Unoziva here musiyano uripowakisi ye polyethyleneuye parafini wakisi mu masterbatch processing?Kana iwe uri mugadziri wemavara masterbatch kana shamwari inofarira ruvara masterbatch, saka tevera tsoka dzeSainuo.Chinyorwa chanhasi chine chokwadi chekukubatsira iwe azvakawanda.

The color masterbatch i pigment concentrate ine resin semutakuri.Iyo resin ine yakakwira melt viscosity uye kusapindirana kwakashata nepamusoro pepigment, saka kunyorova kwakashata, uye zvinonetsa kupinda mumapores e agglomerate kutyora agglomerate;kureva, mu agglomerate Mushure mekuputsika, resin inonyunguduka haigoni kukurumidza kunyorova uye kudzivirira nzvimbo inotangira, uye kudhumhana uye kusangana kune mumwe nemumwe kuchaita kuti zvimedu zvibatane zvakare.Dambudziko iri rinogona kugadziriswa nekuwedzera polyethylene wax.

Mumunda wekugadzira masterbatch, kuwedzera kweparafini wakisi uye polyethylene wakisi kunogona kuvandudza kuyerera kwezvinhu, kunatsiridza kunyorova uye dispersibility ye pigment nezvimwe zvinowedzera, uyezve kunatsiridza mashandiro ekugadzira uye kugona kwekugadzira kune madhigirii akasiyana.Iyo pigment dispersion yakanaka, simba rekupenda re masterbatch rakakwira, kunaka kwemavara kwechigadzirwa kwakanaka, uye chigadzirwa chemavara chakaderera.

Naizvozvo, vagadziri vazhinji vanoshandisa parafini wakisi ine kunyunguduka kweanenge 60 ° C se dispersant kana kuishandisa pamwe chete ne polyethylene wakisi kuwedzera kugadzirwa uye kuderedza mari.Zvino ngatitarisei mutsauko wekuita pakati pezviviri kubva pamaonero ekushandisa kwe masterbatch processing.

1.Physical uye makemikari zvinhu
Parafini wakisi: zita rechirungu Paraffin Wax, chena yakasimba, density 0.87- 0.92g/cm3, kunyungudika 55- 65℃
Polyethylene Wax: Zita reChirungu Polyethylene Wax, white solid, density 0.91-0.95g/cm3, kunyungudika 90-115 ℃

2.Thermal kugadzikana
Iyo yekuzora uye yekuparadzira mumiriri inoshandiswa kune masterbatch inofanirwa kukwanisa kumira tembiricha yekugadzira panguva yekugadzira masterbatch uye kuumbwa kwechigadzirwa chine ruvara.Kana ikanyungudika kana kuora, inova nemhedzisiro yakaipa pane masterbatch kana chigadzirwa chine ruvara.
Iyo tembiricha yekugadzirisa ye masterbatch uye zvigadzirwa kazhinji iri pakati pe160-220 ℃.Mune tembiricha iyi, general polyethylene wax inogona kumira, asi parafini wakisi inonetsa kumira.Isu takaita isothermal kurasikirwa uremu kuyedza pa polyethylene wakisi uye parafini wakisi ine nzvimbo yekunyunguduka ye60 ° C, uye takaona kuti, pasi pe200 ° C, parafini yakarasikirwa ne9.57% yehuremu hwayo mumaminetsi mana, uye mumaminetsi gumi, kurasikirwa nehuremu. yakasvika 20%.Chete kubva pakuona kwekupisa kupisa, polyethylene wakisi inogona kuratidza yakanaka kupisa kusagadzikana, nepo parafini wakisi yakaoma kuvimbisa, saka parafini wakisi haina kukodzera kushandiswa seruvara masterbatch dispersant.

3.Dispersion performance
Kuti uenzanise uye kuyera kupararira kwezvinhu zve polyethylene wax uye parafini wax, black masterbatches akagadzirirwa neakasiyana-siyana ezviviri, zvichiteerana, uye kuyedzwa kwerima kwefirimu kwakaitwa.
Migumisiro yekuedza yakawana kuti mukuwedzera kwechiyero che 0-7%, nekuwedzera kwe polyethylene wax ye black masterbatch, kusviba kwefirimu kwakawedzera zvishoma nezvishoma ne 36.7%, zvichiratidza kuti yakakwirira ye polyethylene wax, zviri nani kuita kwekuparadzira. carbon black.Zvisinei, muchikamu chimwe chete chekuwedzera, nekuwedzera kweparafini, kusviba kweblack masterbatch kwakaderera ne19.9%, zvichiratidza kuti iyo yakakwirira yeparafini, inowedzera kupararira kwekabhoni dema.
Izvi zvinodaro nekuti parafini wakisi wakanyorova kabhoni dema zviri nyore kupfuura polyethylene wax, asi panguva imwechete inoderedza zvakanyanya viscosity yehurongwa.Kunyanya kuderera viscosity kunoderedza zvakanyanya kutapurirana kweshear simba, uye kupararira kunovhiringidzika.Basa rekubatana kwe agglomeration.Nokudaro, kuenzanisa kwemigumisiro yekuedza kunoratidza kuti polyethylene wakisi ine mafuta akanaka ekuzora uye kuparadzira pa carbon black, nepo muvara masterbatch, carbon black yakawedzerwa neparafini wakisi ichave yakanyanya kuipa.

Qingdao Sainuo Chemical Co., Ltd.Isu tiri vagadziri vePE wax, PP wax, OPE wax, EVA wax, PEMA, EBS, Zinc/Calcium Stearate….Zvigadzirwa zvedu zvakapfuura REACH, ROHS, PAHS, FDA yekuongorora.

Sainuo zorora wakavimbiswa wakisi, gamuchira kubvunza kwako!
