輥涂鋁卷形成缺陷與什么有關(guān)?

1、原材料
1. Raw materials
涂裝過程中較能影響涂裝質(zhì)量的因素是涂料和鋁卷,因為涂料的批次之間存在色差,涂料細度不夠而涂覆率不高,涂料與溶劑配合不佳、分層等等會直接影響涂裝效果而產(chǎn)生缺陷’鋁卷基材的不平整、膜厚不均勻、邊部撓曲度不佳等也直接影響產(chǎn)品質(zhì)量和整體使用。因此,對于原材料的選購,我們需相當謹慎嚴格。
The most influential factors in the coating process are coatings and aluminum rolls, because there are chromatic aberration between the batches, the coating fineness is not enough, the coating rate is not high, the compatibility of the coating and solvent, the delamination and so on will directly affect the coating effect and produce the defects' aluminum roll base material unevenness, film thickness uneven, side deflection. Poor and so on also directly affect product quality and overall use. Therefore, we need to be cautious and strict in choosing raw materials.
2、涂裝工藝
2. Coating process
涂裝工藝流程要嚴格規(guī)范,一旦某一環(huán)節(jié)出現(xiàn)差錯,則會造成鋁卷的缺陷。因此,要對涂裝輥、提漆輥、計量輥和基材相對線速比率控制在一定的范圍內(nèi)。要根據(jù)不同的體系和涂裝產(chǎn)品的膜厚,對涂料設(shè)定一定的粘度范圍,保證涂裝順利進行,促進產(chǎn)品質(zhì)量的提高。涂料的固化工藝, 烘箱控制必須按要求控制,不得任意變動,否則將嚴重影響涂裝質(zhì)量。
The coating process must be strictly regulated, and if there is a mistake in one link, it will cause defects in the aluminum coil. Therefore, it is necessary to control the relative speed ratio of coating roller, paint roller, metering roller and substrate in a certain range. According to different systems and film thickness of coating products, set a certain viscosity range for coatings, ensure smooth coating and improve product quality. The curing process of the coating and oven control must be controlled according to the requirements, and it must not be changed arbitrarily, otherwise, the quality of coating will be seriously affected.

3、涂裝設(shè)備
3. Coating equipment
涂裝設(shè)備要求運轉(zhuǎn)平穩(wěn),不能有橫、縱向抖動,涂裝輥要求研磨細膩。涂裝機所有輥子橫向跳動, 必須控制在允許范圍內(nèi),否則將嚴重影響涂層表面質(zhì)量。
The painting equipment requires smooth operation, no horizontal and vertical jitter, and the coating roller requires fine grinding. All rollers of the painting machine must be controlled within the allowable range, otherwise the surface quality of the coating will be seriously affected.
4、環(huán)境因素
4, environmental factors
要保持涂裝室內(nèi)部清潔干凈,做到防塵、防蟲和一定的通風性能,保證涂裝表面質(zhì)量不受污染。
Keep the paint room clean and clean, dust proof, insect proof and certain ventilation performance to ensure that the surface quality of the painting is not polluted.
5、人為因素
5, human factors
如果輥涂鋁卷的操作者經(jīng)驗欠佳,責任心低,則也會造成鋁卷形成缺陷。因此,要加強對操作者的培訓和讓操作者掌握涂裝技術(shù)的原理和要點,提升技術(shù)熟練程度和操作的規(guī)范性,加強責任性,嚴格按操作規(guī)程進行操作,以保證高質(zhì)量的涂裝產(chǎn)品。
If the operator who rolls the aluminum roll is not well experienced and the sense of responsibility is low, it will also cause the formation defect of the aluminum coil. Therefore, we should strengthen the training of the operator and the principle and key points for the operator to master the painting technology, improve the technical proficiency and the standardization of operation, strengthen the responsibility, and operate strictly according to the operating rules, so as to ensure the high quality of the coating product.
