Hydroxypropyl methylcellulose plays a key role in improving the performance of dry mixed mortar
3. Pure HPMC cellulose aqueous solution is clear, with high light transmittance, and water retention rate ≥ 97%; The adulterated HPMC cellulose aqueous solution is turbid, and the water retention rate is difficult to meet the requirements. The light transmittance of the aqueous solution is good, which indicates that the product contains less insoluble substances and high content of active ingredients.
