General Mkhalidwe wa masterbatch

Mtundu wa pulasitiki womwe umabalalika bwino ndi kuchuluka kwamitundu yambiri kapena zowonjezera ndi ma resins a thermoplastic.Utoto wosankhidwa umakhala ndi kunyowetsa bwino komanso kufalikira kwa utoto, ndipo umagwirizana bwino ndi zinthu zomwe ziyenera kukhala zamitundu.Ndiko kuti: pigment + chonyamulira + chowonjezera =masterbatch

Cmtundu wa ommon

Zida zamtundu zimagwiritsidwa ntchito popanga utomoni wamtundu wachilengedwe ndi utoto wosakanikirana, kukanda, ndi granulated mu mapulasitiki achikuda.Utoto wouma: utoto wa ufa umasakanizidwa mofanana ndi utomoni wamtundu wachilengedwe ndipo umagwiritsidwa ntchito mwachindunji kupanga zinthu zapulasitiki.Mitundu ya Masterbatch ndiyo njira yomwe imagwiritsidwa ntchito kwambiri masiku ano.Mtundu wobalalika mu chonyamuliracho umangosakanikirana ndi utomoni wamtundu wachilengedwe ndipo umagwiritsidwa ntchito popanga zinthu zapulasitiki.

Ubwino wamasterbatch

1. Pangani pigment kukhala kubalalikana bwino mu mankhwala

Pakupanga ma masterbatches amtundu, ma pigment ayenera kuyengedwa kuti apititse patsogolo dispersibility ndi tinting mphamvu ya inki.Chonyamulira cha masterbatch apadera amtundu ndi ofanana ndi pulasitiki wazinthuzo, ndipo ali ndi zofanana zabwino.Pambuyo pa kutentha ndi kusungunuka, tinthu tating'ono ta pigment titha kumwazikana bwino mu pulasitiki ya mankhwalawa.

2. Ndizopindulitsa kusunga kukhazikika kwa mankhwala a pigment

Ngati pigment imagwiritsidwa ntchito mwachindunji, pigment imayamwa madzi ndi oxidize chifukwa cha kukhudzana mwachindunji ndi mpweya panthawi yosungiramo ndikugwiritsa ntchito, ndipo ikapangidwa kukhala mtundu wa masterbatch, khalidwe la pigment likhoza kusungidwa kwa nthawi yaitali chifukwa. chonyamulira utomoni amalekanitsa pigment mpweya ndi chinyezi.Sinthani.

3. Onetsetsani kukhazikika kwa mtundu wa mankhwala

Mtundu wa masterbatch ndi wofanana ndi ma resin granules, omwe ndi osavuta komanso olondola pamiyeso.Sizidzamamatira ku chidebe pamene zimasakanizidwa, ndipo kusakaniza ndi utomoni kumakhala kofanana, kotero kungathe kutsimikizira kukhazikika kwa ndalama zowonjezera, kuti zitsimikizire kukhazikika kwa mtundu wa mankhwala.

4. Tetezani thanzi la wogwiritsa ntchito

Ma pigment nthawi zambiri amakhala ngati ufa, womwe suvuta kuwuluka ukawonjezedwa ndi kusakanizidwa, ndipo umakhudza thanzi la ogwira ntchito pambuyo pokoweredwa ndi thupi la munthu.

5. Sungani chilengedwe mwaukhondo

6. Yosavuta kugwiritsa ntchito

Tzamakono

Ukadaulo womwe umagwiritsidwa ntchito kwambiri wamtundu wa masterbatch ndi njira yonyowa.Mtundu masterbatch amapangidwa ndi madzi gawo akupera, gawo inversion, kutsuka madzi, kuyanika, ndi granulation.Ndi njira iyi yokha yomwe khalidwe la mankhwala likhoza kutsimikiziridwa.Kuonjezera apo, pamene pigment ikuphwanyidwa, mayesero angapo amtundu wa masterbatch ayenera kuchitidwa, monga kuyeza ubwino wa mchenga wopera slurry, kuyeza kufalikira kwa mchenga wopera slurry, kuyeza zolimba za mchenga. akupera slurry, ndi kuyeza fineness wa mtundu phala, etc. polojekiti.

Colour masterbatch nthawi zambiri imakhala ndi magawo atatu, colorant carrier dispersant, osakanizidwa ndi chosakanizira chothamanga kwambiri, wosweka, kutulutsa ndikukokera mu granules, mtundu wa masterbatch uli ndi ndende yayikulu, dispersibility yabwino, zoyera ndi zabwino zina.

Njira zogawira ma masterbatches amtundu zimagwiritsidwa ntchito m'magulu otsatirawa:

Zodziwika ndi chonyamulira: monga PE masterbatch, PP masterbatch, ABS masterbatch, PVC masterbatch, EVA masterbatch, etc.

Gulu pogwiritsa ntchito: monga jekeseni masterbatch, kuwombera masterbatch, spinning masterbatch, etc. Mitundu iliyonse ikhoza kugawidwa m'makalasi osiyanasiyana, monga:

1. MwaukadauloZida jakisoni masterbatch: ntchito kwa zodzikongoletsera ma CD mabokosi, zidole, zipolopolo zamagetsi ndi zinthu zina apamwamba mapeto.

2. Wamba jekeseni masterbatch: ntchito wamba tsiku lililonse mankhwala pulasitiki, muli mafakitale, etc.

3. MwaukadauloZida kuwombedwa filimu mtundu masterbatch: ntchito nkhonya akamaumba mitundu ya zinthu kopitilira muyeso-woonda.

4. Wamba wowombedwa filimu mtundu masterbatch: ntchito nkhonya akamaumba mitundu wa ambiri ma CD matumba ndi matumba nsalu.

5. Spinning masterbatch: amagwiritsidwa ntchito popota ndi utoto wa ulusi wa nsalu.The masterbatch pigment ili ndi tinthu tating'onoting'ono, tinthu tating'onoting'ono tambiri, mphamvu yopangira tinting, kukana kutentha komanso kukana kuwala.

6. Masterbatch amtundu wocheperako: amagwiritsidwa ntchito popanga zinthu zotsika kwambiri zomwe sizimafuna mtundu wamtundu wapamwamba, monga zinyalala, zotengera zotsika, ndi zina zambiri.
