Nā mea hana HPMC-ka hopena o nā viscosities like ʻole o ka cellulose ethers ma ka pauka putty

hoʻolauna:

Hoʻohana nui ʻia nā cellulose ethers i ka ʻoihana kūkulu ma muli o kā lākou paʻa wai maikaʻi, mānoanoa a me nā waiwai paʻa. Hoʻonui lākou i ka kahe a me ka hana o nā mea i hoʻokumu ʻia i ka sima a hoʻomaikaʻi i nā ʻano mechanical o ka huahana hope. Hoʻohana pinepine ʻia nā putties i ka ʻoihana hana e hoʻopiha i nā māwae, nā lua a me nā hemahema ʻē aʻe i nā paia a me nā kaupaku. Hiki i ka hoʻohana ʻana i nā cellulose ethers i nā pauka putty ke hoʻomaikaʻi i ka hana, hoʻonohonoho manawa a me ka maikaʻi o ka huahana. E kūkākūkā kēia ʻatikala i ka hopena o nā viscosities like ʻole o ka cellulose ethers ma ka pauka putty.

Nā ʻano o ka cellulose ethers:

Aia nā ʻano like ʻole o ka cellulose ethers me ka methylcellulose (MC), hydroxypropylmethylcellulose (HPMC), ethylcellulose (EC) a me ka carboxymethylcellulose (CMC). He cellulose ether kaulana ʻo HPMC i ka ʻoihana kūkulu ma muli o kona paʻa wai maikaʻi, mānoanoa a me nā waiwai pili. Hiki mai ka HPMC ma nā ʻano viscosities like ʻole, mai ka haʻahaʻa a hiki 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 ma nā paia a me nā kaupaku. ʻO ka hoʻohana ʻana i nā cellulose ethers i nā pauka putty hiki ke hoʻomaikaʻi i ka hana a me ka hoʻonohonoho manawa 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 ka cellulose ethers ma ka pauka putty:

1. HPMC haʻahaʻa viscosity:

Hiki i ka HPMC viscosity haʻahaʻa ke hoʻomaikaʻi i ka wai a me ka hana o ka pauka putty. Hoʻonui ia i ka manawa hoʻonohonoho o ka huahana. Loaʻa i ka HPMC haʻahaʻa haʻahaʻa haʻahaʻa ka wela gelation, hiki ke pale i ka pauka putty mai ka paʻakikī loa. Hiki iā ia ke hoʻomaikaʻi i ka adhesion a me ka hui ʻana o ka huahana. He kūpono ka HPMC viscosity haʻahaʻa no ka pauka putty e koi ana i ka hana maikaʻi a me ka maʻalahi.

2. HPMC viscosity waena:

Hiki i ka HPMC viscosity liʻiliʻi 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 paʻa ʻana o ka huahana. Hiki i ka HPMC medium-viscosity ke hoʻomaikaʻi i nā waiwai mechanical o ka huahana, e like me ka ikaika a me ka lōʻihi. He kūpono ia no ka pauka putty e koi ana i ka hoʻopaʻa wai maikaʻi a me ka cohesiveness.

3. HPMC kiʻekiʻe viscosity:

Hiki i ka HPMC viscosity kiʻekiʻe ke hoʻomaikaʻi i ka 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 paʻa ʻana o ka huahana. Hiki i ka HPMC viscosity kiʻekiʻe ke hoʻomaikaʻi i nā waiwai mechanical o ka huahana, e like me ka ikaika a me ka lōʻihi. He kūpono ia no ka pauka putty e koi ana i ka mānoanoa kiʻekiʻe a me ka hana anti-sag.

i ka hopena:

Hoʻohana nui ʻia nā cellulose ethers i ka ʻoihana kūkulu ma muli o kā lākou paʻa wai maikaʻi, mānoanoa a me nā waiwai paʻa. Ua lilo ʻo HPMC i mea kaulana cellulose ether i ka ʻoihana kūkulu ma muli o kāna mau waiwai maikaʻi loa. Hiki mai ka HPMC ma nā ʻano viscosities like ʻole, mai ka haʻahaʻa a hiki i ke kiʻekiʻe. Hiki i ka hoʻohana ʻana i nā cellulose ethers me nā viscosities like ʻole ke hoʻomaikaʻi i ka hana, hoʻonohonoho manawa, hana thixotropic, paʻa wai, hana hoʻopaʻa a me nā waiwai mechanical o ka pauka putty. Hiki i ka hoʻohana ʻana i nā cellulose ethers ke hoʻomaikaʻi i ka maikaʻi a me ka hana ʻana o nā pauka putty, e kūpono ana iā lākou no nā noi like ʻole i ka ʻoihana kūkulu.
