Yintoni imathiriyeli ye-HDPE? Uhlalutyo olubanzi lweempawu kunye nokusetyenziswa kwe-polyethylene ephezulu
Kwishishini lemichiza, i-HDPE yinto ebaluleke kakhulu, igama layo elipheleleyo yi-High-Density Polyethylene (i-High-Density Polyethylene). Yintoni kanye kanye i-HDPE? Eli nqaku liza kukunika impendulo ecacileyo kunye nohlalutyo olunzulu lweempawu ze-HDPE, inkqubo yayo yokuvelisa kunye noluhlu olubanzi lwezicelo.
Iingcamango ezisisiseko kunye noLwakhiwo lweMichiza ye-HDPE
Yintoni i-HDPE? Ukusuka kumbono weekhemikhali, i-HDPE yipolymer ye-thermoplastic eyenziwe ngokongezwa kwe-polymerisation ye-ethylene monomers. Isakhiwo sayo se-molecular ibonakaliswe ngamatyathanga e-polyethylene amade kunye nobunzima obuphezulu be-molecular mass kunye namatyathanga amancinci amancinci phakathi kwawo, okubangela ukulungelelaniswa kwe-molecular. Olu lungiselelo lwemolekyuli luqinile lunika i-HDPE ukuxinana okuphezulu kusapho lwe-polyethylene, phakathi kwe-0.940 g/cm³ kunye ne-0.970 g/cm³.
IiPropati eziPhezulu zoMzimba ze-HDPE
Izinto ze-HDPE zibonisa iimpawu ezininzi ezintle zomzimba ngenxa yesakhiwo sayo esisodwa se-molecular. Inamandla amakhulu kunye nokuqina kwaye inokumelana noxinzelelo oluphezulu lwemishini, eyenza ibe yinto egqwesileyo kwizicelo ezithwala imithwalo.I-HDPE inokumelana nemichiza egqwesileyo, eyenza ibe luncedo ekugcineni imichiza.
I-HDPE ikwanayo nokumelana nobushushu obuphantsi, ikwazi ukugcina ukuqina kwayo kwindawo ephantsi njenge -40 ° C ngaphandle kokuba brittle. Kananjalo ineempawu ezilungileyo zokugquma umbane, nto leyo ekhokelele ekusetyenzisweni kwayo kwi-sheathing yeengcingo kunye neentambo.
Inkqubo yokuvelisa i-HDPE kunye neendlela zokucubungula
Emva kokuqonda ukuba luhlobo luni lwezinto ezibonakalayo ze-HDPE, makhe sijonge inkqubo yayo yokuvelisa.I-HDPE idla ngokuveliswa yinkqubo ye-polymerisation yoxinzelelo oluphantsi, okt phantsi kweemeko eziphantsi zoxinzelelo, kunye ne-Ziegler-Natta catalyst okanye i-Phillips catalyst njengeyona nto iphambili, ngesigaba segesi, isisombululo okanye iindlela ze-polymerisation ezinodaka. Ezi nkqubo zikhokelela kwi-HDPE enekristali ephantsi kunye namazinga aphezulu e-crystallization, okukhokelela kwi-high density polyethylene material.
Izinto ze-HDPE zinokuqhubekeka kakuhle kwaye zinokubunjwa ngeendlela ezahlukeneyo zokusetyenzwa, njengokubumba inaliti, ukubunjwa kokuvuthela kunye nokubunjwa kwe-extrusion. Ngenxa yoko, i-HDPE inokwenziwa kwiintlobo ezininzi zeemveliso ezifana nemibhobho, iifilimu, iibhotile kunye nezikhongozeli zeplastiki.
Uluhlu olubanzi lweendawo zokusetyenziswa kwe-HDPE
Ngenxa yezinto ezininzi ezigqwesileyo zezinto ze-HDPE, isetyenziswa ngokubanzi kumashishini ahlukeneyo. Kwishishini lokupakisha, i-HDPE isetyenziswa ngokuqhelekileyo ekwenzeni iintlobo ezahlukeneyo zeebhotile zeplastiki, iibhotile zebhotile, iifilimu zokupakisha ukutya, njl njl. Kwishishini lokwakha, i-HDPE isetyenziselwa ukuvelisa unikezelo lwamanzi kunye nemibhobho yokuhambisa amanzi kunye nemibhobho yegesi, kwaye ukugqwala kwayo kunye nokuchasana kwempembelelo kwenza ukuba ithembeke kwiindawo ezibuhlungu.
Kwicandelo lezolimo, i-HDPE isetyenziselwa ukwenza iifilimu zezolimo, iminatha yomthunzi kunye nezinye iimveliso, apho ukuxhathisa kwayo kwe-UV kunye nokuqina kuqinisekisa ukukhuselwa kwezityalo kunye ne-yield.HDPE isetyenziselwa ngokubanzi ukuveliswa kwe-insulation yeingcingo kunye neentambo, kunye nakwiintlobo ezahlukeneyo zeetanki ezichasene nemichiza kunye nezikhongozeli.
Ukuqukumbela
I-HDPE yimathiriyeli ye-polymer ye-thermoplastic eneempawu ezibalaseleyo ezinjengokuqina okuphezulu, ukumelana neekhemikhali, ukumelana nobushushu obuphantsi kunye nokusebenza ngokulula. Inoluhlu olubanzi lwezicelo kwimichiza, ukwakhiwa, ezolimo kunye nezinye iindawo. Ukuba usacinga "yintoni impahla ye-HDPE", ngethemba lokuba ngeli nqaku, unokuqonda ngokubanzi iimpawu kunye nokusetyenziswa kwe-HDPE, i-HDPE ngokungathandabuzekiyo yenye yezinto ezisisiseko eziyimfuneko kwishishini lanamhlanje.
