Zopangira anayendera
Pofuna kuonetsetsa kuti zinthu zili bwino, timayendera mosamalitsa zopangira, malinga ndi miyezo yaku China.
Kuyesa kwa Plasticizer
1.Batch iliyonse ikadzafika, pafupifupi zitsanzo za 500ml zidzatengedwa kuti zikayese.
Mayeso a 2.Aparar: colorless ndi mandala, madzi sampuli yankho, palibe chodetsa
3. Chikoroma
Chitsanzocho chitasakanikirana mofanana, chimalowetsedwa mu chubu cha colorimetric, kenako 20 # ndi 30 # zimayikidwa m'machubu iwiri ina. Kenako, imayikidwa mu colorimetric chubu chimango motsatana. Tengani galasi lofananitsa mitundu ndipo werengani nambala yazitsanzo pafupi kwambiri ndi chromaticity yoyenera
4.Ester okhutira
Njira yoyesera yamafuta azinthu inali capillary column mpweya chromatography. Chidacho chidasinthidwa ndikukhazikika koyambira, zitsanzo zidabayidwa ndi microglass injector kuti ayese gawo lalikulu la gulu lirilonse, lomwe limawerengedwa molingana ndi kapangidwe kake kapenanso chromatographic data processor, ndipo mtengo wake wapezedwa kochulukirapo ndi njira yokhazikika m'deralo.
5. Mtengo wa asidi
Meya wa ethanol mu botolo la makona atatu ndipo onjezerani madontho 3-4 a phenolphthalein chizindikiro.Titrate ndi yankho la NaOH ku mtundu wowala wapinki.Pimani 50 ± 0.01g sampuli mu botolo la triangulation 250ml. Onjezani yankho la ethanol ndikugwedeza bwino. Yankho la NaOH limamalizidwa ndipo kuchuluka kwa sodium hydroxide yomwe amadya imalembedwa.
6.Kukhazikika kwa kutentha
Onjezerani nyemba pa beaker, yoikidwa mkati mwa 180 ℃ + 2 oven kuyanika uvuni, kutentha kwanthawi zonse kwa maola awiri. Tulutsani ndi kuziziritsa mpaka kutentha, kenako nkumuyika mu chubu chimodzi chopanda utoto. Ikani # 20 ndi # 30, motsatana, muzitsulo zina ziwiri zopera pakamwa zopanda utoto wopanda utoto. Ikani iwo mu chikwangwani cha chitoliro. Gwiritsani ntchito galasi kufananizira utoto ndikuwerenga nambala yazitsanzo pafupi kwambiri ndi chromaticity yoyenera
