Chii chinonzi PBAT uye chii chinonzi PABT

A. Chii chinonzi PBAT

PBAT inonzi thermoplastic biodegradable plastic.Iyo Poly (butyleneadipate-co-terephthalate).Iine maitiro ePBA nePBT.Iyo ine yakanaka ductility uye elongation panguva yekuzorora.Iyo ine yakanaka yekudzivirira kupisa uye kukanganisa maitiro;uyezve, ine yakanakisa biodegradability uye ndeimwe yeanonyanya kushanda uye musika-kuora zvinhu mu biodegradable mapurasitiki ekutsvagisa.

B.Ndeipi chimiro chePBAT

1) 100% biodegradable, yakasvibiswa mumvura uye carbon dioxide mukati memwedzi mitanhatu pasi pemamiriro ekugadzirwa kwemaindasitiri, maererano neEN13432 uye ASTM D6400 mitemo.

2) Kubva paPBAT yakagadziridzwa yakazara biodegradable zvinhu, isina starch, ine yakanaka processability, mechanical simba uye kupora.

3) Nemhando yepamusoro yezvakasikwa zvinhu, kuderedza petroleum-based raw materials uye carbon dioxide emissions

4) Yakanakisa yemuviri uye michina zvivakwa.

5) Kuwedzera nguva yekugadzirisa, zvirinani kuumba kugadzirisa, tembiricha senitivity inodzikiswa zvakanyanya

6) Inogona kugadziridzwa nekumhanya kwakanyanya pane yechinyakare extrusion midziyo, isina pre-yaomesa isati yagadziriswa

7) Nehunyanzvi hwekusanganisa gadziriso michina, inogona kuchinjika kugadzirisa zvigadzirwa zvinoenderana nezvinodiwa nevatengi

8) Yakanakisa chigadzirwa kuita kugadzikana, hupenyu hurefu hwesherufu

9) Iyo yakasvibirira inodzivirira kupisa-inodzivirira mhinduro kugadzikana, zvimedu zvezvinhu zvidzokororwe zvakanaka, zvinogona kumira tembiricha yakakwira uye shear yakasimba.

10) Haina plasticizers senge glycerin, kugadzirisa uye kuisa maitiro haina kunamira, haina mafuta.

11) Inogona kusangana neFDA, EC2002 uye zvimwe zvinodiwa zvekudya

.sherefu chigadzirwa che 20 micron kana kupfuura chinogona kusvika 12-18 mwedzi pasherufu nguva.

13) PBAT-based blended yakagadziridzwa zvigadzirwa, uye zvimwe biodegradable zvinhu zvakaita sePBS, PLA, PHA, PPC, starch, nezvimwewo zvine kuenderana kwakanaka, zvinogona kusanganiswa.

14) Ma polyolefins echinyakare akadai sePE, PP, PO nezvimwe zvinhu hazvienderane, hazvigone kusanganiswa.Inofanirwa kuchengetwa zvakasiyana kubva kune izvi zvinhu panguva yekugadzira nekugadzirisa.

15) Zvisiri-starch-based yakazara biodegradable zvinhu zvinogona kushandiswa kugadzira anotevera mabhegi akaora zvizere: mabhegi ekutenga, mabhegi evest, mabhegi emarara, masaga emarara, homwe dzakafuratira, mabhegi emaoko, mabhegi emaoko, mabhegi ezvekudya, mabhegi, mabhegi enhengo. , Mabhegi emarara echipfuwo, masaga etsvina yemhuka, masaga emarara emukicheni, mabhegi anozvinamira, mabhegi ekupfeka, mabhegi ekurongedza, mulch yekurima, firimu, magurovhosi, nezvimwe.
