Describe PVDC polymerization process and the character of main monomer. Put forward fire prevention and explosion-protection technology by process and others in PVDC polymerization production.
Along with the Safety Standard For Fire Prevention tending towards gradually strietness and rapid increasing output of plastics, the global demand and sales market of flame retardants ( FR ) ane likely to going up with the total consumption of over 1.2 million t/a in the world.
Many authoritative organizations such as API(American Petroleum Institute),ASME(American Society of Mechanical Engineers), ISO(International Standardization Organization) and NFPA(National Fire Protection Association) have presented integrated approach respectively aiming at different aspect.
In this paper, the plan of fire protection design is comprehensively dissertated from 11 sides such as the site planning, the building fire protection design, the defending of resistant to fire about steel construction, safe evacuation, water supply for fire-fighting and automatic fire extinguishing system, the arrangement of extinguisher, power supply and distribution for fire-fighting, automatic fire alarm system, electricity explosion-proof, lightning protection and antistatic countermeasure.
The results showed that the mechanical properties of the alloy was the best, and the flame retardance reached UL94 V-0 grade when the proportion of PC, ABS, compatibilizer and flame retardant was 70/30/8/15. The alloy was used in the production of flame retardant electrical switch and socket.
Although the fire behavior models used had limited testing and are based on certain assumptions, yet they are widely applied in forestry practice worldwide, as a basis for justified fire prevention and suppression planning.
Given the structural condition of the variables considered, the resulting models can be used to support the design of fire prevention policies on the long-term basis.
The paper reports lightweight plain cotten cloth was treated with Sb-Ti complex at room temperature, after which cloth was phosphory-lated, cured at 160—170℃。 Flammability of treated cotton cloth was evaluated by a number of tests, including oxygen index (01), 45° angle flammability test and durable laundering. Results indicated that OI43, during the combustion time Osec., glowing combustion time see., charred area 21. 2cm and charred length 6.0cm. The treated cotton cloth had fine flame retardancy even aft...
In this paper. aluminum tri-hydrate(ATH) pretreated with SY-1 titanate incombination with chlorohydrocarbons areused as flame retardants in LDPE foams.The above techinque has synthetic effectson enhancing flame resistance, reducing smo-king emissions and improving physical pro-perties (strength, moulding, etc.) of LDPEfoams and has been applied to the manufa-cture of foamed PE sheet filled with ATH,to achieve JISA 1322--1966 specification.
In this paper, reinforcement, antidegration and low cost fillersand flame retardant agents are studied with classification method. It ispointed out tha tinorganic fillers play an important part in composite material. Fire proofing filler of rubber and plastics products are reaserched
