I kēia mau lā iho nei, ua nui nā nīnau mai nā mea kūʻai aku e pili ana i ka pauka putty, e like me kona ʻano e pulverize a i ʻole kona hiki ʻole ke hoʻoikaika. Ua ʻike ʻia ʻo ka hoʻohui ʻanaʻEtera cellulosehe mea pono ia e hana i ka pauka putty, a ʻaʻole hoʻohui ka nui o nā mea hoʻohana i ka pauka latex dispersible. ʻAʻole hoʻohui ka nui o ka poʻe i ka pauka pipili e mālama i nā kumukūʻai, akā ʻo ia hoʻi ke kī i ke kumu e maʻalahi ai ka putty maʻamau i ka pulverization a me nā pilikia maikaʻi o ka huahana!
Pauka latex hiki ke hoʻoheheʻe hou ʻia
ʻO ka putty maʻamau (e like me ka putty 821) ua hana nui ʻia me ka pauka keʻokeʻo, kahi liʻiliʻi o ka pipili starch, a me CMC (hydroxymethyl cellulose), a aia kekahi mau mea i hana ʻia me ka methyl cellulose a me ka pauka lele pālua. ʻAʻohe pipili o kēia ʻano putty a ʻaʻole ia e pale i ka wai.
Ma hope o ka hoʻoheheʻe ʻana o ka cellulose a me ka wai, hiki iā ia ke omo i ka wai a hoʻonui. He ʻokoʻa ka nui o ka omo ʻana o ka wai o nā huahana mai nā mea hana like ʻole, a he kuleana paʻa wai ko ka cellulose i loko o ka putty. Ma hope o ka maloʻo ʻana, loaʻa i ka putty kahi ikaika no kekahi manawa, akā i ka hala ʻana o ka manawa, e nalowale mālie ka pauka, kahi e pili pono ana i ke ʻano molekala o ka cellulose ponoʻī. He palupalu kēia ʻano putty, he nui ka omo ʻana o ka wai, he maʻalahi i ka pauka ʻana, nele i ka ikaika, a me ka elasticity. Inā hoʻopili ʻia ka topcoat ma luna, he maʻalahi ka PVC haʻahaʻa i ka blistering; ʻO ka PVC kiʻekiʻe he maʻalahi i ka dehydration, shrinkage, a me ka haki; Ma muli o kona nui o ka omo wai, hoʻopilikia ia i ka hoʻokumu ʻana o ka kiʻiʻoniʻoni a me ka hopena kūkulu o ka topcoat.
No ka hoʻomaikaʻi ʻana i nā pilikia i luna me ka putty, hiki iā ʻoe ke hoʻoponopono i ke ʻano putty a hoʻohui i kahi pauka latex redispersible e hoʻomaikaʻi i ka ikaika hope o ka putty. E koho i kahi hydroxypropyl methyl cellulose kiʻekiʻeHPMCme ka hōʻoiaʻiʻo maikaʻi.ʻO ka hydroxypropyl methyl celluloseLoaʻa iā ia ka nui o ka paʻa ʻana o ka wai o ka cellulose kiʻekiʻe, hiki ke hoʻomaʻū piha i ka mea maka o ka putty a hoʻomaikaʻi i ka maikaʻi o ka putty.
He aha ka hopena ma ka pauka putty inā ʻaʻole lawa ka nui o ka pauka latex redispersible i hoʻohui ʻia i ka wā o ke kaʻina hana putty, a inā hoʻohana ʻia ka pauka latex kikoʻī haʻahaʻa haʻahaʻa?
ʻO ka nui lawa ʻole opauka latex hiki ke hoʻoheheʻe hou ʻiaʻO ka mea i hoʻohui ʻia i ka putty ka hōʻike pololei loa o ka papa putty wehe, ka pauka ʻili, ka hoʻohana nui ʻana i ka pena i ka wā e hoʻopili ai i ka topcoat, ka pae maikaʻi ʻole, ka ʻili ʻino ma hope o ka hoʻokumu ʻana o ka ʻili, a me ka paʻakikī i ke kūkulu ʻana i kahi ʻili pena mānoanoa. He maʻalahi kēlā mau paia i ka ʻili ʻana, ka pehu ʻana, ka ʻili ʻana, a me ka nahā ʻana o ka ʻili pena. Inā koho ʻia ka pauka putty haʻahaʻa, ʻike maopopo ʻia ke kiʻekiʻe o ka pōʻino i ke kino o ke kanaka i hoʻokumu ʻia e nā kinoea ʻino e like me ka formaldehyde i hana ʻia ma ka paia.
No ka hoʻololi ʻana i ke kūlana o kēia manawa, pono e wehe i nā putty maikaʻi ʻole me ka waiho ʻole ʻana i kekahi koena, a laila kūʻai i ka putty kūpono a me ka pena latex! I mea e pale aku ai i nā pohō pono ʻole, pono e hoʻāʻo nā mea kūʻai aku e koho i nā huahana mai nā lama nui me ka hōʻoia maikaʻi no ka maʻalahi o ke koho ʻana i ka putty.
He loea ʻo longou Company i ka hana ʻana a me ke kūʻai aku ʻana i nā olonā lāʻau, starch ether, hydroxypropyl methyl cellulose, redispersible latex powder
