我們對氫氧化鉀并不陌生,工業(yè)氫氧化鉀是行業(yè)常用的一類產(chǎn)品。由于涉及到這類產(chǎn)品,其粘度引起了很多人的關(guān)注。有人認為粘度和質(zhì)量密切相關(guān)。他們之間有聯(lián)系。粘度越高,質(zhì)量越好,但真的是這樣嗎?下面就和小編一起去詳細看看吧。
We are no stranger to potassium hydroxide. Industrial potassium hydroxide is a kind of product commonly used in the industry. The viscosity of this kind of products has attracted a lot of attention. Some people think that viscosity is closely related to quality. There is a connection between them. The higher the viscosity, the better the quality, but is this really the case? Now let's take a detailed look with Xiaobian.
粘度是指在濃度和溫度下的粘度。工業(yè)氫氧化鉀必須有粘度。但并不是說工業(yè)氫氧化鉀的粘度越高,分子量就越高,質(zhì)量就越好。事實上,一般沒有辦法提高已經(jīng)生產(chǎn)出來的工業(yè)氫氧化鉀的粘度,要么加入交聯(lián)劑,使其部分支化或交聯(lián),改變其流體力學,將其粘度提高到一定程度。
Viscosity refers to the viscosity at concentration and temperature. Industrial potassium hydroxide must have viscosity. However, it does not mean that the higher the viscosity of industrial potassium hydroxide, the higher the molecular weight and the better the quality. In fact, there is generally no way to improve the viscosity of industrial potassium hydroxide that has been produced. Either add crosslinking agent to partially branch or crosslink it, change its hydrodynamics, and increase its viscosity to a certain extent.
提高工業(yè)氫氧化鉀的直接方法是提高聚合物的程度,提高其分子量。另一種方法是清洗時加入增塑劑、成核劑等,可以提高工業(yè)氫氧化鉀的結(jié)晶度,從而提高產(chǎn)品的粘度。但是這種方法是不可取的,因為這種處理不會降低成本,反而會增加成本,所以只能作為增稠劑使用,比如可以用于熏香行業(yè)。分子量越高,實際效果越好。
The direct way to improve industrial potassium hydroxide is to increase the degree of polymer and its molecular weight. Another method is to add plasticizer and nucleating agent during cleaning, which can improve the crystallinity of industrial potassium hydroxide and improve the viscosity of the product. But this method is not desirable, because this treatment will not reduce the cost, but will increase the cost, so it can only be used as a thickener, such as for the incense industry. The higher the molecular weight, the better the actual effect.
粘度和質(zhì)量之間沒有關(guān)系。并不是說高粘度的質(zhì)量會更好。我們在選擇的時候,應該選擇正確的方法,比如從這一方面來選擇:
There is no relationship between viscosity and quality. It's not that the quality of high viscosity will be better. When we choose, we should choose the right method, for example, from this aspect:
常溫下不具有腐蝕性,但在高溫和應力下會對很多金屬造成嚴重腐蝕。不同溫度下不同濃度溶液的設備和管道選材不一,KOH溶液的濃度為0~30%。如果溫度低于50℃,用一類材料制造的設備和管道通常耐腐蝕;而0%~30%的溶液在50~100℃時對二類材料制成的設備和管道有較好的耐腐蝕性。
It is not corrosive at room temperature, but it will cause serious corrosion to many metals under high temperature and stress. The materials of equipment and pipelines with different concentrations of sodium hydroxide solution at different temperatures are different, and the concentration of sodium hydroxide solution is 0~30%. If the temperature is lower than 50 ℃, equipment and pipelines made of class I materials are usually corrosion-resistant; While 0% – 30% sodium hydroxide solution has good corrosion resistance to equipment and pipelines made of class II materials at 50-100 ℃.
