PVA
Kū?ai nui PVA Polyvinyl Alcohol
Nānā huahana
?O ka polyvinyl alcohol (PVA) he polymer hiki ke ho?ohehe?e ?ia i ka wai i ke?oke?o ma?amau i ka flake, flocculent, a i ?ole ka pauka.
?O ka lua, nā hi?ohi?ona huahana
Hiki ke ho?ohehe?e ?ia i loko o ka wai ma nā ?ano wela like ?ole e hana i kahi hopena ?ike.
Ho?opili maika?i: loa?a ka hopena pa?a pa?a i nā ?ano mea like ?ole.
Ho?okumu ki?i?oni?oni maika?i loa: ?O ke ki?i i hana ?ia he ikaika ki?eki?e a me ka ma?alahi.
Palekana Solvent: I kekahi ?ano, hiki iā ia ke pale aku i ka ho?ohehe?e ?ana o nā solvents ma?amau.
Biocompatibility: ?A?ohe mea ?awa?awa a aloha i ke kino kanaka a me ke kaiapuni.
ho?ohana huahana
?oihana lole lole
Ho?ohana ?ia e like me ka warp sizing material e ho?omaika?i ai i ka ikaika a me ke kūpa?a ?ana o nā yarns.
?O ka pa?i ?ana a me ke kala ?ana i nā mea kōkua, kōkua i ka ho?opili ?ana i ka wai a me ka hā?awi like ?ana.
?Oihana pepa
E ho?onui i ka ikaika a me ka pale wai o ka pepa.
Pigment coating adhesive e ho?omaika?i i nā waiwai o ka pepa i uhi ?ia.
kahua pa?a
Ho?opili no ka lā?au, ka pepa, ka fiber a me nā mea ?ē a?e.
?Oihana kūkulu hale
?O nā mea ho?ohui sima e ho?omaika?i i nā waiwai o ka sima.
Kahua lapa?au
?O ka mea maka o ka capsule lā?au, ka mea kōkua o ka lā?au ophthalmic.
Ka?ina hana hana
Ho?omākaukau ?ia e ka alcoholysis o ka polyvinyl acetate.
Nā mana?o mākeke
Me ka pi?i nui o ka noi no nā mea hana ki?eki?e i nā ?oihana like ?ole, ākea ka mākeke no PVA. Ke alaka?i ?ia e ka ho?omaika?i ?ana i nā ?oihana ku?una e like me ka textiles a me ka hana pepa, a me ka ho?omohala ?ana i nā kahua e kū mai ana e like me ka biomedicine a me nā mea uila, ua mana?o ?ia kāna koi mākeke e ulu mau.
e ho?ohana i ka mālama ?ana
E pale i ka makū a me nā wela ki?eki?e ke mālama ?ia.
Ke ho?ohehe?e ?ia, pono e ho?omalu ?ia ka mahana a me ka wikiwiki o ka ho?oulu ?ana e hō?oia i ka ho?ohehe?e ?ana a ?a?ole pili ka hana.
E koho i nā hi?ohi?ona kūpono a me nā kiko?ī e like me nā koi noi like ?ole.
No ka la?ana, i ka ?oihana textile, pono e koho ?ia ?o PVA me ka viscosity kiko?ī a me ka degere alcoholysis e like me nā mea a me ke ka?ina hana o ke kaula; I ka ho?ohana ?ana i nā adhesives, pono e ho?oponopono ?ia ka ho?okumu ?ana a me ka ho?ohana ?ana i ka PVA e like me ke ?ano o ka adhesive.
I ka hō?ulu?ulu?ana, he kuleana ko?iko?i ka Polyvinyl alcohol i nā māhele he nui me kona mau waiwai kūikawā, e hā?awi ana i ke kāko?o ikaika no ka ho?omohala?ana i nā?oihana pili.
