Zotsatira za Fiberglass pa Kukaniza Kokokoloka kwa Konkire Wopangidwanso

Mphamvu ya magalasi a fiberglass pakukana kukokoloka kwa konkire yobwezerezedwanso (yopangidwa kuchokera kumagulu a konkriti obwezerezedwanso) ndi mutu womwe uli ndi chidwi kwambiri ndi sayansi ya zida ndi zomangamanga. Ngakhale konkire yobwezerezedwanso imapereka zabwino zachilengedwe komanso zobwezeretsanso zinthu, mawonekedwe ake amakina ndi kulimba kwake (mwachitsanzo, kukana kukokoloka) nthawi zambiri zimakhala zotsika poyerekeza ndi konkriti wamba. Fiberglass, mongakulimbikitsa zinthu, ikhoza kupititsa patsogolo ntchito ya konkire yobwezerezedwanso kudzera munjira zakuthupi ndi zamankhwala. Pano pali kusanthula mwatsatanetsatane:

1. Katundu ndi Ntchito zaFiberglass

Fiberglass, inorganic non-metal material, imakhala ndi zotsatirazi:
Kulimba kwamphamvu kwambiri: Kulipiritsa mphamvu yotsika ya konkriti.
Kukana dzimbiri: Kumakana kukhudzidwa ndi mankhwala (monga ma chloride ayoni, sulfates).
Kulimbitsa ndi kukana ming'alu**: Imatsekereza ma microcracks kuti achedwetse kufalikira ndikuchepetsa kupenya.

2. Durability Zofooka za Recycled Concrete

Zophatikiza zobwezerezedwanso zokhala ndi phala lotsalira la simenti pamalopo zimatsogolera ku:
Weak interfacial transition zone (ITZ): Kusalumikizana bwino pakati pa zowumbidwanso ndi phala latsopano la simenti, kupanga njira zolowera.
Kusawotchera: Zinthu zokokoloka (monga Cl⁻, SO₄²⁻) zimaloŵa mosavuta, kuchititsa dzimbiri lachitsulo kapena kuwonongeka kwakukulu.
Kusasunthika bwino kwa madzi oundana: Kuwonjezeka kwa ayezi mu pores kumapangitsa kung'ambika ndi kuphulika.

3. Njira za Fiberglass mu Kupititsa patsogolo Kukaniza Kukokoloka

(1) Zolepheretsa Mwathupi
Kuletsa mng'alu: Ulusi wobalalika wofanana umatsekereza ma microcracks, kutsekereza kukula kwawo ndikuchepetsa njira zokokoloka.
Kulumikizana bwino: Ulusi umadzaza pores, kutsitsa porosity ndikuchepetsa kufalikira kwa zinthu zovulaza.

(2) Kukhazikika kwa Chemical
Magalasi a fiberglass osamva alkali(mwachitsanzo, galasi la AR): Ulusi wothiridwa pamwamba umakhala wokhazikika m'malo okhala ndi alkali wambiri, kupewa kuwonongeka.
Kulimbitsa kwa mawonekedwe: Kumangirira kolimba kwa fiber-matrix kumachepetsa zolakwika mu ITZ, kuchepetsa ziwopsezo zakukokoloka kwanuko.

(3) Kukaniza Mitundu Yomwe Ikukokoloka
Kukana kwa ayoni wa chloride: Kuchepa kwa ming'alu kumachepetsa Cl⁻ kulowa, kuchedwetsa dzimbiri lachitsulo.
Sulfate attack resistance: Kuponderezedwa kwa mng'alu kumachepetsa kuwonongeka kwa sulphate crystallization ndi kukulitsa.
Kukhazikika kwa kuzizira: Kusinthasintha kwa Fiber kumatengera kupsinjika komwe kumachitika chifukwa cha ayezi, kumachepetsa kuphulika.

4. Zinthu Zofunika Kwambiri

Fiber mlingo: Mulingo woyenera kwambiri ndi 0.5% -2% (ndi voliyumu); ulusi wochulukirachulukira umapangitsa kuphatikizika ndikuchepetsa kuphatikizika.
Kutalika kwa ulusi ndi kubalalitsidwa: Ulusi wautali (12-24 mm) umapangitsa kuti ukhale wolimba koma umafunika kugawa mofanana.
Ubwino wa zophatikiza zobwezerezedwanso: Kuyamwa kwambiri kwamadzi kapena matope otsalira kumafooketsa kugwirizana kwa fiber-matrix.

5. Zotsatira za Kafukufuku ndi Mapeto Othandiza

Zotsatira zabwino: Kafukufuku wambiri amasonyeza kuti ndizoyeneragalasi la fiberglassKuphatikizana kumapangitsa kuti zisawonongeke, kukana kwa chloride, ndi kukana kwa sulfate. Mwachitsanzo, magalasi a fiberglass 1% amatha kuchepetsa kufalikira kwa chloride ndi 20% -30%.
Kuchita kwanthawi yayitali: Kukhalitsa kwa ulusi m'malo amchere kumafuna chidwi. Zopaka zolimbana ndi alkali kapena ulusi wosakanizidwa (mwachitsanzo, zokhala ndi polypropylene) zimakulitsa moyo wautali.
Zolepheretsa: Zophatikiza zobwezerezedwanso bwino (mwachitsanzo, porosity kwambiri, zonyansa) zitha kuchepetsa phindu la fiber.

6. Malangizo a Ntchito

Zochitika zoyenera: Malo am'madzi, dothi lamchere, kapena zomanga zomwe zimafuna konkriti yokhazikika yokhazikika.
Sakanizani kukhathamiritsa: Yesani mulingo wa fiber, chiŵerengero chobwezerezedwanso chowonjezera, ndi ma synergies ndi zowonjezera (monga silika fume).
Kuwongolera kwabwino: Onetsetsani kuti fiber imwazikika mofanana kuti mupewe kuphatikizika pakusakaniza.

Chidule

Fiberglass imakulitsa kukana kukokoloka kwa konkire yobwezerezedwanso kudzera pakulimba kwakuthupi komanso kukhazikika kwamankhwala. Kugwira ntchito kwake kumadalira mtundu wa ulusi, mlingo, ndi mtundu wobwezerezedwanso. Kafukufuku wamtsogolo akuyenera kuyang'ana kwambiri kukhazikika kwanthawi yayitali komanso njira zopangira zotsika mtengo kuti zithandizire ntchito zazikulu zaumisiri.
