UHMW-pe Polyethylene ndeimwe yemapurasitiki makuru uye anonyanya kushandiswa purasitiki, accounting kweanenge 30% yehuwandu hwepasi rese plastic. Pakati pavo, ldc, hdpe naLlpe, iyo yechitatu chizvarwa chePolyethlene. zvivakwa.
Sekureva kweiyo nzira yekufananidza yePhillips petroleum kambani, iyo polyethyle ine molecular uremu kupfuura 1.5 miriyoni inodaidzwa kuti "uhmwpe" (Ultra-yakakwira molecular uremu pe). Germany Hoochst (Hochst) Kambani, United States Hercules (Hercules) Makambani matatu epasi repamusoro anogadzira Uhmwpe, China Huve mugadziri
Iyo yakakwira molecular uremu hweUHMWPE (uremu hweHDPE kazhinji chete 2 ~ Izvo zvine zvakanakira marudzi ese emapurasitiki, uye zvine zvakanakira kupfeka-kuramba, zvinokanganisa, kuramba, kuramba, kuramba, kupamba, kupokana uye zvisiri zvehupfu uye zvisina chepfu, kwete -Ashesive, mvura-inobata, density-inonakidza, uye zvichingodaro, iyo isingadzivisiki mune yakajairika polyethyle uye mamwe mainjiniya mapurasitiki. Kunamatira, kwete nyore kutora mvura, kushoma density uye kumwe kuita kwakazara. Muchokwadi, hapana imwe chete polymer zvinyorwa zvine huwandu hwakawanda hwakanakisa hwezvivakwa.
1. Abraesion Kudzivisa
Iyo Abrasion kupokana neUshwpe ndiyo yepamusoro pakati peplastics, uye inodarika iyo yemamwe mitezo. Kuenzaniswa neyimwe yeinjiniya mapurasitiki, UHMWPE's jecha Slurry Abrasion Index Ingori 1/5 ye Pa66, Hepe And PVC 1/10; zvichienzaniswa nesimbi, iri 1/7 yeCarbon Simbi, brass l / 22o yakakwirira kushandisazve plastics tablassion table test nzira yekuedza kupokana, uye saka kunyatsogadzira jecha slurry abrasion test kifaa. Uhmwpe abralion kupokana uye molecular uremu hwakananga zvakananga kune iyo molecular uremu, yakakwira huremu hwemanyorerwe, zvirinani kupokana kwayo.
Iko kukanganisika simba reUHMWPE ndeimwe yepamusoro pakati pevese mainjiniya mapurasitiki, ayo anenge ka2 kakawanda sePC, kakawanda kupfuura gumi, uye kanopfuura ka9 kakawanda seye p0m uye pbtp. Simba rekuchinja kweUhmwpe inenge 2 times iyo yePC, ka5 iyo yeABS, uye kanopfuura kagumi iyo yeP0M uye PBTP. Simba rekukanganisa rakakwira zvekuti zvakaoma kupwanya uhmwpe neyakajairwa nzira yekuedza. Simba rayo rekukanganisa rinovandudzika nekuwedzera kwemanyorose uremu uye kusvitsa huwandu hwepamusoro kana iyo molecular uremu hwemamirioni 1.5, uyezve zvishoma nezvishoma inoderera nekuwedzera kwehuremu hwemanyorerwe. Izvo zvakakosha kucherechedza kuti inochengetedza simba rakanakisa simba mumvura nitrogen (-195c), hunhu husingawanikwe mune dzimwe plastics. Mukuwedzera, zvakaoma pane kudzokorora kukanganisa.
Uhmwpe ine yakanyanya kuderera friction factor (~), saka kuzviisa pachako kwakanaka. Uhmwpe mhombwe yemvura mumamiriro emvura iri pa66 uye pom 1/2, mune isina-lubrication mamiriro, yechipiri kune yekuzvimiririra kweiyo yepamusoro 1 polytetrafluorohlene (PTFF); Kana ichinge iri muchimiro chekutsvedza kana basa renzvimbo, pane kuiswa kwesimbi uye yerwendo mafuta ekuremerwa mafuta ari nani zvakanyanya. Naizvozvo, mumunda weMuti dzeMuti, Uhmwpe unoonekwa seyakanakisa yekukakavara zvinyorwa maererano nemitengo / kuita.
Uhmwpe ine yakanaka yemakemikari kurwisa, kunze kweiyo yakasimba oxidizizization acid, inogona kuramba marudzi ese ezvipenyu (asidhi, alkali, kunze kweiyo solvent) mukati meimwe tsvina tembiricha uye yekushambadzira. Izvo zvinokanganiswa mumhando makumi masere emhando dze organic soles na20 ° C ne 80 ° C kwe30d, hapana chinhu chisina kujairika pane chitarisiko, uye zvimwe zvinhu zvemuviri zvinenge zvisina kuchinjika.
5, kukanganisa simba kwesimba
Uhmwpe ine yakanakira kukanganisa simba, kukanganisa kwesimba kukosha kwekutora ndiko kwakanyanya pakati pevolasti dzepurasitiki, saka kurira kwemheremhere kwakanaka kwazvo, nekudzikisira kwakanaka kwazvo.
6, kudzikisira kupisa
Uhmwpe ine yakanyanya kuderera-tembiricha yekushisa, mune yemvura nitrogen tembiricha (-269 tembiricha (-269 ° C) ichine ductility, uye saka inogona kushandiswa kune iyo nyukireya indasitire-tembiricha.
7, hutsinye husiri hwehupfu
Uhmwpe hutsanana nacho, mukuteedzera zvizere nehuwandu hweJapan Hutano hweVaJapan, uye kuzivikanwa kweU.Sangano rekurima uye neDhipatimendi reUS rekurima, rinogona kushandiswa kuonana kwechikafu.
8, isiri-inonamira
Uhmwpe pamusoro uye kugona kweAdsorption kune isina kusimba, tho anti-adsion kugona ndeyechipiri chete kune iyo yepurasitiki mune yakanakisa 1 ptfe, saka pamusoro pechigadzirwa uye zvimwe zvinhu hazvisi nyore kuomerera.
9, kudhara kudiki kwemvura
Uhmwpe mvura yekunyora inoderera
10, density
Iyo density yeUhmwpe yakaderera pane ese mainjiniya mapurasitiki, kazhinji akaderera pane ptfe 56 mukaka pane pbm 33% yakaderera kupfuura pbtp 30%, saka zvigadzirwa zvaro zvirema zvakanyanya.
11, Simba Resimba
Nekuti uhmwpe ine maitiro anodiwa eiyo tensile kutarisisa, saka inogona kushandiswa kugadzira Ulasticity uye Simba reSpinning neGel Spinning nzira, uye Simba rayo rakafanana rakakwira se3 ~ 3 ~, uye modugulus ye elasticity yakakwira se 100 ~ 125gpa. Simba rakananga reiyo fiber ndiyo yepamusoro mafambiro kusvika pari zvino kusvika parizvino, iyo ina yakakura kupfuura iyo yeCarbon Wires, uye 50% yakakura kupfuura iyo yerudzi rwemarwi. Iyo in 4 times yakakura kupfuura kabhoni fiber, kagumi yakakura kupfuura waya yesimbi, uye 50% yakakura kupfuura aramid fiber.
12, zvimwe zvivakwa
Uhmwpe ine zvakare magetsi akanakisa ekusimbisa kwemamiriro ekunze
Zvikumbiro zveUhmwpe
Parizvino, uhmwpe yakave ichishandiswa zvakanyanya muminda yezvidimbu, mapepa, zvekutakura, zvindori, zvokunyika, zvemagetsi, zvokudya, zvemitambo, nezvimwe, nezvimwe, nezvimwewo, zvatanga kupinda munda Zvombo zvakajairika, ngarava, mota, etc. mune ramangwana, zvichawedzerawo simba uye simba reatomi. Mune ramangwana, ichave yakawedzerwa kuminda yeaErospace uye atomius simba.
1, pfeka kuramba uye kukanganisa zvinyoreso
Machira emachira
Machina ekunyorwa kwekutanga kwekushandisa kweUhmwpe mumunda, kutanga kwa1958, kune makambani akati wandei ekudzivirira kugadzirwa kwezvikamu zvemukati, sekutsiva kuomarara kwezvinhu zvinogadzirwa neBuffalo ganda ganda remapanga emapanga pane Chidhokungoisa kukanganiswa kwekukanganisa kwenguva refu kwe40 ~ 180 times / min, hupenyu hwekusvika kune buffalo ganda kno 5 ~ 6 times. Parizvino, zvekunze zvinoshandiswa mune imwe neimwe loompe zvikamu paavhareji angangoita makumi matatu, akadai sedheni yekukanda, mabhebhi, mabhebhi, anodzora bushings, achitsvedza danda uye kumwe kukanganisa kupfeka zvikamu.
Pepa kugadzira michina
Machina emapepa ndiko kushandiswa kweUhmwpe munda wechipiri weindasitiri, munenge muna 1960, mune yehuni Conveype akapfeka mitsetse, iyo Conney Plate uye cheni yekuita basa rakanaka mukuchengetedza kushandiswa kwe5a hapana pfeka. Zvinofungidzirwa kuti hupenyu hweanosimudzira-mhirizhonga mitsetse inopfuura kaviri kana hupenyu hwomanje. Uhmwpe uye zvimwe zvinopfekedzwa-zvinopesana zvigadzirwa simbi Akaderera kupfuura iwo emamwe midziyo, ayo anopinda hupenyu hwesimbi inodhura isina kufa mesh. Nhasi, iyo yepepa Indasitiri Inoda Uhmwpe Kushandiswa kwe10% yehuwandu hweUhmwpe Kugadzira mapepa mashini ane chisimbiso shaft, deflector, scrlector, firita uye zvimwe zvikamu.
Kurongedza michina
Iyo yakakwira kupfeka kurwisa, kusanzwisisika kwekunyepedzera kweUhmwpe kunoita kuti ive yakakodzera kupfuura mamwe masimbi uye mamwe mapurasitiki emishini, uye inogona kutsiva phosphor bronze uye fluorine plastiki. Uchishandisa uhmwpe yekutsiva yakagadziridzwa fluoroplassics yekugadzira nhunzi njanji, solider yakasimba midziyo yekudyara, etc. Iyo Liquid DECKTERT FECUTE CHINANGWA CHINANGWA CHEMA CHEMA CHEMA CHEMA CHEMA CHEMA CHEMA CHEMA Zvikamu zveSpare, uhmwpe akagadzira nguva screws, zvakare yakashandiswa seyakajairwa chikamu mumutsara wakawanda. Iyo hombe doro fekitori kumadokero, ne uhmwpe yakaburitsa chibvumirano cheBelt Belt Belt Belt Belt Belt, pane kushandiswa kwe phosphor Bronze yakagadzirwa neBelt Belt Durability yenguva dzinoverengeka. Musangano wemotokari chirango Iko kushandiswa kweiyo Uhmwpe pepa rekutsiva ndiro yesimbi zvikuru inoderedza kupfeka uye kubvarura, uye zvakare kuderedza simba rekushandisa simba.
General chinangwa michina
Sezvo Ushmpe ine yakanakisa kupfeka uye kukanganisa kupokana, zvinogoneka muindasitiri yekugadzira michina, uye inogona kuitisa marudzi ese emagiya, maLellers, fani, bushings, shaft cutters, gasi , kuisimbisa maskiti, elastic couplings, zviyero uye zvimwe zvikamu zvekushandisa.
