Method for afforesting wall surfaces and side slopes with climbing-vine curtain wall

InactiveCN101779562AMeet growthMeet the actual needs of coverageWallsExcavationsGrowth plantEngineering
The invention discloses a method for afforesting wall surfaces and side slopes with climbing-vine curtain wall, which comprises the following steps: (1) seed selection of plants: the plants having the climbing and hanging growth properties are selected; (2) planting containers are set: the planting containers are established according to the real situation and construction requirement of the slope surface; (3) filling of planting soil: the cured and finely-broken farming soil is filled; (4) supporting net racks are established and woven; (5) planting of plants: the plants having the climbing and hanging growth properties are planted with the traditional method; (6) later-period management: watering and fertilizer application are immediately carried out; (7) prevention of injurious insects: pesticide and germicide are sprayed. The method has the following advantages that the curtain wall supporting net racks are added, so the growth of the plant vines which climb upwards can be ensured to stay at a mighty state; the nutrition supply is required to be coordinated with the plant growth; the nature of the plants is satisfied through the order coordination and scientific guidance; the later-period management of the plant is fine; and the perennation permanent-green woody Leguminosae is used, so the afforesting coverage rate is improved, the source of the plants is vast, the choice is multiple, and the construction technical method is simple and convenient.

Modified rubber masterbatch, and rubber composition and vulcanized rubber produced therefrom, and the preparation processes for them

The present application relates to a modified rubber masterbatch and preparation method thereof, rubber composition prepared therewith and vulcanized rubber and preparation method thereof. The modified rubber component comprises uncrosslinked rubber and rubber particles having crosslinked structure dispersed therein, wherein the rubber particles having crosslinked structure are synthetic rubber particles and/or natural rubber particles, have an average particle size of 20-500 nm and a gel content of 60% by weight or higher, and wherein the uncrosslinked rubber is styrene-butadiene rubber. The weight ratio of the rubber particles having crosslinked structure to the uncrosslinked rubber is greater than 20:80 and less than or equal to 80:20. The rubber composition comprises a blend of modified rubber component and base rubber, in which the modified rubber masterbatch is present in an amount of 1 to 70 parts by weight, relative to per 100 parts by weight of the base rubber. The vulcanized rubber of the rubber composition has not only low rolling resistance and excellent wet skid resistance, but also excellent wear resistance, and thus can be used for producing high performance tread rubber.

Purification method for deep dehydration and impurity removal of olefin by full-temperature range adsorptive extraction

InactiveCN107774083ASolve the difficulty of desorptionBig roomEthylene productionHydrocarbon oils refiningChemistryAfter treatment
The invention discloses a purification method for deep dehydration and impurity removal of olefin by full-temperature range adsorptive extraction. The purification method is characterized in that crude olefin feed gas (liquid) enters a gas/liquid phase adsorption process, an extraction and desorption process and an extracting agent regeneration process sequentially, moisture and trace impurity components are absorbed by an absorbing agent, and an olefin product with a purity of more than or equal to 99.9-99.99 percent (v/v) flows out from the top of an adsorption tower; after the adsorption process is completed, an extracting agent is introduced into the adsorption tower for the extraction and desorption process to dissolve out the moisture and the trace impurity components. Extraction anddesorption gas enters the extracting agent regeneration process, and the extracting agent is recovered and recycled after treatment. The purification method disclosed by the invention has the benefits that by adopting an adsorption-extraction and desorption process and in combination with an adsorption mechanism and an extraction and desorption dissolving mechanism, the whole operation process ismore stable and safer, the energy consumption is low, the product purity is high, the equipment investment cost is low, the purity of the olefin product is more than or equal to 99.9-99.99 percent, and the yield is more than or equal to 99 percent.
