Umbala we-Masterbatch luhlobo olutsha lwe-ejenti ekhethekileyo yokufaka imibala kwizinto ze-polymer, eyaziwa ngokuba yi-pigment yokulungisa. Iqulethe izinto ezintathu ezisisiseko: i-pigment okanye idayi, i-carrier kunye ne-additives, kwaye i-aggregate efunyenwe ngokudibanisa inani elingaqhelekanga le-pigment okanye idayi kwi-resin. Izixhobo zokucubungula ziyafuneka ukuze kuqinisekiswe ukuba isixa esikhulu se-pigment sinokusasazwa ngokufanayo, ukuthintela ukudityaniswa kwe-agglomeration, kunye nokuphepha iingxaki ezinjengokunyibilika kokuqhekeka kunye nokunciphisa ukwakhiwa kokufa ngexesha lokucubungula.

Kukho izongezo ezininzi kwiimarike ezingasetyenziselwa umbala we-masterbatch, luhlobo luni lwezongezo olunokusombulula ngcono ezi ngxaki zingasentla?

SILIMERuthothoi-silicone hyperdispersant, Khuthaza ukusasazwa okusebenzayo kunye okufanayo komgubo wombala

Ingxaki 1: Umbala we-Masterbatch we-extrusion flow marks, umgangatho ombi wemveliso kwinkqubo ye-masterbatch processing.

Ingxaki yesi-2: I-masterbatch ejikelezayo kulula ukuyiqhawula, i-extruding engalunganga, kwaye ixabiso lokucoca alilungile.

Uhlalutyo lwesizathu: Esona sizathu siphambili kukuba ubungakanani besuntswana lomgubo wombala bukhulu kakhulu okanye umgubo wombala awusasazwanga ngokulinganayo kwaye ulungelelanise kwicala elithile ngexesha lokucubungula.

Isisombululo: SILIKE SILIMER uchungechunge lwe-silicone hyperdispersantluhlobo lwemveliso ye-copolymer polysiloxane eguquliweyo, enokuphucula ukuhambelana phakathi komgubo wombala kunye ne-resin substrate, ikhuthaze ukusasazwa okusebenzayo kunye nokufanayo komgubo wombala kwaye uyigcine izinzile, kunye ne-chromaticity, ukuphucula amandla ombala we-pigment, ukuphucula ulwelo lwenkqubo, ukuphucula ukusebenza kokusetyenzwa, kwaye okwangoku, inokunciphisa i-coefficient ye-friction yomhlaba ngokusebenzisa iimpawu ze-silicon chain. amandla aphantsi ajikelezayo, ukuze aphucule ukuguda komphezulu weemveliso. Kwaye inokuqinisekisa imveliso egudileyo ye-extrusion spinning.

Njengoko kubonisiwe kumfanekiso 1, phantsi kobushushu bovavanyo: 235℃; isampulu iyonke: 1000g; ubunzima bebala: 80g; ukongeza kwi-masterbatch: 20%; substrate PP: 80%; ukucaciswa kokucoca: Iimeko ze-1000 zovavanyo lwe-mesh, kunokubonwa ukuba emva kokongezwa kwe-SILIKE silicone hyperdispersantSILIMER6000, SILIMER6400, SILIMER5236kwi-masterbatch, ixabiso lokuhluza uxinzelelo liye lancitshiswa kakhulu, nto leyo ebonisa ukubaSILIKE i-silicone hyperdispersantngokufanelekileyo iphucula i-agglomeration phenomenon ye powder, kwaye iphucula ngakumbi i-dispersibility yomgubo. I-dispersant ingasetyenziselwa ukuphucula i-dispersibility yomgubo.

SILIKE PFAS yasimahla yoNcedo lweNkqubo yePolymer yePPA, Susa ukunyibilika kokwaphuka kunye nokwandisa imijikelo yokuCoca isiXhobo

Ingxaki yesi-3: Umbala we-masterbatch extrusion outlet mold iqokelela izinto, kwaye umjikelezo wokucoca izixhobo umfutshane.

Uhlalutyo lwesizathu: Ngenxa yokungahambelani kakubi komgubo wombala kunye nesiseko sezinto, inxalenye yomgubo wombala kulula ukudityaniswa emva kokuxubana, kukho umahluko phakathi kokuguquguquka komgubo wombala kunye ne-resin kunye ne-viscosity yokunyibilika okukhulu. kwinkqubo ye-extrusion, kwangaxeshanye, kukho impembelelo ye-viscous phakathi kwezixhobo ze-metal extrusion kunye nenkqubo ye-resin, ekhokelela kwizinto ezifileyo kumzimba wegumbi kunye nokukhutshwa kwesixhobo. umlomo fa, umgubo umbala kunye nentlaka thermoplastic zihluthwe ngexesha lenkqubo extrusion okubangela emlonyeni kunye fa ukuqokelelana izinto, kunye nendima phakathi intlaka anyibilike kunye nezixhobo zentsimbi kufuneka kuncitshiswe ukuphepha imeko enjalo. Kuyimfuneko ukuba buthathaka ukusebenzisana phakathi kwe-resin melt kunye nezixhobo zetsimbi ukuphepha le meko.

Ingxaki yesi-4: I-Melt fracture ngexesha lokukhupha i-high-speed extrusion, ukuhlukana komgubo wombala kunye nemvula.

Uhlalutyo lwesizathu: Njengoko isantya esibalulekileyo sokucheba sezinto ngokwazo sincinci xa inkqubo yomgubo wombala ikhutshelwa ngesantya esiphezulu, kuya kubakho ukuqhekeka okunzulu kunye neengxaki zokufa xa zikhutshelwa ngesantya esiphezulu, okuya kubangela ukwahlukana kunye nemvula yombala womgubo. . I-Fluoropolymer yipolymer ephezulu ye-viscosity kwinkqubo yomgubo wombala kwinkqubo yokukwazi ukufuduka ngaphandle ihlwempuzekile, umphumo wokuphucula uqhelekileyo.

Isisombululo: I-SILIKE PFAS-i-PPA yasimahla yezixhobo zokusebenzayimveliso ye-copolymerised ye-polysiloxane masterbatch ehlaziyiweyo edibanisa i-polysiloxane chain segments kunye namaqela e-polar, ukudibanisa ukusebenza okugqwesileyo kokubini, kunye nokuphucula isakhiwo ngexesha elinye. I-PPA engenaFluorine yamkela amaqela alungisiweyo anokudibanisa ngamandla ngakumbi kunye nezikrufu zetsimbi ukuze athathe indawo yendima yefluorine kwi-PPA enefluorine, emva koko isebenzise iimpawu zamandla asezantsi e-silicone ukwenza ifilimu ye-silicone kumphezulu wezixhobo zetsimbi ukufezekisa umphumo wokuzihlukanisa, okwandisa ngokufanelekileyo umjikelo wokucoca wezixhobo zokunciphisa ixesha lokunciphisa, ukuphelisa ukuphuka kwe-melt, ukunciphisa ukwakhiwa kweefa, kunye nokuphucula indima yomgangatho womphezulu. Ukongeza, ikwanayo neempawu zokukhuselwa kokusingqongileyo okungeyo-PFAS, ukunciphisa i-torque ye-extrusion, ukuphucula ukusetyenzwa kwamanzi njalo njalo.

Njengoko kuboniswe kuMfanekiso 2, emva kokuba umthengi esetyenzisiweI-SILIKE PFAS-free Polymer Processing Aids, ixesha elifanayo lokucubungula, umgubo wombala onamathele kudonga lwangaphakathi lomatshini uphuculwe kakhulu.

Njengoko kubonisiwe kwi-Fig. 3, phantsi kwe-30 min imeko ye-extrusion kunye nesixa esifanayo sokongeza, ukuphuculwa kwe-SILIKE engeyo-PFAS yePPA kwi-die build-up ingcono kakhulu kune-PPA ene-fluorinated.

Abavelisi bemibala ye-Masterbatch, ukuba uhlangabezana nazo naziphi na iingxaki okanye iingxaki ngexesha lokusetyenzwa kwe-masterbatch, nceda uqhagamshelane nathi, i-SILIKE inokukunika izisombululo ezicwangcisiweyo.
