Pre-yakapararira Pigment uye Imwe Pigment Concentration

Nekuenderera mberi kwekusimudzira kweindasitiri, mazuva ano epurasitiki kupendesa uye kuumbwa kuri kuenda kune mafambiro emidziyo mikuru, kugadzirwa kwakanyanya otomatiki, kukurumidza-kumhanya, kuenderera mberi kwekunatsiridza uye kumira kwezvigadzirwa. Aya maitiro akakonzera akawanda e-ultra-fine, ultra-thin and Ultra-micro zvigadzirwa, izvo zvinoda mwero wepamusoro wekupararira kwe pigment. Mukuwedzera, zvinodikanwa zvekushanda kwepamusoro, kuchengetedza kwezvakatipoteredza, kuchengetedza simba uye kuderedza mutengo zviri kuwedzerawo. Nekuti iyo yakajairika mapurasitiki ekuumba ekugadzira michina (yakadai se: jekiseni rekugadzira muchina, kutenderera muchina kana imwe screw extruder, nezvimwewo) haigone kupa simba rekugera rinodiwa pakupararira kwepigment panguva yekugadziriswa, basa rekuparadzira pigment rinowanzoitwa nenyanzvi vanogadzira-pigment vatengesi. kana vagadziri vemavara masterbatch.

Pre-dispersed pigment(Inozivikanwawo sePigment Preparation kana SPC-Single Pigment Concentration) imhando yepamusoro yepigment imwechete. Zvinoenderana nehunhu hweakasiyana pigment, iyo yakajairika pre-yakapararira pigment ine 40-60% yepigment yemukati (iyo inoshanda yeiyo pre-yakaparadzirwa pigment inogadzirwa nekambani yedu inogona kusvika 80-90%), uye inogadziriswa neakakosha. gadzira kuburikidza nemidziyo chaiyo. Nzira dzinoshanda dzekuparadzira uye dzakasimba kudzora mhando inoita kuti pigment irimo iratidze yakanakisa particle fomu kuti uwane yakanakisa kuita kwemavara. Kutaridzika kwepigment isati yaparadzirwa inogona kuve yakanaka pow zvimedu zvine saizi ingangoita 0. 2-0.3mm, uye chigadzirwa chinogona zvakare kugadzirwa kuita chidimbu nehukuru hwezvakajairwa.colorbatches. Ndizvo chaizvo nokuti iyo pre-dispersed pigment ine maitiro akajeka akadaro ayo ari kuwedzera kushandiswa mukugadzirwa kwemavara masterbatches.

Thepre-dispersed pigmentine zvinotevera zvakanakira

• Sezvo pigment yakapararira zvachose, ine simba guru remavara. Kuenzaniswa nekushandiswa kweupfu pigments, simba remavara rinogona kuvandudzwa ne5-15%.

• Homogeneous maitiro anongoda kushoma shear kusanganisa masimba kuti awane mhedzisiro inodiwa. Semuenzaniso, mhando yepamusoro masterbatch zvigadzirwa zvinogona kugadzirwa nemidziyo yakapusa (senge screw imwe chete). Adap kune ese marudzi emidziyo yeextrusion, yakagadzikana mhando, inochinjika yekugadzira kuronga.

• Pre-dispersed pigment inoshanda kuti ibudirire kuita kwemavara akakwana: kupenya kwemavara, kujeka, kupenya, nezvimwe.

• Bvisa guruva rinobhururuka mubasa rekugadzira, kuvandudza nzvimbo yekushanda uye kuderedza kusvibiswa.

• Hapana midziyo inosvibisa, inorerutsa kuchenesa midziyo panguva yekushandurwa kwemavara.

• Yakanaka uye yunifomu pigment particles inogona kurebesa hupenyu hwesevhisi yefirita sikirini, kuderedza kutsiva nguva yefirita sikirini uye kunatsiridza kugadzirwa kwakanaka.

• Kuonekwa kwechigadzirwa yunifomu pasina kunamatirana, iyo inokodzera mhando dzakasiyana dzekudyisa; nzira yekufambisa haina kuvharwa kana kuvharwa.

• Inobvisa kudikanwa kwekuparadzira pigments uye zvakanyanya kuwedzera huwandu hweiyo iripo masterbatch zvigadzirwa zvekugadzira.

• Inogona kushandiswa nemamwe mavara, ane simba rinoshandiswa.

• Mafomu akasiyana-siyana emushonga, akakodzera mafomu akasiyana-siyana anotakura resin, maitiro akanaka ekusanganisa.
