Polyvinyl chloride (PVC for short) as the world's largest amount of general plastic, according to different uses can add different additives, according to the amount of plasticizer different PVC products can be divided into PVC hard products and PVC soft products. Different PVC lubricants lead to different physical and mechanical properties of PVC plastics. PVC products with the same purpose due to material formula, quality of auxiliary materials, production equipment, production process and other reasons lead to a large difference in product quality.
Go traidisiúnta, roinnimid bealadh táirgí crua PVC isteach i lubrication inmheánach agus seachtrach, ach le riachtanais cháilíochta athraitheacha na dtáirgí, chomh maith leis an athrú ar éileamh an mhargaidh, níorbh fhéidir leis an teoiric lubrication bunaidh freastal ar riachtanais theicniúla táirgeadh sonrach.
Is é meicníocht clasaiceach lubrication inmheánach agus seachtrach ná go n-úsáidtear lubrication inmheánach mar mhodh éifeachtach chun slaodacht PVC a laghdú, rud a fhágann go laghdaítear giniúint teasa frithchuimilte agus feabhas a chur ar sreabhacheacht na n-ábhar. Go háirithe chun neart leá roinnt táirgí a chinntiú, an brú ar ais a mhéadú; Tá an bealadh seachtrach, mar "ciseal bealaithe", idir ábhair agus trealamh chun gile na dtáirgí a chinntiú agus an t-am plaisteachithe a choigeartú.
