Mmetụta Hydroxypropyl Methyl Cellulose dị na Mortar Dry na Mwube

Hydroxypropyl methyl cellulose (HPMC) bụ nke a na-ejikarị eme ihe n'ụdị ngwa agha akọrọ na ụlọ ọrụ ihe owuwu n'ihi ihe ndị pụrụ iche ya. Nke a bụ ụfọdụ mmetụta HPMC na ngwa ngwa akọrọ:

1. Njide mmiri: Otu n'ime isi ọrụ HPMC na ngwa ngwa akọrọ bụ ime ihe dị ka onye na-ejigide mmiri. HPMC na-emepụta ihe nkiri nchebe gburugburu akụkụ ciment, na-egbochi mmiri ngwa ngwa n'oge ngwakọta na ngwa. Ndogide mmiri a gbatịkwuru na-eme ka arụ ọrụ, nrapanye, na hydration nke ngwa agha ahụ, na-ebute nkwalite njikọ na ịdịte aka.
2. Nrụ ọrụ emelitere: HPMC na-enye ezigbo ọrụ iji kpoo ngwa agha nkụ site n'ịkwalite nkwụsi ike na mgbasa ya. Ọ na-eme ka ọ dị mfe ịgwakọta, na-ebelata ịdọrọ, ma na-amụba ịdị n'otu, na-enye ohere maka ngwa dị nro na mkpuchi ka mma na mkpụrụ. Nke a na-arụ ọrụ nke ọma na-eduga n'ịbelata ọnụ ahịa ọrụ yana ịkwalite mmepụta ihe na saịtị ihe owuwu.
3. Adhesion emelitere: HPMC na-eme ka nrapanye nke ngwa agha akọrọ na ihe dị iche iche, gụnyere konkịtị, masonry, wood and metal. Site n'ịmepụta ihe nkiri na-agbanwe agbanwe ma na-ejikọta ọnụ, HPMC na-eme ka ike nkekọ dị n'etiti ngwa agha na mkpụrụ, na-ebelata ihe ize ndụ nke delamination, cracking, ma ọ bụ nkwụsịtụ ka oge na-aga. Nke a na-ebute ọrụ owuwu ndị a pụrụ ịdabere na ya na nke na-adịte aka.
4. Mbelata Mbelata na mgbawa: HPMC na-enyere aka belata mbelata na mgbawa ngwa ngwa akọrọ site na imezi njikọ ya na ibelata ikuku mmiri n'oge ọgwụgwọ. Ọnụnọ nke HPMC na-akwalite hydration otu na mgbasa nke urughuru, na-ebute mbelata shrinkage na nkwụsi ike akụkụ nke ngwa agha ahụ. Nke a na-enye aka na njedebe zuru oke na iguzosi ike n'ezi ihe nke ihe owuwu emechara.
5. Oge nhazi a na-achịkwa: Enwere ike iji HPMC chịkwaa oge nhazi nke ngwa ngwa akọrọ site na ịmegharị kinetics hydration ya. Site n'ịgbanwe ọdịnaya na ọkwa HPMC, ndị ọrụ ngo nwere ike ịhazi oge ntọala ka dabara na ihe achọrọ na ọnọdụ gburugburu ebe obibi. Mgbanwe a na-enye ohere maka ịhazi nhazi ọrụ ka mma yana ịrụ ọrụ nke ọma n'ihe owuwu.
6. Enwekwukwa Rheology: HPMC na-eme ka njirimara reological nke ngwa ngwa akọrọ dị ka viscosity, thixotropy, na àgwà mkparị. Ọ na-eme ka ọ na-aga n'ihu na-arụ ọrụ na-arụ ọrụ n'okpuru ọnọdụ ngwa dị iche iche, na-eme ka ọ dị mfe nke mgbapụta, spraying, ma ọ bụ troweling. Nke a na-arụpụta ihe ndị ọzọ na-edoghị anya na nke mara mma na mgbidi, ala, ma ọ bụ n'uko ụlọ.
7. Ọdịnaya emelitere: HPMC na-akwalite ịdịte aka nke ngwa agha akọrọ site n'ịbawanye nguzogide ya na ihe gburugburu ebe obibi dị ka cycles-thaw cycles, ingress ingress, and chemical ikpughe. Ihe nkiri nchebe nke HPMC hibere na-enyere aka mechie elu ngwa agha ahụ, na-ebelata porosity, efflorescence, na mmebi ka oge na-aga. Nke a na-eduga n'ọrụ ihe owuwu na-adịte aka yana nhazi nke ọma.

mgbakwunye nke Hydroxypropyl methyl cellulose (HPMC) na ngwa ngwa akọrọ na-enye ọtụtụ uru, gụnyere njigide mmiri dị mma, ịrụ ọrụ, nrapanye, ịdịte aka, na arụmọrụ. Ọdịmma ya na ịdị irè ya na-eme ka ọ bụrụ mgbakwunye bara uru na ngwa ihe owuwu dị iche iche, gụnyere ndozi tile, plasta, nrụpụta, na grouting.
