Cleaning
Agent:
The difference between organic cleaning
agent and inorganic Cleaning Agent simply, cleaning agent cleaning agent is
made of organic compounds containing carbon, cleaning agent made of inorganic
compounds, cleaning agent is not containing carbon, therefore they belong to
the inorganic. Classification method of cleaning agent is also a lot of
countries are not the same, we usually divided into water, half water, non
water cleaning agent three categories.
How
to select a good cleaning agent:
The chemical stability, not easy to be
cleaned and reacts; the surface tension and viscosity, strong penetration; the
low boiling point, can be dry; there's no flash point, non flammable; the KB
value should not be too high, not miscible with the material to be washed; the
low toxicity, safe use; and non ODS and low GWP value (global warming
potential), and environmental protection.
Application
Requirement:
For chemical industrial cleaning, should
meet the following requirements.
The cleaning agent used for cleaning
purposes and different cleaning objects, can be emphasized or choice for these
requirements. The dirt cleaning speed, dissolving dirt thoroughly. The cleaning
agent itself has a strong reaction to the dirt, dispersed or dissolved
scavenging capacity and in the limited time, can thoroughly remove dirt. The
cleaning of the object damage should be in production license limits, and
corresponding control measures for corrosion of metals may cause. The cleaning
agent is cheap and easy to get, set foot on the localization; low cleaning
cost, does not cause too much the consumption of resources. The cleaning agent
on the biological and environmental non-toxic or low toxicity, the generated
gas, waste water and waste residue, should be able to be disposed to comply
with relevant state regulations. The cleaning condition is mild, try not to
depend on the force of export The strengthening conditions, such as
temperature, pressure, mechanical energy and does not require excessive
requirements. Such as the cleaning process in the cleaning surface of the
object remains insoluble, does not produce new stain, do not form a new harmful
to the subsequent process of covering layer, does not affect the quality of the
products. It does not affect the bubble and smell the cleaning process and
on-site health.

A summary of the handheld weather station and its main functions
The hand-held weather station is an agroforestry microclimate collection system. It is used for on-the-spot monitoring of wind conditions, wind speed, rainfall, air temperature, relative humidity, atmospheric pressure, solar radiation, soil temperature, soil moisture and other nine meteorological elements. , Through a variety of communication methods (wired, digital radio, GPRS mobile communications, etc.), and the Meteorological Center computer communication, meteorological data will be transmitted to the meteorological center computer meteorological database for statistical analysis and processing.
The operational function of the hand-held weather station is real-time monitoring of nine meteorological parameters such as wind speed, wind direction, rainfall, temperature, humidity, air pressure, solar radiation, soil temperature, soil moisture, etc. The microcomputer meteorological data collector has meteorological data collection, real-time clock, and timing. Storage, parameter settings, parameters, and meteorological history data are protected against power down.
However, its hardware features cannot be ignored. There are many types of automatic weather stations, their structures are basically the same, mainly composed of sensors, collectors, system power supplies, communication interfaces and peripheral devices (computers, printers, etc.). The device or device in which the sensor can sense the change of the measured meteorological element and convert it into a usable output signal according to a certain rule is usually composed of a sensitive element and a converter.
