机制蜡壳的主要质量要求为:在暑热环境中不软化变形成“荔枝干”;严寒条件下仍有较好的抗震性能而不发脆。本文用 L9(3~1)正交试验优选结果,认为20～30℃室温下,较为理想的配方为:食品用石蜡68kg,高压聚乙烯3kg,蓖麻油1.5kg,钙化松香8kg,凡士林3kg,提纯地蜡6kg,松香8kg,蜂蜡4kg。 Mechanism The main quality requirements of the wax shell: In the summer heat environment does not soften the deformation into “lychee dry ”; still has better anti-seismic performance under cold conditions without brittle. In this paper, L9 (3 ~ 1) orthogonal test results show that 20 ~ 30 ℃ at room temperature, the more ideal formula: food paraffin 68kg, high pressure polyethylene 3kg, castor oil 1.5kg, calcified rosin 8kg, petrolatum 3kg, Pure wax 6kg, rosin 8kg, beeswax 4kg.
