如何防止無錫環氧地坪涂料發生沉淀、結塊

標簽:無錫環氧地坪 | 無錫環氧地坪公司

我們在進行環氧地坪漆涂裝施工的時候,時常會發現我們購買回來的無錫環氧地坪涂料出現了沉淀或者是結塊的現象,難道這是因為我們被騙了而買到了劣質的環氧地坪漆涂料產品了嗎?其實不是的,這是因為涂料內成分自然下沉。這次我們來教大家如何防止環氧地坪涂料發生沉淀、結塊的現象。

When we are painting epoxy floor paint, we often find that the epoxy floor paint we bought has precipitated or caked. Is this because we were deceived and bought inferior epoxy floor paint products? In fact, it is not because the composition of the paint naturally sinks. This time we are going to teach you how to prevent the precipitation and caking of epoxy floor coatings. 1、在設計涂料配方時,考慮適合的顏基比。一般顏基比不要超過2∶1,特殊品種除外。顏填料盡量選用密度小些的,有些顏料如紅丹粉、鉻黃、云母氧化鐵、鐵紅、沉淀硫酸鋇等,密度都較大,少用或酌情用,低密度顏填料替代。

1. When designing the formulation of coatings, the appropriate ratio of pigment to base should be considered. Generally, the ratio of pigment to base should not exceed 2:1, except for special varieties. Pigments and fillers should be selected with lower density as far as possible. Some pigments, such as red powder, chrome yellow, mica iron oxide, iron red, precipitated barium sulfate, etc., have higher density and should be replaced by low density pigments and fillers. 

2、涂料的粘度不能過低,選用的顏填料之間不能相互反應。如鋅粉、鋁粉、氧化鉀等比較活潑,在貯存穩定性不佳涂料中盡量不用或分罐包裝。在涂料生產時,采用適合的設備,盡量研磨分散均勻,達到規定粘度、細度。例如氯化橡膠類涂料,穩定性差,易與鐵類物質發生反應,應用不銹鋼或石襯里設備生產。

2. The viscosity of coatings should not be too low, and the selected pigments and fillers should not react with each other. For example, zinc powder, aluminium powder, potassium oxide and so on are more active, and they should not be used or packed separately in coatings with poor storage stability. In the production of coatings, appropriate equipment should be used to grind and disperse evenly, so as to achieve the prescribed viscosity and fineness. For example, chlorinated rubber coatings, poor stability, easy to react with iron, using stainless steel or stone lining equipment production. 

3、在涂料中加入防沉劑,利用少量助劑的特殊性能,制成觸變性涂料,改變涂料懸浮狀態。常用的防沉劑有硬脂酸系列、氣相二氧化硅、改性膨潤土、氫化蓖麻油等。現進口防沉劑品種很多,一般加入0.1%-0.5%,就可防沉淀,而加入2%-3%,就可將涂料制成觸變性涂料,形成較高的膜厚。

3. Thixotropic coatings are prepared by adding anti-settling agents into the coatings and using the special properties of a small amount of additives to change the suspension state of the coatings. The common anti-sedimentation agents are stearic acid series, gas phase silicon dioxide, modified bentonite, hydrogenated castor oil and so on. At present, there are many kinds of imported anti-settling agents, generally adding 0.1% - 0.5%, can prevent precipitation, and adding 2% - 3%, can be made into thixotropic coatings, forming a higher film thickness. 

經銷商的防治措施。1、涂料貯存應放置在陰涼通風處,定期將涂料桶橫放、倒置或搖動幾次。要注意涂料的貯存期限,先入庫的先使用。對于一些貯存期限低的涂料,如氯化橡膠、氯乙烯、聚氨酯類要特別小心。

Preventive measures for dealers. 1. Coatings should be stored in a cool and ventilated place, and paint barrels should be placed horizontally, inverted or shaken several times regularly. Attention should be paid to the storage period of coatings, first put into storage, first use. For some coatings with low storage life, such as chlorinated rubber, vinyl chloride and polyurethane, special care should be taken. 

2、對于已沉淀的涂料,可用手工或機械攪拌均勻后再使用。對于結塊現象,應先把可流動部分倒出,用刮鏟從容器底部鏟起沉淀,研碎后,再把流動介質倒回原先桶中,充分混合。

2. For the deposited coatings, they can be uniformly stirred manually or mechanically before being used. For the caking phenomenon, the movable part should be poured out first, and the sediment should be shoveled from the bottom of the container with a scraper. After crushing, the flowing medium should be poured back into the original barrel for full mixing.
