Pigment dispersion idambudziko rakaoma asi rinowanzo tarisirwa pasi mukugadzira masterbatch. Kupararira kwakashata kunogona kutungamira kune nyaya dzakaita senge kusaenzana kwemavara kugovera, mafirita akavharika, faibha inotsemuka mumafivha akarukwa, uye asina kusimba akasungwa seams. Aya matambudziko haangokanganisa kunaka kwechigadzirwa chete asiwo anowedzera mitengo yekugadzira nekuda kwekushandisa kwepigment kwakanyanya uye kuderera kwemuchina. Pazasi pane gwara rakapfupikiswa rekugadzirisa matambudziko aya nemazvo, zvichibva pamaitiro eindasitiri:
1. Optimize Pigment Selection
Sarudza Inoenderana Pigment: Sarudza pigment inoenderana nepolymer base (semuenzaniso, PE, PP, PET) kuve nechokwadi chekunyorova uye kupararira.
Particle Saizi uye Surface Kurapa: Shandisa pigment nediki diki saizi yekuparadzira zvirinani. Mavara akaiswa pamusoro (semuenzaniso, ane ma dispersants kana machira) anobatsira kuderedza kuungana uye kunatsiridza kuyerera kwezvinhu.
Pigment Loading: Dzivisa kudarika inokurudzirwa pigment mutoro (kazhinji 20-40% ye organic pigments, 50-80% ye inorganic). Kuremedza kunogona kukonzera kusangana uye kusapararira zvakanaka.
2. Wedzera Kusanganiswa uye Kubatanidza
Kusanganiswa Kwepamusoro-Kuveura: Shandisa mapatya-screw extruder kana high-shear mixers kuputsa pigment agglomerates. Gadzirisa screw configuration (semuenzaniso, mabhuroko ekukanya) kukwenenzvera kugera uye kuwedzera kupararira.
Pre-Mixing: Sanganisa pigments ne dispersants kana mutakuri resin usati extrusion kunatsiridza kwekutanga wetting uye kuderedza clumping.
Kudzora Tembiricha: Chengetedza yakanyanya kunyunguduka tembiricha kudzivirira kushatisa pigment kana viscosity nyaya. Kune ma pigment anonzwa kupisa (semuenzaniso, mamwe ma organic pigments), chengetedza tembiricha iri pasi pezvikumbaridzo zvekudzikira.
3. Shandisa Vanoparadzira Agents
Zvinowedzera: Batanidza madhirigi ekuparadzira sewakisi, stearates, kana polymeric dispersants (semuenzaniso, polyethylene wax, EVA-based additives) kuderedza viscosity uye kunatsiridza pigment wetting.
Chiyero: Kazhinji, shandisa 1-5% inopararira nehuremu, zvichienderana nerudzi rwepigment uye kurodha. Kuwedzeredza kunogona kukanganisa mashandiro emagetsi uye kunogona kukonzera kutumbuka (nyaya yekutaridzika kwepamusoro).
Novel Hyperdispersant ye Masterbatch: SILIKE SILIMER Series - Yepamusoro-inoshanda kugadzirisa aids uye anoparadzira vamiririri.
SILIKE SILIMER SeriesKugadzirisa Aids uye Kuparadzira Agentsari anotevera-chizvarwa silicone-based waxes (anonziwo Silicone Hyperdispersants) akagadzirwa kuti ape yepamusoro pigment uye filler kupararira mu masterbatch kugadzirwa. Yakanakira kutarisisa kwemavara, makomisheni akazadzwa, mapurasitiki einjiniya, uye maitiro ekuparadzira anodiwa. Aya ma hyperdispersants anowedzera kugadzikana kwekupisa, rheology, uye mutengo wakanaka uku achibvisa nyaya dzekufambisa dzakajairwa nezvinowedzerwa zvechinyakare (semuenzaniso, wax, amides, esters).
Vhura Superior Pigment Performance neSILIKE SILIMER Series Silicone Hyperdispersants
Kurisa Kubudirira muPigment Concentrates yeZvinhu Zvakasiyana:
→ YePolyolefins: Simudza Yako Pigment Hunhu
• Enhanced Pigment Wetting: Wana mapigment akapfava, anoyevedza ane optimized interaction.
• Kuwedzera Kupararira: Kudzivirira pigment clumping, kuve nechokwadi chemavara akafanana uye kusagadzikana.
• Viscosity Reduction: Gadzirisa kugadzirwa nekuyerera kwakapfava kwekugadzirisa zvirinani.
• Kubuda Kwepamusoro: Wedzera simba rekugadzira pasina kukanganisa unhu.
• Kuwedzera Pigment Concentration: Wana hues dzakapfuma nezvinhu zvishoma, kuderedza mari.
→YeEngineering Plastics uye Polymers: Boost Hunhu uye Kubudirira
• Kubwinya Kwepamusoro kwakavandudzwa: Wana kupedzwa kwepamusoro, kunopenya pazvigadzirwa zvako.
• Zvirinani Mold Release: Iva nechokwadi chekugadzirisa maitiro ekugadzira uye kuderedza kukanganisa.
• Viscosity Reduction: Kuvandudza kushandiswa uye kuderedza kushandiswa kwesimba.
• Higher Production Output: Gadzirisa mutsara wako wekugadzira wepamusoro wepamusoro.
• Yakaderedzwa Pigment Shear: Chengetedza kutendeseka kwepigment kune inobwinya, inogara mavara.
• Superior Dispersion: Wedzera kuenderana kwemavara uye kuita kwezvinhu.
Sei Kusarudza SILIKE's Silicone Hyperdispersants?
• Inodhura-Inoshanda: Kuvandudza kushanda zvakanaka uye kuderedza kutambisa zvinhu.
• Eco-Hushamwari: Wana zvibodzwa zvekusimudzira nemaitiro akakwenenzverwa ekugadzira.
• Versatile Application: Inokodzera huwandu hwakawanda hwemapolymers uye maindasitiri.
4. Rongedza Processing Parameters
Screw Speed: Wedzera screw speed (kazhinji 200-500 rpm) kuwedzera shear uye kupararira. Dzivisa kumhanya zvakanyanya, sezvo izvi zvinogona kutungamirira mukupisa kwekupisa.
Nguva Yekugara: Gadzirisa nguva yekugara muextruder (kazhinji 30-60 masekonzi) kuve nechokwadi chekusanganiswa kwakanyatso pasina kupisa.
Kusefa: Shandisa zvidzitiro mapaketi (semuenzaniso, 100-200 mesh) kubvisa zvisina kupararira zvimedu uye kuve nechokwadi cheuniform masterbatch mhando.
5. Kero Equipment uye Maintenance Matambudziko
Zvishandiso Zvakachena: Gara uchichenesa maextruder, screws, uye kufa kudzivirira kusvibiswa kana kuunganidzwa kwezvinhu zvakasvibiswa zvinokanganisa kupararira.
Pfeka Cheki: Ongorora masiruu nemadhiramu kuti akapfeka here, sezvo midziyo yakasakara inoderedza kugera zvakanaka uye zvichiita kuti isapararire zvakanaka.
Kudyisa Kwazvo: Shandisa magiravimetric feeder epigment chaiyo uye resin dosing, kuve nechokwadi chekuenderana mukupararira kwe pigment.
