ʻO nā pauka polymer redispersible (RDP) he mau huila paʻakikī o nā polymers a me nā mea hoʻohui i hoʻohana nui ʻia i nā mea hana, ʻoi aku hoʻi i ka hana ʻana i nā morta maloʻo.He kuleana koʻikoʻi kēia mau pauka i ka hoʻomaikaʻi ʻana i ka hana a me nā hiʻohiʻona o nā mea hana like ʻole e like me nā tile adhesives, grouts, self-leveling compounds a me nā plasters cementitious.
ʻO nā mea nui:
Kumu polimer:
Ethylene vinyl acetate (EVA): Hoʻohana maʻamau ʻia ka EVA copolymer ma RDP ma muli o kāna mau waiwai hana kiʻiʻoniʻoni maikaʻi loa, adhesion, a me ka maʻalahi.Hiki ke hoʻololi i ka mea vinyl acetate i loko o ka copolymer e hoʻololi i nā waiwai o ka polymer.
Vinyl Acetate vs. Ethylene Carbonate: Ma muli o nā koi kūikawā o ka noi, hiki i nā mea hana ke hoʻohana i ka ethylene carbonate ma kahi o ka vinyl acetate.Ua hoʻomaikaʻi ʻo Ethylene carbonate i ka pale ʻana i ka wai a me ka hoʻopili ʻana i nā kūlana haʻahaʻa.
Acrylics: Hoʻohana ʻia nā polymers Acrylic, me nā acrylic maʻemaʻe a i ʻole copolymers, no ko lākou kūʻokoʻa kūʻokoʻa i ka wā, lōʻihi, a me ka versatility.Ua ʻike ʻia lākou no ka hāʻawi ʻana i ka adhesion maikaʻi loa i nā ʻano substrates.
Colloid pale:
Hydroxypropyl methylcellulose (HPMC): ʻO HPMC kahi colloid pale i hoʻohana mau ʻia ma RDP.Hoʻonui ia i ka redispersibility o nā ʻāpana polymer a hoʻonui i nā waiwai holoʻokoʻa o ka pauka.
ʻO ka waiʻona polyvinyl (PVA): ʻO PVA kekahi colloid pale e kōkua i ka paʻa a me ka hoʻopuehu ʻana o nā ʻāpana polymer.He kuleana nō hoʻi ia i ka mālama ʻana i ka viscosity o ka pauka.
Mea hoʻopalapala:
ʻO Dibutyl Phthalate (DBP): ʻO DBP kahi laʻana o ka plasticizer i hoʻohui pinepine ʻia i RDP e hoʻomaikaʻi i ka maʻalahi a me ka hana.Kōkua ia i ka hoʻohaʻahaʻa i ka mahana hoʻololi aniani o ka polymer, e ʻoi aku ka elastic.
mea hoʻopiha:
Calcium Carbonate: Hiki ke hoʻohui ʻia nā mea hoʻopihapiha e like me ka calcium carbonate e hoʻonui i ka nui o nā pauka a hāʻawi i kahi ala kūpono e hoʻoponopono ai i nā waiwai e like me ke ʻano, porosity a me ka opacity.
Stabilizers a me nā antioxidants:
Stabilizers: Hoʻohana ʻia kēia e pale i ka hōʻino ʻana o ka polymer i ka wā mālama a me ka hana ʻana.
Nā Antioxidants: Mālama nā Antioxidants i ka polymer mai ka hoʻohaʻahaʻa oxidative, e hōʻoia ana i ka lōʻihi o ka RDP.
Nā hana o kēlā me kēia ʻāpana:
Polymer base: Hāʻawi i nā waiwai hana kiʻiʻoniʻoni, adhesion, maʻalahi a me ka ikaika mechanical i ka huahana hope.
Colloid pale: Hoʻonui i ka redispersibility, kūpaʻa a me ka hoʻopuehu ʻana o nā ʻāpana polymer.
Plasticizer: Hoʻomaikaʻi i ka maʻalahi a me ke kaʻina hana.
Nā mea hoʻopiha: Hoʻoponopono i nā waiwai e like me ke ʻano, porosity, a me ka opacity.
Stabilizers a me nā antioxidants: Kāohi i ka polymer degradation i ka wā mālama a me ka hana ʻana.
i ka hopena:
ʻO ka pauka polymer redispersible (RDP) he mea maʻalahi a koʻikoʻi i nā mea kūkulu hale hou.ʻO kāna hana kemika, me nā polymers e like me ka EVA a i ʻole nā resins acrylic, nā colloids pale, plasticizers, fillers, stabilizers a me antioxidants, ua hoʻonohonoho pono ʻia e hoʻokō i nā koi kikoʻī o kēlā me kēia noi.ʻO ka hui pū ʻana o kēia mau ʻāpana e kōkua i ka hoʻomaikaʻi ʻana i ka pauka redispersibility, ka ikaika paʻa, ka maʻalahi a me ka hana holoʻokoʻa i loko o nā formulations mortar mix maloʻo.
