Mmetụta Dị Mmiri
Na Wall Pinty, mmetụta ndị dị na Hec na-eme ka p upty nwere viscosity nwere viscosity, si otú a na-eme ka ọrụ owuwu. Ezi mmetụta nke na-eme ka ọ bụrụ na etinyere ma ọ bụrụ na etinyere ya na mgbidi na-enweghị nkọ ma ọ bụ mkpokọta.

Meziwanye njide mmiri
Ngwongwo na-ejigide mmiri nke Putty dị oke mkpa maka owuwu ya. HEC nwere ike igbu egbu mmiri ma hụ na pubty ahụ zuru oke n'oge usoro ịgwọ ọrịa, si otú ahụ na-eme ka ike na ịdịgide ahụ na-emekwu ihe. Karịsịa na gburugburu akọrọ, njikọta mmiri nke hec nwere ike meziwanye arụmọrụ nke Putty ma gbochie ya ihicha.

Meziwanye ihe owuwu
Ngwa nke hec na Putity nwere ike ime ka ịdị ire ụtọ na ewepụghị nke ihe ahụ, na-eme ka ihe dị ka mmiri owuwu. N'otu oge ahụ, n'ihi na hec nwere ike kwụsịtụ oghere ahụ n'ime Putty ma gbochie ha idozi, puetty ahụ na-enwe arụmọrụ kwụsiri ike n'oge nchekwa.

Melite ogo elu
HEC na-arụ ọrụ nke na-eme nke ọma na Putty na Putty, nke na-enye ohere ka o touti iji mepụta elu dị larịị ma sie ike mgbe ị na-agwọ. N'elu elu a abụghị naanị ájá, kamakwa ọ na-enye ezigbo ihe ịchọ mma, na-enye ntọala dị mma maka arụmọrụ eserese na-esote.

Mgbidi Mgbidi
Na mgbidi Putty, na-agbakwụnye hec nwere ike imezi arụmọrụ owuwe ihe owuwu na elu nke Putty. Iji maa atụ, n'otu ọrụ, na-agbakwunye 0.2% hec gbatịrị oge ọrụ nke Pubty site n'ihe dị ka nkeji iri atọ, na elu nke putty ahụ dị larịị, na-enye ezigbo mma maka ịchọ mma.

ciment nke onwe
Na ntinye nke ciment nke onwe onye, ​​hec nwere ike ime ka viocosity na mmiri nke slurry, na-ekwe ka ciment ka o nwee ike ime ka aru di nma na udiri onwe ya. Dịka ọmụmaatụ, n'otu ebe dị larịị, na-agbakwunye 0.3% hecwoy ka mma mmiri na ike onwe onye nke ciment slurry. Mgbe owuwu, ala dị nro, enweghịkwa ihe na-adịghị mma.

Dịka mgbakwunye ọtụtụ ọrụ, hydroxyethyth cellose egosila dị mma na-arụpụta na ciment na mgbidi. Ogwe mmiri ya, ebe nchekwa mmiri, ma mee ka arụmọrụ dị mma dị mma ma mee ka ọ dịkwuo mma owuwu ihe, kamakwa nke ukwuu na-emewanye ike ngọngọ na ịdị ogologo. Na mmepe na-aga n'ihu nke teknụzụ akụrụngwa, hec ga-arụ ọrụ dị mkpa na ngwa ọgwụ n'ọdịnihu.
