Description
技术领域technical field
本实用新型涉及一种聚氨酯注浆材料试件成型模具。The utility model relates to a polyurethane grouting material test piece forming mold.
背景技术Background technique
注浆材料种类繁多，应有广泛。近30多年来，有机化学注浆材料发展迅速，聚氨酯类注浆材料作为有机化学浆液的一种，以其良好的可注性、黏结性，优秀的堵水和抗渗性能广泛的被国内外学者研究和应用。在对聚氨酯类注浆材料的研究中，需要制备小尺寸的试件用于试验研究。现有的试件制备模具多数为带有两个螺旋式封盖的金属管组成的腔体，由于聚氨酯类材料具有一定的粘结性、膨胀性，同时个别种类材料反映较快、反应时间较短，这些特点会在试件制备时产生各类问题，主要集中在模具密闭性差、试件成型后模具上下密封盖无法拧开等。例如，由于材料具有黏性和膨胀性，同时其本身渗透性较强，在模具封盖拧紧后，往往会有一定量的浆液盖口缝隙处渗出，再加上浆液与封盖顶部完全黏结接触，使得封盖与金属管、浆液紧密黏结在一起，无法拧开；另外部分材料反映时间较快也会导致在封盖尚未拧紧时管内浆液已经反应膨胀并溢出模具，使模型制备失败，影响试验进程。There are many kinds of grouting materials and should be widely used. In the past 30 years, organic chemical grouting materials have developed rapidly. As a kind of organic chemical grout, polyurethane grouting materials are widely used at home and abroad for their good injectability, cohesiveness, excellent water blocking and impermeability properties. Scholars research and apply. In the research on polyurethane grouting materials, it is necessary to prepare small-sized specimens for experimental research. Most of the existing sample preparation molds are cavities composed of metal tubes with two screw-type covers. Because polyurethane materials have certain cohesiveness and expansion properties, and some types of materials react quickly and the reaction time is relatively short. In short, these characteristics will cause various problems during the preparation of the test piece, mainly focusing on the poor airtightness of the mold and the inability to unscrew the upper and lower sealing covers of the mold after the test piece is formed. For example, due to the viscosity and expansibility of the material, and its own strong permeability, after the mold cover is tightened, a certain amount of slurry often seeps out from the gap of the cover, and the slurry is completely bonded to the top of the cover. , so that the cover is tightly bonded to the metal tube and the slurry, and cannot be unscrewed; in addition, the fast reaction time of some materials will cause the slurry in the tube to react and expand before the cover is tightened and overflow the mold, which makes the model preparation fail and affects the test. process.
