I-HydroxyEtheetheetheetheetheetheethl seluplose (hec) i-polymer esetyenziswe ngokubanzi, i-poly-all-allmer esuswe kwi-selly. Izicelo zayo eziphambili kwiimveliso zekhemikhali zemihla ngemihla zivela ekukhuleni kwazo ukuguqula iRheeology, zizinzi zokuzinzisa, kunye nokuphucula ubume beemveliso.
Iipropathi kunye nendlela ye-hec
I-Hec iphawuleka ngokuthamba kwayo, ukumiswa, ukubopha, kunye nokuxhasa iipropathi. Ibonisa i-pseudoplasticity ephezulu, intsingiselo yokufakwa kwayo incipha phantsi koxinzelelo lwe-Shear kodwa ibuyela kwimeko yayo yoqobo xa uxinzelelo lususiwe. Le ndawo iyingenelo kwiifom ezahlukeneyo njengoko ivumela iimveliso ukuba zihlale zibanzi kwaye zizinzile kwishalofini kodwa kulula ukuyisebenzisa.
Indlela eyayisemva kwe-HEC ilele kwisakhiwo sayo seemolekyuli. Imixokelelwane yePolymer yenza inethiwekhi enokutyikitya amanzi kunye nezinye izinto, ukwenza i-matrix efana nejeyi. Olu sekhelo lwenethiwekhi luxhomekeke kwinqanaba lokufakwa endaweni kunye nobunzima bemoya, enokuthi ilungiswe ukuze kufezekiswe i-viscofity kunye nokuzinza.
Impembelelo kwi-viscofity
Isiphumo sokutyibilika
I-HEC iyaphembelela i-viscosity yeemveliso zemichiza zemihla ngemihla ngokuthambisa isigaba se-accous. Kwiimveliso zononophelo lobuqu njengeziqhwithi kunye ne-shotions, i-SEC yonyusa i-viscofity, ekhokelela kwisiphelo kunye nokuphuculwa kwembono yabathengi. Oku kukhanya kufezekisiwe nge-hddicals yamasuntswana e-hec, apho iimolekyuli zamanzi zinxibelelana ne-Selelose TellumE, ebangela i-polymer ukuba idumbe kwaye yenze isisombululo se-viscous.
Ukuxinezeleka kwe-hec ekuqulunqweni kubalulekile ekufezekiseni i-vickosity oyifunayo. Kubuxakeka obuphantsi, i-HEC ikakhulu inyusa ukubonakala kwenqanaba lamanzi ngaphandle kokufumana iipropathi zokuhamba. Kwiimeko eziphezulu, i-HEC idala ubume-njengengqokelela, ukubonelela ngohlobo oluzinzileyo nolungaguqukiyo. Umzekelo, kwi-shampoos, ukugxininiswa kwe-heci uxinzelelo ukusuka kwi-0.2% ukuya kwi-0.5% kunokubonelela nge-viscofity eyaneleyo yesicelo esigudileyo, ngelixa uxinzelelo oluphezulu lungasetyenziselwa ii-gels okanye iikhrim ezinqabileyo.
Ukuziphatha kwe-shear
Uhlobo lwe-pseudeolististic ye-HEC luvumela iimveliso zemichiza zemichiza ukuze zibonakalise indlela yokuziphatha ye-Shear. Oku kuthetha ukuba phantsi kwesenzo somatshini, ukumpompela, okanye ukusasazeka, ukumiswa kwe-viscosity, ukwenza kube lula ukuyiphatha. Nje ukuba amandla eShear isusiwe, i-viscosity ibuyela kwimeko yayo yoqobo, iqinisekisa imveliso ihlala izinzile kwisitya.
Umzekelo, kwi-SOAPS yoLwandle, i-HEC inceda ekufezekiseni ibhalansi phakathi kwemveliso enesitayile, eqinile kwibhotile kunye nolwelo, isemazantsi esele isuswe ngokulula xa idluliselwa. Le ndawo ibaluleke ngakumbi kwiziko apho kunokwenzeka khona ukuba lula ukusetyenziswa kwesicelo, njengokuhlala kunye ne-geses yeenwele.
Impembelelo kuzinzo
Ukumiswa kunye nokuthathwa
I-HEC iphucula uzinzo lweemveliso zekhemizi zemihla ngemihla ngokusebenza njengearhente yokumisa kunye nokuzinzisa. Ithintela ukwahlulwa kwamasuntswana aqinileyo kunye nendlela yokufumana i-raalescets ye-oyile kwimikhono, ngaloo ndlela igcina imveliso ehamba ngethemba. Oku kubaluleke kakhulu kwimisebenzi equkethe i-insollous, i-pigments, okanye inqunyanyisiwe.
Kwi-rivos kunye ne-crems, i-HEC ihlala i-emulssions ngokwandisa i-viscofity yenqanaba eliqhubekayo, ngaloo ndlela kuncipha ukushukuma kwamathontsi kunye namasuntswana asasazekileyo. Le ndlela yokuzimisela ibalulekile ekugcineni ukuguquguquka kunye nokusebenza kwemveliso kubo bonke ubomi beshelheli. Umzekelo, kwi-sunscreen i-ots, i-HEC iyanceda ukugcina iifilitha ze-UV ezisasazwe ngokufanayo, ukuqinisekisa ukhuseleko olungaguqukiyo kwimitha eyingozi.
Ukugcinwa komswakama kunye nokwenziwa kwefilimu
I-HEC nayo inegalelo kuzinzo lwefomu ngokuphucula ukugcinwa komswakama kwaye yenze ifilimu yokukhusela elusu okanye iinwele. Kwiimveliso zokhathalelo lweenwele, le mpahla yokwakha ifilimu inceda ukwemeko kwaye igcine i-hairstyle ngokuthimba umswakama kunye nokubonelela ngesithintelo kwindalo esingqongileyo.
Kwiimveliso ze-SkerCare, i-HC ye-HEC iphucula ukusebenza kwemveliso ngokunciphisa ilahleko yamanzi ukusuka kulusu, ukubonelela ngefuthe elinde lokungapheliyo. Olu phawu luyingenelo kwiimveliso ezifana ne-mointrierizers kunye nemaski yobuso, apho ukugcina umdlalo we-hydding ngumsebenzi ophambili.
Izicelo kwiimveliso zekhemikhali zemihla ngemihla
Iimveliso zononophelo lomntu
Kwifomu yokhathalelo lomntu, i-HEC isetyenziselwa ngokubanzi ukuthandwa kwayo kunye nokuzinzisa iipropathi. Kwi-shampoos kunye neekhilotithi, ibonelela nge-viscovity oyifunayo, iphucula uzinzo kwi-cum, kwaye iphucula ukuthungwa, kukhokelela kumava angcono othusayo kumsebenzisi.
Kwiimveliso zokhathalelo lwesikhumba ezinjengeekhrim, i-lotions, kunye ne-gels, i-hec isebenza njenge-thi cheki kunye nendawo yokuzibulala, inegalelo kwimveliso egudileyo nenethambeka. Ikwanceda ekusasazeni izithako ezisebenzayo, ukwandisa ukusebenza ngempumelelo kwemveliso.
Iimveliso zasekhaya
Kwiimveliso zokucoca amakhaya, i-HEC idlala indima ekuguquleni i-viscofity kunye nokuzinzisa imisiso. Kwizitolo zokucoca amanzi kunye nolwelo oluhlazo, i-HEC iqinisekisa ukuba imveliso ihlala ilula ukusasaza ngelixa igcina i-viscofity eyaneleyo ukuba ibambelele kumphezulu, ukubonelela ngesenzo esisebenzayo sokucoca.
Kwizilonda zomoya kunye nezithombe zebala, i-HEC inceda ukugcina ukumiswa okufanayo kweyunithi kunye nezinto ezisebenzayo, ekuqinisekiseni ukusebenza okungaguqukiyo kunye namava amnandi.
I-HydroxyEtheetheetheetheetheetheetheetheetheetheethy (hec) licandelo lezinto eziguquguqukayo kunye nexabiso ekuqulunqweni kweemveliso zekhemikhali zemihla ngemihla. Impembelelo yayo kwi-viscofity kunye nozinzo ziyenza ixabiseke ekudaleni iimveliso ezihlangabezana nolindelo lwabathengi ukuze zikwazi ukwenziwa, ukusebenza kunye nokusetyenziswa. Ngokwenza i-viscofity, ukuqinisekisa ukuzinza kwemveliso, kunye nokuphucula iipropathi zezicelo, i-HEC inegalelo elikhulu ekucebiseni ngokufezekileyo kunye nokubhena kwabathengi kuluhlu olubanzi lweemveliso zobuqu kunye neemveliso zasekhaya. Njengoko imfuno yomgangatho ophezulu, ozinzileyo, kwaye isebenza ngobuchule iyaqhubeka nokukhula, indima yeheks kuhlelo lwemveliso inokuthi yandise, ihambisa amathuba amatsha okwenza izinto ezintsha zemichiza.
