Tasirin fiberglass a kan lalacewa ta recycled polrete (wanda aka yi da tara tattara kwastomomi) babban batun mahimmancin kimiyya da injiniya na zamani. Yayin da aka sake amfani da kayan kwalliya yana ba da fa'idodi na kayan aikin da ke tattare da kayan aikin ci gaba, na kayan aikinta da tsoratarwa (misali, lalacewa) galibi ne ga kankare na al'ada. Fiberglass, a matsayinsake sarrafa kayan, na iya haɓaka aikin da aka sake amfani da shi ta hanyoyin motsa jiki da na sunadarai. Ga cikakken bayani:
1. Properties da ayyuka naFiberglass
Fiberglass, kayan rashin ƙarfe ba na ƙarfe ba, suna nuna halaye masu zuwa:
Strowerarfin mai tsayi da yawa: rama don ƙarancin ƙarfin ƙarfin gwiwa.
Corroon juriya: ya sake tsayayya da sunadarai (misali, oons na chloride, sulfate).
Toughening da crack juriya **: gado microcacks don jinkirta yaduwar crack da rage ƙarfi.

An sake haɗa tarin abubuwa masu ciminti mai narkewa a saman su na kaiwa ga:
Yankin canjin canzawa (ITZ): Bontari mara kyau tsakanin tara kayan mikiya da sabon ciminti, ƙirƙirar hanyoyin da za a iya lalacewa.
Lowari mara iyaka: Maɓallin Kasa (misali, cl⁻, So₄²⁻) a sauƙaƙe, yana haifar da lalata ƙarfe ko lalacewa mai lalacewa.
Talauci Dreze-Thaw juriya: fadada kankara a cikin pores ya sanya fashewa da zubewa.
3. Masu amfani da fiberglass a cikin inganta juriya na lalacewa
(1) tasirin jiki
Cack Cackhiition: Tashar da Fibers Hibers Gridge uscracks, tare da bunkasa haɓakarsu da rage hanyoyin don wakilan ɓarna.
Ingantaccen daidaitawa: 'Yan bindiga sun cika pores, baranda na rage moro da kuma kawar da yaduwar abubuwa masu cutarwa.
(2) Dankali
Alkali-resistanterberglass Fiberglass(misali gilashi): Fibers da aka yi da farfajiya ya zama barga a cikin mahalli mai girma-alkali, guje wa lalata.
Interface ta inganta: Fiber-matrix tare da rage lahani a cikin IDZ, yana rage haɗarin lalacewa.
(3) juriya ga takamaiman nau'in lalacewa
Chloride ion jure juriya: Rage samuwar fasa fasahar sworms, jinkirtawa da bakin karfe.
Karshen harin sulfate: tsaftace saurin rage lalata daga sulfate crystallization da fadada.
Dogeze-Thaw dillability: Fiber sassauza yana shan wahala daga Ice samuwar, ragewar shimfidar wuri.
4. Memy m tasiri abubuwa
Kewayon fiber slatage: iyaka mafi kyau shine 0.5% -2% (ta girma); Yawan ribers yana sa hadari da rage hadari.
Fiber tsayinsa da watsawa: Fibpers (12-24 mm) Inganta wahala amma yana buƙatar rarraba uniform.
Ingancin da aka sake amfani da shi: Ingurewa mai ruwa ko resan iska mai gudana fiber-matrix.
5. Binciken bincike da na ƙarshe
Ingantaccen sakamako: Mafi yawan karatu ya nuna cewa ya dacefiberglassBugu da kari muhimmanci inganta halin sani, chloride resistance, da juriya na sulfate. Misali, 1% fiberglass na iya rage coodsions na 20% -30%.
Dogon aiki na dogon lokaci: karkara na zaruruwa a cikin alkaline mahalli na bukatar kulawa. Alkali-resistant cheatings ko hybrid fibers (misali, tare da polypropylene) haɓaka tsawon rai.
Iyakantarwa: Talauci mai ƙima mai inganci (misali, babban mamaki, impurities) na iya rage amfanin fa'idodin fiber.
6. Shawarwari
Yanayin da ya dace: Yanayin Marine, Kasa mai saline, ko tsarin da ke buƙatar babban ƙimar da aka sake fasalin kankare.
Haɓakawa: Gwajin Fir Sifen, tattara tara rabo maye gurbin, da syngies tare da ƙari (misali, silica fue).
Gudanar da Inganci: Tabbatar da watsawa fiber na fiber don gujewa clumping yayin hadawa.
Taƙaitawa
Fiberglass yana haɓaka juriya na lalacewa ta polrete ta hanyar toughening na zahiri da kuma haɓaka sunadarai. Ingancin sa ya dogara da nau'in zare, sashi, da kuma sake rarraba ingancin. Bincike mai zuwa zai kamata ya mai da hankali kan tsawan lokaci da kuma hanyoyin samar da tsada mai inganci don sauƙaƙe aikace-aikacen injiniyoyi.
