Makonda a polyethylene sera sera ndi mtundu watsopano wa sera yapamwamba kwambiri ya polar. Chifukwa machulukidwe a molekyulu a sera ya oxidized polyethylene amakhala ndi kuchuluka kwamagulu a carbonyl ndi methyl, kugwirizana kwake ndi zodzaza, phala lamitundu ndi utomoni wa polar kwasintha kwambiri. Mafuta ndi dispersibility a polar kasamalidwe dongosolo bwino kuposa wa polyethylene sera. Pa nthawi yomweyi, kugwirizana kogwirizana kumaganiziridwanso. Kachitidwe kake ndikufanana ndi Honeywell ac sera.

Sainuo mkulu kachulukidwe sera , akhoza kulimbikitsa plasticization, ndipo ali wabwino pambuyo matenthedwe bata, akhoza kupereka mankhwala plasticization wabwino ndi luster, yaitali mosalekeza kupanga mkombero, mu masterbatch adzawonjezera kubalalitsidwa ndi kuwala, koma ali ndi zotsatira. pa nthawi ya oxidative induction.

Khalidwe:
Sera ya oxidized polyethylene, yomwe imadziwikanso kuti ope wax, ili ndi zinthu zapadera monga kukhuthala kochepa, kufewetsa kwambiri komanso mphamvu zabwino. Ilibe kawopsedwe, kukana kutentha kwabwino, zinthu zotsika kwambiri pakutentha kwambiri komanso dispersibility yabwino kwa filler ndi phala lamtundu. Izo osati zabwino kwambiri wettability kunja, komanso ali ndi kondomu amphamvu mkati, komanso ali kugwirizana anachita tingati kusintha zokolola za pulasitiki granulation ndi kuchepetsa mtengo mankhwala. Imayenderana kwambiri ndi utomoni wa rabara wa isoprene, kukana bwino kwa chinyezi kutentha kwachipinda, kukana kwamphamvu kwamankhwala, kuchita bwino kwamagetsi, ndipo kumatha kusintha mawonekedwe azinthu zomalizidwa.
Njira yopangira:
Amapangidwa ndi okosijeni wa sera ya polyethylene kudzera munjira yapadera ya okosijeni.

Ntchito yayikulu:

1. M'munda wa granulation ya pulasitiki, imakhala ndi mphamvu yokwanira yothira mkati ndi kunja kwa zinthu za PVC. Pamene oxidized polyethylene sera anawonjezedwa mu chilinganizo okhwima PVC mankhwala, wettability ake ndi bwino kuposa mafuta ena. Amagwiritsidwa ntchito Pe, PVC zingwe, PVC mbiri, PVC chitoliro zovekera, ndi mtundu watsopano wa lubricant apamwamba pulasitiki granulation.
2. Thickener, lubricant, polishing fluid ndi silane coupling agent yomwe imagwiritsidwa ntchito ngati thickener kapena filler ya concentrated pulasitiki masterbatch, polypropylene nsalu masterbatch, additive masterbatch ndi filling masterbatch.
3. Amagwiritsidwa ntchito ngati mafuta, chochotsera filimu ndi zosungunulira organic popanga ndi kukonza mphira ndi zinthu zapulasitiki. Chifukwa cha kusungunuka kwake kwakukulu komanso kukhuthala kwakukulu, imatha kulimbikitsa kusungunuka kwa utomoni, kuchepetsa mphamvu yogwiritsira ntchito kusakaniza kwa utomoni, kuchepetsa kumamatira pakati pa utomoni ndi chipolopolo cha nkhungu, kuthandizira kuchotsa filimu, ndikugwira ntchito yopaka mkati ndi kunja. Pa nthawi yomweyi, ilinso ndi katundu wabwino wa antistatic.
4. Amagwiritsidwa ntchito ngati thickener ndi anti scratch wothandizira wa inki yosindikiza.
5. Monga mamasukidwe akayendedwe owongolera otentha Sungunulani zomatira.
6. Itha kugwiritsidwa ntchito ngati chithandizo chothandizira filimu ya Aluminium platinamu.
Pali magulu zinchito mu maselo dongosolo unyolo wa oxidized polyethylene sera, kotero miscibility ake ndi utomoni polar mwachionekere bwino, amene ali bwino kuposa polyethylene sera.

Mu dongosolo la PVC, Sainuo low kachulukidwe polyethylene yokhala akhoza pulasitiki pasadakhale, ndipo makokedwe kenako kuchepetsedwa. Ili ndi mafuta abwino kwambiri amkati ndi kunja. Itha kupititsa patsogolo kuchulukana kwa utoto, kupangitsa kuti zinthu ziziwoneka bwino komanso zimathandizira kupanga bwino.
Kusiyanitsa pakati pa sera ya polyethylene ( sera ya PE ) ndi sera ya polyethylene oxidized
1. Kupanga ndi kosiyana
Njira zambiri zopangira sera ya polyethylene zimaphatikizapo kuthamanga kwambiri komanso kusinthasintha kwapansi. Sera yomwe imachokera ku kuthamanga kwambiri imakhala ndi ma carbon bonds ndipo imakhala ndi malo otsika osungunuka. Pamene sera analandira otsika kuthamanga ndi zovuta, koma ndi osauka lubricity. Sera ya oxidized polyethylene imapezeka kuchokera ku sera ya polyethylene pambuyo pa okosijeni.
2. Kusiyana kwa magwiridwe antchito
(1) Sera ya polyethylene ( sera ya PE ) , yomwe imadziwikanso kuti sera ya polima. Chifukwa cha kukana kwambiri kuzizira, kukana kutentha, kukana kwa asidi ndi kukana kuvala, wakhala akugwiritsidwa ntchito kwambiri. Pakupanga ndi kupanga kwabwinobwino, gawo ili la sera ngati chowonjezera litha kuwonjezeredwa mwachindunji pakupanga ndi kukonza mphira wa isoprene, womwe ukhoza kuwongolera gloss ya zinthu ndi magwiridwe antchito akupanga ndi kukonza. Monga lubricant, imakhala ndi zinthu zokhazikika komanso zamagetsi zamagetsi.
(2) Mamolekyu amtundu wa sera ya oxidized polyethylene imakhala ndi gulu la carbonyl ndi gulu la methyl. Sera ya oxidized polyethylene ndi mtundu watsopano wa sera wapamwamba kwambiri wa polar. Chifukwa chake, kugwirizana kwake ndi zodzaza, phala lamtundu ndi utomoni wa polar zasinthidwa kwambiri, ndipo kunyowa kwake ndi kufalikira kwake kuli bwino kuposa sera za polyethylene. Panthawi imodzimodziyo, imaganiziranso kugwirizanitsa reactivity.
Qingdao Sainuo Chemical Co., Ltd. Ndife opanga sera ya PE, sera ya PP, sera ya OPE, sera ya EVA, PEMA, EBS, Zinc / Calcium Stearate …. Zogulitsa zathu zadutsa kuyesa kwa REACH, ROHS, PAHS, FDA.
Sainuo chidaliro sera, kulandira atafunsira anu!
