造成部分玻璃對流傳遞能量的流失的因素
對流傳遞是玻璃能量傳遞方式之一,是由于在玻璃的兩側具有溫度差,造成空氣在冷的一面下降而在熱的一面上升,產生空氣的對流,而造成能量的流失。造成這種現象的原因有幾個:
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:
一是玻璃與周邊的框架系統的密封不良,造成窗框內外的氣體能夠直接進行交換產生對流,導致能量的損失;
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;
二是玻璃的內部空間結構設計的不合理,導致玻璃內部的氣體因溫度差的作用產生對流,帶動能量進行交換,從而產生能量的流失;
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;
三是構成整個系統的窗的內外溫度差較大,致使玻璃內外的溫度差也較大,空氣借助冷輻射和熱傳導的作用,在玻璃的兩側產生對流,然后通過玻璃整體傳遞過去,形成能量的流失。合理的玻璃設計,可以降低氣體的對流,從而降低能量的對流損失。
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.
此外在選擇辦公室玻璃隔斷時要選擇的玻璃,鋼化玻璃屬于玻璃,普通的玻璃易碎,鋼化之后能夠增強玻璃的堅硬度,作為辦公室隔斷使用可以更加一些。隔斷五金配件也要選擇好的材料,支腳、門鎖、拉手、夾槽、框架等選擇不銹鋼材料也會增加辦公室隔斷的使用壽命。
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.
辦公室隔斷玻璃產品失效的典型現象,是在玻璃間隔層內部結露、進水,這樣的產品不僅影響整個玻璃的外觀,還影響整個玻璃的熱性能,對玻璃壽命產生影響的關鍵因素是密封膠的耐老化性能和干燥劑的吸附能力的大小,而決定因素是密封膠的性能。
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.
濟南玻璃安裝廠家認為對玻璃隔斷的使用壽命影響因素還有后期的保養(yǎng),在日常過程中要注意對玻璃隔斷的保養(yǎng),避免長期碰撞玻璃隔斷,使其固定性減小,造成松動現象。保證玻璃隔斷干凈整潔防止灰塵等物質影響玻璃膠的粘性。
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.
