1. Manoanoa anoano
ʻO ka mea maʻamau ka bentonite organik, nona ka mea nui he montmorillonite.Hiki i kāna hana kūikawā lamellar ke hāʻawi i ka uhi me ka pseudoplasticity ikaika, thixotropy, paʻa paʻa a me ka lubricity.ʻO ke kumumanaʻo o ka mānoanoa ʻo ia ka pauka e hoʻomoʻa i ka wai a pehu i ka mānoanoa o ka wai, no laila aia kahi paʻa wai.
ʻO nā hemahema: ʻaʻole i maʻalahi ke kahe a me ka pae ʻana i ka hana, ʻaʻole maʻalahi e hoʻopuehu a hoʻohui.
2. Cellulose
ʻO ka hydroxyethyl cellulose ka mea i hoʻohana pinepine ʻia.HEC), nona ka pono mānoanoa kiʻekiʻe, ka hoʻokuʻu maikaʻi, ka hoʻopuehu a me nā waiwai paʻa wai, ka mea nui no ka mānoanoa o ka pae wai.
ʻO nā mea pōʻino: pili i ka pale wai o ka uhi ʻana, lawa ʻole ka hana anti-mold, a me ka hana pae maikaʻi ʻole.
3. ʻAlika
Hoʻokaʻawale ʻia nā mānoanoa Acrylic i ʻelua ʻano: acrylic alkali-swellable thickeners (ASE) a me associative alkali-swellable thickeners (HASE).
ʻO ke kumu mānoanoa o ka waikawa acrylic alkali-swellable thickener (ASE) e hoʻokaʻawale i ka carboxylate ke hoʻololi ʻia ka pH i ka alkaline, no laila e hoʻonui ʻia ke kaulahao mole mai kahi helical i kahi koʻokoʻo ma o ka isotropic electrostatic repulsion ma waena o nā ion carboxylate, e hoʻomaikaʻi i ka ʻO ka viscosity o ka pae wai.Loaʻa i kēia ʻano mānoanoa ka hana mānoanoa kiʻekiʻe, pseudoplasticity ikaika a me ka hoʻokuʻu maikaʻi.
Hoʻopuka ka hui ʻana o ka alkali-swellable thickener (HASE) i nā pūʻulu hydrophobic ma ke kumu o nā mānoanoa alkali-swellable mānoanoa (ASE).Pēlā nō, ke hoʻololi ʻia ka pH i ka alkaline, ʻo ka repulsion electrostatic like-sex ma waena o nā ion carboxylate e hoʻonui ʻia ke kaulahao molekala mai ke ʻano helical a hiki i ke ʻano koʻokoʻo, e hoʻonui ai i ka viscosity o ka pae wai;a hiki i nā hui hydrophobic i hoʻokomo ʻia ma ke kaulahao nui ke hui pū me nā ʻāpana latex e hoʻonui i ka viscosity o ka pae emulsion.
ʻO nā hemahema: ʻoluʻolu i ka pH, lawa ʻole ka kahe ʻana a me ka pae ʻana o ke kiʻi pena, maʻalahi e mānoanoa ma hope.
4. Polyurethane
ʻO ka polyurethane associative thickener (HEUR) he polymer hoʻoheheʻe wai ethoxylated polyurethane i hoʻololi ʻia i ka hydrophobically, nona ka mānoanoa hui non-ionic.Aia ʻekolu ʻāpana: base hydrophobic, chain hydrophilic a me base polyurethane.Hoʻonui ka waihona polyurethane i ka hopena pena, a paʻa ke kaulahao hydrophilic i ka pae wai.Hoʻopili ke kumu hydrophobic me nā hale hydrophobic e like me nā ʻāpana latex, surfactants, a me nā puaʻa., ka hana ʻana i ʻekolu-dimensional network structure, i mea e hoʻokō ai i ke kumu o ka mānoanoa.
Hoʻohālikelike ʻia ia e ka mānoanoa o ka pae emulsion, kahe maikaʻi a me ka hoʻokō ʻana i ka pae, ʻoi aku ka maikaʻi o ka mānoanoa a me ka mālama ʻana i ka viscosity paʻa, ʻaʻohe palena pH;a loaʻa iā ia nā pōmaikaʻi i ka pale ʻana i ka wai, gloss, transparency, etc.
ʻO nā mea pōʻino: i loko o ka ʻōnaehana viscosity a me ka haʻahaʻa haʻahaʻa, ʻaʻole maikaʻi ka hopena anti-settling ma ka pauka, a ua maʻalahi ka hopena mānoanoa e nā dispersants a me nā solvents.
