Iplastiki Eqinisiweyo yeFiberglass (FRP/GFRP)
* Iimveliso zefiberglass ezenziwe ngokwezifiso, ezipakishwe kwaye zithunyelwe ngokweemfuno zokwenza ngokwezifiso!
* I-FRP, ekwaziwa ngokuba yiFiber Reinforced Plastic (FRP), yinto edityanisiweyo eyenziwe ngemicu yeglasi kunye ne-resin. Ineempawu ezintle kakhulu zoomatshini kunye nokumelana nokugqwala, kwaye isetyenziswa kakhulu kwiinqanawa, kwiimoto, kulwakhiwo, kushishino lweekhemikhali, kumandla ombane nakwezinye iindawo.
* Iimveliso zeplastiki ze-FRP ezenziwe ngokwezifiso okanye izinto
I-FRP luhlobo lwezinto ezidityanisiweyo, ezenziwe ngefayibha yeglasi kunye neemveliso zayo ezifana nelaphu leglasi, iteyiphu, i-felt kunye ne-yarn njengezinto zokuqinisa kunye ne-resin yokwenziwa njengezinto ze-matrix. Ngenxa yamandla ayo ilingana nentsimbi, kwaye iqulethe izinto zeglasi, ikwanayo nombala, imilo, ukumelana nokugqwala, ubushushu bombane, ubushushu bobushushu kunye nezinye iimpawu zeglasi, ngoko ke ibizwa ngokomfuziselo ngokuba yi "glass fiber reinforced plastic".
I-FRP yaziwa ngomlinganiselo wayo ophezulu wamandla ukuya kubunzima, ukumelana nokugqwala, kunye nokuqina kwayo kwaye isetyenziswa kwiindlela ezahlukeneyo zokusebenza ezifana neshishini leemoto, i-aerospace, ulwakhiwo, kunye nelolwandle kunye nakwicandelo lezixhobo zokuhombisa.
Ziziphi iingenelo ezibonelelwa yi-FRP kunezinye iiplastiki?
Ukongeza iifayibha kwiifayibha zeglasi kunciphisa ubunzima kwaye kwandisa imodulus yokuguquguquka kunye namandla oomatshini. Ngenxa yoko, ezi zinto zingasetyenziselwa ukuvelisa izinto ezifuna uyilo oluchanekileyo, imida yokunyamezela kwangaphambili, ukudinwa okuphantsi, ukumelana nempembelelo ephezulu kunye neempawu ezilungileyo zokucinezelwa. Zingenza lula uyilo lwenxalenye kwaye ziphucule imveliso kunye nokusebenza kakuhle. Ii-FRP zikwanazo neempawu ezibalaseleyo zokuthintela ubushushu kunye ne-acoustic kwaye zinokumelana nohlaselo lweekhemikhali ezirhabaxa, impembelelo yamaza, iindawo ezifumileyo kunye nezivuthuvuthu/iziphepho.

Inkqubo yokuvelisa i-fiberglass
Ngokweempawu zezinto ze-FRP, iinkqubo eziphambili zokuvelisa ezisetyenziswa rhoqo ziquka ukubumba okujijekileyo, ukubumba ulungelelwaniso, ukubumba ucinezelo, kunye nokubumba ngesandla.
Zeziphi iimpawu ze-FRP?
* Okokuqala, ubunzima obulula kunye namandla aphezulu: uxinano lwe-FRP luphakathi kwe-1.5 ~ 2.0, yi-1/4 ~ 1 / 5 kuphela yentsimbi yekhabhoni, kodwa amandla okutsalwa asondele okanye adlule nalawo entsimbi yekhabhoni. Amandla athile okutsalwa kwe-epoxy FRP, amandla okudlala kunye nokucinezelwa anokufikelela ngaphezulu kwe-400Mpa.
* Okwesibini, iipropati zombane ezilungileyo: I-FRP yinto ebalaseleyo yokukhusela ubushushu, esetyenziselwa ukwenza ii-insulator, i-frequency ephezulu isenokukhusela iipropati ezilungileyo ze-dielectric.

Okwesithathu, ukusebenza kakuhle kobushushu: I-FRP ine-conductivity ephantsi yobushushu, yi-1/100 ~ 1/1000 kuphela yesinyithi, sisixhobo esihle kakhulu sokukhusela ubushushu.
Okwesine, uyilo oluhle: ngokwemfuneko yokuyila ngokuguquguquka iintlobo ngeentlobo zeemveliso zesakhiwo ukuhlangabezana neemfuno zokusetyenziswa kwemveliso zinokwenziwa zibe nomgangatho olungileyo. Unokukhetha ngokupheleleyo izinto ezifunekayo ukuze zihlangabezane nokusebenza kwemveliso.
Okwesihlanu, umsebenzi ogqwesileyo: ngokwemilo yemveliso, iimfuno zobugcisa, ukusetyenziswa kunye nenani leenkqubo zokubumba eziguquguqukayo. Inkqubo ilula, ingabunjwa ngaxeshanye, isiphumo sezoqoqosho sibalasele, ngakumbi kwimilo entsonkothileyo, akukho lula ukwenza inani elincinci leemveliso, ezibonakala ngakumbi kubukhulu bayo benkqubo.
