What is PH? PH value, also known as acid-base value, is a symbol used chemically to measure the ratio of acidity to alkalinity of a liquid. In the polyurethane synthesis reaction, the PH of the system has a prominent impact on the reaction, and the proper application of acid-base adjustment techniqu

Q&A：1. Q: What is the max temperature of molecular sieve powder in adhesive production? A：Below 500 ℃ is ok, the molecular sieve raw powder will lose crystal water when at 550 ℃. When the temperature reduces to the indoor temperature, it will absorb water to recover. When the roasting temperature

How to inspect the Residue of Molecular Sieve Powder? Firstly, What is Molecular Sieve Powder Residue?The sieve residual is an expression of the fineness of the powder material, the ratio of the mass of a certain mass of powder material left on the sieve part after sieving on a standard sieve. The
