HydroxyPropyl methylcellose (HPMC) ishandirwi yakashandiswa-mvura-soluble polymer cellulose inoshandiswa zvakanyanya mukuvakwa, mishonga, chikafu, chejasi uye mamwe minda uye mamwe minda uye mamwe minda uye mamwe minda. HPMC ine yakanakira kudzokorora kwemvura, kuremedza, firimu-kugadzira uye kugadzikana midziyo, uye kugadzikana kwayo mumhinduro ine kukosha kwakakosha pakuchengeta kwemvura.
1. Nheyo dzeBhaibheri dzeHPMC Kuchengeta kwemvura
HPMC inoumba matatu-dimensional network network network uye yekuyambuka muviri pakati pemanyorerwe emanyorerwo mumvura mhinduro, iyo inogona kunyatso kutora uye kuchengetedza kunyorova. Kuchengetwa kwemvura kwayo kunonyanya kuratidzwa mune zvinotevera zvinhu:
Chikuru chemuviri: Iyo hydroxyl mapoka paHPMC molecular cheni inogona kuumba hydrogen zvisungo, bata nemamolekyudhi emvura, uye kutora uye chengetedza zvinyoro.
Viscosity mhedzisiro: Hpmc inowedzera iyo yokuvonekwa kwemhinduro uye inoderedza iyo fluiliity yemvura, nekudaro ichidzora kutsika kwemvura uye kupinda kwemvura.
Firimu rinogadzira kugona: HPMC inogona kuumba yunifomu yekudzivirira yefirimu yekuvharidzira kubhururuka kwemunyoro.
2. Mhedzisiro yekusangana pamusoro pekuchengetwa kwemvura kweHPMC
Kuchengetwa kwemvura kweHPMC kwakanyatsoenderana neyakaonana nemhinduro, uye kwakasiyana kwemvura kuchengetwa kwakaratidzirwa pane zvakasiyana pakatarisana.
2.1 Yakadzika Sportration Range
Pazasi pakatarisana (kazhinji pazasi 0.1%), HPMC mamorekuru haaumbe yakakwana matatu-dimensional network mumvura. Kunyangwe paine imwe yemvura yekunyora mvura uye yakakora simba, kuchengetwa kwemvura kunogumira nekuda kwekushaiwa simba kwekudyidzana. Panguva ino, kuchengetwa kwemvura kwemvura kunonyanya kuenderana neyekushambadzira kwemanyorero ematehwe emanyorerwo.
2.2 pakati peSveni Yekusangana Range
Kana iko kusungwa kweHPMC kunowedzera kusvika pakati pe0.1% uye 2%, iyo Intermolecular Interniclions inovandudzwa uye yakagadzikana matatu-dimensional network network network yakaumbwa. Panguva ino, visikopa yemhinduro inowedzera zvakanyanya, iyo inosimudzira kugona kwemvura uye nekuchengetwa kwemvura. HPMC mamorekuru anoumba denser network kuburikidza nekuyambuka muviri-kuunganidza, zvinobudirira kuderedza kuyerera uye kubuda kwemvura. Naizvozvo, kuchengetwa kwemvura kweHPMC kwakanyatsogadziriswa mune yepakati yekusungwa renji.
2.3 Yakanyanya Kusimbisa Range
Pakunyika yakakwirira (kazhinji yakakura kupfuura 2%), HPMC mamorekuru inoumba yakanyanya kujairika network network chimiro, uye mhinduro inoratidzira viscosity yakakwira uye ichinonoka kusvika kune gel State. Mune ino mamiriro, HPMC inokwanisa kutora uye kuchengetedza kunyorova kusvika mukurusa kwakanyanya. Kuwedzeredza kwepamusoro kweHPMC kwakanyanya kuwedzeredza mvura yekuchengetedza mvura uye inoderedza huwandu hwemvura, uchibvumira kuratidzira kuita kwakanaka mukuita kwakakwirira kwemvura kunoda kuchengetwa kwemvura.
3. Inoshanda application yeHPMC yekuvhara uye kuchengetwa kwemvura
3.1 Munda wekuvaka
Muchikepe chivakwa, HPMC inovandudza kuita kwekuvaka nekuvandudza kuchengetedza kwemvura, kuderedza kurasikirwa kwemvura panguva yekuvaka, kuendesa nguva yekutanga yevhu. HPMC inowanzo shandiswa mumutumbi pakukwirira kwe1,1% kusvika 1.0%, huwandu hunobudirira hunoenderana nekuchengetwa kwemvura uye kushandira viscossity.
3.2 mishonga yemisheni
Mumapiritsi emishonga yemishonga, HPMC inoshandiswa seyakagadzirirwa kuburitswa uye piritsi bhasiketi kuti uwane zvakaringana-kuburitsa mishonga nekudzora huwandu hwemvura. Iko kusunganidzwa kweHPMC mumishonga inowanzoitika kubva pa1% kusvika ku5%, iyo inopa kuchengetwa kwemvura yakakwana uye kubatana kuti uve nechokwadi chekuvimbika uye kusunungurwa kwezvinodhaka kubva piritsi.
3.3 Chikafu Chinondo
Muindasitiri yekudya, HPMC inoshandiswa seanotenda uye stabilizer kuti uvandudze kuyamwisa uye kuchengetwa kwemvura kwezvigadzirwa. Semuenzaniso, kuwedzera HPMC kune chingwa kunogona kuvandudza kuchengetwa kwemvura uye kupfava kwehupfu, kazhinji pakutarisisa pakati pe2,2% uye 1%.

Optimizing plancarnation yekuchengetwa kwemvura yakakwana inoda kufunga nezvezvinhu zvakadai sekutarisirwa kwechinangwa chekushandisa, kuitira kuti kuve nechokwadi chekuchengetwa kwemvura pasina kukanganisa maitiro ekugadzirisa uye zvimwe zvinhu zvemhinduro.
Iko kusangana kweHPMC ine kukosha kwakanyanya pakuchengeta kwemvura kwemhinduro. Pakukona kwakaderera, kuchengetwa kwemvura kunogumira; Pazvivakwa pakati, chimiro chakagadzikana network chinoumbwa kuti uvandudze kuchengetwa kwemvura; Pakumanikidzwa kwakanyanya, iyo yakakwira mvura yekuchengetedza inowanikwa. Minda yakasarudzika yekushandisa ine zvakasiyana zvinodikanwa zveHPMC yekushambadzira, iyo inofanirwa kugadziriswa zvine musoro zvichienderana nezvaanoda kuti uwane chiyero pakati pekuchengetedza kwemvura nekugadzirisa.
