Hydroxypropyl methylcellulose (HPMC) bụ polymer vasatail nke a na-ejikarị n'ụdị ọrụ dị iche iche, gụnyere ihe owuwu, ebe ọ na-achọta ngwa na gypsum grouts. Ngwakọta a na-arụ ọrụ dị mkpa n'ịkwalite arụmọrụ nke usoro grout, na-enyere aka melite arụmọrụ, adhesion na arụmọrụ zuru ezu.
Okwu Mmalite nke Hydroxypropyl Methylcellulose (HPMC)
1. Chemical Ọdịdị na mejupụtara
HPMC bụ ihe sitere na cellulose, polymer eke dị na mgbidi cell osisi.
Otu hydroxypropyl na methyl dị na nhazi ya na-enye HPMC ihe ndị pụrụ iche.
Lelee ihe mejupụtara kemịkalụ n'ụzọ zuru ezu.
2. Njirimara anụ ahụ
Njirimara nke solubility na mmiri na ihe mgbaze ndị ọzọ.
Mgbanwe arọ molekụla na mmetụta ha na arụmọrụ.

Ngwa nke HPMC na gypsum grouting
1. Nchịkọta nke gypsum grouting
Okwu mmalite na gypsum dị ka ihe eji ewu ụlọ.
Mkpa nke grouting na-ewu oru ngo.
Ụdị Gypsum Grout na ngwa ha.
2. Ọrụ HPMC na gypsum grouting
Ihe njide mmiri na-egbochi mmiri mmiri ngwa ngwa.
Ọganihu ka mma na ịdị mfe nke ngwa.
Kwalite adhesion maka nsonaazụ njikọ kacha mma.
Jikwaa oge nhazi nke gypsum grout.
3. Atụmatụ nhazi
Usoro ọgwụgwọ HPMC kacha mma maka usoro grout dị iche iche.
Ndakọrịta na mgbakwunye ndị ọzọ na admixtures.
Mmetụta na akụrụngwa akụrụngwa nke gypsum gwọrọ.
Uru nke Iji HPMC na Gypsum Grout
1. Melite ịrụ ọrụ
Mmetụta na-agbanwe agbanwe na flowability nke grout ngwakọta.
Na-ebelata nkewa na nsogbu ọbara ọgbụgba.
Kwesịrị ekwesị maka elu kwụ ọtọ na elu.
2. Njide mmiri na ịtọ akara oge
Mkpa ọ dị ijide mmiri iji gbochie ihicha akaghi aka.
Jikwaa oge ntọala iji gboo mkpa ihe owuwu dị iche iche.
Mmetụta na mmepe ike.
3. Meziwanye adhesion
Na-akwalite adhesion siri ike na mkpụrụ dị iche iche.
Belata mgbawa mgbawa na ntụpọ ndị ọzọ.
Ndakọrịta na ihe dị elu dị iche iche.
Ihe ịma aka na echiche
1. Ihe gbasara gburugburu ebe obibi
Mmetụta okpomọkụ na iru mmiri na arụmọrụ HPMC.
Atụmatụ maka ịnagide ihe ịma aka na ọnọdụ dị oke njọ.
2. njikwa mma
Mkpa mmesi obi ike dị na HPMC grouting.
Usoro ule na ụkpụrụ.
Ọdịnihu na ihe ọhụrụ
1. Nnyocha na mmepe
Nnyocha na-aga n'ihu iji melite usoro HPMC.
Apụta omume na adigide na enyi na gburugburu ebe obibi grouting ngwọta.
na ngwụcha
Ka ụlọ ọrụ ihe owuwu na-aga n'ihu na-etolite, mkpa HPMC na-emeziwanye arụmọrụ nke gypsum grouts nwere ike ịba ụba, na-enyere aka nweta ihe owuwu na-adịgide adịgide na nke ọma.
