抹面砂浆和腻子粉粘度越强越好吗?

来源:https://www.jnfhjc.com 日期:2019-06-19 发布人:admin

  现在一些片面的认为聚合物砂浆墙腻子粘合强度越快越好,越好,越有弹性,越好,事实上并非如此,形成水泥水化的力量之后,是刚性的,不能灵活,所谓的弹性是没有达到正常的水泥强度和高弹性材料密封能力强,它可以关闭或甚至完全封闭毛孔水泥,妨碍水泥水化,防止水泥使用自然条件下进行自我维护(呼吸),不利于水泥内应力的释放。

  Now some people unilaterally think that the bonding strength of putty of polymer mortar wall is faster, better, better, more elastic, better. In fact, this is not the case. After forming the strength of cement hydration, it is rigid and can not be flexible. The so-called elasticity is that it can not reach the normal cement strength and the sealing ability of high elastic material is strong. It can close or even completely seal porous cement, hinder cement hydration and prevent water. Self-maintenance (breathing) of mud under natural conditions is not conducive to the release of internal stress in cement.
  聚合物灰泥砂浆,外墙腻子粘结强度高,就材料性能而言,水泥是无机水硬性胶结材料,其粘结强度好,即使:4相比,水泥水泥砖块、石头,但前提条件是充分水化,由于水泥水化、凝结硬化是一个连续的过程,水泥的强度形成和稳定性是一个渐进的和相当长的过程,水化,凝结后,凝结硬化的结果取决于水泥和混凝土的水化程度通过使用自我维护的能力,自然条件,也就是说只要水泥水化条件好,良好的维护状态,几年后甚至可能经过10年的水泥强度会增加,将永远不会ErSanTian可以实现理想或28天强度,水泥的强度是在水面上实现的,而不是添加胶改善力量,这是我们应该学习的经验和教训。
  Polymer mortar and putty of exterior wall have high bonding strength. As far as material performance is concerned, cement is an inorganic hydraulically cementing material. Its bonding strength is good. Even if: 4 compared with cement bricks and stones, the precondition is full hydration. Because cement hydration and setting hardening are a continuous process, the strength formation and stability of cement is a gradual and rather long process. After the first setting, the result of setting and hardening depends on the degree of hydration of cement and concrete by using self-maintenance ability, natural conditions, that is to say, as long as the cement hydration condition is good and the maintenance condition is good, the strength of cement may increase after 10 years, and ErSanTian will never achieve the ideal or 28-day strength. The strength of cement is realized on the water surface, but not on the water surface. It is adding glue to improve strength, which is the experience and lesson we should learn.

  我们认为是聚合物水泥抹灰浆、主要原材料、外墙腻子和裂缝,主要是因为水泥水化后发生在干燥收缩的过程,所以我们更应该控制水泥材料特性和机理的基础上,选择水泥水化,节约用水,减少和控制水泥强度和混凝土的干燥收缩力量可以形成功能高分子产品,这是目前主要的裂缝,主要的技术解决方案。
  We believe that polymer cement mortar, main raw materials, external wall putty and cracks are mainly due to the drying shrinkage process of cement after hydration, so we should control the characteristics and mechanism of cement materials, choose cement hydration, save water, reduce and control the strength of cement and the drying shrinkage force of concrete to form functional polymer products. This is the current situation. The main cracks, the main technical solutions.
  其他方面,在基层问题上,应注意基层强度的平整度、材料的差异性以及裂缝的预处理等,在施工方法上应注意的是,不应敷太厚,如需敷太厚,应分两次或多次。
  Otherwise, in the grass-roots problem, attention should be paid to the uniformity of the strength of the grass-roots, the difference of materials and the pre-treatment of cracks. In the construction method, attention should be paid to that the thickness should not be too thick. If the thickness is too thick, it should be divided into two or more times.
  生产设备。有许多类型的生产设备,和选型很重要,从很多方面,如面积、能耗、设备投资金额、生产效率,安装、维护成本,方便操作和维护,工人的劳动强度,混合均匀,粉尘排放,噪音,设备耐用、经济和实用性。
  Production equipment. There are many types of production equipment, and selection is very important, from many aspects, such as area, energy consumption, equipment investment amount, production efficiency, installation and maintenance costs, easy operation and maintenance, labor intensity of workers, uniform mixing, dust emission, noise, equipment durability, economy and practicability.
  聚合物砂浆墙腻子开裂、裂缝的关键技术,是完全理解水泥材料的性质,在水泥水化的选择的基础上,能够可持续水和水泥的自我维护,减少水泥干燥收缩力,改善水泥后期强度的稳定性和功能高分子产品,可以有效地从根本上解决裂纹的问题,裂缝。
  The key technology of putty cracking and cracking in polymer mortar wall is to fully understand the properties of cement materials. On the basis of the choice of cement hydration, it can sustain self-maintenance of water and cement, reduce drying shrinkage of cement, improve the stability of late strength of cement and functional polymer products. It can effectively fundamentally solve the problem of cracking and cracking.
