Automatic precast concrete hollow blocks machine
Summary:
Automatic precast concrete hollow blocks machine is designed reasonable in structure, easy for operation and maintenance, durable with high speed productivity, by which forming slabs are smooth in surface, compact in high intensity. Random cutting for any length (according to standard), flexible combination of the slab can satisfy various kinds of floor construction. This prestressed hollow core slab can simplify the construction framework. It also can reduce the bearing load of walls and beams to increase the usage area and decrease the construction cost.
When producing, firstly place the steel wire on the producing bed and tensioning according to the tensioning value. Then adjust the slab machine, feed the necessary concrete into the hopper of the slab machine, after a processing of pushing and high frequency vibrate to form the slab. When it up to standard strength after curing, the slab can be cut into needed size and stored.
Working principle:
This kind of machine is used to feed concrete into a die by means of a slide block is reciprocation along the steel tendon and compact concrete into a designed form by extrusion on a bed box in open air or a workshop ,under the operation of external vibration,surface press polish,the formed concrete is completed.
Producing flow:
Cleaning the producing bed? painting parting agent? distribute and fix ?tension the steel wire? mix and transportation the concrete material ? slab forming ?make testing block ? covering and curing ?testing the block strength ? steel wire stress relief ? cutting ? stacking in store by crane

Naphthalene Sulfonate Formaldehyde Condensate (SNF), also known as Poly Naphthalene Sulfonate (PNS) and Formaldehyde Sulfonate Condensate (FDN), is a highly effective water reducer and superplasticizer commonly used in the construction industry to improve the workability and strength of concrete.
It is a high range water reducer, high concentration naphthalene-based superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate SNF, PNS and FDN etc.
Na2SO4 has 3 grades:5% 10% 18% for exporting markets,in domestic we also have 3% 23% Na2SO4 content FDN.It contains no chloride, non-corrosive to steel bars, non-poisonous, odorless, and non-flammable.
PCE superplasticizer is the newest generation superplasticizer used for concrete in domestic and abroad.It is based on molecular designs and adsorption capacity of polycarboxylate,we do R&D and successfully produce water reducing and retention type polycarboxylate superplasticizer for concrete.With initiating systerm and reaction conditions,we achieve high adaptability.Comparing with PNS and other superplasticizer, PCE superplasticizer has many characteristic advantages in technology and performance as following:
(1) low dosage, high rate of water reducing;
(2) keep concrete good slumption retention;
(3) good compatibility with cement;
(4) small shrinkage of concrete to keep the stability of volume and durability;
(5) environmental in production and usage. Base on above advantages.
