Umunyu wa Sodium ya Acide Polyaspartic (PASP)

Intangiriro irambuye 

 

CAS No 181828-06-8，35608-40-6 Uburemere bwa molekile: 1000-5000

Inzira ya molekulari: C.₄H₅OYA₃M (C.₄H₄OYA₃M) m (C.₄H₄OYA₃M) nC₄H₄OYA₃M₂         

Imiterere yuburyo:

Ibyiza:

PASP ni ubwoko bwibikoresho bya biopolymer, muri molekile zirimo amido menshi ya amido, carboxyl nandi matsinda akora. Amido peptide ihuza ibikorwa byibinyabuzima hamwe n’imiti ihanitse, bigoye kubora ku bushyuhe bwinshi; itsinda rya carboxyl rirashobora kuba ingorabahizi hamwe nibyuma byinshi mumazi, bikora PASP kugira ibikorwa byinshi bya shimi mubisubizo byamazi; muri buri gice cyubatswe cya PASP, ogisijeni na azote irashobora gukora byoroshye guhuza hydrogène hamwe na molekile y'amazi, ifite hydrophilique nziza hamwe no gukomera kwamazi. Imiterere yihariye ya PASPiremeza ko ifite ubushobozi bwiza bwo gutatanya, kubuza kwangirika kwangirika, ibinyabuzima byangiza ibidukikije nibidukikije byangiza ibidukikije.

Ikoreshwa:

Ukurikije uburemere butandukanye bwa PASP, irashobora gukoreshwa mugutunganya amazi, ubuhinzi n’amashyamba, gukoresha peteroli, ibikoresho byogajuru hamwe n’indi mirima.

I. Gutunganya amazi

1. PASP has characteristic of polyanion surfactant, which can be chelated with magnesium, copper, iron, cobalt and other polyvalent metal ions after hydrolysis. It has excellent scale inhibition and dispersion properties. As scale and corrosion inhibitor, PASP is widely used in industrial circulating water, boiler water, reverse osmosis water, oil recycled water, desalination water treatment, especially for water treatment systems of high hardness, high alkalinity, high pH and high concentration.

2. PASP has good scale inhibition on CaCO₃, Urubanza₄, BaSO₄, Ca3 (PO₄)₂ , n'ibindi ..

3. PASP is an alternative of phosphor-containing Water Treatment Chemicals and has better scale inhibition effects. PASP can avoid eutrophication and second pollution in water system.

II. Ubuhinzi n’amashyamba

1. PASP can be used as fertilizer synergist in agriculture. Adding it into urea can improve fertilizer efficiency by 20-40% and reduce the fertilizer dosage;

2. Adding PASP in the production process for fertilizer can increase fertilizer granulation level, increase the number of standard particles to 97%, thereby enhancing the rate of finished products and reduce loss;

3. PASP can improve the nutrient absorption of grain, vegetable, melon and fruit, and flowers, promote root growth, increase crop yields, enhance plants and its stress resistance;

4. PASP can be used with phosphorodithioate and other pesticides to enhance pesticide effect, crop yields and improve crop quality;

5. PASP can form complex with heavy metals in the soil, displace heavy metals from the soil, in order to achieve the purpose of restoration of soil pollution.

III. Gukoresha peteroli

1. PASP can form chelation with calcium, magnesium, copper, iron and other metal ions to attach to the metal surface of the container to prevent metal corrosion. It is an excellent corrosion inhibitor, especially for preventing oil pipeline corrosion caused by carbon dioxide;

2. PASP with molecular weight around 10000 can reduce fluid viscosity. In bentonite mud, when the dosage of PASP is 0.4%, the viscosity reduction rate can be over 70%;

3. Ifite imbaraga zo kurwanya umunyu na calcium;

IV. Imiyoboro

1. PASP has characteristics of anionic surfactant and good chelation, dispersion properties. It can soften water, dispersing, anti-fouling, and prevent re-contamination of the greasy dirty off the clothes during the washing process;

2. Irashobora kwamamazwa hejuru yibyo kurya, ikarinda ibibyimba, bikavamo ingaruka nziza yo gukora isuku. Nibintu byingenzi bigize ibikoresho byo koza ibikoresho byo koza ahantu hakomeye;

V. Ibindi Porogaramu

Kuberako ikwirakwira neza kuri comporganic organique na organic, PASP has been applied with different degree in pharmaceuticals, pigments, paints, leather, inorganic chemicals, oilfield chemicals and other fields.PASP is called "third-generation polyurea", it can be used to produce protective coatings of high weather resistance, high resistance to chemical corrosion, fast-curing paint, and applied directly to fast curing coatings on the metal substrate and industrial flooring, etc., ; it can be used in the tanning process as tanning agents, produces biodegradable leather; pharmaceutical carrier material made from PASPhas been widely used in family planning, anti-tumor drugs making etc.

Amapaki n'ububiko:

200L ingoma ya plastike, IBC (1000L), ibyo abakiriya bakeneye. Kubika amezi icumi mucyumba cyijimye kandi ahantu humye.

Kurinda umutekano:

PASP ni alkaline, witondere kurinda umurimo mugihe ukora, irinde guhura nuruhu, amaso, nibindi, kwoza amazi menshi nyuma yo guhura.
