How To Clean Felt With Hydrochloric Acid
Dec. 31, 2019
In the process of using felt, there may be stains, so the cleaning of the felt must be paid special attention. So how to use hydrochloric acid to clean the felt? We can consult Wool felts manufacturer.
When cleaning the felt, you can first clean the clay and pigment polyphosphate, etc., and then wash the aluminum complex with hydrochloric acid, sulfuric acid, etc., 1000L water temperature at 40-50 degrees plus 2KG nonionic surface-active solvent and 4KG tripolyphosphoric acid Wash 100KG felt. Wash for 10-20 minutes each time, then rinse the resin on the felt according to water rinse, and use a special solvent formula for cleaning.
It should also be noted that when cleaning the felt, it should be gently pressed by hand, and the dirtier parts should only be gently scrubbed. Do not brush with the brush. After cleaning, hang it in a ventilated place to dry naturally. For drying, use low-temperature drying.
Before using the felt, it is best to test its properties, and then use it with confidence, including abrasion resistance and breaking strength.
As for the abrasion resistance test of felt, it is mainly carried out on a fabric friction strength machine. The needle of the fabric friction strength machine is set to the zero position, and then the felt sample is clamped flat and in a tense state. For the breaking strength test of felt, the test is performed on a fabric strength machine. Under specific environmental conditions, the samples are clamped one by one in the jaws of the strongest machine and the lower holder one by one, and the breaking strength of each sample is measured. Arithmetic average, the average value is the breaking strength of the felt.
When you buy a product, you can judge the quality of the felt by density, because it will affect the quality of the product.
If the density of the felt exceeds normal values, the felt will lose its elasticity, which is very inconvenient in the application. If the felt is mainly used for polishing, you can choose a higher density felt, but if you focus on elasticity, you can choose a less dense felt. Note that if the density of the felt is too small, the felt will lose its abrasion resistance, so when you buy it, you can choose according to your own use. In addition, the quality of the felt is also related to the thickness of the wool and the gloss of the felt.
