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 sokuchithachitha, ukuze wenze iimolekyuli ezinqanda amadangatye ukuba zidlale isiphumo esingcono sokurhoxisa idangatye, ngaloo ndlela kuphuculwe ukubuyiswa komlilo. ukusebenza kakuhle kweplastiki, iimveliso zerabha, umlilo uya kukrwitshwa kwinqanaba lokuqala.

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 ngeepolysiloxanes, 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 nesiseko sezinto.

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 sedangatye sokugqibela. imveliso ukunika ukudlala ngokupheleleyo izisombululo ezikumgangatho ophezulu.

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