Is linoleum felt toxic?

Is linoleum felt toxic? It is a commonly used tool in the felt industry. It is usually made of wool. The raw material used is polyester fiber. Linoleum is divided into paper-based linoleum and glass cloth. There are three types: tire felt and asphalt oil paper. Oil felt is widely used in life. Is oil felt toxic? Is linoleum toxic? 1

It is toxic and has a strong carcinogenic ability, so it is generally used for outdoor decoration and leak repair, not for indoor decoration. As for the smell from roof asphalt...it's better to smell it less, it's really not good for your health. Such substances usually emit a variety of volatile organic compounds, which are harmful to the respiratory tract if inhaled for a long time. At high concentrations, they may also have an impact on the nervous system and hematopoietic system.

Main uses of oil felt: Mechanical oil sealing uses wool felt rolls with good oil sealing performance. Ovens and freezers need to be sealed with flat felts with strong sealing performance.

Asphalt paper is also called tar paper. A general term for various processed papers obtained by saturated impregnating, coating or laminating base paper with asphalt or other asphalt-containing substances.

How to make linoleum paper: Generally, rags, waste paper, etc. are used as raw materials. Some animal hair and slag cotton can be mixed with it, and it can be directly beaten and copied. During processing, the base paper is passed through molten asphalt and extruded by hot rollers so that the asphalt saturates the paper layer and squeezes out excess asphalt. The surface is then sprinkled with talcum powder or fragmented mica, and then cooled. Less used now.

How to splice linoleum paper: The linoleum paper we buy comes in a roll, but when we pave it, we will inevitably have to splice two linoleum papers. If the key steps of paper paving are not done well, leakage will easily occur. Let me introduce it to you in detail below.

The linoleum should be flattened and compacted, and the overlapping edges should be carefully sealed with asphalt cementing materials. The thickness of the asphalt cementing material bonding each layer of linoleum is generally 1-1.5mm, and the thickness should not exceed 2mm. When paving, the linoleum should be rolled while applying glue. The bonding is required to be firm and the paving should be straight. Is linoleum felt toxic? 2

Linoleum is a building material made from animal hair or plant fiber felt or thick paper soaked in asphalt. It is impermeable and tough and can be used for roofs, foundations, and basement walls. Waterproof and moisture-proof layers. Also called linoleum.

Overview

Linoleum, commonly known as oil felt, is a general term for asphalt waterproofing membranes. It generally refers to a base made of base paper or fabric, fiber felt, and metal foil, which is dip-coated with asphalt or modified. A waterproof membrane made of asphalt, modified tar, and sprinkled with cloth. According to the type of asphalt and spreading cloth, tire base material, functional characteristics, etc., it can be divided into: petroleum asphalt linoleum, coal asphalt linoleum, low temperature resistant linoleum, powder surface linoleum, sand surface linoleum, colored sand surface linoleum, mineral wool paper linoleum, asphalt Glass cloth linoleum, metal foil linoleum, hot melt linoleum, self-adhesive linoleum, oil-retardant linoleum, etc. If more rubber or plastic modified materials are added to the asphalt, the tire base can also be removed to make tireless linoleum.

my country's linoleum industry developed in the early days of liberation. At that time, my country's mineral oil reserves had not yet been exploited in large quantities, so coal tar asphalt was mostly used as raw material to produce linoleum. Coal tar asphalt products are of low quality and can only be used in general construction projects and do not meet the quality requirements of important projects. In recent years, my country's petroleum resources have been heavily exploited, and the linoleum industry in various places has mostly used petroleum asphalt to produce linoleum. Basically it can meet domestic needs.

Types and specifications

Linoleum is divided into three types: paper-based linoleum, glass cloth-based linoleum and asphalt linoleum paper.

Paper felt is made by impregnating base paper with petroleum asphalt with a low softening point, then coating both sides of the paper with petroleum asphalt with a high softening point, and then spreading isolation materials such as stone powder, mica flakes, etc. A perfect waterproofing membrane.

Glass cloth linoleum is a kind of waterproof membrane made by using Shishan asphalt as the coating material, dipping both sides of the glass fiber cloth, and then spreading the isolation material.

Asphalt oil paper is an uncoated paper waterproofing membrane made of base paper impregnated with petroleum asphalt with a low softening point. Oil paper can be used to prevent moisture, or as the lower layer of multiple waterproof layers.

If the surface isolation material is stone powder, it is called powder felt, and if it is mica flakes, it is called sheet felt.

Petroleum asphalt linoleum is divided into three specifications: No. 200, No. 350, and No. 500. Asphalt oil paper is divided into two specifications: No. 200 and No. 350.

The width of linoleum and oil paper is divided into two types: 915mm and 1000mm.

No. 200 linoleum is mostly used for simple waterproofing construction, moisture-proofing and packaging. No. 350 and No. 500 pink felt are suitable for each layer and surface layer of multi-layer waterproofing; sheet felt is suitable for single-layer waterproofing. Petroleum asphalt oil paper is suitable for building moisture-proofing and packaging, and can also be used as the lower layer of multi-layer waterproof layers. Is oil felt toxic? 3

The raw material used in felt is polyester fiber. Polyester fiber itself is flammable, so it needs to be blended with flame-retardant fiber during production, so that the finished product will be resistant. Inflammable. It is necessary for most products to use materials with flame retardant properties. Therefore, when selecting felt products, flame retardant performance screening is also required.

Felt itself is a very good fire-retardant material, with excellent flame-retardant and fire-retardant properties. It has been tested to be a B1 fire-retardant grade, and its fire-retardant performance is much higher than that of traditional felt materials.

1. Felt, a commonly used tool in industry, is mostly made of wool, but also made of cow hair or fiber, which is processed and bonded. The main characteristics are that it is elastic and can be used as a material for shockproof, sealing, lining and elastic wire card cloth base felt. Used in mechanical anti-vibration, oil-containing lubrication, friction resistance and other industries.

2. Wool felt is made of natural wool, which is machined and bonded using the milling characteristics of wool (not interlaced with warp and weft). Wool itself is also a biodegradable, non-toxic and ecologically friendly material. Elastic, wool felt can be used as shockproof, sealing, padding and elastic wire card cloth base felt material. It has good bonding performance and is not easy to loosen. Wool felt can be die-cut into parts of various shapes.

What is felt

Felt is used in various industrial machinery - anti-vibration, oil-containing lubrication, friction resistance and other industries.

Felt can be die-cut into parts of various shapes, or used as heat insulation and polishing materials. It can also be made into felt insoles, car door and window seals, central door and window seals, etc.

Felt products cannot be bleached. When cleaning, use gentle pressure with your hands. Just scrub the dirty parts lightly. Do not scrub with a brush.
