Iyi yekuwedzera yemafuta inogadzirwa zvakanyanya kugadzira nekugadzirwa kwePE nePP WPC (mapuranga epurasitiki zvinhu) senge WPC decking, WPC fenzi, uye mamwe maWPC macomposites, nezvimwe. Iyo yakakosha chikamu chechigadzirwa ichi yakagadziridzwa copolysiloxane, iyo ine polar inoshanda. mapoka, uye ane kuenderana kwakanaka neresin nehupfu yehuni. Inogona kuvandudza kupararira kwehuni yehuni panguva yekugadzira uye kugadzirwa, pasina kukanganisa maitiro ekuenderana kwevanopindirana muhurongwa, uye inogona kunyatsovandudza michina yezvigadzirwa. Ichi chigadzirwa chine mutengo wakakwira kuita, yakanakisa lubrication maitiro, inogona kuvandudza matrix resin kugadzirisa zvivakwa, asi zvakare inogona kuita kuti chigadzirwa chiite mushe.

1) Kuvandudza kugadzirisa, kuderedza extruder torque, kunatsiridza kupararira kwekuzadza;
2) Yemukati & yekunze lubricant yeWPC, kuderedza kushandiswa kwesimba uye kuwedzera kugadzirwa kwakanaka;
3) Kugarisana kwakanaka nehupfu hwehuni, haikanganisi masimba pakati pemamorekuru emapuranga epurasitiki anoumba uye anochengetedza mechanical properties ye substrate pachayo;
4) Deredza huwandu hwekuenderana, kuderedza kukanganisa kwechigadzirwa, kunatsiridza kutaridzika kwezvigadzirwa zvepurasitiki zvehuni;
5) Hapana kunaya mushure mekubikira bvunzo, chengetedza kwenguva refu yakatsetseka.
Kuwedzera mazinga ari pakati pe2.0 ~ 3.5% anokurudzirwa. Inogona kushandiswa mukirasi yekunyunguduka kusanganisa maitiro senge Imwe / Twin screw extruders, jekiseni kuumba uye padivi chikafu. Musanganiswa wemuviri nevirgin polymer pellets unokurudzirwa.
Iyi masterbatch yekugadziriswa kweWPC inogona kutakurwa sekemikari isina njodzi. Inokurudzirwa kuchengetwa munzvimbo yakaoma uye inotonhorera ine tembiricha yekuchengetedza iri pasi pe40 ° C kudzivirira kusangana. Iyo pasuru inofanirwa kuvharwa zvakanaka mushure mekushandisa kwega kwega kudzivirira chigadzirwa kubva pakukanganiswa nehunyoro.
Iyo yakajairwa kurongedza ibhegi rehunyanzvi repepa rine PE yemukati bhegi ine huremu hwemambure e20kg. Mamiriro ekutanga anoramba akamira kwemwedzi makumi maviri nemana kubva pazuva rekugadzira kana akachengetwa mukurudziro yekuchengetedza.
