Maaddada PLA si buuxda ma 100% bayoolaji kartaa???

Waxaa saameeyay caalamka"Xayiraadda caagga ah"iyo"Mamnuuci caaga"Sharciyada, qaybo ka mid ah aduunka ayaa bilaabay inay soo rogaan xayiraad balaastik ah oo ballaaran iyo siyaasadaha mamnuucida bacaha gudaha ayaa si tartiib tartiib ah loo hirgeliyey. Baahida balaastikada si buuxda loo dumin karo ayaa sii socota inay koraan. Plastic si buuxda u dumin kara waxay leedahay faa'iidooyin aad u wanaagsan marka la barbar dhigo balaastikada kale ee la dumin karo, waxayna si tartiib tartiib ah u noqotay caan.

Waa maxay maadada PLA?

PLA polylactic acid, oo sidoo kale loo yaqaan polylactide, waxaa loola jeedaa polymer polyester-ka oo laga helay polymerizing lactic acid oo ah alaabta ceeriin ee ugu weyn. Caadi ahaan waxa laga sameeyaa istaarij ay soo jeediyaan khayraadka dhirta la cusboonaysiin karo (sida galleyda, cassava, iwm.). Waa nooc cusub oo ah walxo biodegradable ah oo dib loo cusboonaysiin karo.

Waa maxay sababta walxaha PLA ay 100% noolaha u noqon karaan?

PLA waa kheyraadka dhirta la cusboonaysiin karo, kaas oo leh biodegradability wanaagsan oo gebi ahaanba hoos u dhigi kara noolaha dabiiciga ah ka dib isticmaalka.
Polylactic acid waa polymer aliphatic hydroxy acid, kaas oo ah walxo adag oo ku jira xaalad dhalada heerkulka qolka, waxaana loo beddelaa kaarboon dioxide, CH4 iyo biyo hoos yimaada burburka unugyada yaryar. Waa walxo toosan oo si buuxda u noole rogrogmi karta.

Waa maxay faa'iidooyinka isticmaalka alaabta PLA?

Qalabka miiska ee PLA wuxuu noqon karaa 100% kaarboon dioxide iyo biyaha dabiiciga ah, xalinta dhibaatada wasakhowga cad ee xididka, ilaalinta deegaanka iyo helitaanka horumar waara.

Waqtigan xaadirka ah, sanduuqyada qadada ee caadiga ah sida sanduuqyada dibadda, sanduuqyada makhaayadaha, iyo sanduuqyada cuntada ee supermarket-ka ayaa inta badan ka samaysan walxo ku salaysan batroolka, habka wax-soo-saarka ayaa ka koobnaan doona waxyaabo badan oo lagu daro, kuwaas oo keeni kara kansar ku dhaca jidhka bini'aadamka. Doorashada walxaha PLA waxay u fiican tahay caafimaadkaaga.

Xaaladda deegaanka iyo siyaasadaha degdega ah: Marka loo eego tirokoobyada aan dhamaystirnayn, qiiqa kaarboon laba ogsaydh ee aduunka ayaa lagu soo waramayaa inay kor u kacdo 60°C sanadka 2030. Tani waa xog aad u xun. Ururka Ilaalinta Deegaanka Adduunka ayaa sidoo kale si adag ugu baaqaya xubnahooda inay fiiro gaar ah u yeeshaan deegaanka. Sidaa darteed, waa isbeddel lama huraan ah in lagu beddelo caagadaha la tuuri karo iyada oo dib loo isticmaali karo polylactic acid agab casho oo dhammaystiran oo biodegradable ah.

PLA waxay leedahay iswaafajin wanaagsan, hoos u dhac, sifooyin farsamo iyo astaamo jireed. Waxay ku habboon tahay hababka wax-soo-saarka ee kala duwan sida dharbaaxada iyo thermoplastic. Way fududahay in la farsameeyo oo si ballaaran loo isticmaalo. Warshadeenu waxay hadda soo saartaa Guryo, sida alaabta miiska, maddiibado, caws, baakadaha, koobabka, sanduuqyada qadada, iwm. Waxaanan taageernaa habeynta qaababka, qaababka, midabada, iwm.
