Mumaindasitiri ekubata zvinhu zvakawanda zvakaita sekuchera migodhi, kugadzira simbi, uye kugadzira magetsi, kuvharika kwesilo uye kusakara kwechute matambudziko maviri enguva refu anotambudza kugadzirwa, zvichikonzera kudhura kwakanyanya uye kuchengetedzeka kwemunhu. Zvinhu zvesimbi zvechinyakare zvagara zvichisangana nematambudziko akadai sekunamatira, ngura, kupera nekukurumidza, uye ruzha rwakanyanya. Polyethylene ine huremu hwakawanda (Ultra-high molecular weight polyethylene).UHMWPE) machira, ane simba rekudzivirira kupfekwa, simba rekudzivirira kukuvadzwa, simba rekuzvizora uye simba rekusanamira, ari kubuda zvishoma nezvishoma senzira yekubatanidza michina yemazuva ano yekuchera, zvichichengetedza kugadzikana uye kushanda zvakanaka kwemutsetse wekugadzira.
Kudzivirira uye Kukombama kweSilo: Siyanai ne "Kuvhara Matumbu"
Zvinhu zvakanyorova (matombo, marasha akanyorova, ivhu), kunyanya muzvikamu zvakaita sedenderedzwa, zvinonamira nyore nyore pamadziro emadziro, zvichiita maburi nemaburi, zvichiita kuti mvura isabude zvakanaka uye zvinoda kucheneswa nemaoko, izvo zvisingangoiti basa zvakanaka chete asiwo zvine njodzi huru.
Saka, kuisa machira eUHMWPE semachira emukati memadziro emasilo, kunyanya munzvimbo dzine conical uye dzinoburitsa mvura, kunogadzirisa dambudziko iri zvakakwana.
Munzvimbo yesimbi ine simbi yakawanda muJohannesburg, South Africa, mapepa edu eUHMWPE ane ukobvu hwe20mm akaiswa zvizere. Mushure mekuvandudzwa, kunamira kwakadzikira ne90%, zvichiita kuti zvinhu zvifambe zvakanaka.Pepa reUHMWPEyakachengetedza kambani kusvika mamiriyoni maviri emadhora pagore mukuchenesa silo uye mari yekurasikirwa nemidziyo.
Kuramba Kupfeka Kwemakirabhu uye Kuderedza Ruzha: Kugadzira "Nzira Yekumhanya Yakanyarara"
Matombo esimbi, marasha, uye tsvina zvinodonha nekumhanya kwakanyanya mumachute, zvichikonzera kurova kwakanyanya panzvimbo dzinodonhedzwa pasi. Machute esimbi anopwanyika nekukurumidza, anogadzira ruzha rwakanyanya, uye anoda kutsiviwa nguva nenguva.
Saka, takaisa machira eUHMWPE semachira anodzivirira kupfekwa papuratifomu yepasi pechute, pamaplate epadivi, uye pamusoro pezvinhu zvinokanganisa.
Takaisa ma linings panzvimbo huru yekuchinjisa shaft yemugodhi wemarasha muMexico City, tichitsiva maplate esimbi ekutanga anodzivirira kupera ane ukobvu hwe16mm nemapepa eUHMWPE ane ukobvu hwe30mm. Mushure mekuvandudzwa, hupenyu hwe lining hwakawedzera kubva pamwedzi mitanhatu kusvika pamakore anopfuura mashanu. Panguva imwe chete, ruzha rwekushanda rwakaderera kubva pamadecibel zana nemakumi maviri kusvika pasi pemadecibel makumi masere, zvichivandudza zvakanyanya nzvimbo yekushanda. Mutengo wese wekutsiva kamwe chete wakaderera pane weplate dzesimbi dzesimbi, zvichiwedzera hupenyu hwebasa uye zvichideredza kuwanda kwekutsiva. Panguva imwe chete, kudzikira kwemazinga eruzha kunoderedza mari yekutarisira hutano hwebasa.
Sechinhu chakakosha mumasilos nemachutes, mapepa eUHMWPE, nekuda kwenguva refu yebasa rawo, anoderedza mari yekutenga yevagadziri, anoderedza vashandi nemari yekugadzirisa, uye anoderedza kurasikirwa kwekugadzira nekuda kwenguva yekushanda inokonzerwa nekugadzirisa.
Machira eUHMWPE haaparare, haarove, anozvizora ega, uye haana kunamira zvachose, anodzivirira kuvharika kwezvinhu, anoderedza kuramba kwemvura, uye anovimbisa kuchengetedzeka uye hushamwari kune nharaunda, nokudaro zvichivandudza kushanda zvakanaka kwekugadzira.
KUBVA PAMUSOROPepa reUHMWPEs dzakagadzirirwa nzvimbo dzakaoma dzekushanda. Isu hatisi kungopa machira chete, asi seti yemhinduro yakakwana, yakarongeka inodzivirira kupera.
Kusapfeka zvakanyanya uye kusabatwa nechinhu cheUHMWPE kunoita kuti chikwanise kutsungirira kukanganiswa nejecha nematombo. Panguva imwe chete, kusabatwa nengura kunoita kuti chikwanise kushandiswa muzvinhu zvakasiyana-siyana zvemineral, zvinosanganisira acidic, alkaline, uye saline. Ruzha rwayo rushoma uye haruna chepfu, harunhuhwi zvinoita kuti ive yakachengeteka uye isingakuvadzi nharaunda.
Ukobvu hwemapepa edu eUHMWPE hunotangira pa8mm kusvika 260mm, zvichizadzisa zvinodiwa nevatengi vane simba rekupfeka rakasiyana-siyana. Nzvimbo dzedu dzekugadzira machira eCNC dzinogona kupa michina isina kujairika, ichipa maplate akazara emasilo econical uye maplate echute eelbow lining kuti maplate eUHMWPE aiswe zvakanaka. Tinopawo zvishandiso zvehunyanzvi zvekuchengetedza zvakaita semabhaudhi ecountersunk uye zvisungo zveceramic kuti ive nechokwadi chekuti kuiswa kwacho kwakachengeteka.

Mibvunzo Inowanzo bvunzwa
Mubvunzo 1: Mapepa edu eUHMWPE anodzivirira kupisa zvakadini? Anogona kushandiswa pazvinhu zvinopisa zvakanyanya here?
A: Tembiricha yekushanda kwenguva refu yemapepa edu eUHMWPE ndeye -260℃ kusvika +80℃. Anogona kutsungirira tembiricha iri pasi pe100℃, asi hatikurudzire kushandiswa kwenguva refu munzvimbo dzinopfuura 80℃. Zvisinei, kana zvinhu zvinopisa zvakanyanya zvikafungwa nezvazvo, tinogona kugadzirisa mapepa acho kuti aenderane nenzvimbo chaiyo yekushanda uye kusangana nezvinodiwa nevatengi.
Mubvunzo wechipiri: Kuisa kwakaoma here? Midziyo yakakosha inodiwa here pakuisa?
A: Kuisa kwacho kuri nyore uye hakudi michina yakakosha. Kutanga, tinogadzirisa mapepa zvichienderana nemifananidzo yemutengi tobva taenderera mberi nekuvaka. Mapepa acho anogona kuiswa tichishandisa mabhoti, welding, kana bonding. Tinopa mirairo yekuisa, madhirowa, uye zvisungo zvehunyanzvi. Maturusi ekucheka nekuboorera chete ndiwo anodiwa panzvimbo yacho.
Mubvunzo wechitatu: Ndezvipi zvakanakira zvePepa reUHMWPEzvichienzaniswa nemidziyo yeceramic?
A: Mapepa eUHMWPE ane mukana wekudzivirira kukuvadzwa zvakanyanya uye nyore kushandisa. Kunyange zvazvo mapepa eceramic akaomarara, haapfumbuki uye haagoni kutsungirira kukuvadzwa nezvinhu zvakakura. Uyezve, kuunganidzwa kwezvinhu kunowanzoitika pamajoini, zvichiita kuti kucheneswa kuve kwakaoma.
Mubvunzo wechina: Ndingasarudza sei ukobvu hweMapepa eUHMWPE?
A: Ukobvu hwemapepa hunoenderana nekuomarara, chimiro, mwero wekuyerera, kudonha, uye saizi yemidziyo yezvinhu zvacho. Kazhinji, mapepa ane ukobvu hwe30-70mm anoshandiswa kumachute liners ane simba guru uye nzvimbo dzesilo impact, nepo mapepa ane ukobvu hwe15-30mm anogona kushandiswa kumapanera emadziro esilo. Ehe, mainjiniya edu ane hunyanzvi achakupa mhinduro dzakanyanya dzisingaperi kubva pakupfeka zvichienderana nenzvimbo yako yeinjiniya.
