1. hemical Nature thiab Architectural Characteristics
1.1 Molecular Make-up thiab Self-Assembly Actions
(Calcium Stearate hmoov)
Calcium stearate hmoov yog cov xab npum hlau tsim los ntawm kev ua haujlwm nruab nrab ntawm stearic acid– ib tug C18 saturated fatty acid– nrog calcium hydroxide los yog calcium oxide, tsim cov tshuaj formula Ca(C ₁₈ H ₃₅ O OB)OB.
Cov tshuaj no los ntawm cov chav kawm dav dav ntawm alkali ntiaj chaw steel soaps, uas nthuav tawm cov tsev amphiphilic vim lawv ob chav molecular style: ib polar, ionic “taub hau” (cov calcium ion) thiab ob ntev, nonpolar hydrocarbon “qab” muab tau los ntawm stearic acid chains.
Hauv lub xeev muaj zog, cov molecules nws tus kheej sib sau ua ke rau hauv cov txheej txheem lamellar los ntawm van der Waals kev sib txuas lus hauv nruab nrab ntawm cov tails hydrophobic, thaum lub ionic calcium chaw muab kev sib txuas lus architectural siv electrostatic pressures.
Txoj kev npaj sib txawv no txhawb nqa nws txoj haujlwm ua ob qho tib si dej-repellent tus neeg saib xyuas thiab lub roj, tso cai rau kev ua tau zoo ntawm ntau hom khoom siv.
Daim ntawv crystalline ntawm calcium stearate feem ntau yog monoclinic lossis triclinic, vam khom tej yam kev mob, thiab nthuav tawm thermal stability txog li 150– 200 ° C ua ntej yuav pib lwj.
Nws tsis tshua muaj solubility nyob rau hauv dej thiab feem ntau cov kuab tshuaj ntuj ua rau nws tshwj xeeb tshaj yog haum rau daim ntaub ntawv hu rau qhov zoo sib xws ntawm thaj chaw hloov kho yam tsis muaj leaching..
