記不清哪位名人曾經說過這么一句話：一件事物的存在，必然有它的合理性和必要性。清潔液也是這樣的道理。
Can't remember which famous person once said such a sentence: the existence of a thing, must have its rationality and necessity. Cleaning liquid is also such a reason.
從一開始，各墨水廠家在給印刷濟南圍擋的用戶提供產品的時候，就包括了與墨水配套使用的"供墨系統的清算專家"－－清洗液。之所以說到配套，是因為各種墨水的主要成份及消費工藝是不盡相同的，也就需要與各自相匹配的清洗液，這里主要說的是清洗液對各自配套墨水的溶解功能。這也標明不是哪種溶劑對一切墨水的溶解功能都是很好的，當然也包括丙酮和丁酮。
From the beginning, the ink manufacturers in the printing of Ji'nan Wai block users to provide products, including the use of ink and supporting the "ink system for the liquidation of experts" - cleaning fluid. The reason is because when it comes to supporting the main ingredients and process all kinds of ink consumption is not the same, it needs cleaning liquid matched with each other, here that is dissolved in the cleaning fluid to the respective function matching ink. This also shows that the function is not the kind of solvent to dissolve all the ink is very good, including acetone and butanone.
說這些主要是看到如今有一部分客戶在清潔噴頭時用從市場上買來的丙酮或丁酮，而清潔作用并不像想象的那么明顯，然后抱怨墨水把噴頭堵得洗不開了，其實是你的方法沒用對。丙酮和丁酮的確有很強的溶解性，因為溶劑墨水中的顏料是被渙散劑經過鍵與鍵的聯系構成渙散能力的，過強的溶劑會損壞這種平衡，形成顏料渙散的不穩定，發生沉積，最終阻塞噴頭。
These mainly see now some customers from the market to buy the acetone or butanone in the cleaning nozzle, and the cleaning effect is not as imagined so obvious, then complain about the nozzle blocking ink wash off, is useless for your way. The solubility of acetone and butanone is very strong, because the pigment is solvent ink dispersing agent after the keys and key links constitute lax ability, strong solvent will damage the balance, the formation of pigment and lax instability occurred in deposition, eventually blocking sprinklers.
另外，噴頭的構造很復雜，出廠的噴頭有一些部位是用膠粘劑密封的，膠是有機物，大部分的膠是不耐酮酯醇類有機溶劑的，當然也包括噴頭上的密封膠。最好的耐溶劑膠也有極少量地被溶劑溶解和溶脹。噴繪墨水及清洗液是經過大量實驗被證明對噴頭影響最小，假如簡單地在市面買來丙酮或丁酮兌到墨水中，當然對噴頭的傷害也就更大。假如它們的清洗效果要好于清洗液的話，眾廠家們何苦費力、費錢的去研制清洗液呢？
In addition, the nozzle structure is very complex, there are some parts of the factory of the nozzle is sealed with adhesive, glue is organic, most of the glue is not resistant to alcohol ketone ester in organic solvents, including nozzle sealant. The best solvent resistance also has a very small amount of solvent to dissolve and swell. Printing ink and cleaning solution is proved through experiments with minimal impact on the nozzle, if simply to buy acetone or butanone against to ink in the market, of course, on the nozzle do more harm. If the cleaning effect is better than the cleaning liquid, all manufacturers are laborious and costly why to develop the cleaning liquid?
