Yiziphi amapulasitiki aqiniswe nge-fiberglass?
Ipulasitiki eqinisiwe ye-Fiberglassiyinhlanganisela yezinto ezinezinhlobonhlobo eziningi, izakhiwo ezihlukene, kanye nezinhlobonhlobo zokusetshenziswa. Kuyinto entsha esebenzayo eyenziwe nge-synthetic resin ne-fiberglass ngenqubo eyinhlanganisela.

Izici zepulasitiki eqinisiwe ye-fiberglass:
(1) ukumelana nokugqwala okuhle: I-FRPkuyizinto ezinhle ezimelana nokugqwala, zomkhathi; amanzi kanye nokuhlushwa okujwayelekile kwama-acids nama-alkali; usawoti kanye nezinhlobonhlobo zamafutha kanye nezincibilikisi zinokuphikiswa okuhle, sekusetshenziswe kabanzi kuzo zonke izici zokubola kwamakhemikhali. Ingabe esikhundleni se-carbon steel; insimbi engagqwali; ukhuni; izinsimbi ezingenayo insimbi nezinye izinto.
(2) Isisindo esincane namandla aphezulu:Ukuminyana kwesihlobo se-FRP kuphakathi kuka-1.5 ~ 2.0, kuphela i-1/4~1/5 yensimbi ye-carbon, kodwa amandla aqinile aseduze noma adlule ngisho nalawo ensimbi ye-carbon, futhi amandla angafaniswa nalawo ensimbi ye-alloy yezinga eliphezulu, esetshenziswa kabanzi endaweni ye-aerospace; iziqukathi ezinengcindezi ephezulu kanye neminye imikhiqizo edinga ukwehlisa isisindo sakho.
(3) izici zikagesi ezinhle:I-FRP iyinto enhle kakhulu yokuvikela ukukhiqizwa kwama-insulators, imvamisa ephezulu isengakwazi ukugcina okuhle.
(4) izici ezinhle zokushisa:I-FRPconductivity ongaphakeme, izinga lokushisa ekamelweni 1.25 ~ 1.67KJ kuphela metal 1/100 ~ 1/1000 kuyinto enhle kakhulu ukufakwa ezishisayo impahla. Endabeni yokushisa okuphezulu ngokushesha, ukuvikela okushisayo okufanelekile nezinto ezimelana nokugqwala.
(5) ukusebenza kahle kwenqubo:ngokusho kokuma komkhiqizo ukukhetha inqubo yokubumba futhi inqubo elula ingaba ukubumba.
(6) Ukuklama okuhle:impahla ingakhethwa ngokugcwele ngokuvumelana nezidingo zokuhlangabezana nezidingo zokusebenza komkhiqizo kanye nesakhiwo.
(7) imoduli ephansi yokunwebeka:i-modulus ye-elasticity ye-FRP inkulu izikhathi ezingu-2 kunezokhuni, kodwa izikhathi ezingu-10 ezincane kunezinsimbi, ngakho-ke kuvame ukuzwakala ukuthi ukuqina akwanele esakhiweni somkhiqizo, futhi kulula ukukhubazeka. Isixazululo, singenziwa sibe isakhiwo segobolondo elincanyana; isakhiwo sesemishi singenziwa futhi nge-high modulus fiber noma ifomu lokuqinisa ubambo.
(8) Ukumelana nezinga lokushisa okungalungile kwesikhathi eside:jikeleleI-FRPayikwazi ukusetshenziswa isikhathi eside emazingeni okushisa aphezulu, i-polyester resin yenhloso ejwayelekile ye-FRP ku-50 degrees ngaphezu kwamandla izoncishiswa kakhulu.
(9) Isenzakalo sokuguga:ukukhanya kwe-ultraviolet; umoya, isihlabathi, imvula neqhwa; imidiya yamakhemikhali; ukucindezeleka komshini neminye imiphumela kuholela kalula ekonakaleni kokusebenza.
(10) Amandla okugunda okuphakathi okuphansi:Amandla e-interlayer shear athwalwa yi-resin, ngakho-ke aphansi. Kungenzeka ukuthuthukisa amandla okubopha kwe-interlayer ngokukhetha inqubo, usebenzisa i-ejenti yokuhlanganisa nezinye izindlela, nokugwema ukugunda kwe-interlayer ngangokunokwenzeka lapho uklama umkhiqizo.
