ʻO ka Hydroxypropylmethylcellulose (HPMC) he cellulose ether i loaʻa mai ka cellulose maoli. Hoʻohana ʻia ʻo HPMC i nā ʻano noi like ʻole me ka hana ʻana i ka meaʻai, ke kūkulu ʻana, nā lāʻau lapaʻau a me nā mea hoʻonaninani. Ma ke ʻano he mea hana HPMC, ua kūpaʻa mākou i ka hana ʻana i nā huahana kiʻekiʻe e kūpono i nā pono o kā mākou mea kūʻai.
I nā makahiki i hala iho nei, ua lilo ka HPMC haʻahaʻa haʻahaʻa i mea kaulana i ka ʻoihana kūkulu ma muli o kāna mau waiwai noi i hoʻomaikaʻi ʻia a me nā waiwai dispersion maikaʻi. Hoʻohana maʻamau ʻia ka HPMC haʻahaʻa haʻahaʻa i loko o nā mortar, plasters a me nā tile adhesives ma ke ʻano he mānoanoa, mea hoʻopaʻa a me ka mea mālama wai. Ma kēia ʻatikala, wehewehe mākou i ka HPMC viscosity haʻahaʻa a me kāna mau pono no ka ʻoihana kūkulu.
He aha ka HPMC viscosity haʻahaʻa?
ʻO ka HPMC haʻahaʻa haʻahaʻa he cellulose ether me ka haʻahaʻa haʻahaʻa i hoʻohālikelike ʻia me ka HPMC kuʻuna. ʻO kēia ka mea e maʻalahi ai ka lawelawe ʻana a me ka hāʻawi ʻana, a hoʻomaikaʻi pū i ka hana o ka mea kūkulu hale. Hoʻohana mau ʻia ka HPMC haʻahaʻa haʻahaʻa i ka mortar a me nā mea hana ʻē aʻe e hana ma ke ʻano he mānoanoa a hoʻomaikaʻi i ka hui ʻana o ka mea a me ka hana.
He aha nā pōmaikaʻi o ka HPMC viscosity haʻahaʻa?
Hoʻonui i ka hana: ʻO ka HPMC haʻahaʻa haʻahaʻa e hoʻomaikaʻi i ka hana o nā mea hana ma o ka hoʻomaikaʻi ʻana i ke kahe a me ka hoʻopuehu ʻana o ka mea. ʻO kēia ka maʻalahi o ka noi a hoʻomaikaʻi i ka maikaʻi holoʻokoʻa o ka huahana i hoʻopau ʻia.
ʻOi aku ka maikaʻi o ka hoʻopili ʻana: ʻO ka HPMC haʻahaʻa haʻahaʻa haʻahaʻa e hana ma ke ʻano he mea hoʻopili e hoʻomaikaʻi i ka pili ʻana o nā mea kūkulu hale i nā substrates. ʻO kēia ka mea hoʻohui kūpono no nā morta, plasters a me nā tile adhesives.
Hoʻomaikaʻi i ka paʻa wai: Hiki i ka HPMC haʻahaʻa haʻahaʻa ke hoʻonui i ka paʻa ʻana o ka wai i nā mea kūkulu hale, e hōʻemi ana i ka nui o ka wai e pono ai e hoʻokō i ka hana i makemake ʻia. Mālama kēia i nā kumukūʻai a hoʻomaikaʻi i ka hana huahana.
ʻAʻohe mea ʻawaʻawa a pili i ke kaiapuni: haʻahaʻa-viscosity HPMC ʻaʻohe mea ʻawaʻawa a pili kaiapuni, a he koho palekana no nā mea kūkulu hale. He biodegradable a hiki ke hana hou ia.
Ka laulā o nā noi: Hiki ke hoʻohana ʻia ka HPMC haʻahaʻa haʻahaʻa i nā ʻano mea kūkulu hale, me nā morta, plasters, grouts and tile adhesives. Hoʻohana ʻia ia i ka lāʻau lapaʻau, cosmetic a me ka hana meaʻai.
Pehea e hana ʻia ai ka HPMC viscosity haʻahaʻa?
Hana ʻia ka HPMC viscosity haʻahaʻa me ka hoʻohana ʻana i ke kaʻina hana like me ka HPMC kuʻuna. Hoʻololi ke kaʻina hana i ka cellulose maoli i ka methylcellulose, a laila hoʻohui i nā pūʻulu hydroxypropyl i ka methylcellulose e hana i ka HPMC. Hana ʻia ka HPMC viscosity haʻahaʻa ma o ka hoʻomalu ʻana i ke degere o ka hoʻololi ʻana (DS) a me ke kaumaha molekala o HPMC, ka hopena i kahi huahana viscosity haʻahaʻa.
He aha nā ʻano o ka HPMC viscosity haʻahaʻa ma laila?
Loaʻa ka HPMC viscosity haʻahaʻa ma nā ʻano papa like ʻole, kēlā me kēia me kona mau waiwai ponoʻī. Aia kekahi mau ʻano HPMC viscosity haʻahaʻa maʻamau:
- LV: haʻahaʻa viscosity papa me ka viscosity laula o 50 – 400 mPa.s. Hoʻohana maʻamau ʻia ʻo LV HPMC i nā plasters, morta a me nā mea hoʻopili tile.
- LVF: haʻahaʻa viscosity wikiwiki hoʻonohonoho papa me ka viscosity laula o 50 – 400 mPa.s. Hoʻohana mau ʻia ʻo LVF HPMC i ka hoʻonohonoho wikiwiki ʻana i nā tile adhesives a me nā grouts.
- LVT: Haʻahaʻa viscosity mānoanoa papa me ka viscosity laula o 400 – 2000 mPa.s. Hoʻohana pinepine ʻia ʻo LVT HPMC i nā hui hui, paʻi lole a me nā huahana mālama pilikino.
He aha nā mea hoʻohana o ka HPMC viscosity haʻahaʻa?
Hoʻohana nui ʻia ka HPMC haʻahaʻa haʻahaʻa i ka ʻoihana kūkulu ma ke ʻano he mānoanoa, adhesive a me ka mea mālama wai. ʻO kekahi mau noi maʻamau o ka HPMC viscosity haʻahaʻa i ke kūkulu ʻia ʻana:
- Nā Momo: Hoʻohana ʻia ka HPMC viscosity haʻahaʻa i nā morta e hoʻomaikaʻi ai i ka hana, adhesion a me ka paʻa ʻana o ka wai. Hoʻomānoanoa hoʻi ia i ka mortar, e maʻalahi ka hoʻopili ʻana a me ka hōʻemi ʻana i ka pilikia o ka pohā.
- Hoʻopalapala: Hoʻohana ʻia ka HPMC viscosity haʻahaʻa i ka plastering e hoʻomaikaʻi i ka hana a me ka paʻa ʻana o ka wai. Hoʻomaikaʻi pū ia i ke ʻano o kāu mau hoʻoheheʻe, e hoʻomaʻamaʻa i ko lākou mau ʻili.
- Hoʻopili Tile: Hoʻohana ʻia ka HPMC viscosity haʻahaʻa i nā mea hoʻopili tile e hoʻomaikaʻi i ka hana, adhesion a me ka paʻa ʻana o ka wai. Hoʻopaʻa ʻo ia i ka paʻa ʻana o ka tile adhesive ma hope o ke kau ʻana.
- Grouting: Hoʻohana ʻia ka HPMC viscosity haʻahaʻa i ka grouting e hoʻomaikaʻi i ka hana a me ka paʻa ʻana o ka wai. He kōkua nō hoʻi i ka pale ʻana i ka grout mai ka haki ʻana a me ka emi ʻana.
i ka hopena
ʻO ka HPMC haʻahaʻa haʻahaʻa he mea hoʻohui koʻikoʻi i ka ʻoihana kūkulu, hiki ke hoʻomaikaʻi i ka hana, adhesion a me ka paʻa ʻana o ka wai o nā mea hale. Ma ke ʻano he mea hana HPMC, ua kūpaʻa mākou i ka hana ʻana i nā huahana kiʻekiʻe e kūpono i nā pono o kā mākou mea kūʻai. E hoʻomau mākou i ka hana hou a me ka hoʻomaikaʻi ʻana i kā mākou huahana no ka hōʻoia ʻana e noho lākou ma ke poʻo o ka ʻoihana kūkulu.
