ASH zvemukati chiratidzo chakakosha chehydroxypruppropyl methylcellose. Vatengi vazhinji vanowanzo bvunza pavanonzwisisa hydroxyprupyl methylcellose: Chii chinonzi omh kukosha? Hydroxyprupropyl methylcellose ine chidiki chidiki zvirimo zvinoreva zvakanyanyisa kuchena; Cellulose ine yakakura kunge hombe zvirimo zvinoreva kuti pane zvakawanda zvakasvibiswa mazviri, izvo zvinokanganisa kushandiswa kana kuwedzera huwandu hwekuwedzera. Kana vatengi vakasarudza hydroxyprupyl methylcellose, vanowanzovhenekera zvakananga mamwe mheremhondi nemoto uye uzvipise kuti vaedze izvo zvemasero. Asi iyi nzira yekuona haina ruzivo rwesainzi zvakanyanya, nekuti vazhinji vagadziri vanowedzera maruva anowedzera kune cellulose. Pamusoro, iyo cellulose ine diki diki patsva mushure mekupisa, asi mukuita, iyo yekuchengetwa kwemvura yehydroxyprishlcellose haina kunaka.
Saka isu tinofanira kunyatsoona sei iyo hyk yezvinyorwa yehydroxyprupyl methylcellose? Iyo chaiyo yekuona nzira ndeye kushandisa muffle choto kuti uone.
Chishandiso chekuongorora chiyero, tembiricha yakanyanya muffle muchoto, choto yemagetsi.
Kuedza maitiro:
1) Kutanga, isa 30ml porcelain yakakwira mune yakakwirira-temble muffle muffle muffle muffle muffle muffle Fire. kunze kweanowanzoitika uye kuifambisa kune desiccator kuti itonhore (20 ~ 30) min, kuyera.
2) kuyeuka 1.0 g yehydroxypruppropyl methylcellosepane chiyero chekuongorora, isa sampuro yakacheneswa mune chockulible, wozoisa iyo inochengeterwa iyo sampula yechira chemagetsi, inotonhorera yekupisa, 0.5-1.0) ml, uye isa iyo pane magetsi emagetsi yakazara carbonization. Wobva waenda kune yakakwira tembiricha muffle muffle muffle Fire, 500 ~ 600) Kuti utonhore (20 ~ 30) min, uye wobva wayerwa pane chiyero chekuongorora.
Currenclation Ignition yakasara inoverengwa zvinoenderana formula (3):
M2-M1
Kusaririra zvakasara (%) =
m
Mune formula: M1 - huwandu hweisina chinhu chisina chinhu, mu g;
M2 - Misa yeiyo yakasara uye inochengera, mu g;
m - huwandu hwemuenzaniso, mu g.
