TIANTAI Cellelose Kambani Inoshamisa mukutsvagisa, kusimudzira, kugadzirwa uye kutengesa kukwidziridzwa kwehydroxypropropropropyl methelose hpmc zvigadzirwa. Kuchena kweHPMC hydroxypropropyl methyl cellelose ndiyo yakanyanya kujairika chigadzirwa chinyorwa chetsoka nevashandisi. Pano isu hydroxypruppropyl methyl cell vemugadziri kupa chinyorwa chedzidzo, ndinovimba kuverenga kubatsira.
Kutsunga kwekuchena kweHPMC hydroxypropropropyl methyl cellulose
Nheyo yacho
Hydroxyprupyl methyl cellel cellulose hpmc is is erxuble mu80% ethanol. Mushure mekunyungudika nekushambidza kakawanda, 80% ethanol dissolved mumuenzaniso wakaparadzaniswa uye kubviswa kuti uwane pure hydroxproproproproproproproproproproproprol cell
REAGENT
Kunze kwekunge zvataurwa neimwe nzira, chete reagents inosimbiswa kuve nekuongororwa kwakachena uye kwakadzikira kana kuti madhiri emvura kana mvura yekuchena yakafanana ichashandiswa mukuongorora.
95% ethanol (GB / T 679).
Ethanol, 80% Solution, Dilute 95% ethanol (e.2.1) 840ml nemvura kusvika 1l.

Chiridzwa
Zviridzwa Zvakawanda Zviridzwa
Magineti ekudziya anokurudzira, kusimudzira tsvimbo kureba nezve 3.5cm.
Filtration inowanzoitika, 40ml, aperuture 4.5μm ~ 9μm.
Girazi nzvimbo yekuvhara, φ10cm, central gomba.
Beaker, 400ml.
Nguva dzose yekupisa mvura yekugezera.
Oveni, inogona kudzora tembiricha pa105 ℃± 2 ℃.
Chirongwa
Right rinorema sampuli 65 ℃. Kumutsa kwemaminetsi gumi.
STOP kumutsa, isa beaker mune yekudziya kwemvura yekugezera ye60
Wedzera 150ml 80% ethanol pa 60 ℃ ℃ ℃ ℃ ℃ ℃ To beakering nekuvhunduka, uye gwai Kuyamwa kunofanirwa kushandiswa panguva yekuvhiya uku uye kuoma kwekeke kunofanirwa kudzivirirwa. Kana zvimedu zvichipfuura nefaira, suction inofanira kuderedzwa.
Ongorora: Zvinofanira kuve nechokwadi chekuti sodium chloride mumuenzaniso wakashambidzwa zvachose ne80% ethanol. Kana zvichidikanwa, 0.1mol / l sirivheri nitrate solution uye 6mol / l nitric acid inogona kushandiswa kutarisa kana iyo filtrate ine chloriz ions.
Pamhepo tembiricha, zvirimo zvinokonzeresa zvakamiswa kaviri ne 95% ethanol pa50ml, uye pakupedzisira neTETHYL mi20ml yekushambidza kwechipiri. Iyo nguva yefaira haifanire kunge yakareba. Iyo inocheka yakaiswa mumubheji uye kupisa paSteam Bathre kusvika pasina Ethyl mi odyawiwiwa akawanikwa.
Ongorora: Kushambidza neTETHYL MI kunokosha kuti ubvise zvachose ethanol kubva kune insolubort chinhu. Kana ethanol isina kubviswa zvachose usati waoma ovening, kubviswa kwakazara hakugone kuomesa oven.
Iyo inowanzoitika uye beaker yakaiswa muvheni pa105 ℃± 2 Kana kuri kuwedzera kwakawanda mukati me1h kuoma, kuwanda kwakachengetwa kucherechedzwa kuchakundikana.
Mhedzisiro Yakaverengerwa
Kuchena kweHPMC HydroxyPropropyl Methyl Cellelose kwakaverengerwa seMisangano Misa P, uye kukosha kwakaratidza se%
M1 - Misa yeakaomeswa insoluble nyaya, mune magiramu (g);
M0 - Misa yeiyo bvunzo chikamu, mune magiramu (g);
W0 - kunyorova uye kusiririsa zvemukati kweiyo sampuli,%.
Iyo arithmetic zvinoreva kukosha kwezviyero zviviri zvakafanana zvinoderedzwa kune imwe cormal point sezvo chiyero chakaenzana.
Pdzokorora
Musiyano Wese pakati pezvikamu zviviri zvakazvimirira zvakawanikwa mumamiriro ezvinhu ekudzokorora hazvisi zvakakura kupfuura 0.3%, zvakapihwa zvakakura kupfuura 0,3% hazvipfuure 5%.
