Qhov sib txawv tseem ceeb ntawm ob thiab triple pressed stearic acid yog tias triple pressed stearic acid yog refined dua li ob npaug nias stearic acid.
Stearic acid yog cov roj saturated fatty acid. Nws yog ib qho khoom waxy compound. Cov tshuaj formula ntawm no compound yog C17H35CO2H. Tsis tas li ntawd, cov esters thiab ntsev ntawm stearic acid yog stearates. Ob npaug nias thiab triple nias stearic acid yog ob qib lag luam ntawm stearic acid.
Ob-Pressed Stearic Acid yog dab tsi?
Ob npaug nias stearic acid yog qib lag luam ntawm stearic acid uas tsis tshua zoo dua li triple pressed stearic acid. Hauv lwm lo lus, ob npaug nias stearic acid muaj impurities thiab tsis xav tau ntau dua li triple pressed daim ntawv. Txawm li cas los xij, ob daim ntawv nias tseem muaj nyob rau hauv kev ua lag luam, txawm hais tias nws tsis muaj ntau.
Daim duab 1: Qhov tshwm sim ntawm Stearic Acid
Feem ntau, cov khoom ntawm qib kev lag luam no nyob ntawm cov chaw tsim khoom. Qee cov khoom tseem ceeb ntawm ob npaug nias stearic acid yog raws li hauv qab no (raws li Tradeasia International pte ltd.):
- Acid nqi=209.0 – 215.0 mgKOH/g

Triple-Pressed Stearic Acid yog dab tsi?
Triple pressed stearic acid yog qib kev lag luam niaj hnub ntawm stearic acid. Nws yog zoo refined kom tshem tawm cov impurities thiab pliaj tebchaw. Qhov tseeb, nws yog purer dua ob npaug nias stearic acid. Qee yam khoom tseem ceeb ntawm qib kev lag luam no yog raws li hauv qab no:
- Acid nqi=207.0 – 212.0 mgKOH/g
- Saponification tus nqi=208 - 213 mgKOH/g
- Titer=54 – 56.5°C
- Iodine tus nqi=siab tshaj 0.5 gI2/100 g
Daim ntawv thov ntawm Triple Pressed Stearic Acid
| Khoom noj khoom haus thiab dej haus | Siv ua tawv tawv rau cov khoom qab zib |
| Lubricants | Raws li thickener hauv roj, raws li pwm tso cov roj nplaum, thiab lwm yam. |
| Rubber thiab plastics | Raws li viscosity depressant hauv plastics thiab ua tus accelerator thiab activator hauv kev ua roj hmab. |
| kev saib xyuas tus kheej | Raws li emulsifier, hauv kev tsim cov tshuaj ntxuav tes thiab xab npum, thiab lwm yam. |
Qhov txawv ntawm Ob thiab Triple Pressed Stearic Acid yog dab tsi?
Oib vs Triple Pressed Stearic Acid |
|
| Ob npaug nias stearic acid yog qib lag luam ntawm stearic acid uas yog tsawg-refined dua triple pressed stearic acid. | Triple pressed stearic acid yog qib kev lag luam niaj hnub ntawm stearic acid uas tau ua kom zoo heev. |
| Purity | |
| Sib piv, tsawg ntshiab | Purer, thaum muab ob qho tib si stearic acids |
| Iodine nqi | |
| Thaum muab piv ob, tus nqi iodine siab heev | sib piv, qis heev |
Summary – Ob npaug vs Triple Pressed Stearic Acid
Stearic acid yog saturated fatty acid compound. Nws muaj nyob rau hauv ob qib kev lag luam loj li ob daim ntawv nias thiab triple pressed daim ntawv. Qhov sib txawv tseem ceeb ntawm ob thiab triple pressed stearic acid yog tias triple pressed yog ntau refined dua ob npaug nias. Yog li ntawd, triple pressed yog purer thiab muaj ib tug tsawg heev iodine nqi tshaj ob-nias.
