Sinesipiliyoni seminyaka engaphezu kwengu-20 kupulasitiki wobunjiniyela, ikakhulukazi kupulasitiki we-PE. Singamalungu ebhodi le-SRICI kanye ne-CPPIA. Sihlanganyela futhi sidweba imithetho ejwayelekile yenqubo yepulasitiki.
Singenza okuhlukileIshidi le-UHMWPEngokwezinhlelo zokusebenza ezahlukene. Njenge-anti-static engamelana ne-UV kanye nezinye izinhlamvu, ikhwalithi engcono kakhulu enobuso obuhle nombala yenza ishidi lethu le-UHMWPE lithandwe kakhulu emhlabeni wonke.
1.Ishidi le-Uhmwpebanokumelana okunamandla okuhlala kune-polymer ye-thermoelectricity.
2. Ishidi le-Uhmwpe linokumelana okuhle kakhulu nokushaqeka ngisho noma izinga lokushisa liphansi.
3. Ishidi le-Uhmwpe linesici sokungqubuzana esiphansi, kanye nezinto zokuthwala ezishelelayo.
4.Ishidi le-Uhmwpezinokunambitheka okumnandi (azinawo amakhekhe, zinamathela).
5. Ishidi le-Uhmwpe linokumelana okuhle kakhulu nokugqwala kwamakhemikhali kanye nokumelana nokucindezeleka.

Uma ufuna izinto ezithembekile nezihlala isikhathi eside zezinhlelo zokusebenza ezifaka ukuguguleka okukhulu kanye nomthelela, ungabheki kude kuneshidi le-UHMWPE. I-UHMWPE imele i-Ultra High Molecular Weight Polyethylene futhi iyishidi lepulasitiki elinikeza ukusebenza okuhle kakhulu ezimweni ezimbi kakhulu. Ngenhlanganisela yalo eyingqayizivele yezakhiwo, le nto ithola ukuthandwa ezimbonini ezahlukahlukene.
Esinye sezimpawu eziyinhloko zeshidi le-UHMWPE ukuguguleka kwalo okuphezulu kanye nokumelana nokushayisana. Kungakhathaliseki ukuthi ukuguguleka okuqhubekayo noma ukuguguleka kokungqubuzana okubangelwa izingxenye zensimbi, le nto ingakwazi ukumelana nayo. Kusukela kuma-chute kanye nama-hopper linings kuya kuma-conveyor noma izingxenye, ama-wear pad, ama-machine rails, izindawo zokushayisana kanye nama-rail, amashidi e-UHMWPE ayisinqumo sokuqala.
Kodwa akupheleli lapho! Ishidi le-UHMWPE linezinye izinzuzo eziningi ezenza libe yinto esezingeni eliphezulu yezinhlelo zokusebenza zobunjiniyela. Okokuqala, alimelani ne-UV, okusho ukuthi lingamelana nokuchayeka elangeni isikhathi eside ngaphandle kokuwohloka. Lokhu kuyenza ifaneleke ukusetshenziswa ngaphandle, okuqinisekisa ukuthi ihlala isikhathi eside futhi inokwethenjelwa kuzo zonke izimo zezulu.
Esinye isici esiphawulekayo se-Ishidi le-UHMWPEiwukusebenza kwayo okuhle kakhulu. I-coefficient yayo ephansi yokungqubuzana kanye nokulula kokucutshungulwa kwenza kube yinto eguquguqukayo ngezinjongo zobunjiniyela. Kungakhathaliseki ukuthi ukusika, ukubhoboza noma ukwakha, amashidi e-UHMWPE angacutshungulwa kalula ukuze ahlangabezane nezidingo ezithile, okusindisa isikhathi nomzamo.
Ngaphezu kwalokho, amashidi e-UHMWPE cishe awakwazi ukuhlaselwa ngamakhemikhali. Amelana kakhulu namakhemikhali ahlukahlukene, ama-asidi kanye nezisekelo, okuqinisekisa ubuqotho bawo ngisho nasezindaweni ezinzima. Lokhu kuwenza ube yindawo ekahle yokusetshenziswa ehilela ukuchayeka ezintweni ezibolayo.
Ngaphezu kokumelana namakhemikhali,Ishidi le-UHMWPEAma-s nawo awavimbi futhi awanamatheli. Lokhu kusho ukuthi izinto kanye nemfucumfucu cishe akunakwenzeka ukuthi zinamathele noma zinamathele ebusweni bayo, okuholela ekusebenzeni kahle kanye nokunciphisa izidingo zokunakekelwa. Kungakhathaliseki ukuthi okusanhlamvu, amalahle noma ezinye izinto, amashidi e-UHMWPE aqinisekisa ukugeleza okuhle kakhulu futhi avimbele ukuvaleka.
Ngaphezu kwalokho, ishidi le-UHMWPE liphinde libe nezakhiwo zikagesi ezinhle kakhulu. Linamandla aphezulu e-dielectric, okwenza libe yi-insulator efanelekile ekusetshenzisweni kukagesi nokwe-elekthronikhi. Ukumuncwa kwalo umswakama ophansi kanye nezakhiwo ezinhle zokuvimbela ugesi kwenza kube ukukhetha okuthembekile ezindaweni ezahlukahlukene eziyinselele.
Enye inzuzo yeshidi le-UHMWPE yikhono lalo lokusebenza kahle emazingeni okushisa apholile. Ngokungafani nezinye izinto eziba buthaka emazingeni okushisa aphezulu, ishidi le-UHMWPE lihlala liqinile futhi liguquguqukayo ngisho nasemazingeni okushisa angaphansi kwezinga-zero. Lokhu kuyenza ifaneleke ukusetshenziswa okudinga ukusebenza okuphezulu ezindaweni ezibandayo.
Ngokuphathelene nokumelana nokushisa,Ishidi le-UHMWPEinezinga lokushisa eliphezulu lokusebenza elingu-80°F. Lokhu kusho ukuthi ingamelana namazinga okushisa aphezulu ngaphandle kokuguquka okubonakalayo nomaukuwohloka. Kodwa-ke, izidingo ezithile zokusetshenziswa kanye nemikhawulo yokushisa kumele kucatshangelwe ukuqinisekisa ukusebenza kahle kakhulu.
Okokugcina, ukumuncwa kwamanzi kweshidi le-UHMWPE kuphansi kakhulu, kungaphansi kuka-0.01%. Lesi sici siyenza imelane nomswakama, ngisho nasezindaweni ezinomswakama, futhi sinciphisa ingozi yokuvuvukala noma izinguquko zobukhulu. Lokhu kuphinde kusize ekusebenzeni kwayo isikhathi eside kanye nokuqina.
Ipuleti lepulasitiki le-UHMWPE lisetshenziswa lapho kwenzeka khona ukuhuzuka okushelelayo noma lapho izingxenye zensimbi zihlangana khona, okubangela ukungqubuzana noma ukuguguleka kokuhuzuka. Lihle kakhulu kuma-chute kanye nama-hopper liner, ama-conveyor noma izingxenye, ama-wear pad, ama-machine guides, indawo yokushayisana kanye ne-guider rails.
Ekuphetheni,Ishidi le-UHMWPEiyisisombululo esiphezulu sezinhlelo zokusebenza ezidinga ukuguguleka okuphezulu kanye nokumelana nokushayisana. Njengoba inezakhiwo eziningi ezifiselekayo njengokumelana ne-UV, ukucutshungulwa kalula, ukungangeni kwamakhemikhali, ukungqubuzana okuphansi, ukungagugi, izakhiwo zikagesi ezinhle, ukumelana nokubanda, kanye nokumuncwa kwamanzi okuncane, isibe yinto ethandwayo ezimbonini ezahlukahlukene. Ngakho-ke, kungakhathaliseki ukuthi ufuna ukumelana nokuguguleka okuphezulu noma izingxenye ezithembekile ezenziwe ngobunjiniyela, ishidi le-UHMWPE liyimpendulo yakho!
