Okwangoku, kukho iintlobo ezintathu eziphambili zeendlela zokuvelisaPE wax: okokuqala, i-polyethylene wax yenziwe nge-oligomerization reaction ye-ethylene monomer, njenge-free radical oligomerization method;Okwesibini i-wax ye-polyethylene elungiselelwe ukuthotywa kweepolymers;Okwesithathu yi-byproduct kwinkqubo yokwenziwa kwe-polyethylene, efana ne-polyethylene wax efunyenwe ngokuhlula i-byproduct kwi-high-pressure polyethylene synthesis.

1. Indlela ye-ethylene polymerization
Kukho iindlela ezintathu eziphambili zokuvelisa i-polyethylene wax ngokusebenzisa i-ethylene polymerization.Enye kukwenza iipolymerize usebenzisa i-free radical catalysts kubushushu obuphezulu kunye noxinzelelo;Okwesibini kukwenza i-polymerize phantsi koxinzelelo oluphantsi usebenzisa i-Ziegler catalysts;Okwesithathu yi-polymerization ye-metallocene catalysts.
2. Indlela yokuqhawula i-polyethylene
Ukuhanjiswa kobunzima bemolekyuli yepolyethylene waxeveliswa yi-polymerization indlela imxinwa, kwaye ubungakanani bobunzima bemolekyuli bunokulawulwa ngesandla, kodwa kufuneka lwenziwe kwisixhobo esikhulu kunye notyalo-mali oluphezulu.Abavelisi basekhaya ngokuqhelekileyo basebenzisa indlela yokuqhekeka kwe-thermal ye-polyethylene ephezulu ye-molecular weight for production.Le ndlela inokusebenzisa i-polyethylene resin okanye iplastiki yenkunkuma ye-polyethylene njengento ekrwada.Eyangaphambili ivelisa iimveliso zodidi oluphezulu, ngelixa le yokugqibela ivelisa iimveliso ezikumgangatho ophantsi.I-polyethylene ephezulu yobunzima bemolekyuli inokuqhekeka ngokushushu kwi-molecular weight polyethylene wax phantsi kweemeko zokuhlukaniswa komoya.Iipropati ezinxulumene nesakhiwo se-wax ye-polyethylene elungiselelwe, njenge-crystallinity, ubuninzi, ukuqina, kunye ne-melting point, zonke zichaphazelekayo ngokukrazula izinto eziluhlaza.Iindlela zokucubungula ukuqhekeka zihlulwe ngendlela yeketile yokuqhekeka kunye nendlela yokukhupha.

Indlela yokuqhawula i-kettle yindlela yokucubungula i-intermittent, ilungele abavelisi abanomthamo ophantsi wokuvelisa kunye nomthamo omncinci wokuvelisa;Indlela ye-extrusion yinkqubo yokuvelisa eqhubekayo efanelekileyo kumashishini anemiqulu emikhulu yokuvelisa kunye nomthamo ophezulu wemveliso.

Iwax yePolyethylene inokulungiswa ngokusebenzisa isisombululo sokuqhekeka se-polyethylene esetyenzisiweyo.Obu bugcisa bunomthombo otyebileyo nongabizi kakhulu wezinto ezisetyenziswayo, inkqubo elula noko, kunye neendleko zokusebenza eziphantsi.
3. Ukucocwa kweemveliso ze-polyethylene
Ekuphenduleni ukuvelisa i-polyethylene kwi-ethylene polymerization, iimveliso ze-wax ze-polyethylene zinokufunyanwa kumxube wamacandelo aphantsi obunzima be-molecular kunye ne-solvents ezifunyenwe njengemveliso.Emva kokususa i-solvent kunye ne-initiator kwi-by-product yesityalo se-polyethylene, ukusabalalisa ubunzima be-molecular yemveliso kusebanzi kakhulu, okukhawulela intsimi yesicelo kwaye kufuna ukuhlanjululwa okuqhubekayo ngokuhlukana kwe-solvent.Le byproduct ye-wax ye-polyethylene ihlala iqulethe iimolekyuli ezinobunzima be-molecular malunga ne-1000, ngoko ke iimpawu zayo ezibonakalayo ezifana namandla omatshini kunye nokumelana nobushushu zingaphantsi kunezo ziveliswa yi-ethylene polymerization.

4. Ukuguqulwa kwe-polyethylene wax
I-polyethylene wax i-molecule engekho-polar, kwaye ukuba amaqela e-polar angafakwa kwi-molecule, iya kwandisa kakhulu imimandla yesicelo sayo.Ezi polyethylene wax ezisebenzayo zinokuveliswa nge-copolymerization ye-ethylene ene-monomers eneoksijini, okanye ngokwazisa amaqela e-carboxyl ngeendlela zekhemikhali ezifana ne-oxidation kunye nokuxhunyelelwa, kwaye emva koko ihlaziywe ngokuphendula kweekhemikhali ezifana ne-esterification, amidation, kunye ne-saponification.Ezi polyethylene wax ezisebenzayo zinokuhlangabezana neemfuno zezicelo ezahlukeneyo.
