天元直销 铸钢材料宝珠砂 耐火填充材料宝珠砂

     天元宝珠砂是铸造行业内的绿色环保耐火材料，在铸造中作为优良的铸造用型砂，可以避免铸件缺陷，同时铸件的成品率也得到了提高，是消失模填充砂、各种涂料骨料、各式型砂、各种芯砂、引流砂等。

    1、宝珠砂属中性材料，它耐高温、易溃散、结构致密、热导率大、高温稳定、不龟裂、抗酸、抗碱侵蚀。

    2、对酸性、碱性结合剂均可使用、树脂加入量可减少30-50，水玻璃加入量＜=4。

    3、具有良好的使用性，性价比远远超过铬铁矿砂、锆英砂，按体积比计价、只有铬矿砂的50，锆英砂的30。

    4、应用于水玻璃砂、树脂砂、精密铸造、消失模铸造及铜、铝件的抛光清理。

Tianyuan orb is sand casting refractory materials of green environmental protection of the industry, and as an excellent foundry sand in foundry, can avoid the casting defects, the yield of casting is improved at the same time, is gone, all kinds of coating aggregate, all kinds of green sand mold filling sand, a variety of core sand, sand drainage, etc.

1. Baozhu sand is a neutral material, it is resistant to high temperature, easy to break, dense structure, high thermal conductivity, stable temperature, no cracks, acid and alkali erosion.

2. For acid and alkaline binding agents, the amount of resin added can be reduced by 30 to 50, and the amount of water glass added < =4.

3. With good use, the cost performance is far more than that of chrome-iron ore and zirconium sand, and it is only 50 of the volume, only 50 of the chromium ore and 30 of zircon sand.

4. Applied to the polishing and cleaning of water glass sand, resin sand, precision casting, die casting and copper and aluminum parts.
