Phatlalatso ea pigment ke phephetso e mahlonoko empa hangata e sa lekanyetsoe tlhahisong ea masterbatch. Phatlalatso e mpe e ka baka mathata a kang kabo ea mebala e sa leka-lekaneng, lifilthara tse koetsoeng, likhaello tsa likhoele ka har'a likhoele tse ohiloeng, le likhoele tse fokolang tse cheselitsoeng. Mathata ana ha a ame boleng ba sehlahisoa feela empa hape a eketsa litšenyehelo tsa tlhahiso ka lebaka la tšebeliso e phahameng ea pigment le nako ea ho theoha ha mochini. Ka tlase ke tataiso e khuts'oane ea ho sebetsana le liphephetso tsena ka katleho, ho ipapisitsoe le mekhoa ea indasteri:

1. Ntlafatsa Khetho ea Pigment
Khetha li-pigments tse lumellanang: Khetha li-pigments tse lumellanang le polymer base (mohlala, PE, PP, PET) ho netefatsa ho koloba le ho hasana hantle.

Boholo ba Particle le Phekolo ea Bokaholimo: Sebelisa li-pigments tse nang le boholo bo nyane bakeng sa phallo e ntle. Li-pigments tse entsoeng ka holim'a metsi (mohlala, ka li-dispersants kapa li-coatings) li thusa ho fokotsa ho kopana le ho ntlafatsa thepa ea phallo.

Pigment Loading: Qoba ho feta boima ba 'mala o khothaletsoang (ka tloaelo 20-40% bakeng sa mebala ea tlhaho, 50-80% bakeng sa inorganic). Ho jara ho feta tekano ho ka baka agglomeration le ho hasana hampe.

2. Ntlafatsa Ho Kopanya le ho Kopanya
High-Shear Mixing: Sebelisa li-extruder tse peli-screw kapa li-mixer tsa ho kuta haholo ho senya li-piglomerates. Fetola tlhophiso ea screw (mohlala, li-blocks) ho ntlafatsa sekiri le ho ntlafatsa phallo.

Pre-Mixing: Kopanya li-pigments le li-disperants kapa li-carrier resin pele ho extrusion ho ntlafatsa ho koloba ha pele le ho fokotsa ho bokellana.

Taolo ea Mocheso: Boloka mocheso o nepahetseng oa ho qhibiliha ho qoba ho senyeha ha 'mala kapa mathata a viscosity. Bakeng sa mebala e sa utloeng mocheso (mohlala, mebala e itseng ea tlhaho), boloka mocheso o le ka tlase ho menyako ea ho senyeha ha eona.

3. Sebelisa Liemeli Tse Hlahisang
Li-additives: Kenyelletsa lisebelisoa tse qhalakang tse kang boka, li-stearate, kapa li-polymeric dispersants (mohlala, boka ba polyethylene, li-additives tse thehiloeng ho EVA) ho fokotsa viscosity le ho ntlafatsa pigment wetting.
Tekanyetso: Ka tloaelo, sebelisa 1-5% dispersant ka boima ba 'mele, ho itšetlehile ka mofuta oa pigment le ho laela. Tšebeliso e feteletseng e ka ama thepa ea mochine hampe 'me e ka baka palesa (taba ea ponahalo ea bokaholimo).
Novel Hyperdispersant bakeng sa Masterbatch: SILIKE SILIMER Series - Lisebelisoa tse sebetsang hantle tse sebetsang hantle le li-agent tsa ho qhalakanya.

SILIKE SILIMER SeriesLithuso tsa ho sebetsa le li-Agent tse hasanyangKe li-wax tse thehiloeng ho silicone tsa moloko o latelang (hape li bitsoa Silicone Hyperdispersants) tse etselitsoeng ho fana ka pigment e phahameng le ho hasana ha li-filler tlhahiso ea masterbatch. E loketse li-concentrate tsa mebala, metsoako e tlatsitsoeng, lipolasetiki tsa boenjineri, le lits'ebetso tse hlokang ho hasana. Li-hyperdispersants tsena li matlafatsa botsitso ba mocheso, rheology, le katleho ea litšenyehelo ha li ntse li felisa litaba tsa ho falla tse tloaelehileng le li-additives tsa setso (mohlala, boka, li-amides, ester).

Notlolla Ts'ebetso e Phahameng ea Pigment ka SILIKE SILIMER Series Silicone Hyperdispersants

Eketsa Katleho e Ntle ho Pigment Concentrate Bakeng sa Mefuta e sa tšoaneng ea Lisebelisoa:

→ Bakeng sa Polyolefin: Phahamisa Boleng ba Pigment ea Hau
• Ho Metsisa Pigment e Matlafalitsoeng: Fumana li-pigment tse boreleli, tse hlasimollang ka ho sebelisana hantle.

• Phahamiso e Ntlafetseng: Thibela ho bokellana ha pigment, ho etsa bonnete ba hore 'mala o ts'oanang le ho tsitsisa.

• Phokotso ea Viscosity: Ho tsamaisa tlhahiso ka phallo e bonolo bakeng sa ts'ebetso e ntle.

• Sephetho se Phahameng: Eketsa bokhoni ba tlhahiso ntle le ho senya boleng.

• Keketseho ea Pigment e Eketsehileng: Fumana mebala e ruileng ka thepa e fokolang, ho fokotsa litšenyehelo.

→Bakeng sa Lipolasetiki tsa Boenjiniere le Li-Polymers: Matlafatsa Boleng le Bokhabane
• Sephanyi se Ntlafetseng: Fumana botle bo holimo, bo benyang lihlahisoa tsa hau.

• Phallo e Ntle ea Mold: Etsa bonnete ba hore mekhoa ea tlhahiso e bonolo le ho fokotsa liphoso.

• Phokotso ea Viscosity: Ntlafatsa ts'ebetso le ho fokotsa tšebeliso ea matla.

• Sehlahisoa se Phahameng sa Tlhahiso: Hlophisa mohala oa hau oa tlhahiso bakeng sa tlhahiso e phahameng.

• Sekhoa sa Pigment se Fokotsoeng: Boloka bots'epehi ba mebala bakeng sa mebala e khanyang, e tšoarellang.

• Phahamiso e Phahameng: Eketsa ts'ebetso e tsitsitseng ea 'mala le lisebelisoa.

Hobaneng o Khetha Li-hyperdispersants tsa SILIKE tsa Silicone?

• Ho boloka litšenyehelo: Ntlafatsa ts'ebetso le ho fokotsa litšila tsa thepa.

• Eco-Friendly: Finyella lipheo tsa ts'ebetso ka mekhoa e ntlafalitsoeng ea tlhahiso.

• Tšebeliso e fapaneng: E ​​loketse mefuta e mengata ea li-polymers le liindasteri.

4. Fetola Mekhahlelo ea Ts'ebetso

Screw Speed: Eketsa lebelo la screw (hangata 200-500 rpm) ho matlafatsa ho kuta le ho hasana. Qoba lebelo le feteletseng, kaha sena se ka lebisa ho senyeha ha mocheso.

Nako ea Bolulo: Ntlafatsa nako ea ho lula ka har'a extruder (hangata metsotsoana e 30-60) ho etsa bonnete ba ho kopanya hantle ntle le ho chesa.

Filtration: Sebelisa lipakete tsa skrine (mohlala, 100-200 mesh) ho tlosa likaroloana tse sa qhalang le ho netefatsa boleng bo tšoanang ba masterbatch.

5. Shebana le Mathata a Thepa le Tlhokomelo

Lisebelisoa tse Hloekileng: Kamehla hloekisa li-extruder, screws, 'me u shoe ho thibela tšoaetso kapa ho bokellana ha lintho tse senyehileng tse amang ho hasana.

Wear Check: Lekola li-screws le libarele hore na ha li senyehile, kaha thepa e tsofetseng e fokotsa ts'ebetso ea ho kuta 'me e lebisa ho phatlalatseng hampe.

Ho Fepa ho Nepahetseng: Sebelisa li-feeders tsa gravimetric bakeng sa pigment e nepahetseng le dosing ea resin, ho netefatsa ho ts'oara ha pigment hasane.
