Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the embodiment of the utility model provides a pair of no glue imbibition core body, no glue imbibition core body top-down includes non-woven fabrics top layer 1, drainage layer 2, polymer imbibition layer 3 and non-woven fabrics bottom 4, hot pressing composite connection between non-woven fabrics top layer 1, drainage layer 2, polymer imbibition layer 3 and the non-woven fabrics bottom 4, drainage layer 2 and polymer imbibition layer 3 correspond and are provided with drainage hole 5, be provided with the fixed cotton 6 of drainage in drainage hole 5, drainage hole 5 and the fixed cotton 6 slope setting in drainage layer 2 and polymer imbibition layer 3 of drainage.
Through with hot pressing complex connection between non-woven fabrics top layer, drainage layer, polymer imbibition layer and the non-woven fabrics bottom, avoided the use of colloid, reduced the harm of colloid, guaranteed security and feature of environmental protection, drainage hole and drainage fixed cotton are leading the liquid layer and the setting of polymer imbibition in-situ slope, can further guarantee drainage layer and polymer imbibition layer connection fixity and continuity.
In use, liquid gets into the polymer imbibition layer through the drainage layer, drainage layer and polymer imbibition layer imbibition back inflation, make the fixed cotton of drainage and drainage layer and polymer imbibition layer fastening connection, drainage layer and polymer imbibition layer are when producing relative transverse force, the fixed cotton of drainage can be dragged drainage layer and polymer imbibition layer, thereby improve the degree of connection of drainage layer and polymer imbibition layer, the fixed cotton of drainage can further absorb liquid and leading-in polymer imbibition layer when a large amount of liquid appears, thereby further promote the conductivity.
Preferably, the liquid guide holes 5 and the liquid guide fixing cotton 6 are obliquely arranged in a crossing manner in the liquid guide layer 2 and the polymer liquid absorbent layer 3. The liquid guiding and fixing cotton 6 is a liquid guiding and fixing cotton stick. The inclined included angle between the liquid guide fixing cotton 6 and the polymer liquid absorbing layer 3 is 15 degrees.
