Chii chinonzi?
Pe, inozivikanwa sePolyethylene (Polyethyle), ndeimwe yezvinhu zvepurasitiki zvakanyanya kushandiswa pasi. Nekuda kweiyo yakanakisa yemuviri uye yemakemikari zvivakwa, pezvinhu zvigadzirwa zvinoshandiswa mune dzakasiyana siyana maindasitiri. Kubva pamabhegi ekuputika ekuputika zvinhu, polyethylene anenge kwese kupi. Munyaya ino, isu tichaongorora zvakadzama kuti pe nderipi, mhando dzayo, zvivakwa uye nzvimbo dzekushandisa.
1. Chemical chimiro uye kuiswa kwePe
Pe ndiyo dentmplastic resin yakaumbwa kubva kuEndlyene Monomers kuburikidza nePolymerisation Reaction. Zvichienderana nekumanikidzwa uye tembiricha mamiriro panguva yePolymerisation process, pe zvinhu zvinogona kuiswa mumhando dzinoverengeka:
Low Density Polyethyle (LDPE): Iyi mhando yezvinhu zvakarongedzwa zvakasununguka pakati pemaketani ane manyorerwo uye anowanzoitwa mukugadzirwa kwemafirimu epurasitiki, kurongedza zvinhu, uye mafirimu ekurima .

Yakakwira density polyethyle (HDPE): Maketani eHdpe yeHDPE yakarongedzwa kwazvo uye ine yakakwirira density uye ichiratidzira simba rakanyanya.

Linear low denity polyethylene (LDPE): LLDPE orgylenity density polyethyle ine mutsara molecular chimiro chinosanganisa kuchinjika kweLDPE neSimba reHDPE. Zvinowanzoshandiswa kugadzira firimu, mabhegi epurasitiki uye maindasitiri ekugadzira zvinhu.

2. Maitiro makuru ePe zvigadzirwa
Pe Chinyorwa chine huwandu hwechinhu chinoshamisa chemuviri uye chemakemikari zvinokonzerwa nemhando yayo yakasarudzika molecular, iyo inoita kuti ibudise munzvimbo dzakasiyana siyana.
Kemical Resistance: Pe Chinyorwa chine simba rakanakisa kune yakawanda acids, Alkalis

Kunetseka kwakanaka uye kusimba kwesimba.

Zvivakwa Zvakanakisa Zvekushandisa Zvivakwa: Pe zvinhu ivhu rakanakisa emagetsi insulator, iyo inoita kuti ishandiswe zvakanyanya sechidimbu cheshuwa chemazita uye waya.

Mvura yakadzika yekunyura

3. Nzvimbo dzekushandisa dzePE zvinhu
Nekuda kwezvivakwa zvavo zvakasiyana uye zvakanakisa, Pe zvinhu zvinonyanya kuita basa rakakosha muhupenyu hwezuva nezuva uye muindasitiri. Kuziva izvo zvinotibatsira kuti tinzwisise zviri nani huwandu hwayo hwakawanda hwekushandisa muminda dzakasiyana:
Kugadzira Indasitiri: PE Zvigadzirwa zvinoshandiswa zvakanyanya mukugadzira mafirimu epurasitiki, mabhegi ekurongedza maFirimu.

Kuvaka uye pombi indasitiri: HDPE inowanzoshandiswa mukugadzirwa kwemapipi emvura, gasi pipi nemapipi emakemikari nekuda kwekumanikidzwa kwayo uye kupokana kwakanyanya.

Zvigadzirwa zveimba: Zvizhinji zvezuva nezuva zvigadzirwa, zvakadai semabhegi, mabhegi emarara uye midziyo yekuchengetedza chikafu, yakagadzirwa kubva pherethyle.

4. Kudzivirirwa kwezvakatipoteredza uye kudzokororwa kwezvinhu zvigadzirwa
Pasinei nezvakawanda zvakanakira, kushandiswa kwakapararira kwePE zvinhu kwakaunza matambudziko epakatiripo. Nekuti hazvisvibise zvinhu zviri nyore, zvakaraswa zvigadzirwa zvinogona kuve nekureba kwenguva refu kukanganisa pane iyo Ecosystem. Polyethlene zvinhu zvinogadziriswa. Kuburikidza nenzira dzemuviri kana dzemakemikari, dzakaraswa zvigadzirwa zvigadzirwa zvinogona kuzvidzwa muzvitsva, nokudaro zvichideredza kukanganisa kwenzvimbo.
Mhedziso
Kuburikidza nekuongororwa pamusoro apa, isu tine nzwisiso yakakwana yenhau ye "Chii chinonzi PERIPE". Sezvinonyanya kukosha zvepurasitiki zvinhu, polyethylene inoshandiswa zvakanyanya mumasango akasiyana siyana nekuda kweiyo yakasarudzika mamiriro uye zvakanakisa zvivakwa. Kunyangwe kushandisa kwayo kunokanganisa matambudziko eponeswa, manejimendi ekusimudzira ezvinhu zvinhu zvinogona kuwanikwa kuburikidza nekunyepedzera kudzokorodza.
