MHEC ni iki? Uruhare rw'ingenzi mu miterere ya mortar na irangi

Uko inganda z’ubwubatsi n’amatapi zikomeza gutera imbere, icyifuzo cy’inyongeramusaruro nziza zinoza ireme ry’ibicuruzwa, imikorere myiza, no kuramba cyariyongereye cyane. Muri izo nyongeramusaruro,Selirulose ya Methyl Hydroxyethyl (MHEC)yabaye imwe muri eteri za cellulose z'ingenzi zikoreshwa mu bikoresho byumye bivanze, kole z'amatafari, putty yo ku rukuta, ibicuruzwa bya gypsum, n'irangi rishingiye ku mazi.

MHEC ihabwa agaciro kubera ubushobozi bwayo bwo kubika amazi neza, ubushobozi bwo gukuba, kongera ubushobozi bwo gukora, no kugenzura uburwayi bw'imitsi. Ifasha abakora ibikoresho by'ubwubatsi n'amabara yujuje ibisabwa mu mikorere, mu gihe inoza imiterere y'ikoreshwa ryabyo ku ba rwiyemezamirimo n'abakoresha ba nyuma.

Iyi nkuru irasuzuma icyo MHEC ari cyo, uko ikorwa, imiterere yayo y'ingenzi, n'impamvu igira uruhare runini mu gukora irangi rya none.

Gusobanukirwa MHEC

MHEC ni iki?

Methyl Hydroxyethyl Cellulose (MHEC) ni ether ya cellulose itari ionic ikomoka kuri cellulose karemano, ikunze kuva mu dupira tw’ipamba twatunganyijwe cyangwa mu duti.

Binyuze mu nzira yo kugenzura etherification, selulose ihindurwa mu buryo bwa shimi binyuze mu gushyiramo:

  • Amatsinda ya Methyl
  • Amatsinda ya Hydroxyethyl

Izi mpinduka zihindura cellulose idashonga ikayihindura polymeri ishonga mu mazi ifite ubushobozi bwiza bwo gukurura no kubika amazi.

 

MHEC ikomoka mu muryango umwe na:

Muri izi ether za cellulose, MHEC ikunzwe cyane mu bwubatsi kubera ko ifata amazi neza kandi ihura neza na sima na gypsum.

Imiterere ya Chimique ya MHEC

Uruti rw'umugongo rwa selulosi rurimo utunyangingo twa anhydroglucose dusubiramo.

Mu gihe cyo gukora:

  • Amatsinda amwe ya hydroxyl asimburwa n'andi ya methyl.
  • Amatsinda amwe ya hydroxyl asimburwa n'andi ya hydroxyethyl.

Iri hinduka ritanga:

  • Gushonga kw'amazi kwarushijeho kuba kwiza
  • Kongera ubushobozi bwo guhagarara neza mu bushyuhe
  • Imikorere myiza yo gukurura
  • Gukora neza cyane

Igipimo cyo gusimbuza gishingira ahanini ku mikorere y'ibicuruzwa n'uko bikwiranye n'ikoreshwa ryabyo.

Uburyo bwo gukora MHEC

Intambwe ya 1: Gutegura selulosi

Selulosi isukuye iva mu ipamba cyangwa mu giti iratoranywa ikanonosorwa.

Intambwe ya 2: Guhindura alkali

Selulose ivurwa na sodium hydroxide kugira ngo ikoreshwe ahantu hakora reactive.

Intambwe ya 3: Guhindura imiterere y'amazi

Selulose ikora ikora ikoresheje:

  • Methyl chloride
  • Oxyde ya etileni

Ibi bwinjiza amatsinda ya methyl na hydroxyethyl mu miterere ya molekile.

Intambwe ya 4: Kutagira aho bibogamiye

Alkali nyinshi ntizikoreshwa.

Intambwe ya 5: Gukaraba no Gusukura

Imyanda n'ibisigazwa by'imiti birakurwaho.

Intambwe ya 6: Kumisha no gusya

Umusaruro usukuye urumishwa hanyuma ugasya ukavamo ifu nziza ikwiriye gukoreshwa mu nganda.

Imitungo y'ingenzi ya MHEC

Kubika amazi neza cyane

Imwe mu miterere y'agaciro ka MHEC ni ubushobozi bwayo bwo kubika amazi muri sisitemu zishingiye kuri sima.

Ibyiza birimo:

  • Gutanga amazi meza kuri sima
  • Kongera imbaraga mu iterambere
  • Kugabanuka kw'imyanya
  • Igihe cyo gufungura cyagutse

Ingaruka zo gushonga

MHEC yongera ubukana bw'amaraso kandi igatanga imiterere ihamye y'imitsi yo mu maraso.

Ibi bifasha:

  • Irinde ivangura
  • Kunoza uburinganire
  • Ongera imiterere y'ikoreshwa

Kunoza ubushobozi bwo gukora

MHEC ikora imiterere y'umusemburo woroshye kandi uryoshye woroshye gukoresha.

Ibyiza birimo:

  • Kugabanuka k'imbaraga z'abakozi
  • Imikorere myiza yo gukurura amashanyarazi
  • Irangi ryiza ry'ubuso

Gutunganya filime

MHEC igira uruhare mu ikorwa rya filimi zirinda impanuka zinoza imikorere y'ipamba.

Ituze

Ibisubizo bya MHEC biguma bihamye mu gihe cy'ubushyuhe bwinshi n'imiterere ya pH.

Impamvu MHEC ari ingenzi mu gushushanya imisemburo ya mortar

Udupira tw’ubu bwoko bw’imyunyungugu dukoreshwa mu buryo bw’umwimerere (dry-vange mortiers) dukenera imiterere yihariye y’imikorere.

MHEC ifasha kugera kuri izi ntego.

MHEC mu byuma bikometse ku matafari

Kole zo mu bwoko bwa tile ziri mu nzego zikomeye zikoreshwa muri MHEC.

Kubika Amazi

MHEC irinda gutakaza amazi vuba muri:

  • Beto
  • Imbaho ​​za sima
  • Ubuso bw'amabuye

Ibi bituma sima ikomeza kumera neza.

Kongera igihe cyo gufungura

Abashyiraho amatafari babona umwanya uhagije wo gushyiramo amatafari.

Ibyiza birimo:

  • Gutunganya neza amatafari
  • Kugabanya imyanda
  • Ubwiza bw'inyubako burushijeho kuba bwiza

Kunoza uburyo bwo gufata neza

MHEC iteza imbere umubano ukomeye hagati ya:

  • Kole y'amatafari
  • Ubuso bw'amatafari
  • Inzu ntoya

Imikorere yo kurwanya Kudashyira mu gaciro

Ku bijyanye no gukoresha amatafari yo ku rukuta, MHEC irushaho kunoza uburyo bwo kudacika kw'amatafari.

Amatafari aguma mu mwanya wayo neza nyuma yo kuyashyiraho.

MHEC muri Wall Putty

Puti yo ku rukuta isaba uburyohe bwiza kandi buhamye.

MHEC itanga:

  • Gukwirakwiza byoroshye
  • Kubungabunga amazi neza
  • Imiterere myiza yo gusya
  • Ubudahangarwa bw'imipfundo
  • Gufata neza kw'umubiri

Kubera iyo mpamvu, ubuso burushaho kuba bwiza kandi bugakomeza.
