ʻO ka waiʻona polyvinyl (PVA) Shuangxin G
(polyvinyl alcohol · PVOH · PVA) ua hoʻohana nui ʻia e nā mea hoʻohana ma ka home a me nā ʻāina ʻē i ka hoʻohana ʻana i nā mea hana ʻenehana a me nā mea hana e like me ka binder, ka mea hoʻopili pepa, emulsifier, suspending agent, fiber a me ke kiʻiʻoniʻoni ma muli o kona solubility wai maikaʻi. adhesion, hana kiʻiʻoniʻoni a me ka paʻa kemika.
Mai ka makahiki 1927, me ka ʻenehana holomua a me ka noiʻi paʻa ʻole, ua hoʻomohala ʻia nā ʻano ʻano kūikawā he nui. Nui nā ʻano like ʻole i hana ʻia ma lalo o ka hoʻokele koʻikoʻi, a ʻo kā lākou ʻōnaehana maikaʻi e hoʻokō i ke kūlana honua o iso9001: 2015. Hoʻomaikaʻi nui ʻia nā huahana Grossinor ma ke ʻano he mea waiwai nui i nā ʻano ʻoihana like ʻole, e hāʻawi ana i ke kākoʻo ikaika no nā ʻenehana e hiki mai ana.
