Questions regarding the insulation material in chemical plants
Thread Content
What type of insulation material is used in the factories where you, fellow seafarers, work? We use asbestos, and whether it’s being removed or installed, dust particles fly everywhere; they cause pain and itching when they come into contact with the skin. I’ve been in other workplaces where composite silicate insulation boards were used; they are soft, and there was no issue of fibers flying around, so it’s clearly harmless to the human body. But for some reason, many factories still use asbestos, which is harmful to human health, for insulation, and there seem to be no regulations prohibiting its use.
This is a composite silicate board; it just doesn’t look bothersome at all.
Composite silicate boards are not very convenient to work with
In areas with low temperatures in our facility, rock wool is used, while silicate boards are used for steam pipelines or pipelines carrying hot materials; however, all containers use the latter. Although this substance is banned internationally, whether to use it or not depends on the national conditions, or on whether the organization has the funds to do so
When maintaining heat exchangers or containers, these things are the most annoying.
The insulation materials used for the equipment we produce are generally rock wool or aluminum silicate for heat retention, and polyurethane foam for heat insulation
It’s still the price issue. Fiber glass insulation is used on the inside, and iron sheeting is used for the outside. However, the low-temperature area is insulated with polyurethane foam.
Insulation for low-temperature pipelines generally consists of rubber-plastic foam along with a foaming agent
It should be rock wool, not asbestos; asbestos is not allowed to be used. Rock wool is half as cheap as aluminum silicate products, which is why it is still widely used
Asbestos is strictly prohibited from use in Europe, as it is said to have a severe impact on health; foreigners present at the site would immediately leave upon seeing asbestos! Strike! There are no such requirements in the country at present; it is also hoped that relevant laws and regulations will be introduced as soon as possible to effectively protect the interests of employees.
