玻璃鋼環氧樹脂防水層施工時要注意的事項-中英對照
The following matters should be paid special attention in the construction of glass steel epoxy resin water resistant layer:
①. 為了便于施工，應選用分子量不大于500，軟化點不大于30度的低分子量的環氧樹脂，9布10膠玻璃鋼環氧樹脂防水層常用品種為E-4和E-42環氧樹脂
For the convenience of construction, epoxy resin featured as molecular weight no higher than 500 and softened point no larger than 30 degrees should be adopted. E-4 and E-42 epoxy resin should be frequently adopted for 9 cloth 10 rubber glass steel epoxy resin water resistant layer.
②. 環氧樹脂在固化前是熱塑性的線型結構，因此施工時須加入固化劑，使其成為體形網狀結構。據本工程的施工條件，可選用C20固化劑或JA-1固化劑此兩種固化劑可常溫固化，也可在低溫、潮濕、帶水條件下固化。且此兩種固化劑低毒，無刺激性氣味，對操作人員無過敏現象。C20固化劑常溫時加入量為18～20%，低溫潮濕時為25～30%。JA-1固化劑常溫時加入量為15～20，低溫潮濕帶水時為20～25。
Epoxy resin refers to hot plastic linear structure before hardening, therefore hardener must be added before construction to change into net-shaped structure. According to the construction conditions of this project, C20 hardener or JA-1 hardener which can be hardened under normal temperature and also under low temperature, wet and water conditions can be adopted. The above two kinds of hardeners have low poisoning and no stimulating odor and thus are not allergic to operators. 18-20% C20 hardener should be added under normal temperature and 25-30% under low temperature and wet condition. 15-20% JA-1 hardener should be added under normal temperature and 20-25% under low temperature and wet & water condition.
③. 環氧樹脂在施工應用中，須加入一定比例的填料，在配置玻璃鋼打底料或環氧膠泥時需加入粉料，在配置環氧砂漿時應加入粉料和砂料。
In the construction applications, a certain ratio of filling material must be added to the epoxy resin. Pulverized material should be added in the preparation of glass steel base material or epoxy rubber mud. Pulverized material and sand material should be added in the preparation of epoxy slurry.
④. 玻璃布選用0.1～0.4厚，常用的玻璃布為有堿有捻或無堿無捻粗紗布，布表面宜浸潤劑亦選擇樹脂型，這種玻璃布易被環氧膠液浸透又能使環氧膠液與玻璃纖維結合牢固。
0.1-0.4 thick glass cloth should be adopted. Frequently used glass cloth should include alkali and twisted cloth or no alkali roving cloth. The surface sizing agent should be resin type. This kind og glass may be dipped by epoxy rubber liquid and can fasten epoxy rubber liquid and glass fibre.
⑤. 為便于施工操作，環氧樹脂需加入溶劑稀釋，常用溶劑為活化溶劑如甲苯、二甲苯、丙酮等，加入量應以滿足工藝要求為前提盡量少用。
For the convenience of construction operations, solvent should be added to the epoxy resin for dilution. Frequently used solvents should include activated solvents such as toluene, xylene and acetone. The dosage should be as little as possible under the condition of meeting the technical requirements.
⑥. 為加強環氧樹脂的抗沖擊能力，改善其脆性，須在環氧樹脂加入一些增韌劑，但用量不宜過多，否則，會影響環氧樹脂各方面的性能。
In order to strengthen the impact capability of epoxy resin and improve its brittleness, some toughening agent should be added to epoxy resin. But the dosage should be as little as possible. Otherwise, it may affect various performances of epoxy resin.
⑦. 環氧樹脂固化劑，稀釋劑是易燃有機物質，在施工現場和庫房均應采取防火措施，施工現場須配滅火器，并對工人加強安全防火教育。
Epoxy resin hardener and diluting agent refer to combustible organic substances. And fire-proof measures must be adopted in the construction site and warehouse. Fire extinguishers must be equipped and workers should be given fire prevention education.
⑧. 打底料、襯布膠料和面層膠料的施工配置，均要嚴格稱量，隨配隨用，充分搖勻，應根據施工人員多少、施工進度快慢分多次勤配快用。以免使用不及時，出現爆聚現象，導致不能使用。
Construction collocation of base paint, cloth rubber mass and surface layer rubber mass should be weighed strictly. The materials should be collocated and used and operated evenly. The principle of “frequent collocation and rapid use” should be adopted according to the number of workers and construction progress to prevent delayed use or failure in case of excessive demand.
⑨. 蓄冰槽防水保溫過程中，為保證施工工人的人身安全必須改革機械排風，一種方法連接排風管道排至室外。其二是將排風風管接至地下室的排風系統中，同時啟動排風機，通過排風系統將有毒氣體排至室外。
 In the water resistance and heat conservation process of ice tank, in order to ensure the safety of construction workers, mechanical ventilation must be reformed. One method is to connect the exhaust pipeline to the outside. The other method is to connect exhaust pipeline to the basement exhaust system and at the same time, start the fan and exhaust poisonous gas out of the room through such system.
