Zofunikira pakupangira mtundu wa masterbatch ndizovuta kwambiri, ndipo njira yonyowa imagwiritsidwa ntchito nthawi zambiri.Mtundu wa masterbatch ndi nthaka ndi gawo-lotembenuzidwa ndi madzi, ndipo mayesero angapo ayenera kuchitidwa pamene pigment ikugwedezeka, monga kutsimikiza kwa fineness, diffusion performance, solid content and color paste fineness of sanding slurry.
Pali njira zinayi zopangira zonyowa za mtundu wa masterbatch: njira yochapira, njira yokanda, sopo wachitsulo, ndi inki.
(1) Njira yotsuka: Pigment, madzi ndi dispersant amapangidwa ndi mchenga kuti pigment ikhale yaying'ono kuposa 1pm, ndipo pigment imasamutsidwa mu gawo la mafuta ndi njira yosinthira gawo, kenako zowuma kuti zipeze mtundu wa masterbatch.Zosungunulira za organic ndi zida zofananira zosungunulira zosungunulira zimafunikira pakusinthika kwa gawo.Ndondomekoyi ili motere:
Pigment, dispersant, wowonjezera kuchuluka - mpira mphero - homogenization ndi kukhazikika mankhwala - kuyanika - utomoni kusakaniza - extrusion granulation mtundu masterbatch
(2) Njira yokandira Njira yokandirayo ili motere:
Pigment, zothandizira, kukankha utomoni - kutaya madzi m'thupi - kuyanika - kusakaniza utomoni - extrusion granulation mu masterbatch
(3) Njira yachitsulo ya sopo ya pigment imadulidwa mpaka kukula kwa 1um, ndipo yankho la sopo limawonjezedwa pa kutentha kwina kuti gawo la pigment particles likhale lonyowetsedwa mofanana ndi yankho la sopo kuti likhale ndi yankho la saponification. .Onjezerani mchere wachitsulo ndi pamwamba pa pigment.The saponification wosanjikiza mankhwala amachitira kupanga zoteteza wosanjikiza wa zitsulo sopo (magnesium stearate), kuti finely pansi pigment particles si flocculate.
Njira yoyendetsera sopo yachitsulo ndi motere:
Pigment, zothandizira, kusakaniza madzi - kulekanitsa ndi kutaya madzi m'thupi - kuyanika - kusakaniza utomoni - extrusion granulation mu masterbatch
(4) Njira ya inki Popanga mtundu wa masterbatch, njira yopangira phala la inki imagwiritsidwa ntchito, ndiko kuti, kudzera mukupera kwa mipukutu itatu, wosanjikiza wocheperako wama cell umakutidwa pamwamba pa pigment.Phala lophwanyidwa bwino limasakanizidwa ndi utomoni wonyamulira, kenaka amapangidwa ndi pulasitiki ndi mphero yamapasa, ndipo pamapeto pake amapangidwa ndi screw-screw kapena twin-screw extruder.
Njira yoyendera ili motere:
Pigment, zowonjezera, dispersants, utomoni, zosungunulira zosungunulira - mipukutu itatu mphero mtundu phala - desolventizing - utomoni kusakaniza - extrusion granulation mu masterbatch.
Njira yotuluka pakuwuma kwa mtundu wa masterbatch: pigment (kapena utoto) wothandizira, dispersant, chonyamulira - kusakaniza kothamanga kwambiri, kugwedeza ndi kumeta ubweya - mapasa-screw extrusion granulation - kudula kozizira ndi granulation mu mtundu masterbatch
