Ho hasana ha 'mala ke phephetso ea bohlokoa empa hangata e sa nyenyefatsoe tlhahisong ea masterbatch. Ho hasana ho fokolang ho ka lebisa mathateng a kang kabo e sa lekanang ea 'mala, li-filter tse koetsoeng, ho robeha ha faeba likhoeleng tse sothiloeng, le li-welded seams tse fokolang. Mathata ana ha a ame feela boleng ba sehlahisoa empa hape a eketsa litšenyehelo tsa tlhahiso ka lebaka la tšebeliso e phahameng ea 'mala le nako ea ho se sebetse ha mechini. Ka tlase ke tataiso e khutšoanyane ea ho sebetsana le liphephetso tsena ka katleho, ho latela mekhoa ea indasteri:

1. Ntlafatsa Khetho ea Pigment
Kgetha Dipigmente tse Tsamaellanang: Kgetha dipigmente tse tsamaellanang le motheo wa polymer (mohlala, PE, PP, PET) ho netefatsa hore di kolobiswa hantle le ho hasana.

Boholo ba Likaroloana le Kalafo ea Bokaholimo: Sebelisa mebala e nang le boholo bo bonyenyane ba likaroloana bakeng sa ho hasana hamolemo. Mebala e phekotsoeng holim'a bokaholimo (mohlala, ka li-dispersant kapa li-coat) e thusa ho fokotsa ho kopana le ho ntlafatsa litšobotsi tsa phallo.

Ho Kenya Dipigment: Qoba ho feta mojaro o kgothaletswang wa pigment (hangata 20-40% bakeng sa dipigment tsa tlhaho, 50-80% bakeng sa tse sa pheleng). Ho kenya dintho tse ngata ho ka baka ho kopana le ho hasana ho fokolang.

2. Ntlafatsa ho Kopanya le ho Kopanya
Ho Kopanya ka Sekere se Seholo: Sebelisa di-extruder tse nang le di-screw tse pedi kapa di-mixer tse nang le sekere se phahameng ho qhaqha di-agglomerate tsa pigment. Fetola sebopeho sa di-screw (mohlala, di-block tsa ho kguma) ho ntlafatsa ho kuta le ho ntlafatsa ho hasana.

Ho Kopanya Pele: Kopanya di-pigment le di-dispersant kapa di-carrier resins pele di etswa ho ntlafatsa ho kolobisa ha pele le ho fokotsa ho kopana ha tsona.

Taolo ea Mocheso: Boloka mocheso o motle oa ho qhibiliha ho qoba ho senyeha ha 'mala kapa mathata a ho teteana. Bakeng sa mebala e amehang mochesong (mohlala, mebala e itseng ea tlhaho), boloka mocheso o le ka tlase ho meeli ea ho senyeha ha 'ona.

3. Sebelisa Lisebelisoa tsa ho Hasanya
Lintho tse eketsoang: Kenya metsoako e hasanyang e kang boka, li-stearate, kapa li-dispersant tsa polymeric (mohlala, boka ba polyethylene, lintho tse eketsoang tse thehiloeng ho EVA) ho fokotsa ho teteana le ho ntlafatsa ho kolobisa ha pigment.
Tekanyo: Hangata, sebelisa 1-5% ea dispersant ka boima, ho latela mofuta oa 'mala le mojaro. Ho e sebelisa ho feta tekano ho ka ama litšobotsi tsa mechine hampe 'me ho ka baka ho thunya (bothata ba ponahalo ea bokaholimo).
Hyperdispersant e Ncha bakeng sa Masterbatch: Letoto la SILIKE SILIMER – Lisebelisoa tsa ho sebetsana le ho qhalakanya tse sebetsang hantle le tse sebetsang hantle.

Letoto la SILIKE SILIMERLithuso tsa ho sebetsana le lisebelisoa le li-agent tsa ho qhalakanyake di-wax tse thehilweng ho silicone tsa moloko o latelang (tseo hape di bitswang Silicone Hyperdispersants) tse entsweng ho fana ka pigment e ntle le ho hasana ha filler tlhahisong ya masterbatch. E loketse bakeng sa di-concentrate tsa mmala, metswako e tlatsitsweng, dipolasetiki tsa boenjiniere, le ditshebetso tse hlokang ho hasana. Di-hyperdispers tsena di ntlafatsa botsitso ba mocheso, rheology, le bokgoni ba ditjeo ha di ntse di fedisa mathata a ho falla a tlwaelehileng ka di-additives tsa setso (mohlala, di-wax, di-amides, di-ester).

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

Eketsa Bokgoni ba ho Hlophisa Dintho tse Kotsi tsa Pigment bakeng sa Mefuta e sa Tšoaneng ya Disebediswa:

→ Bakeng sa Li-Polyolefin: Phahamisa Boleng ba Pigment ea Hao
• Ho Kolobisa Pigment ka Matla: Finyella mebala e boreleli le e khanyang haholoanyane ka tšebelisano e ntlafalitsoeng.

• Ho Hasana ho Ntlafetseng: Thibela ho kopana ha 'mala oa pigment, ho netefatsa 'mala o ts'oanang le botsitso.

• Phokotso ea Viscosity: Nolofatsa tlhahiso ka phallo e boreleli bakeng sa ts'ebetso e betere.

• Tlhahiso e Phahameng: Eketsa bokgoni ba tlhahiso ntle le ho beha boleng kotsing.

• Keketseho ea Ponahalo ea 'Mala: Finyella mebala e metle ka thepa e fokolang, e leng se fokotsang litšenyehelo.

→Bakeng sa Boenjiniere ba Lipolasitiki le Li-polymer: Ho Eketsa Boleng le Bokgoni
• Khanya e Ntlafetseng ea Bokaholimo: Finyella qetello e ntle le e benyang lihlahisoa tsa hau.

• Ho Lokolloa ha Hlobo ho Molemo: Netefatsa hore lits'ebetso tsa tlhahiso li boreleli le ho fokotsa liphoso.

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

• Tlhahiso e Phahameng: Ntlafatsa mohala oa hau oa tlhahiso bakeng sa tlhahiso e phahameng.

• Sekere sa Pigment se Fokoditsweng: Boloka boleng ba dipigment bakeng sa mebala e khanyang le e tšoarellang.

• Ho Hasana ho Phahameng: Ho eketsa botsitso ba 'mala le ts'ebetso ea thepa.

Hobaneng o lokela ho kgetha di-Silicone Hyperdispersants tsa SILIKE?

• E bolokang litšenyehelo: E ntlafatsa bokhoni le ho fokotsa tšenyo ea thepa.

• E Sireletsa Tikoloho: Finyella lipheo tsa botsitso ka mekhoa e ntlafalitsoeng ea tlhahiso.

• Tšebeliso e Tenyetsehang: E ​​loketse mefuta e mengata ea li-polymer le liindasteri.

4. Fetola Liparamente tsa Ts'ebetso

Lebelo la Sekurufu: Eketsa lebelo la sekurufu (hangata 200-500 rpm) ho ntlafatsa ho kuta le ho hasana. Qoba lebelo le feteletseng, kaha sena se ka lebisa ho senyeha ha mocheso.

Nako ea Bolulo: Ntlafatsa nako ea bolulo ka har'a extruder (hangata metsotsoana e 30-60) ho netefatsa hore e tsoakoa ka botlalo ntle le ho chesa haholo.

Ho sefa: Sebelisa lipakete tsa skrine (mohlala, letlooeng la 100-200) ho tlosa likaroloana tse sa hasanngoang le ho netefatsa boleng ba masterbatch bo lekanang.

5. Sebetsana le Mathata a Lisebelisoa le Tlhokomelo

Lisebelisoa tse Hloekileng: Kamehla hloekisa lisebelisoa tse ntšang lintho tse ling, likurufu le li-die ho thibela tšilafalo kapa ho bokellana ha thepa e senyehileng e amang ho hasana.

Tlhahlobo ea ho Roala: Hlahloba likurufu le libarele hore na lia robeha, kaha lisebelisoa tse tsofetseng li fokotsa katleho ea ho seha 'me li lebisa ho hasana ho fokolang.

Ho Nepahala ha Phepo: Sebelisa li-feeder tsa gravimetric bakeng sa tekanyo e nepahetseng ea pigment le resin, ho netefatsa hore pigment e ntse e hasana hantle.
