Ubwino wogwiritsa ntchito mono masterbatch popaka utoto wapulasitiki ndi chiyani?

Mono masterbatch ndi mtundu wa utoto wa pulasitiki womwe umakhala ndi pigment imodzi kapena zowonjezera, zomangidwa mu utomoni wonyamulira. Amagwiritsidwa ntchito kuwonjezera mtundu wofanana ndi zinthu zina ku mapulasitiki panthawi yopanga.

High concentrated mono masterbatch ndi mtundu wazinthu zopaka utoto za pulasitiki zomwe zimapereka mitundu yayikulu komanso yotsika mtengo. Ndi yabwino kwa ntchito monga jekeseni akamaumba, extrusion, nkhonya akamaumba ndi kuponyera rotational kumene yunifolomu ndi kusasinthasintha mu mankhwala yomalizidwa ndi zofunika. Mono masterbatch imakhala ndi zigawo ziwiri: chonyamulira utomoni ndi pigment kapena utoto tinthu. Utoto wonyamulira umagwira ntchito ngati chopangira chopangira inert chomwaza utotowo mofanana mu matrix onse a polima pokonza. Izi zimatsimikizira zotsatira zamtundu wosasintha ndikusiyana pang'ono kuchokera pagulu kupita pagulu.

Ma Mono masterbatches nthawi zambiri amakhala ndi 40% pigment kapena utoto, zomwe zimagwira ntchito bwino kwambiri poyerekeza ndi zinthu zanthawi zonse zokhala ndi mitundu yomwe nthawi zambiri imakhala ndi 1-10%. Kupanga kwapamwamba kokhazikika kwa mono masterbatch kumaphatikizapo kusakaniza zokhala ndi zonyamulira zofananira pa kutentha kokwera mu chosakanizira chozama mpaka homogeneity ikwaniritsidwa. Izi zimapanga gulu lokhazikika lomwe lingagwiritsidwe ntchito molunjika popanda kuwonjezera njira zomwe zimafunikira musanagwiritse ntchito pomaliza. Ma mono masterbatches apamwamba kwambiri amapereka dispersibility yabwino mu mapulasitiki chifukwa cha kakulidwe kakang'ono ka tinthu kakang'ono komwe kamathandizira kuchepetsa zovuta zomwe zimafala mukamagwiritsa ntchito ma pellets achikuda kapena mankhwala opangidwa kale. Kuphatikiza apo, amapereka kuyanjana bwino ndi zida zina ndikusungabe mawonekedwe owoneka bwino monga kuwala, kuwonekera komanso kukhazikika kwa UV pakapita nthawi ngakhale m'malo ovuta kwambiri achilengedwe - kuwapangitsa kukhala abwino kwa ntchito zakunja monga zikwangwani kapena zida zam'munda zomwe zimawonekera padzuwa ndi mvula. tsiku ndi tsiku. Kuphatikiza apo, mitundu iyi imakhala ndi mphamvu yokoka yocheperako kuposa utomoni wa namwali womwe umathandizira mapangidwe opepuka koma amakwaniritsa zokometsera zomwe amafunikira mkati mwachitukuko chachifupi - kupulumutsa ndalama & nthawi!
