The temperature in the monomer storage tank must be kept below ___°C to prevent self-polymerization; its pressure is usually 0.18–0.27 Mpa (gauge pressure). Answer: 1:4； 15.5 ；
Under normal conditions, the feeding ratio of recycled monomer to fresh monomer is (1:4). The temperature of the monomer storage tank is kept below (15.5)°C to prevent self-polymerization, and its pressure is usually between 0.18-0.27 Mpa (gauge pressure)
