Kukanganiswa nenyika "Plastic Restriction” uye “Plastic Ban” mitemo, mamwe matunhu epasi atanga kuisa zvirambidzo zvakakura zvepurasitiki uye mitemo yekurambidza epurasitiki yakashandiswa zvishoma nezvishoma. Iko kudiwa kwemapurasitiki akaparara zvizere kuri kuramba kuchikura. PLA yakazara yakaora plastiki ine zvakatanhamara zvakanakira zvichienzaniswa nemamwe mapurasitiki anoparara, uye zvishoma nezvishoma yave yakakurumbira.

Chii chinonzi PLA zvinhu?

PLA polylactic asidhi, inozivikanwawo sepolylactide, inoreva polyester polymer inowanikwa ne polymerizing lactic acid seyakanyanya mbishi zvinhu. Kazhinji inogadzirwa kubva kune starch inokurudzirwa nezvinogadzirwazve zvirimwa (sechibage, mufarinya, nezvimwewo). Irwo rudzi rutsva rwezvezve biodegradable material.

Sei PLA zvinhu 100% biodegradable?

PLA inzvimbo inovandudzwa yechirimwa, ine yakanaka biodegradability uye inogona kuderedzwa zvachose nema microorganisms mune zvakasikwa mushure mekushandisa.
Polylactic acid is an aliphatic hydroxy acid polymer, iyo yakaoma zvinhu mugirazi mamiriro epamhepo tembiricha, uye inoshandurwa kuita kabhoni dioxide, CH4 uye mvura pasi pekuora kwehutachiona. Iyo yakajairika mutsara yakazara biodegradable zvinhu.

Ndeapi mabhenefiti ekushandisa PLA zvinhu?

PLA tableware inogona kuve 100% yakaora kuita kabhoni dhaidhirosi uye mvura mumasikirwo, kugadzirisa dambudziko rekusvibiswa kwakachena kubva pamudzi, kuchengetedza zvakatipoteredza uye kuwana budiriro inoenderera.

Parizvino, mabhokisi ekudya kwemasikati anoraswa akadai semabhokisi ekutora, mabhokisi eresitorendi, uye mabhokisi ezvekudya ezvitoro zvinonyanya kugadzirwa nepetroleum-based zvinhu, uye maitiro ekugadzira achange aine zvimwe zvinowedzera zvinogona kukonzera cancer mumuviri wemunhu. Kusarudza PLA zvinhu zvakanaka kune hutano hwako.

Mamiriro ezvakatipoteredza nekukasika: Zvinoenderana nehuwandu husina kukwana, kuburitswa kwecarbon dioxide pasi rose kunonzi kuchakwira kusvika pa60°C muna 2030. Iyi idata yakaipa. World Environmental Protection Organization iri kukurudzirawo zvakasimba nhengo dzaro kuti dziteerere zvakatipoteredza. Naizvozvo, itsika isingadzivisiki yekutsiva mapurasitiki anoraswa neanogona kushandiswazve polylactic asidhi yakazara biodegradable dinnerware.

PLA ine kugarisana kwakanaka, kuderera, mashandiro emuchina uye zvimiro zvemuviri. Inokodzera nzira dzakasiyana-siyana dzekugadzirisa senge blow molding uye thermoplastic. Zviri nyore kugadzirisa uye kushandiswa zvakanyanya. Fekitori yedu parizvino inogadzira Mhuri, senge tableware, mbiya, mashanga, kurongedzerwa, makapu, mabhokisi emasikati, nezvimwe. Uye isu tinotsigira kugadzirisa akasiyana maumbirwo, masitayipi, mavara, nezvimwe.
