造成部分玻璃对流传递能量的流失的因素

文章出处:http://www.jnkdblgd.com/ 人气: 发表时间:2022-06-13
对流传递是玻璃能量传递方式之一,是由于在玻璃的两侧具有温度差,造成空气在冷的一面下降而在热的一面上升,产生空气的对流,而造成能量的流失。造成这种现象的原因有几个:
Convection transfer is one of the energy transfer modes of glass. Due to the temperature difference on both sides of the glass, the air drops on the cold side and rises on the hot side, resulting in air convection and energy loss. There are several reasons for this phenomenon:
一是玻璃与周边的框架系统的密封不良,造成窗框内外的气体能够直接进行交换产生对流,导致能量的损失;
First, the poor sealing between the glass and the surrounding frame system results in the direct exchange of gas inside and outside the window frame, resulting in convection, resulting in the loss of energy;
二是玻璃的内部空间结构设计的不合理,导致玻璃内部的气体因温度差的作用产生对流,带动能量进行交换,从而产生能量的流失;
Second, the unreasonable design of the internal space structure of the glass leads to the convection of the gas inside the glass due to the temperature difference, which drives the energy exchange, resulting in the loss of energy;

三是构成整个系统的窗的内外温度差较大,致使玻璃内外的温度差也较大,空气借助冷辐射和热传导的作用,在玻璃的两侧产生对流,然后通过玻璃整体传递过去,形成能量的流失。合理的玻璃设计,可以降低气体的对流,从而降低能量的对流损失。
Third, the temperature difference between the inside and outside of the windows that make up the whole system is large, resulting in a large temperature difference between the inside and outside of the glass. With the help of cold radiation and heat conduction, air convection occurs on both sides of the glass, and then passes through the glass as a whole, resulting in the loss of energy. Reasonable glass design can reduce the convection of gas, thus reducing the convection loss of energy.
此外在选择办公室玻璃隔断时要选择安全的玻璃,钢化玻璃属于安全玻璃,普通的玻璃易碎,钢化之后能够增强玻璃的坚硬度,作为办公室隔断使用可以更加安全一些。隔断五金配件也要选择好的材料,支脚、门锁、拉手、夹槽、框架等选择不锈钢材料也会增加办公室隔断的使用寿命。
In addition, when selecting the office glass partition, you should choose safe glass. Tempered glass belongs to safe glass. Ordinary glass is fragile. After tempering, it can enhance the hardness of the glass. It can be safer to use as an office partition. Partition hardware fittings should also be made of good materials. Choosing stainless steel materials for legs, door locks, handles, clamping slots, frames, etc. will also increase the service life of office partitions.
办公室隔断玻璃产品失效的典型现象,是在玻璃间隔层内部结露、进水,这样的产品不仅影响整个玻璃的外观,还影响整个玻璃的热性能,对玻璃寿命产生影响的关键因素是密封胶的耐老化性能和干燥剂的吸附能力的大小,而决定因素是密封胶的性能。
The typical phenomenon of the failure of office partition glass products is the condensation and water ingress inside the glass partition. Such products not only affect the appearance of the whole glass, but also affect the thermal performance of the whole glass. The key factors affecting the life of the glass are the aging resistance of the sealant and the adsorption capacity of the desiccant, and the decisive factor is the performance of the sealant.
济南玻璃安装厂家认为对玻璃隔断的使用寿命影响因素还有后期的保养,在日常过程中要注意对玻璃隔断的保养,避免长期碰撞玻璃隔断,使其固定性减小,造成松动现象。保证玻璃隔断干净整洁防止灰尘等物质影响玻璃胶的粘性。
Jinan glass installation manufacturers believe that the service life of the glass partition is also affected by later maintenance. In the daily process, attention should be paid to the maintenance of the glass partition to avoid long-term collision with the glass partition, reducing its fixity and causing looseness. Ensure that the glass partition is clean and tidy to prevent dust and other substances from affecting the adhesion of the glass adhesive.
