Yintoni i-HDPE? Uhlalutyo olubanzi lweempawu kunye nokusetyenziswa kwe-pronithylene
Kumzi-mveliso wekhemikhali, i-HDPE yinto ebaluleke kakhulu, igama layo elipheleleyo lingu-Pollithylene (i-pronithylene). Yintoni kanye kanye i-HDPE? Eli nqaku liza kukubonelela ngempendulo eneenkcukacha kunye nohlalutyo olunzulu lweempawu ze-HDPE, inkqubo yazo kunye noluhlu lwayo lwezicelo.
Iikhonsepthi ezisisiseko kunye neWalela yeKhemikhali yeHDPE
Yintoni i-HDPE? Ukusuka kwindawo yemichiza yekhemikhali, i-HDPE yi-thermoplastic polymer eyenziwe ngokudibanisa i-polymerication ye-polymeries ye-Ethylene. Isakhiwo sayo semolekyuli siphawulwa ziikhonkco ezinde ze-polyethylene kunye ne-suble ye-molecular yesilinganisi kunye namakhonkco aphantsi aphantsi phakathi kwawo, ezikhokelela kwilungiselelo lokuqina kwemolekyuli. Olu hlaziyo luqinileyo lwemolekyuli lunika i-HDPE i-hip losapho lePolithylene, iphakathi phakathi kwe-0.940 G / CM³ kunye ne-0.970 g / cm³.
Iipropathi ezingaphezulu ze-HDPE
Izixhobo ze-HDPO zibonisa iipropathi ezininzi ezibalaseleyo zomzimba ngenxa yesakhiwo sayo esikhethekileyo semolekyuli. Inamandla aphezulu kunye nobungqola kwaye inokumelana noxinzelelo oluphezulu lwendlela, eyenza ilunge ngakumbi kwizicelo zokulayisha umthwalo.
I-HDPE ikwanokunyangeka okusemazantsi kobushushu, okwazi ukugcina ubugqwetha kwezona ndawo ziphantsi njenge-40 ° ngaphandle kokufumana brittle. Ikwanazo nezinto ezilungileyo zoMbane, ezikhokelele ekusebenziseni kwayo ekucandeni kweengcingo kunye neentambo.
Inkqubo yemveliso ye-HDPE kunye neendlela zokulungisa
Emva kokuqonda ukuba loluphi uhlobo lwe-HDPE yezinto ezibonakalayo, masijonge inkqubo yayo yemveliso.HDPE idla ngokuveliswa yinkqubo yoxinzelelo oluphantsi, okt phantsi kweemeko zoxinzelelo oluphantsi, okt phantsi kweemeko zoxinzelelo olusezantsi, nge-pillips ye-catalyst njengeyona nto iphambili, isigaba segesi, isisombululo segesi okanye ukutyhola ngeendlela ze-Polymerisation. Ezi nkqubo zikhokelela kwi-HDPE kunye ne-crystallity ephantsi kunye namanqanaba aphezulu e-crystallisation, obangelwa kukuxinana okuphezulu kwePolythylene.
Izinto ze-HDPE zinemisebenzi elungileyo kwaye zinokubunjwa ziindlela ezahlukeneyo zokulungisa, ezinjengokutsala isithsaba, ukubetha nokubumba kunye nokuphuma. Ngenxa yoko, i-HDPE inokwenziwa ngeendlela ezininzi zeemveliso ezinje ngemibhobho, iifilimu, iibhotile kunye nezikhongozeli zeplastiki.
Uluhlu olubanzi lweendawo zesicelo kwi-HDPE
Ngenxa yezinto ezininzi ezilungileyo zezinto ze-HDPE, isetyenziswa ngokubanzi kumashishini ahlukeneyo. Kumzi-mveliso wokupakisha, i-HDP isetyenziswa ngokuqhelekileyo ekwenzeni iintlobo ezahlukeneyo zeebhotile zeplastiki, iifilimu zokufaka ukutya, njl njl. Kumzi-mveliso wokwakha, i-HDPE isetyenziselwa ukwenza umbhobho wamanzi kunye nemibhobho yokuntywila kunye nemibhobho yegesi, kunye nokungavisisani kwegesi kunye nokungaxhathisi kwempembelelo kwenza ukuthembeka kwiindawo ezinobunzima.
Kwicandelo lezolimo, i-HDPI isetyenziselwa ukwenza iifilimu zezolimo, iminatha eshaza kunye nezinye iimveliso, apho kuchaswa khona iimveliso ze-UV kwaye kuqinisekiswe ngokubanzi ekwenziweni kweengcingo zeengcingo kunye neentambo, ngokunjalo iintlobo ezahlukeneyo zeetanki ezinganyangekiyo kunye nezikhongozeli.
Ukuqukumbela
I-HDPE yi-Thermoplastic Polymer yezinto ezinepropathi ebalaseleyo efana namandla aphezulu, ukuxhathisa amachiza, ukuxhathisa kobushushu obuphantsi kunye nokusebenza ngokulula. Inoluhlu olubanzi lwezicelo kwikhemikhali, ulwakhiwo, ezolimo kunye namanye amasimi. Ukuba usacinga ukuba "yintoni le mpahla ye-HDPE", unethemba lokuba ngeli nqaku, unokuqonda okubanzi kweempawu kunye nokusetyenziswa kwe-HDPE, i-HDPE ngokungathandabuzekiyo kwezixhobo ezisisiseko kwishishini.
