História e tipos de película protetora por Ruby Dai

Abstract: In 1928 in St. Paul, Minnesot USA, Richard Drew invented the transparent protective film. According to its

functions, protective film is sub-divided into: high-temperature película protetora de dupla face película protetora, insulating

protective film, special protective film, pressure-sensitive película protetora, cortando película protetora,   Temporária;

superfície película protetora, funções diferentes para a indústria diferente needs.

Protective film - Process of invention

Applied in May 30, 1928 in the United Kingdom and the United States, Drew invented a very light adhesive which can

stick easily with pressure. The first trial product was not sticky enough, so Drew was told: "Get this stuff back to your

Scottish boss and ask them to put more glue! ("Scottish" means “stingy". However, during the Great Depression,

people found hundreds of uses for such protective film, from patching clothes to protecting eggs, which are of great use.)

Protective film - Action principle

Why protective film can stick on things? Of course, because it is coated with a layer of adhesive! The first adhesive was

from animals and plants. In the 19th century, rubber is the main component of adhesive, while in modern times various

kinds of polymers widespread used. The adhesive can stick to something that is due to bonding between adhesive

molecules and substrate molecules, which can bond molecules together firmly. Components of adhesive, according to

different brands, different types, there are a variety of different polymers.

Butyl protective film

1, Material composition

Butyl rubber water proof sealing adhesive tapes is mixture of butyl rubber, polyisobutene and other main raw materials,

in accordance with a special production formula, using the latest patented technology, high-quality specific polymer

materials (imported), through a special process and finally produce environmentally friendly solvent-free adhesive sealing material.

2, Product features

(1) Excellent mechanical properties: high bond strength and tensile strength, good flexibility and elongation properties,

strong adaptability to interfacial deformation and cracking.

(2) Stable chemical performance: excellent chemical resistance, weather resistance and corrosion resistance.

(3) Reliable application performance: good adhesion, waterproofing, sealing, low temperature resistance and conformability.

Good dimensional stability.

(4) Simple construction operation process

3. Scope of application

(1) Water proofing treatment for roof, underground and construction joint of new construction, and lap seal for

high-polymer water-proof material rolls.

(2) Construction joint sealing waterproofing for municipal engineering subway tunnel structure.

(3) Airtight, water proof and shock-absorbing para juntas de painéis laminados coloridos e sol bordo works.

(4) Adhesive sealing treatment for automobile assembly.

(5) Waterproof sealing treatment for joints of steel construction.

(6) Aluminum composite foil butyl protective film is suitable for waterproof sealing under the sun for civil roof, color steel,

steel structure, waterproofing membrane, PC boards and so on.

Insulating protective film

Insulating protective film is specifically used by electricians to prevent leakage of electricity and it has insulating effect.

Insulating protective film has good insulation and voltage resistance, flaming retardancy, weather resistance and other

features. It is suitable for connecting wires, electrical insulation protection and so on.

Production process: PVC film as the substrate coated with rubber pressure-sensitive adhesive.

Anti-corrosion protective film

It is adhesive tape used for antiseptic wound, which is divided into cold wrap and heat wrap. Cold wrap tapes generally

include polyethylene (composite) type anti-corrosion película protetora, polipropileno reforçado de fibra anti-corrosion

protective film, aluminum foil UV resistant anti-corrosion película de protecção, de polietileno 660 (asfalto modificado)

protetor filme, dupla face adesiva anti-corrosão dentro de fita (Esta película protetora é raramente usada na China,

mas muito prático muito amplamente utilizada nos países em foreigin. Geralmente, para export) and epoxy coal asphalt

anti-corrosion protective film. Executive standards are SY / T0414-98 and SY / T0447-96. Heat wrap tapes,

also known as radiation cross-linking . calor de polietileno fita envoltório do psiquiatra O adesivo deve ser fundido com calor

durante a aplicação Às vezes.   necessidades; a ser   assistida; por livre de solvente epóxi coating and becomes three-layer

structure anti-corrosion. Executive standard is SY / T0413-2002.

Shielding protective film

It is a kind of metal foil or conductive fabric with high conductive adhesive. Its conductive adhesive and conductive substrate

composes a complete conductor, which can bond with any metal face to achieve electrical connection and electrical overlap

of gaps. Shielding conductive protective film is economical and practical shielding materials, which is easy to use.

Iron composite protective film

Operating temperature range: - 40 ℃ -100 ℃.

Purpose: seams between buildings, bridges, subways and underground concrete.

Features: waterproof, high bonding strength, high tensile strength, good adaptability to interface deformation and cracking.

Excellent chemical resistance, weather resistance and corrosion resistance. 80 ℃ high temperature does not flow while low

temperature 40 ℃ does not crack.

Polyimide protective film

Polyimide protective film, also known as Kapton protective film, polyimide film as the substrate coated with imported organic

silicon pressure sensitive adhesive. It has properties such as high temperature resistance, acid resistance, solvent resistance,

electrical insulation (H level), radiation proof and so on.

Temporary superfície protectora film

Usage: Provide a protective barrier to scratch, mark, damage and dirt at the process of

transportation and installation.

Applications: Stainless steel plate, Stainless steel deep drawing, aluminum profile, aluminum window & door, coated aluminum

plate, colored steel plate, mirrored steel plate, glass, carpet, acrylic (PMMA) sheet, PVC sheet, ABS sheet, aluminum plastic

composite panel, decorative laminate, artificial marble, ceramic, aluminum ceiling and so on.

Advantages:

Good weatherability, stalbe adhesive strength, can be easily applied and removed. Leaving no residue glue after removal.

UV resistance for up to 12 months.
