Titiani Cellullose He tohunga nui ki te rangahau, whanaketanga, whakaputa me te whakatairanga whakatairanga o te hydroxypropyl methyl cellulose ppmc. Ko te Mahana o te HPMC Hydroxypropyl Cellulose te kaupapa nui rawa atu mo nga kaihanga me nga kaiwhakamahi. I konei ka taea e matou te hydroxypropyl methyl cellulose e whakaatu ana i tetahi whakakitenga taipitopito, kei te tumanako ahau kia pai ake te awhina.
Te whakatau i te pokekore o te hpmc hpmc hpmc hydroxypropyl methyl cellulose
Te parau tumu
Hydroxypropyl methyl cellulose hpmc he koretake i te 80% etanol. I muri i te rewa me te horoi mo nga wa maha, 80% ethanol kua whakakorea i roto i te tauira ka wehea, ka tangohia kia whiwhi i te hydroxypropy parakore.
Rwhaiwhera
Ki te kore e kii, ko nga mea noa e whakapumautia ana he wai parakore, he waikore ranei, he wai ranei, he wai pai ranei ka whakamahia i roto i te tātaritanga.
95% etanol (GB / T 679).
Ethanol, 80% otinga, waimeha 95% etanol (e.2.1) 840ml me te wai ki te 1l.
BMI (GB / T 12591).
Te taputapu
Tohutoro taiwhanga noa
Ko te Stirrer Whakatinana AGNETIC, te tere o te rod mo te 3.5cm.
Filtration Srucible, 40ml, Aperture 4.5μm ~ 9μm.
Te rihi paraihe karaihe, φ10cm, Central Ble.
Pia, 400ml.
Kaukau pāmahana wai.
Ko te oumu, ka taea te whakahaere i te pāmahana i te 105 ℃ ± 2 ℃.
Te hōtaka
Kia tika te taumaha o te tauira 3G (tika ki te 0.001g) ki te riihi i te riihi, ka whakaurua te tere o te hau, me te pupuri i te pāmahana. 65 ℃. Whakaoho mo te 10 meneti.
Kati te whakaohooho, tuu i te ipurau i roto i te pati wai totika o te 60 ~ 65 ℃, tu tonu ki te whakatau i nga take kore, ka riringi ki te wai totika ka taea te whakamahi i te kiriata whakahekeheke tonu.
Tāpirihia te 150mL 80% etanol i te 60 ℃ ~ 65 ℃ ki te kokonga o runga, ka horoi i te kirika, ka horoia nga mea o te riihi. Me whakamahi te kohu i te wa o tenei mahinga me te whakamaroke o te keke kia karohia. Mena ka pahemo nga matūriki ki te tātari, me heke iho te kohurutanga.
FAKATOKANGA: Me matua whakarite kia pai te konutai i te tauira i te 80% etanol. Mena e tika ana, 0.1Mol / L Rongoānuku hiriwa nitrate me te 6mol / L te waikawa nitric ka taea te whakamahi mehemea kei roto i te filtrate te katote chlaterate.
I te pāmahana rūma, i horoia nga tuhinga e rua me te 95% etanol i te 50ml, ka mutu me te ethyl mi20ml mo te horoi tuarua. Ko te waa whakakapinga kia kaua e roa. I whakanohoia te Gracible ki roto i te ipurau ka mahana i runga i te pati kaukau kia kore ai e kitea e te ethyl mi ra kakara.
FAKATOKANGA: Te horoi me te ethyl mi me te tika ki te tango i te etanol mai i te taonga ngoikore. Mena kaore e tino tangohia katoatia te Etanol i mua i te whakamaroke o te oumu, kaore e taea te tango i te waa o te umu.
I whakanohohia te riipene me te piahi ki te oumu i te 105 ℃ ℃ 2 ℃ mo te whakamaroke mo te 2h, ka nekehia atu ki te whakamaroke kia kaua e neke atu i te 0.003g. I roto i te take o te pikinga papatipu i te ra maroke 1h, ka kaha te papatipu kua kitea.
Ko nga hua kua tohua
Ko te Mahana o te HPMC HydroxyPropyl Cellulose i kiia ko te haangai papatipu P, a ko te uara i puta he%
M1 - ropu o te mea maroke maroke, i roto i te karamu (g);
M0 - papatipu o te waahanga whakamatautau, i roto i te karamu (g);
W0 - te makuku me te kiko o te tauira,%.
Ko te uara o te uara o nga mehua rite e rua ka whakaitihia ki tetahi tohu whakataurite rite te hua inenga.
Ptuku
Ko te rereketanga tino i waenga i nga mehua motuhake i puta i raro i nga tikanga tuuturu kaore i te nui ake i te 0.3%, na te nui ake i te 0.3% kaore e neke atu i te 5%.
