Pakati pekuwedzera kuri kuita R&D uye hunyanzvi mukugadzira mapurasitiki einjiniya, pepa re polyethylene (HDPE) rakanyanya kusimba, nekuda kwekushanda kwaro kwepamusoro, riri kuva chinhu chinosarudzwa mumabasa ekuvaka, mainjiniya emakemikari, kuchengetedzwa kwezvakatipoteredza, uye michina. Nezvakanakira zvaro zvikuru zvakaita sekusimba kwakanyanya, kuramba ngura, uye nyore kugadzira,Pepa reHDPEyakachinja mamiriro ezvinhu einjiniya.
I. Kushanda Kwepamusoro-soro
1. Simba Rakakwirira uye Kuramba Kuora
Pepa reHDPEine huwandu hweinenge 0.94-0.98 g/cm³ uye crystallinity yakakura ye80%. Maketani ayo akazara nemasero anopa hunhu hwakanaka hwemakanika. Simba rayo rekudhonza i ≥20 MPa, simba rayo rekuchinjika ≥24 MPa, uye kureba kwayo pakuputsika kunogona kusvika 500%, zvichiita kuti ikwanise kumira mitoro yakakwira uye kuratidza kusimba kwakanyanya. Uyezve, pepa reHDPE rinodzivirira acidic nealkaline solutions dzakadai sehydrochloric acid nesodium hydroxide, pamwe neorganic solvents, patembiricha yemumba. pa60°C, pepa reHDPE harizokanganise, Izvi zvinoita kuti ive sarudzo yakakwana yekushandisa muminda yemakemikari nekuchengetedza nharaunda.
2. Inochengetedza nharaunda uye kuchengetedzeka
HDPE haina chepfu uye haina hwema, uye yapasa zvitupa zvakawanda zvekuchengetedza nharaunda uye zvekuchengetedza chikafu, zvichiita kuti ive chinhu chinochengetedza nharaunda. Ndiyo sarudzo inosarudzwa pakucheka mapepa mumafekitori ekugadzira chikafu nenzvimbo dzekuurayira.
II. Mashandisirwo Akawanda
1. Magadzirirwo Ezvivakwa Nemba
Sheti reHDPE rinoshandisa nzira ye "extrusion molding + precision embossing", zvichiita kuti rive nechimiro chisina musono chinobatana zvakanaka nesheti pachayo, zvichidzivirira kubvaruka nekutsemuka. Kuwedzerwa kwemasterbatch isingapindi UV kunodzivirirawo kubva kuUV, zvichiita kuti irambe iripo pabasa rekunze. Yakakodzera kushongedza kunze kwechivakwa uye mukati.
Mapepa esandwich eHDPE ane layer double-layer ndiwo anonyanya kufarirwa pakushandisa panhandare yekutamba.
2. Maindasitiri neKutakura Zvinhu
Mapepa eHDPEanoshandiswa muindasitiri yemakemikari pakuisa matangi nemapaipi.
Muchikamu chezvekufambisa, anoshandiswa semasherufu, mapallet, matruck liner, marasha bunker liner, uye chute liner. Hunhu hwawo hwakareruka, hunodzivirira kupera, hunodzivirira kukuvadzwa, uye hunoderedza mvura hunowedzera kushanda kwawo zvakanaka.
Mameti ekudzivirira pasi eHDPE akareruka uye haaparadzi ngura, zvichiita kuti ashandiswe zvakanyanya mukugadzira migwagwa, kudiridza kwekurima, uye kuvaka.
Nekufambira mberi muhunyanzvi hwekugadzira mapurasitiki, dhizaini nekugadzirwa kwemapepa eHDPE zviri kuramba zvichivandudzwa. Mune ramangwana, mapepa eHDPE achakura kuita kuti zvive nyore, zvishande, uye zvigadziriswe kuti zvienderane nezvinodiwa zvakasiyana-siyana. Nekusanganiswa kwayo kwakakwana kwekushanda uye mashandisirwo, mapepa eHDPE ari kuchinja zvakanyanya mumunda wepurasitiki itsva dzeinjiniya.
Nekufambira mberi muhunyanzvi hwekugadzira mapurasitiki, dhizaini nekugadzirwa kwemapepa eHDPE zviri kuramba zvichivandudzwa. Mune ramangwana,Mapepa eHDPEichavandudza zvinhu kuti zviite kuti zvinhu zvireruke, zvishande zvakanaka, uye zvigadziriswe kuti zvisangane nezvinodiwa zvakasiyana-siyana. Nekusanganiswa kwayo kwakakwana kwekushanda uye mashandisirwo, mapepa eHDPE ari kuchinja zvinhu zvakanyanya mumunda wepurasitiki itsva dzeinjiniya.
Ingava mukuvaka, maindasitiri, kuchengetedzwa kwezvakatipoteredza, ndege, kana mamwe mabasa, mapepa eHDPE, nekushanda kwawo, hushamwari hwezvakatipoteredza, uye hunyanzvi, ari kuwedzera mikana yehupenyu hwemazuva ano. Kusarudza mapepa eHDPE zvinoreva kusarudza remangwana rinoshanda uye rinogara kwenguva refu.
