I-Colour Masterbatch iwuhlobo olusha lwe-ejenti yombala ekhethekile yezinto ze-polymer, eyaziwa nangokuthi ukulungiswa kwe-pigment. Iqukethe izakhi ezintathu eziyisisekelo: umbala noma udayi, umthwali kanye nezithasiselo, futhi iyinhlanganisela etholwe ngokunamathisela ngokulinganayo inani elingavamile le-pigment noma udayi ku-resin. Izinsiza zokucubungula ziyadingeka ukuze kuqinisekiswe ukuthi inani elikhulu le-pigment lingahlakazwa ngokufanayo, ukuvimbela ukuhlangana, nokugwema izinkinga ezinjengokuncibilika kokuncibilika kanye Nokunciphisa ukwakheka kokufa ngesikhathi sokucubungula.
Kukhona izithasiselo eziningi emakethe ezingasetshenziswa kumbala masterbatch, hlobo luni lwezithasiselo olungaxazulula kangcono izinkinga ezingenhla?
I-SILIMERuchungechungei-silicone hyperdispersant, Thuthukisa ukusabalalisa okusebenzayo nokufana kwezimpushana ezinombala
Inkinga 1: Imibala yokugeleza kwe-Masterbatch extrusion marks, indawo engeyinhle yomkhiqizo kunqubo yokucubungula i-masterbatch.
Inkinga 2: I-masterbatch ephothayo kulula ukuphuka, ayidlulisi kahle, futhi nevelu yokuhlunga ayilungile.
Ukuhlaziya isizathu: Isizathu esiyinhloko ukuthi usayizi wezinhlayiyana ze-powder yombala mkhulu kakhulu noma i-powder yombala ayihlakazwanga ngokulinganayo futhi i-agglomerates ngendlela ethile ngesikhathi sokucubungula.
Isixazululo: I-SILIKE SILIMER uchungechunge lwe-silicone hyperdispersantiwuhlobo lomkhiqizo we-copolymer polysiloxane oguquliwe, ongathuthukisa ukuhambisana phakathi kwempushana yombala kanye ne-resin substrate, ukhuthaze ukuhlakazeka okusebenzayo nokufana kombala wempuphu futhi uyigcine uzinzile, ngisho ne-chromaticity, ithuthukise amandla ombala we-pigment, thuthukisa i-fluidity yesistimu, ithuthukise ukusebenza kokucubungula, futhi okwamanje, inganciphisa i-surface friction coefficient ngokusebenzisa izici ze-silicon chain's. amandla aphansi ajikelezayo, ukuze akwazi ukuthuthukisa ubushelelezi bomhlaba bemikhiqizo. Futhi ingaqinisekisa ukukhiqizwa okubushelelezi kwe-extrusion spinning.
Njengoba kuboniswe ku-Fig. 1, ngaphansi kwezinga lokushisa lokuhlola: 235℃; isampula ephelele: 1000g; isisindo sombala - 80g; ukufakwa kwe-masterbatch: 20%; i-substrate PP: 80%; Ukucaciswa kwesihlungi: Izimo zokuhlolwa kwe-mesh eziyi-1000, kungabonakala ukuthi ngemuva kokwengezwa kwe-SILIKE silicone hyperdispersantSILIMER6000, SILIMER6400, I-SILIMER5236ku-masterbatch, inani lokuhlunga ingcindezi lehliswe kakhulu, okubonisa ukuthiIFANA ne-silicone hyperdispersantithuthukisa ngempumelelo i-agglomeration ye-powder, futhi ithuthukise ngokwengeziwe i-dispersibility ye-powder. I-dispersant ingasetshenziswa ukuthuthukisa ukuhlakazeka kwempushana.
I-SILIKE PFAS yamahhala ye-PPA Polymer Process Aid, Susa ukuphuka kwencibilika futhi Unwebe Imijikelezo Yokuhlanza Imishini
Inkinga 3: Isikhunta se-masterbatch extrusion outlet sombala siqoqa impahla, futhi umjikelezo wokuhlanza imishini mfushane.
Ukuhlaziya isizathu: Ngenxa yokungahambisani kahle kwempushana yombala nezinto eziyisisekelo, ingxenye yempushana yombala kulula ukuyihlanganisa ngemva kokuxubana, kunomehluko phakathi koketshezi lwempushana yombala kanye ne-resin kanye ne-viscosity yokuncibilika kukhulu. enqubweni ye-extrusion, ngesikhathi esifanayo, kukhona umphumela we-viscous phakathi kwemishini ye-extrusion yensimbi kanye nesistimu ye-resin, okuholela ezintweni ezifile emzimbeni wekamelo kanye nokukhishwa kwe-extrusion umlomo wokufa, impushana yombala kanye ne-thermoplastic resin iyasuswa ngesikhathi senqubo yokukhishwa okuholela ekuqoqweni komlomo kanye nokufa, futhi indima phakathi kwe-resin encibilikayo kanye nempahla yensimbi idinga ukuncishiswa ukuze kugwenywe isimo esinjalo. Kuyadingeka ukwenza buthaka ukusebenzisana phakathi kwe-resin melt kanye nemishini yensimbi ukugwema lesi simo.
Inkinga 4: Ncibilikisa ukuphuka ngesikhathi se-extrusion yesivinini esikhulu, ukuhlukaniswa kwempushana yombala kanye nemvula.
Ukuhlaziya isizathu: Njengoba izinga lokugunda elibucayi lezinto ngokwazo lincane lapho uhlelo lwempushana yombala lukhishwa ngesivinini esikhulu, kuzoba nezinkinga ezinkulu zokuncibilika kwe-ncibilika kanye nezinkinga zokwakha lapho kukhishwa ngesivinini esikhulu, okuzodala ukuhlukaniswa kanye nemvula yempushana yombala. . I-Fluoropolymer iyi-polymer ye-viscosity ephezulu ohlelweni lwe-powder yombala ohlelweni lwekhono lokufuduka kwangaphandle libi, umphumela wokuthuthuka ujwayelekile ngokuqhathaniswa.
Isixazululo: Izinsiza zokucubungula ze-SILIKE PFAS-free PPAiwumkhiqizo owenziwe nge-organically modified copolymerised polysiloxane masterbatch ohlanganisa amasegimenti eketango le-polysiloxane namaqembu amhlophe, ahlanganisa ukusebenza okuhle kakhulu kwakho kokubili, nokuthuthukisa isakhiwo ngesikhathi esifanayo. I-PPA engenayo i-fluorine yamukela amaqembu aguquliwe angahlangana ngokuqinile nezikulufu zensimbi esikhundleni sendima ye-fluorine ku-PPA equkethe i-fluorine, bese isebenzisa izici zamandla eziphansi ze-silicone ukwenza ifilimu ye-silicone ebusweni bempahla yensimbi ukuze ukufeza umphumela wokuzihlukanisa, okwandisa ngokuphumelelayo umjikelezo wokuhlanza wemishini ukuze unciphise isikhathi sokuphumula, ukuqeda ukuphuka kwe-ncibilika, ukunciphisa ukwakheka kokufa, nokuthuthukisa indima yekhwalithi yendawo. Ngaphezu kwalokho, iphinde ibe nezici zokuvikelwa kwemvelo okungeyona i-PFAS, ukunciphisa i-torque ye-extrusion, ukuthuthukisa ukucubungula uketshezi nokunye.
Njengoba kuboniswe kuMfanekiso 2, ngemva kokuba ikhasimende liwusebenzisileSILIKE PFAS-free Polymer Processing Aids, isikhathi esifanayo sokucubungula, i-powder yombala enamathele odongeni lwangaphakathi lomshini ithuthukiswe kakhulu.
Njengoba kuboniswe ku-Fig. 3, ngaphansi kwesimo se-extrusion samaminithi angu-30 kanye nenani elifanayo lokwengezwa, ukuthuthukiswa kwe-SILIKE engeyona i-PFAS PPA ekuhlanganiseni kokufa kungcono kakhulu kunaleyo ye-PPA ene-fluorinated.
Abakhiqizi be-Colour Masterbatch, uma uhlangabezana nezinkinga noma izinkinga ngesikhathi sokucubungula i-masterbatch, sicela usithinte, i-SILIKE ingakunikeza izixazululo zokucubungula ezenziwe ngokwezifiso.
I-Chengdu SILIKE Technology Co., Ltd, i-China ehamba phambiliI-Silicone AdditiveUmhlinzeki wepulasitiki eguquliwe, unikeza izixazululo ezintsha zokuthuthukisa ukusebenza nokusebenza kwezinto zepulasitiki. Siyakwamukela ukuxhumana nathi, i-SILIKE izokunikeza izixazululo ezisebenzayo zokucubungula amapulasitiki.
