Ndi mabotolo ati amadzi omwe ali bwino: PET kapena polycarbonate?

Posankha mabotolo amadzi, anthu ambiri amalabadira kuti pali mitundu iwiri ikuluikulu pamsika - PET ndi polycarbonate. Lero tikambirana momwe mitundu iwiri ya biringanya imasiyanirana komanso nthawi yomwe kuli bwino kugwiritsa ntchito imodzi kapena imzake. Ndi kugula botolo la polycarbonate yogulitsa kapena tikupangirani zotengera za PET mu sitolo yapaintaneti ya Aquadevice. Kampaniyi sikuti imangopereka zinthu zambiri zosungira, zogwiritsa ntchito, komanso zonyamula madzi, komanso zida zosavuta komanso zoganiziridwa bwino, zomwe ndizofunikira kwambiri pakuyitanitsa zinthu zotere.

Mabotolo amadzi a PET

PET (polyethylene terephthalate) ndi thermoplastic, mtundu wofala kwambiri wa pulasitiki. Izi nthawi zambiri zimakhala ndi mawonekedwe owonekera, zimakhala zamphamvu, komanso zopepuka. Kutengera ndi mtundu wake, amagwiritsidwa ntchito kupanga mabotolo amadzi otayika komanso osinthika okhala ndi malita 11, malita 18,9, malita 19. Kupaka koteroko ndi kotsika mtengo komanso kosavuta kupanga, kotero mtengo wake ukhoza kutchedwa wotsika. Ndipo mabotolo a polyethylene terephthalate ndi opepuka kwambiri, motero amakhala osavuta kunyamula.

Ngati tilankhula za zofooka, ndiye kuti khalidwe la pulasitiki liyenera kuganiziridwa. Koma ngakhale zotengera zapamwamba kwambiri za PET sizomwe zimasungiramo madzi ndi zakumwa zina kwa nthawi yayitali. Mothandizidwa ndi kuwala kwa dzuwa kapena kusintha kwa kutentha, pulasitiki imatha kutulutsa ma microparticles, omwe angakhudze mtundu wamadzimadzi.

Mabotolo amadzi a polycarbonate

Polycarbonate ndi pulasitiki yapolima yapamwamba kwambiri yomwe imakhala yolimba komanso yolimba. Mabotolo a polycarbonate ndi mbiya zamadzi zogwiritsidwanso ntchito zamitundu yosiyanasiyana (11, 19, 18,9 malita), zomwe zidzatsimikizira kusungidwa kwake kwanthawi yayitali. Chidebe chamtunduwu chimalimbana ndi mizere ingapo yodzaza madzi, ndikupangitsa kuti ikhale yabwino kugwiritsidwa ntchito kangapo. Nkhungu sizimawonekera pamakoma a chidebecho, komanso zimatha kutsukidwa ndi zotsukira, kotero kuti biringanya zotere zitha zaka zingapo.

Kuphatikiza apo, polycarbonate imalimbana bwino ndi kusintha kwa kutentha, chisanu, kutentha, ndipo imakhala yolimba kwambiri, kotero imatha kugwiritsidwa ntchito kunyamula malita ambiri amadzi, kuwasunga, ngakhale kutentha kapena kuziziritsa (pogwiritsa ntchito chozizirira). Polycarbonate imateteza bwino madzi ku cheza cha ultraviolet, chomwe chimalepheretsa kukula kwa tizilombo momwemo.

Inde, muyenera kulipira zambiri pazikhalidwe zoterezi. Mabotolo awa ndi okwera mtengo kwambiri kuposa mabotolo a PET okhala ndi voliyumu yofanana mu malita. Ndipo amakhalanso ndi kulemera kwakukulu, komwe kungakhalenso kofunikira pazifukwa zina, monga mayendedwe.

Kuyerekeza kwa mabotolo a PET ndi polycarbonate. Ubwino ndi kuipa kwake

Kuti mumvetse zomwe zili zabwino kwambiri pazosowa zanu, tiyeni tiwone kusiyana kwakukulu pakati pa PET ndi polycarbonate:

chizindikiro	Mabotolo a PET	Mabotolo a polycarbonate
Mphamvu	Oyenera kugwiritsidwa ntchito kangapo pansi pa kutentha	Kupirira ntchito mobwerezabwereza mwangwiro, ngakhale ndi madzi otentha
Mtengo	Zotsika mtengo	Khalani ndi mtengo wokwera
Kutentha kukana	Kusamva kutentha kwapakati	Imapirira kutentha kwambiri
Moyo wa alumali wamadzi	M'masiku ochepa patsogolo	Wautali
Ubwino wosungira madzi	Zochepa pansi pazikhalidwe za chilengedwe	Chifukwa cha chitetezo chabwino ku kutentha kwakukulu ndi kuwala kwa ultraviolet

Ndi zinthu ziti zomwe PET ili yoyenera bwino, ndipo mabotolo amadzi a polycarbonate ndi ati?

Mitundu yonse iwiri ya zotengera ndizosankha zabwino zosungira ndikugwiritsa ntchito madzi, koma chilichonse chimakhala choyenera pazinthu zina chifukwa cha zabwino zake. Ngati mukufuna mabotolo kuti mugwiritse ntchito kamodzi, mayendedwe, kapena kusunga zakumwa kwakanthawi kochepa, gulani mabotolo a PET opepuka komanso otsika mtengo. Kuti tigwiritse ntchito nthawi yayitali, timalimbikitsa mabotolo a polycarbonate, chifukwa amakhala olimba kwambiri ndipo amapereka madzi odalirika osungiramo madzi popanda chiopsezo chotulutsa zinthu zovulaza. Chilichonse chomwe mungasankhe, tcherani khutu ku khalidwe lazogulitsa ndikuzigula kuchokera kwa ogulitsa odalirika omwe angatsimikizire chitetezo cha mankhwala.
