Kutheni ii-Dispersants zeMveli zihlala zingaphumeleli kwaye ii-Hyperdispersants zisombulula njani?

Kwi-injection molding ye-color masterbatch, abavelisi badla ngokujongana nezi zinto zilandelayo:

• Ukungafani kombala phakathi kweebhetshi
• Imicu yemibala kunye namabala kwiindawo ezibunjiweyo
• Ukwahluka kwe-gloss kunye ne-inkungu yomphezulu
• Ukusasazeka okungazinzanga ngexesha lokufakwa kwe-high-shear
• Ukusebenza okunciphileyo koomatshini ngenxa yokungasebenzi kakuhle

Nokuba usebenzisa izinto ezisasaza izinto okanye izinto ezisasaza izinto eziqhelekileyo, ukusebenza kwazo kuhlala kungaphumeleli phantsi kweemeko zokwenyani zokubumba ngenaliti.

Ngoba?

Kuba uninzi lweenkqubo zenzelwe ukwakheka kokusasazeka, kungekhona ukugcina uzinzo lokusasazeka phantsi koxinzelelo lokucubungula.

I-Dispersant/Dispersing Agent kwiiNkqubo zePolymer

I-dispersant (okanye i-arhente yokusasaza) sisongezelelo esisebenzayo esisetyenziswa kwiinkqubo zepolymer eziqulethe i-pigment ukuze:

• Ukuphucula ukumanzisa umbala
• Nciphisa ukuhlangana kwamasuntswana
• Zinzisa ukusasazwa kwepigment kwi-polymer matrix

Kwiiplastiki zoshishino, ezi zongezo zidla ngokubizwa ngokuba:

• Umsasazi wemibala
• Iarhente yokusasaza i-masterbatch yombala
• Isongezelelo sokusasaza i-polymer
• Isixhobo sokumanzisa nokusasaza

Zisetyenziswa kakhulu kwi-engineering plastics, kwi-masterbatch production, nakwiinkqubo zobugcisa ezidityanisiweyo.

Kutheni ii-Dispers zeMveli zingaphumeleli kwi-Injection Molding
1. Umda woYilo lokuNcamisa kuphela

Uninzi lwezinto ezisasaza amanzi lugxila kuphela ekumanziseni kokuqala, kungekhona ekuzinzeni kwexesha elide.

2. Ukuphinda kuhlanganiswe kwakhona kweShear

Ngexesha lokubumba ngenaliti:

• Ukuhamba komoya okuphezulu
• Ukujikeleza kwe-thermal
• Utshintsho loxinzelelo

→ Iimibala zinokuphinda zihlangane nasemva kokuba zihlanganiswe ngempumelelo.

3. Ukungazinzi kweRheology

Ii-agents ezininzi zemveli zokusasazeka zilungisa i-viscosity kodwa ziyasilela ukuzinzisa ukusasazwa kwe-pigment ngexesha lokubumba ngenaliti.

4. Umsantsa wokuhambelana kweResin

Iinkqubo ezahlukeneyo (PP / PE / ABS / PC / PET / PVC) zidala indlela yokusasazeka engaguqukiyo, nto leyo echaphazela ukufana kombala.

I-Mechanism Block: Kutheni ii-Hyperdispersant Systems zisebenza ngcono

Ukusasazwa kwemibala yanamhlanje kufuna imodeli yokuzinzisa enemigangatho emithathu:

1. Ukumanzisa phakathi kobuso – Yehlisa uxinzelelo phakathi kobuso lwe-pigment-polymer
2. Ukususwa kwe-Agglomeration – Yahlulahlula amaqela e-pigment abe ngamasuntswana aphambili
3. Uzinzo lweSteric – Thintela ukuphinda kuhlangane phantsi kobushushu nokuchetywa

→ Izinto zokusasaza zemveli zihlala zigubungela kuphela umaleko 1
→ Ii-hyperdispersants eziphucukileyo zigubungela iileya 1 + 2 + 3
