无尘车间环氧地面水泡解决措施都有哪些?

来源:http://www.henganjh.cn │ 发表时间:2019-12-30 

大气的温度随着白天、夜晚和季节的变化而变化,上升或下降。水和气体在袋子里凝结形成小水滴,压力也随之减小。由于鼓形环氧层的强度,鼓体无法恢复到原来的状态,导致鼓体负压。这样,在基层含有水分的水分被吸进,增加了水在袋子里产生。当第二天温度上升时,由于袋子中可蒸发的水增加,产生了更大的压力,使得桶的体积再次膨胀。结果发现,在鼓的开口底部有一些白色的小点,形状呈峰状和凹状,这是与鼓底部相连的水渠。这种正在发育的隆起称为“活隆起”。鼓发展到一定规模时,由于干燥的基础,“水源”被切断,还因为包又大又平,减少向上撕裂力,和一些环氧层鼓受到高温干燥和热气腾腾的作用。随着温度的升降,环氧树脂层上的张力大小不一,导致环氧树脂层疲劳老化。在外力作用下,部分膨胀的环氧树脂层先破裂。直接破坏环氧树脂层的美观,无尘车间密闭室的性能和耐久性。必须根据工程的实际情况采取措施,防止水疱的形成。
  The temperature of the atmosphere changes with the change of day, night and season, rising or falling. Water and gas condense in the bag to form small drops of water, which reduces the pressure. Due to the strength of the drum shaped epoxy layer, the drum body can not be restored to the original state, resulting in negative pressure of the drum body. In this way, the moisture contained in the base layer is absorbed, increasing the generation of water in the bag. When the temperature rises the next day, the volume of the bucket expands again due to the increase of the evaporable water in the bag, which creates a greater pressure. The results show that there are some small white spots at the bottom of the opening of the drum, which are in the shape of peaks and concavities. This is the canal connected with the bottom of the drum. The developing uplift is called "live uplift". When the drum develops to a certain scale, due to the drying basis, the "water source" is cut off, and because the package is large and flat, the upward tearing force is reduced, and some epoxy layer drums are affected by high-temperature drying and hot air. With the rise and fall of temperature, the tension on the epoxy resin layer varies, leading to the fatigue aging of the epoxy resin layer. Under the action of external force, the partially expanded epoxy resin layer breaks first. It can directly destroy the beauty of epoxy resin layer and the performance and durability of the airtight chamber in the dust-free workshop. Measures must be taken according to the actual situation of the project to prevent the formation of blisters.
山东无尘车间
  1. 解决无尘清洁车间环氧层起泡问题,主要解决环氧地坪施工中的“三怕”问题。
  1. Solve the foaming problem of the epoxy layer in the dust-free cleaning workshop, mainly solve the "three fears" problem in the construction of the epoxy floor.
  (1)怕水;(2)晒太阳;(3)怕灰尘。
  (1) Be afraid of water; (2) bask in the sun; (3) be afraid of dust.
  2. 采取措施预防水疱:
  2. Take measures to prevent blisters:
  防水层在洁净车间的环氧地坪上制成,防止水、气向上渗漏,将基层或防水层含水率控制在8%以内。基础或防水层抗压强度大于20MPa,进行环氧施工。
  The waterproof layer is made on the epoxy floor of the clean workshop to prevent water and air from leaking upward, and the moisture content of the base course or waterproof layer is controlled within 8%. If the compressive strength of foundation or waterproof layer is greater than 20MPa, epoxy construction shall be carried out.
  改善环氧树脂层与基层或防水层的附着力,克服初始水疱的膨胀力,避免水疱的发生。在施工洁净车间地面环氧层时,底层涂料应质量良好,一是让部分环氧渗透到基层或防水层中形成一个整体;二是提高附着力,减少固化后材料或化学气体的残留。
  Improve the adhesion between epoxy resin layer and base or waterproof layer, overcome the expansion force of initial blister, and avoid the occurrence of blister. During the construction of the epoxy layer on the ground of the clean workshop, the bottom coating shall be of good quality. One is to let part of the epoxy penetrate into the base or waterproof layer to form a whole; the other is to improve the adhesion and reduce the residual material or chemical gas after curing.
  清洁车间环氧地坪施工结束后应避免阳光照射,减少环氧地坪表面与内部的温差。
  After the construction of the epoxy floor in the cleaning workshop, the sunlight shall be avoided to reduce the temperature difference between the surface and the interior of the epoxy floor.
  基层或防水层的施工必须清洁。施工后的无尘车间环氧地坪与基层或防水层无缝隙。
  The construction of base course or waterproof layer must be clean. There is no gap between the epoxy floor of the dust-free workshop and the base or waterproof layer after construction.
  总之,防水材料的选择必须有以下几点,
  In short, the selection of waterproof materials must have the following points,
  (1)不渗透性;
  (1) Impermeability;
  (2)抗压强度大于20MPa;
  (2) Compressive strength is greater than 20MPa;
  (3)与地面附着力强;
  (3) Strong adhesion with the ground;
  (4)容易与环氧树脂粘结形成一个整体。为保护成品,施工结束后3天内不得使用防水层。
  (4) Easy to bond with epoxy resin to form a whole. In order to protect the finished product, the waterproof layer shall not be used within 3 days after the completion of construction.
