| Message: | SD-3（Hot Plate Powder）：SD-3 is moisture-proof magnesium oxide, GRADE C, used for heating elements such as hot plate made by oil hydraulic press, commonly known as hot plate powder ,which has high moisture-proof property. The heating wire can be put in the MgO powder ,then press to be any shape or pressed in the metallic channel. We suggest to dry the heating elements at 200℃-400℃ for 2 ~ 4 hours after shaping.low-temperature Mgo powderProduct Info StyleSD-8 SD-6SD-3 SD-99 SD-99A M.S.M22SR33ST 44 5A 5AWorking temperatuer℃≦1100≦650≦500≦700≦800Velocity of flow/Flow rate/DensityF.Density(g/c.c)2.33±0.032.33±0.032.20±0.042.30±0.032.30±0.03Static flow(s/100g)36±238±238±238±238±2F.R(s/100g)185±15185±15195±15200±15200±15US Standard Sieves(％retained)+40(425um)≦0.1≦0.1≦0.2≦0.1≦0.1+60(250um)30±730±730±730±730±7+83(180um)20±620±620±620±620±6+140(106um)25±625±625±625±625±6+200(75um)10±510±510±510±510±5+325(45um)10±510±510±510±510±5-325(-45um)4±24±24±24±24±2Technical Chemical AnalysisMgO97±196±196±196±196±2CaO≦0.86≦1.4≦1.4≦1.4≦1.1SiO2≦1.2≦1.5≦1.5≦1.5≦1.1Fe2O3≦0.26≦0.3≦0.3≦0.3≦0.26AI2O3≦0.08≦0.16≦0.16≦0.16≦0.12Watt/sq cm≦10≦6≦5≦6≦7 url:http://www.superbheater.com |
