Ọrụ Polycarboxylate Superplasticizer na Grouting Mortars

Polycarboxylate superplasticizers (PCEs) bụ ihe na-arụ ọrụ dị elu nke na-ebelata mmiri a na-ejikarị na-ewu ụlọ, gụnyere n'ime ngwa agha. Ha pụrụ iche chemical Ọdịdị na Njirimara-eme ka ha dị irè na melite workability na arụmọrụ nke grouting ihe. Nke a bụ ọrụ bụ isi nke polycarboxylate superplasticizers n'ịkwakọta ngwa agha:

1. Mbelata mmiri:

• Ọrụ: Ọrụ bụ isi nke polycarboxylate superplasticizers bụ mbelata mmiri. Ha nwere ike ịgbasa akụkụ ciment, na-enye ohere maka mbelata dị ukwuu na mmiri nke grout na-enweghị ịchụ àjà ọrụ. Nke a na-ebute ike dị elu na ịdịte aka nke ihe grouted.

2. Enwerekwa ike ịrụ ọrụ:

• Ọrụ: PCEs na-eme ka arụ ọrụ nke ngwa agha grouting na-arụ ọrụ site n'inye ọkwa dị elu na ịdị mfe nke ntinye. Nke a dị mkpa karịsịa na ngwa ebe grout kwesịrị ịbanye ma mejupụta oghere dị warara ma ọ bụ oghere.

3. Mbelata nkewa na Ọbara:

• Ọrụ: Polycarboxylate superplasticizers na-enyere aka belata nkewa na ọchịchọ ọbara ọgbụgba nke ihe mgbụsị akwụkwọ. Nke a dị oke mkpa maka ị nweta nkesa otu ihe siri ike, igbochi mmezi, na ịhụ na arụmọrụ na-aga n'ihu.

4. Rheology emelitere:

• Ọrụ: PCEs na-agbanwe njirimara rheological nke ngwa agha grouting, na-emetụta ọsọ ha na viscosity ha. Nke a na-enye ohere ijikwa ihe dị mma n'oge ngwa, na-eme ka o kwekọọ n'ụdị a chọrọ ma mejupụta oghere nke ọma.

5. Adhesion emelitere:

• Ọrụ: Polycarboxylate superplasticizers na-enye aka n'ịkwado mmachi n'etiti grout na mkpụrụ. Nke a dị mkpa iji hụ na njikọ siri ike na igbochi okwu dị ka debonding ma ọ bụ delamination.

6. Mmepe Ike mmalite:

• Ọrụ: PCE nwere ike ịkwalite mmepe ike mmalite na ngwa agha grouting. Nke a bara uru na ngwa ebe achọrọ ntọala ngwa ngwa na uru ike, dị ka n'ime ihe ndị a kpụrụ akpụ ma ọ bụ nrụzi nhazi.

7. Ndakọrịta na mgbakwunye:

• Ọrụ: Polycarboxylate superplasticizers na-adakọkarị na ihe mgbakwunye ndị ọzọ a na-ejikarị eme ihe n'ịgba ngwa agha, dị ka ndị na-eme ngwa ngwa, ndị na-azụ azụ, na ndị na-enye ikuku. Nke a na-enye ohere maka mgbanwe n'ịkwado njirimara nke grout na ihe achọrọ kpọmkwem.

8. Mmetụta gburugburu ebe obibi na-adịgide adịgide yana dị ala:

• Ọrụ: A maara PCE maka arụmọrụ ha n'ibelata ọdịnaya mmiri ka ha na-arụ ọrụ. Nke a na-enye aka n'ịrụ ọrụ ụlọ na-adịgide adịgide na gburugburu ebe obibi site n'ibelata mkpokọta carbon akara nke metụtara mmepụta na njem ciment.

9. Elu Flowability na Grouts na-ebuli onwe ya:

• Ọrụ: N'ime grouts na-ebuli onwe ya elu, polycarboxylate superplasticizers dị oke mkpa maka iru eru nke achọrọ na-enweghị nkewa. Nke a na-eme ka grout ahụ nwee ọkwa onwe ya ma na-enye ihe dị nro, ọbụnadị elu.

10. Mgbasa ozi ọma:

Atụmatụ:

• Usoro onunu ogwu na Ngwakọta Ngwakọta: Ngwọta kwesịrị ekwesị nke polycarboxylate superplasticizer na-adabere na nhazi ngwakọta, ụdị ciment, yana ihe achọrọ. Ọ dị mkpa ịgbaso ndụmọdụ ndị nrụpụta.
• Nnwale ndakọrịta: Mepụta ule ndakọrịta iji hụ na superplasticizer dakọtara na ihe ndị ọzọ dị na ngwakọta grout, gụnyere ciment, mgbakwunye, na ihe mgbakwunye.
• Ogo nke ciment: Ogo nke ciment a na-eji na ngwa agha grouting nwere ike imetụta arụmọrụ nke superplasticizer. Iji ciment dị elu dị mkpa iji nweta nsonaazụ kacha mma.
• Ọnọdụ ngwa: Tụlee ọnọdụ okpomọkụ, iru mmiri, na ọnọdụ gburugburu ebe obibi ndị ọzọ mgbe a na-eji ngwa agha grouting iji hụ na arụmọrụ kwesịrị ekwesị.

Na nchịkọta, polycarboxylate superplasticizers na-arụ ọrụ dị mkpa n'ịkwalite arụmọrụ nke ngwa agha grouting site na imeziwanye arụmọrụ, ibelata ọdịnaya mmiri, na ịkwalite mma nrapado na mmepe ike mmalite. Ojiji ha na-enye aka na arụmọrụ na nkwado nke omume ihe owuwu.
