Ni ubuhe bwoko butandukanye bwa mortila yumye? Gukoresha ifu ya latex ishobora gukurwamo

Urusenda rw'ifu rwumye ruvuga ibintu bifite ifu cyangwa ifu bikozwe mu kuvanga ibintu byose, ibintu bitagira umwimerere bikoreshwa muri sima, n'ibindi byakuwemo byakamishijwe kandi bigashyirwa mu gipimo runaka. Ni ibihe bintu bikunze gukoreshwa muri sima yumye? Urusenda rw'ifu rwumye muri rusange rukoresha sima ya Portland nk'ibikoresho bikoreshwa muri sima, kandi ingano y'ibikoresho bikoreshwa muri sima muri rusange ingana na 20% kugeza 40% by'urusenda rw'ifu rwumye; Ibice byinshi bito bivanze ni umucanga wa quartz kandi bisaba ingano nini yo gusukurwa mbere nko kumisha no gupima kugira ngo ingano n'ubwiza byabyo byujuje ibisabwa muri formula; Hari igihe ivu ry'umukungugu, ifu y'ibishishwa, nibindi nabyo byongerwaho nk'ibivanze; Ibivanze muri rusange bikoreshwa mu rugero ruto, kuva kuri 1% kugeza kuri 3%, ariko bigira ingaruka zikomeye. Akenshi bitoranywa hakurikijwe ibisabwa muri formula y'ibicuruzwa kugira ngo byongere ubushobozi bwo gukora, gushyiramo ibice, imbaraga, gushonga, no kurwanya ubukonje bwa sima.

Ni ubuhe bwoko bw'inyongeramusaruro z'ifu yumye zikoreshwa cyane?

Ifu ya latex ishobora kongera gushonga

Ifu ya latex ishobora kongera gukoreshwa ishobora kongera imiterere ikurikira mu ifu yumye:

① Uburyo amazi abikwa n'ubushobozi bwo gukora bwa mortironi nshya ivanze;

② Imikorere y'imibanire y'ibice bitandukanye by'ibanze;

③ Uburyo bworoshye bwo guhindura no guhindura imiterere ya mortilage;

④ Ingufu n'ubumwe biramba;

⑤ Ubudahangarwa bw'umubiri;

⑥ Ubushobozi bwo kwihangana;

⑦ Ubugari (kudashobora guhindagurika).

Ishyirwa mu bikorwa ryaifu ya latex ishobora kongera gushongamu gikoresho cyo gusigwa gikozwe mu buryo bworoshye, mu gikoresho gifunga amatafari ya ceramic, mu buryo bwo gukingira inkuta zo hanze, no mu bikoresho byo hasi byigenga byagaragaje umusaruro mwiza.

Uburyo bwo kubika no gukurura amazi

Ibintu bigabanya amazi birimo cyane cyaneeteri za selulose, eteri za sitashi, n'ibindi. Eteri ya selulose ikoreshwa mu ifu yumye ahanini ni eteri ya methyl hydroxyethyl cellulose (MHEC) na eteri ya hydroxypropyl methyl cellulose (HPMC).

Umuti ugabanya amazi

Akamaro k'ibanze k'ibintu bigabanya amazi ni ukugabanya ikiguzi cy'amazi muri mortilage, bityo bikanongera imbaraga zayo zo gukanda. Ibintu by'ingenzi bigabanya amazi bikoreshwa muri mortilage yumye birimo casein, igikoresho gikuraho amazi gishingiye kuri naphthalene, melamine formaldehyde condensate, na aside polycarboxylic. Casein ni superplasticizer nziza cyane, cyane cyane kuri mortilage yoroheje, ariko bitewe n'imiterere yayo karemano, ubwiza bwayo n'igiciro cyayo bikunze guhinduka. Ibintu bigabanya amazi bya Naphthalene series bikunze gukoreshwa β- Naphthalenesulfonic acid formaldehyde condensate.

Agakoresho gakingira amaraso

Hari ubwoko bubiri bwa coagulants: accelerator na retarder. Ibintu bifasha kwihutisha imiterere no gukomera kwa mortil, kandi calcium formate na lithium carbonate birakoreshwa cyane. Aluminate na sodium silicate nabyo bishobora gukoreshwa nk'ibintu bifasha kwihutisha imiterere. Retarder ikoreshwa mu kugabanya imiterere no gukomera kwa mortil, kandi aside tartarique, aside citric n'umunyu wayo, ndetse na gluconate byakoreshejwe neza.

Umuti udakoreshwa n'amazi

Ibintu bigabanya amazi birimo ahanini ibintu bya polymer nka chloride y'icyuma, ibintu bya silane y'umwimerere, umunyu wa aside irike, fibre ya polypropylene, na styrene butadiene rubber. Ibikoresho bigabanya amazi bya chloride y'icyuma bifite ingaruka nziza zo kwirinda amazi, ariko bikunze kwangirika kw'ibyuma n'ibice by'icyuma. Umunyu wa kalisiyumu udashonga uva mu mikorere y'umunyu wa aside irike hamwe na iyoni za kalisiyumu mu gice cya sima wishyira ku nkuta z'imiyoboro y'amaraso, bigira uruhare mu kuziba imyenge no gutuma inkuta z'imiyoboro y'amaraso ziba ubuso butoshye, bityo bikagira uruhare mu kwirinda amazi. Igiciro cy'ibi bicuruzwa ni gito, ariko bifata igihe kirekire kuvanga sima neza n'amazi.

fibre

Insinga zikoreshwa mu gusya ifu yumye zirimo insinga z'ibirahure zirwanya alkali, insinga za polyethylene (fiber ya polypropylene), insinga za polyvinyl alcohol zikomeye kandi zifite modulus nyinshi (fiber ya polyvinyl alcohol),fibre y'ibiti, n'ibindi. Ikoreshwa cyane ni imigozi ikomeye kandi ifite modulus polyvinyl alcohol hamwe n'imigozi ya polypropylene. Imigozi ikomeye kandi ifite modulus polyvinyl alcohol ifite imikorere myiza kandi ihendutse ugereranije n'imigozi ya polypropylene itumizwa mu mahanga. Imigozi ikwirakwira mu buryo butari bumwe kandi bungana muri sima, kandi ihuzwa neza na sima kugira ngo hirindwe ko habaho imiyoboro mito, bigatuma moduli ya mortilage iba nini, bityo ikaba ifite imikorere idapfa amazi kandi irwanya cyane imiyoboro. Uburebure ni milimetero 3-19.

Umusesenguzi

Muri iki gihe, ibikoresho byo gusukura ifu bikoreshwa mu ifu yumye ahanini ni polyols na polysiloxanes. Gukoresha ibikoresho byo gusukura ifu ntibishobora gusa guhindura ingano y'ibice by'umukara, ahubwo binagabanya kugabanuka. Mu mikoreshereze ifatika, kugira ngo kunoze imikorere yuzuye, inyongera nyinshi zigomba gukoreshwa icyarimwe. Muri iki gihe, ni ngombwa kwita ku ngaruka zihuriweho hagati y'inyongera zitandukanye. Byongeye kandi, ni ngombwa kandi kwita ku mubare w'inyongera zongewemo. Ni nke cyane ku buryo zigaragaza ingaruka z'inyongera; Ni nyinshi cyane, hashobora kubaho ingaruka mbi.
