polyethylene ciab yog hais txog qhov hnyav molecular polyethylene nrog cov txheeb ze molecular hnyav tsawg dua 10000, feem ntau muaj molecular hnyav li ntawm 1000 mus rau 8000. Polyethylene wax muaj cov khoom zoo heev thiab siv dav hauv number case, txheej, roj hmab ua, ntawv, textile, tshuaj pleev ib ce thiab lwm yam. teb.

Pe ciab muaj tshuaj zoo stability, zoo heev mechanical zog, hluav taws xob zog, dispersibility, fluidity thiab demoulding. Nws muaj qhov muag muag siab, qis melting viscosity, siab hardness thiab zoo hnav tsis kam. Raws li ib tug dispersant ntawm ntau yam masterbatches, ib tug demoulding tus neeg saib xyuas rau polyolefin ua, ib tug lubricant rau polychloroethylene yas ua, nws yog dav siv nyob rau hauv dav siv yas ua. Vim qhov kev taw qhia ntawm pawg polar, lub cev lub cev ntawm cov tshuaj hloov pauv polyethylene wax tau raug txhim kho, yog li daim ntawv thov teb ntawm polyethylene wax tau txuas mus rau engineering plastics nrog kev ua haujlwm siab dua thiab kev loj hlob sai.
Nyob rau hauv cov txheej txheem ntawm cov yas ua, polyethylene wax yuav siv tau raws li dispersant ntawm ntau yam masterbatches, ua lubricant ntawm ntau yam yas thiab compatibilizer ntawm ntoo yas composites. Nws yog ib qho kev pab cuam hauv kev lag luam yas.
1. Masterbatch dispersant
Nrog txoj kev loj hlob ntawm cov yas kev lag luam, kev lag luam yas kev lag luam nce zuj zus mus siv ntau yam kev ua haujlwm masterbatches nrog kev ua haujlwm yooj yim los txo cov nqi ntawm cov khoom siv raw thiab cov nqi txheej txheem, txhim kho kev tsim khoom, thiab muab cov khoom yas nrog cov khoom sib txawv rau ua tau raws li cov kev xav tau sib txawv ntawm kev ua lag luam.
Yas masterbatch mas suav nrog sau masterbatch, lubricating masterbatch, pob tshab masterbatch, pearlescent masterbatch, xim masterbatch thiab antistatic masterbatch. Cov yas masterbatch yog npaj los ntawm kev ntxiv cov yas ntxiv ntau dua li cov khoom siv rau hauv cov cab kuj. Yog li ntawd, tus masterbatch tuaj yeem ncaj qha ntxiv thaum tsim cov khoom yas.
Polyethylene wax tuaj yeem siv los ua dispersant xim masterbatch ntawm ntau yam thermoplastic resins thiab lubricating dispersant ntawm filling masterbatch thiab degradation masterbatch. Polyethylene wax muaj kev sib raug zoo nrog cov yas, zoo tiv thaiv tshav kub, zoo sib xyaw thiab yooj yim crushing, thiab tsis cuam tshuam rau kev ua tau zoo ntawm cov khoom siv davhlau ya nyob twg; Nws muaj peev xwm infiltrate, disperse thiab stabilize qhov hais ntawm muab tub lim los yog pigment. Cov kev tshawb fawb tau pom tias cov khoom siv polymerized polyethylene wax zoo dua li cov ntaub qhwv polyethylene hauv cov ntsiab lus ntawm ob qho tib si muaj peev xwm dispersion thiab thermal stability ntawm muab tub lim thiab pigment hais. Yog li ntawd, polymerized pe ciab feem ntau yog siv nyob rau hauv high-end masterbatch khoom, xws li SN9010W thiab SN118W ntawm Sainuo, uas muaj zoo dispersion thiab thermal stability nyob rau hauv lub masterbatch.

2. Plastic processing lubricant
Lub lubricant siv hauv kev ua cov yas yog los txhim kho cov fluidity thiab demoulding ntawm cov yas, tshwj xeeb tshaj yog cov thermoplastics, thaum ua thiab molding. Lub luag haujlwm tseem ceeb ntawm cov roj nplua nyeem yog txo qis kev sib txhuam ntawm cov ntaub ntawv yas thiab cov tshuab ua haujlwm thiab nruab nrab ntawm cov ntaub ntawv yas thiab cov molecules hauv cov txheej txheem ua, txhawm rau txhim kho kev ua haujlwm ntawm cov yas thiab txhim kho kev ua haujlwm ntawm cov khoom. Lub viscosity ntawm polyethylene wax yog qis dua li cov tshuaj yas. Nws tuaj yeem siv los ua cov yas yaj qhov ntsuas ntsuas ntsuas. Vim nws zoo thermal stability, tsis tshua muaj volatility ntawm qhov kub thiab zoo dispersion, nws muaj peev xwm txhim kho lub fluidity ntawm yas ua thiab txhim kho cov kev ua tau zoo ntawm cov yas.
Raws li kev ua haujlwm ntawm cov roj nplua nyeem hauv kev ua cov yas thiab molding, cov roj lubricants tau muab faib ua cov lubricants sab hauv thiab cov lubricants sab nraud. Lub lubricant sab hauv muaj qee yam kev sib raug zoo nrog cov polymer, thiab nws cov lubrication muaj nuj nqi yog los txo cov kev sib txhuam ntawm cov polymer molecules los yog txo cov quab yuam ntawm polar polymer molecules. Cov roj nplua nyeem sab nraud tsuas yog txo cov kev sib txhuam ntawm cov khoom siv polymer thiab cov tshuab ua haujlwm, uas tuaj yeem txhim kho kev ua haujlwm ntev, qhov ruaj khov, tiv thaiv scaling thiab ua kom muaj peev xwm ntau lawm. Muaj ntau hom roj nplua nyeem. Feem ntau cov lubricants muaj ob qho tib si sab hauv thiab sab nraud lubrication ua haujlwm. Ib qho uas muaj zog lubrication muaj nuj nqi yog hu ua lwm lubricant thiab ib tug muaj zog internal lubrication muaj nuj nqi hu ua internal lubricant.
Lubricants tau dav siv. Qee cov roj nplua nyeem yog siv los ua cov PVC, polyolefin, polystyrene, ABS, phenolic resin, melamine resin, cellulose acetate, unsaturated polyester, polyamide thiab roj hmab. Txawm li cas los xij, kev siv cov roj nplua nyeem tseem ceeb tseem nyob hauv PVC tawv, yog li cov neeg feem ntau tsom rau tawv PVC thaum ntsuas qhov ua tau zoo ntawm cov roj nplua nyeem.
3. PVC lubricant
PVC resin muaj lub cev zoo heev thiab tuaj yeem ua rau cov khoom tsis sib xws. Cov txheej txheem muaj xws li extrusion, txheej, txhaj tshuaj, tshuab moulding, calendering, thiab lwm yam. Cov khoom muaj xws li cov kav dej, profiles, nplooj ntawv, hollow cov khoom, hlau thiab cable sheaths, thiab lwm yam PVC resin muaj tsis zoo thermal stability, yog li nws yog ib qhov tsim nyog los ntxiv cov cua sov stabilizer thiab lubricant thaum ua. Cov roj nplua nyeem tuaj yeem tiv thaiv cov resin nyob hauv extruder los yog ua rau cov resin decomposition vim lub hauv paus overheating, thiab ua rau cov resin yooj yim tsim. PVC yas profiles yog dav siv nyob rau hauv tsev kho kom zoo nkauj profiles, lub tsev muab dej thiab cov kav dej thiab yas steel qhov rooj thiab qhov rais. Yas profile yog ua los ntawm PVC thiab ntau tshaj kaum hom yas additives los ntawm kev sib tov hloov thiab extrusion, thiab lubricant yog ib qho tseem ceeb additive.

polyethylene ciab yog tsuas yog siv rau sab nraud lubrication thiab muaj zog sab nraud lubrication. Nws kuj muaj lubricity zoo nyob rau hauv nruab nrab thiab tom qab theem ntawm molding ua. Nws tuaj yeem suav tias yog cov roj nplua nyeem nyob rau hauv nruab nrab thiab tom qab theem. Nws yog qhov tsim nyog rau kev tsim cov khoom lag luam nrog cov ntu complex. Nws tuaj yeem siv rau hauv cov hmoov lead ntsev stabilization system, uas tsis yog-tshuaj lom calcium thiab zinc puas stabilization system thiab tsis tshua muaj ntiaj teb sib xyaw stabilization system. Nws yog siv los ua cov ntaub ntawv kub-kub thiab muaj cov khoom tiv thaiv viscosity thiab tiv thaiv scorching zog. oxidized wax hmoov yog tsuas yog siv los ua cov roj nplaum sab nraud rau kev ua haujlwm nyuaj thiab mos PVC. Nws tuaj yeem txhim kho torque, txo cov nag lossis daus ntawm organotin thiab cov ntsev ntsev ruaj khov, muaj cov roj ntsha sab nraud siab heev thiab cov nyhuv demoulding, thiab tsis cuam tshuam rau Vicat thermal hloov kub thiab cuam tshuam lub zog ntawm cov khoom.
