Okuthile mayelana ne-UHMW ongase ufune ukukwazi

I-UHMW-PE imele i-Ultra High Molecular Weight Polyethylene.Iyikhwalithi ephezulu kakhulu ye-polyethylene (PE) etholakalayo, eyakhelwe imisebenzi enzima kanye nohlu olubanzi lwezinhlelo zokusebenza.

Iletha ukonga kwizicelo eziningi ezinzima.I-Ultra High Molecular Weight iyimfihlo yale mpahla eyingqayizivele yale polymer.I-polyethylene resin yayo ephezulu kakhulu inesisindo samangqamuzana ezigidi ezingu-3 kuya kwezingu-6, uma kuqhathaniswa nezingu-300,000 kuya kwezingu-500,000 ze-high molecular weight (HMW) resins.Lowo mehluko yiwo oqinisekisa ukuthi le nto inamandla ngokwanele ukumelana nokuhuzuka nokuba nomthelela kangcono kunemikhiqizo ye-poly esezingeni eliphansi.Isisindo samangqamuzana esiphezulu se-UHMW-PE sisho ukuthi ngeke sincibilike noma sigeleze njengoketshezi oluncibilikisiwe.Ngakho-ke izindlela zokucubungula zithathwe kulezo zobuchwepheshe bensimbi eyimpushana.I-UHMW-PE ayikwazi ukuguqulwa futhi ibunjwe ngamasu ajwayelekile okucubungula ipulasitiki (ukubumba umjovo, ukubunjwa kokushaywa noma ukwenza i-thermoforming).Ukubumba kokuminyanisa kuyinqubo evamile yokuguqula esetshenziswa nale resin ngoba ikhiqiza umkhiqizo onamandla, ongaguquki.

I-UHMW yaziwa ngokumelana kwayo nokuhuzuka okuphezulu, ukugcotshwa kwemvelo, amandla omthelela aphezulu, amakhemikhali-, ukugqwala, nokumelana nomswakama kanye ne-acoustic impedance.

Ngenxa yezakhiwo zayo ezikwazi ukumelana nokuhuzuka, ukugqwala, amakhemikhali kanye nomswakama, i-UHMW ivamise ukusetshenziswa ezinhlelweni lapho izimo zingase zibe nzima kakhulu kwezinye izinto.I-polymer yokusebenza ephezulu engabizi kakhulu esetshenziselwa ukukhiqiza izingxenye eziphansi, ezisezingeni eliphezulu.

I-UHMW iyimpahla ezigcoba ngokwayo ebonisa ukuguga nokuhuzuka okuhle kakhulu futhi yengeza amandla omthelela aphezulu kakhulu.Izimakethe ezimbalwa ezizosebenzisa lezi zimfanelo kungaba ama-snowboard bottoms, ukuphatha amaphakheji, ukupakisha, ukucubungula ukudla kanye nezimoto.

Isisindo samangqamuzana aphezulu yiso esinikeza i-UHMW-PE inhlanganisela eyingqayizivele yamandla omthelela aphezulu asebenza kahle wokungqubuzana nokumelana nokuhuzuka okwedlula i-carbon steel 10 kuya ku-1 okwenza ifaneleke kakhulu izinhlelo zokusebenza lapho amamaki esisindo sengqamuzana ehlulekayo.

Kukhona izivivinyo ezintathu ongazenza:

1. Shisa Ukuhlolwa - khanyisa ngomentshisi futhi uhogele intuthu.Uma iphunga njenge-wax yekhandlela - lokho kubonisa i-polyethylene.I-UHMW ayiconsi kalula njenge-HDPE kodwa izoconsa.
2. Ukuhlolwa kwe-oven - kubeke endishini ye-aluminium kuhhavini ongu-300 degree.I-HDPE evamile izowohloka noma inyibilike kodwa i-UHMW ngeke ishintshe usayizi noma umumo.Kodwa-ke, ingasonteka noma ihlanekezelwe ngenxa yengcindezi eyakhelwe ngaphakathi.

I-Saw Test - Uma isikwa ngesaha, i-HDPE evamile inikeza amasaha noma amafayili kuyilapho i-UHMW inikeza izintambo noma lutho.
