Wenza njani isisombululo seHec?

I-hec (i-hydroxyyl seluplose) yindawo eqhelekileyo ye-gickener kunye ne-enulsifiezer, esetyenziswa ngokubanzi kulungiselelo lwezisombululo, ii-emuls, i-gels, njl njl.

1. Ukulungiselela
Ngaphambi kokuba uqalise ukulungiselela isisombululo se-hec, qiniseka ukuba uzilungiselele ezi zixhobo zilandelayo kunye nezixhobo:
I-hec yomgubo (imigaqo-nkqubo ye-HEC ekhoyo ye-HEC idla ngokuba namabakala ahlukeneyo okufakwa, kwaye imveliso efanelekileyo kufuneka ikhethwe ngokwesicelo esithile)
I-Solvent (ihlala inamanzi acocekileyo, amanzi e-deoerser okanye ezinye izicelo ezifanelekileyo)
Isixhobo esikhuthazayo (i-magnetic skirrer okanye umatshini womatshini)
Isixhobo solawulo lobushushu (njengokuhlamba amanzi)
Isitya (iglasi okanye iplastiki evuselela ivolumu eyaneleyo)
Ukuchaneka kwe-elektroniki (ekubumbeni okuchanekileyo komgubo we-hec)

2. Amanyathelo asisiseko amalungiselelo esisombululo
2.1 Khetha i-Solvent
I-hec inomoya olungileyo emanzini, kodwa ukwenzela ukuthintela ukuphazamiseka okanye ukusasazeka okungahambelaniyo ngexesha lokuchithwa, uku-odola ukongeza kunye nesantya esishukumisayo kufuneka silawulwe ngononophelo. Amanzi e-deoerd ahlala esetyenziswa njengesinyibilikisi. Ukuba ufuna ukulungiselela isisombululo se-SORCIC SCHECT SET SCHECT SYSTU, kufuneka ukhethe inkqubo efanelekileyo yeSolvent (njengenkqubo yomxube ye-ethanol namanzi).

2.2 Ukufudumeza Amanzi
Inqanaba lokuchithwa kwe-hec lihambelana nobushushu bamanzi. Ukwenzela ukukhawulezisa ukutshitshiswa kwe-hec, amanzi afudumeleyo (malunga ne-50 ° C) ihlala isetyenziswa, kodwa kungaphezulu kakhulu ukunqanda ukusebenzela ukusebenza kwe-hec. Beka amanzi e-deeersied kwisitya, qala ngokufudumeza, kwaye uhlengahlengise kubushushu obufanelekileyo (40-50 ° C).

2.3 Ukuvuselela ngokuthe chu
Ngelixa amanzi ashushu, qala ukushukumisa. Isixhobo esifumileyo sinokuba sisibambiso semagnethi okanye isibongozo somatshini. Isantya esimdaka esifanelekileyo kufuneka sigcinwe sikuphephe ukutshiza kakhulu kwamanzi ngelixa kuqinisekisa ukuxuba iyunifomu.

2.4 ngokuthe chu yongeza i-hec powder
Xa amanzi efudunyelelwa ukuba angama-40-50 ° C, qala kancinci ukongeza i-hec powder. Ukuthintela ukuphazamiseka kwe-powder, kufuneka ifakwe ngokuthe ngcembe ngelixa ishukumisa. Ezi ndlela zilandelayo zinokusetyenziselwa ukuphucula iziphumo zokusasazwa:

Yongeza kwiibatch: ungathulu konke ngaxeshanye, ungongeza kwinani elincinci amaxesha, kwaye ulinde de umgubo usasazeke kwaye ukongeza kwixesha elizayo.
Sieve: Spinkible umgubo we-hec nge-sieve emanzini ukunceda ukunciphisa ukwahlula umgubo we-powder.
Lungisa isantya esitshatileyo: Xa ufesa umgubo, lungisa isantya esitshatileyo ngokufanelekileyo ukugcina amandla athile afungelweyo, olwalukuhlela ukwanda kunye nokusasazwa kwemolekyuli.

2.5 Qhubeka nokuxhokonxa kude kube kuchithwe ngokupheleleyo
Ukupheliswa kwe-hec yinkqubo ehamba kancinci. Njengoko ipowler ichithwe kwaye ichithwe, isisombululo siya kuthotywa ngokuthe chu. Ukuqinisekisa ukuba i-HC inyibilikile ngokupheleleyo, qhubeka ishukumisa malunga neeyure eziyi-1-2, kwaye ixesha elithile lixhomekeke kuhlobo lwesisombululo kunye nenani le-hec elisetyenzisiweyo. Ukuba amagqabantshintshi avele kwisisombululo okanye isisombululo asichithiwe ngokungavumi, ixesha elitshatileyo linokwandiswa ngokufanelekileyo okanye iqondo lobushushu lamanzi linokunyuka lingaphezulu kwe-50 ° i-C.

2.6 Ukupholisa
Xa i-HC ichithwe ngokupheleleyo, yeka ukufudumeza kwaye iyaqhubeka nokushukumisa, kwaye isisombululo sipholile kancinci kubushushu begumbi. Ngexesha lenkqubo yokupholisa, i-viscosity yesisombululo inokuqhubeka nokunyuka ide ifikelele kwilizwe elizinzileyo.

3. Lungisa uxinzelelo lwesisombululo
Ukugxininiswa kwesisombululo se-hec kudla ngokuhlengahlengiswa ngokwesicelo esithile. Uluhlu lwe-hec ye-hec eqhelekileyo yi-0.5% 5%, kwaye ixabiso elithile limiselwa ngokwesiphumo esifunekayo. Oku kulandelayo yifomula yokubala imali efunekayo ye

Hec:

Isixa se-hec (g) = ivolumu yesisombululo (ml) =

Umzekelo, ukuba ufuna ukulungiselela i-1000ml ye-1% yesisombululo se-HEC, ufuna i-10G yomgubo we-hec.

Ukuba i-viscosity yesisombululo iphezulu kakhulu okanye iphantsi kakhulu emva kokulungiselela, unokuhlengahlengisa ngezi ndlela zilandelayo:

Ukutyibilika: Ukuba i-vickosity ayonelanga, yongeza inani elincinci lomgubo. Lumka ukongeza kwiibatch ukunqanda ukwahluka.

I-dilution: Ukuba i-vickosity yesisombululo iphezulu kakhulu, yongeza amanzi e-deoried ukuze uyisebenzise ngokufanelekileyo.

4. Isisombululo
Ukuqinisekisa ukufana nokucoceka kwesisombululo sokugqibela, kunokubekwa kwi-sheve okanye iphepha lokucoca. Ukupeyinta kunokususa amasuntswana okanye ukungcola, ngakumbi kwizicelo ezifunwayo (ezinje ngamayeza okanye i-cosmetics).

I-5. Ukulondolozwa nokugcinwa
Isisombululo se-hec esilungisiweyo kufuneka sitywinwe ukukhusela uguquko kunye nongcoliseko. Kuyacetyiswa ukuba uyigcine kwindawo epholileyo neyomileyo kude nelanga ngqo. Ukuba isisombululo sigcinwe ixesha elide, ungcoliseko oluncinci lunokwenzeka. Kucetyiswa ukongeza isixa esifanelekileyo sexabiso lezinto ezigciniweyo (njenge-phenoxyethanol, iMethyliatiazotiazoline, njl.) Njengoko kufuneka.

I-6. Izilumkiso
Kulumkele ukuphazamiseka: i-hec powder kulula kakhulu ukuba ingaphazamisi emanzini, ngakumbi xa yongeza ngokukhawuleza okanye ivuseleleke ayonelanga. Kucetyiswa ukuba usebenzise indlela yokongeza kwiibatchs kwaye uhlengahlengise isantya esitshatileyo ngokufanelekileyo ukuqinisekisa ukuba umgubo usasazeka ngokulinganayo.
IMilinganiselo ye-Viscosity: Ukuba kukho imfuneko, uVekyusi wesisombululo unokulinganiswa ngokusebenzisa izixhobo ezifana nokuchithela kokujikeleziswa ukuqinisekisa ukuba iyazifezekisa iimfuno zesicelo.
Ukulondolozwa: Ukuba isisombululo se-HEC sigcinwa ixesha elide, ukongezwa kwezinto ezigciniweyo kubaluleke kakhulu ukuthintela ukukhula kwezinto ezincinci kwisisombululo kwaye kubangele ukuba isisombululo siphezulu.

Isitshixo sokwenza isisombululo se-hec kukulawula ubushushu besinyikizi, isantya esishukumisayo kunye nendlela eyongezwayo yomgubo we-HEC ukuqinisekisa ukuba i-HEC inokusasazeka kakhulu kwaye inyibilikisiwe ngokupheleleyo. I-AgeGlomeration kufuneka ithintelwe ngexesha lenkqubo yokupheliswa, kwaye umgangatho wesisombululo unokuphuculwa ngokucoca ukuba kukho imfuneko. Emva kokuzibandakanya ezi ndlela, ungazilungiselela ngempumelelo izisombululo ze-hec ezihlangabezana nazo iimfuno zakho kwaye uzisebenzise kwiimveliso ezahlukeneyo zemizi-mveliso kunye neyemihla ngemihla.
