1. Roller yeUHMWPE data
Polyethylene ine huremu hwemamorekuru hunodarika miriyoni 1.5 inonzi "UHMW-PE", iyo inoshandiswa sepurasitiki yeinjiniya nekuda kwekuita kwayo kwemuviri kwakanaka.Kana isu tichisarudza zvigadzirwa, isu tinotanga tafunga anotevera akanakisa ekushandisa mabasa:
(1) Pfeka kuramba Kupokana kweUHMWPE kunotanga pakati pemapurasitiki uye kunodarika mamwe masimbi.Kwakadaro kupfeka kwakanyanya kuramba kunoita kuti zviome kuyedza kupfeka kwayo neyakajairwa epurasitiki kupfeka nzira dzekuyedza.Nokudaro, kupfeka kwedhaka kunosarudzwa.Mumidziyo yekuyedza, kupfeka kuramba kunoenderana nehuremu hwemamorekuru, sezvo huremu hwemamorekuru huchiwedzera, kupfeka kuramba kunenge kuri nani;
(2) Impact kuramba uye kukanganisa simba kutorwa.Zvakaoma kutyora uye kukuvadza neyakajairwa maitiro ekuyedza nzira.Simba rayo rekuita rinowedzera nekuwedzera kwehuremu hwemamorekuru, kusvika pakakwirira apo huremu hwemamorekuru huri 1.5 miriyoni, uyezve inoenderera ichiwedzera nehuremu hwemamorekuru.Uye zvishoma nezvishoma kuderera.Mukuwedzera, ine yakakwirira yepamusoro kuoma mushure mekudzokorora kukanganiswa;ine yakanakisa kukanganisa simba kunyudza, iyo ine yakanyanya kunaka simba kunyudza kukosha pakati pemhando dzese dzepurasitiki, saka ine yakanaka inoderedza ruzha uye yakanakisa kuderedza ruzha;
(3) UHMWPE inozvigadzika ine kakato kadiki kwazvo (0.05～0.11), saka yakanakisa mukuzvizora.Kubva paTafura 1, zvinogona kuonekwa kuti kupesana kwechinhu chakaderera kune yakanakisa self-lubricating polytetrafluoroethylene (PTEE), saka inorumbidzwa mumunda wekurwisana nesayenzi sechinhu chine mabasa akanaka emari;
(4) Chemical resistance.Iyo ine yakanakisa makemikari kuramba.Kuwedzera kune yakasimba oxidizing acids, inogona kumira zvakasiyana-siyana zvinoparadza midhiya (senge acids, alkalis, uye munyu) uye organic media pane imwe tembiricha nekudzika.Mushonga wetii uri kunze).Inonyudzwa mumhando makumi masere ezvinyungurutsi zve organic pa 20°C uye 80°C kwemazuva makumi matatu pasina chitarisiko chisina kujairika, uye mamwe mabasa emuviri anenge asina kushanduka;
(5) Non-stick UHMWPE ine simba rakanyanya kusimba pamusoro pekushambadza, uye kugona kwayo kwekudzivirira kunamatira ndeyechipiri kune PTEE, iyo inonyanya kunamatira mupurasitiki, saka kutaridzika kwechigadzirwa hakusi nyore kunamatira kune zvimwe. zvinhu.Mukuwedzera, UHMWPE inewo maitiro ekudzivirira kutsika kwepasi (kuita kuti roller ishande kune yakakura), hutsanana, husina chepfu, uye hydrophobic (iyo roller haisi nyore kutora mvura uye kuremara).
Izvo zvinokanganisa zveUHMWPE: Zvichienzaniswa nesimbi uye mamwe mapurasitiki einjiniya, kupisa kupisa, uye kuoma kwakaderera, asi zvinogona kuvandudzwa ne "kuzadza" uye "crosslinking".
2. Kukwirira kwe-ultra-high molecular weight polyethyleneconveyor idler roller
(1) Nekuti iyo inoshanda yekudzivirira coefficient uye rolling inertia yakaderedzwa zvakanyanya, iyo roller oparesheni inova yakanyanya kugadzikana uye yakagadzikana.Ultra-yakakwirira molecular uremu polyethylene ine simba rakanaka pakunyudzwa kwesimba uye kunyorovesa, izvo zvinogona kunyatso kudzikisa ruzha rwekushandisa uye kugonesa midziyo yekufambisa kuti ipedze kureba kureba, hukuru hukuru, uye nekumhanya-mhanya mashandiro.Zvisinei, tichifunga zvikanganiso zvesimba rakaderera re polyethylene raw materials, zvakakosha kuti upfuure kuverenga kwakadzikama uye kuedza.
(2) Nekuti iyo yekupedzisira-yakakwirira molecular uremu polyethylene roller ine chitarisiko chekusanamatira, isina-ngura, uye yekuzvizora, ine dziviriro iri nani yekufambisa, kunyangwe iyo roller yakakuvadzwa uye isingakunguruke, haiite. kukuvadzwa.Bhandi rekutakurahaisi nyore kupfeka uye hupenyu hwebasa hwebhandi rekutakura,conveyor roller
