Waterproof roll material has a few kinds
From;    Author:Stand originally

The building is waterproof the norms breed with a current ability already a few kinds when by 20 centuries the bitumen asphalt felt with 50 single time develops to have different physics property intermediate and tall, new-style waterproof a material, commonly used waterproof a material composition according to material is different and general can divide for bitumen waterproof modified of a material, high polymer is waterproof a material and synthetic high polymer are waterproof a material 3 old series, still have in addition flexible polymer cement coils material, metal coils material a few kinds big.

Embryo of petroleum pitch paper is waterproof a waterproof that material is our country tradition, still take dominant place in roofing project at present. Low tender sex is poor, waterproof layer is durable fixed number of year is briefer, but the value is inferior 3 felt the roofing project of the 3 oily laid that fold a layer heats up 4 oil, 2 felt Ma hoof fat, stickup construction of fat of Leng Ma hoof
Embryo of cloth of petroleum pitch glass is waterproof a material tensile strength is high, carcass is not perishable grain, material is flexible good, wear coils than paper embryo material raises one times above to use as more the strengthens add layer and prominent position waterproof layer of paper embryo asphalt felt heats up Ma hoof fat, stickup construction of fat of Leng Ma hoof

Embryo of felt of fine of petroleum pitch Bo is waterproof roll material has be able to bear or endure goodly ability in swimming, corrosion resistance and wear, flexible also bitumen of excel paper embryo coils material often uses as fat of hoof of hot Ma of waterproof project of roofing or underground, stickup construction of fat of Leng Ma hoof

Embryo of petroleum pitch flax is waterproof a material tensile strength is high, be able to bear or endure ability in swimming is good, but carcass material easy decay often uses as roofing enhances add layer to heat up Ma hoof fat, stickup construction of fat of Leng Ma hoof

Embryo of petroleum pitch aluminum foil is waterproof roll material has very tall cut off steam permeates ability and fine of the Bo that take aperture to felt cooperates or be used alone, appropriate is used at lying between steam layer fat of hot Ma hoof is stickup

Elastomer (SBS) modified bitumen is waterproof roll material is able to bear or endure function of tall, low temperature has rise apparently, roll the roofing that the flexibility of material and fatigue resistance improve monolayer laid apparently is waterproof project or compound use cold construction or heat up frit law laid

Plasticity body (APP) modified bitumen is waterproof roll material has good strength, extensibility, hear resistance, be able to bear or endure ultraviolet illuminate and ageing resistance can monolayer laid, agree with ultraviolet radiate reachs roofing of phlogistic intense area strongly to use hot frit law or laid of cold bonding law
