Hoʻohana i ka Hydroxypropyl Methyl Cellulose i ka Gypsum Mortar

(1), na ano ohydroxypropyl methylcellulose i loko o ka gypsum mortar:

1. Hana maikaʻi i ka hana: he maʻalahi a maʻalahi ke kau ʻana, hiki ke hoʻoheheʻe ʻia i ka manawa hoʻokahi, a he plasticity i ka manawa like.

2. Paʻa ikaika: He kūpono ia no nā ʻano kumu gypsum a pau, a hiki ke hōʻemi i ka manawa o ka hāʻule ʻana o ka gypsum, hoʻemi i ka nui o ka hoʻomaloʻo ʻana, a ʻaʻole maʻalahi ka pā a hoʻoheheʻe.

3. Maikaʻi ka paʻa ʻana o ka wai: hiki iā ia ke hoʻolōʻihi i ka manawa hana o ka base gypsum, hoʻomaikaʻi i ke kūpaʻa mānoanoa o ke kumu gypsum, hoʻonui i ka ikaika hoʻopaʻa ma waena o ke kumu gypsum a me ka papa kumu, ka hana hoʻopaʻa pulu maikaʻi, a hoʻemi i ka lehu pae ʻana a me nā pilikia ʻē aʻe.

4. E hoʻomaikaʻi i ka laha hoʻolaha o ke kumu gypsum: Ke hoʻohālikelike ʻia me ka hydroxypropyl methylcellulose ether like, e hoʻonui nui ʻia ka pālahalaha. Hiki i nā huahana Hydroxypropyl methylcellulose ke hoʻonui i ka nui o ka uhi, hiki ke uhi i nā wahi hou aku, hiki ke hōʻemi i ka ikaika o ka hana, mālama i nā mea waiwai, a hoʻomaikaʻi i nā pono waiwai.

5. ʻO ka hana anti-sagging maikaʻi: i ka wā e kau ana i nā papa mānoanoa, ʻaʻole e sag ka hana hoʻokahi-pass, a ʻoi aku ma mua o ʻelua mau ala, ma luna o 3cm, ʻaʻole e sag i ke kau ʻana, a maikaʻi ka plasticity.

6. Nā kahua noi a me ke ʻano: ʻo ka gypsum plastering māmā, ʻo ka mea i ʻōlelo ʻia he 2.5-3.5 kg / ton.

(2) Ho'āʻo hoʻokolohua noi no ka hydroxypropyl methylcellulose:

1. Ka ho'āʻo ikaika: Ma hope o ka hoʻāʻo ʻana, ua loaʻa i ka hydroxypropyl methylcellulose gypsum-based hydroxypropyl methylcellulose ka ikaika hoʻopaʻa tensile maikaʻi a me ka ikaika compressive.

2. Ho'āʻo Anti-sagging: ʻAʻohe sag ke hoʻohana ʻia ka hana hoʻokahi-pass i nā papa mānoanoa, a ʻaʻohe sag ke noi ʻia no nā hala ʻelua (ma luna o 3cm), a maikaʻi ka plasticity.

3. ʻO ka hoʻāʻo ʻana i ka pā: he māmā a maʻalahi ke kau ʻana, a hiki ke hoʻoheheʻe ʻia i ka manawa hoʻokahi. He palupalu a palupalu ka ʻili, me ka ʻōlinolino.

4. Ka ho'āʻo pāhaʻi ʻana: ʻO ka pāhola ʻana o ke kumu gypsum e pili ana i ka hopena i loaʻa ma ke ana ʻana i ka mānoanoa nui o ka base gypsum. Hoʻokahi tona o nā huahana gypsum no ke kūkulu ʻana i kahi pā 10mm mānoanoa.

5. Ka ho'āʻoʻana o ka wai hoʻopaʻa wai: ʻOi aku ka nui o ka wai paʻa ʻana o ka gypsum ma mua a i ʻole like me 60%, a me 0.2% a me 0.25% o ka gypsum. Hoʻohui ʻia ka hydroxypropyl methylcellulose He hana paʻa wai maikaʻi.
