The invention discloses a special plasticizer TM8 for automobile interior parts. Raw materials and auxiliary materials of the plasticizer TM8 comprise acid anhydride, alcohol, a catalyst, sodium carbonate and a filter aid. A process of the special plasticizer TM8 for the automobile interior parts comprises esterification, purification and filter press purification, and molecular distillation (short-path distillation). In esterification, alcohol is added first, after the temperature of a reactor is less than 80DEG C, 1,2,4-benzeneticarboxylic anhydride is added, then the catalyst is added, whenthe temperature of the material rises to 220DEG C, a negative pressure reaction starts, when an acid value is less than or equal to 0.1mgKOH / g, flash evaporation and dealcoholization start. In purification, steam stripping is performed while temperature rises to 215+ / -10DEG C, and the filter aid diatomite is added so as to purify and stir. In molecular distillation, the vacuum degree reaches lessthan 100pa, and the material inlet temperature is maintained at 215+ / -5DEG C. The raw materials are easy to obtain, the process is advanced, the equipment is simple, the plasticizer is environmentally friendly, has high plasticizing efficiency, resists high and low temperature, has low volatility, has small odor, and is highly stable.

The invention provides a micro-miniature under-pressure pluggable fluid connector. The micro-miniature under-pressure pluggable fluid connector comprises a plug and a socket. The plug comprises a plugshell and a sealing assembly. The sealing assembly comprises a sleeve and a sealing block. A locating sleeve is arranged at the rear end of the plug shell. The locating sleeve abuts against the sleeve through a first spring. The inner wall of the front end of the plug shell is provided with a first limiting part. A first seal ring is arranged between the sealing block and the plug shell. The socket comprises a socket shell and a sealing rod assembled in the socket shell. The sealing rod is sleeved with a second spring and a sealing ring. The front end of the second spring abuts against the sealing ring, and the rear end of the second spring abuts against the sealing rod. The inner wall of the front end of the socket shell is provided with a second limiting part. The inner side of the sealing ring and the sealing rod form sealing through a second seal ring. The front end of the sealing rod is provided with a plurality of through holes. During operation of the micro-miniature under-pressure pluggable fluid connector, no any seal ring is exposed in fluid, so that the seal rings are prevented from being washed away; and moreover, through the special sealing assembly, the stability ofthe connector is improved, the flow resistance of fluid is reduced, and the fluid flux is increased.

The invention discloses a sprouting vegetable culturing method, belonging to the technical field of vegetable cultivating. The sprouting vegetable culturing method comprises the following steps: (1) seed selection: picking out injured seeds, and culturing uninjured seeds; (2) seeding: paving a matrix in a mesh disc, and flatly paving to-be-cultured seeds on the matrix; (3) buffing: wetting the seeds with mist, and keeping the seeds wet until budding; (4) growth: introducing flowing water from the lower part of the mesh disc, and enabling the water surface to be in contact with buds of the seeds until the buds grow to a harvesting height, wherein the seeds are not soaked in water; and (5) harvesting: harvesting the sprouting vegetables by cutting from the roots of the buds. The sprouting vegetable culturing method has the advantages that the operation is simple, the cost is low, and the cultured sprouting vegetables are healthy and free of pollution. The sprouting vegetable culturing method is particularly suitable for culturing the sprouting vegetables in families.
