Polyethylene waxyog cov hmoov dawb uas muaj qhov muag muag ntawm li 100-117 ℃.Vim nws qhov hnyav hnyav molecular, siab melting point thiab tsis tshua muaj volatility, nws kuj qhia pom tseeb lubrication nyhuv ntawm qhov kub thiab txias.Nws yog tsim rau tawv PVC ib leeg thiab ntxaib-ntsia hlau extrusion, nrog ib tug ntau npaum li cas ntawm 0.1-0.5phr.

Thaum lub sij hawm tsim cov PVC yeeb nkab profiles, yuav muaj qhov tshwm sim ntawm qhov tsis zoo thiab tsis pom kev ci ntsa iab.Paraffin, raws li PVC lubricant, muaj qhov muag tsis tshua muaj thiab tsis zoo dispersion.Vim tias qhov kub thiab txias hauv cov txheej txheem tsim khoom, cov tshuaj paraffin yog liquefied thiab evaporated rau hauv lub xeev gaseous.Nws yog qhov nyuaj rau paraffin los ua lub luag haujlwm hauv kev siv cov kav dej PVC.Cov nyhuv dispersion tsis zoo, thiab PVC yeeb nkab profiles yuav stained los ntawm qhov chaw.
PVC yeeb nkab profiles uas tsim los ntawm polyethylene wax (PE wax) yuav tsis muaj teeb meem li no, vim hais tias lub softening point ntawm polyethylene wax ntoo lub cev yog siab, thiab nyob rau hauv lub kub kub, polyethylene wax (PE wax) tsuas yog ua kua, muaj viscosity siab thiab. tsis zoo dispersion ntawm polyethylene wax (PE wax), tab sis qhov ci ntsa iab zoo heev.Yog tias cov viscosity ntawm polyethylene wax (PE wax) tsawg, qhov dispersion zoo heev thiab qhov ci ntsa iab yog OK.
Qingdao Sainuopolyethylene waxmuaj concentrated carbon tis, concentrated molecular hnyav tis, tsis tshua muaj thermal poob thiab zoo thaum ntxov, nruab nrab thiab lig lubrication kev ua tau zoo.Tsawg viscosity, siab softening point, loj molecular hnyav, zoo thermal stability, zoo heev sab nrauv lubrication thiab muaj zog hauv lubrication.Yooj yim rau disperse, uas tuaj yeem txhim kho qhov ci ntawm cov khoom;Zoo compatibility, sib xws nrog ntau yam khoom thiab los tiv thaiv nag lossis daus;Zoo demoulding kev ua tau zoo, lub sij hawm ntev nruam ntau lawm thiab lwm yam zoo, nrog rau cov yam ntxwv zoo heev.Peb yuav xaiv qhov tsim nyog polyethylene wax raws li qhov sib txawv ntawm cov neeg siv khoom.

Polyethylene wax muaj qhov chaw muaj zog heev thiab muaj cov saw hlau ntev uas tsis yog-polar carbon.Nyob rau hauv cov qauv ntawm polyethylene wax, ib feem sib xws nrog yas nyob rau hauv polarity plays lub luag hauj lwm ntawm internal lubrication, thiab ib feem incompatible nrog yas nyob rau hauv polarity plays lub luag hauj lwm ntawm sab nraud lubrication thiab demoulding.
Daim ntawv thov tseem ceeb ntawm polyethylene wax yog nyob rau hauv kev ua ntawm PVC.Piv nrog fatty acid lubricants, polyethylene wax tsis muaj kev cuam tshuam rau yaj nro thiab Vicat softening point, thiab muab nws zoo heev los tiv thaiv adhesion thiab ntws tswj.Hauv txoj kev ua haujlwm tshwj xeeb, PE ciab tuaj yeem siv los tswj cov melting.Txawm hais tias tus nqi loj, nws tuaj yeem muaj kev sib raug zoo nrog lwm cov khoom.
Polyethylene wax yog tib lub npe yas lubricant uas muaj peev xwm ua tau ob qho tib si sab hauv thiab sab nrauv lubrication (demoulding nyhuv), tswj siab transparency thiab tsis tshua muaj txiaj ntsig ntawm gelation.Tsis tas li ntawd, qhov tsawg volatility ntawm PE ciab yog ib qho tseem ceeb heev rau calendering thiab nqus degassing,.
Raws li cov roj nplua nyeem sab hauv, polyethylene wax muaj kev sib raug zoo nrog cov polymers.Nws ua lub luag haujlwm hauv kev txo cov cohesion ntawm polymer molecules nyob rau hauv lub polymer, thiaj li los txhim kho lub internal kev sib txhuam thaum tshav kub kub tiam thiab yaj fluidity ntawm yas yaj.
Kev ua haujlwm ntawm PE ciab li cov roj nplua nyeem sab nraud yog txhawm rau txhim kho kev sib txhuam ntawm cov polymer yaj thiab kub hlau ntawm cov khoom siv.Nws muaj qhov tsis zoo sib xws nrog polymer thiab yooj yim txav los ntawm cov yaj mus rau sab nraud, yog li nws tuaj yeem tsim cov txheej nyias nyias ntawm qhov sib txuas ntawm cov yas yaj thiab hlau.
Qingdao Sainuo Chemical Co., Ltd.Peb yog cov chaw tsim khoom rau PE ciab, PP ciab, OPE ciab, EVA ciab, PEMA, EBS, Zinc / Calcium Stearate ....Peb cov khoom tau dhau REACH, ROHS, PAHS, FDA kuaj.
Sainuo so assured ciab, txais tos koj nug!
