Mmetụta nke fiberglass na nguzogide mbuze nke ihe eji emegharịgharị (nke sitere na mkpokọta kọmpụta emegharịrị) bụ isiokwu nwere mmasị dị ukwuu na sayensị akụrụngwa na injinia obodo. Ọ bụ ezie na kọmpụta arụgharịrị arụgharị na-enye uru gburugburu ebe obibi na ijikwa akụrụngwa, ihe eji arụ ọrụ ya na ịdịte aka ya (dịka ọmụmaatụ, mgbochi mbuze) na-adịkarị ala karịa kọmpat. Fiberglass, dị ka aihe na-agba ume, nwere ike welie arụmọrụ nke kọmpụta emegharịrị site na usoro anụ ahụ na kemịkal. Nke a bụ nyocha zuru ezu:
1. Ngwongwo na Ọrụ nkeFiberglass
Fiberglass, ihe inorganic na-abụghị ọla, na-egosipụta njirimara ndị a:
Ike ike dị elu: Na-akwụ ụgwọ maka ikike nkwụsịtụ dị ala nke ihe.
Nguzogide corrosion: Na-eguzogide ọgụ kemịkalụ (dịka ọmụmaatụ, ion chloride, sulfates).
Nkwụsi ike na mgbawa mgbawa ***: Akwado microcracks iji gbuo oge ịgbawa ma belata ikike.
2. Mkpirisi adịghị ike nke ihe eji emegharịgharị
Mkpokọta simenti residual mfọdu n'elu ha na-eduga na:
Mpaghara mgbanwe ihu ihu na-adịghị ike (ITZ): Njikọ na-adịghị mma n'etiti mkpọ a na-emegharịgharị na tapatị ciment ọhụrụ, na-emepụta ụzọ ndị nwere ike ịgbasa.
Enweghi ike dị ala: ihe na-ekpo ọkụ (dịka, Cl⁻, SO₄²⁻) na-abanye n'ime ngwa ngwa, na-eme ka nchara nchara ma ọ bụ mmebi gbasaa.
Nguzogide na-ajụ oyi na-adịghị mma: Mgbasa ice na pores na-ebute mgbawa na spalling.
3. Usoro nke Fiberglass na-emeziwanye nguzogide nbibi
(1) Mmetụta mgbochi anụ ahụ
Mgbochi mgbawa: fibers gbasasịrị n'otu n'otu na-akwakọba microcracks, na-egbochi uto ha na ibelata ụzọ maka ihe ndị na-emebi emebi.
Mgbakọ emelitere: Fibers na-ejupụta pores, na-ebelata porosity ma na-ebelata mgbasa nke ihe ndị na-emerụ ahụ.
(2) Chemical kwụsie ike
fiberglass na-eguzogide alkalin(dịka ọmụmaatụ, AR-glass): eriri ndị a na-emeso ihu na-anọgide na-eguzosi ike na gburugburu alkali dị elu, na-ezere mmebi.
Nkwado ihu: Njikọ fiber-matrix siri ike na-ebelata ntụpọ dị na ITZ, na-ebelata ihe egwu mbuze mpaghara.
(3) Nguzogide n'ụdị nbibi dị iche iche
Nguzogide ion chloride: mbelata nguzobe mgbape na-ebelata ntinye ntinye, na-egbu oge corrosion ígwè.
Nguzogide ọgụ sulfate: Mbelata mgbape na-ebelata mmebi sitere na kristal sulfate na mgbasawanye.
Ọdịte n'ime friza-thaw: Mgbanwe nke eriri na-etinye nrụgide sitere na nguzobe ice, na-ebelata oke elu.
4. Isi Ihe Na-emetụta
Usoro onunu ogwu: Oke kacha mma bụ 0.5%-2% (site na olu); ngafe eri na-akpata ụyọkọ na mbelata compactness.
Ogologo eriri na mgbasa: eriri ogologo (12-24 mm) na-eme ka ike sie ike mana ọ chọrọ nkesa otu.
Ọdịmma nke mkpokọta emegharịrị: Mmụba mmiri dị elu ma ọ bụ ọdịnaya ngwa ngwa fọdụrụ na-ebelata njikọ nke fiber-matrix.
5. Nchọpụta nyocha na njedebe bara uru
Mmetụta dị mma: Ọtụtụ nnyocha na-egosi na kwesịrị ekwesịfiberglassmgbakwunye na-abawanye nke ọma enweghị ike, nguzogide chloride na nguzogide sulfate. Dịka ọmụmaatụ, 1% fiberglass nwere ike belata ọnụọgụ mgbasa ozi chloride site na 20%-30%.
Ịrụ ọrụ ogologo oge: Ịdị ogologo nke eriri na gburugburu alkaline chọrọ nlebara anya. Ihe mkpuchi na-eguzogide alkalin ma ọ bụ eriri ngwakọ (dịka ọmụmaatụ, nwere polypropylene) na-eme ka ndụ dịkwuo ogologo.
Oke: Mkpokọta ejigharịgharị arụgharị adịghị mma (dịka ọmụmaatụ, elu porosity, adịghị ọcha) nwere ike ibelata uru eriri.
6. Ngwa Aro
Ọnọdụ dabara adaba: Gburugburu mmiri, ala saline, ma ọ bụ ihe arụrụ arụ na-achọ kọmpụta na-adịte ogologo oge.
Ngwakọta ngwakọta: Nwalee usoro onunu ogwu, nchikota nchikota nchikota meghariri, yana mmekorita ya na ihe mgbakwunye (dịka ọmụmaatụ, uzuzu silica).
Njikwa ogo: Gbaa mbọ hụ na mgbasa nke eriri otu dị ka ịzenara nhịkọ mgbe ị na-agwakọta.
Nchịkọta
Fiberglass na-akwalite nguzogide mbuze nke ihe eji emegharịgharị ihe site na nkwụsi ike anụ ahụ yana nkwụsi ike kemịkalụ. Ịdị irè ya na-adabere n'ụdị eriri, usoro onunu ogwu, na ogo mkpokọta emegharịrị. Nnyocha n'ọdịnihu kwesịrị ilekwasị anya na ogologo oge na-adịte aka na ụzọ mmepụta ihe dị irè iji mee ka ngwa injinia buru ibu dị mfe.
