Hoʻohana nui ʻia nā mea hana gypsum i nā hana kūkulu no ko lākou ikaika, lōʻihi a me ke ahi.Hana ʻia kēia mau mea me ka gypsum, kahi hui mineral i loaʻa mau i nā pōhaku sedimentary, a me ka wai.Hoʻohana pinepine ʻia nā mea hana gypsum no nā paia, nā kaupaku a me nā papahele ma nā hale noho, nā hale kūʻai a me nā hale ʻoihana.
ʻO ka Hydroxypropyl methylcellulose (HPMC) a me ka hydroxyethyl methylcellulose (HEMC) he mau nonionic cellulose eter i hoʻohana mau ʻia i nā hana kūkulu.Lawe ʻia lākou mai nā polymers kūlohelohe a he polymers hiki ke hoʻoheheʻe wai.Loaʻa iā lākou nā waiwai he mea kūpono ia no nā mea gypsum.
E ʻimi kēia ʻatikala i nā pono he nui o ka hoʻohana ʻana i ka HPMC a me HEMC i nā mea gypsum-based.
1. E hoʻomaikaʻi i ka hana
ʻO kekahi o nā pono nui o ka hoʻohana ʻana i ka HPMC a me ka HEMC i nā mea gypsum-based ʻo ko lākou hiki ke hoʻomaikaʻi i ka machinability.Ke hoʻohui ʻia kēia mau cellulose ethers i ka hui ʻana, hoʻonui lākou i ka mana paʻa wai o ka sima a hoʻomaikaʻi i ka hui ʻana, hoʻolaha a me ka troweling.
ʻO ka hopena, ua maʻalahi ka hana ʻana i nā mea hana gypsum a hiki i nā mea kūkulu hale ke hui maʻalahi, hoʻopili a hoʻohālikelike iā lākou i nā kikoʻī i makemake ʻia.He mea koʻikoʻi kēia waiwai no nā papahana e koi ana i nā hoʻolālā paʻakikī a i ʻole nā hiʻohiʻona paʻakikī.
Hoʻohui ʻia, hoʻomaikaʻi ʻia ke kūkulu ʻana e hoʻomaʻamaʻa i kahi kaʻina hana wikiwiki, e mālama i nā ʻaelike a me nā mea kūʻai aku i ka manawa a me ke kālā.
2. Hoʻonui i ka pili a me ka hoʻopili
ʻO kekahi pono koʻikoʻi o ka hoʻohana ʻana i ka HPMC a me ka HEMC i nā mea gypsum-based ʻo ko lākou hiki ke hoʻonui i ka paʻa a me ka pili.Hoʻomaikaʻi kēia mau cellulose ethers i ka pilina ma waena o ka hui a me ka substrate, e hopena i kahi paʻa ikaika a lōʻihi.
He mea maikaʻi loa kēia waiwai no nā papahana e pili ana i nā wahi haʻahaʻa kiʻekiʻe, e like me nā lumi ʻauʻau, lumi kuke a i ʻole nā loko ʻauʻau.ʻO ka hoʻonui ʻia ʻana o ka hoʻopaʻa ʻana a me ka hoʻopaʻa ʻana e pale aku i nā mea mai ka haki ʻana, ka ʻili a i ʻole ka delaminating, ʻoiai ma lalo o nā kūlana paʻakikī.
3. Hoʻonui i ka pale wai
Ua ʻike ʻia ʻo HPMC a me HEMC no ko lākou hiki ke hoʻomaikaʻi i ka pale wai.Ke hoʻohui ʻia i nā mea gypsum-based, ua hana kēia mau cellulose ethers i kahi pale pale a puni nā ʻāpana, e pale ana i ka wai mai ke komo ʻana i ka ʻili.
He mea koʻikoʻi kēia hiʻohiʻona no nā papahana e koi ana i ke kūpaʻa wai kiʻekiʻe, e like me nā basements, nā kumu a i ʻole nā facades.ʻO ka hoʻonui ʻia ʻana o ka wai e hōʻemi i ka pōʻino mai ka makū, ka ʻōpala a i ʻole ka maʻi, e hoʻolōʻihi i ke ola o ka hale.
4. Rheology maikaʻi loa
ʻO Rheology ka ʻepekema e aʻo i ka deformation a me ke kahe ʻana o nā mea ma lalo o ke kaumaha.ʻIke ʻia ʻo HPMC a me HEMC no kā lākou rheology maikaʻi loa, ʻo ia ka mea hiki iā lākou ke hoʻololi i ka viscosity, elasticity a me ka plasticity o nā mea gypsum-based.
He mea maikaʻi loa kēia hiʻohiʻona no nā papahana e koi ana i nā pae like ʻole o ke kūlike, e like me nā papahele hoʻonaʻauao ponoʻī, pena hoʻonaninani a i ʻole nā moldings.Hiki i ka rheology maikaʻi ke hoʻololi i nā mea i nā ʻano like ʻole, ka nui a me nā ʻano like ʻole, e hopena i kahi ʻili laulima, ʻano like ʻole.
5. Hoʻonui i ka ea entrainment
ʻO ka Aeration ke kaʻina hana o ka hoʻokomo ʻana i nā ʻōhū ea liʻiliʻi i loko o ka hui ʻana e hoʻomaikaʻi i ke kūpaʻa manuahi-thaw o ka mea, ka hana a me ka lōʻihi.ʻO HPMC a me HEMC he mau mea hoʻoheheʻe ea maikaʻi loa, ʻo ia hoʻi, hoʻonui lākou i ka helu a me ka nui o nā ʻōpū o ka ea i nā mea gypsum.
He mea pono loa kēia hiʻohiʻona no nā papahana e koi ana i ke kūpaʻa kiʻekiʻe o ka hoʻoheheʻe ʻana i ka hau, e like me nā paepae waho, nā alahaka a i ʻole nā tunnels.ʻO ka hoʻonui ʻia ʻana o ka ea e pale aku i nā mea mai ka haki ʻana, ka ʻili ʻana a i ʻole ka pōʻino ma muli o ka hoʻololi ʻana o ka mahana, e hōʻemi ana i nā kumukūʻai mālama a me ka hoʻomaikaʻi ʻana i ka palekana o ka hale.
i ka hopena:
ʻO ka hoʻohana ʻana o HPMC a me HEMC i nā mea gypsum-based he nui nā pono no ka ʻoihana kūkulu.ʻO kēia mau nonionic cellulose ethers e hoʻomaikaʻi i ke kaʻina hana, hoʻonui i ka adhesion a me ka hoʻopili ʻana, hoʻonui i ka pale wai, hāʻawi i ka rheology maikaʻi loa a hoʻomaikaʻi i ka ea.
ʻAʻole kēia mau hiʻohiʻona e hoʻomaikaʻi wale i ka maikaʻi o ke kūkulu ʻana, akā e hōʻemi hoʻi i nā kumukūʻai, hoʻonui i ka huahana, a hoʻonui i ka palekana o nā limahana hana a me nā mea hoʻohana.No laila, hiki i ka hoʻohana ʻana o HPMC a me HEMC i nā mea gypsum-based ke koho maikaʻi a noʻonoʻo no kekahi papahana kūkulu.
