Indlela yokuphucula ukusasazeka kwezinto ezithintela ilangatye

Ngenxa yokusetyenziswa ngokubanzi kwezinto zepolymer kunye neemveliso ze-elektroniki kubomi bemihla ngemihla, ukwanda komlilo nako kuyanda, kwaye umonakalo owuzisayo uyoyikisa nangakumbi. Ukusebenza kwezinto zepolymer ezithintela umlilo kuye kwaba yinto ebaluleke ngakumbi, kungenxa yokufezekisa iimfuno zeplastiki kunye neemveliso zerabha ezithintela umlilo, ukunciphisa ungcoliseko lothuli olubangelwa zizinto ezithintela umlilo, i-masterbatch ethintela umlilo yavela, kwaye idlala indima ebalulekileyo ekubunjweni kweemveliso zokugqibela.

I-masterbatch ethintela ilangatye yenziwe ngokwefomula efanelekileyo, ngokusebenzisa indibaniselwano yendalo ye-flame retardant, i-lubricant dispersant kunye ne-carrier, ngokusebenzisa ukucocwa okuxineneyo, ukuxuba, ukufana kunye ne-extrusion granulation. Kule nto, i-dispersant idlala indima ebaluleke kakhulu, ukongeza umlinganiselo othile we-dispersant kunokuba kuhle kakhulu ukukhuthaza ukusasazeka kwe-flame retardant, ukuze kube lula ukusasazeka ngokulinganayo kwinkqubo, ukuthintela ukuhlangana kwe-flame retardant, kokukhona isiphumo sokusasazeka singcono, ukuze iimolekyuli ezithintela ilangatye zidlale isiphumo esingcono se-flame retardant, ngaloo ndlela kuphuculwe ukusebenza kwe-flame retardant yeplastiki, iimveliso zerabha, umlilo uya kukrwitshwa kwisigaba sokuqala.

Nangona kunjalo, ngokwesiqhelo, iiplastiki ezininzi kunye neenxalenye zerabha eziqulethe izinto ezithintela umlilo azikwazi ukwenza iipropati zazo ezithintela umlilo ngenxa yokusasazeka okungalinganiyo kwezinto ezithintela umlilo kwizinto ezikumlilo, nto leyo ebangela umlilo omkhulu kunye nelahleko enkulu.

Ukuze kukhuthazwe ukusasazeka okufanayo kwezinto ezithintela ilangatye okanye i-masterbatch ethintela ilangatye kwinkqubo yokubumba imveliso, kuncitshiswe ukwenzeka kokusasazeka okungalinganiyo okubangelwa yimpembelelo yokuthintela ilangatye engenakukwazi ukusetyenziswa ngokufanelekileyo, njl., kwaye kuphuculwe umgangatho weemveliso ezithintela ilangatye, i-SILIKE iphuhlise i-silicone eguquliweyo ye-SILIMER hyperdispersant.

I-SILIMER luhlobo lwe-siloxane eguqulweyo ye-tri-block copolymerized eyenziwe yi-polysiloxanes, amaqela e-polar kunye namaqela e-long carbon chain. Amacandelo e-polysiloxane chain anokudlala indima ethile yokwahlula phakathi kwee-molecules ezithintela ilangatye phantsi kwe-mechanical shear, nto leyo ethintela ukuhlanganiswa kwesibini kwee-molecules ezithintela ilangatye; amacandelo e-polar chain anobudlelwane obuthile ne-flame retardant, edlala indima yokudibanisa; amacandelo e-long carbon chain anokuhambelana okuhle kakhulu nezinto ezisisiseko.

Olu luhlu lweemveliso lufanelekile kwiiresini ze-thermoplastic eziqhelekileyo, i-TPE, i-TPU kunye nezinye ii-elastomers ze-thermoplastic, kwaye lunokuphucula ukuhambelana phakathi kweepigment/iipowders zokuzalisa/iipowders ezisebenzayo kunye neenkqubo ze-resin, kwaye lugcine imeko yokusasazeka kweepowders izinzile.

Kwangaxeshanye, inokunciphisa i-viscosity ye-melt, inciphise i-torque ye-extruder, uxinzelelo lwe-extrusion, iphucule ukusebenza kwe-processing yezinto, kunye ne-processing lubrication elungileyo, kwaye kwangaxeshanye inokuphucula ngempumelelo imvakalelo yomphezulu wezinto, ngomlinganiselo othile wobushelevu kwaye ayichaphazeli iimpawu zoomatshini zezinto, kukukhuthaza ukusasazeka okufanayo kwezinto ezithintela ilangatye ukukhuthaza isiphumo sokuthintela ilangatye semveliso yokugqibela ukunika umdlalo opheleleyo kwizisombululo ezikumgangatho ophezulu.

Ukongeza, olu luhlu lweemveliso alufanelekanga kuphela kwi-masterbatch ethintela ilangatye, kodwa lukwalungele ne-masterbatch yombala okanye izinto ezisasazeke kwangaphambili ezinoxinzelelo oluphezulu.
