paʻakai alginate

paʻakai alginate, also known as seaweed glue, is a white or light yellow particle or powder, almost odorless and tasteless. It is a high viscosity polymer compound and a typical hydrophilic sol. It is widely used in many industries such as food, medicine, printing and dyeing because of its stability, thickening and emulsification, hydration and gelation.

I ka ʻoihana paʻi a me ka pena ʻana, hoʻohana ʻia ka sodium alginate e like me ka paʻi dye reactive, ʻoi aku ka maikaʻi ma mua o ka palaoa, starch a me nā nui ʻē aʻe. ʻO nā lole uila i paʻi ʻia, nā ʻōlinolino, nā laina mōakāka, ka hāʻawi ʻana i ke kala kiʻekiʻe, ke kala kūlike, a me ka maikaʻi permeability a me ka plasticity. ʻO ka limu limu ke kāʻei ʻoi loa o ka ʻoihana paʻi a me ka hana kala. Ua hoʻohana ākea ʻia ia i ka paʻi ʻana o ka pulupulu, ka hulu hipa, ka siliki, ka nylon a me nā lole ʻē aʻe, keu hoʻi i ka hoʻomākaukau ʻana o ka paʻi paʻi pad. Hiki iā ia ke hoʻohana ʻia me he mea lāsi maʻawe loloa, ka mea hiki ʻole ke mālama i ka nui o ka palaoa, akā hoʻolilo i ka maʻawe maʻawe lint me ke kaʻawale, kūpale kūpale a hoʻemi i ka helu haki hopena, i mea e hoʻomaikaʻi ai i ka ulana ulana ʻana, pono no nā ʻelua pulupulu a me ka pulupulu synthetic.
