Zitsanzo za HDPE/PP zobwezerezedwanso popanda Dow Engage compatibilizer (pamwamba) ndi zitsanzo za HDPE/PP Zobwezerezedwanso ndi Engage POE comptibilizer.Kugwirizana kuwirikiza katatu pakupuma kuchokera ku 130% mpaka 450%.(Chithunzi: Dow Chemical)
Pamene kukonzanso kwa mapulasitiki kukukhala msika womwe ukukula padziko lonse lapansi, ma resin ogwirizana ndi zowonjezera akugwiritsidwa ntchito kwambiri kuthana ndi zovuta za utomoni wosakanizidwa m'malo monga kulongedza ndi zinthu za ogula, zomangamanga, ulimi ndi magalimoto.Kupititsa patsogolo ntchito zakuthupi, kukonza kukonza ndi kuchepetsa ndalama komanso kuwononga chilengedwe ndi zina mwazovuta zazikulu, mapulasitiki ogula ambiri monga polyolefins ndi PET akutsogolera njira.
Chotchinga chachikulu chogwiritsa ntchito zinthu zobwezerezedwanso ndi kulekanitsidwa kodula komanso kowononga nthawi kwa mapulasitiki osagwirizana.Polola kuti mapulasitiki osagwirizana asungunuke, ogwirizanitsa amathandizira kuchepetsa kufunika kolekanitsa ndikuthandizira opanga zinthu kuti apange zinthu zapamwamba kwambiri, panthawi imodzimodziyo akuwonjezera zinthu zowonjezeredwa ndikupeza zatsopano zotsika komanso zotsika mtengo kuti achepetse ndalama.
Zophatikizanso zobwezerezedwansozi zimaphatikizapo ma elastomer apadera a polyolefin, ma styrenic block copolymers, ma polyolefin osinthidwa ndi mankhwala, ndi zowonjezera zochokera ku chemistry ya titanium aluminium.Zatsopano zina zawonekeranso.Onse akuyembekezeka kukhala pachiwonetsero chachikulu paziwonetsero zamalonda zomwe zikubwera.

Ma Specialty polyolefin elastomers (POE) ndi polyolefin plastomers (POP), omwe adayambitsidwa kuti apititse patsogolo mawonekedwe a ma polyolefin monga mphamvu komanso kulimba kwamphamvu, asintha ngati ogwirizana ndi PE ndi PP zobwezerezedwanso, nthawi zina amagwiritsidwanso ntchito ndi zida zina monga PET kapena PET.nayiloni.
Zogulitsazi zikuphatikiza Dow's Engage POE, OBC-yolowetsa ethylene-alpha-olefin comonomer mwachisawawa copolymer, hard-soft block alternating olefin copolymer, ndi Exxon Mobil Vistamaxx Propylene-Ethylene ndi Ethylene-Octene POP.
Zogulitsazi zimagulitsidwa kwa obwezeretsanso mapulasitiki / ophatikiza ndi ena obwezeretsanso, atero a Jesús Cortes, wopanga msika ku ExxonMobil Product Solutions, pozindikira kuti kuyanjana kungakhale chida chothandizira obwezeretsanso kugwiritsa ntchito makiyi owonongeka ndi omwe angakhale otsika mtengo pamitsinje ya polyolefin.A Han Zhang, Director of Global Sustainability for Packaging and Specialty Plastics ku The Dow Chemical Company, adati: "Makasitomala athu amapindula popanga chinthu chomaliza chapamwamba chomwe chimakhala ndi njira zambiri zobwezeretsanso.Timapereka mapurosesa omwe amagwiritsa ntchito zolumikizirana kuti awonjezere zomwe zidabwezerezedwanso ndikusunga kupanga. ”
"Makasitomala athu amapindula popanga chinthu chapamwamba kwambiri pomwe ali ndi mwayi wogwiritsa ntchito njira zambiri zobwezeretsanso."
ExxonMobil' Cortés yatsimikizira kuti Vistamaxx yemweyo ndi magiredi Enieni oyenera kusinthidwa kwa utomoni wa namwali zitha kugwiritsidwanso ntchito kuwonetsetsa kuti zimagwirizana ndi mapulasitiki obwezerezedwanso.Ananenanso kuti ma polima a Vistamaxx amapangitsa HDPE, LDPE ndi LLDPE kuti zigwirizane ndi polypropylene, ndikuwonjezera kuti chifukwa cha polarity ya ma polima monga PET kapena nayiloni, Vistamaxx grade grafting imafunika kuti ma polyolefin agwirizane ndi ma polima oterowo."Mwachitsanzo, tagwira ntchito ndi ophatikizira angapo kumezanitsa Vistamaxx kuti ma polyolefin azigwirizana ndi nayiloni pomwe tikufuna kupititsa patsogolo magwiridwe antchito omwe ma polima a Vistamaxx atha kubweretsa pakupanga."

Kugwirizana kumatha kutsimikiziridwa ndi makina opangidwa bwino, monga kukana kofunikira kwambiri, malinga ndi Cortez.Kuchulukitsa madzimadzi ndikofunikiranso mukamagwiritsanso ntchito zinthu.Chitsanzo ndi kakulidwe ka jekeseni wopangira jekeseni wa mitsinje ya mabotolo a HDPE.Amanenanso kuti ma elastomer apadera onse omwe alipo masiku ano ali ndi ntchito zawo."Cholinga cha zokambirana sikufananitsa ntchito yawo yonse, koma kusankha chida chabwino kwambiri cha polojekiti inayake."
Mwachitsanzo, adati, "Pamene PE imagwirizana ndi PP, timakhulupirira kuti Vistamaxx imapereka zotsatira zabwino kwambiri.Koma msika umafunikanso kulimba kwamphamvu, ndipo ma plastomers a ethylene-octene angakhale oyenera mukamayang'ana kulimba kwa kutentha.
Cortez anawonjezera kuti, "Ethylene-octene plastomers ngati magiredi athu enieni kapena a Dow's Engage ndi Vistamaxx ali ndi milingo yolemetsa yofanana."
Dow's Zhang adalongosola kuti ngakhale kupezeka kwa polypropylene mu HDPE nthawi zambiri kumawonjezera kuuma monga momwe kuyezedwera ndi flexural modulus, kumatsitsa katundu monga momwe amayesedwera ndi kulimba komanso kutalika kwamphamvu chifukwa cha kusagwirizana kwa zigawo ziwirizi.Kugwiritsiridwa ntchito kwa ma comptibilizer muzophatikizana za HDPE / PP kumapangitsa kuti kuuma / mamasukidwe akayendedwe bwino pochepetsa kulekanitsa gawo ndikuwongolera kumamatira kwapakati.

Malinga ndi Zhang, Engage POE ndi Infuse OBC ndizoyenera kwambiri kuti HDPE, LDPE ndi LLDPE zigwirizane ndi polypropylene chifukwa cha PE backbone ndi alpha-olefin comonomer.Monga zowonjezera pazophatikiza za PE / PP, zimagwiritsidwa ntchito pamlingo wa 2% mpaka 5% polemera.Zhang adanenanso kuti pakuwongolera kuuma komanso kulimba mtima, Engage POE comppatibilizers monga Giredi 8100 atha kupereka phindu lochulukirapo pakuphatikizana kwamakina a PE/PP, kuphatikiza mitsinje yazinyalala yomwe ili mu PE ndi PP.Mapulogalamuwa akuphatikiza zida zamagalimoto zopangidwa ndi jakisoni, zitini za penti, zinyalala, mabokosi oyikamo, mapaleti ndi mipando yakunja.
Msika umafunika kuwongolera magwiridwe antchito ndipo ma ethylene octene plastomers amatha kutengapo gawo pakafunika kutentha kwapang'onopang'ono.
Ananenanso kuti: "Kuwonjezera kwa 3 wt.% Engage 8100 kuwirikiza katatu mphamvu yakukhudzidwa ndi kukulitsa kosagwirizana kwa HDPE / PP 70/30 kuphatikiza ndikusunga modulus wapamwamba woperekedwa ndi gawo la PP, "adaonjeza, chifukwa cha kutentha kwapang'onopang'ono, Engage POE imapereka mphamvu pakutentha kozungulira. chifukwa chotsika kwambiri kutentha kwa galasi.
Polankhula za mtengo wama elastomer apaderawa, Cortez wa ExxonMobil adati: "Pampikisano wamtengo wapatali wobwezeretsanso, ndikofunikira kulinganiza mtengo ndi magwiridwe antchito.Ndi ma polima a Vistamaxx, magwiridwe antchito a resin obwezeretsedwa amatha kuwongolera, kulola kuti utomoni ugwiritsidwe ntchito pomwe obwezeretsa atha kupeza phindu lalikulu pazachuma. ”Pamene akukumana ndi kufunikira kwa zipangizo zamakono zogwirira ntchito.Chotsatira chake, obwezeretsanso amatha kukhala ndi mwayi waukulu wogulitsa mapulasitiki awo obwezeretsedwa, m'malo mongodula mtengo monga dalaivala wamkulu, zomwe zimawalola kuti aziyang'ana pa zosakanikirana ndi machitidwe."
