研究了UV固化皮革涂饰剂的光引发剂、光活性单体、助剂与皮革力学性能及表观性能的关系,并对皮革表面微观性能及透气度进行了表征。
The results showed that the brightness of the hand-sheets decreased with increasing dosage of SDS;and the tensile strength of hand-sheets increased first with increasing charge of SDS,then decreased;however,the tearing strength of the hand-sheets decreased first with the increasing dosage of SDS and then increased;the air permeability of the hand-sheets reached maximum at a certain dosa.
研究表明,纸页的白度随非离子瓜尔胶浓度的增加而降低;抗张强度先随非离子瓜尔胶添加量的增大而增大其后随之下降;撕裂度先随非离子瓜尔胶用量的升高而下降其后随之提高;透气度先随非离子瓜尔胶用量的升高而增加达到一个峰值后又降低。
