环氧地坪漆塗料使用單位在產品塗裝過程中,防靜電地坪漆的施工技術指標一般都很重視對环氧地坪漆塗層的各項質量指標的檢測,而通常忽視對环氧地坪漆塗料質量的檢測。塗裝前,嚴格控制選擇使用环氧地坪漆塗料的質量,才能保證產品塗裝的高質量。批量塗料購用進廠,工藝部門隻能對塗料抽樣檢測合格驗收,取樣檢測,雖具該批塗料代表性的質量性能,但不能保證整批塗料100%的完全合乎塗料標準,以及出廠質量標準指標的各項性能要求:
In the process of product painting, the construction technical index of anti-static floor paint generally attaches great importance to the detection of various quality indexes of floor paint coatings, but usually neglects the detection of the quality of floor paint coatings. Before painting, the quality of epoxy floor paint should be strictly controlled to ensure the high quality of products. Batch coatings purchased and used in the factory, the process department can only sample and test the qualified acceptance, sampling test, although the batch of coatings representative of the quality performance, but can not guarantee that 100% of the whole batch of coatings fully meet the paint standards, as well as factory quality standards indicators of various performance requirements: (1)环氧地坪漆塗料粘度的檢測塗料粘度分為相對粘度,運動粘度和絕對粘度。塗裝過程中,生產現場常用塗-4粘度計測得的塗料粘度,即為相對粘度。粘度檢測除常用的塗-4粘度計外,還有檢測高粘度的塗-1粘度計、落球粘度計和應用較少的旋轉粘度計等。
(1) Testing the viscosity of epoxy floor coatings The viscosity of the coatings is divided into relative viscosity, kinematic viscosity and absolute viscosity. In the process of coating, the viscosity of coating measured by -4 viscometer is the relative viscosity. Viscosity testing in addition to the commonly used coating-4 viscometer, there are high viscosity testing coating-1 viscometer, drop ball viscometer and less application of rotary viscometer.
(2)地坪漆塗料細度的檢測顏色塗料組分中的顏料、填料顆粒的粗細大小,以及在生產中均勻分散的程度,對塗膜外觀平整光滑,光澤等有較大的影響。為此,必須測試塗料細度的質量指標,使之符合塗料質量標準規定的指標。常用刮板細度計可檢測塗料的細度指標。
(2) Testing the fineness of floor coatings; the size of pigments and filler particles in the components of color coatings, and the degree of uniform dispersion in production, have a greater impact on the smooth appearance and gloss of the coatings. For this reason, the quality index of coating fineness must be tested to conform to the specifications specified in the paint quality standard. The scraper fineness gauge can be used to detect the fineness index of the coating.
(3)常用塗料質量標準和出廠質量標準塗料質量(指溶劑塗料)有國際標準,我國有國傢標準、化學工業部部頒標準和各生產廠的出廠質量標準。地坪漆塗料質量標準中可側定的有塗料的細度、粘度、流平性、遮蓋力、密度、閃點、稠度等項目,使用前對地坪漆塗料還有一此可日測的質量項目。
(3) There are international standards for the quality of commonly used coatings and for the quality of coatings (referring to solvent coatings) as well as national standards, standards issued by the Ministry of Chemical Industry and quality standards for each factory. In the quality standard of floor paint, there are such items as fineness, viscosity, leveling, covering power, density, flash point and consistency of the coating. There is also a quality item that can be measured daily before use.
施工环氧地坪漆和地坪翻新固然他們的選材和施工基本一樣,但是他們的方式也不盡相同的,地坪翻新起首要將舊地坪鏟除,並做底層處理。
Epoxy floor paint and floor renovation although their selection of materials and construction is basically the same, but they are not the same way, the floor renovation will be the first to remove the old floor, and do the underlying treatment.
鏟除舊塗膜,首先要搞清楚地坪老化的狀況和新地坪漆可否相容,假如地坪老化水平嚴峻,則可以用水浸泡、沖刷再用油灰刀整理幹凈。普通運用機械辦法清理溶劑型地坪,例如鋼絲刷或電動砂輪,由於溶劑型地坪漆外表比較致密,所以運用機械法比較適宜。
To eradicate the old coatings, the first thing to do is to make clear the aging state of the floor and the compatibility of the new floor paint. If the aging level of the floor is severe, you can use water immersion, scouring and then finishing with a putty knife. Ordinary use of mechanical methods to clean solvent-based floor, such as wire brushes or electric grindi彩色沥清地坪ng wheels, because the surface of solvent-based floor paint is more compact, so the use of mechanical method is more appropriate.
假如由於公司開展緣由需求更新地坪,首要需要考慮的是坪漆的相容性。假如地坪相容性好,隻需求清洗外表再進行地坪塗裝便可,假如相容很差,則需求將舊地坪清理後再重裝。
If the company needs to update the floor for the reason, the first thing to consider is the compatibility of Ping lacquer. If the compatibility of the floor is good, just need to clean the surface and then coat the floor can be, if the compatibility is very poor, then the need to clean up the old floor after reinstallation.
环氧防靜電地坪漆具有裝飾性和適用性,然而在施工完成後常會呈現塗膜氣泡、刷痕、空鼓、脫皮等現象,這些問題主要有幾個原因,基本是由於施工欠妥形成,也可能是選擇瞭劣質資料形成,或許是在運用進程中沒有保護。
Epoxy anti-static floor paint has decorative and applicability, however, after the completion of the construction often appear film bubble, brush marks, empty drum, peeling and other phenomena, these problems are mainly due to the formation of inappropriate construction, may be the choice o透水地坪f inferior data formation, perhaps in the process of application is not protected.
环氧樹脂地坪漆塗料在交聯固化成膜中產生的內應力較低:环氧地坪漆塗料在成膜過程中,功能性地坪漆的技術施工事項很多因素都會導致地坪漆的塗膜內應力的產生而造成塗膜的最終缺陷,尤其是塗膜對底材附著力的降低。环氧樹脂分子中含有仲輕基固化時還會派生出一些經基,輕基之間將產生氫鍵締合作用使环氧樹脂分子排列緊密,因此环氧樹脂在固化前後密度差別較小,而且环氧樹脂的固化反應主要是逐步開环的加成聚合反應,在反應中無小分子的副產物生成,因此环氧樹脂的固化收縮率很低,因此环氧樹脂塗料在固化成膜時對塗膜/界面之間的附著力影響很小。
The internal stress of epoxy floor coatings is low in the course of cross-linking and curing. During the process of film formation, many factors in the technical application of functional floor coatings will lead to the internal stress of the coatings and cause the final defects of the coatings, especially the reduction of adhesion of the coatings to the substrate. When the epoxy resin molecule contains the secondary light group, it also derives some meridian groups. The hydrogen bond association between the light groups makes the epoxy resin molecule arrange tightly. Therefore, the density difference of the epoxy resin before and after curing is small. Moreover, the curing reaction of the epoxy resin is mainly the addition polymerization of the gradual ring opening, and there is no such reaction. As a by-product of small molecules, the curing shrinkage of epoxy resin is very low, so the adhesion between the film and the interface is little affected by the curing of epoxy resin coatings.
