Polyethylene seraamagwiritsidwa ntchito kwambiri.Itha kumwaza ma pigment ndi ma fillers mu masterbatch amtundu, kupereka mafuta oyenera muzosakaniza za PVC, kupereka mapulasitiki aukadaulo, ndikupereka mawonekedwe ofananira pakudzaza kapena kulimbikitsa zida zosinthidwa.

1. Kugwiritsa ntchitopa waxmu Colour Masterbatch
Sera ya polyethylene imagwirizana bwino ndi tona, ndiyosavuta kunyowetsa pigment, ndipo imatha kulowa mkati mwa pores mkati mwa pigment aggregate kuti ifooketse mgwirizano, kuti mtundu wa pigment ukhale wosavuta kusweka ndi mphamvu yakumeta ubweya wakunja, kumene kwaiye particles angathenso mwamsanga wetted ndi kutetezedwa.Chifukwa chake, itha kugwiritsidwa ntchito ngati dispersant ndi kudzaza masterbatch yamitundu yosiyanasiyana ya thermoplastic resin colorbatch, ndi dispersant yothira ya masterbatch owonongeka.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 magwiridwe antchito ndi zokolola komanso kukhazikika kwa kubalalitsidwa.
2. Kugwiritsa ntchito sera ya polyethylene muzinthu za PVC

PVC imadziwika bwino kuti polyvinyl chloride.Kutentha kwake kothamanga kwa viscous kuli pafupi kwambiri ndi kutentha kwachiwonongeko, choncho n'kosavuta kusokoneza m'njira zosiyanasiyana panthawi yokonza, kotero idzataya ntchito yake.Choncho, kutentha stabilizer ndi lubricant ayenera kuwonjezeredwa chilinganizo cha PVC osakaniza zosakaniza.Yoyamba imapangitsa kukhazikika kwake kwamafuta, ndipo yotsirizirayi imachepetsa kukangana pakati pa unyolo wa ma cell a PVC ndi mphamvu yochotsa filimu pakati pa PVC kusungunuka ndi chitsulo, kuti apititse patsogolo kusinthika kwa PVC kukhala zinthu zosiyanasiyana.Polyethylene sera ndiwothiridwa ndi polyethylene serandi mafuta omwe amapezeka mu PVC.
Pokonza PVC, palibe kusungunuka koyera, tinthu tating'onoting'ono (100 μ M, topangidwa ndi tinthu tating'onoting'ono tating'onoting'ono) ndikugawanika kukhala mipira yaying'ono (1) pansi pa kumeta ubweya wamafuta ndi makina μ Njira ya spherule. kugawanika kukhala 100nm (m) nthawi zambiri amatchedwa gelation kapena plasticization.Kuti mukwaniritse bwino zamakina, pamwamba ndi kusinthika, digiri ya gelation ndi yoyenera pakati pa 70% ~ 85%.Sera yabwino ya polyethylene imatha kuchedwetsa kapena kufulumizitsa njira ya gelation.Pambuyo pa kusungunuka, sera ya homopolyethylene ilipo pakati pa tinthu tating'onoting'ono kapena tinatake tozungulira, kuchepetsa kukangana pakati pa tinthu tating'onoting'ono tomwe timayambira kapena tinatake tozungulira, kuti tichepetse kukangana kwa kutentha kwa kusungunula, kuchedwetsa pulasitiki ya PVC, ndikuwongolera kukhazikika kwamafuta a PVC.Sera yokhala ndi okosijeni ya polyethylene imakhala yogwirizana ndi PVC, yomwe imatha kumamatira pamwamba pa TB, kuonjezera kukhuthala kwa kusungunuka, ndikukhala ndi kusintha kwabwino pa khalidwe la gelation.Ntchito yake ina yaikulu ndi kupanga filimu pa PVC kusungunuka ndi zitsulo pamwamba kuchepetsa mikangano pakati pa kusungunula ndi processing zida.Ndiwothandizira bwino kutulutsa PVC processing.Makamaka mandala PVC (organotin stabilizer) filimu, kuwonjezera mlingo woyenera wa oxidized polyethylene sera sangakhale ndi ntchito yabwino kumasulidwa, komanso sikungachepetse kuwonekera.
Pakalipano, kuwonjezera pa kupanga polyethylene sera ndi oxidized polyethylene sera, parafini, Fischer Tropsch sera ndi mankhwala ndi mankhwala amagwiritsidwanso ntchito kwambiri mu PVC.Ayeneranso kufananizidwa mosinthika malinga ndi ma terminal application.Mwachitsanzo, otsika kusungunuka mfundo parafini akhoza kuchita mbali ya kondomu oyambirira, sing'anga kusungunuka mfundo polyethylene sera ndi Fischer Tropsch sera akhoza kuchita mbali ya sing'anga-akuti kondomu, ndi mkulu kusungunuka mfundo oxidized polyethylene sera akhoza kuchita mbali ya kondomu kenako.Mafuta ena omwe ali ndi kukana kutentha pang'ono, monga sera ya parafini ndi mafuta acid ester, ndi osavuta kuyika pakufa kwa zinthu zomwe zatulutsidwa ndi mpukutu wozizira wa filimu ya calendered.Zinthu izi zitha kukhala ndi zotsatira zoyipa pamapangidwe azinthu zomaliza, komanso malo ogwirira ntchito komanso kupanga kwa ogwira ntchito pamalowo.Kuphatikiza apo, kuphatikiza kwamafuta amodzi mu PVC ndikokwera kwambiri.Ngati phukusi lamafuta ophatikizika limagwiritsidwa ntchito, zigawo zosiyanasiyana sizigwirizana ndipo zimayenderana, zomwe zimakhalanso zosavuta kutsogolera kuwunika kokakamiza.Chifukwa chake, molingana ndi kagwiritsidwe ntchito ka zinthu, monga ngati kusindikiza ndi kupopera mbewu mankhwalawa ndikofunikira, ndikofunikira kwambiri kusankha mafuta omwe ali ndi mtundu wokhazikika komanso kukana kutentha kwabwino kuti apange bwino komanso kuwongolera zinthu.

3. Kugwiritsa ntchito sera ya polyethylene mu mapulasitiki a engineering
Mafuta odzola amafunikanso kuwonjezeredwa ku mapulasitiki a engineering omwe amagwiritsidwa ntchito nthawi zambiri PA6, PA66, pet, PBT ndi PC kuti athetse ndikuwongolera mphamvu yakuyenda kapena kugwirizanitsa.Panthawiyi, tikasankha sera ya polyethylene, sitingathe kusankha sera ya homopoly polyethylene, chifukwa molingana ndi mfundo yofanana ndi yogwirizana, mapulasitiki a engineeringwa ali ndi polarity yamphamvu kapena yofooka.Tiyenera kusankha polyethylene sera ndi polarity ena, mwachitsanzo, oxidized polyethylene sera, ethylene acrylic asidi copolymer sera, maleic anhydride kumtengowo polyethylene sera, etc. pa maziko awa, ife zina zenera malinga ndi ntchito zosowa.Mwachitsanzo, mu PA6, ngati kuli kofunikira kupititsa patsogolo kudzaza kwa jekeseni, kumafunika mafuta amkati, omwe amatha kusintha kwambiri madzi a zinthuzo, ndikuphatikizana ndi chinthu china chomasulidwa, monga ethylene acrylic. asidi copolymer sera, ntchito imeneyi akhoza anazindikira.
Ngati mukufuna kusintha pamwamba katundu PC mankhwala, muyenera lubricant kunja, monga oxidized polyethylene sera, amene akhoza kusintha demoulding katundu wa mankhwala pa akamaumba jekeseni.Ngati mukufuna kuthetsa vuto la CHIKWANGWANI choyandama padziko mu galasi CHIKWANGWANI analimbitsa PA66 zakuthupi, mukhoza kukwaniritsa zimenezi powonjezera maleic anhydride kumtengowo polyethylene, chifukwa – Oh kuyanjana pakati maleic anhydride ndi pamwamba pa galasi CHIKWANGWANI ndi zabwino kwambiri. , zomwe zimatha kukulitsa kulumikizana pakati pa magalasi ulusi ndi PA66.
Inde, posankha mitundu yosiyanasiyana ya sera ya polyethylene, tiyenera kuganiziranso za kukana kutentha, particle morphology ndi zina zotero.
Malingaliro a kampani Qingdao Sainuo Chemical Co.,Ltd.Ndife opanga sera PE, PP sera, OPE sera, EVA sera, PEMA, EBS, Zinc / Calcium Stearate….Zogulitsa zathu zadutsa REACH, ROHS, PAHS, FDA kuyesa.
