Polylactic acid, kuma aka sani da polylactide, na dangin polyester ne.Polylactic acid (PLA) shine polymerized tare da lactic acid a matsayin babban albarkatun ƙasa.Kayan albarkatun kasa suna da yawa kuma ana iya sabunta su.Tsarin samar da polylactic acid ba shi da gurɓatacce, kuma samfurin na iya zama biodegradable, fahimtar wurare dabam dabam a cikin yanayi, don haka yana da manufa koren polymer abu.Polylactic acid (PLA) wani sabon nau'in abu ne na ƙwayoyin cuta.Ana yin ta ne daga kayan sitaci da aka samo daga albarkatun shuka mai sabuntawa (kamar masara) ta hanyar fermentation, sannan kuma a canza shi zuwa polylactic acid ta hanyar haɗin polymer.
Polylactic acid ya dace da busa gyare-gyare, gyaran allura da sauran hanyoyin sarrafawa.Yana da sauƙin sarrafawa da amfani da yawa.Ana iya amfani da shi don sarrafa kwantena abinci iri-iri, fakitin abinci, akwatunan abincin abincin azumi, yadudduka marasa saƙa, masana'antu da yadudduka na farar hula daga masana'antu zuwa farar hula.Sannan ana iya sarrafa shi cikin yadudduka na noma, masana'anta na kiwon lafiya, ƙura, samfuran tsabta, masana'anta masu tsayayya da UV na waje, yadudduka tanti, tabarmi, da dai sauransu. Hasashen kasuwa yana da ban sha'awa sosai.Ana iya ganin cewa kayan aikin injiniya da na jiki suna da kyau.
Menene fa'idodin PLA na albarkatun kasa?
1. Yana da kyau biodegradability.Bayan amfani, ana iya lalata shi gaba ɗaya ta hanyar ƙwayoyin cuta a cikin yanayi a ƙarƙashin takamaiman yanayi, kuma a ƙarshe yana haifar da carbon dioxide da ruwa, ba tare da gurɓata muhalli ba.Hanyar maganin robobi na yau da kullun yana ci gaba da konewa da konawa, wanda ke haifar da yawan iskar gas mai yawa a cikin iska, yayin da ake binne robobin polylactic acid (PLA) a cikin ƙasa don lalacewa, kuma carbon dioxide da aka haifar yana shiga kai tsaye. kwayoyin halitta na ƙasa ko kuma tsire-tsire suna shayar da su, wanda ba za a saki a cikin iska ba kuma ba zai haifar da tasirin greenhouse ba.
2. Kyakkyawan kayan aikin injiniya da na jiki.Yana da sauƙin sarrafawa, ana amfani dashi ko'ina, kuma yana da kyakkyawan fata na kasuwa.
3. Kyakkyawan dacewa da lalata.Hakanan ana amfani da shi sosai a fannin likitanci.
4. Polylactic acid (PLA) yayi kama da petrochemical roba robobi a cikin ainihin kayan aikin jiki kuma ana iya amfani dashi da yawa don kera samfuran aikace-aikacen daban-daban.Har ila yau, Poly (lactic acid) (PLA) yana da haske mai kyau da kuma nuna gaskiya, wanda yayi daidai da fim din da aka yi da polystyrene kuma ba za a iya samar da shi ta wasu samfurori masu tasowa ba.
5. Polylactic acid (PLA) yana da mafi kyawun ƙarfin ƙarfi da ductility, kuma ana iya samar da shi ta hanyoyi daban-daban na sarrafawa na kowa.Poly lactic acid (PLA) na iya zama samfura daban-daban bisa ga bukatun masana'antu daban-daban.
6. Fim ɗin poly (lactic acid) (PLA) yana da kyakkyawan yanayin iska, iskar oxygen da ƙarancin carbon dioxide, kuma yana da halayen wari.Kwayoyin cuta da ƙwayoyin cuta suna da sauƙin haɗawa da saman robobin da ba za a iya lalata su ba, don haka akwai shakku game da aminci da tsabta.Duk da haka, polylactic acid shine kawai robobi na biodegradable tare da kyawawan kaddarorin antibacterial da anti mold.
7. Lokacin da aka ƙone PLA, ƙimar zafi mai ƙonewa daidai yake da na takarda, wanda shine rabin na roba na gargajiya (kamar polyethylene).Bugu da ƙari, ba zai taɓa sakin mahadi na nitrogen, sulfide da sauran iskar gas masu guba ba.
