ʻO ka waiʻona Polyvinyl CAS: 25213-24-5

Loaʻa ka hoʻohana nui ʻia ʻana o ka Polyvinyl alcohol (PVA) ma nā ʻoihana like ʻole ma muli o kona mau waiwai kupaianaha. I loko o ka ʻoihana hoʻopili, lawelawe ia ma ke ʻano he mea nui i nā ʻano hana like ʻole, e hāʻawi ana i nā waiwai hoʻopili ikaika i nā noi mai nā kāpili lāʻau a i nā mea hoʻopili pepa. ʻO kona hiki ke hoʻoheheʻe ʻia i ka wai a me nā hiki ke hana ʻoniʻoni e lilo ia i mea nui loa i ka hana ʻana i nā mea hoʻopili wai-hoʻoheheʻe ʻia, nā ʻeke holoi lole, a me nā mea hana ana lole, e hāʻawi ana i nā hoʻonā no nā pono hoʻopili eco-friendly a me ka hoʻoheheʻe ʻia. I loko o ka ʻoihana lole, hoʻohana nui ʻia ka PVA ma ke ʻano he mea hana ana warp e hoʻomaikaʻi i ke kaʻina hana ulana, e hāʻawi ana i ka ikaika a me ka maʻalahi i nā olonā. Eia kekahi, hana ia ma ke ʻano he colloid pale i ka hana ʻana i nā copolymers vinyl acetate a ma ke ʻano he mea hoʻopaʻa i ka paʻi pigment. Eia kekahi, he kuleana koʻikoʻi ka PVA i ka ʻoihana pepa, kahi e hoʻohana ʻia ai ma ke ʻano he mea hana ana i ka ʻili e hoʻomaikaʻi i ka ikaika o ka pepa, ka paʻi ʻana, a me ka absorbency ʻīnika. Hoʻohana nā ʻoihana lāʻau lapaʻau a me nā meaʻai i ka PVA i ka hana ʻana i nā capsules, ma ke ʻano he mea uhi no nā papa, a i ka hana ʻana i nā kiʻiʻoniʻoni ʻai no ka hoʻopili meaʻai. ʻO kona biocompatibility a me kona ʻano ʻawaʻawa ʻole e hoʻolilo i ka PVA i mea waiwai nui i nā noi lapaʻau, me ke ʻano he ʻāpana i nā ʻaʻahu ʻeha, nā ʻōnaehana lawe lāʻau, a me nā scaffolds ʻenekinia ʻiʻo. Ma keʻano holoʻokoʻa, hōʻike nā noi like ʻole o PVA i kona koʻikoʻi ma ke ʻano he polymer versatile i nā ʻāpana ʻoihana a me nā ʻoihana like ʻole.
