Method for increasing tender bud cutting and rooting rate of catalpa bungei in mode of removing terminal buds of cutting slips

InactiveCN103621306AEasy to drainSolve the problem of susceptible bacteriaHorticultureCatalpa bungeiBiology
The invention relates to a method for increasing the tender bud cutting and rooting rate of catalpa bungei in a mode of removing terminal buds of cutting slips. The method is characterized by comprising the following steps: selecting three-year to four-year strong branches of catalpa bungei in March, and cutting into 30-40cm shoot segments for sand storage; when the height of newly-germinated tender buds in a sand bed reaches 10-15cm, removing the terminals of the tender buds; after ten days, taking down the tender buds with heels as cutting slips; after cutting off half of leaves on the cutting slips, soaking roots into 75% alcohol for disinfection for 30 seconds, then soaking into 3000mg.L<-1> IBA (Indole Butyric Acid) for 60 seconds, and finally inserting the cutting slips into a seedling-raising disk; inserting one cutting slip into each hole cup with the depth to be 1/2-1/3 of the length of the cutting slip; after cutting, using a 85% shade net to cover for sun block, and using an automatic spray device to spray for supplying water; and hardening seedlings for 10-15 days and then planting after entering the seedling hardening period, namely 70 days after cutting. The survival rate of catalpa bungei tender buds cut by the method can reach more than 80 percent, and the popularization and application of catalpa bungei are greatly promoted.

Dehydrating barrel stopping mechanism used for washing machine and washing machine

ActiveCN107740250ABlocking rotationThe blocking effect is stable and reliableOther washing machinesTextiles and paperEngineeringMechanical engineering
The invention discloses a dehydrating barrel stopping mechanism used for a washing machine and the washing machine. The dehydrating barrel stopping mechanism used for the washing machine comprises a first stopping structure, a second stopping structure, a first gear set and a first driving device; the first stopping structure is suitable for being arranged on a dehydrating barrel of the washing machine, the second stopping structure comprises a stopping bar which can move between a stopping position and a releasing position, the stopping bar stops on the side of the first stopping structure along the periphery of the dehydrating barrel when in the stopping position and allows the first stopping structure to cross the stopping bar along the periphery of the dehydrating barrel when in the releasing position, the first gear set is in transmission connection with the stopping bar, the first driving device is in transmission connection with the first gear set and drives the stopping bar tomove between the stopping position and the releasing position through the first gear set. According to the dehydrating barrel stopping mechanism used for the washing machine, rotation of the dehydrating barrel can be stopped, and the stopping effect is stable and reliable.

Roofing materials made with nylon fiber composites

Synthetic nylon fiber composite materials having embossed or molded surfaces that emulate shingles or roofing tiles are disclosed, for providing waterproof, high-strength, durable substitute for shingles or roofing tiles. In one embodiment, these materials can be relatively thin, and designed to rest on supporting sheets of plywood, oriented strand board (OSB), or nylon fiber composite board that have been nailed to rafters. In an alternate embodiment, these materials can be manufactured in sheets with sufficient thickness, stiffness, and strength to allow them to be nailed directly to rafters, thereby eliminating the need for a supporting layer of plywood or OSB. In a third embodiment, these materials can be molded or embossed to emulate Spanish tiles, or to provide enhanced drainage or other useful traits. For improved waterproofing, the lower edge of each segment can be provided with an overhang that will overlap the upper edge of an adjacent sheet on the next lower horizontal row, to provide overlapping material at each juncture between these composite segments. These materials also can be coated or embedded with chemicals that provide increased resistance to water, fire, and ultraviolet damage. They provide excellent thermal insulation, and can reduce heating and air conditioning costs. A preferred manufacturing process uses needle-punched fiber mats, and any combination of nylon-6 and nylon-6,6 fibers can be used.

Adhesive filling and grinding processing method for stator-rotor iron core component of motor

InactiveCN101895176ASolve the problem of inner and outer conicityIncreased resistance to deformationManufacturing stator/rotor bodiesAdhesiveRoom temperature
The invention discloses an adhesive filling and grinding method for a stator-rotor iron core component of a motor. The method comprises the processes of gluing the iron core component through lamination, grinding an iron core by a benchwork, filling an adhesive, removing adhesive layers on two end faces by the benchwork, grinding an inner hole and an excircle of the iron core by a grinder, removing a potting adhesive and the like. The method is characterized in that: when the adhesive is filled, the potting adhesive is placed into a container, stirred and heated to a temperature of between 120 and 130 DEG C; the potting adhesive is poured into an pre-heated iron core groove immediately; a die is vacuumized in a vacuum chamber, so that bubbles are removed from the die, wherein the vacuum degree is 10 to 300Pa and the time is 5 to 20 minutes; and the die is taken out and cooled at the room temperature, so that the potting adhesive is solidified. Compared with the prior art, a profiled groove part of the stator-rotor iron core component forms an entity through the adhesive filling process so that deformation resistance of the stator-rotor iron core component is enhanced and interrupted cut is avoided; and at the same time, the grinding process solves the problems of crack, swelling, poor coaxiality and the like caused by internal and external conicity of the stator-rotor iron core component and temperature distortion of the adhesive layers of the iron core component.
