Hoʻohana
- Hana ʻia ma ke ʻano he "mea hoʻoheheʻe honua" hana kiʻekiʻe e hoʻoheheʻe i nā mea maka fiber synthetic (e laʻa, polyacrylonitrile no nā fibers acrylic), nā resins plastic (e laʻa, PVC), a me nā mea waena lāʻau lapaʻau.
- Kōkua i nā hopena synthesis organik (e laʻa, ka hoʻololi nucleophilic) a me ka hoʻomaʻemaʻe lāʻau lapaʻau (e laʻa, ka unuhi ʻana, ka recrystallization).
- Hoʻohana ʻia i loko o nā uhi/ʻīnika e hoʻoheheʻe i nā resins a me nā mea hoʻoluʻu, e hoʻomaikaʻi ana i ka hoʻopili ʻana o ka uhi a me ka pālahalaha ʻana o ka ʻīnika.
- Hana ma ke ʻano he mea hoʻohui hopena a mea lawe catalyst paha i kekahi mau kaʻina hana kemika (e laʻa, nā hopena formylation).
ʻŌpala a me ka Hoʻouna ʻana
25KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
