Product Description
PVC formulation development requires careful preparation of resin and various additives before extrusion or further processing.
Depending on the final product and processing requirements, a PVC dry blend may contain PVC resin, stabilizers, lubricants, pigments, fillers and processing aids. These ingredients need to be mixed according to a defined formulation before the material is evaluated in downstream production.
The Chenxing SHR-10A 10L PVC Laboratory High Speed Mixer is designed for small-batch PVC powder mixing and formulation development.
With a 10L total vessel capacity and approximately 7L effective working volume, the SHR-10A provides a compact mixing solution for laboratories, PVC manufacturers and material development departments.
It can be used to prepare PVC powder blends, evaluate additive combinations and conduct preliminary mixing trials before scaling up to larger equipment.
A laboratory mixer allows PVC processors to evaluate formulations without using a full-size industrial mixing unit for every trial.
Typical laboratory tasks include:
Preparing small PVC dry-blend batches.
Evaluating stabilizer and lubricant combinations.
Testing pigment and color formulations.
Comparing different filler ratios.
Studying mixing temperature and process conditions.
Preparing trial material for extrusion evaluation.
Laboratory mixing is especially useful during the development of new PVC pipe, profile, sheet and plate formulations.
The 10L vessel is designed for small-batch laboratory mixing. Its effective working volume is approximately 7L, according to the previously supplied SHR-10A specification.
The SHR-10A uses a high-speed mixing mechanism to generate intensive movement of PVC powder and suitable additives.
The previously published technical information lists a spindle speed of 2000 rpm. Final operating conditions should be confirmed against the machine configuration.
The listed standard heating method is self-friction heating, in which heat is generated through the high-speed mixing process.
Depending on the formulation and target temperature, alternative heating configurations may be discussed with the manufacturer.
The PLC control configuration supports automated operation and process management, helping operators maintain repeatable laboratory mixing procedures.
The machine uses a stainless steel pressure-cast mixing impeller that undergoes dynamic and static balance testing.
The cooling arrangement uses spiral stirring to improve material circulation, support temperature reduction and promote complete discharge.
These features are described in the existing SHR-10A technical guide and product information.
PVC Pipe Formulation
Prepare small batches of PVC powder blends for evaluating formulations intended for pipe extrusion.
PVC Profile Formulation
Support material preparation and additive blending trials for PVC profiles, including window and door profiles.
PVC Sheet and Plate Formulation
Prepare laboratory-scale blends for sheet and plate material development.
PVC Additive Evaluation
Evaluate suitable combinations of stabilizers, lubricants, pigments and fillers before production-scale mixing.
Different PVC formulations may require different mixing and discharge arrangements. The SHR-10A can be discussed with the manufacturer in the following areas:
The standard configuration uses self-friction heating. Depending on the process, a version with additional heating or a configuration without additional heating may be evaluated.
The discharge port can be discussed according to the customer's collection method and downstream equipment layout, including side or bottom discharge options.
The material of the vessel and product-contact components can be selected according to cleanliness, wear and material compatibility requirements.
The final configuration should be confirmed through technical discussion rather than assuming every option is included as standard.
Before purchasing a PVC laboratory mixer, consider:
PVC formulation: Identify the PVC resin and all additives.
Batch quantity: Confirm the required working volume.
Mixing temperature: Determine the target temperature and heating requirements.
Mixing speed: Confirm the required operating speed and control method.
Discharge design: Consider how the mixed material will be collected.
Vessel material: Confirm material-contact and cleanliness requirements.
Electrical configuration: Provide your local voltage, frequency and phase.
It is used to prepare small batches of PVC powder formulations for additive blending, color trials, material development and preliminary extrusion testing.
It is designed for suitable PVC powder mixing applications. PVC resin and compatible stabilizers, lubricants, pigments and fillers can be evaluated according to the required formulation.
The SHR-10A has a 10L total vessel capacity and approximately 7L effective working volume, based on the existing product information.
The published SHR-10A specification describes self-friction heating as the standard method. Other heating configurations may be discussed according to process requirements.
No. The SHR-10A is intended for laboratory-scale mixing and small-batch trials. Industrial PVC production normally requires larger equipment designed for higher batch volumes.
The existing technical guide identifies discharge-port customization as an option. The preferred position, size and arrangement should be confirmed when discussing the order.
