Ibhetshi yezinto ezinombala
I-Master batch luhlobo olutsha lwe-colorant eyenzelwe ngokukodwa izinto ze-polymer, eyaziwa ngokuba kukulungiselela i-pigment. Yenziwe ngezinto ezintathu ezisisiseko: ii-pigment okanye iidayi, abathwali kunye nezongezo. Yi-aggregate efunyenwe ngokulayisha ngokulinganayo inani elikhulu lee-pigment okanye iidayi kwii-resin kwaye inokubizwa ngokuba yi-pigment concentrate. Ke ngoko, amandla ayo okudaya angaphezulu kunalawo ee-pigment ngokwazo. Ngamazwi alula: I-color master batch yi-aggregate efunyenwe ngokulayisha ngokulinganayo inani elikhulu le-pigment okanye idayi kwi-resin.
01 Ukwakhiwa
Iimibala okanye iidayi
Iimibala zihlulwe zibe ziimibala eziphilayo kunye nee-inorganic
Iipigment ze-organic ezisetyenziswa rhoqo ziquka: i-phthalocyanine ebomvu, i-phthalocyanine eluhlaza okwesibhakabhaka, i-phthalocyanine eluhlaza okwesibhakabhaka, i-lightfast bright red, i-macromolecular red, i-macromolecular yellow, i-permanent yellow, i-permanent purple, i-azo red, njl.
Iipigment ezisetyenziswa rhoqo ziquka: i-cadmium ebomvu, i-cadmium etyheli, i-titanium dioxide, i-carbon black, i-iron oxide ebomvu, i-iron oxide etyheli, njl.
Umthwali
I-carrier sisiseko se-masterbatch yombala. Ii-masterbatches zombala ezikhethekileyo zihlala zikhetha i-resin efanayo ne-resin yemveliso kunye ne-carrier, kwaye ukuhambelana phakathi kwezi zimbini yeyona nto ilungileyo. Nangona kunjalo, ukuguquguquka kwe-carrier kufanele kuqwalaselwe ngaxeshanye.
Umsasazi
Ukukhuthaza ukusasazeka okufanayo kweepigment nokuthintela ukuba zingajiyi, iqondo lokunyibilika kwe-dispersant kufuneka libe ngaphantsi kunele-resin, kwaye kufuneka lihambelane kakuhle ne-resin kwaye lihambelane kakuhle neepigment. Ezona dispersants zisetyenziswa kakhulu zezi: i-polyethylene wax ene-molecular-weight ephantsi kunye ne-stearate.
Isongezelelo
Ezifana nezithintela ilangatye, ezikhanyisayo, ezilwa neentsholongwane, ezilwa ne-static, ezilwa ne-antioxidant kunye nezinye iintlobo, ngaphandle kokuba umthengi ezicelile, ngokubanzi azinazo ezongezo zingasentla kwi-masterbatch yombala.
02 Iingenelo
a.Ukuze umbala ube nokusasazeka ngcono kwimveliso Ngexesha lenkqubo yokuvelisa imibala ye-masterbatches, imibala kufuneka icocwe ukuze kuphuculwe ukusasazeka kwayo kunye namandla okudaya. Isithwali se-masterbatch yombala ekhethekileyo siyafana nohlobo lweplastiki lwemveliso, oluhambelana kakuhle. Emva kokufudumeza nokunyibilikisa, amasuntswana emibala anokusasazwa kakuhle kwiplastiki yemveliso.
b.Inceda ekugcineni uzinzo lwekhemikhali lwe-pigment. Ukuba ii-pigment zisetyenziswa ngokuthe ngqo, ziya kufunxa amanzi kwaye zi-oxidize ngenxa yokudibana ngqo nomoya ngexesha lokugcina nokusetyenziswa. Nangona kunjalo, emva kokuba zenziwe zibe zii-masterbatches zemibala, i-resin carrier iyazahlula ii-pigment emoyeni nasekufumeni, nto leyo enokugcina umgangatho wee-pigment ungatshintshi ixesha elide.
c.Qinisekisa ukuba umbala wemveliso uzinzile. Amasuntswana eMasterbatch afana namasuntswana eresin, nto leyo eyenza kube lula kwaye kuchaneke ngakumbi xa kulinganiswa. Awanamatheli kwisikhongozeli ngexesha lokuxuba kwaye axutywe ngokulinganayo neresin. Ke ngoko, ukuzinza kobungakanani bokongeza kunokuqinisekiswa, ngaloo ndlela kuqinisekiswa ukuzinza kombala wemveliso.
D.Khusela impilo yabasebenzi. Iimibala zihlala zikwimo yomgubo kwaye zihlala zibhabha xa zongezwa kwaye zixutyiwe. Nje ukuba ziphefumlwe ngumzimba womntu, ziya kuchaphazela impilo yabasebenzi.
kunye.Gcina okusingqongileyo kucocekile
f.Kulula ukuyisebenzisa
Umzi-mveliso wethu usebenzisa iibhatshi zemibala eyahlukeneyo xa esenza iipayipi zeplastiki, nto leyo evumela uyilo olwahlukeneyo kwaye yenza iipayipi zibe nomtsalane ngakumbi.
