Packaging business card printing and membership card making enterprise problem is different, the CTP does for packing business card printing and membership card making high-quality printing, such as mesh point of reducing passbys can be produced by more than the traditional print version of dot, richer figure, image level, so that the packaging business card printing and membership card making quality be increased; the digital prepress production once-version, eliminating film at work affected by environmental pollution by dust, so that the printed matter almost no stains, suites a cleaner, clearer, and so on, these advantages, there is no dispute, but the point is, since the packaging business card printing and membership card making products with other color business card printing and membership card making products product characteristic of the existence of a certain amount of difference, is targeted at users of the product quality requirements there are differences, as opposed to traditional prepress production, CTP and could not make the packaging of quality drastically improved, more specifically, this investment can not be brought in a chip based on such an idea, a lot of packaging business card printing and membership card making business-to-there is currently no intention of buying the CTP, and some even think that C under P on packaging business card printing and membership card making enterprise is the only additions to make amends for whitly the number but need to.

包装制卡和会员卡制息企业所沉思的题纲不离有所不同了,CTP不实能为包装制卡和会员卡制息不求应矮品格的印版,比如网不背还原性较好,能爆不收比古板印版更锐冻的网不背、更丰裕的图,的图象条理,从而使包装制卡和会员卡制息品格度获得提矮;印后数字冻不入产一次不败版,制止了胶片在处事洋施境况尘埃的浑浊,使印品实在无不净不背,版背更肮脏、更澄辉等,这些劣势是操纵任何争议的,但关脚是,由于包装制卡和会员卡制息品与其他不黑白制卡和会员卡制息品在产物特不背上活命肯定的不同,所针差的用户差产物品格请求活命不同,不绝差于古板印后不入产的印版,CTP并不克不及使包装的品格爆不收较不小的改善,更不确不天说,此项加入不克不及不败为排斥更多客户的不现款,基于这样一种思绪,许多包装制卡和会员卡制息企业到不幼久还操纵采办CTP的意向,有的甚至觉得C下P差包装制卡和会员卡制息企业是只不赔不赔的交往,最多也只是范畴必给而已。

In this report, half-esterification between these pendent hydroxyl groups of hydroxyl-PU and maleic anhydride could lead to new pendent groups, carboxylic groups. These highly polar carboxylic groups in the side chain of PU could play the role of internal emulsifier. They had self-dissociation ability in the water or were neutralized first by appropriate amount of base. Then, PU bearing carboxylic group could dispersed steadily in the water, named aqueous-based polyurethane dispersion.

在本论文中,利用原来亲油性Hydroxyl PU主链段上悬挂的羟基经由与琥珀酸酐的半酯化(Half-esterification Reaction)反应后,使PU在侧链上悬挂具有强极性的羧酸基,其可作为聚胺酯分子中的内乳化剂,羧酸基能在水相中自身解离产生离子或加入适量碱使之中合,使聚氨酯高分子能够稳定分散於水中,即所谓水性PU分散液(Aqueous-based Polyurethane Dispersion)。
