Iyini i-High Density Polyethylene

High density polyethylene (HDPE), powder emhlophe noma umkhiqizo granular. Okungeyona ubuthi, okunganambitheki, okucwebezelayo okungama-80% kuya ku-90%, indawo yokuthambisa engu-125 kuya ku-135°C, sebenzisa izinga lokushisa elifika ku-100°C; ubulukhuni, amandla okuqina kanye ne-ductility kungcono kune-polyethylene ephansi; ukumelana nokugqoka, ugesi Ukufakwa kahle, ukuqina kanye nokumelana nokubanda; ukusimama okuhle kwamakhemikhali, okungancibiliki kunoma iyiphi i-solvent ephilayo ekamelweni lokushisa, ukumelana nokugqwala kwe-asidi, i-alkali nosawoti ohlukahlukene; ifilimu elincanyana permeability kumhwamuko wamanzi nomoya, ukumuncwa amanzi Low; ukumelana nokuguga okumpofu, ukumelana nokucindezeleka kokucindezeleka kwemvelo akufani ne-polyethylene ephansi, ikakhulukazi i-oxidation eshisayo izonciphisa ukusebenza kwayo, ngakho-ke ama-antioxidants kanye nama-absorber ultraviolet kumele kwengezwe ku-resin ukuze kuthuthukiswe lokhu kuntuleka. Ifilimu ye-polyethylene ephezulu kakhulu inokushisa okuphansi kokuhlanekezela ukushisa ngaphansi kwengcindezi, ngakho-ke yinake lapho uyisebenzisa.

[Igama lesiNgisi] I-High Density Polyethylene
[isifinyezo sesiNgisi] HDPE
[Igama elivamile] I-ethylene enengcindezi ephansi
[I-monomer yokwakhiwa] I-Ethylene

[Izici eziyisisekelo] I-HDPE i-opaque emhlophe efana ne-wax ene-gravity ethize elula kunamanzi, enobunzima obuthile obungu-0.941~0.960. Ithambile futhi iqinile, kodwa ilukhuni kancane kune-LDPE, futhi futhi iyanwebeka kancane, ayinabo ubuthi futhi ayinambitheki.

[Izici zomlilo] Iyavutha futhi ingaqhubeka nokuvutha ngemva kokushiya umlilo. Ingxenye engenhla yelangabi iphuzi kanti ingxenye engezansi iluhlaza okwesibhakabhaka. Lapho isha, izoncibilika, kuyoba khona uketshezi oluconsayo, futhi akukho ntuthu emnyama ezophuma. Ngesikhathi esifanayo, ikhipha iphunga lokushiswa kukapharafini.

[Izinzuzo Eziyinhloko] Ukumelana ne-Acid ne-alkali, ukumelana ne-solvent yemvelo, ukwahlukanisa ugesi okuhle kakhulu, futhi kusengagcina ukuqina okuthile ekushiseni okuphansi. Ukuqina kobuso, amandla aqinile, ukuqina namanye amandla emishini aphakeme kune-LDPE, eduze ne-PP, aqinile kune-PP, kodwa ukuqedwa okungaphezulu akukuhle njenge-PP.

[Ububi obuyinhloko] Izakhiwo ezingezinhle zemishini, umoya ongemuhle, ukuwohloka kalula, ukuguga kalula, ukuba brittle, ukonakala kancane kune-PP, ukuqhekeka okulula ukukugcizelela, ubulukhuni obuphezulu obuphansi, ukunwaya kalula. Kunzima ukuphrinta, lapho ukuphrinta, ukwelashwa kokukhishwa kwamanzi kuyadingeka, akukho electroplating, futhi ubuso buthuntu.

[Izinhlelo zokusebenza] Isetshenziselwa amafilimu okupakisha e-extrusion, izintambo, izikhwama ezilukiwe, amanetha okudoba, amapayipi amanzi; ukubumba umjovo wezidingo zansuku zonke zezinga eliphansi namagobolondo, izingxenye ezingathwali mthwalo, amabhokisi epulasitiki, amabhokisi okwenza inzuzo; izitsha zokubumba i-extrusion blow, imikhiqizo engenalutho, amabhodlela.
