Chidule

Pepala la polythylene PE 1000 lomwe nthawi zambiri limatchedwa ultra-high-molecular-weight, UHMW, kapena UHMWPE, ndi imodzi mwa mapulasitiki athu otchuka kwambiri.Amapereka kukana kwabwino kwambiri ku abrasion, mankhwala, kukhudzidwa ndi kuvala, ndipo amapereka kutsika kothandizana kwamakangano.UHMW ilinso yopanda poizoni, yopanda fungo, ndipo imagonjetsedwa kwambiri ndi ambiri.

Mapepala apulasitiki a UHMW nthawi zambiri amapangidwa kukhala mizere yovala, maupangiri a unyolo ndi magawo osinthika ndipo ndi pulasitiki yotchuka yauinjiniya pokonza chakudya ndi kuyika mabotolo.Magiredi enieni a PE1000 amagwiritsidwanso ntchito popanga zinthu zambiri zopangira mizere ya ma chute, ma hopper ndi magalimoto otaya, kuthandiza kupititsa patsogolo kayendedwe kazinthu ndikupewa kusokoneza ndi kubisala.

Mawonekedwe

1. Sinthani kukana kuvala.Chimodzi mwazinthu zochititsa chidwi kwambiri za UHMW polyethylene ndi kukana kwake kwamphamvu kwambiri, komwe kumakhala kofunikira kwambiri pamakina ambiri.Pakati pa mapulasitiki onse, kukana kwake kuvala kumakhala kopambana, ndipo ngakhale kuvala kokhazikika kwa zipangizo zambiri zazitsulo (monga carbon steel, zitsulo zosapanga dzimbiri, bronze, etc.) sikuli bwino.Pamene kulemera kwa molekyulu ya polyethylene kumawonjezeka, zinthuzo zimakhala zolimba kwambiri.

2. Kukana kwakukulu kwambiri.Mphamvu yamphamvu ya polyethylene yapamwamba kwambiri yama cell imagwirizana ndi kulemera kwake.Pamene kulemera kwa maselo kumakhala kochepa kuposa 2 miliyoni, mphamvu ya mphamvu imawonjezeka ndi kuwonjezeka kwa kulemera kwa maselo, ndipo imafika pachimake pafupifupi 2 miliyoni.Pambuyo pachimake, mphamvu yamphamvu imawonjezeka ndi kulemera kwa maselo.adzachepa.Izi ndichifukwa choti unyolo wa ma cell ndi wachilendo ndipo umalepheretsa photocrystallization yake, kotero kuti pali dera lalikulu la amorphous mu macromolecule, lomwe limatha kuyamwa mphamvu yayikulu.

3. Low friction coefficient.UHMWPE ndiyosamva kuvala, imakhala ndi mikangano yotsika komanso yodzipaka bwino, ndipo ndi chinthu choyenera kunyamula ma bushings, slider ndi linings.

Kugwiritsiridwa ntchito kopitilira muyeso kwa polyethylene yolemera kwambiri yama cell monga gawo la mikangano ya zida sikungowonjezera moyo wosamva, komanso kupulumutsa mphamvu.

4. Kukana mankhwala abwino.Polyethylene yapamwamba kwambiri yama cell imakhala ndi kukana kwa dzimbiri kwamankhwala.Kupatula chigawo cha nitric acid ndi sulfuric acid yambiri, sichidzawonongeka muzitsulo zonse za lye ndi asidi, ndipo zingagwiritsidwe ntchito mu hydrochloric acid yowonongeka pa kutentha (80 ° C, Imakhalanso yokhazikika mu <20% nitric acid, < 75% sulfuric acid, komanso imakhala yokhazikika m'madzi, kutsuka kwamadzimadzi.)

Komabe, ultra-high molecular weight polyethylene ndi yosavuta kutupa mu mankhwala onunkhira kapena halogenated (makamaka kutentha kwapamwamba), kotero chidwi chapadera chiyenera kuperekedwa panthawi yogwiritsira ntchito.

5. Mayamwidwe otsika kwambiri amadzi.UHMWPE ili ndi mlingo wochepa kwambiri wa mayamwidwe amadzi, pafupifupi osayamwa, satupa m'madzi, ndipo imayamwa kwambiri kuposa nayiloni.

6. Thermal katundu.Malinga ndi njira ya ASTM (katundu 4.6kg/cm2), kutentha kupotoza kutentha ndi 85 ℃.Pansi pa katundu wochepa, kutentha kwautumiki kumatha kufika 90 ℃.Muzochitika zapadera, zimaloledwa kugwiritsa ntchito kutentha kwakukulu.High molecular kulemera polyethylene ndi zinthu ndi kulimba kwambiri, kotero kukana ake otsika ndi zabwino kwambiri, ndipo akadali ndi digiri inayake ya ductility pa kutentha otsika -269 ° C, ndipo palibe chizindikiro cha embrittlement.

7. Mphamvu zamagetsi.UHMWPE ili ndi mphamvu zabwino kwambiri zamagetsi pamtundu wambiri wa kutentha, kukana kwake kwa voliyumu ndi 10-18CM, mphamvu yake yowonongeka ndi 50KV/mm, ndipo dielectric yake ndi 2.3.Pakutentha kwakukulu komanso pafupipafupi, mphamvu zake zamagetsi zimasintha pang'ono.Pazigawo zotentha zosagwira kutentha, ndizoyenera kwambiri kuti zigwiritsidwe ntchito ngati zida zamakina muumisiri wamagetsi ndi zida zamapepala.

8. Polyethylene yopanda poizoni yochuluka kwambiri ya molekyulu ndi yopanda pake, yopanda poizoni, yopanda fungo, yosawononga, ndipo imakhala ndi kayendedwe ka thupi komanso kusinthasintha kwa thupi.United States Food and Drug Administration (FDA) ndi dipatimenti ya zaulimi ku United States (USDA) amalola kuti izigwiritsidwa ntchito pokhudzana ndi chakudya ndi mankhwala.

Makhalidwe ake, makamaka kukana kuvala, kukana kukhudzidwa, komanso zodzipaka mafuta, ndizabwino kwambiri pakati pa mapulasitiki aumisiri.
