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, a na-ejikwa ya eme ihe n'ịrụpụta ihe maka njide mmiri, 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
Ịtinye 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.
