Hoʻohana nui ʻia nā cellulose ethers i ka ʻoihana kūkulu hale ma muli o ko lākou paʻa wai maikaʻi loa, nā waiwai mānoanoa a me nā waiwai hoʻopili. Hoʻomaikaʻi lākou i ke kahe a me ka hiki ke hana ʻia o nā mea sima a hoʻomaikaʻi i nā waiwai mechanical o ka huahana hope loa. Hoʻohana pinepine ʻia nā Putties i ka ʻoihana kūkulu hale e hoʻopiha i nā māwae, nā lua a me nā hemahema ʻē aʻe i nā paia a me nā kaupaku. ʻO ka hoʻohana ʻana i nā cellulose ethers i loko o nā pauka putty hiki ke hoʻomaikaʻi i ka hana, ka manawa hoʻonohonoho a me ka maikaʻi holoʻokoʻa o ka huahana. E kūkākūkā kēia ʻatikala i ka hopena o nā viscosities like ʻole o nā cellulose ethers i ka pauka putty.
Nā ʻano o nā ethers cellulose:
Aia nā ʻano like ʻole o nā cellulose ethers e komo pū ana me ka methylcellulose (MC), hydroxypropylmethylcellulose (HPMC), ethylcellulose (EC) a me ka carboxymethylcellulose (CMC). He cellulose ether kaulana ʻo HPMC i ka ʻoihana kūkulu hale ma muli o kona paʻa wai maikaʻi loa, ka mānoanoa a me nā waiwai hoʻopili. Loaʻa nā HPMC i nā viscosities like ʻole, mai ka haʻahaʻa a i ke kiʻekiʻe.
Ka hopena o ka cellulose ether ma ka pauka putty:
Hoʻohana ʻia ka pauka Putty e hoʻopiha i nā māwae, nā lua a me nā hemahema ʻē aʻe i nā paia a me nā kaupaku. ʻO ka hoʻohana ʻana i nā cellulose ethers i loko o nā pauka putty hiki ke hoʻomaikaʻi i ka hana a me ka manawa hoʻonohonoho o ka huahana. Hiki i ka Cellulose ether ke hoʻomaikaʻi i ka hana a me ka hoʻopili ʻana o ka pauka putty. Eia ka hopena o nā viscosities like ʻole o nā cellulose ethers ma ka pauka putty:
1. HPMC mānoanoa haʻahaʻa:
Hiki i ka HPMC mānoanoa haʻahaʻa ke hoʻomaikaʻi i ka wai a me ka hana o ka pauka putty. Hoʻomaikaʻi pū ia i ka manawa hoʻonohonoho o ka huahana. ʻOi aku ka haʻahaʻa o ka mahana gelation o ka HPMC mānoanoa haʻahaʻa, hiki ke pale i ka pauka putty mai ka paʻakikī wikiwiki. Hiki iā ia ke hoʻomaikaʻi i ka hoʻopili ʻana a me ke kuʻikahi o ka huahana. He kūpono ka HPMC mānoanoa haʻahaʻa no ka pauka putty e pono ai ka hana maikaʻi a me ka laumania.
2. HPMC mānoanoa waena:
Hiki i ka HPMC mānoanoa waena ke hoʻomaikaʻi i nā waiwai thixotropic o ka pauka putty. Hiki iā ia ke hoʻomaikaʻi i ka paʻa ʻana o ka wai a me ka hana hoʻopili o ka huahana. Hiki i ka HPMC mānoanoa waena ke hoʻomaikaʻi i nā waiwai mechanical o ka huahana, e like me ka ikaika a me ke kūpaʻa. He kūpono ia no ka pauka putty e pono ai ka paʻa ʻana o ka wai maikaʻi a me ke kūpaʻa.
3. HPMC mānoanoa kiʻekiʻe:
Hiki i ka HPMC mānoanoa kiʻekiʻe ke hoʻomaikaʻi i ka hana mānoanoa a me ka hana anti-sag o ka pauka putty. Hiki iā ia ke hoʻomaikaʻi i ka paʻa ʻana o ka wai a me ka hana hoʻopaʻa ʻana o ka huahana. Hiki i ka HPMC mānoanoa kiʻekiʻe ke hoʻomaikaʻi i nā waiwai mechanical o ka huahana, e like me ka ikaika a me ke kūpaʻa. He kūpono ia no ka pauka putty e koi ana i ka hana mānoanoa kiʻekiʻe a me ka hana anti-sag.
i ka hopena:
Hoʻohana nui ʻia nā ethers cellulose i ka ʻoihana kūkulu hale ma muli o ko lākou paʻa wai maikaʻi loa, nā waiwai mānoanoa a me nā waiwai hoʻopaʻa. Ua lilo ʻo HPMC i cellulose ether kaulana i ka ʻoihana kūkulu hale ma muli o kona mau waiwai maikaʻi loa. Loaʻa nā viscosities like ʻole o HPMC, mai ka haʻahaʻa a i ke kiʻekiʻe. Hiki i ka hoʻohana ʻana i nā ethers cellulose me nā viscosities like ʻole ke hoʻomaikaʻi i ka hana, ka manawa hoʻonohonoho, ka hana thixotropic, ka paʻa wai, ka hana hoʻopaʻa a me nā waiwai mechanical o ka pauka putty. Hiki i ka hoʻohana ʻana i nā ethers cellulose ke hoʻomaikaʻi i ka maikaʻi a me ka hana o nā pauka putty, e kūpono ai lākou no nā noi like ʻole i ka ʻoihana kūkulu hale.
