Polyvinyl Alcohol PVA 2488

ʻAʻona Polyvinyl(PVA) 2488 he māka kikoʻī o PVA, a hōʻike pinepine ka helu helu i kekahi mau kikoʻī a i ʻole nā ​​hiʻohiʻona o kēia papa. ʻO PVA kahi polymer synthetic i hana ʻia e ka hydrolysis o polyvinyl acetate. ʻO PVA 2488, e like me nā māka ʻē aʻe o PVA, ua ʻike ʻia no kona hiki ke hoʻoheheʻe wai a me nā waiwai hana kiʻiʻoniʻoni. Eia kekahi mau hiʻohiʻona nui a me nā noi maʻamau e pili ana me PVA 2488:

PVA 2488 mau hiʻohiʻona:

1. Degere o ka Hydrolysis:

  • ʻO ke kiʻekiʻe o ka hydrolysis ma PVA 2488 e pili ana i ka nui o ka polyvinyl acetate i hydrolyzed e hana i ka waiʻona polyvinyl. Hiki i nā māka PVA like ʻole ke loaʻa i nā pae like ʻole o ka hydrolysis, e pili ana i kā lākou waiwai.

2. Kaumaha Molekala:

  • Loaʻa paha i ka PVA 2488 kahi paona molekala kikoʻī, e pili ana i kona viscosity a me kona hiki ke hana kiʻiʻoniʻoni.

3. ʻAno Kino:

  • Loaʻa ka PVA 2488 ma ke ʻano o ka pauka keʻokeʻo a keʻokeʻo.

Nā noi maʻamau:

1. Nā mea hoʻopili:

  • Hoʻohana pinepine ʻia ʻo PVA 2488 ma ke ʻano he mea koʻikoʻi i loko o nā mea hoʻopili like ʻole, me nā lāʻau adhesives a me nā paʻi pepa. Hāʻawi ia i ka ikaika paʻa maikaʻi a me ka maʻalahi.

2. Ka nui lole lole:

  • I ka ʻoihana textile, hiki ke hoʻohana ʻia ʻo PVA 2488 i ka hoʻohālikelike ʻana i ka nui e hoʻomaikaʻi i ka ikaika a me ka mālama ʻana i nā waiwai o nā wili.

3. Pepa Pepa:

  • Hiki ke hoʻohana ʻia ʻo PVA 2488 i ka ʻoihana pepa no ka uhi ʻana, hoʻonui i nā waiwai o ka ʻili a me ka paʻi ʻana o ka pepa.

4. Nā mea hana kūkulu:

  • Loaʻa paha iā PVA 2488 nā noi i loko o ka ʻoihana kūkulu, ʻoi aku ka mea hoʻohui i nā ʻano hana sima e hoʻomaikaʻi ai i ka pili a me ka maʻalahi.

5. Packaging:

  • Hoʻohana ʻia nā kiʻiʻoniʻoni PVA, me nā mea i hoʻokumu ʻia ma PVA 2488, i nā palapala hoʻopili wai-soluble.

6. Nā Lapaʻau Lapaʻau:

  • Hoʻohana ʻia ʻo PVA, ma ka laulā, i nā noi olakino, me ka hana ʻana i nā mīkina lima lima a ma ke ʻano he ʻāpana i nā ʻano lāʻau lapaʻau hoʻokuʻu ʻia.

7. Nā mea hoʻohuihui:

  • PVA 2488, me kona mau waiwai emulsifying, hiki ke hoohana ia ma ka hana ana i na emulsions.

Nā manaʻo:

1. Nā ʻōlelo kikoʻī:

  • ʻO ke koho o ka papa PVA, me ka PVA 2488, e pili ana i nā koi kikoʻī o ka noi i manaʻo ʻia. Hāʻawi nā degere like ʻole o ka hydrolysis a me nā paona molekala i nā ʻano like ʻole o ka hana.

2. Kaulike:

  • Ua koho pinepine ʻia ʻo PVA 2488 ma muli o kona kūlike me nā mea ʻē aʻe i loko o kahi hoʻolālā a me kona hiki ke hoʻokō i nā pae hana i makemake ʻia.

3. Nā Manaʻo Mea Hoʻolako:

  • He mea koʻikoʻi ka hana pū ʻana me nā mea hoʻolako a me nā mea hana PVA no ka loaʻa ʻana o ke alakaʻi i ka hoʻohana maikaʻi ʻana o PVA 2488 i nā ʻano hana like ʻole. Hiki i nā mea hoʻolako ke hāʻawi i nā ʻike i nā hoʻolālā hoʻolālā a me ka launa pū me nā mea hoʻohui ʻē aʻe.

I ka hōʻuluʻulu ʻana, ʻo PVA 2488 kahi papa kikoʻī o ka Polyvinyl Alcohol me nā hiʻohiʻona kūʻokoʻa e kūpono ai i nā noi like ʻole, ʻo ia hoʻi i nā adhesives, textiles, nā uhi pepa, nā mea hana, a me nā mea hou aku. Inā loaʻa iā ʻoe kahi pōʻaiapili kikoʻī a noiʻi paha, e hāʻawi ana i nā kikoʻī hou aku e hiki ai ke pane pololei.
