He aha ka Wall putty?

ʻO Wall putty kahi ʻano mea i hoʻohana ʻia e hoʻomaʻemaʻe i ka ʻili o nā paia ma ka hoʻopiha ʻana i nā āpau a me ka hoʻohaʻahaʻa ʻana.ʻO ia ka pauka sima i hui pū ʻia me ka wai e hana i kahi ʻano paʻa like e hiki ke hoʻopili ʻia i nā paia.ʻO kekahi o nā mea nui o ka putty pā he cellulose ether.

ʻO ka cellulose ether kahi polymer hiki ke hoʻoheheʻe ʻia i ka wai i loaʻa mai ka cellulose maoli.Hana ʻia ia ma ke kemika hoʻololi ʻana i ka cellulose, kahi polymer kūlohelohe i loaʻa i loko o nā paia o nā mea kanu.Hoʻohana nui ʻia ka cellulose ether i ka ʻoihana kūkulu e like me ka mānoanoa, stabilizer, binder, a me ka mea mālama wai.Hoʻohana ʻia ia i ka hana ʻana i nā huahana mea kūʻai aku, e like me ka meaʻai, nā mea hoʻonaninani, a me nā lāʻau lapaʻau.

I ka hihia o ka putty pā, hana ʻo cellulose ether ma ke ʻano he mānoanoa a me ka mea hoʻopaʻa.Ke hoʻohui ʻia ka cellulose ether i ka hui ʻana o ka putty pā, hoʻomaikaʻi ʻo ia i kāna hana ma ka hāʻawi ʻana i kahi ʻano maʻalahi.He mea maʻalahi kēia i ka hoʻopili ʻana i ka putty i nā paia a hōʻoia i ka pili pono ʻana i ka ʻili.Kōkua pū ka cellulose ether i ka pale ʻana i ka emi ʻana a me ka haki ʻana o ka putty pā ma hope o ka maloʻo ʻana.

ʻO kekahi hana koʻikoʻi o ka cellulose ether i ka putty pā ʻo ia ka hiki ke mālama i ka wai.Pono e ho'oma'ema'e ka pā putty no kekahi manawa ma hope o ka ho'ohana 'ana i mea e malo'o pono ai a ho'opa'a pa'a me ka ili o ka paia.Kōkua ka cellulose ether i ka hoʻopaʻa ʻana i ka wai i loko o ka hui putty, kahi e hoʻolohi ai i ke kaʻina hoʻomaloʻo a hōʻoia i ka hoʻonohonoho pono ʻana o ka putty.

Hoʻopili nui ʻia ka maikaʻi a me ka hana o ka putty pā e ke ʻano a me ka nui o ka cellulose ether i hoʻohana ʻia.Aia nā ʻano like ʻole o ka cellulose ether i loaʻa i ka mākeke, e like me hydroxyethyl cellulose (HEC), methyl cellulose (MC), a me carboxymethyl cellulose (CMC).Loaʻa i kēlā me kēia ʻano nā ʻano a me nā ʻano like ʻole, a ʻo ke koho ʻana i ke ʻano kūpono a me ka nui he mea koʻikoʻi ia i ka hoʻoholo ʻana i ka maikaʻi o ka putty pā.

I ka hōʻuluʻulu ʻana, he hana koʻikoʻi ka cellulose ether i ka hana ʻana i ka putty pā.Hāʻawi ia i nā waiwai mānoanoa, hoʻopaʻa ʻana, a me ka wai paʻa i ka hui putty, e hōʻoiaʻiʻo ana i kāna hana, pale i ka shrinkage a me ka ʻoki ʻana, a hōʻoia i ka maloʻo pono ʻana a me ka hoʻopaʻa ʻana i ka ʻili o ka pā.ʻO ke koho ʻana i ke ʻano kūpono a me ka nui o ka cellulose ether he mea nui ia i ka hana ʻana i ka putty pā kiʻekiʻe kiʻekiʻe e kū ana i nā kūlana i makemake ʻia o ka ʻoihana kūkulu.
