Dibutil fosfat （dbp）

♦ Introduzzjoni qasira

Dibutil fosfat (DBP) is an organic compound . It is a clear,

colorless liquid that is soluble in organic solvents like ethanol

and ether.

♦ Applikazzjoni

1. Solvent: Dibutyl phosphate is used as a solvent in different applications,

including extraction processes, industrial cleaning, and as a reaction

medium in various chemical reactions.

2. Plastiċizzant: Dibutyl phosphate acts as a plasticizer, which means it

is added to plastics and resins to improve their flexibility, durability,

and processing characteristics. It helps to enhance the flow and

workability of the materials during manufacturing processes.

3. Ritardant tal-Fjammi: Dibutyl phosphate is used as a flame retardant additive

in plastics, coatings, and textiles. It helps to reduce the flammability

and improve the fire resistance properties of these materials.

4. Extraction Agent: Dibutyl phosphate is used as an extraction agent in

various processes, such as the separation and purification of metals, particularly

uranium. It effectively extracts uranium from ores and solutions during

the uranium mining and nuclear fuel production industries.

♦ Ippakkjar u Ħażna

Pakkett: Once the DBP has been produced and refined, huwa ppakkjat fi

kontenituri xierqa, such as Plastic Barrels or IBC drum.

Ħażna: If stored correctly and kept in the original sealed container, the product

has a shelf life of at least 24 months. Stainless steel and glass equipment

components as well as plastics such as polyethylene and polytetrafluoroethylene (PTFE)

have proven suitable. Materials suitable for sealing are polytetrafluoroethylene (PTFE)

and graphite. Ordinary steel is unsuitable because it reacts with dibutyl phosphate,

resulting in the formation of hydrogen.

♦ Proċess ta 'spezzjoni

1. Spezzjoni deħlin: Il-materja prima ewlenija, huma spezzjonati għall-kontenut tagħhom, dehra u

proprjetajiet ewlenin oħra.

2. Spezzjoni ta 'tmigħ: Il-prinċipju tal-għalf tal-materja prima huwa l-ewwel in-first-out, u d-dehra

tal-materja prima prinċipali hija spezzjonata bl-addoċċ skond jekk hemmx bidla kbira fil-

kondizzjonijiet ta 'ħażna qabel l-għalf.

3. Teħid ta 'kampjuni tal-lott fil-proċess tal-produzzjoni: Matul il-proċess tal-produzzjoni, l-indiċi ewlenin ta

kull lott ta 'prodotti: il-kontenut u l-valur tal-aċidu se jiġu eżaminati tliet darbiet f'perjodi ta 'żmien differenti.

4. Spezzjoni tal-Ħażna: Kull lott (10 tunnellati) jiġi spezzjonat qabel il-ħażna.

5. Spezzjoni 'l barra: Skond il-kwantità mitluba mill-klijenti, il-prodotti se jkunu

kampjun u spezzjonat.

6. Spezzjoni qabel il-ġarr: Skond il-ħtieġa tal-klijent, spezzjoni ta 'parti terza tista' tkun

mwettqa fuq il-prodotti qabel il-ġarr.
