Product Description:

Description of self adhesive hdpe geomembrane sheet: 


    HDPE is a non polar thermoplastic plastic with high crystallinity and perfect electrical properties,especially the high insulation dielectric strengh.This polymer is non-hygroscopic which can be used to packing with good waterproof steam.HDPE with Middle to high molecure weight have good impact resistance at normal temperature even in the zero 40 degree Celisius.


Advantages of self adhesive hdpe geomembrane sheet:

  • high insulation dielectric strength

  • perfect impact resistance

  • good heat /cold endurance

  • no toxic

  • excellent chemical resistance

  • low water absorption

  • good temperature properties

  • great chemical stability

FAQ
1Why use HDPE sheet?                                                                                                                                 

HDPE Sheet has an almost waxy feel to it and is pretty good at being a low friction wear strip material and is used probably more than any other plastic as a wear strip on conveyors or production lines of huge companies.

 

2When can I get the HDPE price?                                                                                                               

After getting your inquiry,the reply will be send to you in 8 hours at most.If you are urgent to get the price,pls call us or tell us in the email so that we will regard your inquiry priority.

Q:How do use geomembrane to prevent sewage seepage?
Q:What is the seepage-proof geomembrane?
Co-extrusion technology is used during the production, the main material of it is high density polyethylene native resin with high quality. It has a low hydraulic permeability and excellent seepage-proof performance. The standard name of HDPE seepage-proof membrane is polyethylene geomembrane, which has a highly efficient molecular density.
Q:How to install the wall electrothermal film?
After finishing surface heat preservation measures, clean up the ground, make it smooth and flat. Aluminum foil reflective film is then laid flat, and later laying electric film. puting the electrothermal film upside, and I suggest that the safety distance between the membranes should be 20 centimeter. Then connect wires, parallel connect the electrothermal film. Do insulating treatment with both ends. after the electrothermal film installement then cover the waterproof cloth to do waterproofing process. .
Q:How to calculate the project quantity of raft foundation concrete?
The raft foundation is also known as raft plate basis. the independent foundation under column or strip foundation are all connected with connection beams, and then cast baseplates. Generally speaking, raft foundation is used when the ground bearing capacity is uneven or the foundation is weak. And raft foundation is buried relatively shallow, which can be the foundation with no need of burying deeply. It is composed of baseplates, beams and other components. Buildings have a larger loading, and the foundation bearing capacity is weak, thus concrete baseplates are often used which can bear buildings loading, and form the raft foundation with good integrity, can be an excellent resistance to differential settlement of foundation.
Q:What are the main points of paving HDPE geomembrane?
Q:What is the carbon resister
The carbon resister is made by heating polymerization, which uses an organic adhesive to make a suspension liquid by the carbon ink, graphite and the filling material and then be coated on the insulating substrate. Gaseous hydrocarbons are decomposed in high temperature and vacuum, the carbon is deposited on a ceramic rod or a ceramic tube to form a layer of crystalline carbon film.
Q:What are the applications of geomembrane in roadbed?
Waterproof
Q:Which is better for geomembrane hot melting in the middle of sliding layer of high-speed railway bridge two cloth and one membrane, lapping or docking? And what is the lapping length if it is lapping hot melting?
In general, it should not be cut according to graphic size. Shorten joint length and strain as far as possible. After geomembrane pavement, the lap width between films should be not less than 10 cm. 4. Usually set at a corner and abnormal section. 6, arrange along the gradient direction and avoid accidental damage to membrane when the temperature is low. Lap width between membranes is generally not less than 10 cm. You should measure the accurate relative size. Do not weld as far as possible during geomembrane pavement . In addition to the special requirements, Do not walk on the membrane or carry on the membrane.
Q:Which one is better, electric heating film and oil heater
This is very difficult to say, it depends on, model, quality, and price.
Q:How to use 3M light box film?
There are many kinds of light box film, colored semi transparent film, uniform light film, light blocking film, double color film, etc. Color semi transparent film is the most commonly used. There are many colors for you to choose. Customize colors according to customers' demand. Make back lighting display board by cooperating with soft lamp-box fabric. The construction method of film sticking is divided into: Dry paste method and wet paste method. It depends on different products.
