In recent years, hydrocarbon cleaning has
become increasingly popular among users, and its attention in the market has
also risen. For users who are already using hydrocarbon cleaning, the
advantages of hydrocarbon cleaning are very significant, and when meeting the
cleaning requirements, enterprises no longer need to worry about sewage
discharge, occupational disease hazards and inspection by environmental
protection departments; For some users who are still waiting, on the premise of
meeting the cleaning requirements, they may consider more about the
environmental protection and safety of hydrocarbon cleaning. So, in order to
let you know more about hydrocarbon cleaning, we will explain its environmental
protection and safety aspects. Hydrocarbon cleaners are used in a wide range of
applications in industrial production, such as machining, electronics
manufacturing, and automotive maintenance. It can clean all kinds of metal
products, plastic parts, electronic components, etc., and can quickly and
thoroughly remove dirt, improving production efficiency and product quality.
What is a hydrocarbon cleaner? Hydrocarbon cleaner is a hydrocarbon composed of carbon and hydrogen, commonly known as hydrocarbon, mainly composed of saturated alkane solvents, the carbon atoms in the molecule are connected by single bonds, and the rest of the valence bonds are combined with hydrogen to form a compound, the general formula is CnH2n + 2. Its chemical structure is stable and does not react with most substances, such as strong acids, strong bases, strong oxidants, etc. Since it is an inert solvent, does not ionize H ions, and is not miscible with water, the hydrocarbon cleaner does not have any corrosive effect on metal substances and is chemically extremely stable. Hydrocarbon cleaner is an organic solvent cleaner with carbon and hydrogen as the main components. In terms of chemical structure, it is mainly composed of hydrocarbons such as alkanes and olefins. These hydrocarbons have unique physical and chemical properties that make them excellent cleaning agents. In terms of physical properties, hydrocarbon cleaners usually have low viscosity and surface tension, which allows it to penetrate well into the inside of dirt and stains, dissolve and peel off, at the same time, its boiling point is relatively moderate, it is not volatile at room temperature, it is easy to store and use, and it is also easier to volatilize off after use, leaving no residue.
Comparison of hydrocarbon cleaning agent
with other cleaning agents Secondly, there are two main reasons why hydrocarbon
is an environmentally friendly cleaning solvent: first, compared with
traditional water-based cleaning agents, hydrocarbon cleaning has no sewage
discharge, waste liquid treatment is simple, VOCs emission meets national
standards, and can be recycled through distillation, as shown in Figure 1
below;
Nature Water-based cleaning agent
Hydrocarbon cleaning agent Volatile Slow volatilization, long drying time, high
energy consumption Depending on the volatility, you can choose a hydrocarbon
cleaning agent with fast volatilization Corrosiveness Has a certain corrosive
effect on active metals Does not corrode metal materials Oil-soluble Good
solubility to non-fatty stains Good solubility to fatty and oil stains Waste
liquid and waste gas treatment High cost of waste liquid and waste gas
treatment Qualified enterprises recycle waste liquid, which is simple and fast;
VOCs emissions meet national standards Recycling Usually not recycled in
industry Distillation and recycling on the other hand, compared with
halogenated hydrocarbon cleaning solvents, hydrocarbon cleaning is non-toxic,
has no occupational disease hazards to the human body, does not have a damaging
effect on the ozone layer, and meets the requirements of national environmental
protection policies, as shown in Figure 2 below;
Focusing on the safety of hydrocarbons,
safety is very important in industrial production, and with the continuous
enhancement of people's safety awareness, the importance of safety has also
increased accordingly. Due to the flammable properties of hydrocarbon, some
users are discouraged, and even "talk about hydrogen discoloration".
Definition of Security What is security? In
the theory of system security, security means that there is no danger, no
threat, no harm, no loss, which is a relative concept. This theory emphasizes
that there is no such thing as absolute safety in the world, and that safety is
relative to danger, and that there is no danger or loss caused, and that it is
relatively safe. In other words, hydrocarbon cleaners are relatively safe as
long as they do not cause accidental damage.
The "four elements" of the
accident system involve four elements, namely: the unsafe behavior of people
(Men), the unsafe state of the machine (Machine), the poor environmental
(Medium) factors, and the management measures are not in place, which is often
called the "4M" element.
Two. About hydrocarbon cleaning agents, 90%
of people have asked these questions In terms of chemical properties,
hydrocarbon cleaning agents have good solubility and can effectively remove
various organic dirt such as oil, grease, wax stains, etc. It can have a
physical or chemical reaction with these dirts to disperse and dissolve in the
cleaning agent, so as to achieve the purpose of cleaning. Moreover, the
hydrocarbon cleaning agent is relatively stable and does not react easily with
other substances, reducing the risk of corrosion to the items to be cleaned.
<!--[if !supportLists]-->1.<!--[endif]-->Can
hydrocarbon cleaners replace trichloroethylene? The answer is: Yes. Due to its
strong cleaning ability and low cost, trichloroethylene used to be the
preferred cleaning agent for many enterprises, but because of its own great
harm to the environment and human health, coupled with the strict requirements
of export customers for products that must meet their environmental protection
standards, it was gradually eliminated by enterprises, and enterprises began to
pay attention to more environmentally friendly hydrocarbon cleaning agents.
<!--[if !supportLists]-->2.<!--[endif]-->Can
hydrocarbon cleaners wash stretch oil? Yes, hydrocarbon cleaners are non-polar
petroleum fractions with most lubricating oils, anti-rust oils, machining oils,
and drawing oils, and hydrocarbon cleaners are more effective at cleaning these
mineral oils than halogenated hydrocarbons and water-based cleaners according
to the principle of similar miscibility.
<!--[if !supportLists]-->3.<!--[endif]-->Can
hydrocarbon cleaners replace wax remover? Yes, some brands have developed a
special hydrocarbon cleaning agent for wax removal in the vacuum coating and
water plating industry, which can completely replace the wax removal water with
the latest improved and adjusted cleaning process.
<!--[if !supportLists]-->4.<!--[endif]-->Can
hydrocarbon cleaners be mixed with water? Hydrocarbon cleaners are
solvent-based cleaners and belong to non-polar cleaners, while water is polar
solvents and they are not miscible. Therefore, when using hydrocarbon cleaning
agent for cleaning, it cannot be mixed with water, and it can be cleaned
directly with the original solution. Moreover, hydrocarbon cleaners are very
pure refined solvents, and the products can be completely volatilized after
drying without any residue.
<!--[if !supportLists]-->5.<!--[endif]-->Can
hydrocarbon cleaners be brushed by hand? Yes, but you must wear gloves designed
for industrial cleaning to protect your hands from injury. Generally speaking,
the combination of ultrasonic cleaners or vacuum cleaners can make the cleaning
quality better and more efficient. The specific choice of cleaning process
should be determined by combining the shape and size of the workpiece to be
cleaned, the nature of the oil stain and the original cleaning process.
<!--[if !supportLists]-->6.<!--[endif]-->Can
hydrocarbon cleaner solve the problem of yellowing of white copper cleaning? It
can solve the problem of yellowing of white copper after cleaning, and the use
of hydrocarbon cleaning agent can improve the cleaning quality. It is
recommended not to directly touch the workpiece with your hands during the
processing process (special gloves can be worn), and produce in accordance with
scientific specifications to avoid fingerprint residue. Compared to some
traditional cleaners, hydrocarbon cleaners have environmental advantages. The
volatile gas it emits during use has less pollution to the atmospheric
environment and meets the requirements of modern environmental protection. In
addition, after proper treatment, hydrocarbon cleaners can be recycled, reducing
the cost of use.
In conclusion, hydrocarbon cleaners play an
important role in the cleaning field due to their unique physical and chemical
properties, and are highly efficient and environmentally friendly cleaning
agents.
