ʻO ka pauka calcium lehu, ka pauka calcium kaumaha (a i ʻole ka pauka gypsum), a ʻo ka cellulose nā mea nui e hana ai i ka pauda putty.
ʻO ka hana o ka lehu calcium pauka i ka putty ka hoʻomaikaʻi ʻana i ka hana o ka huahana, me ka hoʻomaikaʻi ʻana i ka ikaika, ka paʻakikī, ka pale ʻana i ka wai o ka huahana putty pauka, a me ka hana ʻana o ka ʻōpala a me ka wili ʻana i ka wā o ke kūkulu ʻana.Hoʻohana ʻia ka pauka calcium koʻikoʻi ma ke ʻano he mea hoʻopiha e hōʻemi i nā kumukūʻai hana, a he kuleana ko cellulose i ka mālama ʻana i ka wai., hoʻopaʻa ʻana a me nā hana ʻē aʻe.
I ke kūkulu ʻia ʻana o ka pauka putty, ʻo ka huʻihuʻi kahi pilikia maʻamau.He aha ke kumu?
ʻO ka pauka calcium lehu (ʻo ka mea nui ka calcium hydroxide, kahi huahana i hoʻomaʻemaʻe ʻia o ka lime), ka pauka calcium kaumaha (ʻo ka mea nui ka calcium carbonate, ʻo ia ka pauka pōhaku calcium carbonate i hoʻoheheʻe ʻia mai ka pōhaku calcium carbonate) maʻamau ʻaʻole ia e hoʻoulu i ka pauka putty. e pohā ma hope o ka hoʻohana ʻana.ʻōhū pōʻino.
kumu o ka pehu
ʻO nā kumu nui o ka huʻa ʻana o ka pauka putty penei:
1. He oolea loa ka papa kumu me na puka liilii.I ka ʻoki ʻana, hoʻopaʻa ka putty i ka ea i loko o ka lua, a laila hoʻihoʻi ke kaomi ea e hana i nā ʻōpū ea.
2. He mānoanoa loa ka ʻōpala hoʻokahi-pass, a ʻaʻole ʻoki ʻia ka ea i loko o nā pores o ka putty.
3. Ua maloʻo loa ka papa kumu a ʻoi aku ka kiʻekiʻe o ka lawe ʻana i ka wai, kahi e maʻalahi ai ka hoʻoulu ʻana o ka ea ma ka ʻili o ka putty.
4. ʻO ka pena wai-kūʻai, ke kiʻekiʻe kiʻekiʻe a me nā ʻili kumu ʻē aʻe me ka paʻa maikaʻi o ka ea e hoʻohūhū ai.
5. He mea maʻalahi ka Putty i nā ʻōhū i ka wā kūkulu wela kiʻekiʻe.
6. He haʻahaʻa loa ka ʻai ʻana o ka wai o ka mea kumu, e alakaʻi ana i ka lōʻihi o ka mālama ʻana i ka wai o ka putty i ka wā i ʻoki ʻia, no laila e noho lōʻihi ka putty i ke ʻano o ka slurry ma ka paia no ka manawa lōʻihi. maloʻo, no laila ʻaʻole maʻalahi ka ʻūhū ʻana o ka ea e ka trowel, e hopena i nā pinholes ʻO nā pores ke kumu i ʻoi aku ai ka nui o nā ea ma luna o ka formwork i ʻoki ʻia ma mua o ka paia i ka ʻenekinia.Nui ka wai o ka pā, akā ʻoi loa ka haʻahaʻa o ka wai o ka formwork top.
7. He kiʻekiʻe loa ka viscosity o cellulose.
