General Requirements for Plastic Materials for All-Plastic Explosion proof Fluorescent Lights

Brief introduction of all-plastic Explosion proof Fluorescent Lights

All-plastic explosion-proof fluorescent lamp is with the rapid development of petroleum, chemical and other industries, lighting lamps and lanterns in the production, storage, rescue in the use of more and more widely, more and more varieties. How to prevent the occurrence of accidental explosion of lighting fixtures in explosive gas hazardous places has become a very important issue.

As lighting fixtures in the work of the inevitable sparks or the formation of hot surfaces, once they meet with the production or rescue site of explosive gas mixtures, will lead to the occurrence of explosive accidents. Therefore, as the most widely used lighting fixtures, its explosion-proof technology has long attracted widespread attention and great importance.

Plastic Explosion proof Fluorescent Lights by the lamp holder, lamp holder explosion-proof shell, light source and light source protective cover. Light source by rare earth tricolor fluorescent tubes and high power factor electronic ballasts, electronic ballasts have the outer edge of the explosion-proof sheath, explosion-proof sheath and lamp socket explosion-proof shell are used to contain glass fibers more than 20% of the polyethylene terephthalate (PBT) made of the light source shield is only a layer of molecular weight of 25,000 or more of the high-density polycarbonate (PC) made of. The utility model simple structure, low power consumption, light weight, low cost, explosion-proof performance is excellent.

All-plastic explosion-proof fluorescent lamp plastic material technical requirements

The technical requirements of plastic materials should include the following:

a) the name or registered trademark of the resin manufacturer or synthesizer;

b) Material identification, including model number and color;

c) Possible surface treatment, such as varnish application;

d) The temperature index TI corresponding to the 20,000 h point of the thermal stability curve, at which point the material shall be tested in accordance with GB/T 11026.1-2016, “Heat Resistance of Electrical Insulating Materials Part 1: Aging Procedures and Evaluation of Test Results”, GB/T 11026.2-2012, “Heat Resistance of Electrical Insulating Materials Part 2: Selection of Test Judgment Criteria” and GB/T 9341-2008 ‘Determination of Bending Properties of Plastics’ the bending strength is reduced by no more than 50% when measured.

If the material does not break in the test before heat exposure, the temperature index shall be determined in accordance with the tensile strength determined by the test bars of category 1A or IB as specified in GB/T 1040.2-2022 “Determination of Tensile Properties of Plastics Part 2: Test Conditions for Molded and Extruded Plastics”. The relative thermal index (RTI-mechanical strength or RTI-mechanical impact) may be substituted for the TI in accordance with the value determined by ANSI/UL 746B-2024, Safety Standard for Polymeric Materials Long-Term Performance Evaluation;

e) Where applicable, data support for compliance with UV resistance. In the certification process can provide material samples for UV resistance test, or provide technical data in line with the requirements of GB/T 3836.1-2021 “Explosive Environment Part 1: General Requirements for Equipment” Clause 7.3.

Reference standard:

GB/T 3836.1-2021 Explosive atmospheres Part 1: General requirements for equipment [S].

Full-plastic explosion-proof fluorescent lamps FAQ:

1. Is the light source an ordinary fluorescent tube?

A: Usually special explosion-proof fluorescent tubes and LED tubes T8. 2.

2. all-plastic shell is not high temperature?

A: High-quality engineering plastics (such as flame retardant PC) can withstand -40 ℃ ~ +120 ℃ environment, and the surface temperature is limited by the explosion-proof level (such as T6 ≤ 85 ℃), no risk of deformation under normal use.

3 What are the disadvantages compared with metal explosion-proof lamps?

Mechanical strength is slightly lower: violent impact may be damaged (select the impact resistance level IK08 or more products).

Higher cost: the price of high-end plastic material is higher than ordinary steel plate.

4. Can it be used in outdoor environment?

A: Yes! However, it must also meet the following requirements: explosion-proof certification + IP65 or higher protection level (against water spray and dust). The material has UV treatment to prevent the plastic from aging and becoming brittle.

5. Is there an emergency device?

A: Emergency device can be added, emergency time 90min-180min.
