Mekhoa e tloaelehileng le e bonolo ea ho khetholla boleng ba selulose ea HPMC

Mekhoa e tloaelehileng le e bonolo ea ho khetholla boleng ba selulose ea HPMC:

1. Boemo ba pono ea selulose e hloekileng ea HPMC ke fluffy, 'me bongata bo bongata bo nyane, bo nang le mefuta e mengata ea 0.3-0.4g / ml; Adulterated HPMC cellulose e na le mokelikeli o betere le boima ba letsoho bo boima, bo fapaneng haholo le ponahalo ea lihlahisoa tsa 'nete.

2. Bosoeu ba selulose e hloekileng ea HPMC e ntle, ho bolelang hore thepa e tala e sebelisoang tlhahisong e hloekile 'me karabelo e nepahetse ntle le litšila. Ha ho bapisoa le lihlahisoa tsa ether tsa cellulose tsa kantle ho naha, ho ka bonoa hore bosoeu ba sehlahisoa se setle sa cellulose ether bo lula bo le betere ho feta ba lihlahisoa tsa mofuta oa bobeli oa lehae.

3. Tharollo e hloekileng ea HPMC cellulose aqueous e hlakile, e nang le phetiso e phahameng ea leseli, le sekhahla sa ho boloka metsi ≥ 97%; Tharollo ea metsi a selulose ea HPMC e ferekantsoeng e senyehile, 'me sekhahla sa ho boloka metsi se thata ho fihlela litlhoko. Ho fetisoa ha leseli la tharollo ea metsi ho molemo, e leng se bontšang hore sehlahisoa se na le lintho tse fokolang tse sa tsitsang le lintho tse phahameng tsa metsoako e sebetsang.

4. Selulose e hloekileng ea HPMC ha ea lokela ho fofonela ammonia, starch le joala; Selulose ea HPMC e kentsoeng hangata e ka fofonela mefuta eohle ea litatso. Esita le haeba e sa latsoehe, e tla ikutloa e le boima.

5. HPMC e hloekileng ea selulose phofo e na le fibrous tlas'a microscope kapa khalase e hōlisang; Selulose ea HPMC e silafalitsoeng e ka bonoa e le granular solid kapa kristale ka tlas'a microscope kapa khalase e holisang.

6. Mokhoa o bonolo oa tlhahlobo bakeng sa litaba tsa molora oa cellulose ether: boima ba ligrama tse le 'ngoe ho isa ho tse peli tsa cellulose ether, ho e hotetsa ka leseli, lekanya masala a molora a siiloeng ke ho chesoa ha selulose ether,' me ha molora o setseng / selulose ether ke ≥ 5 %, boleng ba cellulose ether ha e le hantle ha bo tšoanelehe. (ka linako tse ling ho na le liphoso mokhoeng ona. Ea pele, moetsi o ile a kopanya lihlahisoa tse loketseng bareki ba itseng pele ba tloha fekthering; ea bobeli, baemeli kapa bahlahisi ba ile ba eketsa lintho tse tukang tse nang le molora o fokolang ha li senya)

7. Lifeme tse ling le malapa a sebelisa chelete e nyenyane ea C cellulose e kopantsoeng le hydroxypropyl methyl cellulose ether, 'me ha tharollo e nang le metsi ea C cellulose e kopana le tin, silevera, aluminium, lead, tšepe, koporo le lisebelisoa tse ling tse boima, ho tla etsahala karabelo ea pula; Ha c-cellulose aqueous solution e kopana le calcium, magnesium le letsoai, e ke ke ea hlahisa pula, empa e tla fokotsa viscosity ea c-cellulose aqueous solution.

8. Haeba maemo a lumela, leka ka ho toba viscosity ea tharollo ea metsi ea cellulose ether 'me u bapise sekhahla sa ho boloka metsi sa seretse se tlaase sa cellulose ether.

Joaloka moetsi ea hloahloa oa cellulose ether, Youngcel cellulose e tla fa bareki ka pelo eohle lihlahisoa le litšebeletso tsa boleng bo holimo
