Khoom taw qhia
Polylactic acid ua los ntawm cov khoom siv txuas ntxiv dua tshiab xws li pob kws hmoov nplej. Nws tau tsis ntev los no tau qhia ua cov khoom siv rau cov lim luam yeeb, hloov cov lim cellulose acetate ib txwm siv. PLA cab rau cov lim luam yeeb muaj ntau yam uas xav tau thiab cov txiaj ntsig.
Khoom nta
Ua ntej ntawm tag nrho cov, PLA yog ib puag ncig tus phooj ywg cov ntaub ntawv, raws li nws yog biodegradable thiab compostable. Nws tuaj yeem muab pov tseg kom nyab xeeb hauv cov chaw ua liaj ua teb, qhov chaw uas nws yuav tawg mus rau lub sijhawm. Qhov no txhais tau hais tias cov lim luam yeeb ua los ntawm PLA tsis ua rau muaj kuab paug mus ntev ntawm cov chaw pov tseg thiab peb ib puag ncig.
Lwm qhov zoo dua ntawm PLA cab rau cov lim luam yeeb yog tias nws xa cov kev haus luam yeeb tshwj xeeb, zoo ib yam li cov lim dej cellulose acetate. PLA cab muab kev pom zoo heev thiab nyiam cov khoom tsis zoo xws li tar thiab nicotine, tawm hauv qab kev haus luam yeeb zoo dua thiab huv dua.
Tsis tas li ntawd, PLA cab tuaj yeem tiv taus cua sov, txhais tau tias nws tsis yaj lossis tso cov pa phem thaum cua sov. Qhov no ua kom ntseeg tau tias kev nyab xeeb thiab zoo ntawm kev haus luam yeeb tsis muaj kev cuam tshuam, thiab tsis muaj kev pheej hmoo ntawm kev raug mob lossis kev puas tsuaj.
Tsis tas li ntawd, PLA cab yog ib qho khoom siv tau zoo thiab muaj txiaj ntsig zoo rau cov lim luam yeeb. Nws yog ib qho yooj yim los tsim, xav tau lub zog tsawg dua thiab cov peev txheej los tsim dua li cov lim dej ib txwm siv, thiab tau yooj yim muaj nyob hauv khw. Qhov no ua rau nws yog qhov kev xaiv zoo thiab muaj txiaj ntsig zoo rau cov lag luam luam yeeb uas tab tom nrhiav txoj hauv kev los txhim kho lawv cov kev ua haujlwm ib puag ncig thiab kev tsim khoom.
Zuag qhia tag nrho, PLA cab rau cov lim luam yeeb yog qhov kev tsim kho tshiab zoo siab uas muaj ntau yam txiaj ntsig, suav nrog kev ruaj ntseg ib puag ncig, kev haus luam yeeb zoo dua, kev nyab xeeb, thiab kev ua haujlwm zoo. Raws li cov neeg siv khoom muaj kev txhawj xeeb txog lawv qhov chaw ib puag ncig, peb tuaj yeem cia siab tias yuav pom qhov kev xav tau ntau ntxiv rau biodegradable, cov khoom siv cog xws li PLA hauv ntau qhov kev lag luam, suav nrog luam yeeb.
