Kodi pe?
Pe, imadziwika kuti polyethylene (polyethylene), ndi imodzi mwazida zapulasitiki zomwe zimagwiritsidwa ntchito padziko lapansi. Chifukwa cha thupi lake labwino kwambiri komanso mankhwala, zopangira zidutswa zimagwiritsidwa ntchito m'mafakitale osiyanasiyana. Kuchokera m'matumba opangira ziphuphu, polyethylene pafupifupi kulikonse. Munkhaniyi, tifufuza mwatsatanetsatane za zomwe zili, zamtundu wake, katundu ndi malo ogwiritsira ntchito.
1. Kapangidwe ka mankhwala ndi gulu la pe
Pe ndi lotumphuka wopangidwa kuchokera ku ethylene monomers pochita polyrisation. Kutengera ndi kuteteza ndi kutentha kwa nthawi yomwe atumiza polymerisation, zopangira zidutswa zitha kutchulidwa m'mitundu ingapo:
Kuchulukitsa kotsika polyethylene (LDPE): Mtundu uwu wa People udalipo pakati pa unyolo wamtunduwu ndipo umakhala ndi mafilimu otsika.Le, ndipo amagwiritsidwa ntchito kwambiri popanga mafilimu apulasitiki, ndi mafilimu azaulimi .

Kuchulukitsa Kwambiri Polyethylene (HDPE): Ma unyolo a HDPA amakonzedwa ndikukula kwambiri, motero amawonetsa mphamvu bwino komanso kukana mabotolo.

Mizere yotsika polyethylene (LDEPE): LLDPE) Nthawi zambiri imagwiritsidwa ntchito popanga filimu, matumba apulasitiki ndi zida za mafakitale.

2. Makhalidwe Akulu a Magawo a Peop
Pempho ili ndi kuchuluka kwa zinthu zowoneka bwino komanso zamankhwala chifukwa cha kapangidwe kake kake, zomwe zimapangitsa kuti zizigwiritsa ntchito ntchito zosiyanasiyana:
Kukaniza kwamphamvu kwa mankhwala: People ili ndi kukana kwakukulu kwa asidi ambiri, alkalis, mchere komanso ma soll find, zomwe zimapangitsa kuti zikhale zabwino kwa mafakitale a mankhwala ndi mankhwala.

Kutsutsa kwabwino ndi kuchuluka kwa mphamvu: hdpe, makamaka, ali ndi mphamvu kwambiri ndipo amatha kupirira zovuta zapamwamba, zomwe zimapangitsa kuti zikhale zovuta zamakina opanga zinthu zofunika kuti zithetse katundu.

Zabwino kwambiri zowonjezera: Pepala la Perticy ndi wamagetsi wamagetsi, lomwe limapangitsa kuti lizigwiritsidwa ntchito kwambiri ngati ma aya ndi mawaya ndi mawaya.

Mafuta otsika madzi: pempho limakhala ndi mayamwidwe otsika madzi motero amasunga zinthu zake zachilengedwe.

3. Magawo ogwiritsa ntchito
Chifukwa cha mitundu yawo yosiyanasiyana komanso yabwino kwambiri, za zinthu zofunika pa moyo watsiku ndi tsiku komanso m'makampani. Kudziwa za pempho kumatithandiza kudziwa bwino ntchito zosiyanasiyana m'magawo osiyanasiyana:
Makonda ogulitsa: Zipangizo zomwe zimapezeka zimagwiritsidwa ntchito kwambiri popanga mafilimu apulasitiki, matumba a chakudya ndi mafilimu amalima.

Ntchito Zomanga ndi Zojambulajambula: hdpe nthawi zambiri zimagwiritsidwa ntchito popanga mapaipi amadzi, ma pipi la mafuta ndi ma pipi ya mankhwala chifukwa chokana kwambiri komanso kukana kutukuka.

Zogulitsa zapakhomo: Zogulitsa zamapulasitiki zatsiku ndi tsiku, monga zidebe, matumba osunga zinyalala ndi zonyamula zakudya, zimapangidwa kuchokera ku polyethylene.

4. Kuteteza zachilengedwe ndikubwezeretsanso kwa zinthu
Ngakhale kuti ali ndi zabwino zambiri, kugwiritsa ntchito zinthu kufalikira kwa tizilombo kwadzetsa mavuto azachilengedwe. Chifukwa sizimamugwetsa zinthu mosavuta, zomwe zimataya zimatha kukhala ndi zovuta kwa nthawi yayitali pachilengedwe. Zinthu za polyethylene zimabwezedwa. Kudzera mu njira zakuthupi kapena mankhwala, zinthu zotayidwa zimatha kuzimiririka pazida zatsopano, motero zimachepetsa mphamvu zachilengedwe.
Mapeto
Kudzera muyeso womwe uli pamwambapa, timamvetsetsa mwatsatanetsatane nkhani ya "Kodi Peto" ndi chiyani. Monga chofunika kwambiri cha pulasitiki kwambiri, polyethylene amagwiritsidwa ntchito kwambiri pamafakitale osiyanasiyana chifukwa cha kapangidwe kake ndi zinthu zabwino kwambiri. Ngakhale kuti amagwiritsa ntchito zovuta za chilengedwe, kasamalidwe ka zinthu kambiri kamatha kupezekanso kudzera mwanzeru.
