from Baidu library patent type:
Utility Model
application (patent) number:
CN201921444535.2
date of application:
20190902
public/announcement number:
CN210936292U
date of publication/announcement:
20200707
Applicant (patentee):
Renqiu Zhenhua Anticorrosive Materials Co., Ltd.
Inventor:
national and provincial code:
CN130982
Summary:
The utility model discloses an auxiliary device for wood preservation and oil immersion, which includes a cylinder, a cleaning mechanism and a disassembly mechanism. The cleaning mechanism is located on the outer surface of the cylinder. The cleaning mechanism includes a fixed column. Both ends of the rear surface of the fixed column are fixedly connected with fixing rods, the rear surface of the cylinder is provided with a ball screw, and both ends of the outer surface of the ball screw are provided with fixing sleeves; the cleaning rod, fixed column, collar, ball screw and cleaning cotton installed on the outer surface of the cylinder body are designed to facilitate cleaning of the upper surface of the cylinder body. The bevel gear B is driven to rotate by the motor, and the bevel gear B drives the bevel gear A to rotate, so that the bevel gear A drives the ball screw to rotate. At this time, the collar on the ball screw will move to one side, thereby driving the cleaning rod, the cleaning cotton on the cleaning rod wipes the upper surface of the cylinder well to clear

Creosote,woodtarfraction - Determination of oil in wood preservative industrial wastewater-UV spectrophotometry
From VIP Journal Professional Edition
Author:
Summary:
P> due to the complexity of petroleum components, its determination methods are more, and a certain determination method can only determine some of the components, so when choosing the determination method, it is necessary to understand the main components of the specimen, in order to determine the more suitable determination method for the specimen. China's railway wood preservative is based on heavy oil 60 ~# and anthracene oil as anticorrosive oil agents, which have characteristic absorption in the ultraviolet region, so the oil in anticorrosive industrial wastewater is determined by ultraviolet spectrophotometry. This method is simple and fast, and the minimum detection concentration iskeywords:
