Kodi manambala ndi zizindikiro pansi pa makapu amadzi apulasitiki zimatanthauza chiyani?

Chizindikiro cha manambala pansi pa kapu yamadzi ya pulasitiki nthawi zambiri chimakhala chizindikiro cha katatu chotchedwa "resin code" kapena "chizindikiritso chobwezeretsanso", chomwe chimakhala ndi nambala.Nambala imeneyi imaimira mtundu wa pulasitiki wogwiritsidwa ntchito m’kapu, ndipo mtundu uliwonse wa pulasitiki uli ndi zinthu zake komanso ntchito zake.Nawa zizindikiro zodziwika bwino za utomoni ndi mitundu ya pulasitiki yomwe imayimira:

#1 - Polyethylene terephthalate (PET):

Pulasitiki imeneyi imagwiritsidwa ntchito popanga mabotolo omveka bwino a zakumwa, zotengera zakudya ndi ulusi.Ndiosavuta kukonzanso ndipo nthawi zambiri amagwiritsidwa ntchito popaka zakudya ndi zakumwa.

#2 – High Density Polyethylene (HDPE):

HDPE ndi pulasitiki yolimba kwambiri yomwe imagwiritsidwa ntchito popanga mabotolo, zidebe, mabotolo otsukira, mabotolo odzikongoletsera ndi zinthu zina zapakhomo.Ili ndi kukana kwa dzimbiri bwino komanso kukana ming'alu.

#3 - Polyvinyl Chloride (PVC):

PVC ndi pulasitiki yomwe imagwiritsidwa ntchito popanga mapaipi, kukulunga pulasitiki, pansi, ndi zina zambiri.Komabe, ili ndi zinthu zapoizoni, choncho nthawi zina kusamala kumafunika poikonzanso ndi kuitaya.

#4 - Polyethylene Yotsika Kwambiri (LDPE):

LDPE ndi pulasitiki yofewa komanso yosagwira kutentha yomwe imagwiritsidwa ntchito popanga matumba apulasitiki, mafilimu onyamula, magolovesi otayika, ndi zina zambiri.

#5 – Polypropylene (PP):

PP ndi pulasitiki yomwe imagonjetsedwa kwambiri ndi kutentha kwambiri ndi mankhwala ndipo nthawi zambiri imagwiritsidwa ntchito popanga zotengera zakudya, mankhwala, zinthu zapakhomo, ndi zina zotero.

#6 – Polystyrene (PS):

PS nthawi zambiri amagwiritsidwa ntchito m'mapulasitiki a thovu, monga makapu a thovu ndi mabokosi a thovu, ndipo amagwiritsidwanso ntchito popanga zinthu zina zapakhomo.

#7 - Pulasitiki Zina kapena Zosakaniza:

Khodi iyi ikuyimira mitundu ina ya mapulasitiki kapena zinthu zophatikizika zomwe sizigwera m'magulu 1 mpaka 6 pamwambapa.#水杯# Gululi lili ndi mapulasitiki amitundu yosiyanasiyana, ena omwe sangakhale ophweka kukonzanso.
Makhodi a digitowa amathandiza anthu kuzindikira ndi kusankha mitundu yosiyanasiyana ya mapulasitiki kuti awabwezerenso, kuwakonza ndi kuwagwiritsanso ntchito.Komabe, dziwani kuti ngakhale mutakhala ndi nambala yozindikiritsa zobwezeretsanso, malo obwezeretsanso ndi malamulo amderalo atha kukhudza ngati mitundu ina ya pulasitiki ikhoza kubwezeretsedwanso.
