I-PE wax yenziwe ngani?

I-polyethylene waxiwuhlobo lwe-polyolefin yokwenziwa wax, ngokuvamile ebhekisela ku-homopolyethylene enesisindo samangqamuzana esihlobene esingaphansi kuka-10000. Ngomqondo obanzi, ama-polymers e-ethylene anamandla angenamandla kanye nokuqina futhi awakwazi ukucutshungulwa njengento eyodwa angabizwa ngokuthi i-polyethylene wax.Pe waxinephuzu eliphezulu lokuthambisa, i-viscosity encibilikayo ephansi, ukuzinza okuhle kwamakhemikhali, ukuthambisa okuhle kanye noketshezi.Njengosizo lokucubungula, isetshenziswa kabanzi kumapayipi e-PVC, amafilimu, izintambo neminye imikhiqizo yepulasitiki nenjoloba ukuze kuthuthukiswe ukusebenza kwemikhiqizo nokuthuthukisa ukubukeka kwemikhiqizo eqediwe.

Indlela yokulungiselela i-polyethylene wax
Kunezindlela ezintathu eziyinhloko zokwenziwa ze-pe wax.Eyokuqala yindlela yokuqhekeka kwe-polyethylene, ephula i-polyethylene resin ibe yi-polyethylene wax enesisindo esiphansi samangqamuzana ekushiseni okuphezulu.Okwesibili kuyindlela yokuhlanza ngomkhiqizo, eqoqa imikhiqizo yezingxenye eziphansi zesisindo samangqamuzana ezikhiqizwa inqubo yokukhiqiza i-ethylene polymerization futhi izihlanza ukuze zithole i-polyethylene wax.Indlela yesithathu i-ethylene synthesis method, ehlanganisa ngokuqondile i-polyethylene wax ne-ethylene njengento eluhlaza.Namuhla, i-Sainuo izokuthatha ukuthi ufunde mayelana ne-polyethylene wax elungiselelwe indlela yokuqhekeka kanye nendlela yokuhlanganisa.

(1) Ukulungiswa kwe-polyethylene wax nge-pyrolysis
Indlela yokuqhekeka iyindlela eyinhloko yokukhiqiza i-polyethylene wax eChina.Isisindo samangqamuzana aphezulu i-polyethylene ehlanzekile noma ipulasitiki ye-polyethylene eyimfucuza iqhekeka ibe yi-polyethylene wax ekushiseni okuphezulu.Izinga lomkhiqizo walo kanye nezakhiwo (njengokuqina, indawo encibilikayo kanye nombala obonakalayo) kuthinteka kakhulu umthombo wokuqhekeka kwezinto zokusetshenziswa.Indlela yokuqhekeka inobuchwepheshe obulula, umthombo ocebile wezinto ezingavuthiwe kanye nezindleko eziphansi zokusebenza.Ingabona ukusetshenziswa kabusha kwe-polyethylene engcolile enezinzuzo ezinhle zezomnotho.Kodwa-ke, inqubo yokuqhekeka inzima ukuyilawula, ukusatshalaliswa kwesisindo se-molecular yomkhiqizo kubanzi, ikhwalithi ye-polyethylene wax kunzima ukuyilawula, futhi amabala amaningi amnyama akhiqizwa.Idumile phakathi nezinhlelo zokusebenza ezisezingeni eliphansi njenge-color masterbatch.
Izinqubo ezikhona zokuqhekeka zifaka ukuqhekeka okushisayo, ukuqhekeka okusizwa kwe-solvent kanye nokuqhekeka kwe-catalytic.Phakathi kwazo, ukuqhekeka okushisayo kulula kakhulu.Imikhiqizo ye-wax ye-polyethylene ingalungiswa ngokulawula izinga lokushisa lokuphendula kanye nesikhathi, kodwa ukusetshenziswa kwamandla kuyadingeka.Abantu baseBeijing University of chemical technology baye bafunda ukulungiswa kwe-polyethylene wax ngokuqhekeka i-PE resin ekushiseni okuphezulu ku-extruder eyodwa yesikulufu.Ihitha yengezwa epayipini elixhumayo phakathi kwe-extruder nethangi lokupholisa ukuze kushiswe futhi kuqhekezwe impahla.Izinga lokushisa elilungile lokuqhekeka lingu-420 ℃, liqaphela ukukhiqizwa okuqhubekayo kokuqhekeka kwe-PE resin ukulungisa i-polyethylene wax.Abanye baye bafunda ukulungiswa kwe-polyethylene wax ngokuphahlaza i-polyethylene yemfucuza ku-autoclave ene-al-mcm-48 njenge-catalyst.Izinga lokushisa lokusabela lingu-360 ~ 380 ℃ futhi isikhathi sokusabela ngu-4H.Ukusetshenziswa kwe-catalyst kunciphisa amandla okwenza kusebenze, izinga lokushisa elidingekayo ku-pyrolysis kanye nokusetshenziswa kwamandla.U-Wang Lulu nabanye bathuthukisa isivuno se-polyethylene wax nge-solvent assisted pyrolysis yamapulasitiki emfucuza e-polyethylene.Imiphumela yezinyibilikisi ezihlukene kanye nezimo zokusabela kwisivuno kanye nezakhiwo ze-wax zaphenywa.Ukuhlolwa kubonisa ukuthi isivuno se-wax ye-polyethylene singathuthukiswa ngokusebenzisa izincibilikisi ezinuka kamnandi.Uma usebenzisa i-xylene exubile njenge-solvent, isivuno sifinyelela ku-87.88%.Izinyibilikisi ezinuka kamnandi zingaphinde zithuthukise ikhwalithi yomkhiqizo ngokwezinga elithile futhi zithole i-wax ye-polyethylene ephuzi ekhanyayo.

(2) Ukuhlanganiswa kwe-polyethylene wax
I-polyethylene wax ehlanganiswe ngokuqondile esuka ku-ethylene inokuhlanzeka okuphezulu, ukusatshalaliswa kwesisindo samangqamuzana amancane, uhla oluncibilikayo oluncane, ukusebenza komkhiqizo okulungiswayo kanye nekhwalithi ezinzile.Isetshenziselwa ukukhiqiza i-wax ye-polyethylene esezingeni eliphezulu futhi ehlukahlukene.Ngokusho komshini we-polymerization kanye nezinhlobo zama-catalysts asetshenzisiwe, i-ethylene synthesis ingahlukaniswa ibe yi-polymerization yamahhala ye-radical, i-Ziegler Natta (ZN) i-catalytic polymerization, i-metallocene catalytic polymerization nokunye.
Le nkampani Qingdao Sainuo Chemical Co., Ltd.Singabakhiqizi be-PE wax, i-PP wax, i-OPE wax, i-EVA wax, i-PEMA, i-EBS, i-Zinc/Calcium Stearate….Imikhiqizo yethu iphumelele ukuhlolwa kwe-REACH, ROHS, PAHS, FDA.
