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 kangaka emakethe ezingase zisetshenziselwe masterbatch umbala, hlobo luni izithasiselo ezingaxazulula 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 ayihlakazeki 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, ithuthukise ukugeleza kwesistimu, ithuthukise ukusebenza kokucubungula, futhi okwamanje, inganciphisa i-coefficient yokungqubuzana kwendawo ngokusebenzisa izici zamandla okujikeleza aphansi weketango le-silicon, ukuze ithuthukise ubushelelezi bendawo yemikhiqizo. 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, kunomphumela we-viscous phakathi kwemishini ye-extrusion yensimbi kanye nesistimu ye-resin, okuholela ezintweni ezifile emzimbeni wegumbi kanye nokukhishwa komlomo wokufa, i-powder yombala kanye ne-thermoplastic. i-resin iyasuswa ngesikhathi senqubo yokukhishwa okuholela ekuqongeleleni komlomo kanye nokufa, futhi indima phakathi kwe-resin encibilikayo nezinto zensimbi 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 elingeziwe, 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.
