Vim Li Cas Cov Dispersants Ib Txwm Feem Ntau Ua Tsis Tau Zoo Thiab Yuav Ua Li Cas Hyperdispersants Daws Nws

Hauv kev txhaj tshuaj molding ntawm cov xim masterbatch, cov chaw tsim khoom feem ntau ntsib:

• Cov xim tsis sib xws ntawm cov pawg
• Cov kab xim thiab cov xim me me ntawm cov khoom pwm
• Kev hloov pauv ntawm qhov ci thiab qhov chaw tsaus ntuj
• Kev tawg tsis ruaj khov thaum lub sijhawm txhaj tshuaj siab
• Kev ua haujlwm ntawm lub tshuab txo qis vim tsis sib xws zoo

Txawm tias thaum siv cov tshuaj dispersants lossis cov neeg sawv cev dispersing, kev ua haujlwm feem ntau tsis ua haujlwm nyob rau hauv cov xwm txheej txhaj tshuaj molding tiag tiag.

Vim li cas?

Vim tias feem ntau cov tshuab yog tsim los rau kev tsim cov khoom tawg, tsis yog rau kev tswj hwm kev ruaj khov ntawm cov khoom tawg hauv qab kev ntxhov siab.

Dispersant / Dispersant hauv Polymer Systems

Tus dispersant (lossis tus neeg sawv cev dispersing) yog ib qho khoom siv ua haujlwm uas siv rau hauv cov kab ke polymer uas muaj xim rau:

• Txhim kho cov xim kom ntub
• Txo cov khoom me me uas sib sau ua ke
• Tswj cov xim faib tawm hauv cov polymer matrix kom ruaj khov

Hauv cov yas lag luam, cov khoom ntxiv no feem ntau hu ua:

• Cov tshuaj dispersant xim
• Tus neeg sawv cev rau cov xim masterbatch
• Cov tshuaj ntxiv rau polymer dispersing
• Tus neeg sawv cev ntub thiab tawg

Lawv siv dav hauv cov yas engineering, masterbatch ntau lawm, thiab cov txheej txheem sib xyaw ua ke.

Vim li cas cov tshuaj dispersants ib txwm ua tsis tau zoo hauv kev txhaj tshuaj molding
1. Kev Txwv Tsim Qauv Uas Tsuas Yog Ua Kom Tsis Txhob Muaj Dej Xwb

Feem ntau cov tshuaj dispersants tsuas yog tsom mus rau qhov pib ntub xwb, tsis yog qhov ruaj khov mus sij hawm ntev.

2. Kev Txiav Rov Qab Ua Ib Ke

Thaum lub sijhawm txhaj tshuaj molding:

• Kev ntws siab heev
• Kev caij tsheb kauj vab kub
• Kev hloov pauv ntawm lub zog

→ Cov xim tuaj yeem rov sib sau ua ke txawm tias tom qab ua tiav kev sib xyaw ua ke.

3. Kev Rheology Tsis Ruaj Khov

Muaj ntau cov neeg sawv cev dispersing uas kho qhov viscosity tab sis tsis ua rau cov xim faib tawm ruaj khov thaum lub sijhawm txhaj tshuaj molding.

4. Qhov Sib Txawv ntawm Cov Resin

Cov txheej txheem sib txawv (PP / PE / ABS / PC / PET / PVC) tsim cov cwj pwm tsis sib xws, cuam tshuam rau kev sib xws ntawm cov xim.

Kev Thaiv Mechanism: Vim Li Cas Hyperdispersant Systems Ua Tau Zoo Dua

Cov xim sib cais niaj hnub xav tau cov qauv ruaj khov peb txheej:

1. Kev ntub dej ntawm cov tawv nqaij - Txo cov xim thiab cov polymer interfacial tension
2. De-Agglomeration - Rhuav cov pawg xim rau hauv cov khoom me me
3. Kev Ruaj Ntseg Steric - Tiv thaiv kev rov sib sau ua ke hauv qab kev txiav thiab cua sov

→ Cov tshuaj dispersants ib txwm muaj feem ntau tsuas yog npog Txheej 1 xwb
→ Cov tshuaj hyperdispersants siab heev npog cov txheej 1 + 2 + 3
