Ka hopena o ka pauka latex redispersible i ka maikaʻi o ka pauda putty

E pili ana i ka pilikia he maʻalahi ka pauda putty i ka pauka, a ʻaʻole lawa ka ikaika.E like me kā mākou ʻike, pono e hoʻohui ʻia ka cellulose ether e hana i ka pauka putty, hoʻohana ʻia ka HPMC no ka putty pā, a ʻaʻole nui nā mea hoʻohana e hoʻohui i ka pauka latex redispersible.ʻAʻole nui ka poʻe e hoʻohui i ka pauka polymer i mea e mālama ai i nā kumukūʻai, akā ʻo ia hoʻi ke kī i ke kumu e maʻalahi ai ka putty maʻamau i ka pauka a pili i nā pilikia o ka huahana!

ʻO ka putty maʻamau (e like me 821 putty) i hana nui ʻia i ka pauka keʻokeʻo, kahi liʻiliʻi starch glue a me CMC (hydroxymethyl cellulose), a ua hana ʻia kekahi me ka methyl cellulose a me ka pauka Shuangfei.ʻAʻohe pili o kēia putty a ʻaʻole kū i ka wai.

Hiki i ka Cellulose ke komo i ka wai a pehu ma hope o ka hoʻoheheʻe ʻia ʻana i ka wai.Loaʻa i nā huahana mai nā mea hana like ʻole ka nui o ka lawe ʻana i ka wai.He kuleana ko Cellulose i ka mālama ʻana i ka wai ma ka putty.ʻO ka putty maloʻo wale nō ka ikaika no ka manawa pōkole, a e hoʻopau mālie ia i ka pauda ma hope o ka manawa lōʻihi.Pili loa kēia i ke ʻano molekala o cellulose ponoʻī.ʻO ia ʻano putty he ʻoluʻolu, he kiʻekiʻe ka hoʻoheheʻe wai, maʻalahi ka pulverize, ʻaʻohe ikaika, a ʻaʻohe elasticity.Inā hoʻohana ʻia ka topcoat ma luna, ua maʻalahi ka poha PVC haʻahaʻa a me ka huʻa;ʻO ka PVC kiʻekiʻe he maʻalahi ke emi a me ka haki;ma muli o ke kiʻekiʻe o ka wai, e hoʻopilikia ia i ka hoʻokumu ʻana o ke kiʻiʻoniʻoni a me ka hopena o ke kūkulu ʻana o ka topcoat.

Inā makemake ʻoe e hoʻomaikaʻi i nā pilikia ma luna o ka putty, hiki iā ʻoe ke hoʻoponopono i ke ʻano putty, hoʻohui i kahi pauka latex redispersible kūpono e hoʻomaikaʻi i ka ikaika hope o ka putty, a koho i ka hydroxypropyl methylcellulose HPMC kiʻekiʻe me ka maikaʻi ʻoiaʻiʻo.

I ke kaʻina hana o ka putty, inā ʻaʻole lawa ka nui o ka pauka latex redispersible i hoʻohui ʻia, a inā hoʻohana ʻia ka pauda latex haʻahaʻa no ka putty, he aha ka hopena i ka pauda putty?

ʻAʻole lawa ka nui o ka putty redispersible latex pauka, ʻo ka hōʻike pololei loa ʻo ia ka wehe ʻana o ka papa putty, pulverized ka ʻili, nui ka nui o ka pena i hoʻohana ʻia no ka topcoating, maikaʻi ʻole ka waiwai pae, ʻeleʻele ka ʻili ma hope o ka hoʻokumu ʻana o ke kiʻiʻoniʻoni, a he paʻakikī ke hana i kahi kiʻi pena paʻa.ʻO ia mau pā e maʻalahi i ka ʻili ʻana, blistering, peeling, a me ka haki ʻana o ke kiʻi pena.Inā koho ʻoe i ka pauda putty haʻahaʻa, ʻike maopopo ʻia nā kinoea ʻino e like me formaldehyde i hana ʻia ma ka paia e hōʻeha kino i nā poʻe ʻē aʻe.
