He aha ka hana nui o ka hoʻohana ʻana o HPMC i ka pauka putty

I loko o ka pauka putty, hoʻokani ʻo ia i ʻekolu hana o ka mānoanoa, paʻa wai a me ke kūkulu ʻana.

Mānoanoa: Hiki ke mānoanoa ka cellulose e hoʻopaneʻe a mālama i ka hoʻonā ʻaʻahu i luna a i lalo, a pale aku i ka haʻalulu.

Hoʻopaʻa wai: E hoʻomaloʻo mālie i ka pauka putty e kōkua i ka hana ʻana o ka calcium lehu ma lalo o ka wai.

Hana: He hopena lubricating ka Cellulose, hiki ke hana i ka pauka putty i ke kūkulu maikaʻi.

ʻOi aku ka nui o ka hana palekana ma mua o Mount Tai

ʻAʻole komo ʻo HPMC i nā hopena kemika, akā he hana kōkua wale nō. ʻO ka hoʻohui ʻana i ka wai i ka pauka putty a kau ʻia ma ka paia he hopena kemika, no ka mea, ua hana ʻia nā mea hou. E kiʻi i ka pauda putty ma ka paia mai ka paia, e wili a lilo i pauda, ​​a hoʻohana hou. ʻAʻole ia e hana no ka mea ua hoʻokumu ʻia nā mea hou (calcium carbonate). ʻAe. ʻO nā mea nui o ka pauka calcium lehu: he hui ʻana o Ca(OH2, CaO a me kahi mea liʻiliʻi o CaCO3, CaO+H2O=Ca(OH2-Ca(OH2+CO2==CaCO3↓+H2O) ʻO ka hopena o ka calcium lehu ma CO2 i ka wai a me ka ea Ma lalo o kēia ʻano, hoʻokumu ʻia ka calcium carbonate, ʻoiai ʻo HPMC wale nō ka mālama ʻana i ka wai a ʻaʻole kōkua i ka ʻoi aku ka maikaʻi o ka calcium.

ʻO ka lilo o ka pauka o ka pauka putty e pili nui i ka maikaʻi o ka calcium lehu, a ʻaʻohe mea liʻiliʻi me HPMC. ʻO ka haʻahaʻa o ka calcium haʻahaʻa o ka calcium hina a me ka ratio kūpono ʻole o CaO a me Ca(OH2 i ka calcium hina e lilo ai ka pauda.
