FAQ
Nīnau: He aha ka hoʻohana mua ʻana o ka delta-Valerolactone monomer?
A: He monomer nui ia i ka hana ʻana i nā polyesters biodegradable a me nā copolymers i hoʻohana ʻia i ka lāʻau lapaʻau, hoʻopili, a me nā noi ʻoihana.
Nīnau: Pehea ka ʻokoʻa me nā monomers petrochemical?
A: He mea bio-mea hoʻoheheʻe ʻia, ʻaʻole-ʻawaʻawa, a hana ʻia mai ka biomass corncob hiki ke hoʻololi ʻia, e lilo ia i koho palekana a hoʻomau.
Nīnau: He kūpono anei ka delta-Valerolactone no nā lāʻau lapaʻau?
A: ʻAe, ʻo kona maʻemaʻe kiʻekiʻe a me ka haʻahaʻa haʻahaʻa i kūpono no ka hoʻohana ʻana i nā polymers biomedical e like me nā sutures, implants, a me nā mea lawe lawe lāʻau.
Q: Hiki ke hoʻohana ʻia i ka hana polyurethane?
A: ʻOiaʻiʻo. Ma ke ʻano he ʻāpana palupalu co-monomer, hoʻonui ia i ka maʻalahi a me ka biodegradability i loko o ka bio-pahu TPU.
Q: Pehea e mālama ʻia ai ka huahana?
A: Pono e mālama ʻia i loko o nā pahu i hoʻopaʻa ʻia mai ka wela a me ka lā. Hāʻawi mākou i ka ʻeke i loko o nā pahu a i ʻole nā pahu i kūpono no ka -maʻamau a me nā hoʻouna nui.
Ka hopena
Hāʻawi ʻo Delta-Valerolactone monomer i kahi hui ikaika o ka hana a me ka hoʻomau no ka ʻoihana polymer hou. Hana ʻia mai ka biomass corncob hou, hiki iā ia ke hoʻohui i nā polymers biodegradable, bio{2}}compatible, a me -kiʻekiʻe. Inā hoʻohana ʻia i loko o nā mea lapaʻau, nā ʻilika hoʻomau, a i ʻole nā mea hana kiʻekiʻe, ʻo kēia monomer ke hoʻolalelale nei i ke ala no ka hana hou polymer ʻōmaʻomaʻo ma ka pae honua.
