Discussion on experiment
.From the experiment the amount of oxalic acid in local plants. Spinach is a plant with oxalic acid the most, followed by is the betel leaves and plants containing oxalic acid is the smallest is correspondentsUSDA Agrucultured Research Service by spinach is out of oxalic 1090 mg / g 1088 100 betel leaves.4 mg / g and 100 correspondents 223.2 mg / 100 grams.
. ConclusionThe amount of oxalic acid in plants and 3 type has different quantity. Spinach is a plant that oxalic acid the most, followed by is the betel leaves and plants with citric acid ออกซาลิ smallest is correspondents
.Extracted from spinach has a weak acid, but when the paste with EM is pH 4.78
latex raw materials: substance fermentation from spinach was 100: 30. Effective in curing the latex faster sheet iron is easily, a beautiful color!From the experiment the tensilestrength of rubber sheet made radio results obtained. Rubber sheet with fermented from spinach to withstand tensile strength is better than the rubber in formic acid with the tensile resistance 2.5 Mega พาสคาล and 2.3 Mega พาสคาล respectively. Experimental results against fungi of raw rubber sheet. The result is a raw rubber curing with water spinach is fermented fungus up a little. But the raw rubber curing with acid for Mick's fungus full sheet.Clear zone effects that it is fermented from spinach is the width of the clear zone 0.07 cm but acid for Mick width of clear zone 0.05 cm
