ʻO ka hale hana kaulana Poly (1-vinylpyrrolidone-co-vinyl acetate)/VP/VA CAS:25086-89-9
ʻO ka mea mua loa, ʻo kēia copolymer he mau waiwai hana kiʻiʻoniʻoni maikaʻi loa.Hiki iā ia ke hana i kahi kiʻiʻoniʻoni akaka me ka hoʻopili maikaʻi a me ka lōʻihi.ʻO kēia ka mea kūpono no nā uhi a me nā mea hoʻopili i hoʻohana ʻia i nā ʻano noi like ʻole me nā pena, nā varnish a me nā varnish.
Eia kekahi, hōʻike ka vinylpyrrolidone-vinyl acetate copolymers i ka solubility maikaʻi loa i ka wai a me nā ʻano mea hoʻoheheʻe organik.Hiki i kēia solubility ke hoʻohana ʻia ma ke ʻano he mānoanoa mānoanoa i nā ʻano hana like ʻole, me nā huahana mālama pilikino e like me nā gels lauoho, sprays a me nā lotions.ʻO nā waiwai adhesive maikaʻi loa o kēia copolymer e lilo ia i mea waiwai nui i ka hana ʻana i nā papa a me nā capsules no ka ʻoihana lāʻau.
Eia kekahi, hiki ke hoʻololi ʻia ka conductivity o vinylpyrrolidone-vinyl acetate copolymers e like me nā koi kikoʻī, e kūpono iā lākou no nā mea uila a me nā noi hoʻopili conductive.ʻO kona kūlike me nā substrate like ʻole e like me nā metala, plastics a me nā textiles e hoʻohui i kāna versatility a me ka pono.
Hoʻohui hou, vinylpyrrolidone-vinyl acetate copolymers he thermally stable a kūpaʻa i ka radiation UV, e hōʻoia ana i ka lōʻihi a me ka hana mau loa no nā noi waho.He koho maikaʻi kēia no nā pale pale ma nā hale, nā kaʻa a me nā lako uila.
I ka hōʻuluʻuluʻana, vinylpyrrolidone-vinyl acetate copolymers loaʻa nā waiwai hana kiʻiʻoniʻoni maikaʻi loa, solubility, conductivity uila, a me ke kūpaʻa wela, e hāʻawi ana i nā mea he nui no nā ʻoihana like ʻole.Loaʻa kāna mau noi mai nā uhi a me nā mea hoʻopili i nā huahana mālama pilikino a me nā mea uila.Ke hilinaʻi nei mākou e hui a ʻoi aku kā mākou vinylpyrrolidone-vinyl acetate copolymers i kāu mau manaʻo me ko lākou kūlana kiʻekiʻe a me ka hana mau.
