Waqtigan xaadirka ah, waxaa jira saddex nooc oo waaweyn oo hababka wax soo saarka loogu talagalayPE wax: Marka hore, wax polyetylen ah waxaa lagu farsameeyaa falcelinta oligomerization ee monomer ethylene, sida habka oligomerization xagjirka ah ee xorta ah;Midda labaad waa wax polyetylen ah oo ay diyaarisay hoos u dhaca polymers;Midda saddexaad waa wax-soo-saarka geeddi-socodka isku-dhafka ee polyetylen-ka, sida wax-soo-saarka polyetylen-ka oo la helay iyada oo la kala saarayo soo-saarka ee isku-dhafka polyetylen-ka-sare.

1. Habka polymerization Ethylene
Waxaa jira saddex hab oo waaweyn oo lagu soo saaro shamac polyetylen iyada oo loo marayo polymerization ethylene.Mid waa in polymerize iyadoo la isticmaalayo kicinta xagjirka xorta ah heerkulka sare iyo cadaadiska;Midda labaad waa in lagu sameeyo cadaadis hooseeya iyadoo la adeegsanayo kicinta Ziegler;Midda saddexaad waa polymerization of metallocene kicinta.
2. Habka dildilaaca polyetylen
Qaybinta miisaanka kelli eewax polyetylen ahoo ay soo saartay habka polymerization waa cidhiidhi, iyo cabbirka miisaanka molecular ee qaraabada ah ayaa lagu xakameyn karaa gacanta, laakiin waa in lagu sameeyaa qalab weyn oo leh maalgashi sare.Soosaarayaasha guduhu guud ahaan waxay isticmaalaan habka dildilaaca kulaylka ee polyetylen culeyska sare ee wax soo saarka.Habkani wuxuu u isticmaali karaa mid ka mid ah resin polyetylen ama caag qashinka polyetylen ah sida alaabta ceeriin.Midka hore wuxuu soo saaraa alaabo heer sare ah, halka kan dambe uu soo saaro alaabo heer hoose ah.Miisaanka unugyadu sareeyo ee polyetylen waxa uu si kulayl ahaan u dildilaaci karaa dhuxul-maleekulyareedka miisaanka yar ee xaaladaha go'doominta hawada.Tilmaamaha la xidhiidha qaab-dhismeedka wax-soo-saarka polyetylen-ka ee la diyaariyey, sida crystallinity, cufnaanta, qallafsanaanta, iyo barta dhalaalka, dhammaantood waxaa saameeya alaabta ceeriin ee dillaacsan.Hababka farsamaynta dildilaaca waxa loo qaybiyaa habka kiilka dildilaaca iyo habka extrusion.

Habka kettle dildilaaca waa hab farsamaysan oo kala go'a, oo ku habboon soosaarayaasha leh mugga wax-soo-saarka hooseeya iyo awoodda wax-soo-saarka yar;Habka extrusion waa hab-soo-saarka joogtada ah ee ku habboon shirkadaha leh mugga wax-soo-saarka iyo awoodda wax-soo-saarka sare.

Wax polyethylene waxaa lagu diyaarin karaa iyadoo la isticmaalayo xal dildilaaca polyetylen dib loo warshadeeyay.Farsamadani waxay leedahay ilo qani ah oo aan qaali ahayn oo laga helo alaabta ceeriin, hannaan fudud, iyo kharashyo hawleed oo hooseeya.
3. Sifaynta alaabta polyetylenka
Dareen-celinta soo saarista polyetylen-ka-soo-saarka ethylene polymerization, alaabta wax-soo-saarka polyetylen-ka waxaa laga soo ceshan karaa isku-darka qaybaha miisaanka kelliyada hoose iyo dareerayaasha la helay sida alaabta.Ka dib markii ay ka saareen dareeraha iyo bilawga ka soo baxa warshadda polyetylen, qaybinta miisaanka kelli ee alaabtu weli waa mid aad u ballaaran, taas oo xaddidaysa goobta codsiga waxayna u baahan tahay nadiifin dheeraad ah iyada oo loo marayo kala-soocidda dareeraha.Wax soo saarkan wax soo saarka polyetylen wuxuu inta badan ka kooban yahay unugyo leh culeys molecular oo qaraabo ah oo ku dhow 1000, sidaa darteed astaamihiisa jireed sida xoogga farsamada iyo caabbinta kulaylka ayaa ka hooseeya kuwa ay soo saarto polymerization ethylene.

4. Wax ka beddelka shayga polyetylenka
Wax polyethylene waa unug aan cirrid ahayn, haddii kooxaha polar la geliyo molecule-ka, waxay si weyn u ballaarin doontaa goobaha codsiga.Waxesyadan polyetylen-ka shaqeeya waxa lagu soo saari karaa iyada oo la koobiyeeyo ethylene oo leh monomers oksijiin ku jira, ama iyada oo la soo bandhigayo kooxaha karboksylka iyada oo loo marayo habab kiimikaad sida oksaydhka iyo tallaalka, ka dibna lagu sii beddelo falcelinta kiimikaad sida esterification, amided, iyo saponification.Waxyaalahan polyetylen-ka shaqeeyaa waxay buuxin karaan shuruudaha codsiyada kala duwan.
