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 mole o ka cellulose ponoʻī. ʻO ia ʻano putty he ʻoluʻolu, he kiʻekiʻe ka hoʻoheheʻe wai, maʻalahi ka pulverize, ʻaʻohe ikaika, ʻaʻohe elasticity. Inā hoʻohana ʻia ka topcoat ma luna, ua maʻalahi ka haʻahaʻa 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 hoʻopili 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.
