Hydroxypropyl Methyl Cellulose (HPMC) bụ polymer vasatail nke na-achọta ngwa dị ukwuu n'ime ihe ụlọ dị iche iche n'ihi njirimara ya pụrụ iche. Nke a na-enweta cellulose ether sitere na cellulose eke ma na-eji ya eme ihe n'ọtụtụ ebe na ngwaahịa ihe owuwu maka njide mmiri ya, njupụta, na ike ijikọta ya.
1. Okwu Mmalite nke Hydroxypropyl Methyl Cellulose (HPMC)
Hydroxypropyl Methyl Cellulose bụ ether cellulose na-abụghị ionic nke a na-enweta site n'ịgwọ cellulose eke na propylene oxide na methyl chloride. Ọ bụ soluble na mmiri na-etolite a uzo, viscous ngwọta. Ụdị dịgasị iche iche nke HPMC na-ebilite site n'ikike ya igbanwe njirimara rheological, njide mmiri, na adhesion na ihe owuwu.
2. Ngwa na Mortar
2.1. Njide mmiri
A na-ejikarị HPMC eme ihe na ngwa ngwa iji kwalite njide mmiri. Ọdịdị hydrophilic ya na-enye ya ohere ịbanye na ijide mmiri, na-egbochi ihicha ngwa ngwa. Ngwongwo a na-eme ka arụ ọrụ ka mma, ogologo oge ịtọlite na mma mmachi na mkpụrụ osisi.
2.2. Ịba ụba na njikwa Rheology
The mgbakwunye nke HPMC na ngwa agha formulations inye na-achọsi ike ndim Njirimara, emetụta rheological omume nke ngwakọta. Nke a dị oké mkpa maka ịdị mfe nke ngwa na imezu ihe achọrọ na ngwa ngwa.
2.3. Adhesion emelitere
Ịgbakwunye HPMC na ngwa agha na-eme ka adhesion na elu dị iche iche, na-enye aka na ike zuru oke na ogologo oge nke ihe owuwu ahụ. Nke a dị mkpa karịsịa na ngwa dịka nrụnye tile seramiiki.
3. Ngwa na Tile Adhesives na Grouts
3.1. Ịrụ ọrụ emelitere
Adhesives tile na-enwekarị HPMC iji kwalite arụmọrụ na oge oghere. Polima na-eme ka nrapado na-anọgide na-arụ ọrụ ruo ogologo oge, na-enye ohere maka ntinye nke tile kwesịrị ekwesị na-enweghị ihicha oge.
3.2. Mbelata mbelata
HPMC na-enye aka na njirimara mgbochi sagging nke tile adhesives. Nke a dị mkpa mgbe ị na-etinye taịlị n'elu kwụ ọtọ, ebe ọ na-egbochi taịlị ndị ahụ ịdaba n'ihu nrapado ahụ.
3.3. Nguzogide mgbawa na Grouts
N'ime usoro grout, HPMC na-enyere aka igbochi mgbawa site n'inye mgbanwe na ibelata shrinkage. Nke a bara uru karịsịa na gburugburu ebe mgbanwe okpomọkụ nwere ike imetụta ihe ụlọ.
4. Ngwa na plasta
4.1. Ịrụ ọrụ na mgbasawanye nke ọma
A na-agbakwunye HPMC n'ụdị plasta iji kwalite arụmọrụ na mgbasawanye. Polymer na-enyere aka nweta ngwa ngwa nke plasta na-adịwanye nro ma na-agbanwe agbanwe.
4.2. Nguzogide mgbawa
Yiri ọrụ ya na grouts, HPMC na-enye aka na mgbawa mgbawa na plasta. Ọ na-emepụta ihe nkiri na-agbanwe agbanwe nke na-anabata mmegharị okike nke ihe ụlọ, na-ebelata ohere nke mgbawa.
5. Ngwa dị n'ime nhazi nke onwe
5.1. Njikwa usoro
Na ogige ndị na-edozi onwe ha, a na-eji HPMC chịkwaa ihe na-asọpụta na nhazi ọkwa. Polymer na-ahụ maka nkesa otu ma na-enyere aka ịnọgide na-enwe ọkpụrụkpụ nke ogige ahụ n'ofe ngwa ahụ.
5.2. Adhesion emelitere
HPMC na-eme ka adhesion nke ogige ndị na-ebuli onwe ya elu na ihe dị iche iche, na-enye njikọ siri ike na nke na-adịgide adịgide. Nke a dị oké mkpa maka ịrụ ọrụ ogologo oge nke elu larịị.
6. Nkwubi okwu
Hydroxypropyl Methyl Cellulose na-arụ ọrụ dị mkpa n'ịkwalite arụmọrụ nke ihe ụlọ dị iche iche. Ngwa ya na ngwa ngwa, ihe nrapado tile, grouts, plasta, na ogige ndị na-edozi onwe ya na-egosipụta ike ya na ịdị irè ya na ụlọ ọrụ ihe owuwu. Ngwongwo pụrụ iche nke HPMC, gụnyere njide mmiri, nkwụsi ike, na mma nrapado, na-enye aka n'ịdị mma, ogologo oge, na ịrụ ọrụ nke ihe ụlọ ndị a. Ka ụlọ ọrụ ihe owuwu na-aga n'ihu na-etolite, HPMC na-anọgide na-abụ isi ihe na-emepụta ihe ụlọ dị elu na nke dị elu.
