Kongera kuramba no kurwanya kuvuza ibikoresho bishingiye kuri sima hamwe na HPMC

Intangiriro
Ibikoresho bishingiye kuri sima nibyingenzi mubwubatsi, gutanga ubusugire bwingenzi bwimiterere yinyubako, ibiraro, nibikorwa remezo. Ariko, ibyo bikoresho bikunze gucika no gukundwa kuramba kubera ibintu bitandukanye nibidukikije hamwe na robine. Kwishyira hamwe kw'ibyongeweho muri mivaementious ni ingamba zikorwa nazo zo kongera imitungo yabo. HydroxyPropyl MethylcellllAlose (HPMC) yagaragaye ko ashishikajwe no kuzamura imikorere y'ibikoresho bishingiye ku byaro.

Uburyo bw'ibikorwa
HPMC ni selile ether polymer izwiho kugumana namazi, kuzamura vicosity, hamwe numutungo wa firime. Iyo HPMC yongewe mu bikoresho bishingiye ku byaro, HPMC igira ingaruka ku nzira yo gukumira, imiterere ya pore, na rusange muri marikerix muburyo butandukanye:

Kugumana amazi no kugenzura hydration: HPMC yongera kugumana amazi muri sima, ni ingenzi kugirango habeho hydration ikwiye. Hydration ihagije ni ngombwa mugushinga kwa Kalisiga ya CALCUM (Csh) Gel, Bunder wibanze itanga imbaraga. Muguma amazi, HPMC iremeza ko harakomeje ko harakomeje mugihe kirekire, biganisha ku bidasanzwe kandi hakonja ibisanzwe.

Guhindura vicosity: Kwiyongera kwa HPMC byongera viste ya sima Paste, itezimbere ibikorwa kandi ituze yo kuvanga. Ibi ni ingirakamaro cyane mu kugabanya ishyano no kuva amaraso, aho amazi n'ibice byiza bitandukanijwe nivanga ryingenzi. Ivanga ihamye yemeza ko imirimo imwe ikwirakwizwa, ikagira uruhare mubikoresho bikomeye kandi bihanganye.

Gushiraho firime hamwe nuburyo bwo guhindura imiterere: HPMC ikora firime yoroshye, ihuriweho muri cemetion matrix. Iyi firime irashobora kurasa microckacks kandi izamura imibuto rusange yibikoresho. Byongeye kandi, HPMC igira ingaruka kumiterere ya pore kugabanya uburozi no gutunganya ikwirakwizwa rya pore. Imiterere ya Denser Imiterere igabanya abantu kugorana, bityo yongereranya ibintu bishingiye ku bidukikije nko guhagarika imizigo, ibitero by'imiti, no karubone.

Inyungu za HPMC mubikoresho bishingiye kuri sima
Isome rya HPMC mu bikoresho bishingiye ku byaro bitanga inyungu nyinshi zigaragara, cyane cyane kuzenguruka kuramba no kwarwara no kurwanya ibitaramo:

Kongera kuramba: Ubushobozi bwa HPMC bwo kugumana amazi no kugenzura ibyavuye mu buryo butaziguye igihe kirekire cyibikoresho bya sima bishingiye ku bya sima bishingiye ku bya sima bishingiye ku bya sima bishingiye ku bya sima bishingiye ku bya sima bishingiye ku bya sima bishingiye ku byaro bishingiye ku bya sima bishingiye ku bya sima bishingiye ku bya sima bishingiye ku bya sima bishingiye ku bya sima bishingiye ku byaro bishingiye ku bya sima bishingiye ku bya sima bishingiye ku bya sima bishingiye ku bya sima bishingiye ku byaro bishingiye ku bya sima bishingiye ku bya sima bishingiye ku byaro bishingiye ku bya sima. Mu kubungabunga amazi yuzuye no kugabanya uburozi, ibikoresho bivurwa bya HPMC byagaragaye ko birwanya inzira zitandukanye zibangamira ibintu bitandukanye nk'igitero cya SUlFate, Alkali-Silica Reaction (ASR), na chloride ion yinjira. Iyi iramba ryagutse risobanura igihe kirekire cyubuzima kandi kigabanya ibiciro byo kubungabunga imiterere.

Yongerewe Kurwanya: Gucika mu bikoresho bishingiye ku bya sima bishobora kubaho kubera agace ka plastike, gukama imyanda, imihangayiko, n'imitwaro ya mashini. HPMC ifasha kugabanya ibyo bibazo binyuze mu kugumana amazi no gushinga filmie. Mugukomeza ibintu bihagije mugihe cyo gukira, HPMC igabanya ibyago byo kugabanuka kwa plastike. Ingaruka zayo zo kugabanya ubunini bwa pore no kuzamura umubingo wa matrix nabyo bivuze ko ibikoresho bishobora kwikuramo no gukwirakwiza imihangayiko no gukwirakwiza imihangayiko, kugabanya amahirwe yo gukwirakwiza.

Igikorwa cyanonosowe hamwe no gusaba ibintu: Guhindura kuvanga vicosity na HPMC yorohereza gukora neza no gushyira mubikorwa ibikoresho bishingiye ku bya sima. Ibi ni ngombwa cyane mubikorwa byubwubatsi aho ubwitonzi bwo gukoresha no gusaba umuvuduko unegura. Ubushobozi bwa HPMC bwo gukumira gutandukanya no kuva amaraso byemeza ko kuvanga bivanze bikomeza kandi bihuriweho, bikaba ari ngombwa kugirango habeho ubuziranenge bwuzuye hamwe nubunyangamugayo bwubaka.

Porogaramu zifatika
HPMC ikoreshwa mu bicuruzwa bitandukanye bishingiye ku byaro bishingiye kuri sima, buri wese angukirwa n'imitungo yihariye:

Minisiteri na plaster: muri minisiteri na plaster itunganijwe, hpmc yongera ibikorwa, kurohama, no kurwanya. Iyi mitungo ningirakamaro kugirango igere ku buso bworoshye, burambye haba mububasha ndetse no hanze.

Ibigo byishyira hejuru: HPMC itezimbere imitungo itemba kandi ituze yo kwishyira hamwe, kwemeza kimwe, hejuru yubusa. Ibi ni ingirakamaro cyane kubisabwa hasi aho urwego nicyarambye kirakenewe.

Tile ashimishijwe: HPMC yongera ibirori no gufungura igihe cyo gutwikira, gutanga umwanya wakazi gahagije hamwe nibiranga bikomeye. Ibi biganisha ku kunoza kuramba no kurwanya imihangayiko yogosha, bishobora gutera amabati kumeneka cyangwa mu gihinja.

Ibikoresho byo gusana: Mu gusana minisiteri n'imboga, HPMC bigira uruhare mu bikorwa byiza kandi byagabanije kugabanuka kandi bigabanya kugabanuka, bituma gusana biramba kandi bidafite ubusa. Ibi ni ngombwa mugusubiza ubusugire bwinzego zangiritse.

Shotcrete kandi yateye beto: HPMC itezimbere ubumwe no gusohora amasasu, kugabanya gusubiramo no kwemeza umubano ukomeye hamwe na substrate. Ibi ni ngombwa cyane cyane mu kubaka no kubaka munsi y'ubutaka aho kuramba no kurwanya kuramba biranenga.

Isome rya HydroxyPropyl methylcellse (HPMC) mubikoresho bishingiye ku byaro bishingiye ku mutima no kurwanya guturika. Mugutezimbere amazi, guhinduranya vino, kandi bigakora firime zoroshye muri cement matrix, HPMC ikemura ibibazo byingenzi bijyanye na hydration, uburozi, hamwe no kugabana strotique. Izi nyungu ziganisha ku bikoresho biramba, guhanarwa, kandi byoroshye gukorana, bisobanura inzego ndende-zizewe. Nkuko inganda zubwubatsi zikomeje gushaka uburyo bwo kunoza imikorere no kuramba byibikoresho bishingiye ku bya sima, HPMC igaragara nkunguka agaciro hamwe ninyungu nyinshi zitandukanye.
