Ke hoʻohana ʻia nei ka papa hana ʻenehana ʻo PVP nā lole / fibre, nā mea hoʻopili, nā uhi / nā kiʻi pena, nā mea holoi lole holoi, nā mea ʻoni, nā pālolo a me nā ʻoihana ʻenehana hi.
* Hoʻololi hoʻololi kala i nā mea holoi me ka hoʻohana ʻana iā PVP K15, K17 & K30 a me / a i ʻole kāna huahana wai i ka mea mahuka paʻakikī.
* ʻO ka wehe ʻana i ka waihoʻoluʻu lole a me ka mālama ʻana i ka helu ma o ka compexation a me ka dispersion me PVP K30 a me / a i ʻole kāna huahana wai.
* Nā mea holoi holoi holoi kahi e hoʻopau ai ʻo PVP K30 i ka hana hou ʻana o ka lepo.
* Emulsion polymerization kahi o ka PVP K30 a i ʻole a i ʻole kāna huahana hopena hopena wai paʻa, e hana nei ma ke ʻano he colloid pale, kōkua i ka redispersion o kahi 'broken'latex hoʻopau hoʻohana hoʻohana.
* Hoʻolahalaha e hoʻohana ana iā PVPK30 & K90 a me / a i ʻole kāna huahana wai no nona ka wai kala a me nā ʻōnaehana hoʻoiho pepa kākau e pili ana i nā pigment.
* Hollow pulupulu membrane hana kahi a PVP K90 & K30 a me / a i ʻole kāna huahana wai e hana ai i kahi mau hydrophilic domains i nā membrane polysulfone.
* I ka ʻaila i waiho ʻia i ka sima, kahi o PVP K30 & K90 a i ʻole kāna huahana wai e like me nā mea mālama kahe wai.
* Ma nā papa lithographic e hoʻohana ana i nā inika hydrophobic, kahi e hāʻawi ai ʻo PVPK15 i ka hoʻomaikaʻi ʻana i ka wahi nonimage.
* PVP K80, K85 & K90 a me / a i ʻole nā huahana wai i nā lāʻau lina stearate no ka hana noʻeau a me nā hana hana.
* I ke aniani aniani puluniu, e hoʻohana ana i ka PVP K30 & K90 a me / a i ʻole kāna huahana wai e hoʻoulu ai i ka hana e hāpai i ka lina polyivnylacetate.
* E like me nā mea hoʻolauleʻa pālolo i puhi ʻia, e hoʻohana ana iā PVP K30 & K90 a me / a i ʻole kāna huahana wai e hoʻonui ai i ka ikaika ʻōmaʻomaʻo.
* ʻO ka PVP K15, K17, K30, K60 & K90 a me / a i ʻole nā huahana wai i hoʻohana ʻia i ka mahiʻai ma ke ʻano he mea hoʻopaʻa a me ka mea hoʻoliʻiliʻi no ka pale ʻana i nā hua, ke kiʻi ʻoniʻoni ʻo mua ma ka mālama ʻana i nā hua a me nā uhi.
