Dab tsi yog Cov Haujlwm Ntawm PE Wax hauv PVC

PE wax muaj qhov chaw muaj zog heev ntawm cov hlau tsis muaj polar carbon ntev heev. Nyob rau hauv nws cov qauv, lub ncov qaumteb qabteb ib feem sib xws nrog yas plays lub internal lubrication lub luag hauj lwm, thiab lub ncov qaum teb ib feem incompatible nrog yas plays lub luag hauj lwm ntawm sab nraud lubrication thiab pwm tso.

Daim ntawv thov tseem ceeb ntawm PE ciab hauv PVC ua. Piv nrog rau fatty acid lubricants, nws tsis cuam tshuam rau lub melt nro thiab vika softening point, thiab muab zoo heev adhesion tsis kam thiab tswj ndlwg los.In cov txheej txheem tshwj xeeb, PE ciab yuav siv tau los tswj lub melting. Txawm tias tus nqi loj, nws tuaj yeem sib xyaw nrog lwm cov khoom xyaw.

PE wax yog tib lub npe yas lubricant uas muaj ob qho tib si sab hauv thiab sab nraud lubrication (tso tawm) thaum tuav lub siab pob tshab thiab tsis tshua muaj txiaj ntsig ntawm gelation. Tsis tas li ntawd, cov yam ntxwv tsis tshua muaj hluav taws xob tsawg ntawm PE wax yog qhov tseem ceeb heev rau calendering thiab nqus degassing.

Raws li cov roj nplua nyeem sab hauv, PE wax muaj kev sib raug zoo nrog cov polymer, uas txo cov kev sib txuam sib xyaw ua ke, yog li txhim kho cov kev sib txhuam sab hauv ntawm cov yas yaj thiab fluidity ntawm cov yaj.

Kev ua haujlwm ntawm PE ciab raws li cov roj nplua nyeem sab nraud yog txhawm rau txhim kho kev sib txhuam ntawm cov polymer yaj thiab cov hlau kub ntawm cov khoom siv ua haujlwm. Nws muaj qhov tsis zoo sib xws nrog polymer thiab yooj yim txav los ntawm cov yaj, yog li nws tuaj yeem tsim ib txheej nyias ntawm lubrication ntawm qhov sib txuas ntawm cov yas yaj thiab hlau.
