polyethylene sera ndi yotsika kwambiri yamamolekyulu (<1000) polyethylene, yomwe ndi yothandiza kwambiri pamakampani opanga mapulasitiki. Kugwiritsa ntchito sera ya polyethylene mu pulasitiki extrusion kumatha kupititsa patsogolo kutulutsa kwazinthu, kukulitsa kupanga, ndikulola ndende yodzaza kwambiri.
Sera ya polyethylene imagwiritsidwa ntchito kwambiri pokonza mtundu wa masterbatch. Cholinga chowonjezera sera ya polyethylene sikungosintha magwiridwe antchito amtundu wa masterbatch, komanso kulimbikitsa kubalalitsidwa kwa inki mumtundu wa masterbatch. Kubala kwa pigment ndikofunikira kwambiri kwa mtundu wa masterbatch. Ubwino wa Colour Masterbatch makamaka umadalira kupezeka kwa pigment. Kubalalika kwa pigment kwabwino, mphamvu yopaka utoto kwambiri ya Colour Masterbatch, mitundu yabwino yazinthu komanso mtengo wotsika. Sera ya polyethylene imatha kusintha kuchuluka kwa mtundu wa pigment kumlingo wina. Ndi dispersant wamba pakupanga mtundu masterbatch.
Chifukwa cha njira zosiyanasiyana zopangira, sera ya polyethylene imatha kugawidwa m'mitundu iwiri: mtundu wa polymerization ndi mtundu wosweka. Yoyamba ndi yopangidwa ndi polyethylene polymerization yothamanga kwambiri, ndipo yotsirizirayi imapangidwa ndi kuphulika kwamafuta a polyethylene. Chifukwa cha mawonekedwe osiyanasiyana a maselo, sera ya polyethylene imatha kugawidwa m'mitundu iwiri: kachulukidwe kakang'ono komanso kocheperako, komwe kamafanana ndi polyethylene. Chifukwa cha kusiyana kwa njira zopangira, kachulukidwe, kulemera kwa maselo, kugawa kwa mamolekyulu ndi kapangidwe ka maselo, mawonekedwe a pe peyi mu mtundu masterbatch amasiyananso.

wopanga pe seraili ndi kulemera kwakukulu kwa maselo, kukhuthala kwakukulu, Mafuta onse ndi kubalalitsidwa; kachitidwe ka kubalalikana ndi kofanana ndi sera ya BASF A ndi Honeywell AC6A.
Dispersion mechanism ya polyethylene sera pigment in Colour Masterbatch
Colour masterbatch ndi pigment yokhazikika yokhala ndi utomoni ngati chonyamulira. Pigment ilipo m'magawo atatu: choyambirira, condensate ndi aggregate. The kupezeka limagwirira wa pigment ndi ndondomeko kuswa polima particles mu agglomerates ndi chachikulu particles, ndi kukhazikika ndi kumene kwaiye particles. Kubalalika kwa pigment mu utomoni kungasonyezedwe m'masitepe atatu: choyamba, utomoni umasungunuka umanyowetsa pamwamba pa pigment aggregate ndikulowa mkati mwa pores; Kachiwiri, aggregates ndi wosweka pansi zochita za kunja kukameta ubweya mphamvu ndi mmene kugundana pigment particles; Pomaliza, ndi kumene kwaiye particles ndi wetted ndi TACHIMATA ndi utomoni Sungunulani, amene ali khola ndipo salinso agglomerated.
Kusungunuka kwa utomoni kumakhala ndi kukhuthala kwakukulu komanso kusagwirizana bwino ndi mtundu wa pigment, kotero sikunyowetsa bwino ndipo kumakhala kovuta kulowa mu ma pores a aggregate. Choncho, sangathe kusamutsa kukameta ubweya mphamvu ndi zovuta kuwononga akaphatikiza. Pamene masterbatch dongosolo ndi polyethylene sera ndi kukonzedwa, polyethylene sera amasungunuka pamaso utomoni ndi wokutidwa pa pigment pamwamba. Chifukwa otsika mamasukidwe akayendedwe ake komanso ngakhale wabwino ndi inki, polyethylene sera n'zosavuta kunyowa inki, kulowa mkati pores mkati pigment aggregates, kufooketsa mgwirizano, kupanga aggregates mosavuta kutsegula pansi pa zochita za kunja kukameta ubweya mphamvu, ndi particles watsopano akhoza kukhala. mwachangu chonyowa ndikutetezedwa. Komanso, polyethylene sera akhoza kuchepetsa mamasukidwe akayendedwe a dongosolo ndi kusintha fluidity. Chifukwa chake, kuwonjezera sera ya polyethylene popanga mtundu wa masterbatch kumatha kupititsa patsogolo kaphatikizidwe kake, kukulitsa zotulutsa, ndikuloleza kuchuluka kwa pigment.

Kuwonjezera polyethylene sera kwa mtundu masterbatch kumalimbitsa wetting ndi malowedwe a mpweya wakuda aggregates, amachepetsa tinthu kukula mwa kukameta ubweya mphamvu, bwino ngakhale pakati pa dongosolo ndi mpweya wakuda, ndi abwino kubalalitsidwa; Pa nthawi yomweyo, kuchepetsa mamasukidwe akayendedwe a dongosolo sizingangowonjezera zokolola, komanso kuchepetsa kwambiri kukameta ubweya wa mphamvu kufalikira ku carbon black aggregate, yomwe si yabwino kwa kubalalitsidwa. Kupikisana pakati pa zotsatira ziwiri zosiyana kumabweretsa kukhalapo kwa mlingo woyenera wa mlingo. Sera ikawonjezeredwa ku dongosolo, kubalalitsidwa kwake kwabwino kumakhala kokulirapo kuposa kulepheretsa kubalalitsidwa, ndipo kumawonetsa kufalikira kwabwinoko. Ndi kuwonjezeka kwa mlingo wa sera, zotsatira ziwirizo zimalimbikitsidwa. Pamene sera ndende kuposa enieni mtengo, zake chokhwima ndi kubalalitsidwa zotsatira amapambana. Panthawi imeneyi, zimazindikira kuti kupezeka kwamtundu kumachepa.
(1) Limbikitsani kubalalikana ndi mphamvu zopaka utoto. Chifukwa cha kulemera koyenera kwa molekyulu ya sera ya polyethylene, kukhuthala kwake kumapangitsa kuti pigment ikhale yabwino kubalalitsidwa pansi pa mphamvu yakumeta ubweya. Chifukwa chake, ndi mtundu womwewo wa pigment, pali kusiyana kwakukulu pakupaka utoto pakati pa waxy masterbatch ndi masterbatch opanda sera.
(2) Kupititsa patsogolo ntchito ndi zokolola. Chifukwa otsika maselo kulemera kwa polyethylene sera ndi mamasukidwe akayendedwe ake ndi otsika kwambiri kuposa utomoni chonyamulira, mamasukidwe akayendedwe a master mtanda kusungunuka akhoza kwambiri kuchepetsedwa.
