub nozzle cua siab. Khaws lub nozzle perpendicular rau saum npoo. A 10% rov qab zoo. Yog koj pom 20%, ib yam dab tsi tawm.
Kauj ruam 5: Kuaj, Kuaj, thiab sim dua
Koj xav tau cov ntaub ntawv, tsis xav. Siv ASTM C 1116 1 (Standard Specification rau Fiber-Reinforced Concrete) raws li koj phau ntawv qhia. Kev lag luam tus qauv rau kev txhaj tshuaj yog EFNARC vaj huam sib luag xeem. Cam khwb cia ib tug flexural beam los yog ib tug square vaj huam sib luag. Ntsuas qhov toughness. Muab piv rau koj cov hlau fiber ntau hauv paus. Cov lej yuav hais rau lawv tus kheej. PP fibrillated fiber ntau tsis tu ncua muab qhov sib npaug lossis zoo dua tom qab tawg lub zog nqus, tsis muaj kev pheej hmoo corrosion.
Daim ntawv thov tiag-lub ntiaj teb qhov twg Fiber Shines
Cia peb tham txog qhov twg koj yuav tsum siv tag kis.
- Tunneling thiab Mining: Pob zeb txhawb, thawj cov ntaub ntawv. Kev cuam tshuam siab thiab kev puas tsuaj yuav tsum tau ua. PP fiber absorbs zog zoo.
- Slope Stabilization: Nyias txheej hla av los yog pob zeb. Cov fiber ntau txo cov yas shrinkage cracking hauv cov tseem ceeb ua ntej 24 teev.
- Kho thiab Rehabilitation: Overlays ntawm cov choj, chaw nres tsheb cov qauv, los yog industrial floors. Tsis muaj corrosion txhais tau tias tsis muaj yav tom ntej staining los yog spalling.
- Cov pas dej da dej thiab cov dej tso dej: Impermeability thiab tawg tswj. Cov fiber ntau txo qhov kev pheej hmoo ntawm kev xau.
Hais txog Elephant hauv Chav: Adhesion
Ib qho kev txhawj xeeb feem ntau yog seb puas ntxiv cov hluavtaws fibers tsis muaj zog rau daim ntawv cog lus rau lub substrate. Xov xwm zoo: nws tsis. Cov fibers yog uniformly faib. Lawv tsis ntab rau saum npoo zoo li qee qhov sib xyaw ua ke. Kev ntsuam xyuas dav dav qhia tau tias tus adhesion zog rau lub substrate tseem tsis cuam tshuam. Qhov tseeb, kev txhim kho tawg tawg feem ntau ua rau kev ua tau zoo tag nrho ntawm daim ntawv cog lus.
Nqi-zoo? Cia peb ua lej
Nqe ib kilogram yog siab dua rau PP fibrillated fiber ntau piv rau hlau. Tab sis lub nqi-zoo lwm txoj kev sib cav tuav thaum koj saib tag nrho daim duab. Tsawg hnav ntawm koj lub twj tso kua mis thiab hoses. Tsawg downtime rau kev kho khoom siv. Tsis xav tau kev txo nqi corrosion. Cov khoom siv sib dua. Thaum koj xam tag nrho cov nqi siv (khoom + kev ua haujlwm + khoom siv + pheej hmoo), PP fiber ntau yeej txiav txim siab, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig txhoj puab heev.
Koj Mus Ntxiv
Koj tau nyeem cov kauj ruam. Koj nkag siab cov txiaj ntsig. Tam sim no nws yog lub sijhawm los ua. Tsis txhob tos kom muaj kev kub ntxhov zoo li hnub Friday tav su hu kuv tau txais. Order ib sim batch ntawm PP fibrillated fiber ntau rau kev siv tshuaj tua kab mob. Khiav lub vaj huam sib luag. Ntsuas cov txiaj ntsig. I am confident you will see the difference. Start with a dosage of 1.0 kg/m³, ua raws li cov kauj ruam saum toj no, and see for yourself. Your crew, your schedule, and your budget will be better for it.
