Kukhudzika kwa fiberglass pa kukana kwa konkriti yobwezeredwa

Mphamvu ya fiberglass pa kukomoka konkriti yobwezeretsedwanso (yopangidwa kuchokera konkriti yobwezerezedwanso) ndi mutu wofunika kwambiri pazinthu zamagulu ndi ukadaulo. Ngakhale konkriti yobwezerezedwanso imapereka phindu la chilengedwe komanso zobwezeretsanso zothandizira komanso kulimba (mwachitsanzo, kukana) nthawi zambiri kumakhala kotsika kwa konkriti wamba. Fiberglass, mongaKulimbikitsa Zinthu, imatha kupititsa patsogolo konkriti yobwezerezedwanso kudzera pamachitidwe akuthupi ndi mankhwala. Apa ndi kusanthula mwatsatanetsatane:

1. Katundu ndi ntchito zaGalasi

Fiberglass, inforganic yopanda zitsulo, imawonetsa izi:
Mphamvu yayikulu kwambiri: imalipira mphamvu zochepa za konkriti.
Kukana Kuchulukitsa: Chimani zisandutsidwe Mankhwala (mwachitsanzo, chloride azizindikiro, sulfis).
Kukhumudwa ndi kuwonongeka kukana **: milatho yamiyala kuti muchepetse kufalitsa ndikuchepetsa kuwonekera.

2. Zolakwika za Chuma

Kubwezeretsanso ophatikizidwa ndi malo otsalira a simenti pamalowo amatsogolera ku:
Zoyenera Kusinthana Kwambiri (ITZ): Kulumikizana bwino pakati pa recratid obwezerezedwanso ndi phala yatsopano ya simenti, ndikupanga njira zokwanira.
Umodzi wotsika: Othandizira (mwachitsanzo, cr⁻, son₄) kulowa mosavuta, kuwononga chitsulo kapena kuwonongeka kwa zitsulo.
Kulimbana Kwambiri ndi Thaw-Thaw Kukaniza: Kukula kwa Ice ku Pores kumapangitsa kuti kusokonezeke ndi kuwonongeka.

3. Njira za fiberglass pokonza kusintha

(1) Zotsatira zakuthupi
Zolepheretsa zoletsa: Kubalalika kofananiza microucracks a mlatho, kutseketsa kukula kwawo ndikuchepetsa njira zopangira makonzedwe okonza.
Kuchulukitsa: ulusi umadzaza ma pores, kutsika ndi kuchepetsedwa kusokonekera kwa zinthu zoyipa.

(2) Kukhazikika kwamankhwala
Alkali-Carber.
Kulimbikitsidwa: Mphamvu yolimba ya fiber-matrix yolumikizira imachepetsa chilema mu itz, kuchepetsa zoopsa za kukokoloka.

(3) Kukana mitundu inayake
Chloride ion kukana: Kuchepetsedwa kuchepetsedwa kumachepetsa, kuchedwetsa chitsulo.
Sulfate kuwukira kukana: Kupsinjika pang'ono kumachepetsa kuwonongeka kwa sulfate crystallization ndi kukulitsa.
Freeze-Thaw Kukhazikika Kwakukulu: Kusintha kosasinthika kumatenga nkhawa kuchokera ku mapangidwe ayezi, kuchepetsa malo.

4. Zochititsa chidwi

Mlingo wa fiber: Malo oyenera ndi 0,5% -2% (ndi voliyumu); Mitundu yowonjezera imapangitsa kusemphana ndikuchepetsa kusiyana.
Kutalika kwa Aber ndi Kubalalika: ulusi wautali (12-24 mm) Sinthani zolumikizira koma zimafunikira kugawa yunifolomu.
Khalidwe lobwezeretsedwanso: Madzi otumphukira kwambiri kapena otsalira matope amawononga ma fiber-matrix.

5. Kupeza Kafukufuku ndi Malingaliro Othandiza

Zotsatira Zabwino: Kafukufuku ambiri amawonetsa kuti kuli koyeneragalasiKuphatikiza komwe kumasintha kwambiri ungwiro, kukana kwa chloride, ndi kukana sulfate. Mwachitsanzo, 1% fiberglass imatha kuchepetsa chloride vaffion coeffication ndi 20% -30%.
Kugwira ntchito kwa nthawi yayitali: Kukhazikika kwa ulusi m'malo a alkaline kumafunikira chisamaliro. Zovala za alkalini-zosagwirizana kapena ulusi wosakanizidwa (mwachitsanzo, ndi polypropylene) imawonjezera kukhala ndi moyo.
Zoperewera: Zabwino kwambiri zobwezerezedwanso (mwachitsanzo, mawonekedwe apamwamba, zodetsa) zimatha kuchepetsa phindu la fibe.

6. Malangizo

Zochitika Zoyenera: Madera am'madzi, dothi lamchere, kapena magulu omwe amafunikira konkriti yayitali.
Sakanitsani kukhathamiritsa: Mlingo woyeserera, wobwezeretsanso wobwezeretsanso kwambiri, ndi ma syrnergies okhala ndi zowonjezera (mwachitsanzo, usica).
Kuwongolera kwapadera: onetsetsani kuti yunifolomu kufalikira kuti mupewe kuphwanya panthawi yosakanikirana.

Chidule

Fiberglass imathandizira kukana konkriti yobwezeretsanso konkriti yopukutira ndi kukhazikika kwa mankhwala. Ubwino wake umatengera mtundu wa fiber, mlingo, ndi kubwezeretsanso bwino. Kafukufuku wamtsogolo ayenera kuganizira za njira zazitali komanso zopangira zopanga mtengo kuti athandizire ntchito zazikuluzikulu.
