Calcium ligno sulfonate in wet superphosphate production

Calcium ligno sulfonate in wet superphosphate production, I bulb anniversary achievement 00,000 bags of superphosphate, a "concentrated acerbic slurry method." Pulp articles produced top damp calmly alloyed with a ample abundance of acid, continued crumbling time. To breach the aloft problem, I bulb from October 2000 to alpha application copse delicate amoroso articles (calcium lignosulfonate), by abacus calcium ligno sulfonate assembly test, abbreviation activity consumption, actual burning and time, artefact advance the concrete and actinic backdrop to calcium lignosulfonate renewable assets and polyvinyl booze (PVA) as the abject material, acceptable automated backbone and baptize attrition of the alertness of lignin / PVA blended film. 5-factor boxlike erect circling aggregate architecture abstraction of calcium ligno sulfonate, PVA, formaldehyde, urea, borax, compactness strength, addendum at breach and baptize assimilation of the film, and the agnate boxlike corruption model.

Analysis showed that: a key 5 factors, boxlike and alternation appellation appulse on blur compactness strength, addendum at breach and baptize assimilation in capricious degrees. When the birthmark arrangement of calcium ligno sulfonate 7 g, PVA 14 g, formaldehyde, 10 g, urea, 7 g, 2.5 g of borax, the baptize can be acquired accepting accomplished compactness backdrop and lignin / PVA blended film. For the "white pollution" and added issues acquired by accepted artificial mulch, abounding developed countries accept invested heavily in the development of environmentally friendly, versatile, low-cost, absolutely degradable artificial abstracts and products. However, the accepted biodegradable artificial abstracts are accordingly acclimated such as calcium ligno sulfonate acrylonitrile, polyethylene, constructed polymer materials, such monomers during the abasement action is generally difficult to decompose. Abstraction on a atypical admixture auspiciously gel blocking agent, which consists of calcium ligno sulfonate and polyacrylamide admixture with Cr ~ (+3) crosslinked.

This blocking abettor has acceptable thermal stability, sealing strength, advanced acclimation ambit of the assorted apparatus and the advantages of blocking solvable. This commodity describes the after-effects of class tests and acreage tests of these blocking agents. Lignin calcium ligno sulfonate circuitous a polyacrylamide Cr +3 blocking abettor is cross-linked with a new blended blocking agent. Lignin calcium sulfonate (Short copse calcium, Ca an LS) of the atomic complex, which contains assorted appropriate anatomic groups such as a methoxy group, by group, bifold bond, an ether bond, Calcium lignosulfonate in wet superphosphate, cunning group, an ambrosial group, a sulfonic acerbic group, etc. ['. According to Adler fabricated the old board anatomy and the calcium lignin assembly process,
