Basic Pfuma ye Ultra-Yakakwira Molecular uremu Polyethylene (UHMWPE)

ULTRA Density yeUhmwpe ine avhareji yehukama misai ye200 10 iyo yeparakemaldehyde, saka zvigadzirwa zvaro zvinoonekwa nehuremu hwakajeka. Uhmwpe ine akasiyana-siyana emhando yezvivakwa, zvivakwa zvemakemikari, zvinopfekedza, zvinokatyamadza, zvinokatyamadza, mvura yakaderera, isiri nyore kuomerera kune zvinhu zvekunze, hutsanana uye Asiri-utsi, kudzokorora uye kudzikisira kudziya kupesana, nezvimwe, kunyanya, kupokana kwayo kwabazwi kwakanyanya. Zvikanganiso zvavo zvakashata zvinopisa kupisa, kuoma kwakaderera, kusimba kwakadzika simba, murazvo wakashata murazvo unodzora zvivakwa.

1. Performance data yeUhmwpe

2. Mechanics Properties

(1) Kuipa Kunodzivisa

Simba rekukanganisa reUhmwpe riri pakati pezvakanakisa muzvikamu zvese zveinjiniya. Uhmwpe inogona kuchengetedza kukonzeresa kuramba kunyange pakudziya kwakadzika, uye kunyange mumvura nitrogen (-196 ℃), uhmwpe ine simba rakapusa, iro hunhu hune hunhu hwakaitwa nevamwe mapurasitiki. Simba rayo rekuimba rinotanga kuwedzera nekuwedzera kwerudzi rwemanyorerwo, iyo hama yemasuru zana nemakumi mashanu nemashanu kana kuti tisvike huwandu hwayo hwekusimuka uye zvishoma nezvishoma kuderera. Iko kukanganisika simba reUHMWPE inenge 2 times seyakafanana nePolycarbonate, ABS kashanu, pa, parformacadehde uye pbt kanopfuura kagumi.

(2) anodzivisa kubata

Iyo Abrasion Rishance yeUshmwpe inovhara runyorwa rweplastics, kakawanda yakakwira kupfuura iyo yeCarbon Simbi uye yendarira, uye kuparadzaniswa kwayo kwakawanda kunogona kuitika nekuwedzera kweiyo hama yemanyorero. Mufananidzo 1-1 unoratidza kuenzanisa kwekupfeka kurwisa pakati peUhmwpe uye zvimwe zvinhu. Mamiriro ezvinhu ekuedzwa ari seinotevera: Iyo mongwe inoumbwa ne2 mizhinji zvikamu zvemvura uye zvikamu zvitatu zvejecha; kumhanya kwekutenderera kweyekupedzisira chidimbu ndeye 900r / min; Iyo nguva yekumhanya ndeye 7H.

Kuenzanisa kweabrasion kuramba kwe uhmwpe nezvimwe zvinhu

(3) kuzvisimbisa

Uhmwpe ine yakanaka yekuzvinyudza uye yakaderera dutu remhepo criction contor yakafanana neiyo yePTFE. Tafura 1-0 Zvinogona kuoneka kuti kinetic yekukakavara kweUhmwpe Kana ichishanda mukutsvedza kana kutenderera fomu, ine chekuita zvishoma nezvishoma pane simbi uye ndarira nekuwedzera kwemafuta anovharira. Uyezve, mutengo weUhmwpe wakaderera, saka mumunda weMitatu, zvinoonekwa sechinhu chezvinyorwa zvine mutengo wakanaka kwazvo-performance.

Kuenzanisa kweDynamic Friction Factor mamiriro eUHMWPE uye mamwe mainjiniya mapurasitiki

(4) Simba reSimba

Simba rakabiwa rakabikwa reUhmwpe rine hukama hwehukama hwehukama uye llensity, nekuwedzera kwehama uye kusimba kwesimba kuderera, simba rakabiwa rakabiwawo kuderera kunoderera zvakare; Nekudaro, apo density iri 0.94g / cm3 kana cm3 kana hama yemanyorero inopfuura 150 × 104, shanduko yeiyo yakajeka inopa simba simba idiki, uye zvinowanzoita kukosha kwakasimba. Simba rekutyora rekutyora rinongoenderana neyemukuru wemolecular misa, uye mhedzisiro yekuwedzera pane izvo zvine usingakanganwiki. Kupesana neine simba rakabiwa simba, nekuwedzera kwehama mumuromo, simba rekuputsa rakawanda rinowedzera.

3. Zvivakwa zvemagetsi

Zvakafanana neyakajairika polyethyle, iyo molecular keteni yakaumbwa kabhoni uye hydrogen yeiyo uhmwpe yakazvimirira yehukuru hwemanyorero misa, saka ine zvivakwa zvakanaka zvemagetsi zvemagetsi. Yayo puroksvesa yakakwira se 1016 ~ 1018ωω-cm, uye iyo dielectric kurasikirwa kona tangenent ndeye (2 ~ 3) × 10-4. 4.

4. Inopisa Zvivakwa

Iyo yekupisa kudzikisira yeUhmwpe haina kukwirira, iyo tembiricha yekushandisa kazhinji iri pazasi 100 ℃. Nekudaro, nekuda kwehukama hwayo hukuru hwakakura kwazvo, saka kupisa kwekushisa tembiricha uye vicat kupfava kwekunyorova kwakakwira kupfuura izvo zveHDPE, 13 Nekudaro, uhmwpe ine yakanaka kwazvo tembiricha yekushisa, iyo yakanakisa pakati pemalastics ese, tembiricha yekudziya iri pazasi -0, kunyangwe iyo yemvura helium tembiricha (-3 ℃) iri pazasi -70, uye tembiricha yemvura helium tembiricha (-4 ℃) iri pazasi -70 ℃, uye tembiricha yemvura yemvura helium tembiricha iri pazasi -70 ℃. Tembiricha yeBrittle inosimuka iri pazasi -70 ° C, uye kunyange pamvura helium tembiricha (-269 tembiricha (-269 ° C) ichine zvimwe zvinokanganisa simba uye kusimbisa usimbe. Kunyangwe pakudya kwemvura helium tembiricha (-269 ℃), ichine zvimwe zvine simba simba uye abrazion kuramba. Iyo yekushanda tembiricha yakabva ku -265 kusvika ku100 ℃, uye inogona kuramba ichikanda kuomarara kwakanaka uye simba pasina kudzika kana tembiricha yakaderera se -195 mamiriro akadai seindasitiri yenyukireya.

5. Kemical Resistance

Uhmwpe ine yakanaka yemakemikari kuramba. Diethane, etheryne Glycol, peturu, Heptane, Hexcelexane, Hospuls, Methyels One Solvent Solarns yechionekwa chisina kana chinoshungurudza chiitiko, kuita kwemarudzi akasiyana siyana asina shanduko. Izvi zvinokonzerwa nenyaya yekuti Ultra-yakakwira molecular uremu polyethyle isina boka remanyorerwo, uye hapana chisungo chekamhepo uye chisungo chechipiri pamwe nekukwira kwakanyanya. Nekudaro, haina kugadzikana mukunyudzwa kweiyo sulfutic acid, yakadzvanywa hydrochloric acid, yakagadzirirwa nitric acid, hyrated hydrocarbons uye zvimwe zvinonyadzisira, uye mishonga yemhando yekuwedzera inowedzera nedzimwe tembiricha.

6. mvura yekunyura

Iyo mvura yekunyora yeUhmwpe ndiyo diki pakati peinjiniya mapurasitiki (isafinhi 1-3), iyo inokonzerwa neicho cheni yeUhmwpe ine kabhoni uye hydrogen zvinhu chete, uye hapana boka rePolar mumorekuru, Saka iwo mwero wekunyora mvura zvakanyanyisa kuderera. Naizvozvo, zvigadzirwa hazvizoshanduke muhukuru nekuda kwemvura kunyangwe munzvimbo ine mwero, uye panguva imwe chete, zvakadai sekunyorwa uye zvinopesana nekurovera, uye zvinhu zvisina kufanira hazvidi kuomeswa usati waumbwa uye kugadzirisa.

Mvura inobata yeiyo dzinowanzoitika engineering mapurasitiki

7. Ultra-yakakwira molecular uremu polyethylene application

Nekuita kwakanakisa kwekuita, uhmwpe yakashandiswa zvakanyanya muminda yemachina, midziyo yemagetsi, zvekutakura, kuendesa mapepa, etc. Zvigadzirwa zvikuru ndezvekuti: Sheets, pombi, tsvimbo uye zvakapedza zvigadzirwa. Zvigadzirwa zvikuru ndezvekuti: Mahwendefa, ma pombi, matanda uye anosanganisira zvigadzirwa, fani, bushings, anofamba-bhururuka, anotungamira njanji, zviyero, zvifananidzo uye zvichingodaro. Kubva pane tekinoroji yezvigadzirwa zvacho zvinokonzerwa nekuumbwa, machinji, kuumbwa, kuputika, kuputika, kurira kuumba, iyo thermoplastic yekuumba kuumbwa uye waya kudhirowa kuumbwa.
