I ka wā wili, wili a me ka hana ʻana o ka aila a me ke kinoea maoli, hiki i ka pā pūnāwai ke lilo i ka wai, e hoʻololi ai i ke anawaena o ka pūnāwai a hāʻule, no laila ʻaʻole hiki ke hoʻokō maʻamau ka papahana, a haʻalele paha i ka hapalua. No laila, pono e hoʻoponopono i nā ʻāpana kino o ka lepo wili e like me nā loli i nā kūlana geological o kēlā me kēia māhele, e like me ka hohonu hohonu, ka mahana, a me ka mānoanoa. ʻO CMC ka huahana maikaʻi loa e hiki ke hoʻoponopono i kēia mau ʻāpana kino. ʻO kāna mau hana nui:
Hiki i ka lepo i loko o ka CMC ke ho'olilo i ka pā punawai i keke kānana lahilahi, pa'a a ha'aha'a, hiki ke pale i ka wai o ka shale, pale i ka ho'ohehe'e 'ana i nā 'oki'oki, a ho'emi i ka hiolo 'ana o ka pā.
ʻO ka lepo i loaʻa i ka CMC kahi ʻano mea hoʻokele wai hoʻoheheʻe kiʻekiʻe, hiki iā ia ke hoʻomalu i ka nalowale o ka wai ma kahi pae ʻoi aku ka maikaʻi ma kahi haʻahaʻa haʻahaʻa (0.3-0.5%), a ʻaʻole ia e hoʻopilikia i nā waiwai ʻē aʻe o ka lepo. , e like me ka viscosity kiʻekiʻe loa a i ʻole ka ikaika ʻoki.
Hiki i ka lepo CMC ke kū'ē i ka wela kiʻekiʻe, a hiki ke hoʻohana ʻia i loko o kahi kaiapuni kiʻekiʻe ma kahi o 140 ° C, e like me nā huahana kiʻekiʻe-substitution a me nā huahana kiʻekiʻe-viscosity, hiki ke hoʻohana ʻia i kahi kūlana wela kiʻekiʻe o 150-170 °C.
ʻAʻole kū i ka paʻakai ka lepo i loaʻa iā CMC. ʻO nā hiʻohiʻona o ka CMC ma ke ʻano o ka paʻakai paʻakai: ʻaʻole hiki iā ia ke mālama i ka hiki ke hōʻemi i ka nalowale o ka wai ma lalo o kahi paʻakai paʻakai, akā hiki iā ia ke mālama i kekahi waiwai rheological, he liʻiliʻi liʻiliʻi i hoʻohālikelike ʻia me ka wai maʻemaʻe. ; ʻO ia nā mea ʻelua Hiki ke hoʻohana ʻia i loko o ka wai wili pālolo ʻole a me ka lepo i loko o ka wai paʻakai. Hiki i kekahi mau wai wili ke kū i ka paʻakai, a ʻaʻole loli nui nā waiwai rheological. Ma lalo o 4% ka paʻakai paʻakai a me ka wai hou, ua hoʻonui ʻia ka lakio hoʻololi viscosity o CMC paʻakai paʻakai i ʻoi aku ma mua o 1, ʻo ia hoʻi, hiki ʻole ke hoʻololi ʻia ka viscosity i kahi paʻakai kiʻekiʻe.
Hiki i ka lepo CMC ke hoʻomalu i ka rheology o ka lepo.CMCʻAʻole hiki ke hōʻemi wale i ka nalowale o ka wai, akā hoʻonui i ka viscosity.
1. CMC-i loko o ka lepo hiki ke hana i ka pā punawai i mea lahilahi, paakiki a haʻahaʻa-permeability kānana keke, e hoemi ana i ka wai. Ma hope o ka hoʻohui ʻana i ka CMC i ka ʻōpala, hiki i ka rig wili ke loaʻa i ka ikaika ʻoki mua haʻahaʻa, i hiki i ka ʻōpala ke hoʻokuʻu maʻalahi i ke kinoea i hoʻopili ʻia i loko, a i ka manawa like, hiki ke hoʻolei koke ʻia ka ʻōpala i loko o ka lua lepo.
2. E like me nā ho'opuehu ho'oku'u 'ia, loa'a ke ola o ka wili lepo. Hiki i ka hoʻohui ʻana i ka CMC ke paʻa a hoʻolōʻihi i ke ola o ka papa.
3. ʻAʻole hiki ke hoʻopili ʻia ka lepo i loaʻa i ka CMC e ka pala, a ʻaʻohe pono e mālama i kahi waiwai pH kiʻekiʻe a hoʻohana i nā preservatives.
4. He kūpaʻa maikaʻi ka lepo me ka CMC a hiki ke hōʻemi i ka nalowale o ka wai inā ʻoi aku ka mahana ma luna o 150 degere.
