Gukoresha HPMC muri sima ya sima

Intangiriro

Hydroxypropyl Methylcellulose (HPMC) ni ether ya selile idafite ionic ikomoka kuri selile naturel. Yabaye inyongera yingirakamaro mubikorwa byubwubatsi, cyane cyane mugukora sima ya sima. HPMC yongerera imbaraga za minisiteri, igira uruhare mu kunoza imikorere, gufata amazi, gufatira hamwe, nimbaraga za mashini.

Ibigize nibyiza bya HPMC

HPMC ikomatanyirizwa hamwe na etherification ya selile hamwe na methyl chloride na oxyde ya propylene. Polimeri yavuyemo irangwa nubushobozi bwayo bwo hejuru bwamazi, ibintu bihindura ubwiza, hamwe nubushobozi bwo gukora film. Ibi biranga HPMC inyongera nziza yo guhindura imiterere ya rheologiya yibikoresho bishingiye kuri sima.

Inyungu za HPMC muri Cement Mortar

1. Kunoza imikorere

Imwe mu nyungu zibanze za HPMC muri sima ya sima nubushobozi bwayo bwo kuzamura imikorere. HPMC ikora nk'amavuta hagati ya sima, igabanya ubukana no kwemerera gukoreshwa neza. Iterambere ryimikorere ryorohereza gukwirakwiza no kuringaniza minisiteri, ngombwa kugirango umuntu arangize kimwe.

2. Kongera amazi meza

HPMC itezimbere cyane ubushobozi bwo gufata amazi ya sima ya sima. Kubika amazi ni ngombwa mugihe cyo gukira kuko bitanga amazi ahagije ya sima, biganisha ku iterambere ryiza. Mu kugumana amazi, HPMC irinda gukama imburagihe kandi igabanya ibyago byo guturika no kugabanuka muri minisiteri.

3. Kwiyongera kwa Adhesion

Adhesion ningirakamaro kuburambe no gukora bya sima ya sima. HPMC yongerera imbaraga imiterere ya minisiteri mu kunoza imbaraga zayo zo guhuza ibice bitandukanye, nk'amatafari, amabuye, hamwe na beto. Uku kwiyongera kwiyemeza ko minisiteri ikomeza kuba ntamakemwa mugihe cyibidukikije.

4. Imbaraga za mashini

Kwinjiza HPMC muri sima ya sima bigira uruhare mubukanishi bwayo. Muguhindura uburyo bwo kuyobora no kunoza microstructure ya minisiteri, HPMC ifasha kugera kumbaraga zo guhonyora no guhindagurika. Iterambere ningirakamaro mubikorwa byubaka aho ubushobozi bwo kwikorera imitwaro bireba.

Uburyo bwibikorwa bya HPMC muri Cement Mortar

1. Guhindura Viscosity

HPMC ihindura ubwiza bwimvange ya minisiteri, bigatuma irushaho guhuriza hamwe kandi byoroshye kubyitwaramo. Iminyururu ya polymer ya HPMC ikorana na molekile zamazi, ikora imiterere isa na gel yongerera ubwiza bwicyiciro cyamazi. Ingaruka ya gelation ifasha mukubungabunga ubutinganyi bwa minisiteri kandi ikarinda gutandukanya ibice.

Kubika Amazi

Imiterere ya hydrophilique ya HPMC ituma ikurura kandi ikagumana amazi menshi. Iyo wongeyeho kuri sima, HPMC ikora inzitizi igabanya umuvuduko wamazi. Uku kumara igihe kinini kumazi bituma amazi ahoraho ya sima, aringirakamaro mugutezimbere imbaraga nigihe kirekire muri minisiteri.

3. Gushiraho Filime

Iyo yumye, HPMC ikora firime ikomeza, yoroheje muri materique. Iyi firime yongerera umubano hagati ya sima hamwe na agregate, igateza imbere ubusugire rusange bwa minisiteri. Iyi filime kandi igira uruhare mu kurwanya minisiteri yo kwinjira mu mazi no mu kirere.

Ibitekerezo bifatika mugukoresha HPMC

1. Umubare

Igipimo cyiza cya HPMC muri sima ya sima iratandukanye bitewe na progaramu yihariye hamwe nibintu byifuzwa. Mubisanzwe, ibipimo biri hagati ya 0.1% na 0.5% kuburemere bwa sima. Umubare munini urashobora gukenerwa kubisabwa bidasanzwe, nko kwipimisha minisiteri cyangwa gufatira tile.

2. Kuvanga inzira

Uburyo bwo kuvanga neza nibyingenzi kugirango habeho gukwirakwiza HPMC muri minisiteri. Kuvanga byumye bya HPMC nibindi bikoresho byifu mbere yo kongeramo amazi birasabwa. Ibi byemeza ko polymer itatanye kandi igakorwa iyo ihuye namazi.

3. Guhuza nibindi Byongeweho

HPMC irahujwe nurwego runini rwinyongera zikoreshwa muri sima ya sima, nka superplasticizers, yihuta, na retarders. Nyamara, ni ngombwa gukora ibizamini byo guhuza kugirango harebwe niba ingaruka ziterwa ninyongeramusaruro nyinshi zitagira ingaruka mbi kumikorere ya minisiteri.

Porogaramu ya HPMC muburyo butandukanye bwa sima Mortars

1. Amashanyarazi

Muri tile yometseho, HPMC itezimbere igihe cyo gufungura, kunyerera kunyerera, nimbaraga zo gufatira hamwe. Gufata neza amazi byemeza ko ibifatika bikomeza gukora mugihe kirekire, bigatuma hashyirwaho tile neza.

2. Gutanga na Mortars

Kumurongo wa pompe na plaster, HPMC itanga akazi keza kandi igabanya ibyago byo kugabanuka. Gutezimbere neza hamwe no gufata amazi bigira uruhare mukurangiza neza, kuramba.

3 Kwishyira hejuru

Kwiyoroshya-minisiteri yungukirwa nubwiza-bwo guhindura ibintu bya HPMC, byemeza ubuso bumwe, urwego. Polimeri ifasha kubungabunga amazi ya minisiteri mugihe irinda gutandukana no kuva amaraso.

4. Gusana Mortars

Mu gusana minisiteri, HPMC yongerera imbaraga insimburangingo iriho kandi igateza imbere imiterere yubukorikori bwahantu hasanwe. Ubushobozi bwo gufata amazi ya HPMC butuma gukira neza no kuramba.

HPMC ninyongera itandukanye yongerera cyane imikorere ya sima ya sima. Inyungu zayo, zirimo kunoza imikorere, gufata amazi, gufatira hamwe nimbaraga za mashini, bituma iba ikintu cyingenzi mubikorwa bitandukanye byubwubatsi. Gusobanukirwa nuburyo bwibikorwa bya HPMC no gusuzuma ibintu bifatika nka dosiye noguhuza nibyingenzi mugutezimbere imikoreshereze yabyo muri sima. Mugihe inganda zubwubatsi zikomeje gutera imbere, ikoreshwa rya HPMC rishobora kwaguka, gutwara iterambere mu bwiza no kuramba kwibikoresho bishingiye kuri sima.
