I-1. I-HPMC yahlulahlulwe yanguhlobo lwethutyana kunye nohlobo olukhawulezayo.
I-HPMC ye-HPMC yoThengiso lwe-HPMMC inonobumba s njengesimamva I-GYSOxal kufuneka yongezwe ngexesha lenkqubo yemveliso.
I-HPMC yokusasaza i-HPMC I-Supection Pay-Sheating ayongeziyo naziphi na iileta, ezinje nge "100000" lithetha "i-100000-viscosity ngokukhawuleza-ukusasaza i-HPMC".
2. Nge okanye ngaphandle okanye ngaphandle kwe-S, iimpawu zahlukile
Ukusasaza ngokukhawuleza i-HPMC isasaza ngokukhawuleza emanzini abandayo kwaye inyamalale emanzini. Ulwelo alunamfanekiso okwiphepha elithile kuba i-HPMC ichithwa njengamanzi kwaye ayichithwanga nyani. Emva kwemizuzu emibini, i-viscosity ye-ulwelo ngokuthe ngcembe inyuka, yenza ulwelo olubonakalayo lwe-viscous. I-colloid ye-colloid.
I-HPMC ye-HPMC ingasasazeka ngokukhawuleza emanzini ashushu kuma-70 ° C. Xa iqondo lobushushu liye kwehla kubushushu obuthile, i-vickosity ivela kancinci de i-vicous engabonakaliyo yenziwa.
3. Nge okanye ngaphandle kwe-S, injongo yahlukile
I-HPMC ye-HPMC inokusetyenziswa kuphela kwi-pody powder nodaka. Kwibhotile yolwelo, iipeyinti kunye nezinto zokucoca, i-clumps zinokwenzeka kwaye zingasebenzi.
Ukusasaza ngokukhawuleza i-HPMC kunoluhlu olubanzi lwezicelo. Ingasetyenziselwa umgubo ongcolileyo, udaka, i-glue engamanzi, ipeyinti, kunye nokucoca izinto ngaphandle kokuphikisana.
indlela yokuphelisa
1. Thatha inani elifunekayo lamanzi ashushu, yibeke kwisitya kwaye usitshise ngaphezulu kwe-80 ℃, emva koko udibanise le mveliso ngokukhuthaza kancinci. I-seluplose idadayo kumphezulu wamanzi ekuqaleni, kodwa ngokuthe ngcembe zasasazeka zenza iyunifomu efanayo. Phola isisombululo ngelixa ushukumisa.
2. Okanye ubushushu 1/3 okanye i-2/3 yamanzi ashushu ngaphezulu kwe-85 ° C, ukongeza isellulose ukufumana amanzi ashushu, emva koko wongeze ngokuqhubekayo umxube ophumeleleyo.
I-3. I-Sellulose inobukhulu obuhle be-mesh kwaye bukhona njengamasuntswana amancinci amancinci kumgubo onomdla. Iyayinyibilikisa ngokukhawuleza xa ityhilwe emanzini ukwenza i-viscofity efunekayo.
4. Yongeza isellulose kancinci kwaye ngokulinganayo kubushushu begumbi, ishukumisa ngokuqhubekayo kude kube sekufuphi isisombululo esicacileyo.
Zeziphi izinto ezichaphazela ukugcinwa kwamanzi kwe-hydroxlypropyl methylcelcelcelgulose?
Ukugcinwa kwamanzi kwe-hydroxypropyl methylcelcelgalose i-HPMC Iimveliso ze-HPMC ngokwayo zihlala zichaphazeleka kwezi zinto zilandelayo:
1
I-hpmcy ye-HPMC ephindaphindiweyo ye-HPMC kunye nee-hydroxyproposty zamaqela azisasazwa kwaye zigcinwe kakhulu amanzi.
I-2. I-Telupelose Ether HPMC yeqondo lokushisa i-gel
Ukuphakama kweqondo lobushushu le-gene ye-thermal and rimer iqondo lokugcina amanzi; Kwelinye icala, ezantsi inqanaba lokugcina amanzi.
I-3. I-Viscosity ye-Selese-I-EREMC
Xa i-vickosity ye-HPMC inyuka, iqondo lokugcina amanzi liyanda; Xa i-viscosity ifikelela kwinqanaba elithile, ukwanda kwemilinganiselo yokugcina amanzi ethambile.
I-SelerUse Ether HPMC yongeno
Inqanaba elikhulu le-iler i-erlulose i-HPMC yongezwa, iphakamile kwinqanaba lokugcina amanzi kunye nokulungileyo komsebenzi wokugcinwa kwamanzi.
Kuluhlu lwe-0.25-0.6%, iqondo lokugcina amanzi linyusa ngokukhawuleza njengoko inani elongeyo elonyukayo; Xa ukongezwa konyuso lonyuka, ukunyusa imeko yeqondo lokugcina amanzi liyacothisa.
