One, not saturated colophony

Colophony of not saturated polyester is the solution of the high polymer polymer that be reacted by acid and mellow condensation polymerization and becomes. The content of the styrene that serves as solvent among them is 20%-40% about.

Colophony of not saturated polyester belongs to 3 kinds of dangerous chemical

Its exterior is liquid of colorless or small yellow

Main harm sex has:

1. Can light

2. Inspiratory and ill health, can stimulate eye and skin

3. Have a harm to the environment

The main harm composition of solution of colophony of not saturated polyester

1. Styrene (solvent) :

Flash point 31 degrees, 3.3 kinds of Gao Shan nod combustible liquid, the weight per cent in solution of colophony of not saturated polyester is 20%-40% about

2. Acetone (a few colophony of partial gel coat is medium containing) :

Flash point - 18 degrees, 3.1 kinds of Gao Shan nod combustible liquid, the weight per cent in colophony of partial gel coat is 0%-5% about

Resinous of not saturated polyester endangers a gender one- - light it is dangerous to explode

1, colophony of not saturated polyester is combustible, its steam and air can form volatile mixture, encounter bright fire, high fever to have combustion explosion risk.

2, the 3 element that pose be on fire and explosive risk: Source of fuel, oxygen, ignition

3, how to control exercise process to be lighted mediumly explode risk

1. Control ignition source

2. Avoid working site to form flammability explosion gas

4, in how controlling exercise process light explode source of ignition of risk — control

1. Working site is forbidden smoke.

2. Be far from kindling, heat source

3. Control get angry works

5, how to control exercise process to be lighted mediumly explode risk — avoids working site to form —— of flammability explosion gas we should avoid combustion mixture from beginning to end form or exist.

1. Use airtight system as far as possible, do not use ringent tray, container or collect implement the material that will contain low flash point

2. Gather through what ventilated take a breath will prevent to be able to burn gas

Lighter than air gas gathers in roof;

Heavier than air gas spreads in the ground and gather in small part;

3. Should instantly any leak wipe up or use absorb material

6, put out a fire

When once send,giving birth to fire, use powder, carbon dioxide, bubble, water instantly (be confined to large area be on fire) put out a fire.

Resinous of not saturated polyester endangers 7. 2 — health endangers the gender

1. Chemical can be passed inspiratory, feed, the way such as skin contact enters human body, the harm is healthy

2. Steam of inspiratory and much colophony of not saturated polyester can cause cough, have a headache, dazed, Mondayish, consciousness is ambiguous, disgusting wait for a symptom with vomiting.

3. Take by accident can cause guttural pang, gastralgia, headache, dazed, vomiting, coma.

4. The skin when contacting the skin directly is can weather-shack, erubescent.

5. Direct contact eye can make an eye aching, erubescent.

The emergency treatment measure when 8. the following circumstance

1. Skin contact: Rinse with many suds instantly, take off all clothings that are polluted, the hospital sends cure when the case is severe.

2. Eye contact: Rinse with many clear water instantly, turn over eyelid up, part with eyeball with ensuring remains is harmful material is rinsed clean as far as possible, must send a hospital cure next.

3. Inspiratory: Move instantly to have fresh air place, rest; Establish straight pose partly, unlock garment is buckled with benefit at breath. If breathe,difficulty should have artificial breath instantly. Toxic and serious person should send a hospital cure instantly.

4. Feed: Attention: Never urge lest because breath is undeserved,cause a harm to person,spit. Can use clear water gargle or go to a hospital treating.

The individual protective equipment when 9. is operated

1. Respiratory system: ?

2. The skin and body: ?  of  of し of  Х late dash forward  of ば of  Х late?

3. Hand ministry: Be able to bear or endure chemical safety glove. (butyl synthetic rubber)

4. Eye: ? Does crab late け knock at road to step on  fatigued idle?
