Q

PVC Lead Salt Stabilizer Phase-Out

A

Stabilizer selection has become a compliance issue; lead salt phase-out is the trend, select the system oriented by market; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Analysis PVC;lead salt;calcium zinc;organotin;RoHS

Q

PVC Filling Modification

A

PVC filling is a balance between cost and performance; set the filling upper limit according to welding and appearance requirements; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Analysis PVC;filling;calcium carbonate;welding strength;gloss

Q

PVC Impact Modification

A

The toughness of rigid PVC relies on modifiers to make up the deficit; select the modification system according to transparency and weather resistance requirements; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Analysis PVC;impact modification;CPE;MBS;ACR

Q

PVC Lubrication System Balance

A

The PVC lubrication system is a fine balance of the formulation; internal and external differ, and excess and deficiency each have characteristic symptoms; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PVC;lubrication system;internal lubrication;external lubrication;exudation

Q

PVC Workshop Ventilation

A

HCl protection in PVC workshops is an occupational health requirement; ventilation plus testing, normalized management; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Analysis PVC;ventilation;HCl;occupational health;exhaust

Q

PVC Equipment Specialization

A

Specialization of PVC equipment is the entry threshold; missing any one of the four anti-corrosion pieces discounts equipment life; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Injection Molding PVC;dedicated equipment;anti-corrosion;bimetallic;entry

Q

PVC Recycling Challenge

A

The inherent shortcoming of PVC recycling is stabilizer consumption; limiting amount, supplementing stabilizer, and classification are the three principles of recycled use; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Material Analysis PVC;recycling;stabilizer;blending ratio;classification

Q

PVC Welding Assembly

A

PVC welding has two routes: heat and solvent; their quality points differ but neither can exceed the temperature limit; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PVC;welding;hot-air welding;solvent bonding;sealing

Q

PVC Medical Soft Tubing

A

Medical PVC is a double high standard of formulation and cleanliness; sterilization compatibility and filtration precision are key indicators; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Processing Machinery PVC;medical;soft tubing;sterilization;transparency
