    摘要： A die pre-heating system comprises at least one die oven, a robotic hoist and processing structure in communication with the hoist and the at least one die oven. The processing structure is configured to control the hoist to permit an extrusion die to be loaded into the at least one die oven and to be unloaded from the at least one die oven. The processing structure is also configured to cause the at least one die oven to operate according to a production formula for pre-heating an extrusion die loaded therein.

    摘要： Polyvinyl alcohol is manufactured by the alcoholysis of polyvinyl esters, in particular polyvinyl acetate, in the presence of a basic catalyst and in the presence of an alkanol as the solvent. The degree of polymerization of the polyvinyl ester used as the starting material is normally within the range from 400 to 10,000. The catalyst used is preferably an alkali metal hydroxide or an alkali metal alcoholate. The alcoholysis is effected by first preparing a solution of the polyvinyl ester, which is then trans-esterified at an elevated temperature. The resulting polyvinyl alcohol exhibits a high degree of purity. It is suitable for use as a base material for the production, by thermoplastic methods, of shaped articles, chiefly by compression molding, injection molding and extrusion.

    摘要翻译： 聚乙烯醇通过在碱性催化剂的存在下和作为溶剂的链烷醇的存在下，通过聚乙烯酯，特别是聚乙酸乙烯酯的醇解来制备。 用作原料的聚乙烯酯的聚合度通常在400〜10,000的范围内。 所使用的催化剂优选为碱金属氢氧化物或碱金属醇化物。 醇解通过首先制备聚乙烯基酯的溶液来实现，然后在升高的温度下将其聚酯化。 所得聚乙烯醇显示出高纯度。 适用于通过热塑性方法生产成型制品的基材，主要通过压缩成型，注射成型和挤出成型。
