Hydroxypropyl methylcelculose (hpmc)Ngaba i-polymer eguquguqukayo isetyenziswe kumashishini anje ngamayeza, ukwakhiwa, i-cosmetics, ukutya kunye nokhathalelo lobuqu. Uhlobo lwe-HPMC ludlala indima ebalulekileyo ekumiseleni ukufaneleka kwayo kwizicelo ezahlukeneyo. I-viscofity ichukunyiswa bubunzima bemolekyuli, isidanga sokufaka kunye nokugxininisa. Ukuqonda amabakala afanelekileyo okufana kubalulekile ekukhetheni i-HPMC yasekunene kwiimfuno ezithile zeshishini.
Imilinganiselo ye-Viscosity
I-viscosity yase-Infochl®HPMC iqhele ukulinganiswa kwizisombululo ze-accources kusetyenziswa i-visarment okanye i-capillary. Iqondo lobushushu lovavanyo elisezantsi lingama-20 ° C, kwaye i-vickosity ibonakaliswe kwi-millipascal-imizuzwana (i-MPAF okanye i-CP, i-ntindipoise). Amabakala ohlukeneyo e-HPMC anezinto ezahlukeneyo zokundwendwela ngokuxhomekeka kwisicelo sabo.
Amabakala e-Viscosity kunye nezicelo zabo
Itheyibhile engezantsi ichaza amabanga aqhelekileyo e-HPMC kunye nezicelo ezifanayo:
| IBakala Lokubonisa (Mparo) | Uxinzelelo oluqhelekileyo (%) | Isicelo |
| I-5-100 | 2 | Iliso lamehlo, izongezelelo zokutya, ukunqunyanyiswa |
| I-100 ukuya kwi-400 | 2 | I-Tecwelt Coyints, Binders, Abomshes |
| I-400 - i-1,500 | 2 | I-Emosifiers, i-Lubinants, iinkqubo zokuhambisa iziyobisi |
| I-1,500-4,000 | 2 | Iiarhente zokubatha, iimveliso zononophelo lomntu |
| I-4,000 - 15,000 | 2 | Ulwakhiwo (ii-obedhesheves, iimveliso ezisekwe) |
| I-15,000 - 75,000 | 2 | Ukulawulwa kweSoftware yokukhutshwa kweziyobisi, ukukhula kwe-grouts |
| I-75,000 - 200,000 000 | 2 | I-Vidasity ephezulu, ukuqiniswa kokuqiniswa |
Izinto ezichaphazela i-viscofity
Izinto ezininzi zinefuthe kwi-viscosity ye-HPMC:
Ubunzima bemolekyuli:Ubunzima obuphezulu bemolekyuli bukhokelela ekunyukeni.
Inqanaba lokufaka endaweni:Umyinge we-hydroxypropy kunye namaqela e-methyl ichaphazela ukonakala kunye nohlobo lwe-viscosity.
I-Countration:Uxinzelelo luphumela kwi-viscosity enkulu.
Iqondo lokushisa:I-Viscosity inciphisa iqondo lobushushu esandayo.
Imvakalelo ye-PH:Izisombululo ze-HPMC ziyazinza ngaphakathi kwi-PH yoluhlu lwe-3-11 kodwa inokuhlanjwa ngaphandle kolu luhlu.
Ixabiso le-Shear:I-HPMC ibonakalisa iipropathi ezingenamva kwe-New-New-Newtonian, okuthetha ukumiswa kwe-vissity kuncitshiswa uxinzelelo lwe-Shear.
Ukuqwalaselwa kwesicelo
Amayeza:I-HPMC isetyenziswa kwiziko leziyobisi lokukhululwa elilawulwayo kunye ne-binder kwiitafile. Amabakala o-Viscosity ophantsi (100) I-MPAFS ithathelwa ingqalelo iingubo, ngelixa amabakala aphezulu (15,000+ +) asetyenziselwa ukwenziwa kokukhutshwa kwemali.
Ulwakhiwo:I-Nuinccel®HPMC isebenza njenge-amerile yokugcina amanzi kwaye inamathela kwiimveliso ezisekwe kwisamente. Amabakala aphezulu e-viscosity (ngaphezulu kwe-4,000 i-MPAFS ilungele ukuphucula ukusebenza kunye namandla achumileyo.
I-Cosmetics kunye noKhathalelo loMntu:Kwi-shampoos, i-lotions, kunye neekhrim, imisebenzi ye-HPMC njenge-thickener kunye ne-stabilizer. Amabakala e-Vidasity vissity (400-1500 mpas) anikele ibhalansi efanelekileyo phakathi kwepropathi kunye neepropathi zokuhamba.
Ishishini lokutya:Njengesongezelelo sokutya (E464), i-HPMC ixhasa ukuthungwa, uzinzo, kunye nokugcinwa komswakama. Amabakala obu-viscosity ophantsi (5-100 Mpas) aqinisekise ukusasazeka ngokufanelekileyo ngaphandle kokuthambisa kakhulu.
UkukhethaI-HPMCIbakala lokubonisa kuxhomekeke kwisicelo esicetywayo, kunye namabakala o-Viscosity esezantsi ofanelekileyo kwizisombululo ezifuna ukuqina okuncinci kunye namabakala aphezulu obu-viscosity ezisetyenzisiweyo kwiindawo ezinamathela ezomeleleyo kwaye azinzanga. Ulawulo lwe-viscosity olufanelekileyo luqinisekisa ukusebenza ngokukuko kwiindawo zamayeza, ukwakhiwa, ukutya kunye namashishini e-cosmetics. Ukuqonda izinto ekuphembeleleka kuVavasity kunceda ekusebenziseni ukusetyenziswa kwe-HPMC yezicelo ezahlukeneyo zeshishini.
