Maitiro ekuvandudza kupararira kwezvinodzivisa moto

Nekushandiswa kwakakura kwezvinhu zvepolymer uye zvigadzirwa zvemagetsi zvinoshandiswa nevanhu muhupenyu hwezuva nezuva, kuwanda kwemoto kuri kuwedzerawo, uye kukuvara kwazvinoita kuri kutotyisa. Kushanda kwezvinhu zvepolymer zvinodzivirira moto kwave kukosha zvakanyanya, kuitira kuzadzisa zvinodiwa zvepurasitiki nezvigadzirwa zverabha, kuderedza kusvibiswa kweguruva kunokonzerwa nezvinhu zvinodzivirira moto, masterbatch inodzivisa moto yakavapo, uye inoita basa rinokosha pakuumbwa kwezvigadzirwa zvekupedzisira.

Masterbatch inodzivisa moto inogadzirwa nenzira inonzwisisika, kuburikidza nekusanganiswa kwe organic kwe flame retardant, lubricant dispersant uye carrier, kuburikidza nekunatswa kwakasimba, kusanganisa, kufanana uye ipapo extrusion granulation. Muizvi, dispersant inoita basa rakakosha, kuwedzera chikamu che dispersant kunogona kubatsira zvikuru kukurudzira kupararira kwe flame retardant, kuitira kuti zvive nyore kupararira zvakaenzana mukuita, kudzivirira agglomeration ye flame retardant, zviri nani kuparadzira mhedzisiro, kuitira kuti mamorekuru anodzivisa moto aite zviri nani flame retardant effect, nokudaro zvichivandudza kushanda kwe flame retardant yepurasitiki, zvigadzirwa zve rabha, moto uchadzipwa pakutanga.

Zvisinei, mukuita, mapurasitiki mazhinji nezvikamu zverabha zvine zvikamu zvinodzivirira moto hazvikwanise kuita mabasa azvo ekudzivirira moto nekuda kwekupararira kusina kuenzana kwezvinodzivirira moto muchinhu chiri mumoto, izvo zvinoguma nemoto mukuru uye kurasikirwa kukuru.

Kuti zvikurudzire kupararira kwakafanana kwezvinodzivisa moto kana masterbatch inodzivirira moto mukugadzirwa kwechigadzirwa, kuderedza kuitika kwekupararira kusina kuenzana kunokonzerwa nemhedzisiro yekudzivisa moto isingagone kushandiswa zvakanaka, nezvimwewo, uye kuvandudza mhando yezvigadzirwa zvinodzivisa moto, SILIKE yakagadzira SILIMER hyperdispersant yakagadziriswa silicone.

SILIMER rudzi rwe tri-block copolymerized modified siloxane inoumbwa nema polysiloxanes, mapoka e polar uye mapoka e long carbon chain. Zvikamu zve polysiloxane cheni zvinogona kutamba basa rakati resolation pakati pema flame retardant molecules pasi pe mechanical shear, zvichidzivirira secondary agglomeration yema flame retardant molecules; zvikamu zve polar group cheni zvine connection ne flame retardant, zvichiita basa re coupling; zvikamu zve long carbon chain zvine compatibility yakanaka kwazvo ne base material.

Zvigadzirwa izvi zvakakodzera maresini ethermoplastic akajairika, TPE, TPU nedzimwe elastomers dzethermoplastic, uye zvinogona kuvandudza kuenderana pakati pemapigment/filler powders/functional powders uye resin systems, uye kuchengetedza mamiriro ekupararira kwehupfu hwakagadzikana.

Panguva imwe chete, inogonawo kuderedza viscosity yekunyunguduka, kuderedza torque ye extruder, kumanikidzwa kwe extrusion, kuvandudza mashandiro ekugadzirisa echinhu, ne lubrication yakanaka yekugadzirisa, uye panguva imwe chete inogona kuvandudza zvinobudirira kunzwa kwechinhu, nekunaka uye haikanganisi hunhu hwemuchina hwechinhu, ndeyekusimudzira kupararira kwakafanana kwezvikamu zvinodzora moto kuti ikurudzire mugumisiro wemumoto unodzora mugumisiro wekupedzisira wezvigadzirwa kuti upe mhinduro dzemhando yepamusoro.

Pamusoro pezvo, zvigadzirwa izvi hazvina kukodzera chete kune masterbatch inodzivirira moto, asiwo kune masterbatch yemavara kana zvinhu zvakapararira zvakanyanya.
