(PMMA) heat-polymerized resin (HPR) was used as the repaired material, cold-polymerized material (CPR) for the repairs, and different variants of alumina abrasive blasting (AB), methyl methacrylate (M), ethyl acetate (EA), methylene chloride (CH), and isopropyl alcohol (IA) treatments ...
a它们的制备方法和工艺流程不同,最后的纯度也不同,粗异丙醇的含量只有87%,而经过进一步提纯的异丙醇含量则达到99.7以上 Their preparation method and the technical process are different, the final purity is also different, thick isopropyl alcohol content only then 87%, but passes through the isopropyl ...
The mobile phase consisted of (A) MeOH/H2O/formic acid (HCOOH) (60:40:0.2, v/v/v) and (B) MeOH/isopropyl alcohol/HCOOH (60:40:0.2, v/v/v), both containing 10 mM NH4OAc. Qualitative analysis of sphingolipids was performed on an Agilent ultra high definition (UHD) 6550 ...
The ethanol and acetaldehyde were captured in a solution of water and isopropyl alcohol (IPA). The IPA is used to measure the relative concentrations of each alcohol using a gas chromatograph and carbon dioxide concentrations are measured using a KOH solution method....
The molecular-weight dependence of the glass-transition temperature (Tg) of a series of atactic polyacrylonitriles (PAN)s was studied by inverse gas chromatographic (IGC) analysis. PANs having different molecular weights were prepared by either; (i) the addition of isopropyl alcohol as a chain-...
Grab a microfiber cloth and dampen it with some warm water or isopropyl alcohol. Start scrubbing the stains or dirty areas of the mousepad while avoiding the edges and the electronics box. For stubborn stains, mix a tiny amount of mild dish soap with warm water and use it to dampen one ...
