Abstract
The processing technology of glue spraying type GCL is heated, raw material is Woven geofabric, bentonite and non-woven geotextile, spreads bentonite, composite acupuncture, hot melt, glue spraying, lock seaming and coiling technique through unreeling, spreading out and is made.GCL is made through composite acupuncture technique after hot melt, glue spraying, lock seaming technique by the present invention, after intermeshing web is shaped through hot-groove rolling, flat appearance, after being processed again through spray-bonding craft, the entanglement dynamics enhancing of needled web, strengthen peel strength, higher than the product of traditional handicraft.Finally again through lock seaming technique, suture product surrounding, the bentonite in middle level is not easily runed off in production, transport, laying application process, preferably ensure the anti-seepage effect of product, it is adaptable in the antileakaging engineering such as artificial lake's water scenery, refuse landfill, underground garage, roof garden, pond, oil depot and chemicals stockyard.
Description
Technical field
The present invention relates to geotechnical process field, and in particular to a kind of processing work of hot melt glue spraying type GCL
Skill.
Background technology
Waterproof blanket is one kind dedicated for artificial lake's water scenery, refuse landfill, underground garage, roof garden, pond, oil
Storehouse and chemicals stockyard etc. need to use in the environment of antiseep, and its expansion character to product, closely knit performance have higher
It is required that；Existing waterproof blanket is in use for some time because water is easily expanded to its effect and causes waterproof blanket overall
Fluff, cause the decline of water resistance；Another existing waterproof blanket mechanical property is poor, easily tears.
In recent years, the GCL using bentonite as main material production has become a kind of important waterproof, seepage control
Material.Because the essential mineral montmorillonite in bentonite has good dilatancy, water imbibition, caking property, ion exchangeable etc.
Physicochemical characteristics, the water of adsorbable tens times of own wt when it meets water, volume can increase decades of times after water suction, construct
It is limited in the confined space to form dense gel body by the pressure of top covering in journey, plays barrier water penetration
Effect, its infiltration coefficient generally can be with as little as 10-9cm/s.
At present, GCL is mainly primary raw material using natural minerals bentonites, by using needle point method by its
Be fixed on have spinning cloth and non-woven fabrics between process, but existing processing technology prepare GCL peel strength compared with
Low, the sodium bentonite in intermediate layer easily scatters loss, so that the coefficient of expansion and viscosity of waterproof blanket are substantially reduced, meets not
Antiseepage requirement.
The content of the invention
The invention provides a kind of processing technology for heating glue spraying type GCL, to solve prior art presence
Peel strength it is low influence waterproof blanket anti-seepage effect the problem of.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of processing technology for heating glue spraying type GCL, it is characterized in that raw material is Woven geofabric, bentonite
And non-woven geotextile, specific processing technology step is as follows：
（1）Unreel, be laid flat Woven geofabric and non-woven geotextile by unwinding device；
（2）Bentonite is spread at stand, and bentonite is uniformly spread out and is dispersed between Woven geofabric and non-woven geotextile, and is carried out
Compacting；
（3）Composite acupuncture, by mechanical acupuncture technology by upper strata Woven geofabric, bentonite, lower floor's non-woven geotextile
Close composite molding；
（4）Hot melt, is shaped by the hot melt of hot-rolling, makes the Woven geofabric or non-woven geotextile cloth cover phase of upper and lower layer
The fiber hot melt adhesive of mutual cross winding, strengthens entanglement dynamics, improves peel strength, and make flat appearance attractive in appearance；
（5）Glue spraying, makes upper and lower layer Woven geofabric or non-woven geotextile intersect entanglement by spray-bonding craft
Fiber is further bonded, and improves the peel strength between upper and lower layer；
（6）Lock seaming, by quiltmg piocess of lockstitching a border, makes the upper and lower layer of product link into an integrated entity, prevents the bentonite in middle level not
It is easy to run off；
（7）Batch, crimped final waterproof blanket product by coiling machine coiled.
Above-mentioned Woven geofabric is plastic flat wire braided geotextiles or long filament woven geotextile；Non-woven geotextile is terylene
Needling non-woven geotextiles or polypropylene fibre needling non-woven geotextiles.
GCL is made through composite acupuncture technique after hot melt, spray-bonding craft by the present invention, intermeshing fiber
Net hot melt, glue spraying bonding sizing, flat appearance, peel strength is higher than more than twice of traditional handicraft product, due to peel strength
Height, the sodium bentonite in intermediate layer is difficult to scatter loss, preferably ensures the anti-seepage effect of product, it is adaptable to artificial lake's water
In the antileakaging engineerings such as scape, refuse landfill, underground garage, roof garden, pond, oil depot and chemicals stockyard.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the present invention.
1 bentonite, 2 Woven geofabrics, 3 non-woven geotextiles in figure.
Embodiment
