The pultrusion molding process is extrude the continue glass fiber bundle impregnated with resin glue uye zvimwe zvinoramba zvichisimbisa zvinhu zvakadai segirazi jira tepi, polyester pamusoro wakanzwa, etc. Nzira yekugadzira girazi faibha yakasimbisa epurasitiki profiles nekupisa kurapa muchoto chinoporesa.Iyo inozivikanwawo seinoenderera mberi pultrusion process.Iyo huru yekugadzira mapaipi, tsvimbo, profiles, mahwendefa uye mamwe magirazi fiber akasimbisa mapurasitiki.
Zvakanakira iyo pultrusion molding process ndeiyi: midziyo yakapusa, mutengo wakaderera, kugadzirwa kwakakwira, nyore kuumba otomatiki mutsara wekugadzira, uye yakagadzikana chigadzirwa mhando;inogona kupa kutamba kwakazara kune basa rekusimbisa zvinhu, yakakwirira mechanical zvivakwa, kunyanya longitudinal simba uye modulus;kushandiswa kunobudirira kwezvinhu zvakasvibirira High rate, chaizvoizvo hapana marara emakona;iyo longitudinal uye inochinjika simba reiyo mbiri inogona kugadziriswa kuti ienderane nezvinodiwa zvakasiyana zvekushandisa;kureba kwayo kunogona kutemwa sezvinodiwa.
Mishonga inoshandiswa zvakanyanya muzvigadzirwa zvakasvibiswa ndeye unsaturated polyester resins, inoteverwa ne epoxy resins, iyo inonyanya kushandiswa kune zvigadzirwa zvine high mechanical properties uye zvinodiwa kupisa kupisa, kuwedzera kune vinyl ester resins, phenolic resins, thermoplastic resins, nezvimwewo. iyo pultrusion molding process ye resin glue ndeiyi: yakaderera viscosity, nyore kupinda mukati mekusimbisa zvinhu;nguva yakareba gel (inowanzodiwa kushandisa maawa anopfuura 8), kukurumidza kuporesa, kusangana nezvinodiwa zvekuenderera mberi kuumbwa;kunamatira kwakanaka, Iyo inorapa shrinkage idiki;kuchinjika kwakanaka, uye chigadzirwa hachisi nyore kutsemuka.
Kushandiswa kwe epoxy resin composite pultrusion profile
Epoxy resin composite pultrusion zvigadzirwa zvinonyanya kushandiswa kune:
1) Nzvimbo yemagetsi parizvino ndiyo inonyanya kushandiswa munda uye imwe yezvinotariswa zvebudiriro.Zvakadai se transformer air duct positioning rods, high-voltage insulator mandrels, high-voltage cable dziviriro machubhu, cable racks, insulating manera, insulating tsvimbo, mapango, track guard, cable distribution racks, motor parts, etc.
2) Munda wemakemikari anticorrosion ndiyo inokurumidza kukura munda mumakore achangopfuura.Zvigadzirwa zvakajairika zvinosanganisira: pombi network inotsigira zvimiro, sucker tsvimbo, downhole pressure pombi, wastewater treatment equipment, chemical baffles, railings, stairs, platform handrails, grille floors, etc. mumakemikari, petroleum, bepa, metallurgy uye mamwe mafekitari.
3) Mumunda wekuvaka dhizaini, inonyanya kushandiswa kune chiedza chimiro, superstructure yepamusoro-soro chimiro kana chakakosha chinangwa chimiro.Zvakadai semugadzirirwo wekamuri inofambiswa, maprofiles emusuwo nemahwindo zvimiro, matrusses, mabhiriji akareruka, njanji, mabhuraketi ematende, sirin'i zvimiro, hombe boron zvimiro, nezvimwe.
4), nhandare dzemitambo uye dzevaraidzo dzakadai setsvimbo dzekuredza, tsvimbo dzehockey, mabhodhi echando, matanda evhavha, uta nemiseve, nezvimwe.
5) Minda yekufambisa senge mareki emota, marori mafuremu, ngoro dzefiriji, mabhodhoro emota, mabhegi ekutakura, mabumpers, dhizaini, magetsi echitima track guard, nezvimwe.
6) Mumunda wesimba, inonyanya kushandiswa kune solar collector brackets, wind turbine blades, uye mafuta etsime conduits.
7) Mumunda wemuchadenga, senge ndege uye spacecraft antenna insulation pombi, mota zvikamu zve spacecraft, ndege inoumba I-matanda, matanda emugero uye masikweya matanda, tambo dzendege, matanda ekubatanidza, nezvimwe.
