Papa Hana Hale （HPMC ）Hydroxypropyl methyl cellulose
Ua lilo nā mortar i hui ʻia i mea koʻikoʻi o ka ʻoihana mortar ma Global a pāʻani i ka hana aninondispensable ma muli o ka hoʻolaha ʻana o ka mākeke a me ke kākoʻo aupuni o ke kulekele.I ka hoʻomohala ʻana i nā morta, he mea nui ka cellulose ether.
ʻO ka mortar maʻamau ke koi aku nei i kahi liʻiliʻi o ka sima, akā ʻoi aku ka kiʻekiʻe o nā koi no kāna hana a me ka mīkini hoʻoheheʻe ʻana i nā waiwai, no laila he mea nui ka hoʻonui ʻana i ke one a me nā mea hoʻohui.Eia kekahi, e lilo ana ka noi mechanical i mea maʻamau o ka hoʻomohala ʻana i ka mortar i hoʻomākaukau ʻia, cellulose ether e hana i ka hana mechanical.
Nā hiʻohiʻona huahana
E hoʻonui i ka makemake wai.
Ka paʻa wai kiʻekiʻe, hoʻolōʻihi i ka manawa hana o ka mea, hoʻomaikaʻi i ka hana hana, pale i ka hanana o ka crusting, a kōkua i ka hoʻomaikaʻi ʻana i ka ikaika mechanical o ka mea.
Hoʻomaikaʻi i ka hana hana, hāʻawi i ka lubrication a me ke ʻano like ʻole, i maʻalahi ka holoi ʻana i ka ʻili o ka mea, pēlā e hoʻomaikaʻi ai i ka hana ʻana, a hoʻomaikaʻi i ke kūʻē ʻana i ka haki ʻana o ka putty.
E hoʻomaikaʻi i ka homogeneity, a hoʻomaikaʻi i ke kūpaʻa kahe ʻana.
HPMC no ka hoʻopili tile
Loaʻa ka hana kiʻekiʻe a me ka hana maikaʻi o nā tile ceramic i ka wā i hoʻopili ʻia ma nā substrate like ʻole.ʻO ka pale ʻana i ka skid a me ka manawa wehe maikaʻi ke kī i nā koi adhesive maikaʻi aʻe.
HPMC no ka paʻi pā
ʻO ka HPMC he cellulose ether non-ionic i hana ʻia mai ka pulupulu pulupulu maoli ma lalo o ke kaʻina hana kemika.He mea ʻala ʻole, ʻono ʻole a me ka pauka keʻokeʻo ʻole, hiki ke hoʻoheheʻe ʻia i loko o ka wai maʻamau e hana i kahi hopena viscous māmā me nā waiwai o ka mānoanoa, hoʻopaʻa, hoʻopuehu, emulsifying, uhi kiʻiʻoniʻoni, hoʻopaneʻe, hoʻopaʻa ʻana, gelling, mālama wai a me ka pale colloid.
Hāʻawi nā cellulose ethers i kēia mau waiwai maikaʻi i ka mortar:
一Ka hiki ke hoʻomaʻemaʻe i ka substrate
一 Hiki ke hoʻopaʻa wai kiʻekiʻe
一 maikaʻi ka pipiʻi ʻana a me ka hana ʻana i ka paila
一 Hoʻomaikaʻi i ka hydration sima ma ka ikaika hoʻopaʻa
Hōʻike huahana
1) Nānā: ʻO ka HPMC he cellulose ether nonionic, keʻokeʻo keʻokeʻo keʻokeʻo keʻokeʻo a i ʻole granule, ʻono ʻole a ʻono ʻole, hiki ke hoʻoheheʻe ʻia i ka wai anuanu, glacial acetic acid, ethanol, methanol a me propylene glycol, hiki ke hoʻoheheʻe ʻia i ka acetone ma muli o ke ʻano o nā pani. ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai wela, ethylene glycol a me toluene.Hoʻoheheʻe ʻia ka HPMC i loko o kahi hui ʻana o 10% methanol a me 90% methylene chloride e hana i nā hopena colloidal.
2) Loaʻa i ka hopena o HPMC ka hana ma luna, ke aniani kiʻekiʻe, a me ka hana paʻa.Ke hoʻomehana ʻia i kekahi mahana, lilo ka hopena i ʻeleʻele a i ʻole he gel flocculent.Eia nō naʻe, akaka hou ka hopena ma hope o ka hoʻomaloʻo ʻana.Loaʻa i nā ʻano like ʻole o ka HPMC nā mahana gelation like ʻole.ʻOkoʻa ka solubility me ka viscosity.ʻO ka haʻahaʻa o ka viscosity, ʻoi aku ka kiʻekiʻe o ka solubility.ʻOkoʻa nā ʻano like ʻole o ka HPMC i kekahi mau waiwai a ʻaʻole pili ka pH i ko lākou solubility i ka wai.
3) Ka nui o nā ʻāpana: 100% ka nui o ka hala ma 80 mesh.
4) ʻIke ʻia ka haʻahaʻa: 0.25-0.70 g/mL (maʻamau ma kahi o 0.5 g/mL), 1.26-1.31mL kikoʻī.
5) Ka wela hoʻololi kala: 190-200 ° C;ʻO ka mahana carbonization: 280-300 ° C.
6) Kūleʻa o ka ʻili: 42-56 dyn/cm (2% aqueous solution).
7) ʻO ka maʻiʻo methoxy kiʻekiʻe ma HPMC, ka haʻahaʻa haʻahaʻa o ka gelation, a me ke kiʻekiʻe o ka solubility i ka wai a me ka hana ma luna.
8) Loaʻa i ka HPMC kekahi mau hiʻohiʻona ʻē aʻe, no ka laʻana, ka waiwai mānoanoa, ka paʻa pH, ka paʻa ʻana o ka wai, ka waiwai kiʻiʻoniʻoni maikaʻi loa, ka hoʻopuehu maikaʻi a me ka hiki ke hoʻopili.
