INTRODUCTION OF PZ TYPE WATER SWELLING STRIP
PZ water swelling strip, also called as PZ water
swelling water stop strip. It is a new type
waterproof material which not only owns the
performance of general rubber product but
also owns the performance of automatic
expanding when meet water. The effectiveness
of water stopping and water proofing is more
reliable than the ordinary rubber water stop
strip. Its expansion rate can reach 100-400%,
is a very good water stop material.
CHARACTERS OF PZ TYPE WATER SWELLING STRIP
PZ water swelling water stop strip produced by my company has the following characteristics:
- When rubber meets water, it will occur at least 2-5 times expansion deformation, and full of all the irregular surface, cavity and gap of the joint. At the same time, it will generating enormous contacting pressure to prevent leakage happening;
- When the joint or construction joint take place displacement, causing the gap beyond the elastic range of material, ordinary rubber water stop material will lose the water stopping effect, but this product can also through water swelling to stop water.
- Using water swelling rubber sealant as sealing material, is not only saving the amount of energy, but also can eliminate the general elastic material’s elastic fatigue caused by large compression, the waterproof effect can be more reliable, and water resistance and chemical properties resistance and aging resistant performance more excellent.
- It is mainly applied to the current seam water-proof of shield construction method, distortion seam of building, water stop of construction joints and componentof metal, precast concrete joints waterproof.
PHYSICAL PERFORMANCE OF PZ TYPE WATER SWELLING STRIP
executive standard:GB18173.3-2002
Note: water absorption expansion rate of our company can be adjusted according to the user needs.
STRUCTURE AND SIZE OF PZ TYPE WATER SWELLING STRIP
When supply the product they are made into the section of 10 x 25, 10 x 30, 10 x 40, 20 x 30, 15 x 20, ф20, ф30, R15 × R10 specifications. The length can be produced according to the requirements of users. If you need other specifications, please contact our technical department.
