Yintoni i-viscosity ye-hydroxypropyl methylceltulose?

Hydroxypropyl methylcellulose (HPMC) is a thickener, gelling agent and film former commonly used in the pharmaceutical, food, cosmetic and building materials industries. Uhlobo lwayo lwenye yeeparamitha ezibalulekileyo ezichaphazela intsebenzo yayo, eqhele ukuhluka ngokwezinto ezinje ngoxinzelelo lwesisombululo, uhlobo lwe-solvent, ubunzima kunye nemolekyuli ye-HPMC.

Ixabiso le-viscosity le-HPMC libhekisa kulwelo lwesicombululo phantsi kweemeko ezithile, idla ngokuboniswa kwi-MPAFS (imizuzwana)). Kwimeko ye-viscosity ye-HPMC, uxinzelelo oluqhelekileyo yi-2% okanye i-4% yesisombululo, kunye neqondo lobushushu lingama-20 ° C okanye i-25 ° C. Kuxhomekeka kuhlobo lwemveliso kunye nemveliso, i-viscosity ye-HPMC inokuvela kumakhulu ambalwa e-MPAF ukuya kumawaka ambalwa eMparo.

Ezi zinto zilandelayo zezona zinto ziphambili ezichaphazela i-viscofity yesisombululo se-HPMC:

Ubunzima bemolekyuli: bukhulu obukhulu bemolekyuli ye-HPMC, ukuphakama kwalo. I-HPMC enemigangatho ephezulu yemolekyuli inokwenza unxibelelwano olungakumbi kwisisombululo, ngoko ke libonisa i-viscofity ephezulu.

I-HYDROXYPOPLY NOPHANDO LOKUGQIBELA Ukunyuka kokufakwa endaweni ye-hydroxypropy kunokuphucula ngokufanelekileyo ukunyibilisela i-HPMC, ngelixa ubuchwephesha bundisa i-viscofity yayo.

Ugxininiso lwesisombululo: Ukuxinana kwesisombululo se-HPMC kuchaphazela ngqo i-viscofity yayo. Uphando oluphezulu, olukhulu kakhulu. Ngokubanzi, izisombululo ezinoxinzelelo phakathi kwe-2% ne-5% ziqhelekileyo, kwaye i-viscosity yezisombululo ezixineneyo ziya kuphakama.

I-Solvent: I-HPMC iqukethe kakuhle emanzini, ngoko ke uVenkile wayo uhlala uvavanywa ngokusekwe kwizisombululo ze-ACOT. Nangona kunjalo, iintlobo ezahlukeneyo zezinyibiliki zinokuchaphazela ukuswela kunye nokubonisa.

Iqondo lokushisa: Iqondo lokushisa linefuthe elibonakalayo kuhlobo lwe-HPMC. Ngokubanzi, ukwanda kwamaqondo obushushu kuya kukhokelela ekunciphiseni kwesisombululo kuba amaqondo obushushu aphezulu ayakukhawulezisa intshukumo yemolekyuli kwaye anyuse ulwelo lwesisombululo.

I-HPMC Viscosity ihlala isetyenziswa kwezi nkalo zilandelayo:

Intsimi yamachiza: isetyenziswa njenge-arhente ekhuselekileyo yeziyobisi, ithebhulethi, kunye necandelo leegobolondo zecapsule. Inokuqinisekisa ukukhululwa kweziyobisi kwiziyobisi ngokulawula uVeksisity.

Ishishini lokutya: Isetyenziswe njengearhente ye-tickener kunye ne-geling, inokuphucula intanda kunye nokuthungwa kokutya, njenge-ice cream, ijeli, ipipi, njl njl.

Ishishini lokwakha: isetyenziswe njengearhente yokugcina amanzi kunye nokugcina amanzi ekwakhiweni kwezinto ezinjengesamente kunye nodaka ukuphucula ukusebenza kunye nokusebenza kwentsebenzo.

I-Cosmetic Ishishini: Isetyenziswe kwiimveliso ezinjengeekhrim, iingcibi zobuso, izithunzi zemehlo, njl njl.

Xa ukhetha imveliso ye-HPMC efanelekileyo, kubalulekile ukuba uqonde iimpawu zayo zokufakwa kwezinto, ngakumbi iimfuno zolwelo kunye nokuzinza kwizicelo ezahlukeneyo. Ukuba kukho imfuneko yexabiso le-viscofity elithile le-HPMC ethile, ungabhekisa kulwazi olufanelekileyo kwimveliso yemveliso okanye uyivavanye ngesixhobo sokulinganisa.
