KE KAKAU ANA I KA PONO O KA PAA WAI HPMC

1. ʻO ke ʻano o ka HPMC, a me kāna hana hoʻopaʻa wai e pili pono i ka nui i hoʻohui ʻia. ʻO ka nui o ka HPMC i hoʻohana ʻia i nā mea kūkulu hale ma ka mākeke e like me ka maikaʻi. Hoʻohui maʻamau ia e like me ka hoʻopaʻa ʻana, plastering, anti-cracking mortar, etc. ʻO ka nui o ka hoʻohui nui ʻo 2 ~ 2.5 KG / MT, ʻo ka nui o ka putty a me nā mea ʻē aʻe 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 tile grout ʻo 0.3 ~ 1 KG / MT nā ʻano hana like ʻole, e like me nā ʻano hana like ʻole. ʻO ka mortar self-leveling 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, ʻoi aku ka nui o ka HPMC, ʻoi aku ka maikaʻi o ka hana mālama 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 mortar sima a me nā huahana gypsum. I nā kau like ʻole a me nā ʻāpana like ʻole, e ʻokoʻa ka nui o ka mālama ʻana o ka wai o ka huahana like, akā ma ke ʻano nui, He mana nui ka Temperature i ka nui o ka mālama ʻana i ka wai, no laila aia kahi manaʻo ma ka mākeke: HPMC me ke kiʻekiʻe o ka gel wela he huahana kiʻekiʻe me ka nui o ka mālama ʻana i ka wai.

3. ʻO ka hana hana a me ka viscosity o ka cellulose ether -HPMC. Hoʻokaʻawale ʻia nā pūʻulu methoxy a me hydroxypropoxy ma ke kaulahao mole cellulose, hiki ke hoʻonui i ka hui ʻana o nā atomo oxygen ma ka hydroxyl a me ka ether bonds me ka wai. ʻO ka hiki ke hoʻopaʻa ʻana i ka hydrogen e lilo ka wai manuahi i wai paʻa, a laila e hoʻomalu pono i ka hoʻoheheʻe ʻana o ka wai a loaʻa ka paʻa wai kiʻekiʻe.
