ʻO ka polyurea kahi polymer organik ʻo ia ka hopena o ka isocyanate me kahi amine i hoʻopau ʻia ka polyether resin, e hana ana i kahi mea like me ka plastic a i ʻole ka huila like me ka membrane seamless.
Pono ʻo Polyurea i ka hoʻomaʻamaʻa kūikawā a me nā mea hana no ka hoʻohana ʻana i ke kahua, inā i hoʻohana ʻia e like me ka hoʻopiha piha ʻana a i ʻole ka uhi ʻana i ke kahua.He papahana hoʻomau ʻo Shundi ohoʻomaʻamaʻa ʻaelikema kahi.Loaʻa nā applicators kūpono ma Kina.
E like me ke kānāwai maʻamau,ʻO ShundiHiki ke hoʻohana ʻia ka polyurea e loaʻa i kekahi mea i hiki ke hoʻokuʻu pololei ʻia i loko o nā ʻōnaehana hoʻomaʻemaʻe maʻamau.Hiki ke hoʻohana ʻia ma luna o nā ʻāpana ʻokoʻa, metala, lāʻau, fiberglass, ceramics surfaces.
Hoʻomaka ka Shundi polyureas e hoʻomohala i kā lākou mau waiwai kino i loko o nā minuke o ka noi.Hiki i ka polyurea ho'ōla ke pale i ka mahana mai -40 ℃ a 120 ℃, ʻOiai he kiʻekiʻe ke aniani o ka polyurea a me ka wela o nā mahana deflection, e ʻā ia ke ʻike ʻia i ka lapalapa pololei.E kinai ia iho ke hoopau ia ke ahi.Akā, loaʻa iā mākou ka polyurea pale ahi no nā koi kūikawā e like me nā alahele subway a me nā ala kaʻa.
He paʻakikī a palupalu paha ka polyurea ma muli o ke ʻano hoʻohālikelike a me ka hoʻohana ʻana.Loaʻa paha nā helu Durometer mai Shore A 30 (ʻoluʻolu loa) a hiki i Shore D 80 (paʻakikī loa).
ʻOiaʻiʻo, aia ʻelua mau ʻano ʻano o nā ʻōnaehana polyurea aliphatic i kēia manawa ma ka mākeke.ʻO kekahi ka ʻōnaehana maʻamau maʻamau i ke kaomi kiʻekiʻe / ka wela a ʻo kekahi ka mea i ʻike ʻia he ʻano ʻano ʻano "polyaspartic polyurea".He ʻokoʻa kēia ʻōnaehana polyaspartic i ka hoʻohana ʻana i kahi mea resin ester-based a ʻoi aku ka lōʻihi o ke ola o ka ipuhao.Hiki ke hoʻohana lima ʻia me ka hoʻohana ʻana i nā wili;nā pulupulu;rake a i ʻole nā mea ea ʻole.ʻO nā ʻōnaehana aspartic ʻaʻole ia ka uhi kūkulu kiʻekiʻe maʻamau o nā ʻōnaehana polyurea "wela wela".Pono e hana ʻia nā ʻōnaehana polyurea ʻala maʻamau ma o ke kaomi kiʻekiʻe, nā ʻāpana ʻāpana i hoʻomehana ʻia a hoʻoheheʻe ʻia ma ke ʻano impingement spray-gun.He ʻoiaʻiʻo nō hoʻi kēia no ka mana aliphatic o kēia ʻano ʻōnaehana, ʻo ka ʻokoʻa mua ka paʻa kala o nā ʻōnaehana aliphatic.
Loaʻa i kēlā me kēia huahana ma kā mākou pūnaewele nā palapala kiʻi Resistance Chemical ma lalo o ka pā palapala.
ʻO SWD959 kekahi o kā mākou mea hana i ka wā e pili ana i ka hoʻolaha kemika ʻoi loaEia kekahi, inā loaʻa iā ʻoe kahi kemika kikoʻī āu e hana nei (a i ʻole kahi noi kikoʻī), e ʻoluʻolu ekāhea iā mā˚ouno laila hiki iā mākou ke kōkua iā ʻoe e hoʻoholo i ka ʻōnaehana maikaʻi loa no kāu mau pono.
Loaʻa iā mākou ka uhi ʻana o ka urethane maʻemaʻe a me ka uhi polyaspartic paʻa i loaʻa ka hana kiʻekiʻe o ke kūʻē kemika i nā solvents, acids a i ʻole nā mea ʻē aʻe.Hiki iā ia ke pale i ka 50% H2SO4a me 15% HCL.
Ma muli o ka hoʻokumu ʻana, ʻoiai ma nā ʻano hana kūikawā a Shundi, ʻaʻole e emi ka polyurea ma hope o ka hoʻōla ʻana.
Eia naʻe, he nīnau maikaʻi kēia e nīnau aku ai i kekahi āu e koho ai e kūʻai i mea mai - e emi ana kāu mea a ʻaʻole paha?
Loaʻa iā mākou ka huahana kūpono no kēia ʻano noi, SWD9005, Ua hoʻāʻo nui ʻia kēia huahana i ka ʻoihana mining, a ua hana mau ma luna o nā manaʻo.
No nā noi hoʻolulu / kila, e hoʻomanaʻo ʻaʻole like ka PUA (polyureas) a me ka epoxy.ʻO lāua nā wehewehe ʻelua o nā ʻenehana / ʻano huahana.Hana maikaʻi nā ʻōnaehana PUA no ka hoʻomaʻamaʻa ʻana, akā pono lākou e hoʻonohonoho pono ʻia no kēlā noi.
ʻOiai ʻoi aku ka paʻakikī o nā ʻōnaehana epoxy, ʻoi aku ka maʻalahi o nā ʻōnaehana PUA a me nā helu permeation haʻahaʻa no nā ʻōnaehana i kūkulu pono ʻia.ʻOi aku ka wikiwiki o ka PUA i ka hoʻihoʻi ʻana i ka lawelawe ma ke ʻano holoʻokoʻa - hoʻōla ka polyurea i loko o nā hola i hoʻohālikelike ʻia me nā lā (a i kekahi manawa he pule) no nā epoxies.Eia naʻe, ʻo ka pilikia nui me kēia ʻano hana a me nā substrate kila, ʻo ia ka hoʻomākaukau ʻana i ka ʻili he mea koʻikoʻi.Pono e hana pono ʻia kēia.ʻO kēia kahi i loaʻa ai nā pilikia i ka wā e hoʻāʻo ai i kēia mau ʻano papahana.
E nānā i kā mākouPalapala noiʻaoʻao hihiano nā profiles ma kēia a me nā ʻano noi ʻē aʻe he nui.
ʻO ka maʻamau, ʻoi aku ka maikaʻi o ka pena hale 100% acrylic latex maikaʻi ma luna o ka polyurea sprayed.ʻOi aku ka maikaʻi o ka uhi ʻana i ka polyurea (ma mua o ka wā ma hope) i loko o 24 mau hola o ka noi.Hoʻoikaika kēia i ka adhesion maikaʻi loa.Paipai ʻia ka polyaspartic uv resistance topcoat e hoʻohana ma luna o ka polyurea no ka ʻoi aku ka maikaʻi o ka ʻelemakule a me ke kū ʻana i ka wā.
