E hoʻolauna e pili ana i ka cellulose ethers

01. Ka noi nui o cellulose ether HPMC?

Hoʻohana nui ʻia ka HPMC i ka mīkini hana, ka pena wai, ka resin synthetic, ka seramika, ka lāʻau lapaʻau, ka meaʻai, ka lole, nā mea hoʻonaninani, ka paka, a me nā ʻoihana ʻē aʻe. Hoʻokaʻawale ʻia i ka papa hana, ka papa meaʻai, ka lāʻau lapaʻau, ka papa hana PVC a me ka papa kemika i kēlā me kēia lā.

02. He aha nā ʻano o ka cellulose?

ʻO nā celluloses maʻamau he MC, HPMC, MHEC, CMC, HEC, EC
I waena o lākou, hoʻohana nui ʻia ʻo HEC a me CMC i nā uhi wai.
Hiki ke hoʻohana ʻia ʻo CMC i nā ceramics, nā aila, nā meaʻai a me nā māla ʻē aʻe
Hoʻohana nui ʻia ʻo EC i ka lāʻau lapaʻau, ka paʻi kālā uila a me nā māla ʻē aʻe
Hoʻokaʻawale ʻia ʻo HPMC i nā kikoʻī like ʻole no ka mortar, lāʻau lapaʻau, meaʻai, ʻoihana PVC, nā huahana kemika i kēlā me kēia lā a me nā ʻoihana ʻē aʻe.

03. He aha ka ʻokoʻa ma waena o HPMC a me MHEC i ka noi?

ʻO nā waiwai o nā ʻano cellulose ʻelua, ʻoi aku ka maikaʻi, akā ʻoi aku ka maikaʻi o ke kūpaʻa kiʻekiʻe o ka MHEC, ʻoi aku ka maikaʻi i ke kauwela ke kiʻekiʻe ka mahana o ka pā, a ʻoi aku ka maikaʻi o ka hana paʻa wai o MHEC ma mua o ka HPMC ma lalo o nā kūlana wela kiʻekiʻe. .

04. Pehea e hoʻoholo ai i ka maikaʻi o ka HPMC?

1) ʻOiai ʻaʻole hiki i ka keʻokeʻo ke hoʻoholo inā he maʻalahi ka HPMC e hoʻohana, a inā hoʻohui ʻia nā mea keʻokeʻo i ke kaʻina hana, e hoʻopilikia ʻia ka maikaʻi, akā ʻo ka hapa nui o nā huahana maikaʻi he keʻokeʻo maikaʻi, hiki ke hoʻopaʻi ʻia mai ka helehelena.
2) Ka hoʻouna ʻana i ka māmā: Ma hope o ka hoʻoheheʻe ʻana i ka HPMC i ka wai e hana i kahi colloid akaka, e nānā i kāna transmittance māmā. ʻOi aku ka maikaʻi o ka lawe ʻana i ka māmā, ʻoi aku ka liʻiliʻi o ka mea hiki ʻole ke hoʻoheheʻe ʻia, a ʻoi aku ka maikaʻi o ka maikaʻi.
Inā makemake ʻoe e hoʻoponopono pololei i ka maikaʻi o ka cellulose, ʻo ke ala ʻoi loa ka hilinaʻi o ka hoʻohana ʻana i nā lako ʻoihana i loko o kahi keʻena ʻoihana no ka hoʻāʻo. ʻO nā hōʻailona hoʻāʻo nui e pili ana i ka viscosity, ka nui o ka mālama ʻana i ka wai, a me ka ʻike lehu.

05. Pehea e ana i kaviscosity o ka cellulose ether?

ʻO ka viscometer maʻamau i ka mākeke home cellulose ʻo NDJ, akā i ka mākeke honua, hoʻohana pinepine nā mea hana like ʻole i nā ʻano hoʻokolohua viscosity like ʻole. ʻO nā mea maʻamau ʻo Brookfeild RV, Hoppler, a aia kekahi mau ʻokoʻa ʻike ʻokoʻa, i māhele ʻia i 1% solution a me 2% solution. ʻO nā viscometers ʻokoʻa a me nā ʻano ʻike ʻokoʻa e hopena pinepine i ka ʻokoʻa o nā manawa he nui a i ʻole nā ​​​​kini mau manawa i nā hopena viscosity.

06. He aha ka ʻokoʻa ma waena o ke ʻano hikiwawe HPMC a me ke ʻano hoʻoheheʻe wela?

ʻO nā huahana hikiwawe a HPMC e pili ana i nā huahana e hoʻopuehu koke i ka wai anuanu, akā pono e hoʻomaopopo ʻia ʻaʻole ka hoʻopuehu ʻana. Hoʻopili ʻia nā huahana koke me ka glyoxal ma ka ʻili a hoʻopuehu ʻia i ka wai anuanu, akā ʻaʻole lākou e hoʻomaka e hoʻoheheʻe koke. , no laila ʻaʻole i hana ʻia ka viscosity ma hope koke o ka hoʻopuehu ʻana. ʻOi aku ka nui o ka mālama ʻana i ka ʻili o ka glyoxal, ʻoi aku ka wikiwiki o ka hoʻopuehu ʻana, akā ʻoi aku ka lohi o ka viscosity, ʻoi aku ka liʻiliʻi o ka glyoxal, a me ka hope.

07. Hoʻohui pū me ka cellulose i hoʻololi ʻia
I kēia manawa, nui ka cellulose i hoʻololi ʻia a me ka cellulose i hoʻohui ʻia ma ka mākeke, no laila he aha ka hoʻololi a me ka hui?

Loaʻa pinepine kēia ʻano cellulose i nā waiwai i loaʻa ʻole i ka cellulose kumu a hoʻonui paha i kekahi o kāna mau waiwai, e like me: anti-slip, hoʻonui i ka manawa hāmama, hoʻonui ʻia kahi ʻōpala e hoʻomaikaʻi ai i ke kūkulu ʻana, a me nā mea ʻē aʻe. hoʻohana pū ʻia ʻO ka cellulose liʻiliʻi i hoʻohālikelike ʻia i mea e hōʻemi ai i nā kumukūʻai i kapa ʻia ʻo cellulose compound a i ʻole cellulose hoʻololi ʻia.
