Nyob rau hauv tus txheej txheem ntawm polyethylene ntau lawm, me me ntawm oligomer yuav raug tsim, uas yog, tsis tshua muaj txheeb ze molecular hnyav polyethylene, kuj hu ua polymer wax, los yogpolyethylene waxluv luv.Polymer wax yog cov khoom tsis muaj tshuaj lom, tsis qab, tsis muaj corrosive, dawb los yog daj me ntsis nrog cov txheeb ze molecular hnyav ntawm 1800 ~ 8000. Nws tuaj yeem ua rau hauv cov blocks, flakes thiab hmoov raws li xav tau.Hauv kev tsim khoom ib txwm muaj, qhov no ntawm cov quav ciab tuaj yeem raug ntxiv ncaj qha rau polyolefin raws li cov khoom siv ntxiv, thiab muaj kev ua haujlwm txias txias, tiv taus cua sov, tshuaj tiv thaiv thiab hnav tsis kam.
Nyob rau hauv cov txheej txheem ntau lawm ntawm polyethylene wax, tswj qhov kub thiab txias thiab lub sij hawm yog ib qho tseem ceeb los xyuas kom meej cov khoom thiab zoo ntawm cracking ciab.Kev kub kub tawg yuav tsum muaj ntau tshaj 300 ℃.Yog tias qhov ntsuas kub qis dhau, qhov degradation tsis tiav, cov saw hlau molecular tsis tuaj yeem tawg tag nrho, thiab cov khoom fluidity tsis zoo, uas tsis zoo rau ntau yam kev siv;Qhov kub thiab txias yog siab dhau, lub zog siv ntau dhau, tus nqi tsim khoom nce, qhov fluidity yog ceev heev, lub sijhawm txias yog ntev dhau lawm, thiab qhov paug tawm sai heev, uas yooj yim ua rau combustion thiab kev sib tsoo.Tsis tas li ntawd, qhov tso tawm circulating cua txias system yuav tsum zoo meej.Yog tias qhov txias txias ntawm chav tsev tsis zoo, cov ntaub qhwv polyethylene raug rau qhov kub thiab txias hauv huab cua, uas yooj yim rau oxidized, thiab cov khoom yog grey.Qhov ntsuas kub tawm yuav tsum tswj qis dua 800 ℃.

Kev siv ntawm polyethylene wax
1. Daim ntawv thov ntawmpe wax raws li dispersant
Polyethylene wax yog ib hom roj nplua nyeem thiab tso tawm tus neeg sawv cev nrog zoo sab nraud lubrication.Ntxiv rau cov roj hmab thiab cov yas tuaj yeem txhim kho kev ua tau zoo, txhim kho qhov gloss thiab hnav tsis kam ntawm cov khoom, pab txhawb kev tawg ntawm fillers thiab pigments, thiab tseem tuaj yeem siv los ua cov khoom siv raw ntawm cov xim yas masterbatch.
Daim ntawv thov ntawm polyethylene wax hauv Xim Masterbatch
Polyethylene wax yog dav siv nyob rau hauv cov xim masterbatch ua.Lub hom phiaj ntawm kev ntxiv polyethylene wax tsis yog tsuas yog los txhim kho cov txheej txheem ntawm cov xim masterbatch, tab sis kuj txhawb cov xim dispersion hauv cov xim masterbatch.Pigment dispersion tseem ceeb heev rau xim masterbatch.Qhov zoo ntawm Xim Masterbatch feem ntau yog nyob ntawm cov xim dispersion.Pigment dispersing thiab lustrous masterbatch muaj cov xim muaj zog, cov xim zoo nkauj thiab cov xim tsis muaj nqi.Polyethylene wax tuaj yeem txhim kho qhov tawg ntawm cov xim rau qee yam.Nws yog ib hom dispersant nyob rau hauv zus tau tej cov xim masterbatch.

2. Daim ntawv thov ntawm polyethylene wax li lubricant
Polyethylene wax yog ib hom roj nplua nyeem thiab tso tawm tus neeg sawv cev nrog zoo sab nraud lubrication.Ntxiv rau cov roj hmab thiab cov yas tuaj yeem txhim kho kev ua haujlwm zoo thiab gloss nto thiab hnav tsis kam ntawm cov khoom.
Action mechanism: Lub luag hauj lwm ntawm lubricant yog los txo qhov kev sib txhuam ntawm qhov chaw ntawm kev sib cuag ntawm cov khoom siv polymer thiab cov tshuab ua haujlwm thiab nruab nrab ntawm cov saw hlau molecular.Lub qub yog hu ua lwm lubricant thiab tom kawg yog hu ua internal lubricant.Internal lubricant thiab polymer muaj qee yam kev sib raug zoo.Nyob rau hauv chav tsev kub, lub compatibility yog me me, thaum nyob rau hauv high kub, lub compatibility nce raws li.Tus nqi ntawm lubricant incorporation nyob rau hauv polymer yog txuam nrog compatibility ntawm lubricant thiab polymer, thiab cov compatibility nyob rau hauv lub molecular qauv ntawm lubricant thiab txheeb ze polymer polarity.Internal lubrication rau PVC, lubricant thiab plasticizer tuaj yeem suav tau tias yog cov khoom siv tib yam, tab sis qhov polarity ntawm qhov zawv zawg tus neeg saib xyuas yog tsawg, thiab kev sib raug zoo ntawm lubricant thiab PVC yog qis dua li ntawm plasticizer.Ob peb lub roj nplaum molecules tuaj yeem nkag mus ntawm cov molecules polymer, ua rau tsis muaj zog ntawm kev sib koom ua ke ntawm polymer molecules, ua kom yooj yim rau cov saw hlau polymer kom swb thiab tig nrog ib leeg thaum lub sij hawm deformation.

Lub ntsiab yam ntxwv ntawm lubricant yog hais tias nws muaj me me los yog txawm incompatibility nrog polymers.Nyob rau hauv cov txheej txheem ua, nws yog ib qho yooj yim rau extrude los ntawm cov khoom sib tov nyob rau hauv lub siab thiab tsiv mus nyob rau saum npoo los yog sab nraum lub interface ntawm cov khoom sib xyaw thiab ua machinery.Cov roj nplua nyeem molecules yog taw qhia thiab teeb tsa, thiab cov pawg polar ntsib cov hlau saum npoo los tsim cov txheej lubricating molecular los ntawm lub cev adsorption lossis tshuaj lom neeg daim ntawv cog lus.Vim yog lub zog cohesion qis ntawm cov roj nplaum molecules, Yog li ntawd, kev sib txhuam ntawm cov polymer thiab cov khoom siv saum npoo tuaj yeem raug txo kom tsis txhob ua raws li cov neeg kho tshuab nto.Lub viscosity ntawm lubricating zaj duab xis thiab nws cov lubrication efficiency nyob ntawm lub melting point thiab ua kub ntawm lubricant.Feem ntau, lubricants nrog ntev molecular chains muaj ntau dua lubrication nyhuv.
Polyethylene wax yog ib qho zoo hauv lubricant rau polyethylene thiab polypropylene.Nws tsis tau tag nrho nrog polyethylene wax, yog li nws plays lub luag hauj lwm lubrication sab nraud rau qee yam.Rau cov khoom loj txhaj tshuaj molded, siv quav ciab tuaj yeem tsis tsuas yog txhim kho cov fluidity hauv cov txheej txheem ua, tab sis kuj zoo heev txhim kho lub ntsej muag gloss thiab ib puag ncig kev ntxhov siab tawg.Ob leeg polyethylene thiab polypropylene yuav tsum muaj txog li 2% lubricant thiab qhia tias tsis muaj kev hloov pauv hauv kev ua haujlwm.Rau cov khoom siv rov ua dua tshiab, tuaj yeem ntxiv txog li 5% polyethylene wax thiab melt index tuaj yeem hloov mus rau qib uas yuav tsum tau ua.
3. Daim ntawv thov ntawm polyethylene wax hauv lwm cov teb
Polyethylene wax siv hauv tus cwj mem tuaj yeem muab kev sib txhuam, tiv thaiv khawb, tiv thaiv adhesion thiab khaws cov luster;Nws tseem tuaj yeem hloov pauv rheology ntawm tus number case thiab txhim kho hydrophilicity thiab luam ntawv kev ua tau zoo;Polyethylene wax feem ntau yog siv rau matting thiab nce tes xav hauv cov xim.Cov wax rau txheej yog tsuas yog ntxiv rau hauv daim ntawv ntawm additives.Nws yog Ameslikas siv los tiv thaiv kev ua haujlwm ntawm cov yeeb yaj kiab, feem ntau suav nrog kev txhim kho smoothness, khawb tsis kam thiab dej tsis zoo ntawm zaj duab xis.
