1.2 ለ PVC ውህድ ድብልቅ ቁልፍ ተጨማሪዎች
The performance of PVC compounds is largely determined by the type, dosage and mixing effect of additives. Different additives play different roles in the mixing and processing process and the final products. The following are the key additives commonly used in PVC compound mixing:
1.2.1 ማረጋጊያዎች:
PVC resin is prone to thermal degradation at high temperatures (above 100℃), which will lead to discoloration (from white to yellow, brown, even black), reduction of mechanical properties and loss of use value. ስለዚህ, stabilizers must be added to PVC compounds to improve their thermal stability. Common PVC stabilizers include lead-based stabilizers, calcium-zinc composite stabilizers, barium-cadmium stabilizers, and organic tin stabilizers. ከነሱ መካከል, calcium-zinc composite stabilizers are widely used due to their environmental friendliness, non-toxicity, and good thermal stability, which are in line with the global environmental protection requirements for plastic products.
1.2.2 ፕላስቲከሮች:
Plasticizers are mainly used in flexible PVC compounds to reduce the glass transition temperature of PVC resin, improve its flexibility, toughness and processability. They can penetrate into the molecular chain of PVC, weaken the intermolecular force, make the molecular chain easy to move, thus making the PVC compound soft and easy to process. Common plasticizers include dioctyl phthalate (DOP), dioctyl terephthalate (DOTP), diisononyl phthalate (DINP), and epoxy soybean oil. ከነሱ መካከል, DOTP has the advantages of environmental protection, low volatility, and good compatibility with PVC, and is widely used in high-grade flexible PVC products (such as medical hoses, food packaging films).
1.2.3 መሙያዎች:

2.3 Key Considerations in Selecting PVC Extruders
When selecting extruders for PVC compound mixing and granulation, customers need to comprehensively consider the following factors to ensure that the selected equipment can meet their actual production needs:
2.3.1 Type of PVC Material:
Different types of PVC materials (ጥብቅ PVC, ተጣጣፊ PVC, modified PVC) have different processing characteristics, so it is necessary to select the appropriate extruder type. ለምሳሌ, rigid PVC has high viscosity and requires strong shear force for plasticization, so a conical twin-screw extruder (HTE ተከታታይ) is preferred; flexible PVC has good fluidity and low viscosity, so a single-screw extruder (ZTE MODEL) or a parallel twin-screw extruder can be selected.
2.3.2 የማምረት አቅም:
Customers need to select the extruder with appropriate production capacity according to their own production scale and market demand. If the production demand is small (less than 100kg/h), the ZTE MODEL extruder is suitable; if the production demand is large (more than 100kg/h), the HTE series extruder is more suitable.
2.3.3 Product Quality Requirements:
If the customer’s products have strict requirements on performance (እንደ ተፅዕኖ መቋቋም, ግልጽነት, የእሳት ነበልባል መዘግየት), the HTE series extruder with high plasticization efficiency and uniform mixing effect should be selected; if the product quality requirements are general, the ZTE MODEL extruder with stable performance and high cost performance can be selected.
2.3.4 Energy Consumption and Maintenance Cost:
Energy consumption and maintenance cost are important factors affecting the long-term production cost of customers. The HTE series extruder has the advantage of low energy consumption per unit product, but the initial investment is relatively high; the ZTE MODEL extruder has a lower initial investment and maintenance cost, which is suitable for customers with limited budget.
2.3.5 Compatibility with Auxiliary Equipment:
The selected extruder should be compatible with the existing auxiliary equipment (such as mixers, pelletizers, and conveyors) የተሟላ የምርት መስመር ለመመስረት, avoiding the problem of equipment mismatch affecting production efficiency.
Our professional technical team can provide one-stop consulting and selection services for customers. According to the customer’s specific needs, we will recommend the most suitable extruder model and provide customized equipment configuration and process design to help customers achieve the best production effect with the most reasonable cost.
