ordinary ordinary ordinary Price of about 300 or so, the
hot air gun is mainly temperature instability, high and low, air volume and
instability. The scale of the air pressure gun just adjust the size of its
power, so the temperature of raw slowly when the phone is switched on, for
several minutes, and then temperature soared, a little attention will burn out.
Such as amplifiers, CPU, circuit boards, etc. It also has a temperature
detection, it seems only to high temperature protection, adjust the temperature
and unreal. Suggest you not to save money, and often compensate machine.
standard standard standard About after the price, this kind of heat gun
calibration is used to adjust the temperature of the real, warming faster when
the phone is switched on, a few seconds can be reached, and the temperature will
not increase, in close range adjustment, air volume is more stable, applicable
repair mobile phone, I use the air pressure gun is very good, such as: 3508 CPU
won't burn out in more than 90%. Digital temperature display type The basic

Causes and Solutions of Cucumber Bitter Melon
Cucumber plants, including melons, all have bitter tastes. Absolutely no bitter varieties are not yet available. However, when bitterness is evident, it affects quality. The practical experience in recent years has summarized the causes of the bitter taste of cucumber and the solutions. 1, the cause of the bitter taste of cucumber Cucumber bitter, first of all have a certain relationship with the species, the general dark green leaf color varieties than lighter leaf varieties are more prone to bitter melon, such as improper cultivation will increase the appearance of bitter melon. 1.1 Excessive application of nitrogen fertilizer. Due to the excessive amount of nitrogen fertilizer, the plants are too long. When the melons are not neat, the melons on the side branches and weak branches tend to have a bitter taste. 1.2 melons grow slowly. During periods of low temperature and low sunshine, especially on continuous cloudy days, when the roots or activities of cucumber are damaged or hampered, less water and nutrients are absorbed, and the melon strips grow slowly, often accumulating more bittersin in roots and lower melons. 1.3 bitter taste melons caused by high temperatures. Cucumbers cultivated in winter and spring, entering the late spring high temperature period, or due to the aging of the plant roots, or due to excessive soil moisture, the root absorption capacity weakened, weak assimilation, and nighttime humidity is too high, melon strips grow slowly, in the melon There are more bittersin accumulated in the strips, thus forming bitter melons. 2. Measure to solve cucumber bitter melons 2.1 Adopt sunlight greenhouse with good heat preservation performance; 2.2 Scientific fertilization, especially not excessive nitrogen fertilizer application; 2.3 Planting density should not be too large, open row spacing, reduce number of plants, improve strains Intercropping conditions; 2.4 When the plants enter into senescence, promote the hormones that occur in the roots through cooling, water control, and irrigation, and rejuvenate them early; enter the high-temperature period, the management temperature should not be high, especially to prevent the night temperature is too high, at the same time Watering should not be too large. It was found that bitter melons appeared. The cucumbers were plucked and then soaked in clean water overnight to reduce the bitter taste of the melons.
