The solder paste has become one of the most indispensable brazing and soldering materials in surface mount technology (SMT), and its performance affects the quality of welding directly. The independently-designed lead-free solder paste in the lab has the fine performance when synthesized initially. However, the performance of solder paste degraded during the storage. So the aim of the article is to...
Partially gelatinized corn starch (PGCS) was used for sizing cotton yarn in the search for potential sustainable and environmentally friendly warp-sizing agents as substitutes for poly vinyl alcohol. PGCS was prepared by a constant temperature method (CTM). The viscosity stability of PGCS was investigated and characterized by wide-angle X-ray diffraction, differential scanning calorimetry, polarized...
Protein hydrolysis is used widely in the food industry for the purpose of improvement of food or industrial quality, and the processing exists concurrently or subsequently with starch pasting. The effects of protein hydrolysis using papain, pepsin, trypsin, and dithiothreitol (DTT) on flour pasting properties were here investigated at five set concentrations. There were notable decreases in the peak,...
