Mau oyamba a Colour Masterbatch Omwe Anagwiritsidwa Ntchito Kufananiza Zingwe Zapulasitiki

Kodi colorbatch ndi chiyani?

Colour masterbatch, ndi mtundu watsopano wa polymer material special colorant, yomwe imadziwikanso kuti kukonzekera pigment.

Amapangidwa ndi zinthu zitatu zofunika: pigment kapena utoto, chonyamulira ndi zowonjezera. Ndiwophatikizidwira wamtundu wapamwamba wokhazikika kapena utoto womwe umalumikizidwa ndi utomoni. Ikhoza kutchedwa kuti pigment concentrate, kotero mphamvu yake yopaka utoto ndiyokwera kuposa pigment yokha.

Mwachidule, mtundu wa masterbatch ndi mtundu wa pigment kapena utoto womwe umagwirizanitsidwa mofanana ndi utomoni.

Kodi zigawo zikuluzikulu za colorbatch ndi chiyani?

Zoyambira zamtundu wa masterbatch:

1. Pigment kapena utoto

Ma pigment amagawidwa kukhala ma organic pigments ndi inorganic pigments.

Ambiri ntchito organic inki ndi: phthalocyanine wofiira, phthalocyanine buluu, phthalocyanine wobiriwira, mofulumira wofiira, macromolecular wofiira, macromolecular yellow, okhazikika yellow, okhazikika chibakuwa, azo red ndi zina zotero.

Nthawi zambiri amagwiritsidwa ntchito inorganic pigments ndi: cadmium red, cadmium yellow, titaniyamu dioxide, mpweya wakuda, chitsulo okusayidi wofiira, chitsulo okusayidi yellow ndi zina zotero.

2. Cchotengera

Chonyamulira ndi masanjidwe a mtundu masterbatch. Special mtundu masterbatch zambiri amasankha utomoni womwewo monga mankhwala utomoni monga chonyamulira, ngakhale awiri ndi bwino, komanso kuganizira fluidity wa chonyamulira.

3. Dwokhazikika

Limbikitsani mtundu wa pigment womwazikana komanso wosasunthika, malo osungunuka a dispersant ayenera kukhala otsika kuposa utomoni, ndipo utomoni umakhala wogwirizana bwino, ndipo pigment ili ndi mgwirizano wabwino. Ma dispersants omwe amagwiritsidwa ntchito kwambiri ndi polyethylene low molecular sera ndi stearate.

4. Additive

Monga retardant lawi, kuwala, antibacterial, antistatic, antioxidant ndi mitundu ina, kupatula ngati pempho kasitomala, zambiri lilibe zina pamwamba pa mtundu masterbatch.

Kodi mitundu ndi magiredi amtundu wa masterbatch ndi ati?

Njira zogawira mtundu wa masterbatch zimagwiritsidwa ntchito motere:

Gulu mwachonyamulira: monga PE master, PP master, ABS master, PVC master, EVA master, etc.

Gulu pogwiritsa ntchito: monga jekeseni mbuye, kuwomba akamaumba mbuye, kupota mbuye, etc.

Mtundu uliwonse ukhoza kugawidwa m'magulu osiyanasiyana, monga:

1. Mtundu wapamwamba wa jakisoni masterbatch:Amagwiritsidwa ntchito pamabokosi opangira zodzikongoletsera, zoseweretsa, zotchingira zamagetsi ndi zinthu zina zapamwamba.

2. Wamba jekeseni mtundu masterbatch:Amagwiritsidwa ntchito popanga zinthu zamapulasitiki tsiku lililonse, zotengera zamafakitale, etc.

3. Advanced blow film color masterbatch:amagwiritsidwa ntchito popaka utoto wowonda wa zinthu zowonda kwambiri.

4. Wamba filimu yowomba mtundu masterbatch:amagwiritsidwa ntchito popanga matumba ambiri, matumba opaka utoto.

5. Spinning colorbatch:amagwiritsidwa ntchito ngati utoto wopota ulusi wa nsalu, tinthu tating'onoting'ono tamtundu wa pigment bwino, ndende yayikulu, mphamvu yopaka utoto, kukana kutentha, kukana kuwala.

6. Low-grade colorbatch:amagwiritsidwa ntchito popanga zinthu zotsika kwambiri zokhala ndi zofunikira zamtundu wochepa, monga zinyalala, zotengera zotsika, ndi zina.

7. Special colorbatch:molingana ndi mitundu ya pulasitiki yotchulidwa ndi wogwiritsa ntchito pazinthu, sankhani pulasitiki yofanana ndi chonyamulira chopangidwa ndi mtundu wapamwamba. Mwachitsanzo, PP master ndi ABS master motero amasankha PP ndi ABS ngati zonyamulira.

8. Universal colorbatch:utomoni (nthawi zambiri PE wokhala ndi malo otsika osungunuka) umagwiritsidwanso ntchito ngati chonyamulira, koma ungagwiritsidwe ntchito pa utoto wa ma resin ena kuphatikiza utomoni wonyamulira.

Universal colorbatch ndi yosavuta komanso yosavuta, koma ili ndi zovuta zambiri. Mulingo wokana kutentha kwa mtundu wapadera wa masterbatch nthawi zambiri umakhala woyenera mapulasitiki omwe amagwiritsidwa ntchito pazogulitsa, ndipo atha kugwiritsidwa ntchito pakutentha koyenera. Kusiyanasiyana kwa kusinthika kwamtundu kungayambike pazifukwa zotsatirazi, chimodzi ndi kutentha kwachilendo, kumodzi ndi nthawi yopuma ndi yaitali kwambiri.

9. Poyerekeza ndi utoto wa granulation, mtundu wa masterbatch uli ndi zotsatirazi:

(1) Kupaka utoto ndi kukonza kwazinthu kumatsirizika kamodzi, kupewa kutentha kwa granulation ndi utoto wa pulasitiki, kuteteza mtundu wa zinthu zapulasitiki ndi zabwino.

(2) Njira yopangira zinthu zapulasitiki ndiyosavuta kwambiri.

(3) Itha kupulumutsa magetsi ambiri.

Chifukwa chiyani ntchitomtundu masterbatch?

 Kugwiritsa ntchito mtundu masterbatch kuli ndi zotsatirazi:

1. Kubalalika bwino kwa pigment muzinthu

Colour masterbatch ndi gulu lomwe limapangidwa polumikiza kuchuluka kwa pigment mosiyanasiyana ku utomoni.

Popanga mtundu wa masterbatch, pigment iyenera kuyengedwa kuti ipititse patsogolo kubalalitsidwa ndi mphamvu ya utoto wa pigment. Chonyamulira cha masterbatch chapadera cha mtundu ndi chimodzimodzi ndi pulasitiki ya mankhwala, ndipo ali ndi zofanana zabwino. Pambuyo pa kutentha ndi kusungunuka, tinthu tating'ono ta pigment titha kumwazikana bwino mu pulasitiki ya mankhwalawa.

2. Mkukhala ndi kukhazikika kwa mankhwala a pigment

Ngati pigment ikugwiritsidwa ntchito mwachindunji, pigment idzatenga madzi ndi oxidizing chifukwa cha kukhudzana kwake mwachindunji ndi mpweya panthawi yosungira ndikugwiritsa ntchito. Pambuyo pakupanga mtundu wa masterbatch, chonyamulira utomoni amalekanitsa pigment mlengalenga ndi madzi, kuti mtundu wa pigment ukhale wosasinthika kwa nthawi yayitali.

3. Onetsetsani kukhazikika kwa mtundu wa mankhwala

Mtundu wa masterbatch ndi wofanana ndi tinthu ta utomoni, womwe ndi wosavuta komanso wolondola pakuyeza. Posakaniza, sichidzatsatira chidebecho, ndipo kusakanikirana ndi utomoni kumakhala kofanana kwambiri, kotero kungathe kutsimikizira kukhazikika kwa kuchuluka kwa ndalama zowonjezera, kuti zitsimikizire kukhazikika kwa mtundu wa mankhwala.

4. Tetezani thanzi la wogwiritsa ntchito

Pigment nthawi zambiri imakhala yaufa, yomwe imakhala yosavuta kuwuluka ikawonjezeredwa ndi kusakaniza, ndipo imakhudza thanzi la wogwiritsa ntchito pambuyo pokokedwa ndi thupi la munthu.

5. Sungani chilengedwe chaukhondo ndi ziwiya zopanda banga

6. Njira yosavuta, yosavuta kutembenuza mtundu, imapulumutsa nthawi ndi zipangizo

Chifukwa cha pigment mu ndondomeko yosungirako ndi ntchito kukhudzana mwachindunji ndi mpweya, kotero padzakhala chinyezi mayamwidwe, makutidwe ndi okosijeni, clumping ndi zochitika zina, ntchito mwachindunji adzaoneka padziko pulasitiki mankhwala mawanga mtundu, mtundu mdima, mtundu mosavuta. kuzimiririka, ndi kuyambitsa fumbi likuwuluka posakaniza, zomwe zimakhudza thanzi la wogwiritsa ntchito.

Ndipo mtundu masterbatch mu ndondomeko kupanga kudzera mawotchi processing, pigment anali woyengedwa, pigment ndi utomoni chonyamulira, dispersant ndi osakaniza mokwanira, kotero kuti pigment ndi mpweya, kudzipatula madzi, motero utithandize pigment nyengo kukana, kusintha kubalalitsidwa ndi mitundu. mphamvu ya pigment, mtundu wowala. Chifukwa cha mawonekedwe ofanana a mtundu wa masterbatch ndi ma resin pellets, ndizosavuta komanso zolondola pakuyezera. Posakaniza, sizimamatira ku chidebecho, choncho zimasunga nthawi yoyeretsa chidebe ndi makina ndi zipangizo zomwe zimagwiritsidwa ntchito mu makina oyeretsera.
