Polypropylene (PP) Fiber Chopped Strands
KHOOM QHIA TXOG
Cov polypropylene fiber tuaj yeem txhim kho qhov kev sib txuas ntawm cov fiber thiab cement mortar, concrete. Qhov no tiv thaiv kev tawg ntawm cement thiab concrete, tiv thaiv kom tsis txhob muaj kev tawg thiab kev loj hlob ntawm mortar thiab concrete, yog li kom ntseeg tau tias muaj kev sib xyaw ua ke, tiv thaiv kev sib cais thiab cuam tshuam kev tsim cov kab nrib pleb. Cov kev sim qhia tau tias kev sib tov 0.1% ntim ntawm cov fiber, qhov kev tiv thaiv kab nrib pleb ntawm cov concrete mortar yuav nce 70%, ntawm qhov tod tes, nws kuj tuaj yeem txhim kho qhov kev tiv thaiv permeability txog li 70%. Polypropylene fiber (cov xov luv luv ntawm cov denier monofilament zoo heev) raug ntxiv rau cov concrete thaum lub sijhawm sib xyaw. Txhiab tus fibers ib leeg raug faib thoob plaws hauv cov concrete thaum lub sijhawm sib tov tsim cov qauv zoo li matrix.
COV ZOO THIAB COV TXHOJ PAB CUAM

COV LUS QHIA TXOG KEV SIB XYAW
Cov fiber yuav tsum tau ntxiv rau ntawm lub Hoobkas batching txawm hais tias qee zaum qhov no yuav ua tsis tau thiab ntxiv rau ntawm qhov chaw yuav yog tib txoj kev xaiv. Yog tias sib tov ntawm lub Hoobkas batching, cov fibers yuav tsum yog thawj cov khoom sib xyaw, nrog rau ib nrab ntawm cov dej sib tov.
Tom qab ntxiv tag nrho lwm cov khoom xyaw, suav nrog cov dej sib tov uas seem, cov pob zeb yuav tsum tau sib tov tsawg kawg yog 70 lub voj voog ntawm qhov ceev tag nrho kom ntseeg tau tias cov fiber sib xyaw ua ke. Yog tias sib tov rau ntawm qhov chaw, tsawg kawg yog 70 lub voj voog ntawm qhov ceev tag nrho yuav tsum tshwm sim.
