Iimolekyuli zedayi ezisasazekayo zincinci, ukwakheka kwedayi ngaphandle kwamaqela anyibilikayo emanzini, ukudaya ngoncedo lwe-dispersant, idayi ngokulinganayo isasazwe kwisisombululo sedayi, ukudaya imicu yepolyester.I-arhente yokusasaza yesodium hexametaphosphatei-arhente encedisayo ukuphucula iimpawu zokusasazeka kwezinto eziqinileyo okanye ezimanzi.
I-ionic dispersant, i-disperant inyibilika emanzini inokuthi ionize i-ion ezintle kunye neeoni ezingalunganga, ezi ion zibhengezwa kumphezulu we-colloid particles ngeentlawulo ezahlukeneyo, kwaye emva koko zenze umbane ophindwe kabini kumphezulu we-ion, okhokelela ekuphuculeni okunokwenzeka.Ukutshatyalaliswa kwe-non-ionic, i-disperant ichithwa emanzini kwaye i-adsorbed phezu kwendawo ye-colloidal particle, ejikeleze i-particle kwaye yenza isithintelo se-steric, sithintele ukudibanisa phakathi kwe-reagent reagent kunye neziko lokuphendula.
I-sodium hetaphosphate yeyepolyphosphate.Ulwakhiwo lwalo lwemolekyuli lusetyhula, kodwa lunolungelelwaniso olude lwekhonkco elide.I-adsorped kumphezulu we-particle ngokusebenzisa iqela lokugqibela, ngelixa i-chain chain ayibandakanyekanga kwi-bonding, enokubonelela nge-electrostatic repulsion eyongezelelweyo.I-ionized anion ye-sodium hetaphosphate inyibilikiswe emanzini adsorbed kwi-particle surface, eyandisa i-electronegativity ye-particle surface.Ukongeza, i-ionized Na + ion inokunyusa ubukhulu bomgangatho ophindwe kabini wombane, kunyesodium hexametaphosphateidlala isiphumo sokusasazeka phantsi kwezi ziphumo zimbini.
Zombini ezi ziphumo ziya kwandisa amandla aphikisayo phakathi kwamaqhekeza, okukhokelela ekukhululweni kwamanzi akhululekile ahlanganiswe kwisakhiwo esidibeneyo, ngokosodium hexametaphosphatei-dispersant inokudlala indima yokusabalalisa amaqhekeza kunye namasuntswana okugcoba.Injongo yayo ephambili kukunciphisa ukunyanzeliswa kobuso phakathi kolwelo - ulwelo kunye nolwelo oluqinileyo.Ngokosodium hexametaphosphatei-dispersant ikwayinto yangaphandle.
Xa ugaya idayi eqinileyo, ukongezasodium hexametaphosphatei-dispersant inokunceda ukutyumza iinqununu kunye nokukhusela iincinci eziqhekekileyo ukuba zidibanise kwaye zigcine ukusabalalisa kuzinzile.Ulwelo oluneoyile olunganyibilikiyo emanzini phantsi konyanzeliso lweshear oluxhokonxayo, lunokusasazwa lube ngamaso amancinane elulwelo, luyeke ukuvuselela, phantsi kwesenzo soxinzelelo lwe-interface ngokukhawuleza, kwaye yongeza i-sodium hetaphosphate dispersant evuselelayo, inokwenza i-emulsion ezinzileyo.
