I-pultrusionimathiriyeli edibeneyoI-polymer (FRP) i-high-performance fiber-reinforced polymer (FRP) i-composites eyenziwe kusetyenziswa inkqubo eqhubekayo eyaziwa ngokuba yi-pultrusion.

Kule nkqubo, iifibers eziqhubekayo (ezifana neglasi okanye i-carbon) zitsalwa kwibhafu ye-thermosetting resin (efana ne-epoxy resin, i-polyester, okanye i-vinyl ester), kwaye i-molds isetyenziselwa ukubumba izinto njengoko zifunwa. Emva koko intlaka iyaphilisa, yenze imveliso eyomeleleyo, ekhaphukhaphu, nehlala ixesha elide.

I-pultrusionIintlaka 

I-matrix resin yinxalenye ebalulekileyo yemathiriyeli edibeneyo ye-pultrusion. Iiresin eziqhelekileyo ze-Pultrusion ziquka i-epoxy, i-polyurethane, i-phenolic, i-vinyl ester, kunye neenkqubo ezisandul 'ukufundwa ze-thermoplastic resin. Ngenxa yeempawu ze-pultrusion composite materials, i-resin ye-matrix kufuneka ibe ne-viscosity ephantsi, amazinga okuphendula ngokukhawuleza kumaqondo aphezulu. Xa ukhetha i-matrix resin, izinto ezifana ne-pultrusion reaction rate kunye ne-resin viscosity kufuneka ziqwalaselwe. I-viscosity ephezulu inokuchaphazela umphumo we-lubrication ngexesha lokuvelisa imveliso.

I-Epoxy Resin 

Izinto ezihlanganisiweyo zePultrusion ezilungiselelwe nge-epoxy pultrusion resins zibonisa amandla aphezulu kwaye zinokusetyenziswa phantsi kweemeko zobushushu obuphezulu, ngokuphiliswa ngokukhawuleza.

isantya. Nangona kunjalo, imiceli mngeni efana nokonakala kwemathiriyeli, ixesha elifutshane lokusebenza, ukungenwa lula, kunye nobushushu obuphezulu bokunyanga bunciphisa uphuhliso loshishino lwamandla omoya e-China, ngakumbi kwincakuba yeinjini yomoya kunye nemathiriyeli yeengcambu.

Polyurethane 

I-polyurethane resin ine-viscosity ephantsi, evumela umxholo ophezulu weglasi wefiber xa kuthelekiswa ne-polyester okanye i-vinyl ester resins. Oku kubangela imathiriyeli edityanisiweyo ye-pultrusion polyurethane enemodyuli egobayo yokunwebeka kufutshane naleyo yealuminiyam. I-polyurethane ibonisa ukusebenza kakuhle kokusebenza xa kuthelekiswa nezinye iirasi.

Phenolic Resin 

Kwiminyaka yakutshanje, izinto ezidibeneyo ze-pultrusion ezisebenzisa i-phenolic resin ziye zafumana ingqwalasela ngenxa yetyhefu ephantsi, ukukhutshwa komsi ophantsi, ukuxhathisa amadangatye, kwaye zifumene izicelo kwiindawo ezinjengokuthuthwa koololiwe, amaqonga okugrumba ioyile elunxwemeni, iindibano zocweyo ezinganyangekiyo ngamachiza kunye nemibhobho. . Nangona kunjalo, impendulo yesiqhelo ye-phenolic resin yokunyanga iyacotha, ikhokelela kwimijikelo emide yokubumba, kunye nokwakheka kwamaqamza ngexesha lemveliso ekhawulezileyo eqhubekayo, echaphazela ukusebenza kwemveliso. Iinkqubo ze-Acid catalysis zihlala zisetyenziselwa ukoyisa le mingeni.

IVinyl Ester Resin 

I-Vinyl ester alcohol resin ineempawu ezibalaseleyo zoomatshini, ukumelana nobushushu, ukuxhathisa ukubola, kunye nokuphiliswa ngokukhawuleza. Malunga nonyaka ka-2000, yayiyenye yeereyini ezikhethwayo kwiimveliso zepultrusion.

I-Resin ye-Thermoplastic 

Iicomposites ze-Thermoplastic ziyoyisa imiqobo yokusingqongileyo ye-thermosetting composite, enikezela ukuguquguquka okunamandla, ukuchasana nempembelelo, ukunyamezela umonakalo omhle, kunye neempawu zokudambisa. Baxhathisa ukubola kweekhemikhali kunye nokusingqongileyo, banenkqubo yokunyanga ngokukhawuleza ngaphandle kweekhemikhali, kwaye banokucutshungulwa ngokukhawuleza. Iintlaka ze-thermoplastic eziqhelekileyo ziquka i-polypropylene, inayiloni, i-polysulfide, i-polyether ether ketone, i-polyethylene, kunye ne-polyamide.

Xa kuthelekiswa nemathiriyeli yemveli njengentsimbi, iiseramikhi, kunye neeplastiki ezingaqiniswanga, i-glass fibre-reinforced pultrusion composite zineengenelo ezininzi. Banobugcisa obukhethekileyo bokuyila ukuhlangabezana neemfuno ezithile zemveliso.
