intshayelelo

Njengoko ndiphonononga uphando lwee -Epoxy Resin Sheets , kuyacaca ukuba ukuqonda iimpawu zazo zokumelana nobushushu kubalulekile. Kweli nqaku, ndiza kuhlaziya iimpawu zokumelana nobushushu beeshiti, ndihlolisise ukubaluleka kwazo kwiindlela ezahlukeneyo zokusebenza kunye namashishini.

Ingcaciso emfutshane yaMaphepha kunye nokusetyenziswa kwawo

Amaphepha, akhiwe nge-epoxy resin kunye nezinto zokuqinisa, asetyenziswa ngokubanzi kumashishini ahlukeneyo. Ukuguquguquka kwazo kubenza babaluleke kakhulu kwizicelo ezisusela kulwakhiwo ukuya kwezobuchwephesha. La maphepha anika amandla akhethekileyo omatshini, ukugqunywa kombane, kunye nokumelana neekhemikhali, kubenza balungele iinjongo ezininzi.

Ukubaluleka kokuxhathisa koBuqondo kwizicelo ezahlukeneyo Ukuxhathisa ubushushu kubala okusisiseko kufezekiso kunye nobomi bemathiriyeli, ngakumbi kwizicelo ezifunyaniswe kumaqondo obushushu angaqhelekanga. Kumashishini anje ngenqwelomoya, imoto, kunye nehardware, imathiriyeli kufuneka imelane namaqondo obushushu amade ngaphandle kokubeka esichengeni uwiso lwazo oluncedisayo okanye ukuba luncedo. Amaphepha e-Epoxy tar, emva koko, kufuneka abe neempawu zokumelana nobushushu obanelisayo ukuhlangabezana nezicelo zezi zicelo.

 

Yintoni i-Epoxy Resin?

I-Epoxy tar yipolymer ethermosetting ethathwe kwimpendulo phakathi kwe-epichlorohydrin kunye ne-bisphenol-A. Eli laphu eliguquguqukayo linika uncamathiselo olukhulu, iipropathi zoomatshini, kunye nokumelana neekhemikhali, okwenza kube nengqiqo kwizicelo ezahlukeneyo. Ngokuqhelekileyo isetyenziswa njengesakhelo kwimathiriyeli edibeneyo, i-epoxy tar inika inkxaso esisiseko kunye nokhuseleko ngokuchasene nezinto zendalo. Inkcazo kunye noBumbeko Amaphepha e-tar epoxy ahlala equlunqwe nge-epoxy tar, i-fortification filaments (efana ne-fiberglass okanye i-carbon fiber), kunye nezinto ezongeziweyo. I-gum lattice inika ulwakhiwo oluyimfuneko, ngelixa izixhobo zokuxhasa ziphucula iipropati zoomatshini ezifana nomgangatho kunye nokuqina. Izinto ezongeziweyo zinokubandakanya izinto zokuzalisa, izithinteli-mlilo, okanye abasebenzi bokunyanga, ngokuxhomekeke kwiipropati ezifunwayo zento yokugqibela.

 

Izicelo eziqhelekileyo kumashishini afana noKwakha, i-Electronics, kunye ne-Aerospace

Ulwakhiwo: Njengamalungu olwakhiwo, izinto zokuncamathelisa, kunye nezaleko zezakhiwo, iibhulorho kunye neziseko zophuhliso.

I-Aerospace: Kwizixhobo zenqwelo-moya, ezifana neepaneli ze-fuselage, amaphiko, kunye nezakhiwo zangaphakathi, apho ukukhanya kunye namandla aphezulu kubalulekile.

 

Amagqabantshintshi eePropati zokuNxhathisa ubushushu

Ii-resin sheets ze-epoxy zinokumelana okumangalisayo nobushushu, nto leyo evumela ukuba zikwazi ukumelana nobushushu obahlukeneyo ngaphandle kokonakala okukhulu. Olu phawu lubalulekile ekugcineni ukuqina kwesakhiwo kunye nokusebenza kakuhle kwiindawo ezinobushushu obuphezulu.

Izinto eziPhembelela ukuxhathisa koBuqondo

Ukubunjwa kweMichiza: Ukwakhiwa kweekhemikhali ze-epoxy resin kunye nezongezo zichaphazela ukuzinza kwayo kwe-thermal kunye nokuchasana nobushushu.

Inkqubo yoNyango: Ukunyanga ngokufanelekileyo, kubandakanywa ubushushu kunye nobude, kubalulekile ekufezekiseni ukuxhathisa ubushushu obukhulu.

Ukuqiniswa: Uhlobo kunye nokuqhelaniswa kweefayili zokuqinisa zichaphazela i-thermal properties zamaphepha.

 

Ukuthelekisa kunye nezinye iintlobo zeeResins

Xa kuthelekiswa nezinye iintlobo zeerasi, ezifana ne-polyester okanye i-vinyl ester, i-epoxy resin inikezela ukuxhathisa ubushushu obuphezulu kunye nokuzinza kwe-dimensional. Ukukwazi kwayo ukugcina iipropathi zoomatshini kumaqondo obushushu aphakamileyo kuyibeka yodwa njengokhetho olukhethwayo kwizicelo ezifunayo.

 

Ukuqulunqwa kweMichiza ye-Epoxy Resin

Ukwakhiwa kweekhemikhali ze-epoxy resin kudlala indima ebalulekileyo ekunqumeni ukumelana nobushushu. I-epoxy resins enemisesane enevumba elimnandi kwisakhiwo semolekyuli ikholisa ukubonisa ukuzinza okuphezulu kwe-thermal xa kuthelekiswa ne-aliphatic epoxy resins. Ukongeza, ubukho bezongezo ezifana nezinzisi zobushushu okanye iiretardants zomlilo zinokonyusa ukumelana nobushushu bamaphepha.

 

Inkqubo yoNyango kunye noXinano lokuNxibelelana

Inkqubo yokunyanga ye-epoxy resin ibandakanya ukusabela kweekhemikhali phakathi kwe-resin kunye ne-agent ephilisayo, eyenza inethiwekhi edibeneyo. Ulawulo olululo lobushushu obunyangayo kunye nobude bexesha lubalulekile ekufezekiseni ukuxinana koqhagamshelo olufanelekileyo, oluchaphazela ngokuthe ngqo ukumelana nobushushu bemveliso yokugqibela. Ukunyanga okunganelanga kunokubangela ukuxhathisa ubushushu obuphantsi kunye nokuncipha kweempawu zoomatshini.

 

Iziqinisekiso kunye nezongezo

Ukufakwa kweefayili zokuqiniswa, ezifana ne-fiberglass okanye i-carbon fiber, iphakamisa iimpawu zemishini yamaphepha kunye negalelo ekuchaseni ukushisa. Ezi ziqinisekiso zisasaza uxinzelelo ngakumbi kwaye zibonelela ngamandla ongezelelweyo kumaqondo okushisa aphakamileyo. Ngaphaya koko, izongezo ezinje ngezizalisi ezinganyangekiyo kubushushu okanye i-ejenti ezomelezayo zinokuphucula ngakumbi ukumelana nobushushu kunye nokuqina kwee-epoxy resin composite.

 

Ubushushu beGass Transition (Tg) kunye nokubaluleka kwayo

Iqondo lobushushu beglasi (Tg) yiparameter ebaluleke kakhulu ebonisa utshintsho olusuka kwiglasi ukuya kwirubha kwiresin epoxy. Amaphepha abonisa ngokuqhelekileyo i-Tg ukusuka kwi-50 ° C ukuya kwi-200 ° C, kuxhomekeke ekubunjweni kunye neemeko zokuphilisa. I-Tg ephezulu ibonisa ukumelana nobushushu obungcono, njengoko izinto zihlala ziqinile kumaqondo okushisa aphakamileyo, ukunciphisa utshintsho lwe-dimensional kunye nokuguqulwa.

 

Ubushushu bokususwa kobushushu (HDT)

Ubushushu bokutshintsha ubushushu (HDT) liqondo lobushushu apho i-material deformer phantsi komthwalo ochaziweyo. Amaphepha abonisa amaxabiso e-HDT ukusuka kwi-100 ° C ukuya kwi-300 ° C, okwenza ukuba afanelekele izicelo ezivezwe ngokuphakathi ukuya kumaqondo aphezulu. Ukuqiniswa okufana ne-carbon fiber kunokunyusa kakhulu i-HDT ye-epoxy resin composites, ukwandisa usetyenziso lwazo kwiindawo ezifuna ukushisa.

 

I-Coefficient of Thermal Expansion (CTE)

I-coefficient of thermal expansion (CTE) ilinganisa utshintsho kwi-dimension yento kunye nokutshintsha kweqondo lokushisa. Amaphepha e-Epoxy abonisa amaxabiso aphantsi e-CTE, ebonisa utshintsho oluncinci kwiqondo lobushushu elibanzi. Le propati ibalulekile ekugcineni uzinzo lwe-dimensional kunye nokuthintela ukulwa okanye ukuphazamiseka kwizicelo zobushushu obuphezulu.

 

Usetyenziso lwaMashiti kwiNdawo zoBubushushu obuPhezulu

I-Aerospace kunye ne-Aircraft Components: Kumzi mveliso we-aerospace, amashiti asetyenziswa kakhulu ekwenzeni amacandelo eenqwelo-moya aphantsi kobushushu obugqithisileyo ngexesha lokubhabha. Ezi zixhobo ziquka iipaneli ze-fuselage, amaphiko, indawo yomsila, kunye nezakhiwo zangaphakathi. I-epoxy resin composites inika ibhalansi yobunzima, amandla aphezulu, kunye nokumelana nobushushu, igalelo ekusebenzeni ngokubanzi kunye nokhuseleko lwenqwelomoya.

Amacandelo ezeMoto: Kwicandelo leemoto, amashiti adlala indima ebalulekileyo ekwenziweni kwezinto ezahlukeneyo ezivezwe kubushushu be-injini, ukukhuhlana, kunye nezinto zokusingqongileyo. La malungu aquka iiphaneli zomzimba, iikhava ze-injini, ii-intake manifolds, kunye ne-brake systems. Ii-epoxy resin composites zibonelela ngokumelana nobushushu obugqwesileyo, ukhuseleko lokutya, kunye nokuzinza komda, ukuqinisa ukuthembeka kunye nokuqina kwamalungu emoto.

I-Electronics kunye nokufakelwa koMbane: Kwizicelo ze-elektroniki, amashiti asebenza njengezinto ezikhuselayo kwiibhodi zesekethe eziprintiweyo (iiPCB), iindawo ezivaliweyo zombane, kunye nezixhobo zesemiconductor. Ezi zixhobo zibonelela nge-thermal insulation, conductivity yombane, kunye nokukhuselwa kumswakama kunye nokungcola kwendalo. I-epoxy resin composites inikezela ukumelana nobushushu obuphezulu, iqinisekisa ukusebenza okuthembekileyo kweenkqubo ze-elektroniki kwiindawo ezifuna ukushisa.

 

Iindlela zoVavanyo lokuchasa ubushushu: Imigangatho ye-ASTM yoVavanyo lwaMashidi

I-American Society for Testing and Materials (ASTM) iseka iinkqubo ezisemgangathweni zokuvavanya iimpawu zokumelana nobushushu bamaphepha. Le migangatho ibandakanya i-ASTM D648 yokushisa ubushushu bokushisa (HDT), i-ASTM E831 yeqondo lokushisa lokutshintsha kweglasi (Tg), kunye ne-ASTM E228 ye-coefficient yokwandiswa kwe-thermal (CTE).
