Nhau - Hadzingavhenekerwa Korn Starch muBioplastics: Ndeipi basa rayo?

Muhupenyu hwedu hwezuva nezuva, zvigadzirwa zvepurasitiki zviri ubiquitous. Nekudaro, nyaya dzekuwedzera dzezvakatipoteredza dzinokonzerwa nenhamba dzechinyakare dzakakurudzira vanhu kuti vatsvage dzimwe nzira dzinosiririsa. Apa ndipo panogara bioplostics patsva. Pakati pavo, chibage chinomirira chakakosha sechinhu chakajairika mune bioplastics. Saka, chii chaizvo chibvumirano checorstarch in bioplastics?

1.Ko chii chinonzi bioplastics?
Bioplastics mapurasitiki akagadzirwa kubva kune inovandudza zviwanikwa zvakadai sezvirimwa kana zvidhinha. Kusiyana purasitiki echinyakare, bioplastics inogadzirwa kubva pazvinhu zvinotsvuka, zvobva zvonzera kukanganisa kwezvakatipoteredza. Chibage chinomarara, pakati pavo, zvinowanzo shandiswa seimwe yezvikamu zvikuru zvezvikamu zvekuita bioplastics.

2.Tino basa rechibage mune bioplastics

Chibage starch kunyanya inoshanda mitatu mikuru mabasa:
Cornstarch inoita basa mukuvandudza, kudzikisira uye kugadzirisa maitiro ekugadzirisa mune bioplastics. Iyo polymer iyo inogona kusanganiswa nedzimwe biohandura polymers kana mapapu kuti aumbe zvivakwa zvakagadzikana. Nekuwedzera zvakakodzera zvekuwedzera kurwirira, kuomarara, kuchinjika uye huwandu hwekusvibisa hwe bioplastics kunogona kugadziriswa, zvichiita kuti vakwanise kuita zviitiko zvakasiyana zvekushandisa.
Kuwedzera Simba Mumhanzi: Kubatanidzwa kwehumwe starch kunogona kuvandudza kuomarara uye kusimba kwesimba kwe bioplastics, kuita kuti vasike.

Kuvandudza Kugadzirisa Kwekuita: Kuvapo kwechibharo kuraswa kunoita kuti bioplastics zvakanyanya kuiswa panguva yekugadzirisa, kufambisa kugadzirwa kwezvinhu zvakasiyana siyana zvakaumbwa.

Pamusoro pezvo, chibage chinonhuhwira zvakanaka biodegradability. Mumamiriro ezvinhu akakodzera emamiriro ekunze, microorganisms anogona kuputsa chibage chesimba kuita mishonga iri nyore, pakupedzisira ichiwana kusvibiswa kwakazara. Izvi zvinobvumira bioplastics kuti ishandiswe zvakasarudzika mushure mekushandisa, kudzora kusvibiswa kwezvakatipoteredza.

Nekudaro, chibage chechimwe chinopawo zvimwe zvinonetsa. Semuenzaniso, mune yakakwira-tembiricha kana yakakwirira-yekunyoroveswa nharaunda, bioplastics inowanzoita kurasikirwa nekugadzikana, ichikanganisa hupenyu hwavo uye kuita kwavo. Kuti ugadzirise nyaya iyi, masayendisiti ari kushanda pakutsvaga mahosi matsva kana kugadzirisa maitiro ekugadzira kuti asimudzire kupesana nekupokana nekunyorova kupokana ne bioplastics.

3.Application yeiyo chibage starch mune chaiyo bioplastics

Iko kushandiswa kwechibage starch mune chaiyo biolastiki inosiyana zvichienderana nezvinodiwa zvivakwa uye zvinoshandiswa kushandiswa kwechigadzirwa chekupedzisira. Heano manhamba mashoma:

Polylactic acid (Pla): Pla iri bioplastic inowanzoitika kubva kune chibage starch. Chibage chechibage chinoshanda seyakafa chikafu chekugadzirwa kweiyo lactic acid, iyo inobva yatanga kuumba pla. Pl yakasimbiswa nehombodo yechibage inoratidzira zvivakwa zvemakaniki, senge simba rakawanda uye zvinokanganisa kuramba. Uyezve, kuwedzera kwechibage starch kunogona kusimudzira iyo biodegradability yePla, ichiita kuti iite kuti iite kuti zvibodzwa zvinowanikwa zvinoitwa nenzvimbo zvakatemerwa, zvakadai sekuraswa cutlery, kurongedza chikafu, uye okurima mulch mafirimu.

Polyhydroyiykitaates Chibage chakarongedzwa nemhirizhonga nemazvo kuburitsa polyhydroxybuthory (PHB), inova rudzi rwepha. Phas inosimbiswa nehasha dzesimbi dzinowanzo kuve nekugadzikana kwekunyora uye michina. Idzi bioplastics dzinowana maficha mumatunhu akasiyana siyana, kusanganisira kurongedza, zvishandiso zvekurapa, uye zvekurima.

Starch-based Bioplastics: Mune zvimwe zviitiko, strarch starch yakapihwa zvakananga kuita bioplastics isina kudiwa kwekuwedzera matanho eblymerization. Starch-yakavakirwa bioplastics kazhinji ine musanganiswa wechibage, mapurasitiki, uye anowedzera kuti uvandudze maitiro uye end-shandisa zvivakwa. Idzi bioplastics dzinoshandiswa mukushandisa senge mabhegi ekurasa, midziyo yekudya, uye yakaipa tafura.

Kusanganisa nedzimwe boly bymers polymers kunogonawo kusanganiswa nedzimwe polyhydroyies Izvi zvinosangana zvinopa chiyero chesimba rekusimba, kuchinjika, uye biodegradability, kuita kuti vakwanise kuve vakasarudzika pakushandisa zvakasiyana siyana kubva pakurongedza pakurima.

Basa rechibage mu bioplastics rinopfuura nekuwedzera kushanda; Izvo zvakare zvinobatsira kudzikisira kutsamira pane zvetsika peturu-based mapurasitiki, kutyaira kukura kweco-hushamwari zvinhu. Nekufambira mberi technology, isu tinotarisira kuona zvimwe zvigadzirwa zvemhando yepamusoro zvivakwa zvichienderana nezviwanikwa zvinotsvuka senge strarch.

Mukupfupikisa, chidhori chibage chinotamba chikamu cheshuwa mune bioplastics, kwete kungosimudzira kugadzikana kwekugadzira mapurasitiki asiwo kusimudzira biodegradability yavo, nekudaro kuderedza mamiriro ekunze. Nekufambira mberi kwehunyanzvi hwekuenderera mberi uye kufambira mberi, bioplastics vakagadzirira basa rakakura mukuunza zvimwe zvakanakira nharaunda yedu yepasi.
