1. Hiki ke hoʻoheheʻe ʻia ke hoʻomehana ʻia ma luna o 200 ° C, a ʻo ka lehu ma kahi o 0.5% ke puhi ʻia, a ʻaʻohe mea ma hope o ka hana ʻana i kahi slurry me ka wai. No kona viscosity, pili ia i kona degere o ka polymerization.
2. Hoʻohālikelike ka hoʻoheheʻe ʻana i ka wai i ka mahana, ʻoi aku ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa.
3. Hiki ke hoʻoheheʻe ʻia i ka hui ʻana o ka wai a me nā mea hoʻoheheʻe kūlohelohe e like me ka methanol, ethanol, ethylene glycol, glycerin a me acetone.
4. Ke noho ka paʻakai metala a i ʻole ka mea electrolyte i loko o kāna ʻano wai, hiki ke kūpaʻa ka hopena. Ke hoʻohui ʻia ka electrolyte i ka nui, e ʻike ʻia ka gel a i ʻole ka ua.
5. Hana ʻili. Loaʻa i kāna mau molela nā pūʻulu hydrophilic a me nā pūʻulu hydrophobic, i loaʻa ka emulsification, pale colloid a me ka pae paʻa.
6. ʻO ka wai wela. Ke piʻi ka wai wai i kahi wela (ma luna o ka mahana gel), e lilo ia i ʻeleʻele a hiki i ka gels a i ʻole ka hoʻoheheʻe ʻana, e lilo ka hopena i kona viscosity, akā hiki iā ia ke hoʻi i kona kūlana mua ma ka hoʻolili ʻana. ʻO ka mahana i loaʻa ai ka gelation a me ka ua ma muli o ke ʻano o ka huahana, ke ʻano o ka hopena a me ka wikiwiki o ka hoʻomehana.
7. Paʻa ka waiwai pH. ʻAʻole maʻalahi ka viscosity i ka wai e ka waikawa a me ka alkali. Ma hope o ka hoʻohui ʻana i kahi nui o ka alkali, ʻaʻohe mea wela kiʻekiʻe a haʻahaʻa haʻahaʻa paha, ʻaʻole ia e hoʻoheheʻe ʻia a i ʻole ka hoʻokaʻawale kaulahao.
8. Hiki i ka hoʻonā ke hana i kahi kiʻiʻoniʻoni māmā, paʻakikī a elastic ma ka ʻili ma hope o ka maloʻo ʻana. Hiki iā ia ke pale i nā mea hoʻoheheʻe organik, nā momona a me nā ʻaila like ʻole. ʻAʻole e melemele ke ʻike ʻia i ka mālamalama, ʻaʻole e ʻike ʻia nā māwae huluhulu. Hiki ke hoʻoheheʻe hou ʻia i ka wai. Inā hoʻohui ʻia ka formaldehyde i ka hopena a i ʻole ma hope o ka mālama ʻia ʻana me ka formaldehyde, ʻaʻole hiki ke hoʻoheheʻe ʻia ke kiʻiʻoniʻoni i loko o ka wai akā e pehu hapa.
9. Mānoanoa. Hiki iā ia ke mānoanoa i ka wai a me nā ʻōnaehana wai ʻole, a he hana anti-sag maikaʻi.
10. Hoʻonui i ka viscosity. Loaʻa i kāna mea hoʻonā wai i ka ikaika cohesive ikaika, hiki ke hoʻomaikaʻi i ka ikaika cohesive o ka cement, gypsum, pena, pigment, wallpaper a me nā mea ʻē aʻe.
11. Maikaʻi ʻia. Hiki ke hoʻohana ʻia e hoʻomalu i ka coagulation a me ka ua o nā ʻāpana paʻa.
12. Colloid pale e hoʻonui i kona kūpaʻa. Hiki iā ia ke pale i ka hoʻohui a me ka coagulation o nā droplets a me nā puaʻa, a pale pono i ka ua.
