Amakuru

Gukwirakwiza pigment ni ingorabahizi ariko akenshi idahabwa agaciro mubikorwa bya masterbatch. Gukwirakwiza nabi birashobora gukurura ibibazo nko gukwirakwiza amabara ataringaniye, kuyungurura gufunga, kumenagura fibre muri fibre spun, hamwe no gusudira bidakomeye. Ibi bibazo ntabwo bigira ingaruka gusa kubicuruzwa ahubwo binongera ibiciro byumusaruro bitewe no gukoresha pigment nyinshi hamwe nigihe cyo kumashini. Hano hepfo nubuyobozi bunoze bwo gukemura ibyo bibazo neza, bishingiye kubikorwa byinganda:

1. Hindura uburyo bwo guhitamo pigment
Hitamo Pigment Zihuye: Hitamo pigment ijyanye na polymer base (urugero, PE, PP, PET) kugirango urebe neza kandi bitatanye.

Ingano ya Particle hamwe no Kuvura Ubuso: Koresha pigment ifite ingano ntoya kugirango ikwirakwizwe neza. Ubuso butunganijwe neza (urugero, hamwe na dispersants cyangwa coatings) bifasha kugabanya agglomeration no kunoza imitekerereze.

Kwipakurura Pigment: Irinde kurenza umutwaro wasabwe (mubisanzwe 20-40% kuri pigment organic, 50-80% kuri organic). Kurenza urugero birashobora gutera agglomeration no gutatana nabi.

2. Kongera kuvanga no guteranya
Kuvanga cyane-Shear: Koresha twin-screw extruders cyangwa imvange-yogosha cyane kugirango ugabanye pigment agglomerates. Hindura ibice bya screw (urugero, gukata) kugirango uhindure ubwogoshe kandi utezimbere.

Mbere yo Kuvanga: Kuvanga pigment hamwe nogukwirakwiza cyangwa ibisigarira byabatwara mbere yo kuyikuramo kugirango uteze neza kandi bigabanye.

Kugenzura Ubushyuhe: Komeza ubushyuhe bwiza bwo gushonga kugirango wirinde kwangirika kwa pigment cyangwa ibibazo byijimye. Kubijyanye nubushyuhe bukabije (urugero, pigment zimwe na zimwe), komeza ubushyuhe munsi yurwego rwo kwangirika kwabo.

3. Koresha abakozi batatanye
Inyongeramusaruro: Shyiramo imiti ikwirakwiza ibishashara, ibishashara, cyangwa ibishishwa bya polymeriki (urugero, ibishashara bya polyethylene, inyongeramusaruro zishingiye kuri EVA) kugirango ugabanye ububobere no kunoza ibara.
Igipimo: Mubisanzwe, koresha 1-5% ikwirakwiza kuburemere, ukurikije ubwoko bwa pigment hamwe nuburemere. Gukabya birashobora kugira ingaruka mbi kumiterere yubukanishi kandi bishobora gutera uburabyo (ikibazo cyo kugaragara hejuru).
Ibishya Hyperdispersant ya Masterbatch: SILIKE SILIMER Urukurikirane - Imfashanyo yo gutunganya ibintu byinshi hamwe nogukwirakwiza.

SILIKE SILIMER UrukurikiraneImfashanyo yo gutunganya no gutatanya abakozini ibisekuru bizakurikiraho bishingiye ku bishashara bya silicone (nanone bita Silicone Hyperdispersants) byashizweho kugirango bitange pigment nziza kandi yuzuza ibicuruzwa mu musaruro wa masterbatch. Nibyiza kubibara byamabara, ibice byuzuye, plastike yubuhanga, hamwe nibisabwa byo gutatanya. Izi hyperdispersants zongera ubushyuhe bwumuriro, rheologiya, hamwe nigiciro cyiza mugihe gikuraho ibibazo byimuka bisanzwe hamwe ninyongeramusaruro gakondo (urugero, ibishashara, amide, esters).

Fungura imikorere isumba iyindi hamwe na SILIKE SILIMER Urukurikirane rwa Silicone Hyperdispersants

Kugwiza imbaraga muri Pigment yibanda kubintu bitandukanye:

→ Kuri Polyolefine: Uzamure ubuziranenge bwa pigment
• Kuzamura Pigment Wetting: Kugera kubintu byoroshye, bifite imbaraga nyinshi hamwe nibikorwa byiza.

• Gukwirakwiza neza: Irinde guhunika pigment, kwemeza ibara rimwe kandi rihoraho.

Kugabanya Viscosity: Gutunganya umusaruro hamwe no gutembera neza kugirango bitunganyirizwe neza.

• Ibisohoka byinshi: Ongera ubushobozi bwo kubyaza umusaruro utabangamiye ubuziranenge.

• Kwiyongera kwa Pigment Kwibanda: Kugera kumurongo ukize hamwe nibikoresho bike, kugabanya ibiciro.

→Kuri Engineering Plastike na Polymers: Kuzamura Ubwiza nubushobozi
• Kunoza Ubuso Bwuzuye: Kugera kumurongo wo hejuru, urabagirana kubicuruzwa byawe.

• Kurekura ibicuruzwa byiza: Menya neza uburyo bwo gukora neza no kugabanya inenge.

Kugabanya Viscosity: Kongera gutunganya no kugabanya gukoresha ingufu.

• Ibisohoka Byinshi Umusaruro: Hindura umurongo wawe wo kubyara kugirango winjize byinshi.

• Kugabanya Pigment Shear: Komeza ubusugire bwa pigment kumabara meza, arambye.

• Ikwirakwizwa risumba ayandi: Kugwiza guhuza amabara nibikorwa.

Kuki Hitamo SILIKE ya Silicone Hyperdispersants?

• Ikiguzi-Cyiza: Kunoza imikorere no kugabanya imyanda yibikoresho.

• Ibidukikije byangiza ibidukikije: Kugera ku ntego zirambye hamwe nuburyo bwiza bwo gukora.

• Gushyira mu bikorwa byinshi: Bikwiranye na polymers ninganda zitandukanye.

4. Guhindura ibipimo byo gutunganya

Umuvuduko Wihuta: Ongera umuvuduko wa screw (mubisanzwe 200-500 rpm) kugirango wongere umusatsi no gutatana. Irinde umuvuduko ukabije, kuko ibi bishobora kuganisha ku kwangirika k'ubushyuhe.

Igihe cyo gutura: Hindura igihe cyo gutura muri extruder (mubisanzwe amasegonda 30-60) kugirango urebe neza kuvanga neza nta bushyuhe bukabije.

Filtration: Koresha paki ya ecran (urugero, 100-200 mesh) kugirango ukureho ibice bitagabanijwe kandi urebe neza ubuziranenge bwa masterbatch.

5. Ibikoresho bya aderesi hamwe nibibazo byo kubungabunga

Ibikoresho bisukuye: Buri gihe usukure ibicuruzwa biva hanze, imigozi, kandi bipfe kugirango wirinde kwanduza cyangwa kwiyubaka kw'ibintu byangiritse bigira ingaruka ku gutatanya.

Kugenzura Kwambara: Kugenzura imigozi na barrale kugirango wambare, kuko ibikoresho byambarwa bigabanya imikorere yimisatsi kandi biganisha ku gutatana nabi.

Kugaburira neza: Koresha ibiryo bya gravimetricike kugirango ubone pigment neza kandi ikoreshwe neza, urebe neza ko ikwirakwizwa rya pigment.
