Hoʻomohala ʻana i ka Rheological Thickener

ʻO ka hoʻomohala ʻana i nā mānoanoa rheological he mea nui i ka mōʻaukala o ka ʻepekema waiwai a me ka ʻenekinia. ʻO nā mea mānoanoa Rheological nā mea e hiki ai ke hoʻonui i ka viscosity a / a i ʻole ke kāohi i nā waiwai kahe o nā wai, nā hoʻokuʻu, a me nā emulsion.

Ua ʻike ʻole ʻia ka mānoanoa rheological mua i ke kenekulia 19, i ka wā i waiho ʻia ai ka hui ʻana o ka wai a me ka palaoa e kū no kekahi manawa, e loaʻa ana i kahi mea mānoanoa e like me ka gel. Ua ʻike ʻia kēia hui ʻana he mea hoʻokuʻu maʻalahi o nā ʻāpana palaoa i loko o ka wai, hiki ke hoʻohana ʻia ma ke ʻano he mānoanoa i nā noi like ʻole.

I ka hoʻomaka ʻana o ke kenekulia 20, ua ʻike ʻia nā mea ʻē aʻe he mau mea mānoanoa, e like me ka starch, gums, a me ka pālolo. Ua hoʻohana ʻia kēia mau mea ma ke ʻano he rheological mānoanoa i nā ʻano hana like ʻole, mai ka meaʻai a me nā mea hoʻonaninani i nā pena a me nā wai wili.

Eia nō naʻe, ua kaupalena ʻia kēia mau mānoanoa kūlohelohe, e like me ka hoʻololi ʻana i ka hana, ka naʻau i nā kūlana hoʻoponopono, a me ka hoʻohaumia microbiological. Ua alakaʻi kēia i ka hoʻomohala ʻana i nā mea mānoanoa rheological synthetic, e like me cellulose ethers, acrylic polymers, a me polyurethanes.

ʻO nā cellulose ethers, e like me ka sodium carboxymethyl cellulose (CMC), methyl cellulose (MC), a me ka hydroxypropyl cellulose (HPC), ua lilo i hoʻokahi o nā rheological thickeners i hoʻohana nui ʻia i nā noi like ʻole, ma muli o kā lākou mau waiwai kūʻokoʻa, e like me ka solubility wai, ʻO ke kūpaʻa pH, ka ʻike ikaika ionic, a me ka hiki ke hana kiʻiʻoniʻoni.

ʻO ka hoʻomohala ʻana i nā mānoanoa rheological synthetic i hiki ke hoʻokumu i nā huahana me ka hana mau, hoʻomaikaʻi i ke kūpaʻa, a me ka hana hoʻonui. Me ka piʻi nui ʻana o nā mea hana kiʻekiʻe, ke manaʻo nei e hoʻomau ka hoʻomohala ʻana o nā rheological thickeners hou, e alakaʻi ʻia e nā holomua o ka ʻepekema waiwai, kemika, a me ka ʻenekinia.
