Yintoni i-Ultra-High Molecular-Weight Polyethylene (UHMWPE)

I-Polyethylene yeyona plastiki isetyenziswa kakhulu kwihlabathi, kodwa wazi njani ukuba ngumsonto ofanelekileyo kwisicelo sakho?Cinga ngeempawu ze-ultra-high-molecular-weight-weight polyethylene (UHMWPE) - i-subset enzima kakhulu ye-polyethylene enamandla kumlinganiselo we-8-15 amaxesha amakhulu kunentsimbi.

Eyaziwa kakhulu ngamagama orhwebo eSpectra® kunye neDyneema®, iiplastiki ze-UHMWPE kunye nemisonto zisetyenziselwa ikakhulu:

· Ukusetyenziswa kweBallistic (Isikrweqe soMzimba, ukuPlatyiswa kweSikrweqe)

· Imidlalo kunye nolonwabo (ukuntywila esibhakabhakeni, ukutyibiliza, ukutyibilika, ukuloba)

· Iintambo kunye neentambo

· Ukuphathwa kwezinto ezininzi

· Amalungu aneebhobhosi kunye nesihluzo

· Ushishino lweemoto

· Ishishini lemichiza

· Ukulungiswa kokutya kunye noomatshini bokusela

· Izixhobo zokwenziwa kwemigodi nezimbiwa

· Izixhobo zokuvelisa

· Ubunjineli bokwakha kunye nezixhobo zokushukuma komhlaba

· Usetyenziso olunxulumene nezothutho, kubandakanywa iitreyi zelori, imigqomo neehopper.

Njengoko unokubona i-UHMWPE inoluhlu olwahlukeneyo lokusetyenziswa ukusuka kwimveliso ukuya kwezonyango kunye nocingo kunye nosetyenziso lwentambo.Oku kungenxa yoluhlu olude lwezibonelelo ezihlangabezana neemfuno ezithile zemisebenzi emininzi eyahlukeneyo.

Uncedo lwe-UHMWPE lubandakanya, kodwa aluphelelanga koku:

· Ukumelana okugqwesileyo kuxinzelelo kunye nokumelana okuphezulu nokuqhekeka

· Ukuxhatshazwa kwe-abrasion yokunxiba - amaxesha angama-15 axhathisa ngakumbi kwi-abrasion kune-carbon steel

· Inamandla ngama-40% kunemisonto ye-Aramid

· Ukumelana kwayo neekhemikhali olomeleleyo-yomelela kakhulu kwii-alkalis ezininzi kunye ne-asidi, izinyibilikisi zendalo, ii-agent zokuthoba kunye nohlaselo lwe-electrolytic.

· Ayinatyhefu

· Iipropati ezibalaseleyo zedielectric

· Ukuzithambisa – umlinganiso ophantsi kakhulu wokukhuhlana (uthelekiseka ne-PTFE)

· Ayinabala

· I-FDA ivunyiwe ukuba isetyenziswe ekutyeni nakwizicelo zonyango

· Umxhuzulane othile osezantsi – uya kudada emanzini

Ngelixa oku kunokuvakala ngathi yinto efanelekileyo, kukwakho nezinye izinto ezingeloncedo ezimbalwa omele uzazi.I-UHMWPE inendawo esezantsi yokunyibilika (297° ukuya kuma-305° F) kuneepholima ezininzi eziqhelekileyo, ngoko ke ayifanelekanga ukusetyenziswa kobushushu obuphezulu.Ikwanayo ne-coefficient ephantsi ye-friction enokuthi ibe yi-drawback ngokuxhomekeke kwisicelo.Imisonto ye-UHMWPE inokuphuhlisa “ukurhubuluza” phantsi komthwalo ongaguqukiyo, nto leyo yinkqubo yokolulwa ngokuthe ngcembe kwemisonto.Abanye abantu banokuthatha ixabiso njengento engalunganga, nangona kunjalo xa kuziwa kwi-UHMWPE, ngaphantsi kungaphezulu.Ngenxa yokomelela kwesi sixhobo akufuneki uthenge kakhulu njengoko ubuya kwenza ngezinye izinto.
