Popanga polyethylene, mafuta ochepa a oligomer amapangidwa, ndiye kuti, polyethylene yocheperako ya molekyulu, yomwe imadziwikanso kuti sera ya polima, kapenaphula la polyethylenemwachidule.Sera ya polima ndi yopanda poizoni, yosakondera, yosawononga, yoyera kapena yachikasu pang'ono yokhala ndi molekyulu yolemera 1800 ~ 8000. Itha kupangidwa kukhala midadada, flakes ndi ufa ngati pakufunika.Pakupanga kwabwinobwino, gawo ili la sera litha kuwonjezeredwa mwachindunji ku polyolefin ngati chowonjezera, ndipo limakhala ndi kukana kuzizira kwambiri, kukana kutentha, kukana mankhwala komanso kukana kuvala.
Popanga sera ya polyethylene, kuwongolera kutentha kwanthawi yayitali ndi nthawi ndikofunikira kuonetsetsa kuti katundu ndi mtundu wa sera yosweka.Kutentha kwakukulu kumafuna kupitirira 300 ℃.Ngati kutentha kuli kochepa kwambiri, kuwonongeka sikukwanira, unyolo wa maselo sungathe kusweka, ndipo madzi amadzimadzi ndi osauka, omwe sakugwirizana ndi ntchito zosiyanasiyana;Kutentha kumakhala kokwera kwambiri, mphamvu yogwiritsira ntchito mphamvu ndi yaikulu kwambiri, mtengo wopangira ukuwonjezeka, madzi amadzimadzi amathamanga kwambiri, nthawi yozizira imakhala yayitali kwambiri, ndipo kutulutsa kumathamanga kwambiri, zomwe zimakhala zosavuta kuyambitsa kuyaka ndi ngozi.Kuphatikiza apo, kutulutsa kozungulira koziziritsa kumayenera kukhala kwangwiro.Ngati kuzizira kwa chipangizocho kuli kocheperako, sera ya polyethylene imawonekera kutentha kwambiri mumlengalenga, zomwe zimakhala zosavuta kukhala oxidized, ndipo mankhwalawa ndi imvi.Kutentha kotulutsa kuyenera kuyendetsedwa pansi pa 800 ℃.

Kugwiritsa ntchito polyethylene sera
1. Kugwiritsa ntchitopa wax ngati dispersant
Sera ya polyethylene ndi mtundu wamafuta komanso wotulutsa wokhala ndi mafuta abwino akunja.Kuwonjeza pa mphira ndi mapulasitiki kumatha kuwongolera magwiridwe antchito, kukonza gloss pamwamba ndi kukana kuvala kwa zinthu, kumathandizira kubalalitsidwa kwa zodzaza ndi utoto, komanso kugwiritsidwa ntchito ngati zopangira za pulasitiki wachikuda.
Kugwiritsa ntchito sera ya polyethylene mu Colour Masterbatch
Sera ya polyethylene imagwiritsidwa ntchito kwambiri pokonza mtundu wa masterbatch.Cholinga chowonjezera sera ya polyethylene sikungowonjezera kusinthika kwa mtundu wa masterbatch, komanso kulimbikitsa kubalalitsidwa kwa pigment mu mtundu wa masterbatch.Kubala kwa pigment ndikofunikira kwambiri kwa mtundu wa masterbatch.Ubwino wa Colour Masterbatch makamaka umadalira kupezeka kwa pigment.Pigment dispersing ndi lustrous masterbatch ali ndi mphamvu zopaka utoto, mtundu wabwino komanso mtengo wotsika wa utoto.Sera ya polyethylene imatha kusintha kuchuluka kwa mtundu wa pigment kumlingo wina.Ndi dispersant wamba pakupanga mtundu masterbatch.

2. Kugwiritsa ntchito sera ya polyethylene ngati mafuta
Sera ya polyethylene ndi mtundu wamafuta komanso wotulutsa wokhala ndi mafuta abwino akunja.Kuwonjezera pa mphira ndi mapulasitiki kungathandize kukonza bwino ntchito ndi gloss pamwamba ndi kuvala kukana kwa zinthu.
Njira yochitira: ntchito yamafuta ndikuchepetsa kukangana pakati pa kukhudzana pakati pa polima ndi makina opangira zinthu komanso pakati pa unyolo wa ma cell a polymerized.Choyamba chimatchedwa mafuta akunja ndipo chotsirizirachi chimatchedwa mafuta amkati.Mafuta amkati ndi polima ali ndi kugwirizana kwina.Pa kutentha kwa chipinda, kugwirizanitsa kumakhala kochepa, pamene kutentha kwakukulu, kugwirizana kumawonjezeka molingana.Mlingo wa kuphatikizika kwa mafuta mu polima umagwirizana ndi kugwirizana pakati pa mafuta ndi polima, ndipo kuyanjana kumatengera kapangidwe kake ka mafuta ndi wachibale wa polima polarity.Internal kondomu kwa PVC, lubricant ndi plasticizer akhoza kuonedwa ngati zinthu zomwezo, koma polarity wa dzenje kutsetsereka wothandizila ndi otsika, ndi ngakhale pakati lubricant ndi PVC ndi wotsika kuposa plasticizer.Mamolekyu ochepa opaka mafuta amatha kulowa pakati pa mamolekyu a polima, kufooketsa kukopana kwa mamolekyu a polima, kupangitsa kuti maunyolo a polima azitha kusuntha ndikuzungulirana wina ndi mnzake panthawi yopindika.

Khalidwe lalikulu la mafuta odzola ndikuti ali ndi zochepa kapena zosagwirizana ndi ma polima.Pokonza ndondomeko, n'zosavuta kutulutsa kuchokera kuzinthu zosakanikirana pansi pa kupanikizika ndikusamukira kumtunda kapena kunja kwa mawonekedwe pakati pa zipangizo zosakanikirana ndi makina opangira.Mamolekyu amafuta amakhazikika ndikukonzedwa, ndipo magulu a polar amayang'anizana ndi chitsulo pamwamba kuti apange mafuta osanjikiza ma cell kudzera pakutsatsa kapena kugwirizanitsa mankhwala.Chifukwa otsika mgwirizano mphamvu pakati mamolekyu lubricant, Choncho, kukangana pakati polima ndi zipangizo pamwamba akhoza kuchepetsedwa kuteteza kuti asamamatire pamwamba makina.The mamasukidwe akayendedwe a lubricant filimu ndi kondomu yake dzuwa zimadalira pa kusungunuka ndi processing kutentha kwa lubricant.Nthawi zambiri, mafuta okhala ndi maunyolo aatali a molekyulu amakhala ndi zokometsera kwambiri.
Sera ya polyethylene ndi mafuta abwino amkati a polyethylene ndi polypropylene.Sizogwirizana kwathunthu ndi sera ya polyethylene, chifukwa chake imakhala ndi gawo lakunja lopaka mafuta pamlingo wina.Pakuti lalikulu mankhwala jekeseni kuumbidwa, sera akhoza kusintha fluidity mu ndondomeko processing, komanso kwambiri patsogolo gloss ndi chilengedwe nkhawa akulimbana kukana.Zonse za polyethylene ndi polypropylene ziyenera kukhala ndi mafuta ofikira 2% ndipo siziwonetsa kusintha kwa magwiridwe antchito.Pazinthu zobwezerezedwanso, mpaka 5% sera ya polyethylene ikhoza kuwonjezeredwa ndipo index yosungunuka imatha kusinthidwa kuti ikhale yofunikira.
3. Kugwiritsa ntchito sera ya polyethylene m'madera ena
Sera ya polyethylene yomwe imagwiritsidwa ntchito mu inki imatha kupereka anti friction, anti scratch, anti adhesion ndi kusunga kuwala;Ikhozanso kusintha rheology ya inki ndikuwongolera hydrophilicity ndi ntchito yosindikiza;Sera ya polyethylene imagwiritsidwa ntchito kwambiri pokwerera ndikuwonjezera kumveka kwa manja papenti.Sera ya kupaka imawonjezeredwa makamaka mu mawonekedwe a zowonjezera.Poyambirira idagwiritsidwa ntchito poletsa kufalikira kwa filimuyi, makamaka kuphatikiza kuwongolera bwino, kukana zikande komanso kusalowa madzi kwa filimuyo.
