Rigid foam core material Inomiririra zvigadzirwa, mabhizinesi uye hunyanzvi hwekushandisa polyurethane, phenolic resin, PET, PVC, SAN, PES uye zvimwe zvinhu zvefuro.

Rigid foam core material Inomiririra zvigadzirwa, mabhizinesi uye hunyanzvi hwekushandisa polyurethane, phenolic resin, PET, PVC, SAN, PES uye zvimwe zvinhu zvefuro.

Chimiro chefuro musimboti chinhu chakaumbwa, kazhinji thermoset polymer (asi inogona kunge iri thermoplastic) yakasanganiswa neinert yemuviri gasi (senge nitrogen) kana kemikari inofuridza panguva yekuumbwa.Mhedzisiro yacho haisi yakasimba zvinhu, asi yakaderera-density microcellular foam yakasanganiswa nepamusoro-density shell.

Iyo foam musimboti inoderedza huremu hwese hwezvinhu, ukuwo ganda rakasimba richiita kuti ive yakasimba uye isingaite.Chimiro chechinyorwa chinofanana nesangweji, ine yakaderera-density musimboti wakakomberedzwa nepamusoro-density ganda.Nekuda kwekusiyana kwayo kwepakati magadzirirwo, akaomesesa foam cores anowanzo kuita 20% kusvika 40% kureruka pane akasimba mapolymer, aruminiyamu, simbi, sheet molding compound, kana zvimwe zvinowanzoshandiswa.Nekuda kwehunhu hwayo husina kusimba, zvigadziko zvinoshandiswa kugadzira mafuro ezvimiro zvinowanzove thermoplastic polymers kwete thermosets.Inowanzo shandiswa thermoplastics inosanganisira, asi haigumiri ku: polyurethane, polycarbonate, polyphenylene ether (Noryl), polybutylene terephthalate (Valox) uye acrylonitrile butadiene styrene uye mamwe furo core zvinhu: polyurethane, phenolic Resin, PET, PVC, SAN, PES foam zvigadzirwa, mabhizinesi uye maapplication matsva.

Polyurethane foam musimboti inogadzirwa kubva kuCFC yemahara foamed polyurethane, yakavharwa sero musimboti iyo inogona kugadzira kumeso, mabhodhi uye tsika zvigadzirwa zveakasiyana density uye ukobvu, ukuwo hurefu hwakanyanya, murazvo unodzoreredza akaomesesa polyurethane foam sheets Huni, zvidhinha kana moldings zviripo zvakare.Inodhura-inoshanda, inoshanda uye yakasimba.Nepo zvimiro zve polyurethane foam cores zvingave zvisina kukodzera kune zvakanyanya kudikanwa maapplication, anoshandiswa zvakanyanya kuwedzera ukobvu, kugadzira muchinjika-chikamu chimiro, insulating mhando, uye flotation.

Polyurethane foam cores isarudzo yakaderera-yakanyanya kune vanogadzira vanogadzira.Rigid polyurethane foam inoshandiswa pakuyangarara, kuvharisa kana sechinhu chepakati senge kuwedzera marimu emugungwa, mahull uye mamwe maapplication emugungwa.
