HEMC ejiri rụọ ọrụ

Hydroxyethyl Methyl Cellulose (HEMC) bụ cellulose ether nke a na-ejikarị eme ihe na ụlọ ọrụ ihe owuwu dị ka ihe mgbakwunye na ihe ụlọ dị iche iche. HEMC na-enye ihe ndị a kapịrị ọnụ na ngwaahịa ihe owuwu, na-eme ka arụmọrụ ha dịkwuo mma na ịkwado usoro ihe owuwu. Nke a bụ nkọwapụta nke ngwa, ọrụ, na ntụle nke HEMC na-ewu:

1. Okwu Mmalite nke Hydroxyethyl Methyl Cellulose (HEMC) na-ewu

1.1 Nkọwa na isi mmalite

Hydroxyethyl Methyl Cellulose (HEMC) bụ ihe nrụpụta cellulose enwetara site n'imeghachi methyl chloride na alkali cellulose wee mechaa ethylene ngwaahịa ahụ na ethylene oxide. A na-ejikarị ya eme ihe dị ka onye na-ebu ibu, onye na-ejigide mmiri, na stabilizer na ngwa owuwu.

1.2 Ọrụ n'ihe eji arụ ọrụ

A maara HEMC maka njigide mmiri ya na ihe na-eme ka ọ dịkwuo mma, na-eme ka ọ dị mma maka ọtụtụ ihe owuwu ihe owuwu ebe rheology na-achịkwa na ịrụ ọrụ ka mma dị mkpa.

2. Ọrụ nke Hydroxyethyl Methyl Cellulose na-ewu

2.1 Njide mmiri

HEMC na-arụ ọrụ dị ka onye na-ejigide mmiri dị irè na ihe owuwu. Ọ na-enyere aka igbochi mmiri ozuzo ngwa ngwa, hụ na ngwakọta na-anọgide na-arụ ọrụ ruo ogologo oge. Nke a dị mkpa karịsịa na ngwaahịa simenti ebe idobe mmiri zuru oke dị oke mkpa maka hydration kwesịrị ekwesị.

2.2 Mgbanwe nke ukwuu na Rheology

HEMC na-eje ozi dị ka onye na-emepụta ihe na-emepụta ihe na-ewu ụlọ, na-emetụta viscosity na ihe na-asọpụta nke ihe ahụ. Nke a bara uru na ngwa dị ka adhesives tile, grouts, na ngwa agha, ebe rheology na-achịkwa na-eme ka arụmọrụ ngwa dịkwuo elu.

2.3 Emelitere ịrụ ọrụ

Mgbakwunye HEMC na ihe owuwu na-eme ka arụ ọrụ dịkwuo mma, na-eme ka ọ dị mfe ịgwakọta, gbasaa, na itinye. Nke a bara uru na ngwa dị iche iche, gụnyere plasta, nsụgharị, na ọrụ kọmpat.

2.4 Nkwụsi ike

HEMC na-enye aka na nkwụsi ike nke ngwakọta, na-egbochi ikewapụ na ịhụ na nkesa nke otu. Nkwụsi ike a dị mkpa n'ụdị usoro ebe idobe nkwụsi ike dị oke mkpa, dị ka ogige na-ebuli onwe ya.

3. Ngwa na-ewu

3.1 Tile Adhesives na Grouts

Na tile adhesives na grouts, HEMC na-eme ka njide mmiri dịkwuo mma, na-eme ka adhesion dịkwuo mma, ma na-enye viscosity dị mkpa maka ngwa ngwa. Ọ na-enye aka na n'ozuzu workability nke ngwaahịa ndị a.

3.2 Mortars na onyinye

A na-ejikarị HEMC eme ihe na ngwa ngwa ma na-emepụta usoro iji kwalite ịrụ ọrụ, gbochie ịla n'iyi, na ịkwalite nrapanye nke ngwakọta na mkpụrụ.

3.3 Ngwakọta na-ebuli onwe ya

N'ime ogige ndị na-edozi onwe ha, HEMC na-enyere aka n'ịkwado ihe ndị na-asọpụta chọrọ, na-egbochi nhazi, na ịhụ na elu dị larịị na larịị.

3.4 Ngwaahịa dabere na ciment

A na-agbakwunye HEMC na ngwaahịa simenti dị ka grouts, ihe mgbakwunye ihe, na plasta iji jikwaa viscosity, melite arụmọrụ, na ịkwalite arụmọrụ n'ozuzu ya.

4. Ntụle na ịkpachara anya

4.1 Usoro onunu ogwu na ndakọrịta

Ekwesịrị iji nlezianya chịkwaa usoro nke HEMC na usoro ihe owuwu iji nweta ihe ndị a chọrọ na-enweghị emetụta njirimara ndị ọzọ. Ndakọrịta na mgbakwunye na ihe ndị ọzọ dịkwa oke mkpa.

4.2 Mmetụta gburugburu

Mgbe ị na-ahọrọ ihe mgbakwunye ihe owuwu, gụnyere HEMC, ekwesịrị itinye nlebara anya maka mmetụta gburugburu ebe obibi ha. Nhọrọ na-adịgide adịgide na ebe obibi enyi na-adịwanye mkpa na ụlọ ọrụ ihe owuwu.

4.3 Nkọwa ngwaahịa

Ngwaahịa HEMC nwere ike ịdị iche na nkọwapụta, yana ọ dị mkpa ịhọrọ ọkwa kwesịrị ekwesị dabere na ihe achọrọ maka ngwa owuwu ahụ.

5. Nkwubi okwu

Hydroxyethyl Methyl Cellulose bụ ihe mgbakwunye bara uru na ụlọ ọrụ ihe owuwu, na-enye aka na njide mmiri, ịgbatị, na nkwụsi ike nke ihe owuwu dị iche iche. Ngwongwo ya dị iche iche na-eme ka ọ dị mma maka ngwa ngwa dị iche iche, na-eme ka arụ ọrụ na ịrụ ọrụ nke mmepụta ihe. Nleba anya nke ọma nke usoro onunu ogwu, ndakọrịta, na ihe gburugburu ebe obibi na-eme ka HEMC na-abawanye uru ya na ngwa ihe owuwu dị iche iche.
