Yintoni iplastiki yefayibha eyomeleziweyo?
Iiplastiki eziqiniswe kwifayibha yeglasi zizinto ezininzi ezahlukeneyo ezihlanganisiweyo ezineempawu ezahlukeneyo kunye nokusetyenziswa okubanzi.Yinto entsha esebenzayo eyenziwe nge-synthetic resin kunyeimathiriyeli edibeneyo yefiberglass ngenkqubo edibeneyo.
Iimpawu zeplastiki zefayibha ezomeleziweyo:
(1Ukuchasana nokugqwala okuhle: I-FRP yinto elungileyo ekwaziyo ukumelana nomhlwa.Inokumelana kakuhle nomoya;amanzi kunye noxinzelelo oluqhelekileyo lwe-asidi kunye ne-alkali;ityuwa, ii-oyile ezahlukeneyo kunye nezinyibilikisi, kwaye isetyenziswe ngokubanzi kwimichiza yokuchasana nokubola.kuzo zonke iinkalo.Ithatha indawo yentsimbi yekhabhoni;yenziwe ngentsimbi eshayinayo;iinkuni;iintsimbi ezingenayo i-ferrous kunye nezinye izinto.
(2) Ubunzima bokukhanya kunye namandla aphezulu: Ubuninzi be-FRP buphakathi kwe-1.5 kunye ne-2.0, eyi-1/4 kuphela kwi-1/5 ye-carbon steel, kodwa amandla okuqina asondele okanye angaphezulu kunekhabhoni. intsimbi, kunye nokomelela kunokuthelekiswa nentsimbi yodidi oluphezulu., zisetyenziswa ngokubanzi kwi-aerospace;izitya ezinoxinzelelo oluphezulu kunye nezinye iimveliso ezifuna ukunciphisa ubunzima bazo.
(3) Iimpawu zombane ezilungileyo: I-FRP yinto egqwesileyo yokugquma, esetyenziselwa ukwenza i-insulators, kwaye isenokugcina ukusebenza kakuhle kwi-frequencies ephezulu.
(4) Ukusebenza kakuhle kwe-thermal: I-FRP ine-conductivity yombane ephantsi, i-1.25 ~ 1.67KJ kwiqondo lokushisa, kuphela i-1/100 ~ 1/1000 yentsimbi yinto egqwesileyo yokufakelwa kwe-thermal.Ilungele ukukhuselwa kwe-thermal kunye nokuxhatshazwa kwe-ablation phantsi kweemeko zokushisa eziphezulu zesikhashana.
(5) Ukusebenza kwenkqubo egqwesileyo: inkqubo yokubumba inokukhethwa ngokwemilo yemveliso, kwaye inkqubo ilula kwaye inokubunjwa ngexesha elinye.
(6) Ukuqulunqwa okulungileyo: izinto eziphathekayo zinokukhethwa ngokupheleleyo ngokweemfuno ukuhlangabezana neemfuno zokusebenza kwemveliso kunye nesakhiwo.
(7) I-modulus e-elastic ephantsi: I-modulus elastic ye-FRP iphindwe ngama-2 amakhulu kunomthi kodwa amaxesha angama-10 amancinci kuneyentsimbi, ngoko ke kudla ngokuvakalelwa kukuba ukuqina akwanelanga kwisakhiwo semveliso kwaye kulula ukukhubazeka.Isisombululo sinokwenziwa kwisakhiwo seqokobhe elincinci;isakhiwo sesandwich sisenokwenziwa ngendlela yeentsinga eziphezulu zemodulus okanye ukuqinisa iimbambo.
(8) Ukuchasana nokushisa kwexesha elide: Ngokuqhelekileyo, i-FRP ayikwazi ukusetyenziswa ixesha elide kwiqondo lokushisa eliphezulu, kwaye amandla e-FRP ye-resin ye-polyester yenjongo jikelele iya kuncipha kakhulu xa ingaphezulu kwe-50 degrees.
(9) Isiganeko sokuguga: phantsi kwesenzo semisebe ye-ultraviolet;umoya, isanti, imvula nekhephu;imidiya yeekhemikhali;uxinzelelo lomatshini, njl., kulula ukubangela ukuthotywa kokusebenza.
(10) Amandla e-interlaminar okucheba asezantsi: Amandla okucheba kwe-interlaminar athwalwa yi-resin, ngoko aphantsi.I-adhesion ye-interlayer inokuphuculwa ngokukhetha inkqubo, usebenzisa i-arhente yokudibanisa, njl., kwaye uzame ukuphepha ukucheba kwe-interlayer ngexesha loyilo lwemveliso.
Izinto eziluncedo kwiglasi yefiber yeplastiki eyomeleziweyo:
Iqondo lobushushu elikwaziyo ukumelana nobushushu leplastiki yefayibha eyomeleziweyo liphezulu kakhulu kunolo lingenaglasi, ngakumbi iiplastiki zenayiloni.
Iiplastiki ezomeleziweyo zefayibha yeglasi zinokushwabana okuphantsi kunye nokuqina okuphezulu.
Ifayibha yeglasi eyomeleziweyo yeplastiki ayigxininisi ukuqhekeka, kunye nokumelana nempembelelo yefemoglas fibra de vidrio iplastiki iphuculwe kakhulu
Amandla eplastiki ezomeleziweyo zefayibha yeglasi aphezulu, anje: amandla okuqina, amandla acinezelayo, amandla okugoba, zonke ziphezulu kakhulu.
Ngenxa yokongezwa kwezinye izongezo,i-fiber gllasiiplastiki ezomeleziweyo ziye zanciphisa kakhulu ukusebenza kokutsha kweglasi yefiber eyomeleziweyo yeeplastiki, kwaye uninzi lwemathiriyeli alukwazi ukuvutha, ngoko yinto ebuyisela ilangatye.
Ukungalungi kweeplastiki zefayibha zeglasi ezomeleleyo:
Ngenxa yokongezwa kwekunye ne-glassfiber, i-glass fibre eyomeleziweyo yeplastiki iye yaba opaque, kwaye ibonakala phambi kokuba yongeze i-glass fiber.
I-fiber yeglasi yeplastiki eyomeleziweyo yeplastiki inokuqina okuphantsi kunye nokunyuka kwe-brittleness kuneplastiki ngaphandle kwefayibha yeglasi;
Ngenxa yokongezwa kwefayibha yeglasi, i-viscosity enyibilikayo yazo zonke izinto iyanda, ubumanzi buba buthathaka, kwaye uxinzelelo lwenaliti luphezulu kakhulu kunolo ngaphandle kwefiber yeglasi.Ukubumba inaliti eqhelekileyo, ubushushu benaliti yazo zonke iiplastiki ezomeleziweyo buphezulu kunoko ngaphandle kokongeza ifayibha yeglasi.Ifiber yeglasi ngaphambili yaphakanyiswa yi-10℃-30℃.
Ngenxa yokongezwa kwefiber yeglasi kunye nezongezo, iipropati ze-hygroscopicdaw fiberglass iiplastiki ezomeleziweyo zongezwa kakhulu.Iiplastiki ezinyulu zantlandlolo ezingafunxi amanzi nazo ziyakufunxa.Ngoko ke, kufuneka zomiswe ngexesha lokubumba inaliti.
Ngexesha lenkqubo yokubumba yeglasi yefiber eyomeleziweyo, ifayibha yeglasi inokungena kumphezulu wemveliso yeplastiki, yenze umphezulu wemveliso ube rhabaxa kakhulu kwaye unamachokoza.Ukuze ufezekise umgangatho ophezulu womgangatho, umatshini wokushisa wokubumba usetyenziselwa ukutshisa isikhunta ngexesha lokubumba, ukuze i-polymer yeplastiki ingene kumphezulu wemveliso, kodwa umgangatho wokubonakala kweplastiki ecocekileyo ayinakufezekiswa.
Emva kokuba i-fiber yeglasi iqinisiwe,e glass fiberglass sisixhobo esinobunzima obuphezulu.Emva kokuba isongezelelo siguquguquke kubushushu obuphezulu, yirhasi eyonakalisa kakhulu, ebangela ukunxiba okukhulu kunye nokugqwala kwi-screw kunye nenaliti yokubumba umatshini wokubumba inaliti.Ngoko ke, olu hlobo lwempahla lusetyenziswa kwimveliso.Xa usebenzisa iimolds kunye noomatshini bokubumba inaliti, nikela ingqalelo kunyango oluchasene ne-corrosion kunye nonyango lobulukhuni bomphezulu besixhobo.
Ukuqiniswa kwempembelelo yefiber yeglasi kwinayiloni
Inayiloni, ekwabizwa ngokuba yi-polyamide, yimathiriyeli yokwenziwa kunye noluhlu olubanzi lwezicelo, ezisetyenziswa kwilaphu, ukupakisha, iinxalenye zoomatshini kunye nezinye iindawo.
Njengeplastiki yobunjineli, i-PA66 iqulethe inani elikhulu lamaqela e-hydrophilic amide, ekhawulela intsimi yesicelo sayo.Isetyenziswa ngokuqhelekileyo kwishishini ukuyiguqula ngokusebenzisa i-copolymerization, ukudibanisa ukuqina, kunye nokomeleza.
I-Glass fiber reinforcement yindlela esetyenziswa ngokuqhelekileyo yokuguqulwa.Inokuphucula ngokufanelekileyo ukuxhathisa ukunxiba, amandla, ubulukhuni kunye nokuzinza komda wenayiloni.
I-glass fiber yenziwe nge-pyrophyllite, isanti ye-quartz, i-limestone kunye nezinye iiminerali ngokudubula kobushushu obuphezulu, umzobo wocingo, ukujija, ukuthunga kunye nezinye iinkqubo, kunye nobubanzi bayo be-monofilament malunga nee-microns ezimbalwa.
Umgaqo wokuqiniswa kwefayibha yeglasi: Kukho iindlela ezintathu zefayibha yokufunxa amandla empembelelo: ukuphuka kwefayibha, ukutsalwa kwefayibha, kunye nokuqhekeka kweresin.Xa ubude befayibha bunyuka, ukutsalwa kwefayibha ngaphandle kudla amandla amaninzi, okuluncedo ekuphuculeni amandla empembelelo.
I-PA66 / iglasi ye-fiber composite imathiriyeli inokufunxa amanzi aphantsi, amandla athile aphezulu kunye nokumelana neekhemikhali, kwaye iimveliso zayo zinokumelana nokufunxeka okuhle kokufuma, ukuzinza komda, amandla aphezulu, ukuqina, kunye nokusebenza komgangatho, ngoko ke isetyenziswa kakhulu koololiwe, oomatshini, iimoto. , izixhobo zombane kunye nezinye iinkalo.
Ubude beimathiriyeli elastiki imodulus ifayibha yeglasiesetyenziswa ngokubanzi ukuqinisa inayiloni imalunga ne-3mm ukuya kwi-12mm.Njengoko ubude befiber bukhula, umphumo wokomelezwa kwezinto uyakhula.Ilungile malunga ne-12mm.
Ngokuqhelekileyo, ubude bei-fiberglass filamentyi 12mm, kunye nobude bei-fiber yeglasi eqoshiweuya 3mm.Xa kuthelekiswa nefayibha yeglasi emfutshane, into ephawulekayo yokuqiniswa kwefiber yeglasi ende kukuba amandla empembelelo aphindwe kabini.Ukongeza, imidibaniso yenayiloni eyomeleziweyo yeglasi ende ineengenelo zamandla aphezulu, ubungqongqo obuphezulu, amandla efuthe elibukhali, ukumelana nobushushu bexesha elifutshane kunye nokumelana nokudinwa okuhle, kwaye isenokugcina iipropathi ezilungileyo zoomatshini kwindawo yobushushu obuphezulu kunye nokufuma okuphezulu., enokusetyenziswa njengezinto zokwakha endaweni yesinyithi.
