雨季影響環氧地坪施工嗎?環氧地坪施工中有哪些注意事項?環氧地坪漆涂裝質量三分取決于涂料七分取決于施工,優質涂料若不采用嚴格的施工工藝不會得到優良的效果,因此施工對于環氧地坪漆來說是非常重要的。我們首先談下濕度對于環氧地坪施工的影響: 濕度,指的是空氣中水分的含量,一般用百分比來表示。如果有結露現象出現,說明空氣的相對濕度達到百分之百。根據環氧地坪漆施工要求規定,當空氣相對濕度高于85%時,是不能進行環氧地坪漆施工的,因為容易出現泛白、裂紋等弊病。濕度不僅影響環氧地坪漆的施工,更是會影響環氧地坪漆固化,濕度指數在過大的情況下才影響地坪涂裝,它的影響往往大于人們的想象。

Does the rainy season affect floor construction? What should we pay attention to in the construction of epoxy floor? The coating quality of epoxy floor paint depends on three parts of the coating and seven points of the coating depend on the construction. If the strict construction technology is not used, the excellent effect will not be obtained. Therefore, the construction of epoxy floor paint is very important. First of all, we talk about the influence of humidity on the construction of epoxy flooring: humidity refers to the content of moisture in the air, which is generally expressed by percentage. If condensation occurs, the relative humidity of air reaches 100%. According to the construction requirements of epoxy floor paint, when the relative humidity of air is higher than 85%, the construction of epoxy floor paint can not be carried out, because it is prone to white, cracks and other defects. Humidity not only affects the construction of epoxy floor paint, but also affects the curing of the floor paint. When the humidity index is too large, it affects the floor paint. Its influence is often greater than people imagine.

濕度過高,會引起涂裝表面結露,凝結的水會對固化劑造成破壞引起涂膜發白、失光、發黏、回黏等現象,大大降低表面裝飾效果,嚴重時造成返工。特別無溶劑面漆,表干時間一般較長,在涂漆后馬上下雨或在冬春季的傍晚涂漆都是有危險的.但有時因為業主要求工期,理想的天氣條件不易出現,這時就需采取措施改善涂裝小環境了,如開啟空調加溫和抽濕。

Excessive humidity will cause dew on the surface of the coating. Condensed water will destroy the curing agent and cause the phenomenon of whitening, losing light, sticking and Re-sticking of the coating, which will greatly reduce the decorative effect of the surface and cause rework in serious cases. Especially solvent-free topcoat, the surface drying time is generally longer. It is dangerous to paint in the rain immediately after painting or in the evening of winter and spring. But sometimes because the owner requests a time limit, ideal weather conditions are not easy to appear. At this time, measures need to be taken to improve the small environment of painting, such as opening air conditioning to warm and dehumidify.

溫度對于環氧地坪施工的影響:

The influence of temperature on epoxy floor construction:

地坪施工溫度應控制需在10-35℃范圍內,超出此范圍需采用特殊地坪涂料品種;地坪涂料(特別是面漆)涂裝與固化過程中(表干前),底材表面溫度應高于露點3℃以上,以防底材及濕膜表面水汽凝結影響涂層附著力和表面效果。

The construction temperature of floor should be controlled in the range of 10-35 C, and special floor coatings should be used when exceeding this range. In the process of coating and curing of floor coatings (especially topcoats) before surface drying, the surface temperature of the substrate should be higher than dew point 3 C, in order to prevent water vapor condensation on the surface of the substrate and wet film from affecting the adhesion and surface effect of the coating.

①夏季施工要求

Summer construction requirements

夏季在清晨或傍晚施工較為適宜。施工時需測量溫度,當氣溫超過35℃時,為了施工人員的健康和優質的涂膜質量,應避免施工。在濕度大和雨天施工,需測量相對濕度和露點溫度,隨時檢查已干燥涂膜的質量,當出現裂紋、橘皮、脫落等現象時,及時補涂維修。對于雙組分涂料,在配制稀釋劑和固化劑時應盡量采用慢揮發溶劑,混合甲乙組分時,采用少量、多次勤配的原則,防止出現涂料固化中放熱過快的現象而引起涂料報廢。溫度過高,雙組分涂料特別是無溶雙組分涂料易出現爆聚現象,即涂料反應過快,大量放熱而使涂料使用期縮短。高溫下施工時,雖然涂料干燥速率會較快,但即使測定已實干,也要按照一定的涂裝間隔進行下一道涂裝。

It is suitable to construct in the morning or evening in summer. Temperature should be measured during construction. When the temperature exceeds 35 C, construction should be avoided in order to improve the health of construction personnel and the quality of coating film. In wet and rainy days, it is necessary to measure relative humidity and dew point temperature, inspect the quality of the dried film at any time, and repair it in time when cracks, orange peel and peeling occur. For two-component coatings, slow volatile solvents should be used as far as possible in the preparation of diluents and curing agents. When mixing A and B components, the principle of a small amount and many times of diligent mixing should be adopted to prevent the phenomenon of excessive heat release in the curing of coatings from causing paint scrap. When the temperature is too high, two-component coatings, especially insoluble two-component coatings, are prone to explosion. That is to say, the reaction of coatings is too fast and a large amount of heat release shortens the service life of coatings. In high temperature construction, although the drying rate of the coating will be faster, the next coating should be carried out according to a certain painting interval even if the measurement is dry.

②冬季施工要求

(2) winter construction requirements

在有霧或被涂物表面蒙有水汽及霜雪時,不宜進行戶外施工。施工時被涂物表面溫度應高于露點3℃以上,氣溫不應低于涂料干燥規定的最低溫度。在10℃以下施工時,一般應在上午10點至下午3點作業,充分利用氣溫較高的時間,組織施工力量,盡快完工。盡量選擇專用型冬用固化涂料。涂料若過于粘稠不易涂裝時,可加入小于5%的揮發速率較快的溶劑,如丙酮、乙酸乙酯、乙酸丁酯等。可將涂料貯存在溫暖的環境中或用熱水、蒸汽加熱涂料(可能造成涂料質量的下降)。當溫熱涂料時,除非采用特別的涂料加熱設備,其溫度不要超過38℃。涂料閃點低于38℃時,加熱溫度不得超過其閃點。注意打開包裝桶蓋時,避免水汽的進入,嚴禁用明火或電火直接加熱,加熱時必須注意安全。與常規涂裝要求相比,在保證漆膜厚度的前提下,可適當增加涂裝道數,延長涂裝間隔。在測定涂膜實干后,再涂裝下一道涂料。

When there is fog or the surface of the coating is covered with water vapor and frost and snow, it is not suitable for outdoor construction. During construction, the surface temperature of the coating should be higher than dew point 3 C, and the temperature should not be lower than the minimum temperature prescribed by the drying of the coating. When construction is under 10 (?) C, it is generally necessary to work from 10 a.m. to 3 p.m. to make full use of the time when the temperature is high, organize the construction force and complete the work as soon as possible. As far as possible, select special winter curing coatings. If the paint is too thick and difficult to be coated, solvents with a faster volatilization rate of less than 5% can be added, such as acetone, ethyl acetate, butyl acetate, etc. Coatings can be stored in a warm environment or heated by hot water or steam (which may result in a decline in the quality of the paint). When a thermothermal coating is applied, the temperature shall not exceed 38 C unless a special coating heating device is used. When the flash point of the coating is below 38 C, the heating temperature shall not exceed its flash point. Pay attention to opening the lid of the packaging barrel, avoid water vapor entering, prohibit direct heating with open fire or electric fire, and pay attention to safety when heating. Compared with the conventional coating requirements, the number of coating paths can be increased and the coating interval can be prolonged on the premise of guaranteeing the film thickness. After testing the film dry, the next coat is applied.

為了充分保證環氧地坪施工質量。施工過程中還必須注意以下事項:

In order to fully guarantee the construction quality of epoxy floor. In the construction process, the following matters must be paid attention to:

1、施工環境搬運到施工現場的材料務必放在能夠避免風、雨以及直射陽光的地方。如陽光直接曬到施工面上,在基層中或還沒有完全硬化的涂膜里含有的空氣離子會因排出不暢而產生小氣孔,因此要用報紙或塑料布蓋住整個窗戶。為了防止風從外面吹人粉塵污染施工面,施工期間膜完全硬化期間應把門、窗、縫隙等透風處用護面膠帶封好。同時需防止縫隙吹來的風帶進塵土,注意不應在低于5℃的環境下施工,如有可能可開暖氣或空調,下雨時把敞開部分都關閉一避免潮氣影響施工面但不要阻礙通風。

1. Material transported to the construction site in the construction environment must be placed in a place where wind, rain and direct sunlight can be avoided. If the sunlight is directly exposed to the construction surface, the air ions contained in the basic layer or in the film which has not yet been completely hardened will cause small air holes due to poor discharge, so the whole window should be covered with newspapers or plastic sheets. In order to prevent the wind from blowing dust from the outside to pollute the construction face, during the construction period when the membrane is completely hardened, the ventilation areas such as doors, windows and crevices should be sealed with protective tape. At the same time, it is necessary to prevent the wind from blowing into the crevice from bringing dust. Attention should not be paid to the construction under the environment of less than 5 C. If possible, heating or air conditioning can be turned on. When it rains, the open part should be closed to avoid dampness affecting the construction surface, but do not hinder ventilation.

2、安全衛生管理方面的要求也很重要。從事施工的人員須經專門培訓,對化學產品有一定的知識;施工時須穿工作服、工作鞋、配勞防用品;各種材料不小心沾到皮膚上有時會損傷皮膚,盡快用肥皂清洗干凈,嚴重的送醫院救治;各種材料不準接觸任何水分(水性環氧地坪涂料除外),施工人員每人須帶擦汗用的毛巾,防止施工中汗水滴入地面或材料中;因環氧地坪材料中含微量的可燃物,施工現場嚴禁煙火,現場的材料不準放置在陽光直

2. Safety and health management requirements are also important. Personnel engaged in construction must be specially trained and have a certain knowledge of chemical products; during construction, they must wear work clothes, shoes and anti-labor articles; when various materials accidentally touch the skin, they sometimes damage the skin, clean it with soap as soon as possible, and send it to hospital for treatment seriously; and all kinds of materials are not allowed to touch any moisture (water ring). Except for oxygen floor coating, each worker should wear a towel to wipe sweat to prevent sweat from dripping into the ground or materials during construction; because epoxy floor material contains trace combustibles, fireworks are strictly prohibited at the construction site, and materials on the site are not allowed to be placed in direct sunlight.
