I-HPMC Polymer vissosity njengomsebenzi wobushushu

I-HPMC (i-hydroxypropyl methylcelceltulose) yipoller eqhelekileyo esetyenziswe kwindawo yamayeza, yokutya kunye nemizi-mveliso yenkcitho. Yiselokheli eselokhokho esenziwe nge-scocialculal selsulose yendalo. Enye yeendawo eziphambili ze-HPMC luhlobo lwayo, oluguqukayo ngokuxhomekeke kwizinto ezahlukeneyo ezifana nobushushu.

I-Viscosity ngumlinganiso we-fluid okanye ukuxhathisa kwezinto ngaphandle kokuhamba. Kwi-HPMC Polymers, i-Viscosity yipharamitha echaphazela ukusebenza kwezinto kwizicelo ezahlukeneyo. Uhlobo lwe-HPMC luchaphazelekile zizinto ezininzi ezinje ngobunzima bemolekyuli, isidanga sokufakwa endaweni, kunye nobushushu.

I-Viscosity-Ubume obunobuchule be-HPMC Polymers

I-HPMC Polymers ibonisa ubudlelwane be-nonline phakathi kwe-viscofity kunye neqondo lobushushu. Ngokubanzi, ukwanda kobushushu kubangela ukwehla kwi-viscofity. Oku kuziphatha kunokuchazwa ngu:

I-1. Ubushushu buchaphazela i-hydrogen

Kwi-HPMC Polymers, i-Intermolecular Bonds inoxanduva lokuqulunqa ubume obuqinileyo nenethiwekhi. Ulwazi lwenethiwekhi lunceda ukwandisa i-viscofity yezinto ezibonakalayo. Ukwanda kobushushu babangela ukuba kubekho iibhondi ze-hydrogen ukuze baphule, ngaloo ndlela kuncitshiswe umtsalane we-intermolecular kunye nokunciphisa i-viscofity. Kwelinye icala, ukuncipha kobushushu kubangela ukuba amabhodlo e-hydrogen ye-hydrogen abenzele, okukhokelela kulwando lwe-viscosity.

2. Ubushushu buchaphazela intshukumo yemolekyuli

Kwiqondo lobushushu eliphezulu, iimolekyuli ngaphakathi kwe-HPMC Polymer inamanzi aphezulu eKinetic kwaye unokuhamba ngakumbi. Oku kwandiswa intshukumo yemolekyuli kuphazamisa isakhiwo sePolymer kwaye kunciphisa i-viscofity yayo.

3. Ubushushu buchaphazela iipropathi zeSolvent

Uhlobo lwe-viscosity ye-HPMC Polymer Solutimes nako kuxhomekeke kuhlobo lwesinyibilikisi. Ezinye zezinyithi, ezinjengamanzi, zibonisa ukwehla kwi-viscofity njengoko ubushushu bunyuka ngenxa yokwenza buthathaka iibhondi ze-hydrogen. Ngokwahlukileyo koko, ezinye izinyibilikisi zibonisa ukwanda kwe-viscosity emaqondo aphezulu, njenge-glycerol.

Kufanelekile ukuba uqaphele ukuba iinkcukacha zobudlelwane bamaqondo obushushu obushushu kwi-HPMC zinokuxhomekeka kwinqanaba elithile le-polymer esetyenzisiweyo kunye ne-solvent esetyenzisiweyo. Umzekelo, amanye amabakala e-HPMC abonisa ubushushu obunamandla oxhomekeke, ngelixa ezinye zizinzile ngakumbi. Ngapha koko, ukubonwa kwe-HPMC yonyuswa njengoko uxinzelelo luyanda, kwaye ubudlelwane phakathi kobushushu kunye nokubonisa kwakhona kutshintsha.

Ukubaluleka koVavanyo kwizicelo ze-HPMC

Kumzi-mveliso wamayeza, i-HPMC yipolymer esetyenziswayo kwiinkqubo zokuhambisa iziyobisi, apho kulawulwa kwereyithi yokukhutshwa kweziyo kunye nokuziphatha kuyafuneka. I-Viscofity idlala indima ebalulekileyo kwinqanaba lokukhutshwa kweziyobisi njengoko ichaphazela ukungafani kweziyobisi nge-polymer matrix. Ukongeza, i-viscosity ye-HPMC ikwabalulekile kwiforations, njengoko i-viscofity ephezulu iyafuneka ukuqinisekisa iyunifomu kunye ne-Coades eqhubekayo.

Iimveliso zokutya ezisebenzisa i-HPMC njengearhente yeGelsing kunye ne-eUlsifier ifuna amaxabiso athile okufana ukuze kuqinisekiswe ukuba imveliso ihlala izinzile kwaye ingaguquguquki ukuthungwa kunye nokulungiswa. Ngokukwanjalo, i-cosmetics esebenzisa i-HPMC njengearhente yokuthambisa, ezinje ngee-shampoos kunye ne-outtions, zifuna ukuba uxinzelelo kunye nokubonisa i-HPMC kuyalungiswa ngokweempawu ezifunekayo.

I-HPMC yi-polymer eguquguqukayo ebonisa ubudlelwane phakathi kwe-viscofity kunye neqondo lobushushu. Ukwanda kobushushu kukhokelela ekuncipheni kwe-viscofity, ngokuyintloko ngenxa yefuthe lobushushu kwi-Intermogenar Hydrogen Hyhragen, intshukumo yemolekyuli, kunye nemveliso yemolekyuli, kunye nemveliso yemolekyuli, kunye nemveliso yemolekyuli. Ukuqonda ubudlelwane obunobushushu obushushu bee-HPMC Polymers kunokuncedisa ekuqulunqweni kweemveliso ngeepropathi ezingaguqukiyo nezinqwenelekayo. Ke ngoko, ukufundwa kwe-HPMC Viscofity kubalulekile ukuqinisekisa ukusebenza kakuhle kwizicelo ezahlukeneyo kwigumbi lamayeza, ukutya kunye nemizi-mveliso ye-cosmetic.
