CHII CHINONZI PLA FILM?
Firimu rePLA i biodegradable and environment-friendly firimu rakagadzirwa kubva muchibage-based Polylactic Acid resin.organic sources sechibage starch kana nzimbe.Kushandisa zviwanikwa zvebiomass kunoita kuti kugadzirwa kwePLA kuve kwakasiyana kubva kune akawanda mapurasitiki, ayo anogadzirwa achishandisa mafuta efosi kuburikidza nedistillation uye polymerization yepetroleum.
Pasinei nekusiyana kwezvinhu, PLA inogona kugadzirwa uchishandisa michina yakafanana neye petrochemical mapurasitiki, zvichiita kuti PLA yekugadzira iite inodhura.PLA ndiyo yechipiri inogadzirwa bioplastic (mushure me thermoplastic starch) uye ine maitiro akafanana nepolypropylene (PP), polyethylene (PE), kana polystyrene (PS), pamwe nekuve biodegradeable.
Firimu rine kujeka Kwakanaka,Good tensile simba,uye kunaka Kuomarara uye kuoma.Mafirimu edu ePLA anopihwa zvitupa zvecompost maererano ne EN 13432 chitupa.
Firimu rePLA rinoratidza kuve rimwe remhando yepamusoro yekurongedza firimu muindasitiri inochinjika yekurongedza, uye ikozvino yakashandiswa mumapakeji emaruva, chipo, chikafu sechingwa nemabhisikiti, kofi bhinzi.
PLA INOGADZIRWA SEI?
PLA ipolyester (polymer ine ester boka) yakagadzirwa nemamonomeri maviri anobvira kana zvivharo zvekuvaka: lactic acid, uye lactide.Lactic acid inogona kugadzirwa nekuviriswa kwebhakitiriya kweiyo carbohydrate sosi pasi pemamiriro ekudzora.Mukugadzirwa kwemaindasitiri kwelactic acid, carbohydrate inosarudzwa inogona kunge iri chibage starch, midzi yemufarinya, kana nzimbe, zvichiita kuti basa racho rirambe riripo uye rikwanise kudzokororwazve.
ENVIRONMENTAL ADVANTAGE OF PLA
PLA inoodza pasi pemamiriro ekutengesa composting uye ichaparara mukati memavhiki gumi nemaviri, zvichiita kuti ive sarudzo yezvakatipoteredza kana zvasvika kumapurasitiki mukusiyana nemapurasitiki echinyakare ayo anogona kutora mazana emakore kuora uye kupedzisira agadzira microplastics.
Maitiro ekugadzira ePLA zvakare ane hushamwari kwezvakatipoteredza kupfuura iwo echinyakare mapurasitiki akagadzirwa kubva kune inopera zvisaririra zviwanikwa.Zvinoenderana netsvagiridzo, iyo kabhoni emissions yakabatana nePLA kugadzirwa kwakaderera ne80% pane iyo yechinyakare mapurasitiki (mabviro).
PLA inogona kudzokororwa zvakare sezvo inogona kuputsika kusvika kune yayo yepakutanga monomer ne thermal depolymerization process kana ne hydrolysis.Mhedzisiro ndeye monomer mhinduro inogona kucheneswa uye kushandiswa kune inotevera PLA kugadzirwa pasina kurasikirwa kwemhando.
