Pfupiso

Pepa rePolythylene PE 1000 rinowanzozivikanwa se ultra-high-molecular-weight, UHMW, kana kuti UHMWPE, ndeimwe yepurasitiki dzedu dzinonyanya kufarirwa dzeinjiniya. Rinodzivirira zvakanyanya kukweshwa, makemikari, kukuvadzwa uye kupfeka, uye harina simba rakawanda rekukweshana. UHMW haina chepfu, haina hwema, uye inodzivirira zvakanyanya kukweshana.

Pepa repurasitiki reUHMW rinowanzo gadzirwa kuita mitsetse yekupfekwa, machain guides uye zvikamu zvekuchinja uye ipurasitiki inozivikanwa mukugadzira chikafu uye mabhodhoro. Mhando dzakatarwa dzePE1000 dzinoshandiswawo mukubata zvinhu zvakawanda mumachute, mahopper nemarori ekurasira marara, zvichibatsira kuvandudza kufamba kwechigadzirwa uye kudzivirira kukanganiswa uye kukotama.

Zvinhu zvirimo

1. Kuvandudza kusimba kwesimbi. Chimwe chezvinhu zvinonyanya kushamisa zveUHMW polyethylene isimba rayo rekudzivirira kusimba kwesimbi, iro rinokosha zvikuru mumabasa akawanda einjiniya. Pakati pemapurasitiki ese, kusimba kwayo kusimba kwesimbi ndiko kwakanakisa, uye kunyangwe kusimba kwesimbi nguva dzose (senge simbi yekabhoni, simbi isingatsvi, bronze, nezvimwewo) hakuna kunaka seizvi. Sezvo huremu hwepolyethylene huchiwedzera, chinhu chacho chinoramba kusimba zvakanyanya.

2. Kuramba kusimba kwakanyanya. Simba rekusimba kwepolyethylene ine huremu hwakawanda hwemamorekuru rine chekuita nehuremu hwayo hwemamorekuru. Kana huremu hwemamorekuru hwaderera kupfuura mamiriyoni maviri, simba rekusimba rinowedzera nekuwedzera kwehuremu hwemamorekuru, uye rinosvika padanho repamusoro pamamiriyoni maviri. Mushure mekukwirira, simba rekusimba rinowedzera nehuremu hwemamorekuru. Izvi zvinodaro nekuti cheni yemamorekuru haina kujairika uye inodzivisa photocrystallization yayo, zvekuti pane nzvimbo yakakura isina chimiro mu macromolecule, iyo inogona kutora simba guru rekusimba.

3. Kukwana kwekukweshana kwakaderera. UHMWPE haipfeki zvakanyanya, ine kukweshana kwakaderera uye inozvizora yega, uye chinhu chakanakira mabheya, maslider uye ma lining.
Kushandiswa kwepolyethylene ine huremu hwakawanda sechikamu chekukweshana kwemidziyo hakungogone chete kuvandudza hupenyu husingatsvedzi, asiwo kuchengetedza simba.

4. Kudzivirira makemikari zvakanaka. Polyethylene ine huremu hwakanyanya hwemamorekuru ine huremu hwakanaka hwemakemikari. Kunze kwe nitric acid yakakangwa uye sulfuric acid yakakangwa, haizokanganiswi mune zvese mhinduro dze lye neacid, uye inogona kushandiswa mu hydrochloric acid yakakangwa patembiricha (80°C, Inogarawo zvakanaka mu<20% nitric acid,<75% sulfuric acid, uye inogara yakagadzika mumvura, yakasukwa nemvura.)
Zvisinei, polyethylene ine huremu hwakawanda kwazvo inorema zviri nyore kuzvimba muzvinhu zvinonhuhwirira kana kuti zvine halogenated (kunyanya kana tembiricha yakakwira), saka kutarisisa kwakakosha kunofanira kupihwa panguva yekuisa.

5. Kunyudzwa kwemvura kwakaderera zvikuru. UHMWPE ine mwero wakaderera wekunyudzwa kwemvura, inenge isinganyudzwe, haizvimbi mumvura, uye hainyudzwe zvakanyanya kupfuura nayiloni.

6. Hunhu hwekupisa. Zvichienderana nenzira yeASTM (mutoro 4.6kg/cm2), tembiricha yekukanganisa kupisa ndeye 85℃. Pasi pemutoro mudiki, tembiricha yebasa inogona kusvika 90℃. Muzviitiko zvakakosha, inobvumirwa kushandiswa patembiricha yakakwira. Polyethylene ine huremu hwakawanda chinhu chine kusimba kwakanaka, saka kuramba kwayo kwakaderera kwakanakawo, uye ichiri nedanho rakati rekuita patembiricha yakaderera ye -269 ° C, uye hapana chiratidzo chekupwanyika.

7. Hunhu hwemagetsi. UHMWPE ine hunhu hwakanaka hwemagetsi muhurefu hwekupisa hwakakura, simba rayo rekudzivirira kupisa i10-18CM, voltage yayo yekupwanyika i50KV/mm, uye dielectric constant yayo i2.3. Muhurefu hwekupisa nefrequency, hunhu hwayo hwemagetsi hunochinja zvishoma. Muhurefu hwekupisa hunodzivirira kupisa, yakakodzera kushandiswa sezvinhu zvekuvaka muinjiniya yemagetsi uye zvinhu mumapepa.

8. Polyethylene isina chepfu yakanyanya-yakakwira haina kunaka, haina chepfu, haina hwema, haina ngura, uye ine kufamba kweropa mumuviri uye inochinjika mumuviri. United States Food and Drug Administration (FDA) neUnited States Department of Agriculture (USDA) vanobvumira kuti ishandiswe kana ichisangana nechikafu nemishonga.
Hunhu hwayo, kunyanya kuramba kupfeka, kuramba kukanganiswa, uye kuzvizora mafuta, ndizvo zvakanakisisa pakati pemapurasitiki einjiniya.
