Mabhodhoro epurasitikivave chikamu chinokosha chehupenyu hwedu hwezuva nezuva.Tinoashandisa kuchengeta mvura, zvinwiwa, uye kunyange kuchenesa dzimba.Asi wakamboona here zviratidzo zvidiki zvakadhindwa pazasi pemabhodhoro aya?Vanobata ruzivo rwakakosha nezvemhando yepurasitiki inoshandiswa, mirairo yekudzokorora, nezvimwe zvakawanda.Mune ino blog, tichaongorora zvinorehwa nezviratidzo izvi uye kukosha kwazvo mukunzwisisa mapurasitiki atinoshandisa.
Mabhodhoro epurasitiki akanyorwa nechiratidzo chetriangular chinozivikanwa seResin Identification Code (RIC).Chiratidzo ichi chine nhamba kubva pa1 kusvika pa7, yakavharirwa mukati mekudzinganisa miseve.Nhamba yega yega inomiririra rudzi rwakasiyana rwepurasitiki, kubatsira vatengi uye zvivakwa zvekudzokorodza kuti vaone nekuzvironga zvinoenderana.
Ngatitange nechiratidzo chinowanzoshandiswa, nhamba 1. Inomiririra Polyethylene Terephthalate (PET kana PETE) - ipurasitiki yakafanana inoshandiswa mumabhodhoro ekunwa zvinyoro.PET inogamuchirwa zvakanyanya nemapurogiramu ekudzokorodza uye inogona kudzokororwa mumabhodhoro matsva, fiberfill yejaketi, uye kunyange kapeti.
Kuenderera mberi kune nhamba 2, tine High-Density Polyethylene (HDPE).Iri purasitiki rinowanzo shandiswa mumajugi emukaka, mabhodhoro ekugezesa, nemabhegi egirosari.HDPE inodzokororwa zvakare uye inoshandurwa kuita matanda epurasitiki, mapaipi, uye mabhini ekudzokorodza.
Nhamba 3 inomirira Polyvinyl Chloride (PVC).PVC inowanzoshandiswa mupombi dzepombi, mafirimu ezvokudya, uye blister packaging.Nekudaro, PVC haisi nyore kudzokororwa uye inoisa njodzi dzezvakatipoteredza panguva yekugadzira uye kuraswa.
Nhamba 4 inomiririra Low-Density Polyethylene (LDPE).LDPE inoshandiswa mumabhegi egirosari, kuputira kwepurasitiki, uye mabhodhoro anosvinwa.Kunyangwe ichigona kudzokororwa kune imwe nhanho, haasi ese mapurogiramu ekudzokorodza anoigamuchira.Mabhegi anogona kushandiswa zvakare uye firimu repurasitiki rinogadzirwa kubva kuLDPE yakadzokororwa.
Polypropylene (PP) ipurasitiki inoratidzwa nenhamba 5. PP inowanzowanikwa mumigaba yeyoghurt, mabhodhoro ebhodhoro, uye mashizha anoraswa.Iine nzvimbo yakakwirira yekunyungudika, zvichiita kuti ive yakanaka kune microwave-yakachengeteka midziyo.PP inodzokororwa uye inoshandurwa kuita marambi echiratidzo, mabhini ekuchengetedza, uye makesi ebhatiri.
Nhamba 6 ndeyePolystyrene (PS), inozivikanwawo seStyrofoam.PS inoshandiswa mumidziyo yekuburitsa, makapu anoraswa, uye zvekurongedza zvinhu.Nehurombo, zvakaoma kudzokorodza uye kusagamuchirwa nemapurogiramu mazhinji ekudzokorodza nekuda kwekuderera kwayo kukosha kwemusika.
Chekupedzisira, nhamba yechinomwe inombundira mamwe ese mapurasitiki kana musanganiswa.Inosanganisira zvigadzirwa zvakaita sepolycarbonate (PC) inoshandiswa mumabhodhoro emvura anogona kushandiswazve, uye mapurasitiki anogona kuparara akagadzirwa kubva mumiti-based zvinhu, uye Tritan zvinhu kubva kuEastman, uye Ecozen kubva kuSK kemikari.Nepo mamwe mapurasitiki e7 achishandiswazve, mamwe haasi, uye kuraswa kwakakodzera kwakakosha.
Kunzwisisa zviratidzo izvi uye mapurasitiki anoenderana anogona kubatsira zvakanyanya mukuderedza marara uye kukurudzira maitiro akakodzera ekudzokorodza.Nekuziva mhando dzepurasitiki dzatinoshandisa, tinogona kuita sarudzo dzine ruzivo pamusoro pekushandisazve, kudzokorodza, kana kurasa zvine hungwaru.
Nguva inotevera paunobata bhodhoro repurasitiki, tora kanguva kuti utarise chiratidzo pazasi uye funga nezve maitiro ayo.Rangarira, zviito zvidiki zvakaita sekudzokorodza zvinogona kuita mutsauko wakakura mukuchengetedza nharaunda yedu.Tose ngativavarirei kuti tive neramangwana rakasvibira uye rakasimba.
