Polyethylene polypropylene fiber membrane - LU

Properties:

Its surfaces are rough for non-woven fabric fibers are in an irregular and crossing structure, forming a cubic network. It can stick well with many materials, particularly with cement materials as long as no obvious water on the base layer. Due to its good overall performance, high tensile strength, anti-leakage capacity, viscidity, softness in low temperature, small coefficient of expansion and small coefficient of friction, it can be used in sand soil with stable and reliable performance. It is a green product, free from toxin and environmental pollution.

2. Functions of Products

A. Improve watertightness of building, prevent the construction from the invasion

of wind and rain, protecting the structural materials and equipments inside roof and

wall.

B. Improve the energy saving and insulation effect. Due to the unique water proof and

vapour permeable performance, when forming the protection to the insulating layer,

it can also effectively avoid the negative influence from the temperature difference

between interior and exterior. hence, it increasing the effects of insulation and energy saving

as well as providing the continuously energy saving

C. Shorten the construction period. Thanks to the good water resistant performance,

interior construction and exterior can be performed at the same time so that shorten

the construction period, reduce the construction cost.

D. Improve the residential environment. Because of the special breathable function,

the interior vapour can natural exhaust, will effectively avoid mould and condensation, keep dry, permeate and comfortable indoor, improve the residential environment.

Working process:

(1) clean-up grass-roots --- configuration adhesive --- fell into the mouth and other complex parts of the additional layer - construction waterproof layer --- waterproof layer inspection --- protective layer construction and acceptance.

(2) before the construction of the main waterproof layer must be completely cleaned up the construction site, acceptance of the leveling layer, and the sprinkler to ensure grass-roots moist. Roofing leveling layer shall comply with the GB50207-94 "roof project technical specifications, underground water-leveling layer should GBJ208-83" underground waterproof engineering construction and acceptance "provisions.

(3) with cement content of 10% ~~ 15% of PVA glue preparation of cement paste binder, stirring evenly, no precipitation, no clots, no segregation phenomenon can be used.

(4) construction of the roof of the main water layer, the focus should be on the drainage and structural complexity of detail node, the sealed and the additional layer of paste additional layer coil and the main waterproof layer of the membrane material.

(5) sealing material is a polyether-based polyurethane. If you choose other sealing material does not contain mineral oil, petrolatum, polyethylene performance chemicals products.

(6) corner shall overlay an additional layer, the yin and yang, angle, etc. are made of R = 20mm rounded.

(7) waterproofing membrane Putie should be paved method, the adhesive brushing at the grassroots level surface should be uniform, not exposed at the end, not the accumulation of adhesive after brushing, then paving the membrane, to prevent too long to affect the bonding quality.

(8) Paving waterproofing membrane shall not be wrinkled, not forced tensile membrane. Side Paving side to exclude the membrane below the air and excess adhesive, and bonded dense membrane with the primary surface and between the layers of membrane.

(9), the lap width paving the waterproofing membrane shall be not less than 100mm of upper and lower layers and the adjacent two coil joints should be staggered, one-third width.

(10) damage to the membrane defect should do additional layer additional layer of membrane defects surrounding 120mm, underground waterproof full with polyurethane glue stick, roofing cement available full bonding should be grown. The construction of the vertical structure, the membrane must be vertical to laid-down on is the exhaust from the bottom up, compacted, requiring leveling layer of membrane at the same time coating thickness of about 1mm.

Note; Paving coil in the rain, snow, fog, windy weather, and the base surface is wet. The laying of waterproofing membrane, construction temperature should be in the 5-35 ° C, the relative temperature should be less than 80%. Construction process, the procedure may not cross, all nodes in the parts must be done to strengthen the layer.

Polyethylene polypropylene fiber composite waterproof coiled materials are new waterproof materials. They are compounded by polyethylene synthetic polymers (the master waterproof layer) and auxiliary agent, aging-resistant layer, strengthening layer and PP non-woven fabric in the automatic production line.
