Hydroxypropyl Methylcellulose (HPMC) bụ ether cellulose na-abụghị ionic nke a na-ejikarị eme ihe n'ụlọ. Karịsịa n'etiti ndị na-abụghị shrinkage grouting ihe, uru nke HPMC bụ karịsịa ịrịba ama.
1. Melite arụmọrụ ihe owuwu
HPMC nwere ezigbo njide mmiri, nke na-enye ohere ka ihe na-adịghị emebi emebi na-enwe ike ịnọgide na-arụ ọrụ nke ọma na ịrụ ọrụ n'oge usoro ihe owuwu. Ọrụ njide mmiri nke HPMC na-eme ka mmiri na-ekesa n'otu n'otu n'ime slurry, na-egbochi mmiri ịpụ ngwa ngwa, si otú a na-egbochi elu nke slurry site na ihicha na mgbawa, na imeziwanye arụmọrụ na ịdị mma nke ihe owuwu.
2. Mma liquidity
HPMC nwere ike imeziwanye mmiri nke ihe ndị na-adịghị emebi emebi. Mgbe agbazechara ụmụ irighiri ihe HPMC na mmiri, ha ga-etolite ngwọta colloidal viscosity dị elu, na-abawanye viscosity nke slurry, na-eme ka slurry na-asọba nke ọma na nke kwụsiri ike, na-ezere ikewapụ na ọbara ọgbụgba. Nke a dị oke mkpa maka ịwụsa na njuputa nke slurry n'oge a na-ewu ụlọ, na-eme ka ịdị n'otu na ịdị mma nke ihe.
3. kwalite adhesion
HPMC nwere ezigbo adhesion, na-ekwe ka ndị na-adịghị ada ada grouting ihe ka mma rube isi na mkpụrụ n'elu. Ike njikọ a na-emewanyewanye nke ọma nwere ike imeziwanye nchikota ihe ma belata ihe ize ndụ nke ịdapụ ma ọ bụ ịgbawa mgbe e wuchara ya, si otú ahụ gbasaa ndụ ọrụ nke ụlọ ahụ.
4. Meziwanye nkwụsị mgbape
N'ihi na mmiri njigide na bonding Njirimara nke HPMC, ọ nwere ike budata melite mgbape eguzogide nke na-abụghị shrinkage grouting ihe. N'oge usoro ike siri ike, HPMC nwere ike ijikwa ọsọ mmeghachi omume nke ciment hydration nke ọma, belata okpomọkụ simenti hydration, gbochie mgbanwe olu nke mgbanwe okpomọkụ na-akpata, ma belata nrụgide shrinkage, si otú a na-ebelata ihe omume mgbawa.
5. Na-ebuli akụrụngwa akụrụngwa
HPMC nwere ike melite n'ibu Njirimara nke na-abụghị shrinkage grouting ihe. Mgbakwunye nke HPMC nwere ike imeziwanye ike mkpakọ na ike mgbanwe nke ihe ahụ, na-eme ka ihe ahụ gosipụta ịdịte aka na nkwụsi ike n'oge eji. Nke a dị mkpa karịsịa maka ihe owuwu ụlọ nke kwesịrị iguzogide ibu ibu na gburugburu nrụgide dị mgbagwoju anya.
6. Meziwanye ike
Ngwa nke HPMC nwere ike melite anwụ ngwa ngwa nke na-adịghị ada ada grouting ihe. HPMC nwere ike igbochi ikuku ngwa ngwa nke mmiri ma belata nhazi nke cracks n'oge usoro hydration nke ciment, si otú a na-egbu oge usoro ịka nká nke ihe. Na mgbakwunye, HPMC nwekwara ike welie ihe si ifriizi-mgbaza nguzogide na chemical corrosion eguzogide, ikwe ka ihe onwunwe nọgide na-enwe ọmarịcha arụmọrụ na obi ọjọọ gburugburu.
7. Meziwanye nchekwa ihe owuwu
Iji HPMC nwere ike melite nchekwa ihe owuwu. N'ihi na HPMC nwere ezigbo njide mmiri na nrapado, ọ nwere ike igbochi elu nke slurry ka ọ ghara ikpochapụ n'ihi ngwa ngwa nke mmiri na-ekpo ọkụ n'oge usoro ihe owuwu, si otú a na-ebelata oke ọrụ na ihe ize ndụ nchekwa nke ndị ọrụ ụlọ n'ihi ọgwụgwọ mgbawa. N'otu oge ahụ, ezigbo njem nke HPMC na-emekwa ka usoro ihe owuwu dị mfe ma dị irè karị, na-ebelata ihe ndị a na-ejighị n'aka na ihe owuwu na imeziwanye nchekwa ihe owuwu.
8. Environment arụmọrụ
HPMC bụ ihe na-adịghị egbu egbu, adịghị emerụ ahụ na ihe na-emebi emebi nke na-egbo mkpa nchekwa gburugburu ebe obibi nke ihe ụlọ ọgbara ọhụrụ. Ngwa ya na ihe ndị na-emepụta ihe na-adịghị emebi emebi ọ bụghị nanị na-eme ka arụ ọrụ nke ihe ahụ dịkwuo mma, ma na-ebelata mmetụta ọjọọ na gburugburu ebe obibi, n'ikwekọ na echiche nke mmepe mmepe.
Ngwa nke HPMC na-abụghị shrinkage grouting ihe nwere ọtụtụ uru. Ọ bụghị naanị na ọ na-emeziwanye arụmọrụ ihe owuwu ihe, mmiri mmiri na nrapado, kamakwa ọ na-eme ka mgbape mgbape nke ihe ahụ dịkwuo mma, ihe eji arụ ọrụ na ịdịte aka, ma nwee ezigbo arụmọrụ gburugburu ebe obibi. Uru ndị a na-eme ka HPMC bụrụ ihe dị mkpa na ihe dị mkpa nke ihe ndị na-adịghị emepụta ihe, na-akwalite mmepe na ọganihu nke teknụzụ ụlọ. N'ọdịnihu nyocha na mmepe na ngwa nke ihe owuwu ụlọ, HPMC ga-anọgide na-arụ ọrụ ya dị mkpa ma na-eweta ọtụtụ ihe ọhụrụ na ọganihu na ụlọ ọrụ ihe owuwu.
