Izinto eziphambili zezinto ezidibeneyo ziyi-fiber kunye ne-resin.I-fiber ngokuqhelekileyo i-glass okanye i-carbon fiber, zombini ezo zomeleza amandla kunye nokuqina okufunekayo kwimveliso.Nangona kunjalo, ukuba isetyenziswe yodwa, ayinako ukuhlangabezana nokusebenza kokugqibela kwemveliso. Ifakwe kwi-resins kwaye emva koko yanyangwa, iifayibha ziyahlangabezana nokomelela, ukuqina kunye neemfuno ezikhaphukhaphu zoyilo loyilo lwesicelo, ngelixa ukongeza izibonelelo ezininzi kwimveliso yokugqibela.
I-resin ye-polyester engasetyenziswanga ingasetyenziselwa ukuthutha, isakhiwo kunye nokuphuhliswa kweeprofayili zokwakha
Xa kuziwa kwii-resins, kukho ukhetho oluninzi, kwaye unokukhetha kwakhona izongezo ze-resin ukuhlangabezana neemfuno zakho zesicelo.Ngoko ke, kubaluleke kakhulu ukuqonda ukuhlukana phakathi kwee-resins kunye nendlela ezichaphazela ngayo iipropati ze-composites.
Ukongezwa kwizinto ezikhoyo
Zonke izinto ezidibeneyo, kodwa zinenzuzo efanayo: amandla aphezulu, ukuqina kunye nokuxhathisa ubunzima obulula kunye nemeko engcono. iimpawu eziphambili ze-composite kufuneka zibe.
Eyona ndlela ingabizi kakhulu yokwenza ama-composites alula kukusebenzisa i-polyester resins engaxutywanga.Le resin inomatshini, umbane kunye neekhemikhali ezintle kwaye inokulungelelaniswa kuluhlu lwezicelo eziqhelekileyo ezifana nokuthutha, izakhiwo kunye neeprofayili zokwakha.
NGATHI
hebei Yuniu Fiberglass Manufacturing Co., LTD.Ubukhulu becala sivelisa kwaye sithengise iimveliso ze-e-type fiberglass, ezifana ne-fiberglass roving, i-fiberglass yesilika enqunqiweyo, i-fiberglass eqoshiwe, i-fiberglass gingham, ivakalelwa ngenaliti, ilaphu le-fiberglass kunye nokunye.Ukuba naziphi na iimfuno, nceda uqhagamshelane nathi ngokukhululekileyo.
Nangona kunjalo, ukuba ukuqina okuphezulu okanye amandla afunekayo, ngoko i-epoxy ngokungangabazeki iyona nto ingcono kakhulu.Ubudlelwane phakathi kwe-epoxy kunye neentambo zomelele, oku kuthetha ukuba imithwalo ephezulu ye-shear inokudluliselwa phakathi kweefayili, inika i-composite ixabiso eliphezulu lamandla. kunye nomxholo ophezulu wefayibha ovunyelwe yi-epoxy resins, i-composites enamandla abalaseleyo kunye nokuqina okuphezulu kunokwenziwa kwaye kulungiswe ngakumbi ukuze kuhambelane nezicelo zobushushu obuphezulu xa kuyimfuneko.
Ukongeza, ukuba i-composite idinga ukuchasana neendawo ezinzima ngaphezu kobunzima, i-vinyl esters ingaba yinto engcono kakhulu.Isakhiwo se-molecular ye-vinyl esters sichasene neekhemikhali, ngoko ke ukusetyenziswa kwe-vinyl esters kuya kuphucula ukusebenza kwee-composites ukuba zenzelwe ukusetyenziswa kwiindawo zaseLwandle okanye izicelo zoshishino apho i-acids okanye iziseko zikhona.
Kwimveliso yeeprofayili ezidibeneyo ezifunekayo ukuba zihlanganiswe kunye nezikrini, i-composite kufuneka ibe yomelele kwaye ithintele ukuqhekeka kunye nokuphuka.Oku kunokufezekiswa ngokuqulunqwa kwesakhiwo, kodwa ukukhetha i-resin efanelekileyo kunokwenza lula isakhiwo kunye nokunciphisa iindleko, okwenza i-composite ilungele uluhlu olubanzi lwezicelo.Umzekelo, iipolyurethanes zinokuqina okuphezulu kakhulu xa kuthelekiswa neepolyester ezingafakwanga, zizenza zilungele usetyenziso olunjalo.
Ukongeza iimpawu ezintsha
Ukukhetha i-resin ehambelana nezona mpawu zixabisekileyo ze-composite ziya kuphucula ukusebenza kunye nobomi be-composite.Nangona kunjalo, ukuthatha ixesha lokukhetha i-resin kuya kukunika inzuzo eninzi kunokuphucula iipropati ezikhoyo.
Iiresin zinokongeza iipropathi ezintsha ngokupheleleyo kwiimveliso ezidibeneyo.Izongezo ze-resin zinokongezwa kwii-resin ukuphumeza uluhlu lweenzuzo ukusuka kuphuculo olulula ekugqityweni komphezulu okanye umbala ukuya kwizixhasi ezintsonkothileyo ezifana ne-uv, i-antibacterial, okanye i-antiviral properties.
Umzekelo, ngenxa yokuba iiresin zibola ngokwendalo xa zibekwe kukukhanya kwelanga, ukongeza izinto zokufunxa imitha ye-UV zikwazi ukwenza imidibaniso ukuba ifezekise ukusebenza kakuhle kwindawo enokukhanya okuphezulu, nto leyo edla ngokukhokelela ekubhimbeni kunye nokuqhekeka kwezinto.
Ngokufanayo, izongezo ze-antibacterial zingaxutywa kwi-resin ukukhusela ukungcoliswa kwebhaktheriya okanye i-fungal.Oku kuluncedo kuyo nayiphi na imveliso edityanisiweyo ebandakanya ukuguqulwa ngesandla, njengoomatshini, izithuthi zikawonke-wonke, kunye nezixhobo zonyango.
Ezinye iziphumo zangaphandle
Kuyafaneleka ukuba uqaphele ukuba kwezinye iimeko, ukongezwa kwezongezo ze-resin kunokutshintsha iipropati ze-composites.Kwezinye iimeko ezigqithisileyo, umzekelo, izixa ezikhulu zezongezo ze-flame retardant ziyafuneka ukuze zisebenze ngokufanelekileyo.Ngeli xesha, inani leefayili kwi-composite kufuneka lincitshiswe, libangele ukunciphisa okuhambelanayo kumandla kunye nokuqina.
Ukukhethwa kwe-resin yinxalenye ebalulekileyo yoyilo olupheleleyo lwezinto ezidibeneyo kwaye akufanele zihoywe.Isisombululo esona sisombululo kukuchonga iimpawu ezinqwenelekayo zezinto ezidibeneyo, ukudibanisa i-resin efanelekileyo yokuphucula ezi zakhiwo, kwaye uthathele ingqalelo ibhalansi phakathi kwefiber kunye ne-resin.
