A halin yanzu, akwai manyan nau'ikan hanyoyin samarwa guda uku donPE wani: da farko, polyethylene kakin zuma yana hade ta hanyar oligomerization amsawar ethylene monomer, kamar hanyar oligomerization na radical free;Na biyu shine polyethylene kakin da aka shirya ta hanyar lalata polymers;Na uku shine samfurin da ke cikin tsarin hada-hadar polyethylene, kamar polyethylene kakin da aka samu ta hanyar raba kayan aikin a cikin haɗin polyethylene mai ƙarfi.

1. Hanyar polymerization Ethylene
Akwai manyan hanyoyi guda uku don samar da kakin polyethylene ta hanyar ethylene polymerization.Ɗayan shine don yin polymerize ta amfani da masu haɓakawa na kyauta a babban zafin jiki da matsa lamba;Na biyu shi ne don yin polymerize a ƙarƙashin ƙananan matsa lamba ta amfani da Ziegler catalysts;Na uku shine polymerization na metallocene catalysts.
2. Hanyar fatattakar polyethylene
Rarraba nauyin kwayoyin halitta napolyethylene kakin zumawanda aka samar ta hanyar hanyar polymerization yana da kunkuntar, kuma ana iya sarrafa nauyin nauyin kwayoyin dangi da hannu, amma dole ne a yi shi a kan babban na'ura tare da babban zuba jari.Masana'antun cikin gida gabaɗaya suna amfani da hanyar fashewar thermal na babban nauyin kwayoyin polyethylene don samarwa.Wannan hanya na iya amfani da ko dai polyethylene resin ko polyethylene sharar gida a matsayin albarkatun kasa.Na farko yana samar da samfurori masu daraja, yayin da na ƙarshe ya samar da ƙananan samfurori.Polyethylene mai nauyin nauyin kwayoyin halitta yana iya fashe da zafi zuwa kakin polyethylene mara nauyi a ƙarƙashin yanayin keɓewar iska.Abubuwan da ke da alaƙa da tsarin da aka shirya da kakin zuma na polyethylene, irin su crystallinity, yawa, tauri, da kuma narkewa, duk suna shafar albarkatun ƙasa.Hanyoyin sarrafa fashe sun kasu kashi-kashi zuwa hanyar ƙulle-ƙulle da hanyar extrusion.

Hanyar kettle mai fashe hanya ce ta aiki ta tsaka-tsaki, wacce ta dace da masana'antun da ke da ƙarancin samarwa da ƙaramin ƙarfin samarwa;Hanyar extrusion ita ce ci gaba da samar da tsari wanda ya dace da kamfanoni tare da manyan nau'o'in samarwa da ƙarfin samar da kayayyaki.

Za a iya shirya kakin polyethylene ta hanyar amfani da maganin fatattakar polyethylene da aka sake yin fa'ida.Wannan fasaha tana da wadataccen tushen albarkatun ƙasa maras tsada, tsari mai sauƙi, da ƙarancin farashin aiki.
3. Tsabtace samfuran polyethylene
A cikin amsawar samar da polyethylene daga ethylene polymerization, ana iya dawo da samfuran polyethylene da kakin zuma daga cakuda ƙananan nauyin ƙwayoyin ƙwayoyin cuta da kaushi da aka samu azaman samfuran.Bayan cire sauran ƙarfi da mai farawa daga samfurin polyethylene shuka, rarraba nauyin kwayoyin halitta har yanzu yana da faɗi sosai, wanda ke iyakance filin aikace-aikacensa kuma yana buƙatar ƙarin tsarkakewa ta hanyar rabuwar ƙarfi.Wannan samfur na polyethylene kakin zuma yawanci yana ƙunshe da kwayoyin halitta masu nauyin kwayoyin halitta kusan 1000, don haka abubuwan da ke cikin jiki kamar ƙarfin injina da juriya na zafi sun yi ƙasa da waɗanda ethylene polymerization ke samarwa.

4. Gyaran kakin polyethylene
Polyethylene kakin sinadari ne wanda ba na iyakacin duniya ba, kuma idan za a iya shigar da kungiyoyin polar a cikin kwayoyin, zai fadada filayen aikace-aikacensa sosai.Ana iya samar da waɗannan nau'ikan polyethylene masu aiki ta hanyar copolymerization na ethylene tare da monomers masu ɗauke da iskar oxygen, ko kuma ta hanyar gabatar da ƙungiyoyin carboxyl ta hanyoyin sinadarai kamar oxidation da grafting, sannan kuma a ƙara inganta su ta hanyar halayen sinadarai kamar esterification, amidation, da saponification.Wadannan polyethylene waxes masu aiki zasu iya biyan bukatun aikace-aikace daban-daban.
