Kodi mukudziwa kusiyana pakatiphula la polyethylenendi paraffin sera mu masterbatch processing?Ngati ndinu wopanga mtundu masterbatch kapena mnzanu yemwe ali ndi chidwi ndi mtundu wa masterbatch, tsatirani mapazi aSainuo.Lero nkhani ndi wotsimikiza kupindula inu azambiri.

Mtundu masterbatch ndi pigment yokhazikika ndi utomoni monga chonyamulira.The utomoni ali mkulu kusungunuka mamasukidwe akayendedwe ndi osauka ngakhale pamwamba pa pigment, kotero kunyowetsa ndi osauka, ndipo n'zovuta kulowa mu pores wa agglomerate kuswa agglomerate;ndiko kuti, mu agglomerate Pambuyo wosweka, utomoni kusungunula sangathe mwamsanga kunyowa ndi kuteteza nascent pamwamba, ndi kugundana ndi kukhudzana wina ndi mzake zidzachititsa particles kachiwiri aggregate.Vutoli litha kuthetsedwa powonjezera sera ya polyethylene.

M'munda wa masterbatch kupanga, Kuwonjezera paraffin sera ndi polyethylene sera akhoza kusintha fluidity wa zipangizo, kusintha wettability ndi dispersibility wa inki ndi zina zina, ndiyeno kusintha processing ntchito ndi dzuwa kupanga kwa madigiri osiyanasiyana.Kubalalika kwa pigment ndikwabwino, mphamvu yopaka utoto ya masterbatch ndi yayikulu, mtundu wamtundu wazinthuzo ndi wabwino, ndipo utoto wa utoto ndiwotsika.

Choncho, opanga ambiri amagwiritsa ntchito sera ya parafini ndi malo osungunuka a 60 ° C ngati dispersant kapena ntchito pamodzi ndi polyethylene sera kuonjezera kupanga ndi kuchepetsa ndalama.Tsopano tiyeni tiwone kusiyana kwa magwiridwe antchito pakati pa ziwirizi kuchokera pamalingaliro ogwiritsira ntchito masterbatch processing.

1.Physical ndi mankhwala katundu
Sera ya parafini: Dzina lachingerezi Paraffin Wax, yoyera yolimba, kachulukidwe 0.87- 0.92g/cm3, malo osungunuka 55- 65 ℃
Sera ya Polyethylene: Dzina lachingerezi Polyethylene Sera, yoyera yolimba, kachulukidwe 0.91-0.95g/cm3, malo osungunuka 90-115 ℃

2.Kukhazikika kwa kutentha
Mafuta opangira mafuta ndi obalalitsa omwe amagwiritsidwa ntchito pa masterbatch ayenera kupirira kutentha popanga masterbatch ndi kupanga zinthu zamitundu.Ngati vaporizes kapena kuwola, zimakhala ndi zotsatira zoyipa pa masterbatch kapena mankhwala achikuda.
The processing kutentha kwa masterbatch ndi mankhwala zambiri pakati 160-220 ℃.Pa kutentha kumeneku, sera ya polyethylene imatha kupirira, koma sera ya parafini ndi yovuta kupirira.Tidayesa kuwonda kwa isothermal pa sera ya polyethylene ndi sera ya parafini yokhala ndi malo osungunuka a 60 ° C, ndipo tidapeza kuti, pansi pa 200 ° C, parafini idataya 9.57% ya kulemera kwake mu mphindi 4, ndipo mu mphindi 10, kuchepa thupi. kufika 20%.Pokhapokha pakuwona kukana kutentha, sera ya polyethylene imatha kuwonetsa kukana bwino kwa kutentha, pomwe sera ya parafini imakhala yovuta kutsimikizira, kotero sera ya parafini si yoyenera kugwiritsidwa ntchito ngati mtundu wa masterbatch dispersant.

3.Kubalalika kwantchito
Pofuna kufananitsa ndi kuyeza kupezeka kwa sera ya polyethylene ndi sera ya parafini, ma masterbatches akuda adakonzedwa ndi magawo osiyanasiyana a awiriwa, motero, ndipo kuyesa kwakuda kwa filimuyi kunachitika.
The experimental zotsatira anapeza kuti kuwonjezera chiŵerengero cha 0-7%, ndi kuwonjezeka polyethylene sera zili wakuda masterbatch, filimu wakuda chinawonjezeka pang'onopang'ono ndi 36.7%, kusonyeza kuti apamwamba phula polyethylene zili, ndi bwino kubalalitsidwa ntchito. mpweya wakuda.Komabe, mu chiŵerengero chomwecho chowonjezera, ndi kuwonjezeka kwa parafini, mdima wa black masterbatch unatsika ndi 19.9%, zomwe zimasonyeza kuti parafini imakhala yokwera kwambiri, kufalikira kwa carbon black kumakhala koyipitsitsa.
Izi zili choncho chifukwa parafini wax yonyowa mpweya wakuda mosavuta kuposa polyethylene sera, koma nthawi yomweyo kwambiri kuchepetsa mamasukidwe akayendedwe a dongosolo.Kutsika kwambiri mamasukidwe akayendedwe amafooketsa kwambiri kufala kwa kukameta ubweya mphamvu, ndipo kubalalitsidwa kumasokonekera.Udindo wa mgwirizano wa agglomeration.Choncho, kuyerekezera zotsatira zoyesera zimasonyeza kuti sera ya polyethylene imakhala ndi mafuta abwino komanso obalalitsa pa carbon wakuda, pamene mumtundu wa masterbatch, mpweya wakuda wowonjezera ndi sera ya parafini udzakhala woipa kwambiri.

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.

Sainuo khalani otsimikiza sera, landirani kufunsa kwanu!
