Ziziphi iiplastiki ezomelezwe ngefiberglass?
Iplastiki eyomeleziweyo yeFiberglassyimathiriyeli edibeneyo eneentlobo ezininzi, iipropati ezahlukeneyo, kunye noluhlu olubanzi lokusetyenziswa. Yinto entsha esebenzayo eyenziwe nge-synthetic resin kunye ne-fiberglass ngenkqubo edibeneyo.

Iimpawu zeplastiki eyomeleziweyo yefiberglass:
(1) ukunganyangeki kakuhle komhlwa: FRPyimathiriyeli elungileyo enganyangekiyo kwi-atmosphere; amanzi kunye noxinzelelo oluqhelekileyo lwe-acids kunye ne-alkali; ityuwa kunye neentlobo ezahlukeneyo zeoli kunye ne-solvents zinokuchasana okulungileyo, zisetyenziswe ngokubanzi kuzo zonke iinkalo zokubola kweekhemikhali. Ngaba ukubuyisela intsimbi yekhabhoni; yenziwe ngentsimbi eshayinayo; iinkuni; iintsimbi ezingenayo i-ferrous kunye nezinye izinto.
(2) Ubunzima obulula kunye namandla aphezulu:Ubuninzi be-FRP buphakathi kwe-1.5 ~ 2.0, kuphela i-1/4 ~ 1/5 yensimbi ye-carbon, kodwa amandla okuqina asondele okanye adlule kwi-carbon steel, kwaye amandla anokuthelekiswa nalawo ensimbi ye-alloy high-grade, esetyenziswa ngokubanzi kwi-aerospace; izitya ezinoxinzelelo oluphezulu kunye nezinye iimveliso ezifuna ukunciphisa ubunzima bomzimba.
(3) iimpawu zombane ezilungileyo:I-FRP yinto egqwesileyo yokugquma i-insulators ekwenzeni i-insulators, i-high-frequency isenokuthi igcine ilungile.
(4) iimpawu ezintle zobushushu:FRPconductivity ephantsi, ubushushu begumbi 1.25 ~ 1.67KJ kuphela isinyithi 1/100 ~ 1/1000 yinto ebalaseleyo yokufakelwa kwe-thermal. Kwimeko yokushisa okuphezulu ngokukhawuleza, yinto efanelekileyo yokukhusela i-thermal kunye nezixhobo ezichasene ne-corrosion.
(5) inkqubo egqwesileyo yokusebenza:ngokwemilo yemveliso ukukhetha inkqubo yokubumba kunye nenkqubo elula ingaba ngumbumba.
(6) Ukuyila kakuhle:izinto eziphathekayo zinokukhethwa ngokupheleleyo ngokweemfuno zokuhlangabezana neemfuno zokusebenza kwemveliso kunye nesakhiwo.
(7) imodyuli esezantsi yokunwebeka:i-modulus ye-elasticity ye-FRP iphindwe ngama-2 amakhulu kunomthi, kodwa amaxesha angama-10 amancinci kuneyentsimbi, ngoko ke kudla ngokuvakala ukuba ukuqina akwanelanga kwisakhiwo semveliso, kwaye kulula ukukhubazeka. Isisombululo, sinokwenziwa kwisakhiwo seqokobhe elincinci; Ulwakhiwo lwesangweji lunokwenziwa kwakhona ngefayibha yemodulus ephezulu okanye ukuqinisa iimbambo.
(8) Ukumelana nobushushu bexesha elide:jikeleleFRPayinakusetyenziswa ixesha elide kumaqondo aphezulu, i-polyester ye-resin ye-resin ye-FRP kwi-50 degrees ngaphezu kwamandla iya kuncitshiswa kakhulu.
(9) Ukwaluphala:ukukhanya kwe-ultraviolet; umoya, isanti, imvula nekhephu; imidiya yeekhemikhali; uxinzelelo koomatshini kunye nezinye iziphumo ngokulula zikhokelela ekuthotyweni kwentsebenzo.
(10) Amandla asezantsi okucheba okuphakathi:Amandla e-shear interlayer athwalwa yi-resin, ngoko ke aphantsi. Kunokwenzeka ukuphucula amandla okudibanisa i-interlayer ngokukhetha inkqubo, usebenzisa i-agent yokudibanisa kunye nezinye iindlela, kunye nokuphepha i-interlayer shear kangangoko kunokwenzeka xa uyila imveliso.
