Yintoni i-POE? Uhlalutyo olunzulu lweepropati kunye nokusetyenziswa kwayo
I-POE (i-Polyolefin Elastomer) yimathiriyeli yepolymer esetyenziswa kakhulu kwishishini lemichiza kwiminyaka yakutshanje. Ngokuqhubela phambili kwesayensi kunye nobuchwepheshe kunye nokwanda kwemfuno yemizi-mveliso, i-POE igqwesa kwiinkalo ezininzi ngenxa yeempawu zayo ezizodwa. Kule nqaku, siza kuxubusha ngokubanzi ukuba yiyiphi i-POE, kwaye sihlalutye iimpawu zayo, inkqubo yokuvelisa kunye neendawo zokusetyenziswa ukuze sincede abafundi baqonde ngakumbi ukubaluleka kwesi sixhobo.
Iipropati eziSisiseko ze-POE
Yintoni imathiriyeli yePOE? Ngokumalunga nokwakheka kweekhemikhali, i-POE yi-elastomer eyenziwe kwi-copolymerization ye-ethylene ene-copolymerising monomer, ngokuqhelekileyo i-α-olefin. Iimpawu zayo eziphambili zibandakanya ukuqina okugqwesileyo, ukuxinana okuphantsi, ukukhanya okuphezulu, kunye nemozulu entle kunye nokumelana nobushushu obuphantsi. Zezi zakhiwo ezivumela i-POE ukuba igqwese kuluhlu olubanzi lwezicelo, ngakumbi kwiimoto, izixhobo zokupakisha kunye nentambo yokushela.
Inkqubo yeMveliso yePOE
Ukuqonda ukuba yintoni i-POE, kubalulekile ukujonga inkqubo eveliswa ngayo, edla ngokuba yi-metallocene catalyst polymerisation. I-Metallocene catalysts zi-catalysts ezisebenzayo kakhulu ezivumela ulawulo oluchanekileyo lokusabalalisa ubunzima be-molecular ye-polymer kunye nokufakwa kwe-copolymer monomers. Le nkqubo iphumela ekuqhubekekeni okugqwesileyo kunye neempawu zemveliso ezingaguqukiyo kuluhlu olubanzi lweendlela zokusetyenzwa njengenaliti, i-extrusion kunye nokubumba ukuvuthela.
Iindawo ezisetyenziswayo eziphambili zePOE
Nje ukuba uyazi ukuba yintoni i-POE, ukuqonda iinkalo zokusetyenziswa kwayo kubalulekile ekuqondeni ngokupheleleyo izinto. Ngenxa ye-elasticity kunye nokuqina kwayo, i-POE isetyenziswe kwiintlobo ezininzi zezicelo zeemoto, ngokukodwa kwiimpawu zemoto, ii-bumpers kunye nezixhobo zangaphakathi.I-POE ephantsi yoxinaniso kunye nokungafihli nto yenza ukuba ilungele izinto zokupakisha eziphezulu, ezifana nefilimu yokupakisha ukutya. Izixhobo zokushela iintambo zekhebhu zikwayindawo ebalulekileyo yesicelo sePOE. Ngemozulu entle kunye nokumelana nobushushu obuphantsi, i-POE inokwandisa ngokufanelekileyo ubomi benkonzo yeentambo.
I-POE ngokuchasene nezinye ii-elastomers
Ukuze uqonde ngcono ukuba yintoni i-POE, sinokuyithelekisa nezinye i-elastomers eziqhelekileyo ezifana ne-TPU (i-thermoplastic polyurethane) kunye ne-EPDM (i-ethylene propylene diene rubber), enoxinano oluphantsi, ukuqhubekeka okuhle kunye neendleko eziphantsi. Kwaye xa kuthelekiswa ne-EPDM, i-POE yenza ngcono ngokumalunga nokusebenza okuphantsi kobushushu kunye nokungafihli. Ngenxa yoko, i-POE ihlala isetyenziswa njengenye imathiriyeli yokuphucula ukusebenza kwemveliso kunye nokunciphisa iindleko.
Isishwankathelo
Yintoni i-POE? Ukubeka ngokulula, i-POE yinto ephezulu yokusebenza kwe-elastomeric enoluhlu olubanzi lwezicelo. Ndiyabulela kwiimpawu zayo ezikhethekileyo, ezifana nokunwebeka okuphezulu, ukuxinana okuphantsi kunye nokusebenza kakuhle, i-POE ibonisa amandla amakhulu kwiindawo ezininzi. Nokuba kumashishini eemoto, kwishishini lokupakisha, okanye kwimveliso yentambo, i-POE ivula amathuba amatsha kwisayensi yezinto kunye nobunjineli.
Ngethemba, ngeli nqaku, abafundi baya kufumana ukuqonda ngokucacileyo ukuba yintoni i-POE kwaye kutheni ithatha indawo ebaluleke kangaka kwishishini lemichiza.
