Polylactic acid (PLA)wani sabon abu ne mai tushe da sabuntar abubuwan lalacewa da aka yi daga albarkatun sitaci da aka samu daga albarkatun shuka mai sabuntawa kamar masara da rogo.
Ana sanya ɗanyen sitaci sacchared don samun glucose, wanda sai a haɗe shi da wasu nau'ikan don samar da tsaftataccen lactic acid. PLA fiber masarar masana'anta wanda ba saƙa ba sannan an haɗa shi da sinadarai don haɗa wani nau'in nauyin kwayoyin polylactic acid. Yana da kyau biodegradability. Bayan amfani, a ƙarƙashin takamaiman yanayi, ana iya lalata shi gaba ɗaya ta hanyar ƙwayoyin cuta a cikin yanayi, suna samar da carbon dioxide da ruwa ba tare da gurɓata muhalli ba. Wannan yana da matukar fa'ida don kare muhalli.PLA masana'anta mara saƙaana la'akari da wani abu mai dacewa da muhalli.
Ana yin fiber na polylactic acid daga kayan aikin noma na sitaci kamar masara, alkama, da beets na sukari, waɗanda aka haɗe su don samar da lactic acid, sannan kuma suna raguwa kuma suna narke ta hanyar juyawa. Polylactic acid fiber fiber ne na roba wanda za'a iya shuka shi kuma yana da sauƙin girma. Sharar gida na iya lalacewa ta dabi'a.
Ayyukan da ba za a iya lalata su ba.
Kayan albarkatun fiber na polylactic acid suna da yawa kuma ana iya sake yin su. Polylactic acid zaruruwa suna da kyau biodegradability kuma za a iya gaba daya bazu zuwa carbon dioxide da H2O a cikin yanayi bayan an jefar da su. Dukansu na iya zama albarkatun kasa don sitaci lactic acid ta hanyar photosynthesis. Bayan shekaru 2-3 a cikin ƙasa, ƙarfin PLA fibers zai ɓace. Idan aka binne shi tare da sauran sharar kwayoyin halitta, zai rube cikin 'yan watanni. Bugu da kari, polylactic acid yana hydrolyzed cikin lactic acid ta acid ko enzymes a cikin jikin mutum. Lactic acid shine samfurin rayuwa na sel kuma ana iya haɓaka shi ta hanyar enzymes don samar da carbon dioxide da ruwa. Saboda haka, polylactic acid zaruruwa ma suna da kyau bioacompatibility.
Ayyukan shayar da danshi
Filayen PLA suna da kyakkyawan shayar da danshi da aiki, kama da lalacewa. Ayyukan sha danshi kuma yana da alaƙa da ilimin halittar jiki da tsarin zaruruwa. Tsayin tsayin daka na filayen PLA yana da tabo marasa daidaituwa da ratsi masu katsewa, pores ko fasa, wanda zai iya haifar da tasirin capillary cikin sauƙi kuma yana nuna kyakykyawan shayarwa mai kyau, damshi da kaddarorin rarraba ruwa.

Yana da ƙananan flammability da wasu jinkirin harshen wuta; Ayyukan rini ya fi muni fiye da zaruruwan yadi na yau da kullun, ba mai jurewa ga acid da alkali ba, kuma mai sauƙin ruwa. A lokacin aikin rini, ya kamata a biya kulawa ta musamman ga tasirin acidity da alkalinity; Ƙarfin haƙuri ga ultraviolet radiation, amma mai yiwuwa ga photodegradation; Bayan sa'o'i 500 na bayyanar waje, ana iya kiyaye ƙarfin filaye na PLA a kusan 55% kuma suna da kyakkyawan juriya na yanayi.
Danyen kayan don samar da fiber na polylactic acid (PLA) shine lactic acid, wanda aka yi daga sitaci na masara, don haka ana kiran irin wannan nau'in fiber na masara. Ana iya yin shi ta hanyar yayyafa beets na sukari ko hatsi tare da glucose don rage farashin shirya polymers na lactic acid. Ana iya samun babban nauyin kwayoyin polylactic acid ta hanyar sinadarai polymerization na lactic acid cyclic dimers ko polymerization kai tsaye na lactic acid.
Kayayyakin da aka yi daga polylactic acid suna da kyakykyawan daidaituwar yanayin halitta, bioabsorbability, ƙwayoyin cuta da jinkirin harshen wuta, kuma PLA yana da juriya mai zafi a cikin polymers masu lalata thermoplastic.
Polylactic acid fiber za a iya bazu zuwa carbon dioxide da ruwa a cikin ƙasa ko ruwan teku. Lokacin da aka kone shi, ba ya sakin iskar gas mai guba kuma baya haifar da gurɓatawa. Fiber muhalli ne mai dorewa. Tushensa yana jin daɗi, yana da kyawu mai kyau, yana da juriya ga haskoki UV, yana da ƙarancin flammability, da kyakkyawan aikin sarrafawa.
