Zomwe Zili Zotetezeka Kuposa Makapu Amadzi Apulasitiki

Zomwe Zili Zotetezeka Kuposa Makapu Amadzi Apulasitiki

M'dziko lamasiku ano lofulumira, ubwino wa makapu amadzi apulasitiki amalandiridwa bwino. Komabe, mkati mwazosavuta izi pali mafunso ambiri okhudza chitetezo chawo, makamaka okhudza zida zomwe amapangidwa. Nkhaniyi ikufuna kugawa ndi kufananiza zida zapulasitiki zamtundu wa chakudya zomwe zimagwiritsidwa ntchito popanga kapu yamadzi, kuwunikira mbiri yawo yachitetezo komanso zomwe zimakhudza thanzi la munthu.

Mawu Oyamba

Makapu amadzi apulasitiki aphatikizana mosasunthika m'miyoyo yathu yatsiku ndi tsiku, akugwira ntchito ngati zombo zofunika kwambiri kuti hydrate. Komabe, pamene ogula akuzindikira kwambiri za thanzi ndi chilengedwe, chitetezo cha makapuwa chikuyang'aniridwa. Kumvetsetsa ma nuances azinthu zosiyanasiyana zamapulasitiki zomwe zimagwiritsidwa ntchito popanga makapu ndikofunikira kuti tisankhe mwanzeru zomwe zimayika patsogolo thanzi komanso kukhazikika.

Polyethylene Terephthalate (PET)

Polyethylene terephthalate (PET) ndi pulasitiki yogwiritsidwa ntchito kwambiri yomwe imadziwika chifukwa chomveka bwino, yopepuka, komanso yobwezeretsanso. Makapu amadzi a PET amayamikiridwa chifukwa cha kusavuta kwawo komanso kutsika mtengo, komwe nthawi zambiri amapezeka m'makina ogulitsa, m'malo ogulitsira, ndi zochitika. Ngakhale kuti PET nthawi zambiri imaonedwa kuti ndi yotetezeka kuti igwiritsidwe ntchito kamodzi kokha, pali nkhawa zokhudzana ndi kuthekera kwake kutulutsa mankhwala, makamaka pamene akutentha kwambiri kapena zakumwa za acidic. Momwemonso, makapu a PET ndi oyenera zakumwa zoziziritsa kukhosi kapena zotentha kuti muchepetse chiwopsezo cha kusamuka kwamankhwala.

Polypropylene (PP)

Polypropylene (PP) ndi pulasitiki yosunthika yomwe imayamikiridwa chifukwa cha kukana kutentha, kulimba, komanso kuchuluka kwa chakudya. Makapu amadzi a PP amagwiritsidwa ntchito kwambiri m'malesitilanti, malo odyera, ndi m'nyumba, amayamikiridwa chifukwa champhamvu komanso kukwanira kwa zakumwa zotentha ndi zozizira. PP ndi yokhazikika ndipo simachotsa mankhwala owopsa m'mikhalidwe yabwinobwino, zomwe zimapangitsa kukhala chisankho chokonda pazakudya ndi zakumwa.

Polystyrene (PS)

Makapu a polystyrene (PS), omwe nthawi zambiri amadziwika kuti Styrofoam, amakhala ndi maubwino angapo pamagwiritsidwe apadera. Kupepuka kwawo kumawapangitsa kukhala abwino ku zochitika, mapikiniki, ndi maphwando akunja, komwe kunyamula ndikofunikira. Kuphatikiza apo, makapu a PS amadzitamandira bwino zotetezera, kusunga zakumwa pa kutentha komwe kumafunikira kwa nthawi yayitali. Izi zimawapangitsa kukhala chisankho chomwe amakonda pakumwa zakumwa zotentha monga khofi ndi tiyi, kuwonetsetsa kuti zakumwa zimakhala zotentha komanso zosangalatsa. Komanso, makapu a PS ndi otsika mtengo, kuwapangitsa kukhala njira yothandiza pazochitika zazikulu kapena mabizinesi omwe akufunafuna mayankho azachuma popanda kusokoneza khalidwe.

 
Kuwunika Kuyerekeza kwa makapu apulasitiki a Food-Grade

Pankhani yosankha zipangizo zamagulu a zakudya za makapu a madzi, kusanthula kofananitsa kungathandize kufotokozera mphamvu ndi zofooka za njira iliyonse.

1. Chitetezo ndi Kukhazikika:

• Polyethylene Terephthalate (PET): Makapu a PET amapereka chitetezo chokwanira komanso chosavuta. Amavomerezedwa kwambiri kuti ndi otetezeka pakugwiritsa ntchito kamodzi kokha ndipo ndi oyenera zakumwa zoziziritsa kukhosi. Komabe, kusamala kumalangizidwa mukamagwiritsa ntchito makapu a PET okhala ndi zakumwa zotentha kapena zakumwa za acidic chifukwa cha kuthekera kwa kutulutsa mankhwala.
• Polypropylene (PP): Makapu a PP amadziwika chifukwa cha kukhazikika kwawo komanso kukana kutulutsa mankhwala, zomwe zimawapangitsa kukhala okonda zakudya ndi zakumwa. Ndizosunthika, zokhazikika, komanso zoyenera zakumwa zotentha komanso zozizira, zomwe zimawapangitsa kukhala osinthika pamakonzedwe osiyanasiyana.
• Polystyrene (PS): Makapu a PS amapereka mwayi wopepuka komanso kutsekemera kwabwino kwambiri kwamafuta. Makapu a PS amakhalabe otchuka pamapulogalamu apadera pomwe kukwera mtengo komanso kusungunula katundu kumaposa malingaliro azaumoyo anthawi yayitali.

2. Mphamvu Zachilengedwe:

• Polyethylene Terephthalate (PET): Makapu a PET amatha kubwezeretsedwanso, zomwe zimapangitsa kuti chilengedwe chichepetse chikatayidwa moyenera. Komabe, kugwiritsa ntchito kwawo kamodzi kokha komanso kubwezeretsedwanso kochepa kumabweretsa zovuta pakuthana ndi kuipitsidwa kwa pulasitiki.
• Polypropylene (PP): Makapu a PP amatha kubwezeredwanso ndipo amatha kusinthidwa kukhala zinthu zosiyanasiyana, kuchepetsa momwe amayendera zachilengedwe. Kukhalitsa kwawo ndi kuthekera kwawo kuti agwiritsidwenso ntchito kumawapangitsa kukhala chisankho chokhazikika poyerekeza ndi njira zina zogwiritsa ntchito kamodzi.
• Polystyrene (PS): Makapu a PS, ngakhale kuti ndi opepuka komanso otsika mtengo, amakhala ndi zovuta pakukonzanso komanso kukhudzidwa kwachilengedwe. Kuchepa kwawo kobwerezabwereza komanso kulimbikira kwachilengedwe kumatsimikizira kufunikira kwa njira zina zomwe zimayika patsogolo kukhazikika.

3. Kusinthasintha ndi Kuchita:

• Polyethylene Terephthalate (PET):Makapu a PET amapereka zosavuta komanso zotsika mtengo, kuwapangitsa kukhala oyenera zochitika, maphwando, komanso kugwiritsa ntchito popita.
• Polypropylene (PP): Makapu a PP amadziwika chifukwa cha kusinthasintha, kukhazikika, komanso kukwanira kwa zakumwa zosiyanasiyana, kuphatikiza zakumwa zotentha. Kulimba kwawo komanso kukana kutulutsa mankhwala kumawapangitsa kukhala chisankho chothandiza m'nyumba, m'malesitilanti, ndi m'malesitilanti.
• Polystyrene (PS): Makapu a PS amapambana m'malo omwe kusuntha kopepuka komanso kutenthetsa kwamafuta ndikofunikira, monga zochitika zakunja kapena malo ogulitsa zakudya mwachangu. Komabe, kukwanira kwawo kocheperako pakubwezeretsanso zinthu zina komanso nkhawa zomwe zingachitike pazaumoyo zimafunikira kuganizira mozama za njira zina.

Kusankha zinthu zamagulu a chakudya m'makapu am'madzi kumaphatikizapo kuyeza zinthu zosiyanasiyana, kuphatikiza chitetezo, kukhudzidwa kwa chilengedwe, kusinthasintha, komanso magwiridwe antchito. Ngakhale kuti njira iliyonse imakhala ndi ubwino wake, ogula ayenera kuika patsogolo zomwe amakonda komanso zomwe amakonda kuti apange zisankho zomwe zimagwirizana ndi thanzi lawo komanso zolinga zawo zokhazikika.

Makina opangira makapu apulasitiki ogwirizana

GtmSmart Cup Kupanga Makinaadapangidwa makamaka kuti azigwira ntchito ndi mapepala a thermoplastic azinthu zosiyanasiyana mongaPP, PET, PS, PLA , ndi ena, kuwonetsetsa kuti muli ndi mwayi wokwaniritsa zosowa zanu zopangira. Ndi makina athu, mutha kupanga zotengera zapulasitiki zapamwamba zomwe sizongosangalatsa komanso zokomera chilengedwe.

Mapeto

Kaya kuyika patsogolo chitetezo, kukhazikika kwa chilengedwe, kapena kuchitapo kanthu, ogula amatha kupanga zisankho zodziwikiratu powunika ubwino ndi kuipa kwa chinthu chilichonse. Kuphatikiza apo, kupita patsogolo kwaukadaulo ndi njira zopangira kukupitilizabe kupititsa patsogolo luso lopanga makapu apulasitiki, zomwe zimapereka mwayi wothana ndi zovuta zachitetezo ndi chilengedwe. Pokhala odziwitsidwa ndikuganiziranso kukhudzika kwa zosankha zawo, ogula atha kuthandizira kukhala ndi tsogolo lotetezeka komanso lokhazikika lakumwa kapu yamadzi yapulasitiki.
