Trikresyl phosphate (TCP)

♦ Introduzzjoni qasira

Tricresyl phosphate is a mixture of three organophosphate isomers .In general ,

it is colorless and transparent oily liquid .It can dissolve in Toluene ,Methylene

chloride ,Methyl ethyl ketone ,Methanol ,insoluble in water

♦ Applikazzjoni

This product is an important flame retardant plasticizer for vinyl resin and nitrocellulose ,

used in the paint film can increase the flexibility, it has excellent intermiscibility,

used in synthetic rubber, PVC, polyester, polyolefin and soft polyurethane foam plastics

as flame retardants. This product can give high polymer good abrasion resistance,

weatherability, mildew resistance, radiation resistance and electric properties.

Can also be used as a gasoline additive, lubricating oil additive and hydraulic oil

♦ Main production process

Mixed cresol reacts with phosphorus trichloride to produce tricresyl phosphite,

which then reacts with chlorine to produce tricresyl phosphate dichloride, which

is then hydrolyzed to obtain tricresyl phosphate.

♦ Ippakkjar u Ħażna

Pakkett: Once the TCP has been produced and refined, it is packaged into

suitable containers, such as Galvanized drums(200kg or 230kg)

Ħażna: Aħżen f'temperatura tal-kamra, Bogħod mid-dawl tax-xemx dirett

♦ Proċess ta 'spezzjoni

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

other main properties.

2. Spezzjoni ta 'tmigħ: The principle of raw material feeding is first-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: According to customer’s requirement, third party inspection can be

carried out on the products before shipment.

♦ Metodu ta' Spezzjoni
