Ngaba i-HPMC 200000 viscosity ithathwa njenge-viscosity ephezulu?

Ewe, i-Hydroxypropyl Methylcellulose (HPMC) ene-viscosity ye-200,000 mPa·s (millipascal-seconds) ithathwa ngokuba ine-viscosity ephezulu. I-Viscosity ngumlinganiselo wokuxhathisa kolwelo ukuhamba, kwaye i-HPMC ene-viscosity ye-200,000 mPa·s iya kuba nokumelana okuphezulu okuhambayo xa kuthelekiswa namabanga asezantsi e-viscosity.

I-HPMC ifumaneka kuluhlu olubanzi lwamabakala e-viscosity, aqhele ukuqala ukusuka kwi-5,000 mPa·s ukuya kuma-200,000 mPa·s okanye ngaphezulu. Ibakala elithile le-viscosity elifunekayo kwisicelo esithile lixhomekeke kwizinto ezifana neempawu ezifunwayo ze-rheological, indlela yesicelo, iimeko ze-substrate, kunye neemfuno zokusebenza.

Ngokubanzi, amabakala aphezulu e-viscosity ye-HPMC ahlala esetyenziswa kwizicelo apho ukuqina okungqindilili okanye ugcino olukhulu lwamanzi lufunwayo, njengee-agent ezityebisayo, iingubo, izinto zokuncamathelisa, kunye neemveliso ezisekwe kwisamente. La manqaku aphezulu e-viscosity anikezela ukuxhathisa kwe-sag engcono, ukuphuculwa kokusebenza, kunye nokusebenza okuphuculweyo kwizicelo ezithe nkqo okanye ezingaphezulu.

Kubalulekile ukuqaphela ukuba i-viscosity iyodwa ayinakumisela ngokupheleleyo ukufaneleka kwe-HPMC kwisicelo esithile, kunye nezinye izinto ezifana nokusabalalisa ubungakanani besuntswana, ubunyulu, kunye neempawu zekhemikhali nazo zinokudlala indima. Kubalulekile ukuqwalasela yonke imiba efanelekileyo kwaye udibane nenkcazo yemveliso kunye namaphepha edatha yobugcisa xa ukhetha ibakala elifanelekileyo le-viscosity ye-HPMC yokwenziwa okanye ukusetyenziswa okuthile.
