ʻO Methyl ethyl hydroxyethyl cellulose (MEHEC) kahi ʻano o ka cellulose ether e ʻike i nā noi like ʻole ma nā ʻoihana like ʻole ma muli o kāna mau waiwai kūʻokoʻa. ʻO kēia pūhui he mea ia o ka cellulose, he polymer kūlohelohe i loaʻa i loko o nā paia o nā mea kanu. Hoʻopili ʻia ka MEHEC ma o kahi kaʻina hana kemika e pili ana i ka etherification o cellulose me nā hui methyl, ethyl, a me hydroxyethyl. Hōʻike ka hui hopena i ka paʻa ʻana o ka wai maikaʻi loa, mānoanoa, hana kiʻiʻoniʻoni, a me nā waiwai hoʻokuʻu, e hoʻohana pono ai i ka nui o nā noi.
1. Nā pena a me nā uhi:
Hoʻohana maʻamau ʻia ʻo MEHEC ma ke ʻano he rheology modifier a me ka mānoanoa i nā pena wai a me nā uhi. ʻO kona hiki ke hoʻomalu i ka viscosity a pale i ka hoʻonohonoho ʻana i ka puaʻa he mea nui ia i nā hana no nā pena o loko a me waho, nā primers, a me nā uhi. Hoʻomaikaʻi ʻo MEHEC i nā waiwai noi o nā pena ma ka pale ʻana i ka spattering, hōʻoia i ka uhi ʻokoʻa, a me ka hoʻonui ʻana i ka brushability.
2. Nā mea hana kūkulu:
I ka ʻoihana kūkulu, hoʻohana ʻia ʻo MEHEC i nā huahana like ʻole e like me nā mea hoʻopili paʻa ciment-based tile, grouts, a me nā renders. Ma ka hāʻawi ʻana i ka mālama ʻana i ka wai a me ka hana i kēia mau mea, hōʻoia ʻo MEHEC i ka hydration kūpono o nā ʻāpana sima, hoʻomaikaʻi i ka hoʻopili ʻana, a hoʻemi i ka sagging a i ʻole slumping i ka wā o ka noi. Hoʻohui ʻia, hoʻonui ia i ka kūlike a me ka pumpability o nā ʻano cementitious, e maʻalahi iā lākou ke lawelawe.
3.Adhesives a me Sealants:
He mea hoʻohui koʻikoʻi ka MEHEC i ka hoʻokumu ʻana i nā mea hoʻopili wai a me nā sealants. Hoʻomaikaʻi ia i ka tack, viscosity, a me ka manawa wehe o nā adhesives, e hoʻomaʻamaʻa i ka hana hoʻopaʻa maikaʻi ʻana ma nā substrates like ʻole. I nā sealants, kōkua ʻo MEHEC e hoʻokō i ka extrudability kūpono, thixotropy, a me ka hoʻopili ʻana, e hōʻoia ana i ka hoʻopaʻa ʻana o nā hono a me nā āpau i ke kūkulu ʻana a me nā noi automotive.
4. Nā huahana mālama pilikino:
Ma muli o kāna mau mea hana kiʻiʻoniʻoni a me ka mānoanoa, hoʻohana ʻia ʻo MEHEC i nā ʻano mālama pilikino a me nā huahana cosmetic. Hiki ke loaʻa iā ia i loko o ka hoʻokumu ʻana o nā ʻaila, nā lotions, nā shampoos, a me nā gels ʻauʻau, kahi e hoʻonui ai i ke ʻano, kūpaʻa, a me nā waiwai moisturizing. Hoʻohana pū ʻo MEHEC ma ke ʻano he mea hoʻomaha no nā ʻāpana paʻa i loko o nā hana mālama pilikino, pale i ka sedimentation a me ka hōʻoia ʻana i ka hāʻawi like ʻana.
5. Nā lāʻau lapaʻau:
Hoʻohana ʻo MEHEC ma ke ʻano he mea hoʻopaʻa, mānoanoa, a me ka mea hoʻopaʻa i loko o nā ʻano lāʻau lapaʻau e like me nā papa, nā ʻaila, a me nā mea hoʻomaha. ʻO kona hiki ke hoʻomalu i ka viscosity a me ka hoʻomaikaʻi ʻana i nā waiwai kahe e hōʻoia i ka hāʻawi like ʻana i ka lāʻau lapaʻau a me ka hoʻohālikelike ʻana. I loko o nā kumuhana kumuhana, hāʻawi ʻo MEHEC i kahi ʻano maʻemaʻe a me ka momona ʻole i ka wā e hoʻonui ai i ka hoʻopili ʻana o nā mea hana i ka ʻili.
6. ʻOihana meaʻai a me nā mea inu:
ʻOiai ʻoi aku ka liʻiliʻi o ka hoʻohālikelike ʻana i nā noi ʻē aʻe, hoʻohana ʻia ʻo MEHEC i kekahi manawa i ka ʻoihana meaʻai a me ka mea inu ma ke ʻano he mea mānoanoa a hoʻopaʻa. Loaʻa paha ia i loko o kekahi mau meaʻai e like me nā meaʻai, nā lole, a me nā mea inu, kahi e hoʻomaikaʻi ai i ke ʻano, ka waha, a me ka paʻa o ka papa me ka hoʻololi ʻole ʻana i ka ʻono a me ka ʻala.
7. ʻOihana ʻaila a me ke kinoea:
Loaʻa ka MEHEC i ka hoʻohana ʻana i nā wai wili a me nā slurries sima i hoʻohana ʻia i ka ʻoihana aila a me ke kinoea. Kōkua ia i ka mālama ʻana i ka viscosity wai, hoʻopaneʻe i nā ʻāpana paʻa, a pale i ka nalowale o ka wai i ka wā o ka hana ʻana. ʻO nā wai i hoʻonui ʻia MEHEC e hōʻoia i ka paʻa pono o ka luawai, ka lubrication, a me ka wehe ʻana i nā ʻoki drill, e hāʻawi ana i ka holomua holoʻokoʻa o nā hana wili.
8. ʻOihana lole lole:
Hoʻohana ʻia ʻo MEHEC i ka paʻi lole a me nā kaʻina hana hoʻoluʻu ma ke ʻano he mānoanoa a me ka rheology modifier no ka paʻi ʻana i nā pastes a me nā ʻauʻau wai. Hoʻomaikaʻi ia i ka kūlike a me nā waiwai kahe o ka paʻi paʻi ʻana, e hōʻoiaʻiʻo ana i ka waiho pololei ʻana o nā kala ma luna o nā substrate textile. Kōkua pū ka MEHEC i ka pale ʻana i ke koko kala a me ka hoʻomaikaʻi ʻana i ka ʻoi o nā ʻano paʻi.
9. Nā mea hana ʻoihana ʻē aʻe:
ʻIke ʻo MEHEC i nā noi like ʻole i nā ʻoihana e like me nā mea holoi, hana pepa, a me nā seramika. I loko o nā mea holoi, hoʻonui ia i ka paʻa a me ka rheology o nā ʻano wai, ʻoiai i ka hana pepa, hoʻomaikaʻi ia i ka ikaika pepa a me ka paʻa ʻana o nā mea hoʻopiha a me nā mea hoʻohui. I nā seramika, hana ʻo MEHEC ma ke ʻano he mea hoʻopili a me ka rheology hoʻololi i nā slurries seramika, e hoʻomaʻamaʻa i ka hana ʻana a me ka hana ʻana.
ʻO ka methyl ethyl hydroxyethyl cellulose (MEHEC) he cellulose ether maʻamau me nā noi ākea ma waena o nā ʻoihana like ʻole. ʻO kona hui pū ʻana o nā waiwai, me ka mānoanoa, ka paʻa ʻana o ka wai, ka hana kiʻiʻoniʻoni, a me nā mea hiki ke hoʻokuʻu ʻia, e lilo ia i mea hoʻohui waiwai i nā hana hoʻohui mai nā pena a me nā uhi i nā huahana mālama pilikino, nā lāʻau lapaʻau, a ma waho. Hāʻawi ʻo MEHEC i ka hoʻomaikaʻi ʻana i ka hana o ka huahana, ka hana ʻana i ka maikaʻi, a me ka ʻike mea hoʻohana hope ma nā noi like ʻole, a laila e pāʻani ana i kahi kuleana koʻikoʻi i nā ʻāpana ʻoihana.
