Ma cellulose fiber pakupanga

Ulusi womanga wofunikira ndi: cellulose ether, methyl cellulose (MC), hydroxypropyl methyl cellulose (HPMC), hydroxyethyl cellulose (HEC), carboxymethyl cellulose (CMC), lignin fiber, Cellulose fiber.

Chifukwa cha mawonekedwe a cellulose wokha, monga hydrophilicity yachilengedwe, mphamvu yogwira bwino kwambiri, malo akuluakulu amtundu wa ulusi, komanso kulimba kwambiri ndi mphamvu, etc., atawonjezedwa ku konkire, pansi pamadzi akuwukha ndi mphamvu yakunja, imapanga. Unyinji wogawanika wogawanika bwino wa ulusi wabwino ukhoza kuteteza bwino kuchitika kwa ming'alu yomwe imayambitsidwa ndi shrinkage ya pulasitiki, shrinkage youma ndi kusintha kwa kutentha kwa konkire, komanso kusintha kwambiri makina a konkire.

Ulusi wa cellulose umapangitsa simenti kukhala hydrate kwambiri, imachepetsa kwambiri voids mu konkriti, ndikupanga konkriti yolimba, potero kumathandizira kukana chisanu, kutha kwa madzi, komanso chloride ion permeability ya konkriti, ndikupangitsa konkriti kukhala yolimba bwino.

(1) Anti-scracking zotsatira pa konkire

Ulusi wa cellulose ndi magawo atatu omwe amagawidwa mu konkire, omwe amatha kuchepetsa kupanikizika kwapakati pa nsonga ya ming'alu yaying'ono, kufooketsa kapena kuthetsa kupsinjika kwamphamvu komwe kumachitika chifukwa cha kuchepa kwa konkriti kapena matope, ndikuletsa kuchitika ndi kukulitsa ming'alu yaying'ono.

(2) Kupititsa patsogolo kusasunthika kwa konkire

Kugawa yunifolomu kwa ulusi wa cellulose mu konkire kumapanga dongosolo lothandizira, lomwe limalepheretsa kulekanitsa kwamadzi pamwamba ndi kukhazikika kwa magulu, kumachepetsa magazi a konkire, kumachepetsa kutuluka kwa magazi a konkire, ndipo kumachepetsa kwambiri porosity mu konkire, kotero The impermeability wa konkriti ndi bwino kwambiri.

(3) Sinthani kukana kuzizira kwa konkriti

Chifukwa cha kukhalapo kwa ulusi wa cellulose mu konkriti, imatha kuchepetsa kupsinjika kwa konkriti komwe kumayamba chifukwa cha kuzizira kwambiri, ndikuletsa kufalikira kwa ming'alu yaying'ono.Kuphatikiza apo, chifukwa cha kuwongolera kwa konkriti impermeability, ndizothandizanso kukonza kukana kwake kuzizira.

(4) Sinthani kukana kwamphamvu ndi kulimba kwa konkriti

Ulusi wa cellulose umathandizira kuyamwa ntchito za zigawo za konkire zikakhudzidwa, ndipo chifukwa cha kukana kwa ulusi, pamene konkire imakhudzidwa ndi katundu wokhudzidwa, ulusiwo ukhoza kuteteza kukula kwachangu kwa ming'alu yamkati, kotero kuti ikhoza kupititsa patsogolo. kukana kwamphamvu kwa konkriti ndi kulimba.

(5) Kupititsa patsogolo kukhazikika kwa konkire

Chifukwa chabwino mng'alu kukana zotsatira za mapadi ulusi, zochitika ndi chitukuko cha ming'alu yafupika kwambiri, ndi kuchepetsa porosity mkati amachepetsa dzimbiri ndi malowedwe a chinyezi mu chilengedwe chakunja ndi mankhwala TV, chloride mchere, etc., chifukwa. kwa chiwerengero chachikulu cha ming'alu Kuchepetsedwa, dzimbiri za kulimbikitsa kwakukulu kwa dongosololi kumachepetsedwa, kotero kuti kukhazikika kwa konkire kumakhala bwino kwambiri ndikuwonjezereka.

(6) Kupititsa patsogolo kutentha kwakukulu kwa konkire

Mu konkire, makamaka mu konkire yamphamvu kwambiri, ulusi wa cellulose umawonjezeredwa, chifukwa uli ndi ma monofilaments ambiri omwe amagawidwa mofanana, omwe amapereka magawo atatu mwachisawawa ndipo amapanga maukonde amitundu itatu.Pamene kutentha kwa mkati kwa membala wa konkire wophikidwa ndi moto kumakwera kufika pa 165 Kutentha kukakhala pamwamba pa ℃, ulusi umasungunuka ndikupanga njira zolumikizirana mkati kuti nthunzi yolimba kwambiri ituluke mkati mwa konkire, kotero imatha kupewa kuphulika. m'malo oyaka moto ndikuwongolera kwambiri kukhazikika kwa konkriti.

Anti-seepage ndi anti-crack fiber imatha kupititsa patsogolo mphamvu ndi anti-seepage ntchito ya konkire.Kuphatikizika kwa ukadaulo wa fiber ndi ukadaulo wa konkriti kumatha kupanga ulusi wachitsulo ndi ulusi wopangira zomwe zitha kupititsa patsogolo ntchito ya konkire ndikuwongolera luso la zomangamanga.Yoyamba ndi yoyenera madamu, ma eyapoti, High-liwiro Highway ndi ntchito zina akhoza kusewera odana ndi cracking, odana ndi seepage, zotsatira kukana ndi katundu flexural, yotsirizira akhoza kuteteza oyambirira akulimbana konkire, ndi kuteteza pamwamba pa siteji oyambirira kupanga zinthu za konkriti.Zimakhala ndi zotsatira zabwino popewa kupaka ming'alu, kukonza kusungidwa kwa madzi, kupititsa patsogolo kukhazikika kwa kupanga ndi kukwanira kwa zomangamanga, kukulitsa mphamvu, komanso kumamatira pamwamba.

Ukadaulo wa Fiber umagwiritsidwa ntchito kwambiri m'misewu ya asphalt, konkire, matope, zinthu za gypsum, siponji yamitengo yamatabwa ndi minda ina, misewu ndi malo oimika magalimoto m'malo otentha kwambiri komanso mvula;malo odana ndi skid a misewu yothamanga, njira zamatawuni, ndi misewu yodutsa;mlatho wodutsa mlatho, makamaka mlatho wazitsulo wazitsulo;Madera a Alpine, kuteteza kutentha kwa ming'alu;Magawo odzaza magalimoto pamsewu, katundu wolemetsa komanso magalimoto odzaza kwambiri;Mphambano zamisewu yakutawuni, kokwerera mabasi, mabwalo onyamula katundu, kokwerera madoko.
