Mushure mekutengesa sevhisi: Tichatevera mhedzisiro yevatengi yekuyedza, uye kana paine dambudziko, tichazvitarisa panzvimbo.
Raw zvinhu kuongorora
Kuti tive nechokwadi chemhando yezvigadzirwa, isu tinoita zvakanyanya kuomeswa kwezvakatsikiswa, zvinoenderana neChina nyika zviyero.
Plasticizer kuyedza
Mushure mokunge batch imwe neimwe yasvika, ingangoita 500ml sampuro inotorwa kuti iite muyedzo.
2.Kutaridzika bvunzo: isina kuchena uye yakajeka, mvura sampuro mhinduro, hapana kusviba
3.Chroma
Mushure mokunge sampuro yacho yakavhenganiswa zvakaenzana, inoiswa mukati mechubimimetric chubhu, uyezve makumi maviri nemakumi matatu nemakumi matatu # inoteedzerwa mune mamwe machubhu emicherimetric. Ipapo, inoiswa mukati meye colorimetric chubhu furemu zvichiteerana. Tora girazi rekuenzanisa kwemavara uye uverenge iyo nhamba yemuenzaniso uri padyo neyakajairika chromaticity
4.Ester zvemukati
Iyo bvunzo nzira yezvigadzirwa zvemafuta zvemukati yaive capillary column gasi chromatography. Mushure mekuridzwa kwechiridzwa uye hwaro hwekutanga hwadzikamiswa, masampuli akaiswa jekiseni ne microglass injector kuyera nzvimbo yepamusoro yeboka rega rega, iyo yakaverengerwa maererano nefomula kana chromatographic data processor, uye kukosha kwemukati kwakawanikwa zvakawandisa nenzvimbo yekumisikidza nzira.
5.Acid kukosha
Pimha ethanol mukatatu-bhodhoro wobva wawedzera 3-4 madonhwe e phenolphthalein chiratidzo.Titrate neNaOH solution kune yakajeka pink color.Wean 50 ± 0.01g sampuli mu250ml triangulation flask.Wedzera iyo ethanol solution uye zunza mushe. Mhinduro yeNaOH inopera uye huwandu hwesodium hydroxide yakadyiwa yakanyorwa.
6.Thermal kugadzikana
Wedzera sampuro kubheaker, yakaiswa mukati me180 ℃ + 2 ℃ kuomesa hovhoni, tembiricha yenguva dzose kwemaawa maviri. Bvisa uye utonhorere kukamuri tembiricha, wozoiisa mune rimwe risina kuchena colorimetric chubhu. Isa iyo # 20 uye # 30, zvichiteerana, mune mamwe maviri ekukuya muromo plug isina colorimetric chubhu. Vapinze mune pombi rack. Shandisa girazi kuti uenzanise ruvara uye verenga nhamba yemuenzaniso uri padyo neyakajairika chromaticity
