Ingaruka za Hydroxyethyl Methyl Cellulose (HEMC) mugushiraho igihe muburyo bwa beto

Gushiraho igihe cya beto nikintu cyingenzi kigira ingaruka kumyubakire niterambere. Niba igihe cyo gushiraho ari kirekire, birashobora gutuma iterambere ryubaka buhoro kandi byangiza ubwiza bwa beto; niba igihe cyo gushiraho ari gito cyane, birashobora gukurura ingorane mubwubatsi bufatika kandi bigira ingaruka kubikorwa byumushinga. Kugirango uhindure igihe cyo gushiraho beto, ikoreshwa ryimvange ryabaye uburyo busanzwe mubikorwa bya kijyambere.Hydroxyethyl Methyl Cellulose (HEMC), nkibisanzwe byahinduwe na selile, bikoreshwa cyane mubintu bifatika kandi bishobora kugira ingaruka kuri rheologiya, kubika amazi, kugena igihe nibindi bintu bya beto.1. Ibintu shingiro bya HEMC

HEMC ni selile yahinduwe, mubisanzwe ikorwa muri selile naturel binyuze muri Ethylation na methylation reaction. Ifite amazi meza, kubyimba, kubika amazi hamwe na gelling, bityo ikoreshwa cyane mubwubatsi, gutwikira, imiti ya buri munsi nindi mirima. Muri beto, HEMC ikoreshwa cyane mubyimbye, kubika amazi no kugenzura imiterere ya rheologiya, bishobora kunoza imikorere ya beto, kongera gufatira hamwe no kumara igihe cyo gushiraho.

2. Ingaruka za HEMC mugihe cyo gushiraho beto
Gutinda gushiraho igihe
Nkibikomoka kuri selile, HEMC irimo umubare munini wamatsinda ya hydrophilique mumiterere yayo ya molekile, ishobora gukorana na molekile zamazi kugirango ikore hydrata ihamye, bityo bidindiza gahunda yo gutanga sima kurwego runaka. Hydration reaction ya sima nuburyo nyamukuru bwo gukomera gukomeye, kandi kongeramo HEMC birashobora guhindura igihe cyagenwe binyuze muburyo bukurikira:

Gufata neza amazi: HEMC irashobora kunoza cyane gufata amazi ya beto, kugabanya umuvuduko wamazi wamazi, no kongera igihe cyo gufata amazi ya sima. Binyuze mu gufata amazi, HEMC irashobora kwirinda gutakaza amazi menshi, bityo igatinda kubaho kwambere no kurangiza.

Kugabanya ubushyuhe bwamazi: HEMC irashobora kubuza kugongana nogutwara reaction ya sima mukwongera ubwiza bwa beto no kugabanya umuvuduko wimikorere ya sima. Igipimo cyo hasi cya hydration gifasha gutinza igihe cyo gushiraho beto.

Guhindura imiterere: HEMC irashobora guhindura imiterere ya rheologiya ya beto, ikongerera ubwiza bwayo, kandi igakomeza paste ya beto mumazi meza mugihe cyambere, ikirinda ingorane zubwubatsi ziterwa na coagulation ikabije.

Impamvu
Ingaruka yaHEMCmugushiraho igihe ntabwo bifitanye isano rya hafi na dosiye yacyo, ariko nanone bigira ingaruka kubindi bintu byo hanze:

Uburemere bwa molekuline n'urwego rwo gusimbuza HEMC: Uburemere bwa molekile n'urwego rwo gusimbuza (urugero rwo gusimbuza Ethyl na methyl) ya HEMC bigira uruhare runini mubikorwa byayo. HEMC ifite uburemere buke bwa molekuline hamwe nu rwego rwo hejuru rwo gusimburwa mubisanzwe birashobora gukora imiterere ikomeye y'urusobekerane, byerekana gufata neza amazi no kubyimba ibintu, bityo ingaruka zo gutinda kugena igihe ni ngombwa.

Ubwoko bwa sima: Ubwoko butandukanye bwa sima bufite igipimo cyamazi meza, bityo ingaruka za HEMC kuri sisitemu zitandukanye za sima nazo ziratandukanye. Isima isanzwe ya Portland ifite umuvuduko mwinshi, mugihe sima imwe yubushyuhe buke cyangwa sima idasanzwe ifite umuvuduko muke, kandi uruhare rwa HEMC muribwo buryo rushobora kugaragara cyane.

Ibidukikije: Ibidukikije nkubushyuhe nubushuhe bigira uruhare runini mugihe cyagenwe cya beto. Ubushyuhe bwo hejuru buzihutisha hydration reaction ya sima, bikavamo igihe gito cyo gushiraho, kandi ingaruka za HEMC mubushyuhe bwo hejuru zirashobora gucika intege. Ibinyuranye, mubushyuhe buke, ibidukikije byo gutinda kwa HEMC birashobora kugaragara cyane.

Kwishyira hamwe kwa HEMC: Ubwinshi bwa HEMC bugena mu buryo butaziguye urugero rwingaruka zayo kuri beto. Ubushuhe bwinshi bwa HEMC burashobora kongera cyane gufata amazi hamwe na rheologiya ya beto, bityo bikadindiza neza igihe cyagenwe, ariko HEMC ikabije irashobora gutera amazi mabi ya beto kandi ikagira ingaruka kumikorere yubwubatsi.

Ingaruka ya synergiste ya HEMC hamwe nibindi bivanga
Ubusanzwe HEMC ikoreshwa hamwe nibindi bivanze (nk'igabanya amazi, retarders, nibindi) kugirango ihindure byimazeyo imikorere ya beto. Hamwe nubufatanye bwabadindiza, gushiraho gutinda kwa HEMC birashobora kurushaho kunozwa. Kurugero, ingaruka zo guhuza ibintu bimwe na bimwe bidindiza nka fosifate hamwe nisukari ivangwa na HEMC birashobora kongera cyane igihe cyo gushiraho beto, ikwiranye nimishinga idasanzwe mubihe bishyushye cyangwa bisaba igihe kirekire cyo kubaka.

3. Izindi ngaruka za HEMC kumiterere ifatika

Usibye gutinza igihe cyo gushiraho, HEMC igira n'ingaruka zingenzi kubindi bintu bya beto. Kurugero, HEMC irashobora kunoza amazi, kurwanya amacakubiri, gukora pompe no kuramba kwa beto. Mugihe uhindura igihe cyagenwe, ingaruka zo kugumana no gufata amazi ya HEMC zirashobora kandi gukumira neza gutandukanya cyangwa kuva amaraso ya beto, kandi bikazamura ubwiza rusange nuburinganire bwa beto.

Hydroxyethyl methylcellulose (HEMC) irashobora gutinza neza igihe cyo gushiraho beto binyuze mu gufata neza amazi, kubyimba no kugarura ingaruka. Urwego rwingaruka za HEMC rwibasiwe nibintu nkuburemere bwa molekile, urugero rwo gusimburwa, ubwoko bwa sima, guhuza imiti hamwe nibidukikije. Mugenzuye neza igipimo nigipimo cya HEMC, igihe cyo gushiraho kirashobora kongerwa neza mugihe harebwa imikorere yubwubatsi bwa beto, kandi imikorere nigihe kirekire cya beto irashobora kunozwa. Ariko, gukoresha cyane HEMC birashobora kandi kuzana ingaruka mbi, nkamazi mabi cyangwa hydratiya ituzuye, bityo rero igomba gukoreshwa ubwitonzi ukurikije ibikenewe mubuhanga.
