低溫容器板在生產(chǎn)過程中影響其質(zhì)量因素的原因多種多樣,不僅要加強施工人員的培訓(xùn)在原材料選擇和質(zhì)檢上也要下足功夫。原材料在影響防腐涂層質(zhì)量中占主要因素,其中 膠粘劑、環(huán)氧粉末、聚乙烯、是影響低溫容器板質(zhì)量關(guān)鍵因素之一。
Low temperature container plate in the production process of the factors affecting the quality of a variety of reasons, not only to strengthen the training of construction personnel in the selection of raw materials and quality control will also have enough time. The raw materials are the main factors affecting the quality of the coating. The adhesive, epoxy powder and polyethylene are the key factors to influence the quality of the low temperature container.
一旦原材料中存在質(zhì)量問題鋼板就會出現(xiàn)如涂層表面麻點、氣泡、防腐涂層厚度不均勻、涂層表面有水擊點、皺 褶、粘接強度低、翹邊等現(xiàn)象。 因此在原材料膠粘劑、聚乙烯的選擇和進(jìn)場后應(yīng)做好復(fù)檢和防腐層材料的適用性實驗,膠粘劑檢測其粘接強度,聚乙烯看其表面是否光滑,性能不達(dá)標(biāo)的產(chǎn)品一律淘汰。
Once the raw material quality problems of steel plate will appear as coating surface pitting, bubbles, anti-corrosion coating uneven thickness, coating the surface of water hammer, wrinkles, low bonding strength, edge warping phenomenon. So in the choice of raw material and adhesive polyethylene after should do the re examination and coating materials for experiment, detection of the adhesive bonding strength of polyethylene, the surface is smooth, the performance of substandard products will be eliminated.
在低溫容器板進(jìn)場后 應(yīng)看其表面是否有坑洼、油污、口徑的圓度、焊縫高度,只有做好低溫容器板表面的處理工作才能更好的增加防腐層的附著力。只要在施工前做好原材料的質(zhì)檢工作,即能保證合格率又能避 免資源浪費,一旦出現(xiàn)返工的情況有可能會劃傷防腐涂層,這樣會企業(yè)造成不必要的經(jīng)濟損失。
In the low-temperature container plate approach should be to see whether there is oil, surface potholes, diameter roundness, weld height, only do the cryogenic vessel plate surface treatment can increase the coating adhesion. As long as the good raw material in the construction of the quality inspection work, to ensure the qualified rate and can avoid the waste of resources, once the rework situation may scratch coating, such enterprises will cause unnecessary economic losses.
