Kuphulikazinthu zophatikizandi ma polymer amphamvu kwambiri a fiber-reinforced polymer (FRP) opangidwa pogwiritsa ntchito njira yopitilira yotchedwa pultrusion.

Pochita izi, ulusi wosalekeza (monga galasi kapena kaboni) umakokedwa kudzera mu bafa la thermosetting resin (monga epoxy resin, polyester, kapena vinyl ester), ndiyeno nkhungu zimagwiritsidwa ntchito popanga zinthu monga momwe zimafunira. Utotowo umachira, n’kupanga chinthu cholimba, chopepuka komanso cholimba.

KuphulikaMa resin 

Utomoni wa matrix ndi gawo lofunikira kwambiri lazinthu zophatikizika za pultrusion. Common Pultrusion resins amaphatikiza epoxy, polyurethane, phenolic, vinyl ester, ndi machitidwe omwe aphunziridwa posachedwa kwambiri a thermoplastic resin. Chifukwa cha mawonekedwe a zida zophatikizika za pultrusion, utomoni wa matrix uyenera kukhala ndi kukhuthala kotsika, kuthamanga kwachangu pakutentha kwambiri. Posankha utomoni wa matrix, zinthu monga pultrusion reaction rate ndi resin viscosity ziyenera kuganiziridwa. Mkulu mamasukidwe akayendedwe angakhudze kondomu zotsatira pa kupanga mankhwala.

Epoxy Resin 

Zida zophatikizika za pultrusion zokonzedwa ndi epoxy pultrusion resins zimawonetsa mphamvu zambiri ndipo zitha kugwiritsidwa ntchito potentha kwambiri, ndikuchiritsa mwachangu.

liwiro. Komabe, zovuta monga kuwonongeka kwa zinthu, nthawi yayifupi yogwiritsira ntchito, kusalowerera bwino, komanso kutentha kwambiri kumachepetsa kukula kwa mafakitale amagetsi ku China, makamaka pa tsamba la turbine ndi mizu.

Polyurethane 

Utoto wa polyurethane uli ndi kukhuthala kotsika, zomwe zimapangitsa kuti magalasi azikhala apamwamba kwambiri poyerekeza ndi ma polyester kapena vinyl ester resins. Izi zimabweretsa pultrusion polyurethane composite zida zomwe zimakhala ndi modulus yopindika pafupi ndi ya aluminiyamu. Polyurethane imawonetsa ntchito yabwino kwambiri yosinthira poyerekeza ndi utomoni wina.

Phenolic Resin 

M'zaka zaposachedwa, zida zophatikizika za pultrusion zogwiritsa ntchito phenolic resin zakhala zikudziwika chifukwa cha kawopsedwe kakang'ono, utsi wochepa, kukana kwa malawi, ndipo zapeza ntchito m'malo monga mayendedwe a njanji, nsanja zobowola mafuta akunyanja, malo ochitira zinthu zolimbana ndi dzimbiri, ndi mapaipi. Komabe, machitidwe achikhalidwe a phenolic utomoni amachiritsa pang'onopang'ono, zomwe zimapangitsa kuti azizungulira nthawi yayitali, komanso mapangidwe a thovu popanga mosalekeza, zomwe zimakhudza magwiridwe antchito. Njira zochepetsera acid nthawi zambiri zimagwiritsidwa ntchito kuthana ndi zovuta izi.

Vinyl Ester Resin 

Vinyl ester alcohol resin imakhala ndi zida zabwino zamakina, kukana kutentha, kukana dzimbiri, komanso kuchiritsa mwachangu. Chakumapeto kwa chaka cha 2000, inali imodzi mwazinthu zomwe zimakondedwa kwambiri ndi zinthu za pultrusion.

Thermoplastic resin 

Ma composites a Thermoplastic amalimbana ndi zovuta zachilengedwe zamagulu opangira ma thermosetting, omwe amapereka kusinthasintha kwamphamvu, kukana kukhudzidwa, kulolerana kwabwino kwa kuwonongeka, komanso kunyowetsa katundu. Amakana dzimbiri ndi mankhwala komanso chilengedwe, amakhala ndi njira yochizira mwachangu popanda kukhudzidwa ndi mankhwala, ndipo amatha kukonzedwa mwachangu. Ma resins ambiri a thermoplastic amaphatikizapo polypropylene, nayiloni, polysulfide, polyether ether ketone, polyethylene, ndi polyamide.

Poyerekeza ndi zida zachikhalidwe monga zitsulo, zoumba, ndi mapulasitiki osalimbitsa, magalasi opangidwa ndi pultrusion composites ali ndi zabwino zingapo. Iwo ali ndi luso lapadera la mapangidwe kuti akwaniritse zofunikira zamtundu wina.

Ubwino waKuphulikaZinthu Zophatikizika:

1.Kupanga Kuchita Bwino: Kujambula kwa pultrusion ndi njira yosalekeza yokhala ndi ubwino monga kuchuluka kwa kupanga, kutsika mtengo, komanso nthawi yobweretsera mofulumira poyerekeza ndi njira zina zopangira zopangira.

2.High Strength-to-weight Ratio: Zida zophatikizika za pultrusion ndizolimba komanso zolimba koma zopepuka. Carbon fiber Pultrussion ndi yopepuka kwambiri kuposa zitsulo ndi zida zina, zomwe zimawapangitsa kukhala oyenera kugwiritsa ntchito potengera kulemera kwa ndege, magalimoto, ndi zoyendera.

Kukaniza kwa 3.Corrosion Resistance: FRP composites imawonetsa kukana kwamphamvu kwa dzimbiri, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito m'mafakitale monga kukonza mankhwala, m'madzi, petroleum, ndi gasi.

4.Electrical Insulation: Magalasi opangira magalasi amatha kupangidwa kuti asakhale oyendetsa, kuwapanga kukhala abwino kwa magetsi omwe amafunikira dielectric performance.
Kukhazikika kwa Dimensional: Zida zophatikizika za pultrusion sizimapunduka kapena kusweka pakapita nthawi, zomwe ndizofunikira kwambiri pamapulogalamu omwe amalekerera ndendende.

5.Mapangidwe Amakonda: Zigawo za pultrusion zimatha kupangidwa mosiyanasiyana ndi kukula kwake, kuphatikizapo ndodo, machubu, matabwa, ndi mbiri zovuta kwambiri. Ndiwosinthika mwamakonda, kulola kusiyanasiyana kwamapangidwe amtundu wa fiber, voliyumu ya utomoni, mtundu wa utomoni, chophimba chakumtunda, ndi chithandizo kuti chikwaniritse magwiridwe antchito ndi zofunikira pakugwiritsa ntchito.

Kuipa kwa Kugwiritsa NtchitopultrusionZophatikiza:

1.Mawonekedwe Ochepa a Geometric: Zida zophatikizika za pultrusion zimangokhala ndi zigawo zomwe zimakhala ndi magawo okhazikika kapena pafupifupi nthawi zonse chifukwa chakupanga kosalekeza komwe zinthu zolimbitsa fiber zimakokedwa kudzera mu nkhungu.

2.Njira Zapamwamba Zopangira: Zomwe zimagwiritsidwa ntchito popanga pultrusion zingakhale zodula. Ayenera kupangidwa kuchokera ku zipangizo zamtengo wapatali zomwe zimatha kupirira kutentha ndi kupanikizika kwa ndondomeko ya pultrusion, ndipo ziyenera kupangidwa ndi kulolerana kwakukulu kwa Machining.

3.Low Transverse Strength: Mphamvu yodutsa ya pultrusion composite materials ndi yochepa kusiyana ndi mphamvu yautali, yomwe imawapangitsa kukhala ofooka mu njira yopita ku ulusi. Izi zitha kuthetsedwa pophatikiza nsalu zamitundu yambiri kapena ulusi panthawi ya pultrusion.

4.Kukonza Kovuta: Ngati zida za pultrusion zawonongeka, kukonza kungakhale kovuta. Zigawo zonse zingafunike kusinthidwa, zomwe zingakhale zodula komanso zowononga nthawi.

Mapulogalamu aKuphulikaZinthu ZophatikizikapultrusionZida zophatikizika zimapeza ntchito zambiri m'mafakitale osiyanasiyana, kuphatikiza:

1.Azamlengalenga: Zida za ndege ndi zapamlengalenga, monga malo owongolera, zida zoyikira, ndi zothandizira zamapangidwe.

2.Magalimoto: Zida zamagalimoto, kuphatikiza ma shafts, ma bumpers, ndi zida zoyimitsidwa.

3.Infrastructure: Kulimbikitsa ndi zigawo za zomangamanga, monga zogona, zosungiramo milatho, kukonza konkire ndi kulimbikitsa, mizati yothandizira, zotetezera magetsi, ndi zida zodutsa.

4.Chemical Processing: Zida zopangira mankhwala monga mapaipi ndi ma gratings pansi.

Zachipatala: Kulimbitsa ma braces ndi ma endoscopic probe shafts.

5.Marine: Ntchito zapamadzi, kuphatikiza masts, battens, ma doko, ma pin, ndi ma docks.

6.Mafuta ndi Gasi: Ntchito zamafuta ndi gasi, kuphatikiza zitsime, mapaipi, ndodo zamapope, ndi nsanja.

7.Mphepo Yamphamvu: Zigawo za masamba opangira turbine, monga ma reinforcements a blade, spar caps, ndi zouma mizu.

8.Zida Zamasewera: Zida zomwe zimafunikira magawo opitilira malire, monga ma skis, ma ski pole, zida za gofu, zopalasa, zida zoponya mivi, ndi mitengo yamahema.

Poyerekeza ndi zitsulo zachikhalidwe ndi mapulasitiki, zida zophatikizika za Pultrusion zimapereka zabwino zambiri. Ngati ndinu mainjiniya azinthu omwe akufunafuna zida zophatikizika kwambiri zomwe mungagwiritse ntchito, zida zophatikizika za Pultrusion ndizosankha bwino.
