Kusankha chidebe choyenera cha zinyalala cha pulasitiki chakunja ndikofunikira kwambiri kuti chikhale cholimba, chothandiza, komanso chosamalira chilengedwe. Kaya ndi madera okhala anthu, malo amalonda, mapaki, kapena madera a mafakitale, kusankha koyenera kungathandize kukonza bwino kutaya zinyalala, kuchepetsa ndalama zokonzera, komanso kusunga ukhondo wa chilengedwe. Bukuli lidzafotokoza mwatsatanetsatane zinthu zofunika kuziganizira posankha zidebe za zinyalala za pulasitiki zakunja, kuphatikizapo kusankha zinthu, kapangidwe ka magulu, ndi kufananiza kukula, kukuthandizani kupanga chisankho chodziwa bwino.
Chinthu Chofunika Kwambiri 1: Kusankha Zinthu - Maziko a Kulimba
Zipangizo za zinyalala za pulasitiki zakunja zimatsimikizira mwachindunji nthawi yomwe zingagwiritsidwe ntchito, momwe zingagwiritsidwe ntchito, komanso chitetezo chake. Zipangizo zosiyanasiyana za pulasitiki zili ndi mawonekedwe osiyana, kotero ndikofunikira kuzigwirizanitsa ndi zochitika zinazake zogwiritsidwa ntchito.
1. Polyethylene Yokhala ndi Kachulukidwe Kakakulu (HDPE)
Popeza ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri, HDPE imakhala ndi kuuma kwambiri, kulimba kwambiri, komanso kukana kwambiri ma acid ndi alkali. Ndi yoyenera kusunga zinyalala za kukhitchini, zinyalala zapakhomo, ndi mitundu ina ya zinyalala zodziwika bwino. Ubwino wodziwika bwino wa HDPE ndi kukana kwake kutentha kochepa, komwe kumaletsa ming'alu ngakhale m'malo ozizira, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito panja m'madera ambiri.
2. Polypropylene (PP)
Zipangizo za PP zimakhala ndi mphamvu yolimbana ndi kutentha kwambiri poyerekeza ndi HDPE, zomwe zimatha kupirira kutentha kwambiri. Izi zimapangitsa kuti zikhale zoyenera kwambiri m'malo omwe madzi otentha kapena zinyalala zotentha kwambiri zingakumane, monga pafupi ndi malo odyera, ma canteen, kapena malo opangira chakudya. Komabe, ndikofunikira kudziwa kuti PP ili ndi mphamvu yochepa pang'ono kutentha kochepa, kotero sizingakhale chisankho chabwino kwambiri chogwiritsidwa ntchito panja m'madera ozizira kwambiri.
3. Polyvinyl Chloride (PVC)
PVC ndi pulasitiki yotsika mtengo, koma ili ndi kukhazikika kofooka. Imatha kutulutsa zinthu zovulaza ikakumana ndi kutentha kwambiri, zomwe zingabweretse mavuto ku chilengedwe ndi thanzi la anthu. Pakadali pano, PVC siigwiritsidwa ntchito kawirikawiri pa zinyalala zakunja zomwe zimakhudzidwa mwachindunji ndi zinyalala zapakhomo, ndipo sikulimbikitsidwa pazochitika zambiri zakunja.
Chinthu Chachiwiri Chofunika: Kapangidwe ka Magulu - Kupitirira "Kubwezerezedwanso" ndi "Zina"
Ndi kupita patsogolo kwa mfundo zogawa zinyalala, zitini zamakono zapulasitiki zakunja sizilinso zotengera zazikulu zokha. Kapangidwe kake ka magulu kamakhala ndi zinthu zoganizira bwino kuti zikwaniritse zosowa zosiyanasiyana zogwiritsidwa ntchito ndikuwonjezera luso logawa zinyalala.
1. Kuphatikiza kwa Zidebe Ziwiri/Zidebe Zitatu
Iyi ndi njira yodziwika bwino yogawa zinyalala. Kuphatikiza kofala kwambiri ndi monga “Zobwezerezedwanso + Zinyalala Zina” ndi “Zinyalala Zakukhitchini + Zinyalala Zoopsa + Zinyalala Zina.” Zitini za zinyalalazi zimagwiritsa ntchito mitundu yowala bwino (buluu pa zinthu zobwezerezedwanso, wobiriwira pa zinyalala zakukhitchini, wofiira pa zinyalala zoopsa, imvi pa zinyalala zina, ndi zina zotero), zomwe zimathandiza anthu kuzindikira mosavuta ndikusankha zinyalala molondola.
2. Kapangidwe Kokhala ndi Chivundikiro
Zitini za zinyalala zokhala ndi zivindikiro zimakhala ndi mphamvu yabwino kwambiri yotsekera, zomwe zingathandize kuchepetsa kufalikira kwa fungo. Zimathandizanso kuti madzi amvula asalowe m'chidebecho ndipo zimaletsa udzudzu ndi ntchentche kuswana, zomwe zimapangitsa kuti zikhale zoyenera kwambiri kusungira zinyalala za kukhitchini kapena kugwiritsidwa ntchito m'malo ozizira akunja.
3. Kutsegula Chivundikiro Choyendetsedwa ndi Mapazi
Kapangidwe kameneka kamalola ogwiritsa ntchito kutsegula chivindikirocho popanda kuchikhudza ndi manja awo, zomwe zimapangitsa kuti ukhondo ukhale wabwino kwambiri. Mtundu uwu wa chidebe cha zinyalala umagwiritsidwa ntchito kwambiri m'malo opezeka anthu ambiri omwe ali ndi ukhondo wambiri, monga zipatala, malo ogulitsira zinthu, ndi masukulu a ana aang'ono.
4. Zidebe Zolumikizidwa Zokhala ndi Mphamvu Yaikulu
Kawirikawiri amapezeka m'malo omwe anthu ambiri amadutsa monga mabwalo, malo okongola, ndi mabwalo amasewera, malo ambiri osungiramo zinthu amalumikizidwa pamodzi. Kapangidwe kameneka sikuti kamangosunga magulu omveka bwino komanso kamasunga malo, zomwe zimathandiza kuti ogwira ntchito zaukhondo azisonkhanitsa ndi kunyamula katundu pakati.
Chinthu Chachitatu Chofunika: Kufananiza Kukula - Sankhani Kutengera Zochitika Zogwiritsidwa Ntchito
Kukula kwa zinyalala za pulasitiki zakunja kumakhudza mwachindunji momwe zimagwirira ntchito komanso momwe zimagwiritsidwira ntchito m'malo. Kusankha kukula koyenera malinga ndi momwe zinthu zilili kungapewe mavuto monga kusakwanira kwa malo kapena kusakhalapo kwa malo ambiri.
1. Makonde a Anthu Onse/Malo Olowera a Zipinda
Mabokosi ang'onoang'ono a zinyalala okhala ndi zidebe ziwiri okhala ndi mphamvu ya malita 30-50 ndi oyenera pano. Ndi ang'onoang'ono ndipo satenga malo ambiri, zomwe zimapangitsa kuti anthu okhala m'deralo azitaya zinyalala tsiku ndi tsiku.
2. Misewu/Njira za Paki
Mabotolo a zinyalala apakatikati okhala ndi mphamvu ya malita 80-120 ndi omwe akulangizidwa. Mphamvu zawo ndi zochepa, zomwe zingakwaniritse zosowa za oyenda pansi ngakhale kuti sizili zazikulu kwambiri kuti zisakhudze kukongola kwa chilengedwe.
3. Mabwalo/Malo Okongola/Mabwalo Osewerera Sukulu
Malo omwe magalimoto ambiri amadutsa amafunika zitini zazikulu za zinyalala zokhala ndi mphamvu ya malita 150-240. Izi zitha kuchepetsa kuchuluka kwa zinyalala zomwe zimatengedwa ndi kunyamulidwa komanso kupewa zinyalala.
Kuti musankhe chidebe choyenera cha zinyalala cha pulasitiki chakunja, muyenera kuganizira bwino zinthu zitatu zazikulu: zipangizo, kapangidwe ka magulu, ndi kukula. Ikani patsogolo zinthu za HDPE kapena PP kutengera chilengedwe; sankhani kapangidwe koyenera ka magulu malinga ndi zofunikira pakusankha zinyalala ndi miyezo yaukhondo; ndipo gwirizanitsani kukula kwake ndi kuchuluka kwa magalimoto ndi malo omwe amagwiritsidwa ntchito. Potsatira mfundo izi, mutha kusankha chidebe cha zinyalala chomwe chili cholimba, chothandiza, komanso chosamalira chilengedwe, ndikupanga malo akunja aukhondo komanso okonzedwa bwino.
