Paipu kila i hoʻopaʻa ʻia me ka polyurethane
ʻO ka paipu kila i hoʻopaʻa ʻia me ka polyurethane he huahana paipu kūpaʻa kiʻekiʻe i ka ʻaʻahu ʻia, kahi i hoʻohana nui ʻia i nā paipu hana mineral a me nā paipu hoʻoili huelo. Hoʻohana ka hale hana mana wahie fossil i ka paipu no nā ʻōnaehana wehe lanahu a me ka lehu, a no nā ʻoihana aila, kemika, sima a me ka palaoa.
Nā hiʻohiʻona
1. Kūpaʻa i ke kapa komo
2. Kāohi i ka Scaling
3. Ke kū'ē'ē i ka palaho
4. Ke kū'ē i ka ʻelemakule hydrolysis
5. Elasticity kiʻekiʻe
6. Ke kū'ē ʻana i ka haʻalulu mīkini
7. Hoʻoluʻu ponoʻī
Koho ʻo Arex i ka pūʻulu haku kiʻekiʻe me ke ʻano nano-modified e hoʻoikaika i ka hana o ka mea polyurethane. Hana ia i nā huahana i hoʻopaʻa ʻia i ka polyurethane me kahi ʻano kemika paʻa a hōʻike i kona hiki ke hoʻololi i ke kūlana hana.
ʻO ka paipu kila i hoʻopili ʻia me ka polyurethane, ʻo ia kekahi o nā palapala sila kūloko o nā huahana mining ma Arex, he mea kaulana ia a ke hoʻohana ʻia nei e kā mākou mea kūʻai aku mining.
