I-HydroxyEtheetheetheetheethy (Hec) i-polymer ye-sollomer eqhelene nayo isetyenziswa njenge-thi churner, i-emulsifier, i-stachelizer, njl.
Amanyathelo e-HydroxyEsete disetion
Lungiselela izixhobo kunye nezixhobo:
Hydroxythl sellielse poder
I-Solvent (ihlala amanzi)
Isixhobo esikhuthazayo (esifana nomatshini)
Izixhobo zokulinganisa (zokulinganisa isilinda, ibhalansi, njl.njl)
Isitya
Ukufudumeza isinyibilikisi:
Ukukhawulezisa inkqubo yokuphelisa, i-solvent inokuvutha ngokufanelekileyo, kodwa ngokubanzi akufuneki idlule kwi-50 ° C ukuba iphephe ukonakala kwengqondo. Amaqondo obushushu emanzi phakathi kwe-30 ° C kwaye i-50 ° C eyona nto ilungileyo.
Kancinci wongeza i-hec powder:
Ngokuthe ngcembe ferlinkle hec powder kumanzi ashushu. Ukuthintela ukwahluka, yongeza nge-sieve okanye itshiza kancinci. Qiniseka ukuba umgubo we-hec usasazeka ngokulinganayo ngexesha lenkqubo eshukumisayo.
Qhubeka nokuvuselela:
Ngexesha lenkqubo eshukumisayo, qhubeka ukongeza i-hec powder ukuqinisekisa ukuba umgubo usasazeka kakhulu emanzini. Isantya esifudukayo akufuneki sithintele kakhulu ukunqanda amaqabble kunye ne-agegramration. Isantya esibonakalayo sihlala sicetyiswa.
Ukuchithwana okumileyo: Emva kokusasazeka ngokupheleleyo, ihlala iyimfuneko ukumela ixesha elithile (ihlala iiyure ezininzi okanye ixesha elide) ukuvumela i-hec ukuba iginyisele ngokupheleleyo isisombululo. Ixesha lokuma lixhomekeke kubunzima bemolekyuli ye-hec kunye nokuxinana kwesisombululo.
Ukuhlengahlengisa i-viscofity: Ukuba i-viscofity kufuneka ilungiswe, inani lehekc linokunyuka ngokufanelekileyo okanye linciphile. Ukongeza, inokuhlengahlengiswa ngokwenza ukongeza i-elektrolytes, itshintshe ixabiso le-pH, njl njl.
Ukuthintela ukutshitshiswa
Kulumkele ukuphazamiseka: i-hydroxyyteetheethy seluplome kulula, xa usongeza i-powder, hlawula ingqalelo ekhethekileyo kuyo ngokulinganayo. Isikhuselo okanye esinye isixhobo sokusasazeka sinokusetyenziselwa ukunceda ukusasazeka ngokulinganayo.
Iqondo lobushushu: Iqondo lobushushu le-SOLPNP alinakuphakama kakhulu, kungenjalo kunokubangela ukonakala kwe-hec kwaye kuchaphazele ukusebenza kwesisombululo. Ihlala ifanelekile ukuyilawula phakathi kwe-30 ° C kwaye i-50 ° C.
Thintela umoya ukuba ungangeni: Kulumkele ukuvuselela ngokukhawuleza ukuthintela umoya ukuba ungangenisi isisombululo senzelwe amaqamza. Iibhubhu ziya kuchaphazela ukufana nokungafihlisi zesisombululo.
Khetha izixhobo ezifanelekileyo zokuvuselela: Khetha izixhobo ezifanelekileyo zokuvuselela ngokomzobo wesisombululo. Izisombululo ze-viscofity ephantsi, zinokusetyenziswa izikhuselo eziqhelekileyo; Kwisisombululo se-viscofity, umnqweno onamandla unokudingeka.
Ukugcina kunye nokuLondolozwa:
Isisombululo se-HEC esichithiweyo kufuneka sigcinwe kwisitya esitywiniweyo ukuthintela ukufuma okanye ungcoliseko. Xa igcinwe ixesha elide, kuphephe ukukhanya kwelanga ngqo kunye nemeko yobushushu obuphezulu yokuqinisekisa uzinzo lwesisombululo.
Iingxaki eziqhelekileyo kunye nezisombululo
Ukuchithwa okungalinganiyo:
Ukuba ukuchithwa okungalinganiyo kwenzeka, kunokuba kuba umgubo uthe wafakwa ngokukhawuleza okanye ovuselelekileyo. Isisombululo kukuphucula ukufana kokukhuthaza, ukwandisa ixesha elitshatileyo, okanye ukulungisa isantya somgubo ongezelelweyo ngexesha lokuvuselela.
Isizukulwana seBubble:
Ukuba inani elikhulu leebhabhu zivele kwisisombululo, amaqabu anokuncitshiswa ngokucothisa ngesantya esitshatileyo okanye alawule ixesha elide. Amaqabu esele ehambile, iarhente yokufaka isidima inokusetyenziswa okanye unyango lwe-ultrasonic lungasetyenziselwa ukubashenxisa.
Isisombululo i-velosity iphezulu kakhulu okanye iphantsi kakhulu:
Xa isicombululo singafezekisi iimfuno, sinokulawulwa ngokuhlengahlengisa inani le-hec. Ukongeza, uhlengahlengiso ixabiso le-pH kunye namandla e-Ionic yesisombululo kunokuchaphazela kwakhona i-vickosity.
Ungayichitha gwenxa i-hydroxythyl seluplose kwaye ufumane isisombululo esifanayo nesizinzileyo. Ukusebenzisana amanyathelo afanelekileyo okwenza izinto kunye nezilumkiso kunokwandisa isiphumo se-hydroxytethy kwizicelo ezahlukeneyo.
