Export storage of vegetable storage methods?? Prosthetic storage

October 31, 2024

The roots are harvested after the vegetables are grown, and they are planted in suitable places so that they are kept at a certain low temperature and high humidity conditions to maintain their slow growth and metabolic activity. In this state, the growth of vegetables is inhibited, the consumption of nutrients is less, and the roots can absorb a small amount of minerals and water in the soil, so that their metabolism can be well maintained. Therefore, it can maintain the freshness and disease resistance of vegetables for a long period of time. This storage method is called pseudo-storage, and it is used more for storage in North China. It is mostly used for celery, cabbage, wobble shoots, cauliflower and other vegetables. In North China, it is not too cold in winter, and it is more likely to be planted with impotence or ditch. In the colder areas, the well-preserved cellar is used for the prosthesis.
When the raw vegetables are harvested, retain the intact roots, remove the diseased, yellow, and old leaves, arrange closely in rows and rows, and cultivate the soil in the roots, and bury the roots in the soil. According to climate changes, cover the grass on the vegetables to prevent freezing. When using the cellar planting, pay attention to ventilation and control the temperature.
The management of vegetable prosthetics is mainly to give a cold and cold environment. Avoid high temperatures in the early stages and prevent freezing in the later stages.
Curing Agent
â… Product Composition: polydadmac

â…¡ Product Properties

The appearance of this product is colorless to pale yellow viscous liquid. It is soluble in water. It has goodhydrolytic stability and high adaptability to PH value changes. It`s safe and non-toxic. Its freezing point is about -2.8â„ƒ, specific gravity is about 1.04/cm3 and decomposition temperature is 280-300â„ƒ. It`s polymeride AKD maturing agent of high charge density. Emulsion provides strong cationic component promotive and protective agent and promotes curing effect. This product is added directly into the synthesis process of intermediates or added a certain ratio in emulsion. This product can be added more in the papermaking system with heavier anionic trash, as the pulp potential equilibrium to play a dual role of sizing enhancement and forcing ripening.

III. Quality indicators;

Appearance: colorless to faint yellow thick liquid Solid content: 40Â±1%

PH value: 4.0~7.0 viscosity (mpa.s, 25â„ƒ): 7000-12000

IV. Application:

This product is applied in alkaline sizing system of AKD (Alkyl Ketene Dimer) to restrict largely the hydrolysis and migration aptitude of AKD. [The third generation" AKD is mainly used for the making of multipurpose duplicating paper filled by precipitated calcium carbonate. 60% cationic polymer can adhere to the fiber after the paper containing cationic polymer being reused, by which enhance hydrophobicity of the paper. Added to waste paper deinking agent, its cationic hydrophilic group adheres to ink particles easily, especially for hydrophobic aniline ink. After flotation, the whiteness of pulp increased. This product is also applied as cationic surfactant in pitch control agent for pulping.
