He aha ke ʻano o ka mānoanoa i hoʻohana ʻia i ka pena?

ʻO ka mānoanoa i hoʻohana ʻia i ka pena he mea maʻamau ia e hoʻonui ai i ka viscosity a i ʻole ka mānoanoa o ka pena me ka ʻole o ka hoʻopili ʻana i kāna mau waiwai ʻē aʻe e like me ke kala a me ka manawa maloʻo. ʻO kekahi o nā ʻano mānoanoa maʻamau i hoʻohana ʻia i ka pena he rheology modifier. Hana kēia mau mea hoʻololi ma ka hoʻololi ʻana i ke ʻano kahe o ka pena, e ʻoi aku ka mānoanoa a me ka paʻa.

Nui nā ʻano mea hoʻololi rheology i hoʻohana ʻia i loko o nā hoʻolālā pena, ʻo kēlā me kēia me kona ʻano ponoʻī a me nā pono ponoʻī. ʻO kekahi o nā mea hoʻololi rheology i hoʻohana pinepine ʻia:

Nā mea i loaʻa iā Cellulose:
Hydroxyethyl cellulose (HEC)
Hydroxypropyl cellulose (HPC)
Methyl cellulose (MC)
Ethyl hydroxyethyl cellulose (EHEC)
Nā mea mānoanoa hui:
Urethane ethoxylated hydrophobically i hoʻololi ʻia (HEUR)
ʻO ka emulsion alkali-soluble hydrophobically i hoʻololi ʻia (HASE)
Hydrophobically modified hydroxyethyl cellulose (HMHEC)
Nā mea i loaʻa mai ka Polyacrylic Acid Derivatives:
Carbomer
ʻO nā copolymers ʻakilika
Pālolo Bentonite:
ʻO ka pālolo Bentonite kahi mānoanoa maoli i loaʻa mai ka lehu pele. Hana ia ma ka hana ʻana i ka ʻupena o nā ʻāpana e paʻa i nā molekala wai, a laila e mānoanoa ai ka pena.
Silica Gel:
ʻO ka silica gel kahi mānoanoa synthetic e hana ana ma ka hoʻopaʻa ʻana a me ka hoʻopaʻa ʻana i ka wai i loko o kona ʻano porous, no laila e mānoanoa ai ka pena.
Polyurethane mānoanoa:
ʻO nā polyurethane mānoanoa he polymers synthetic hiki ke hoʻopili ʻia e hāʻawi i nā waiwai rheological kikoʻī i ka pena.
Xanthan Gum:
ʻO ka Xanthan gum kahi mānoanoa maoli i loaʻa mai ka fermentation o nā kō. Hana ia i ka like me ka gel ke hui pū ʻia me ka wai, kūpono ia no ka pena mānoanoa.
Hoʻohui pinepine ʻia kēia mau mea hoʻololi rheology i ka hoʻokumu ʻana i ka pena i ka wā o ka hana ʻana i ka nui kūpono e hoʻokō ai i ka viscosity makemake a me nā waiwai kahe. ʻO ke koho ʻana i ka mānoanoa e pili ana i nā ʻano like ʻole e like me ke ʻano o ka pena (e laʻa, ka wai a i ʻole ka solvent-based), ka viscosity i makemake ʻia, ke ʻano noi, a me nā noʻonoʻo kaiapuni.

Ma kahi o ka mānoanoa o ka pena, hana koʻikoʻi nā mea hoʻololi rheology i ka pale ʻana i ka sagging, hoʻomaikaʻi i ka brushability, hoʻonui i ka pae, a me ka hoʻomalu ʻana i ka spattering i ka wā o ka noi. ʻO ke koho o ka mānoanoa he mea nui i ka hoʻoholo ʻana i ka hana holoʻokoʻa a me nā hiʻohiʻona noi o ka pena.
