KOYO bearing oscillation is very sensitive to bearing damage. For example, shedding, indentation, rust, crack, wear, etc. will be reflected in the bearing measurement of the bearing; therefore; by selecting a special bearing oscillation measuring device (frequency analyzer, etc.) It can measure the oscillating large. Deshi Zhizhi rewards the poor milling and milling. The measured value is different because of the bearing application conditions or the orientation of the sensor equipment; therefore, it is necessary to measure the value of each machine beforehand. After the analysis is aborted, the standard must be resolved.
The quality of the cage of the imported bearing is very good; but in the normal operation of KOYO bearing; incorrect operation will reduce the life of the bearing cage; even cause cracking. Here are the conditions for our analysis and analysis. Incured bearing cage cracking?
Top of the list: KOYO bearing cage abnormal load device is not in place, skew, excessive interference is easy to form clearance reduction; increase conflict heat generation; appearance softening; premature appearance of abnormal shedding; followed by the expansion of shedding; shedding foreign matter into the cage In the pocket; incurs the cage operation block and additional load; the wear of the cage is aggravated; the deterioration of the cycle effect; the cage crack can be formed.
Second: the problem of bearing smoothness is poor. The bearing operation is in a poor oil condition; it is easy to form Adhesive wear; the appearance of the work is deteriorated; the tearing material caused by adhesive wear is easy to enter the cage; the cage is subjected to an abnormal load; and the cage can be cracked. .
Third: KOYO bearings intrusion of hard foreign objects into the invasion of foreign hard objects; increased wear and abnormal load of the cage; also can cause cracks in the cage.
Fourth: bearing creep surface creep refers to the sliding appearance of the ferrule; in the case of lack of interference on the cooperation surface; the load point moves toward the surrounding direction due to sliding; the circumferential direction of the ferrule relative to the shaft or the casing occurs Violation of the appearance.
Fifth: KOYO bearing cage data defects, cracks, large foreign metal inclusions, shrinkage holes, air bubbles and riveting defects, lack of nails, pad nails or two-half cage contact surface; severe riveting, etc. can constitute cage cracking .

Dicyandiamide.Calcium cyanamide can be used as a pesticide intermediate

For many years the most important commercial process was via heating dicyanodiamide ([dicy"), either with ammonia or on its own, under pressure. The [dicy" is prepared by heating cyanamide solution at 70–80 °C. The cyanamide itself is prepared from calcium cyanamide:
Heated [dicy" to just above its melting point (209 °C) results in a vigorous exothermic reaction, producing some melamine and ammonia together with a number of complex water-insoluble deammoniation products:
In order to achieve a high yield of melamine in the commercial process, the reaction is carried out in the presence of ammonia at about 300 °C under pressure.
