Specialty polyolefin elastomers (POE) uye polyolefin plastomers (POP), yakatanga kuunzwa kuti ivandudze zvimiro zve polyolefin senge kukanganisa uye kusimba kwesimba, dzakashanduka sedzinopindirana nekudzokororwa PE nePP, dzimwe nguva inoshandiswawo nezvimwe zvinhu zvakaita sePET kana PET.naironi.
Zvigadzirwa izvi zvinosanganisira Dow's Engage POE, OBC-yakapinza ethylene-alpha-olefin comonomer random copolymer, hard-soft block alternating olefin copolymer, uye Exxon Mobil Vistamaxx Propylene-Ethylene uye Exact Ethylene-Octene POP.
Zvigadzirwa izvi zvinotengeswa kune mapurasitiki anodzokorodza/makombindi uye mamwe magadzirirwo, akadaro Jesús Cortes, anovandudza musika paExxonMobil Product Solutions, achiona kuti kugarisana kunogona kuve chishandiso chekubatsira vanogadzira zvakare kushandisa kusvibisa-kusvibiswa uye zvinogona kudhura-mutengo wakaderera maajenti enzizi dze polyolefin.Han Zhang, Director weGlobal Sustainability for Packaging and Specialty Plastics kuThe Dow Chemical Company, akati: “Vatengi vedu vanobatsirwa nekugadzira chigadzirwa chemhando yepamusoro nekuwana nzira yakafara yekudzokorodza.Isu tinoshandira ma processors anoshandisa macompatibilizer kuti awedzere zvakadzokororwa zvemukati nekuchengetedza kugadzirwa. ”
"Vatengi vedu vanobatsirwa nekugadzira chigadzirwa chemhando yepamusoro apo vachiwana nzira yekudzokorora zvakare."
ExxonMobil 'Cortés yakasimbisa kuti iyo Vistamaxx uye Chaiyo mamakisi akakodzera mhandara resin gadziriso inogona zvakare kushandiswa kuve nechokwadi kuenderana nemapurasitiki akadzokororwa.Akataura kuti Vistamaxx mapolymers anoita HDPE, LDPE uye LLDPE ienderane nepolypropylene, achiwedzera kuti nekuda kweiyo polarity yemapolymers akadai sePET kana nylon, Vistamaxx giredhi grafting inodiwa kuti polyolefins ienderane nemapolymer akadaro."Semuyenzaniso, takashanda nevakawanda vanosanganisa kubatanidza Vistamaxx kuti polyolefins ienderane naironi tichivavarira kuchengetedza kuvandudzwa kwemaitiro ayo Vistamaxx mapolymers anogona kuunza mukuumbwa."

Kuenderana kunogona kusimbiswa neyakagadziridzwa michina zvivakwa, senge inodiwa zvakanyanya kukanganisa kuramba, sekureva kwaCortez.Kuwedzera fluidity kunokosha zvakare kana uchishandisa zvakare zvinhu.Muenzaniso kuvandudzwa kwemajekiseni ekuumba maumbirwo eHDPE bhodhoro hova.Anotaura kuti ese emhando elastomers aripo nhasi ane mashandisiro awo."Chinangwa chehurukuro hachisi chekuenzanisa kuita kwavo kwese, asi kusarudza chishandiso chakanakisa chechimwe chirongwa."
Semuenzaniso, akati, "Kana PE ichienderana nePP, isu tinotenda kuti Vistamaxx inopa mhedzisiro yakanaka.Asi musika unodawo kuvandudzwa kwemaitiro ekupikisa, uye ethylene-octene plastomers inogona kunge yakakodzera kana uchitsvaga kuderera kwekushisa.
Cortez akawedzera, "Ethylene-octene plastomers seyedu Chaiyo kana Dow's Engage mamakisi uye Vistamaxx ane mitoro yakafanana."
Dow's Zhang akatsanangura kuti nepo kuvapo kwepolypropylene muHDPE kunowanzo wedzera kuomarara sekuyerwa neflexural modulus, kunodzikisira zvivakwa sekuyerwa nekuoma uye kusimba kwehuremu nekuda kwekusawirirana kwezvikamu zviviri izvi.Kushandiswa kwevanopindirana mune izvi HDPE / PP kusanganiswa kunovandudza kuoma / viscosity chiyero nekuderedza kuparadzaniswa kwechikamu nekuvandudza kunamatira kwepakati.

Sekureva kwaZhang, Engage POE uye Infuse OBC inonyatsokodzera kuti HDPE, LDPE uye LLDPE ienderane nepolypropylene nekuda kwePE musana uye alpha-olefin comonomer.Sezvinowedzera zvePE/PP zvinosanganiswa, zvinowanzo shandiswa muhuwandu hwe2% kusvika 5% nehuremu.Zhang akacherekedza kuti nekuvandudza chiyero chekuomarara uye kuomarara, Batanidza POE anopindirana seGiredhi 8100 anogona kupa kukosha kwakawanda kune michina yakadzokororwa PE/PP masanganiswa, kusanganisira marara hova dzakakwirira muPE nePP.Zvishandiso zvinosanganisira jekiseni rakaumbwa zvikamu zvemotokari, magaba ependi, marashi, mabhokisi ekurongedzera, mapallets uye fenicha yekunze.
Musika unoda kuvandudzwa maitiro uye ethylene octene plastomers inogona kuita basa kana yakaderera tembiricha kukanganisa kuoma kunodiwa.
Akawedzera kuti: "Kuwedzerwa kwe3 wt chete.% Batanidza 8100 yakapetwa katatu simba rekukanganisa uye kusimba kwekurebesa kweiyo isingaenderane HDPE/PP 70/30 musanganiswa uchichengeta yakakwira modulus yakapihwa nechikamu chePP, "akawedzera, kune yakaderera tembiricha yepurasitiki, Engage POE inopa simba rinokanganisa pakupisa kwakadzika. nekuda kwekudzika kwakanyanya kwegirazi tembiricha yekuchinja.
Achitaura nezve mutengo weaya akasarudzika elastomers, ExxonMobil's Cortez akati: “Mumakwikwi ekudzokorodza kukosha kweketani, zvakakosha kuenzanisa mutengo nekuita.NeVistamaxx mapolymers, mashandiro emaresin akadzokororwa anogona kuvandudzwa, zvichibvumira marezeni kuti ashandiswe mumashandisirwo apo vanogadzirazve vanogona kuwana hupfumi hwepamusoro.pavanenge vachisangana nezvinodiwa zvezvigadzirwa zvepamusoro zvekushanda.Nekuda kweizvozvo, vanogadzirazve vanogona kuve nemikana mikuru yekutengesa mapurasitiki avo akadzokororwa, pane kungodhura semutyairi mukuru, achivabvumira kuti vatarise patsika dzakasanganiswa uye kuburikidza nekubuda.
