Cellulose fiber hauv kev tsim kho

Cov khoom siv tseem ceeb yog: cellulose ether, methyl cellulose (MC), hydroxypropyl methyl cellulose (HPMC), hydroxyethyl cellulose (HEC), carboxymethyl cellulose (CMC), lignin fiber, Cellulose fiber.

Vim yog cov yam ntxwv ntawm cellulose nws tus kheej, xws li ntuj hydrophilicity, zoo heev gripping quab yuam, loj loj fiber ntau thaj chaw, thiab siab toughness thiab lub zog, thiab lwm yam., tom qab muab ntxiv rau pob zeb, nyob rau hauv qhov kev txiav txim ntawm dej soaking thiab sab nraud quab yuam, nws tsim. Ib tug loj tus naj npawb ntawm cov sib npaug zoo fibers tuaj yeem tiv thaiv qhov tshwm sim ntawm cov kab nrib pleb tshwm sim los ntawm cov yas shrinkage, qhuav shrinkage thiab kub hloov ntawm cov pob zeb, thiab txhim kho cov cuab yeej ntawm cov pob zeb.

Cellulose fibers ua rau cov cement hydrate ntau dua, txo cov voids hauv cov pob zeb, thiab ua kom cov pob zeb denser, yog li txhim kho Frost tsis kam, dej permeability, thiab chloride ion permeability ntawm cov pob zeb, thiab muab cov pob zeb ua kom zoo dua qub.

(1) Anti-cracking nyhuv ntawm pob zeb

Cellulose fibers yog peb-dimensionally faib rau hauv pob zeb, uas tuaj yeem txo qhov kev ntxhov siab ntawm qhov kawg ntawm micro-cracks, tsis muaj zog lossis tshem tawm cov kev ntxhov siab tensile los ntawm shrinkage ntawm pob zeb lossis mortar, thiab tiv thaiv qhov tshwm sim thiab nthuav dav ntawm micro-cracks.

(2) Txhim kho qhov impermeability ntawm pob zeb

Kev faib tawm ntawm cov cellulose fibers hauv cov pob zeb ua ib qho kev txhawb nqa, uas cuam tshuam cov dej sib cais thiab kev sib haum xeeb ntawm cov pob zeb, txo cov ntshav los ntawm cov pob zeb, txo cov ntshav los ntawm cov pob zeb, thiab txo cov porosity hauv pob zeb, yog li lub impermeability ntawm pob zeb ua tau zoo heev.

(3) Txhim kho qhov khov-thaw tsis kam ntawm pob zeb

Vim tias muaj cov cellulose fibers hauv cov pob zeb, nws tuaj yeem txo qhov concentration ntawm tensile kev nyuaj siab hauv pob zeb los ntawm ntau lub voj voog khov-thaw, thiab tiv thaiv kev nthuav dav ntxiv ntawm micro-cracks. Tsis tas li ntawd, vim kev txhim kho ntawm cov pob zeb impermeability, nws kuj yog qhov zoo los txhim kho nws cov khov-thaw tsis kam.

(4) Txhim kho qhov cuam tshuam thiab toughness ntawm pob zeb

Cellulose fibers pab kom nqus tau cov haujlwm ntawm cov khoom vaj khoom tsev thaum lawv raug cuam tshuam, thiab vim muaj cov nyhuv tawg ntawm cov fibers, thaum cov pob zeb raug cuam tshuam, cov fibers tuaj yeem tiv thaiv kev nthuav dav ntawm cov kab nrib pleb, yog li nws tuaj yeem txhim kho tau zoo. qhov cuam tshuam tsis kam ntawm pob zeb thiab toughness.

(5) Kev txhim kho ntawm kev ua vaj tse durability

Vim tias qhov ua tau zoo ntawm kev ua haujlwm ntawm cov cellulose fibers, qhov tshwm sim thiab kev loj hlob ntawm cov kab nrib pleb raug txo kom tsawg, thiab qhov txo qis hauv cov porosity slows tus corrosion thiab nkag mus ntawm noo noo nyob rau hauv ib puag ncig sab nraud thiab tshuaj lom neeg, chloride ntsev, thiab lwm yam. mus rau qhov loj ntawm cov kab nrib pleb Txo, qhov corrosion ntawm lub ntsiab qhov cuab lub zog ntawm cov qauv yog txo, thiaj li hais tias lub durability ntawm pob zeb yog zoo heev txhim kho thiab txhim khu kev qha.

(6) Kev txhim kho ntawm qhov kub thiab txias tsis kam ntawm cov pob zeb

Nyob rau hauv cov pob zeb, tshwj xeeb tshaj yog nyob rau hauv high-zog pob zeb, cellulose fiber yog ntxiv, vim hais tias nws muaj ib tug loj tus naj npawb ntawm uniformly faib fiber ntau monofilaments, uas nthuav tawm peb-dimensional random faib thiab tsim ib tug peb-dimensional network qauv. Thaum qhov kub thiab txias ntawm cov nplaim hluav taws kub ntawm cov neeg ua vaj tse nce mus txog 165 Thaum qhov kub siab tshaj ℃, cov fibers yaj thiab tsim cov kev sib txuas sab hauv kom muaj zog siab zog kom khiav tawm ntawm sab hauv ntawm cov pob zeb, yog li nws tuaj yeem ua kom tsis txhob tawg. nyob rau hauv ib puag ncig hluav taws thiab ua kom zoo dua qub ntawm cov pob zeb.

Anti-seepage thiab anti-crack fiber ntau tuaj yeem txhim kho lub zog thiab tiv thaiv kev ua haujlwm ntawm cov pob zeb. Kev sib xyaw ntawm cov tshuab fiber ntau thiab kev siv tshuab ua vaj tse tuaj yeem txhim kho steel fibers thiab hluavtaws fibers uas tuaj yeem txhim kho kev ua tau zoo ntawm cov pob zeb thiab txhim kho kev tsim vaj tsev zoo. Lub qub yog tsim rau dams, tshav dav hlau, high-speed Highway thiab lwm yam dej num muaj peev xwm ua si anti-cracking, anti-seepage, cuam tshuam tsis kam thiab flexural zog, lub tom kawg tuaj yeem tiv thaiv kev tawg thaum ntxov ntawm pob zeb, thiab tiv thaiv qhov chaw nyob rau theem pib ntawm kev tsim cov khoom vaj khoom tsev. Nws muaj cov txiaj ntsig zoo ntawm kev tiv thaiv txheej txheej tawg, txhim kho dej tuav, txhim kho kev ruaj khov thiab kev tsim kho kom haum, ua kom muaj zog, thiab txhim kho adhesion rau saum npoo.

Fiber technology yog dav siv nyob rau hauv asphalt txoj kev, qhob, mortar, gypsum khoom, ntoo pulp daim txhuam cev thiab lwm yam teb, txoj kev nto thiab chaw nres tsheb nyob rau hauv high-temperature thiab rainy cheeb tsam; anti-skid nto ntawm expressways, nroog expressways, thiab arterial txoj kev; choj lawj pavement, tshwj xeeb tshaj yog steel choj lawj pavement; alpine cheeb tsam, tiv thaiv kub shrinkage tawg; Cov tsheb loj loj, cov khoom hnyav hnyav thiab cov tsheb thauj khoom ntau dhau; Kev sib tshuam ntawm txoj kev hauv nroog, chaw nres tsheb npav, chaw thauj khoom, chaw nres nkoj terminals.
