Indlela yokuphucula ukusasazwa kweeretardants zomlilo

Ngokusetyenziswa okubanzi kwezinto zepolymer kunye neemveliso zabathengi be-elektroniki kubomi bemihla ngemihla, izehlo zomlilo nazo ziyanda, kwaye umonakalo owuzisayo woyikisa ngakumbi. Ukusebenza kwe-flame retardant kwezixhobo ze-polymer kuye kwabaluleke ngakumbi nangakumbi, kukuphumeza iimfuno zeplastiki kunye neemveliso zerabha, ukunciphisa ungcoliseko lothuli olubangelwa yi-flame retardants, i-flame retardant masterbatch yabakho, kwaye idlala into ebalulekileyo. kunye nendima ebalulekileyo ekubunjweni kweemveliso zokugqibela.

I-masterbatch ye-flame retardant yenziwa ngokwefomula efanelekileyo, ngokusebenzisa indibaniselwano yendalo ye-flame retardant, i-lubricant dispersant kunye ne-carrier, ngokucoca okuxineneyo, ukuxuba, ukufana kunye ne-extrusion granulation. Kule, i-dipersant idlala indima ebaluleke kakhulu, yongeza inxalenye ethile ye-dispersant ingaba yinto enhle kakhulu ukukhuthaza ukusasazeka kwe-flame retardant, ukuze kube lula ukusabalalisa ngokulinganayo kwinkqubo, ukuthintela ukuxutywa kwe-flame retardant, ngcono isiphumo sakusasaza, ukwenzela ukwenza iimolekyuli ze-flame retardant zidlale isiphumo esingcono se-flame retardant, ngaloo ndlela kuphuculwe ukusebenza kakuhle kwe-flame retardant yeplastiki, iimveliso zerabha, umlilo uya kukrwitshwa kwisigaba sokuqala.

Nangona kunjalo, ekusebenzeni, iiplastiki ezininzi kunye neengxenye zerabha eziqukethe amacandelo e-flame-retardant azikwazi ukwenza iimpawu zabo zokutshatyalaliswa komlilo ngenxa yokusabalalisa okungalinganiyo kwe-flame-retardant kwizinto ezibonakalayo emlilweni, okukhokelela kumlilo omkhulu kunye nelahleko enkulu.

Ukuze kukhuthazwe ukusasazwa okufanayo kweeretardants zomlilo okanye i-masterbatch ye-flame retardant kwinkqubo yokubumba imveliso, ukunciphisa ukwenzeka kokusasazwa okungalinganiyo okubangelwa yimpembelelo ye-flame retardant ayikwazi ukusetyenziswa ngokufanelekileyo, njl., kunye nokuphucula umgangatho weemveliso ze-flame retardant, I-SILIKE iphuhlise isongezelelo se-silicone esilungisiweyo SILIMER hyperdispersant.

I-SILIMER luhlobo lwe-tri-block copolymerized modified siloxane eyenziwe nge-polysiloxanes, amaqela e-polar kunye namaqela amade ekhabhoni. Amacandelo e-polysiloxane chain chain angakwazi ukudlala indima ethile yodwa phakathi kweamolekyuli ezivuthayo zomlilo phantsi kwe-shear mechanical, ukukhusela i-agglomeration yesibini ye-athomu ye-flame retardant; amacandelo e-polar chain chain ane-bonding ethile kunye ne-flame retardant, edlala indima yokudibanisa; amacandelo amade ekhabhoni anokuhambelana okuhle kakhulu kunye nezinto ezisisiseko.

Olu luhlu lweemveliso zifanelekile kwii-resin ze-thermoplastic eziqhelekileyo, i-TPE, i-TPU kunye nezinye i-elastomers ze-thermoplastic, kwaye inokuphucula ukuhambelana phakathi kwee-pigments / ii-powders zokugcwalisa / i-powders esebenzayo kunye neenkqubo ze-resin, kunye nokugcina imeko yokusabalalisa i-powders ezinzile.

Kwangaxeshanye, inokunciphisa i-viscosity yokunyibilika, inciphise i-torque ye-extruder, uxinzelelo lwe-extrusion, iphucule ukusetyenzwa kwezinto, kunye nokuthambisa okulungileyo, kwaye kwangaxeshanye inokuphucula ngokufanelekileyo ukuvakalelwa kwesixhobo. umphezulu wezinto, kunye nomgangatho othile wokuguda kwaye awuchaphazeli iipropati zomatshini wezinto eziphathekayo, kukukhuthaza ukusasazwa okufanayo kwamacandelo elangatye-retardant ukukhuthaza isiphumo somlilo we-retardant yemveliso yokugqibela ukunika umdlalo opheleleyo ukuya phezulu. -izisombululo ezisemgangathweni.

Ukongeza, olu luhlu lweemveliso alufanelekanga kuphela kwi-masterbatch ye-flame retardant, kodwa kunye ne-masterbatch yombala okanye i-concentration ephezulu echithwa kwangaphambili.
