Product survey
Production technology of SK EVA waterproof board uses domestic
advanced two-section pressing and single screw extrusion method.
Intensifier and antioxidant are added into raw material resin EVA;
the board is formed after heating, melting, plastification and
pressing and traction, earthwork fabric (signal layer) with hanging
belt is composed into integral by heating to form composite
waterproof board. Pressing and rolling method can be also used,
i.e., melting and plastification are made by resin pressing
machine, melting shape blank pressed out from narrow mold mouth of
the machine is melted into integral with hanging belt, and flat
film is formed by rolling of roller and cooling, or the blank is
melted into earthwork fabric with hanging belt, and composite
waterproof board is formed by rolling of roller and cooling.
SK polyvinyl chloride (PVC) waterproof board is waterproof sheet
with high quality and macromolecule. It is macromolecule waterproof
rolling material that is produced from PVC resin by adding
additives such as plasticizer, ultraviolet resistor, aging resistor
and stabilizer and by pressing method.
SK ECB waterproof board is the preferred sheet of foreign and
domestic tunnel, dike and bank waterproof projects. Its molecular
weight reaches **0,**0. Its performances are changed with ratio of
vinyl acetate content, and can meet the
requirements of various applications respectively. It has good
flexibility, cold resistance, stress breakage resistance and small
specific gravity, and is especially suitable for waterproof
material of vault inside surface. It is the sheet produced
from ethane and vinyl acetate
copolymer by two-section pressing and three-roller rolling. The
material is translucent, and belongs to environmental protection
material.
