Kukanganiswa kweFiberglass paKuramba Kukukurwa kweKonkreti Yakadzokororwa

Kukanganiswa kwe fiberglass pakuramba kudonha kwekongiri yakadzokororwa (yakagadzirwa nemidziyo yekongiri yakadzokororwa) inyaya inonyanya kufarirwa musainzi yezvinhu uye mainjiniya ekuvaka. Kunyange zvazvo kongiri yakadzokororwa ichipa mabhenefiti ezvakatipoteredza uye ekudzokororwa kwezviwanikwa, hunhu hwayo hwemakanika uye kugara kwenguva refu (semuenzaniso, kuramba kudonha kwekongiri) kazhinji hazvina kunaka pane kongiri yemazuva ano. Fiberglass, senzira yekuwedzera simba rekugadzira.zvinhu zvinosimbisa, inogona kuwedzera mashandiro ekongiri yakadzokororwa kuburikidza nemaitiro emuviri uye emakemikari. Heino ongororo yakadzama:

1. Hunhu uye Mabasa eGirazi reFiberglass

Fiberglass, chinhu chisina kugadzirwa nesimbi, ine hunhu hunotevera:
Simba guru rekudhonza: Rinotsiva simba shoma rekudhonza rekongiri.
Kuramba ngura: Kuramba kurwiswa nemakemikari (semuenzaniso, ma chloride ions, sulfates).
Kusimba uye kuramba kutsemuka**: Kunobatanidza kutsemuka kudiki kuti kunonotse kupararira kwetsemuka uye kuderedza kupinda kwemvura.

2. Kusagadzikana kweKonkriti Yakadzokororwa

Zvinhu zvakagadziriswazve zvine simende inosara ine maburi pamusoro pazvo zvinotungamirira ku:
Nzvimbo isina kusimba yekuchinja nzvimbo (ITZ): Kusabatana zvakanaka pakati pezvinhu zvakagadziriswazve nesimbi itsva yesimbi, zvichiita kuti pave nenzira dzinopinda mvura.
Kusapinda mvura zvakanyanya: Zvinhu zvinokukurwa (semuenzaniso, Cl⁻, SO₄²⁻) zvinopinda zviri nyore, zvichikonzera ngura yesimbi kana kukuvara kukuru.
Kusakwanisa kunyunguduka nechando: Kuwedzera kwechando mumaburi kunokonzera kutsemuka nekubuda kwemvura.

3. Nzira dzeFiberglass mukuvandudza Kuramba Kukura Kwevhu

(1) Mhedzisiro Yezvipingamupinyi Zvemuviri
Kudzivirira kutsemuka: Matayi akapararira zvakaenzana anodzivirira kutsemuka kudiki, achivhara kukura kwawo uye achideredza nzira dzezvinhu zvinokukurwa.
Kusimba kwakawedzerwa: Fibers dzinozadza maburi, dzichideredza maburi uye dzinoderedza kupararira kwezvinhu zvinokuvadza.

(2) Kugadzikana kweMakemikoro
Firiji yefiberglass isingapindi alkali(semuenzaniso, AR-girazi): Fiber dzakagadziriswa pamusoro dzinoramba dzakagadzikana munzvimbo dzine alkali yakawanda, dzichidzivirira kuora.
Kusimbiswa kweinterface: Kubatana kwakasimba kwefiber-matrix kunoderedza zvikanganiso muITZ, zvichideredza njodzi dzekukukurwa kwevhu munzvimbo.

(3) Kuramba Kukura Kwemhando Dzekukurwa Kwevhu
Kuramba ma ion e chloride: Kudzikira kwekuumbwa kwemutswe kunononotsa kupinda kweCl⁻mutsvo, zvichinonotsa ngura yesimbi.
Kusabatwa nesulfate: Kukura kwetsanga kwakadziviswa kunoderedza kukuvara kunokonzerwa nekugadzirwa kwesulfate crystallization uye kukura kwayo.
Kugara kwenguva refu kwechando: Kuchinjika kwefiber kunoderedza kushushikana kubva pakuumbwa kwechando, zvichideredza kupararira kwemvura pamusoro.

4. Zvinhu Zvikuru Zvinopesvedzera

Chiyero chefiber: Chiyero chakanaka ndeche 0.5%–2% (nehuwandu); fiber dzakawandisa dzinokonzera kuungana uye kudzikira kwekuoma.
Kureba kwefiber uye kupararira kwayo: Fiber dzakareba (12–24 mm) dzinovandudza kusimba asi dzinoda kupararira kwakafanana.
Hunhu hwezvinhu zvakagadziriswazve: Kunyudzwa kwemvura yakawanda kana kuti huwandu hwemortar hunoderedza kubatana kwefiber-matrix.

5. Zvakawanikwa muKutsvagurudza uye Mhedziso Dzinoshanda

Migumisiro Yakanaka: Ongororo dzakawanda dzinoratidza kuti zvakakodzerafiberglassKuwedzera kwacho kunovandudza zvakanyanya kusapinda kwemvura, kuramba kwechloride, uye kuramba kwesulfate. Semuenzaniso, 1% fiberglass inogona kuderedza chloride diffusion coefficients ne20%–30%.
Kushanda kwenguva refu: Kugara kwenguva refu kwemafiber munzvimbo dzine alkaline kunoda kutarisirwa. Macoatings anodzivirira alkali kana mahybrid fibers (semuenzaniso, ane polypropylene) anowedzera hupenyu hurefu.
Zvipingamupinyi: Zvinhu zvisina kunaka zvakadzokororwa (semuenzaniso, kuzara kwakanyanya, tsvina) zvinogona kuderedza mabhenefiti efaibha.

6. Mazano Ekushandisa

Mamiriro ezvinhu akakodzera: Nzvimbo dzemugungwa, ivhu rine munyu, kana zvivakwa zvinoda kongiri yakadzokororwa inogara kwenguva refu.
Kugadzirisa musanganiswa: Edza chiyero chefiber, chiyero chekutsiva aggregate chakadzokororwa, uye kushanda pamwe chete nezvimwe zvinowedzera (semuenzaniso, silica fume).
Kudzora kunaka: Iva nechokwadi chekuti fiber inopararira zvakaenzana kudzivirira kuungana panguva yekusanganisa.

Pfupiso

Fiberglass inowedzera kuramba kwekongiri yakadzokororwa kuburikidza nekusimbisa muviri uye kugadzikana kwemakemikari. Kushanda kwayo kunoenderana nerudzi rwefiber, chiyero, uye mhando ye fiber yakadzokororwa. Tsvagiridzo yeramangwana inofanira kutarisa pakugara kwenguva refu uye nzira dzekugadzira dzinoshanda zvishoma kuti zvibatsire mainjiniya makuru.
