HydroxyPropyl methylcellose (HPMC) ndeye semi-synthetic, inert, isina chepfu mvura-yekunyora-soluble polymer inoshandiswa mumaindasitiri, chikafu, cosmetics uye zvekuvakisa uye zvekuvakisa. Ukama pakati pehukama hwayo hunorema uye viscosity zvine hunyanzvi hwakakosha pakuita kwayo mukushandisa kwakasiyana siyana.
1. Solubility uye firimu-kugadzira zvivakwa
Iyo viscosity yeHPMC yakanangana nayo inobata solubility mumvura. HPMC ine yakadzika viscosity inogona kunyungudika mumvura nekukurumidza uye gadzira mhinduro yakajeka uye yakajeka yekunyorera inoda kukurumidza kuparadzaniswa, senge zvinwiwa zvinokurumidza kana kuti zvinokonzeresa. HPMC ine yakakwira viscosity inoda nguva yekunyora kwenguva refu, asi inogona kupa godo riri nani uye simba kana rakakodzera firimu, saka firimu retsiva uye seyakagadzirirwa matsuru mukugadzirira-matsvina ekusunungurwa-gadziriro dzekusunungura.
2. Kugadzikana uye kuderedza
HPMC ine yakakwira viscosity kazhinji ine simba rakasimba uye kudedera. Semuenzaniso, kana ichishandiswa seyakajaira seyement kana zvigadzirwa zveGypsum muzvivakwa zveHPMC zvinogona kudzoreredza kuchengetwa zvakanyanya nemvura yayo uye kuendesa nguva yekuvaka uye kuderedza kupaza. Muindasitiri yechechi, yakakwira-viscosity hpmc inoshandiswa kudzora iyo inodhaka yekuburitsa. Yake yakakwirira yekudyira inobvumira mushonga kuti usunungurwe zvishoma nezvishoma mumuviri uye unovandudza bhizimusi remushonga.
3. Kumiswa uye emulsization
Shanduko muViscosity zvakare inokanganisa iyo kumiswa kweiyo hpmc. Nekuda kweiyo pfupi pfupi molecular ketani, yakaderera-viscosity hpmc yakakodzera kushandiswa seyekumirisa mumiriri. Zvinogona kunyatsoisa kumisa zvinhu zvisingabvumirwe mumishonga yemvura uye kudzivirira kufungidzira. HPMC ine yepamusoro viscosity inogona kuumba yakasimba network network mamiriro nekuda kweiyo nguva refu molecular cheni, saka inoita kuti ive nani mukugadzikana kwemitsetse uye kumiswa uye kunogona kuramba kufanana kwenguva yakareba.
4. Rheology uye mashandiro ezvivakwa
Iyo yeReological Properties yeHPMC iri zvakare yakakosha chikamu chakakanganiswa neViscosity. Low-viscosity HPMC Solutions Exhibit iri nani fluidity, zviri nyore kupuruzira uye kushandisa, uye kazhinji inoshandiswa mune zvigadzirwa zveganda uye pendi. Iyo yakakwira-viscosity hpmc solution inozvibata seyisiri-Newtonian fluid uye ine shear-yakaonda hunhu. Hunhu uhwu hunoita kuti huwedzere-viscosity hpmc zviri nyore kubata pasi pemamiriro ekunze akareba, nepo kugarira visikopo pasi pemamiriro ezvinhu, nekukasira kugadzirwa kwefirimu uye kugadzikana kwechigadzirwa.

Pfekface Rwiyo rwezvinodhaka.
Chikafu munda: In Instant Bewges, yakaderera-viscosity HPMC inogona kunyungudika nekukurumidza pasina kudzima; Muzvigadzirwa zvakabikwa, High-viscosity HPMC dzinogona kuvandudza mvura ichibata mukana weupfu uye nekuwedzera kuravira uye zvinonyungudza zvigadzirwa zvezvigadzirwa zvakabikwa.
Munda wekuvaka: MuPutties uye hukuru, dzakaderera-viscosity HPMC inofambisa kuvaka uye inovandudza kushanda zvakanaka; Nepo High-viscosity Hpmc inowedzera ukobvu uye SAG kuramba kuungana.
Iyo viscosity yeHPMC ndeye kiyi paramende inosarudzira kuita kwayo mukushandisa. Yakadzika viscosity HPMC inowanzo shandiswa kune iyo Fast Dissolution uye kuyerera inodiwa, nepo High Viscosity HPMC inonyanya kubatsira mukushandisa yakakwirira yekudyidzana, yakanaka firimu kugadzirwa uye kugadzikana. Naizvozvo, kusarudza HPMC neiyo viscosity yakakodzera inokosha kuti ishandise mashandiro aro muminda dzakasiyana siyana.
