Hydroxyethyl Methyl Cellulose Maka Mwube

Hydroxyethyl Methyl Cellulose, ma ọ bụ HEMC, bụ ngwakọta nke na-ewu ewu na ụlọ ọrụ mmepụta ihe. Ọ bụ polymer soluble mmiri nke ewepụtara na cellulose, a na-ejikarị ya eme ihe dị ka ihe na-eme ka ọ sie ike ma na-ejikọta ya na ngwa dị iche iche, dị ka ngwa agha, grouts, na plasta. A makwaara HEMC dị ka methyl hydroxyethyl cellulose (MHEC) ma ọ bụ methyl hydroxypropyl cellulose (MHPC) ma dị na ọkwa dị iche iche, nke ọ bụla nwere njirimara na njirimara.

N'isiokwu a, anyị ga-enyocha ihe onwunwe na uru nke HEMC na ngwa ya na ụlọ ọrụ mmepụta ihe.

Njirimara nke HEMC

HEMC bụ ntụ ntụ ọcha ma ọ bụ na-acha ọcha na-enweghị isi na enweghị ụtọ. Ọ na-agbaze na mmiri oyi ma na-etolite ngwọta doro anya ma ọ bụ dị ntakịrị. Viscosity nke ngwọta na-adabere na ntinye nke HEMC na ogo nke nnọchi (DS), nke bụ ọnụọgụ nke ọnụ ọgụgụ nke hydroxyl dị iche iche nke methyl na hydroxyethyl na-anọchi anya na mkpokọta hydroxyl dị na cellulose molecule.

HEMC nwere ọtụtụ ihe a na-achọsi ike na-eme ka ọ bụrụ ihe mgbakwunye dị mma na ihe owuwu:

  1. Njide mmiri: HEMC nwere ike ịmịnye mmiri ma jide ya na ngwakọta, na-ebelata mmiri dị mkpa na igbochi nkwụsị na mgbawa.
  2. Thickening: HEMC na-abawanye viscosity nke ngwakọta, na-eme ka ọrụ rụọ ọrụ na igbochi nkewa.
  3. Njide: HEMC na-arụ ọrụ dị ka ihe nkedo, na-ejikọta ngwakọta ọnụ ma na-eme ka adhesion na elu.
  4. Nhazi ihe nkiri: HEMC nwere ike ịmepụta ihe nkiri dị mkpa n'elu, na-eme ka mmiri na-eguzogide mmiri na ịdịte aka.

Ngwa nke HEMC na Construction

A na-eji HEMC eme ihe n'ọtụtụ ebe na ụlọ ọrụ ihe owuwu dị ka ihe mgbakwunye na ihe dị iche iche. Ụfọdụ ngwa ya na-ahụkarị gụnyere:

  1. Mortar: A na-agbakwunye HEMC na ngwa agha iji kwalite ịrụ ọrụ, belata ọchịchọ mmiri, na ịbawanye njide mmiri. Ọ na-eme ka ike njikọ na ịdịte aka nke ngwa agha ahụ dịkwuo elu.
  2. Tile Adhesives: A na-eji HEMC eme ihe na nkedo tile iji meziwanye wetting na belata nhụpụ, na-eme ka adhesion na ịdịte aka nke taịl nile.
  3. Grouts: A na-agbakwunye HEMC na grouts iji meziwanye arụmọrụ, belata mbelata na mgbawa, ma kwalite nkwụsị mmiri.
  4. Stucco na Plasta: A na-eji HEMC eme ihe na stucco na plasta iji meziwanye arụmọrụ, belata mgbawa, na ịbawanye njide mmiri. Ọ na-emekwa ka ike njikọ na ịdịte aka nke ihe ahụ dịkwuo elu.
  5. Ogige ndị na-edozi onwe ha: A na-agbakwunye HEMC na ogige ndị na-eme ka ọ dịkwuo mma iji mee ka mmiri na-asọba na ọkwa dị elu, belata nkwụsị na mgbawa, ma kwalite nkwụsị mmiri.

Uru HEMC na Nrụpụta

HEMC na-enye ọtụtụ uru na ihe owuwu, gụnyere:

  1. Ịrụ ọrụ nke ọma: HEMC na-eme ka arụ ọrụ nke ihe arụ ọrụ dịkwuo mma, na-eme ka ọ dị mfe ijikwa ma tinye ya n'ọrụ.
  2. Mbelata mmiri chọrọ: HEMC na-ebelata oke mmiri dị mkpa na ngwakọta, na-eme ka ike na ịdịte aka nke ihe ahụ dịkwuo mma.
  3. Mmụba njide mmiri: HEMC na-eme ka njigide mmiri nke ihe dị mma, na-egbochi nkwụsị na mgbawa ma na-eme ka ogologo oge ha dịkwuo elu.
  4. Enwekwu ike: HEMC na-eme ka adhesion nke ihe na-eme ka ọ dịkwuo elu, na-eme ka ogologo oge na ike ha dịkwuo elu.
  5. Mmanya mmiri na-eguzogide: HEMC na-emepụta ihe nkiri dị mkpa n'elu, na-eme ka mmiri na-eguzogide mmiri na ịdịte aka.

Mmechi

HEMC bụ ihe dị iche iche na-enye ọtụtụ uru na ụlọ ọrụ ihe owuwu. Ngwongwo ya pụrụ iche na-eme ka ọ bụrụ ihe mgbakwunye dị mma na ihe dị iche iche, dị ka ngwa agha, grouts, na plasta. Site n'ịkwalite ịrụ ọrụ, ibelata ọchịchọ mmiri, na ịkwalite njide mmiri na adhesion, HEMC na-eme ka ike, ịdịte aka, na ịrụ ọrụ nke ihe owuwu ahụ dịkwuo mma.
