Pultrusionihe mejupụtarabụ ngwakọta polymer (FRP) nke ejiri eriri rụọ ọrụ nke ọma nke e ji usoro a na-akpọ pultrusion arụ ọrụ.

N'ime usoro a, a na-adọpụta eriri ndị na-aga n'ihu (dịka iko ma ọ bụ carbon) site na ịsa ahụ nke resin thermosetting (dịka epoxy resin, polyester, ma ọ bụ vinyl ester), wee jiri ebu mee ihe iji kpụzie ihe ahụ dịka achọrọ. Resin ahụ na-agwọ, na-emepụta ngwaahịa siri ike, dị fechaa, ma sie ike.

PultrusionResin 

Resin matrix bụ akụkụ dị mkpa nke ihe mejupụtara pultrusion. Resin Pultrusion ndị a na-ahụkarị gụnyere epoxy, polyurethane, phenolic, vinyl ester, na sistemụ resin thermoplastic a na-amụ n'oge na-adịbeghị anya. N'ihi njirimara nke ihe mejupụtara pultrusion, resin matrix kwesịrị inwe obere viscosity, ọnụego mmeghachi omume ngwa ngwa na okpomọkụ dị elu. Mgbe ị na-ahọrọ resin matrix, a ga-atụle ihe ndị dị ka ọnụego mmeghachi omume pultrusion na viscosity resin. Nnukwu viscosity nwere ike imetụta mmetụta mmanụ n'oge nrụpụta ngwaahịa.

Resin Epoxy 

Ihe mejupụtara Pultrusion nke e ji epoxy pultrusion resins kwadebe na-egosi ike dị elu ma enwere ike iji ya n'ọnọdụ okpomọkụ dị elu, yana ọgwụgwọ ngwa ngwa.

Polyurethane 

Resin polyurethane nwere obere viscosity, nke na-eme ka eriri iko dị elu ma e jiri ya tụnyere resin polyester ma ọ bụ vinyl ester. Nke a na-eme ka ihe mejupụtara polyurethane pultrusion nwee modulus na-agbanwe agbanwe dị nso na nke aluminum. Polyurethane na-egosipụta arụmọrụ nhazi dị mma ma e jiri ya tụnyere resin ndị ọzọ.

Resin Fenolic 

N'afọ ndị na-adịbeghị anya, ihe mejupụtara pultrusion nke na-eji phenolic resin enwetawo nlebara anya n'ihi obere nsí ha, obere ikuku anwụrụ ọkụ, iguzogide ire ọkụ, ma achọtala ngwa ọrụ na mpaghara dịka njem ụgbọ okporo ígwè, ikpo okwu ịgba mmanụ n'ụsọ oké osimiri, ụlọ ọrụ kemịkalụ na-eguzogide nchara, na pipelines. Agbanyeghị, mmeghachi omume ọgwụgwọ phenolic resin ọdịnala na-adịghị nwayọ, na-ebute usoro ịkpụzi ogologo oge, na ịmepụta afụfụ n'oge mmepụta ngwa ngwa na-aga n'ihu, na-emetụta arụmọrụ ngwaahịa. A na-ejikarị sistemụ catalysis acid eme ihe iji merie ihe ịma aka ndị a.

Resin Vinyl Ester 

Vinyl ester alcohol resin nwere ezigbo ihe eji arụ ọrụ, iguzogide okpomọkụ, iguzogide nchara, na ọgwụgwọ ngwa ngwa. N'ihe dị ka afọ 2000, ọ bụ otu n'ime resins a kacha amasị maka ngwaahịa pultrusion.

Resin Thermoplastic 

Ngwakọta Thermoplastic na-emeri nsogbu gburugburu ebe obibi nke ngwakọta thermosetting, na-enye ike mgbanwe siri ike, iguzogide mmetụta, nnabata mmebi dị mma, na ihe ndị na-eme ka mmiri ghara ịdị. Ha na-eguzogide nchara kemịkalụ na gburugburu ebe obibi, na-enwe usoro ọgwụgwọ ngwa ngwa na-enweghị mmeghachi omume kemịkalụ, a pụkwara ịhazi ha ngwa ngwa. Resin thermoplastic a na-ahụkarị gụnyere polypropylene, naịlọn, polysulfide, polyether ether ketone, polyethylene, na polyamide.

Ma e jiri ya tụnyere ihe ndị e ji eme ihe dịka ígwè, seramiiki, na plastik ndị a na-anaghị eme ka ha sie ike, ihe ndị e ji iko mee nke e ji eriri mee nwere ọtụtụ uru. Ha nwere ikike imewe pụrụ iche iji mezuo ihe achọrọ maka ngwaahịa.
