Description
Technical field
A kind of PVC paste resin test device is the utility model is related to, particularly a kind of PVC paste resin gel
Test device.
Background technology
Polyvinyl chloride（PVC）Paste resin as the term suggests be such a resin mainly so that paste forms are made to apply, Ren Menchang
It is referred to as plasticized paste with such a paste（PVC paste）, be the igelite under rough a kind of unique liquid form.Paste tree
Fat is often made by emulsion and microsuspending method.
For PVC paste in heating process, molecular thermalmotion aggravation, plasticizer diffuses more readily into swelling tree inside resin particle
Fat, reduce free plasticizer relative amount, so as to which PVC paste loses flowability, plasticized paste is in mechanical strength close to " zero "
Dry state, this process is referred to as gelation.
PVC gel process is significant in the production of PVC paste product process, such as is dipping in modeling glove production
In, glove mould after heating is immersed to prefabricated PVC plasticized pastes, the PVC paste close to mould forms gel layer, and unnecessary thickener exists
Break away from moulds under Action of Gravity Field, gel layer, which plastifies and cooled through high temperature, can be made into paste resin gloves.Rubbing method flooring laminate,
In the production processes such as support methods artificial leather, slush moulding footwear, also to pass through gelation process.Therefore PVC paste gelatinization performance is to pasting
Product technique and product quality have important influence.
Gelation method of testing mainly has：
1st, Brabender plasticizing instrument method
PVC paste torque variation with temperature is determined under the conditions of constant heatingrate and draws temperature-torque of gelation process
Curve.As temperature rises, it is the sample gelling temperature that the temperature that torque rises, which occurs, for PVC paste sample.
2nd, rotation viscometer method
Under a steady temperature, changed with time using viscosity in different rotor measure different range and draw gel
The when m- viscograph of change process.For ease of the gelatinization performance of more different systems paste, paste viscosity is reached a certain value when institute
Take time and be defined as gelation time, and to the quantitatively characterizing as PVC paste gelatinization performance.
Brabender curve, because programming rate is slower in experiment, the gelation process in test is not equivalent to actual
Gelation process in production, but Brabender plasticizing instrument can determine overall process of the PVC paste from gelation to fusion plastification, energy
Enough gelation features for more fully reflecting PVC paste；The range of viscosities of rotary viscosity design determining is narrower, can only determine relatively low gel
The indicatrix of change degree, and gelation overall process can not be reflected.
The content of the invention
Goal of the invention of the present utility model is to provide a kind of test accurate, simple in construction PVC paste resin gel
Test device.

A kind of PVC paste resin gel test device, including heater block, control unit and test groove structure, control
Part processed is connected with heater block circuit, and the heating source in heater block uses electronics universal furnace, is equipped with above electronics universal furnace
Heated Copper harden structure, heat and be provided with test groove on copper coin.
The utility model of above-mentioned technical proposal is compared with prior art, simple in construction, easy to operation, and test result is accurate
Rate is high.
Preferred scheme of the present utility model is：
Control unit includes UP8T timers and ZNHW type electric energy-saving temperature controllers, and timer and temperature controller are put
In in same casing.
Heated Copper harden structure is identical with DL-1 type electronics universal furnace heating surface (area) (HSs, 10~20mm of thickness, test groove diameter ∮
