KE KĀKĀKĀ NEI I KE KOʻIKOʻI O KA PAʻA ʻANA I KA WAI O HPMC

1. ʻO ka nui o ka HPMC, a me kāna hana paʻa wai e pili pono ana i ka nui i hoʻohui ʻia. ʻOkoʻa ka nui o ka HPMC i hoʻohana ʻia i nā mea kūkulu hale ma ka mākeke ma muli o ka maikaʻi. Hoʻohui pinepine ʻia ia i nā mea e like me ka hoʻopili ʻana, ka plastering, ka mortar anti-cracking, a pēlā aku. ʻO ka nui o ka hoʻohui maʻamau he 2 ~ 2.5 KG /MT, ʻo ka nui o ka putty a pēlā aku ma waena o 2 ~ 4.5 KG / MT, ʻo ke kāpili tile ma waena o 3.5 ~ 4 KG / MT, a ʻo ka nui o ka grout tile he 0.3 ~ 1 KG / MT e like me nā ʻano hana kūkulu like ʻole, ka laulā o ka hakahaka a me ka maikaʻi o ka slurry, ʻo ka mortar leveling ponoʻī ma waena o 0.2 ~ 0.6 KG / MT, a ʻo ka ETICS ma waena o 4 ~ 7 KG / MT. I loko o kēia pae, ʻo ka nui o ka HPMC i hoʻohui ʻia, ʻoi aku ka maikaʻi o ka hana paʻa wai.

2. Ka hopena o ke kaiapuni kūkulu. ʻO ka haʻahaʻa o ka ea, ka mahana, ke kaomi makani, ka wikiwiki o ka makani a me nā mea ʻē aʻe e hoʻopilikia i ka nui o ka volatilization o ka wai i loko o ka sima sima a me nā huahana gypsum. I nā kau like ʻole a me nā wahi like ʻole, e ʻokoʻa ka nui o ka paʻa ʻana o ka wai o ka huahana like, akā ma ke ʻano laulā, he mana nui ka mahana i ka nui o ka paʻa ʻana o ka wai, no laila aia kahi manaʻo ma ka mākeke: ʻO ka HPMC me ka mahana gel kiʻekiʻe he huahana kiʻekiʻe me ka nui o ka paʻa ʻana o ka wai.

3. Ke kaʻina hana a me ka mānoanoa o ka cellulose ether -HPMC. Hoʻolaha like ʻia nā hui methoxy a me hydroxypropoxy ma ke kaulahao molekala cellulose, hiki ke hoʻonui i ka hui pū ʻana o nā ʻātoma oxygen ma nā pilina hydroxyl a me ether me ka wai. ʻO ka hiki ke hoʻopaʻa hydrogen e hoʻolilo i ka wai manuahi i wai paʻa, no laila e kāohi pono ana i ka mahu ʻana o ka wai a hoʻokō i ka paʻa wai kiʻekiʻe.
