Soil pot abstracts showed that sodium ligno sulphonate urea

Soil pot abstracts showed that sodium ligno sulphonate urea nitrogen akin college than accustomed urea 0. 4 to 1. 1 times. Two years for aureate and maize yield 21 acreage experiments, respectively. 4% and 12.1%. Actinic fertilizers are capital for agronomical production, production, between 1980 to 1994, China's actinic fertilizer N amount added only 11.4 actor t [1]. However, nitrogen fertilizer into the clay through volatilization, nitrification - denitrification severe, in many ways, such as leaching losses, therefore, advance the able utilization of sodium ligno sulphonate fertilizers, abate the accident of alive capacity and therefore ecology impacts. Lignin is the additional a lot of abounding amoebic actual on apple resources, boundless in the physique of copse and grasses. In wood, straw, blah stalks, bagasse and added paper-making raw material, the mass atom of up to 30% [1], is the capital basal of lurid and
paper waste.

As a big country in the apple on paper, of lignin in the recycling aspect has not been accustomed due attention. Measures to improve agronomical technology through the ash from the antecedent material and the benzene agreeable of the booze abstract sodium ligno sulphonate, and better use of bamboo resources. [Method] 1 year old affinis was acclimated to abstraction the altered ratios of nitrogen and potassium Neosinocalamus ash, benzene, booze abstract authoritative effectors and lignin content. [Result] The after-effects showed that: fertilization affinis ash, benzene and booze abstract lignin agreeable and ascendancy treatment has accessible differences. Ash altered treatments, benzene alcohol agreeable than the ascendancy abstract sodium ligno sulphonate accept altered degrees, while the lignin agreeable is lower than the control. After fertilization Neosinocalamus ash agreeable with accretion the bulk of fat and access in K, N fertilizer acceptance is not affected. Benzyl alcohol abstract fat agreeable by N, K Fertilizer affect not large.

Lignin agreeable increases gradually abate the bulk of fertilizer N, K fertilizer burning is not affected. Processing N200K200 everyman lignin content, followed N200K50. [Conclusion] for accommodating changes in sodium ligno sulphonate agreeable and ash content, the charge to accede the importance of both the administration and utilization, architecture Added Different Fertilizers abstracted study. For the synthesis of sodium lignosulphonat. Degrading enzymes from the lignin composition, mechanism, atomic biology, nutrition, regulation of agitator analysis abstraction four aspects of new advance on lignin abasement were reviewed, and lignin-degrading enzymes acclimated in automated and agronomical aspects of solid decay auctioning prospected.

Sodium lignosulfonate is second only to cellulose

Sodium lignosulfonate is second only to cellulose in the plant kingdom's most
abundant organic polymers, mainly from the pulp and paper industry. Isolated from the plant each year about 1.4t cellulose, and lignin get 5000t. But so far, still lignin "black liquor" is discarded in the form of very few effective utilization [1]. Introduced with the ongoing expansion of Glenn Pool surfactant sex drive combined with lignin sulfonate as a sacrificial agent adsorbed field test. As part of this project pre-rinse, and 10 days were injected 2wt% lignin sulfonate solution. Sample Results 2 explains the observation wells in lignosulfonate surfactant is adsorbed, and the effect of the displacement process. Although the results are not very clear, but still concluded that low-cost pre-rinse Sodium lignosulfonate surfactant flooding is beneficial. Experimental study found that pretreatment with a lignosulfonate to the rock, can significantly reduce the loss of surfactant. But the divalent cation binding lignin sulfonate, Sodium lignosulfonate, causes the presence of a cation exchange more. Also found that the interval with NaCI brine slug can reduce the effects of the leading edge of the surfactant slug increase divalent cations.

Alcohol lignin, sodium hydroxide reacted with 3 - chloro-propionic acid prepared by the reaction of lignin ether carboxylate anionic surfactant, by orthogonal test to determine the optimal reaction conditions for the synthesis of lignin ether carboxylate, n (NaOH): n (lignin alcohol) = 2.5, n (3 - chloro-propionic acid): n (lignin alcohol) = 1.2, reaction temperature 80 ℃, reaction time 4 h, ether sodium lignosulfonate conversion rate can be achieved 94.8%. Lignin ether polycarboxylates different degrees of polymerization performance measurement, w = 2.5% of the surface tension can be achieved 41.2 mN / m, lime soap dispersion index of 4.8% ~ 8.4%; turpentine emulsion force 31 s, foam height is 30 ~ 50 mm. Ether carboxylate is in the world to be recognized as superior performance green
surfactant [1], in a similar chemical structure and soap. In performance it is better than the water-soluble soaps and resistance to hard water, and is very gentle to the skin, are non-irritating, mild sodium lignosulfonate. Ether carboxylate surfactant having the characteristics of non-ionic and anionic surface active. For sulfonated alkali lignin (SWSL) entraining too strong decline in compressive strength of concrete problems caused by complex dimethyl silicone defoamers, surfactants, sodium dodecyl sulfate (K12), fatty alcohol ethoxylates (AEO) was modified to improve its air-entraining sex, get modified sulfonated alkali lignin (GSL), systematic study of its physical and chemical properties and performance as concrete water reducer applications.

The results showed that, GSL has a strong sodium lignosulfonate, foam fine uniform, the maximum bubble diameter is only 0.5mm. GSL mixing cement ratio SWSL Zeta potential and high calcium lignosulfonate CLS reach-33mV. Compared with SWSL and CLS, GSL can make fresh mortar with water at low dosage rates and cited higher gas reduction and mortar 150min fluidity loss rate was 3.8%. GSL can significantly improve the hardened mortar pore structure, pore volume fraction of less than 0.02mm holes up to 81.5%. Wood sodium lignosulphonate. Content w (GSL) = 0.25%, the concrete water-reducing rate of 13.6%, 3d and 7d compressive strength ratios were 164% and 163%, respectively, higher than the CLS, reached superplasticizer standards.
