Chii chinonzi Acrylic impact modifier?

Impact modifier imhando yemakemikari inogona kuvandudza yakadzika tembiricha embrittlement yezvinhu zvepolymer uye kuvapa kusimba kwepamusoro.

Features

Basa guru rekugadzirisa shanduko nderekuvandudza kudzika-tembiricha brittleness yezvinhu zvepolymer uye kuvapa kuoma kwepamusoro.Sekureva kwemushumo weAmerican Plastics Industry Consulting Company, musika wepasi rose wepasi rose wepasi rose wekuchinja kwepurasitiki muna 2004 waive 600000 matani (ine mutengo wemusika ungangoita bhiriyoni imwe nemazana mashanu emadhora), ayo ma styrene copolymers akadai seABS uye methyl methacrylate butadiene styrene ( MBS) yakava chikamu chikuru chezvigadziriso zvinogadzirisa, zvichiverengera nezve 45% yemugove wemusika, uye acrylic acids akaverengera angangoita 30%;Elastomers, kusanganisira EPDM uye thermoplastic elastomer (TPE), inosvika gumi muzana yemugove wemusika;Chlorinated polyethylene (CPE) inoita 10%, uye vamwe vanotora 5%.Zvinofungidzirwa kuti avhareji yekukura kwepagore ye styrene impact modifiers ichave isingasviki 3% kubva 2004 kusvika 2009, nepo avhareji yekukura kwemamwe marudzi ichave 5% - 6%.Sezvo PVC iriyo inonyanya kushandiswa mhando yekukanganisa gadziriso, inoverengera inosvika makumi masere muzana muzana yedosi, kuwedzera kwePVC kudiwa kuchafambisawo kuwedzera kwekuda kwekukanganisa kugadzirisa.Mainjiniya epurasitiki resin akadai sePC, polyamide (PA), polyester, nezvimwewo zvinopedza chikamu gumi kubva muzana chezvinogadzirisa zvinogadzirisa.Sezvo kudiwa kwemapurasitiki einjiniya kuri kukura zvakanyanya, mashandisirwo emagetsi ekugadzirisa ari kuwedzera.Polyolefin resin inodya inenge 10% yekuchinja kwekuchinja.Vanamazvikokota vakaratidza kuti maitiro ekuvandudza ezvigadziriso zvinogadzirisa mune ramangwana kuita zvirinani, mutengo wakachipa, kukurumidza kuita, uye zvinhu zvakatetepa padanho rekuvandudza mashandiro ezvishandiso zvikuru kana kuve nechokwadi chekuita.Pakati pemakambani ekunze, akadai seArkema's Durastrength chigadzirwa chinogona kuvandudza zvakanyanya kupikisa kwePVC.Pamusoro pezvo, Compton, DuPont, Dow Chemical nemamwe makambani vakatangisa zvigadzirwa zvavo zvinoshanda.

Indasitiri mamiriro

Parizvino, makambani anogadzira magadzirirwo ekugadzirisa, kunyanya ACR neMBS vagadziri, vanodzidzira tekinoroji monopoly, havatambise tekinoroji, uye vanomisikidza mafekitori ega kana akabatana muAsia padyo nenzvimbo yemusika, kuti vatore musika ungangoita.Mune ramangwana, ACR neMBS ndiwo maviri makuru emhando dzekugadzirisa magadzirirwo munyika.Pamusoro pekugadziriswa kwePVC, magadzirirwo ekugadzirisa ari kuwedzerwa kuPC, PBT, naironi, ABS uye mamwe marezeni ekuvandudza mashandiro ekugadzirisa uye simba rekuita.

type

Mhando huru dzePVC impact modifiers dzinosanganisira chlorinated polyethylene (CPE), methyl methacrylate butadiene styrene copolymer (MBS), acrylonitrile butadiene styrene copolymer (ABS), EVA, ACR, acrylonitrile butadiene random copolymer (NBR) uye rigid particles.

effect

Zvigadzirwa zvayo zvemuchina zviri nani pane zveLDPE, uye nzvimbo yekunyunguduka yakakwira kupfuura yeLDPE, ingangoita 126 136 ℃.Embrittlement yayo inonyanya kushandiswa sechigadziriso chePVC kuvandudza mhedzisiro yayo kuramba.CPE pachayo zvakare.
