Iindaba

Ukusasazwa kwe-pigment ngumngeni obalulekileyo kodwa osoloko ujongelwa phantsi kwimveliso ye-masterbatch. Ukusasazwa kakubi kunokukhokelela kwimiba enjengokwabiwa kombala ongalinganiyo, izihluzi ezivaliweyo, ikhefu lefayibha kwimicu ephothiweyo, kunye nemithungo edityanisiweyo ebuthathaka. Ezi ngxaki azichaphazeli kuphela umgangatho wemveliso kodwa zinyusa iindleko zemveliso ngenxa yokusetyenziswa okuphezulu kwe-pigment kunye nexesha lokunciphisa koomatshini. Apha ngezantsi sisikhokelo esifutshane sokujongana nale mingeni ngempumelelo, ngokusekwe kwiinkqubo zeshishini:

1. Lungiselela uKhetho lwePigment
Khetha ii-Pigments ezihambelanayo: Khetha ii-pigments ezihambelana nesiseko se-polymer (umzekelo, i-PE, i-PP, i-PET) ukuqinisekisa ukumanzisa okufanelekileyo kunye nokusabalalisa.

Ubungakanani beNcam kunye noNyango loMphezulu: Sebenzisa i-pigments kunye neesayizi ezincinci zamasuntswana ukuze usasazeke ngcono. Ii-pigments ezifakwe phezu komhlaba (umz., kunye ne-dispersants okanye i-coatings) zinceda ukunciphisa i-agglomeration kunye nokuphucula iimpawu zokuhamba.

I-Pigment Loading: Kuphephe ukugqithisa umthamo we-pigment ocetyiswayo (ngokuqhelekileyo i-20-40% ye-organic pigments, 50-80% ye-inorganic). Ukulayisha kakhulu kunokubangela i-agglomeration kunye nokusasazwa kakubi.

2. Ukuphucula ukuxuba kunye nokudibanisa
Ukuxutywa kwe-High-Shear: Sebenzisa i-twin-screw extruders okanye i-high-chear mixers ukophula i-pigment agglomerates. Lungisa ukwakheka kwesijivu (umzekelo, iibhloko zokuxova) ukukhulisa ukucheba kunye nokwandisa ukusasazwa.

Ukuxutywa kwangaphambili: Hlanganisa ii-pigments kunye ne-dispersants okanye i-carrier resins phambi kokukhupha ukuphucula ukumanzisa kokuqala kunye nokunciphisa i-clumping.

Ulawulo lobushushu: Gcina amaqondo obushushu afanelekileyo okunyibilika ukunqanda ukuthotywa kwebala okanye imiba ye-viscosity. Kwibala elingevayo kubushushu (umzekelo, ii-pigments ezithile eziphilayo), gcina amaqondo obushushu angaphantsi kwemida yawo yokuthotywa.

3. Sebenzisa ii-Arhente zokuSasaza
Izongezo: Faka ii-agent ezichithayo ezifana ne-wax, i-stearates, okanye i-polymeric dispersants (umzekelo, i-polyethylene wax, i-EVA-based additives) ukunciphisa i-viscosity kunye nokuphucula i-pigment wetting.
Idosi: Ngokuqhelekileyo, sebenzisa i-1-5% ye-disperant ngobunzima, kuxhomekeke kuhlobo lwe-pigment kunye nokulayisha. Ukusetyenziswa ngokugqithisileyo kunokuchaphazela kakubi iipropati zoomatshini kwaye kunokubangela ukuqhakaza (umba wenkangeleko yomphezulu).
Inoveli ye-Hyperdispersant ye-Masterbatch: I-SILIKE SILIMER Series-Izixhobo zokusebenza eziphezulu zokusebenza kunye nee-agent ezichithayo.

SILIKE SILIMER SeriesIi-Aids zokuLungisa kunye nee-Arhente eziSasazaIsizukulwana esilandelayo se-wax esekwe kwi-silicone (ekwabizwa ngokuba yi-Silicone Hyperdispersants) yenzelwe ukuhambisa i-pigment ephezulu kunye ne-filler dispersion kwimveliso ye-masterbatch. Ilungele ukugxila kombala, iikhompawundi ezizaliswe, iiplastiki zobunjineli, kunye neenkqubo zokusasaza ezifunayo. Ezi hyperdispersants zomeleza uzinzo lwe-thermal, i-rheology, kunye neendleko ezifanelekileyo ngelixa zisusa imiba yokufuduka eqhelekileyo kunye nezongezo zendabuko (umz., i-wax, i-amides, i-esters).

4. Lungisa iiParameters zokuLungisa

Isantya seScrew: Yandisa isantya sokujija (esiqhele ukuba ngama-200-500 rpm) ukukhulisa ukucheba kunye nokusasazwa. Gwema isantya esigqithisileyo, njengoko oku kunokukhokelela ekuthotyweni kwe-thermal.

Ixesha lokuhlala: Lungiselela ixesha lokuhlala kwi-extruder (ngokuqhelekileyo i-30-60 imizuzwana) ukuqinisekisa ukuxuba ngokucokisekileyo ngaphandle kokushisa.

Ukuhluzwa: Sebenzisa iipakethi zesikrini (umzekelo, i-100-200 mesh) ukususa amaqhekeza angasasazwanga kwaye uqinisekise umgangatho ofanayo we-masterbatch.

5. Ukujongana nemiba yeZixhobo kunye noLondolozo

Izixhobo ezicocekileyo: Coca rhoqo ii-extruders, izikrufu, kwaye ufe ukuthintela ukosuleleka okanye ukwakhiwa kwezinto ezonakeleyo ezichaphazela ukusasazwa.

Ukujonga ukunxitywa: Hlola izikrufu kunye nemigqomo ukuba igugile na, njengoko izixhobo ezigugileyo zinciphisa ukusebenza kakuhle kokucheba kwaye zikhokelela ekuhlakazekeni kakubi.

Ukuchaneka kokutya: Sebenzisa i-gravimetric feeders ye-pigment echanekileyo kunye ne-resin dosing, ukuqinisekisa ukuhambelana kwi-pigment dispersion.
