Nigute viscosity ya selulose ether igira ingaruka kumikorere ya gypsum mortar?

Ether ya selulose ikoreshwa nkibintu byongewe mubikoresho byubwubatsi bitewe nubushobozi bwabo bwo guhindura imiterere yimiterere nubukanishi bwibikoresho. By'umwihariko, akenshi binjizwa muri gypsum ya minisiteri kugirango batezimbere amazi, gukora no gufatana. Nyamara, ingaruka zihariye za selile ya ether viscosity ku mikorere ya gypsum mortar ntirasobanurwa neza. Uru rupapuro rusubiramo ibitabo biriho kuriyi nsanganyamatsiko kandi ruganira ku ngaruka zishobora guterwa na selile ya ether viscosity ku miterere ya minisiteri ya gypsumu.

Ethers ya selile ni polymer zishonga mumazi zikomoka kuri selile, polymer karemano iboneka murukuta rwibimera. Bikunze gukoreshwa nkibibyimbye, binders na stabilisateur mubikorwa bitandukanye byinganda zirimo ibiryo, amavuta yo kwisiga, imiti nibikoresho byubwubatsi. Mu bwubatsi, akenshi binjizwa muri minisiteri kugirango barusheho gukora neza, gukomera no kuramba.

Gypsumu ni imyunyu ngugu isanzwe igizwe na calcium sulfate dihydrate. Ikoreshwa cyane mubwubatsi kubintu birwanya umuriro hamwe nijwi hamwe nubushyuhe bwumuriro. Gypsum mortar isanzwe ikoreshwa nka primer kurukuta rwa stucco no hejuru, kimwe no kurangiza imirimo yo kubaka akuma.

Iyo selile ya selile yongewe kuri gypsum mortar, irashobora guhindura imiterere ya rheologiya ivanze. Rheologiya ni ubushakashatsi bwo guhindura ibintu no gutembera kw'ibikoresho munsi ya stress. Imyitwarire yimyitwarire ya gypsumu irashobora kurangwa nubwiza bwayo, ni igipimo cyo kurwanya imigezi. Ubukonje bwa minisiteri buterwa nimpamvu nyinshi, zirimo ubwoko nubunini bwa selile ya selile, ingano yingingo nogukwirakwiza gypsumu, nigipimo cyamazi na sima.

Hejuru ya viscosity selulose ethers ikunda kugira uruhare runini kumyitwarire yimyitwarire ya gypsum kuruta eferi yo hasi. Kurugero, ubushakashatsi bwerekanye ko kongera hydrocypropylmethylcellulose (HPMC) hejuru ya viscosity hydrocypropylmethylcellulose (HPMC) bishobora kongera ububobere bwuruvange kandi bikazamura imikorere yabyo, mugihe HPMC ifite ubukonje buke ntacyo ihindura kumyitwarire ya minisiteri. Ibi birerekana ko imikorere ya gypsum mortar iterwa nubwoko bwihariye nubwiza bwa selulose ether yakoreshejwe.

Kimwe mu byiza byingenzi byo kwinjiza selile ya ether muri gypsum mortar ni uko itezimbere imikorere yuruvange. Gutunganya bivuga ubworoherane ibintu bishobora kuvangwa, gushyirwaho no guhuzwa. Gukora cyane gypsum minisiteri irashobora gukoreshwa hejuru yuburyo bworoshye, bikavamo kurangiza neza, byinshi. Ether ya selile irashobora kunoza imikorere yuruvange mukugabanya kwandura no kuva amaraso, bibaho mugihe ibice biremereye muri minisiteri bivuye mumivange mugihe cyo kubaka.

Usibye kugira ingaruka kumikorere, viscosity ya selulose ether izanagira ingaruka kumikorere ya gypsum mortar. Adhesion nubushobozi bwibikoresho guhuza nubundi buso. Kubaho kwa selulose ether muri gypsum mortar irashobora kunonosora imiterere yayo hejuru mukwongera aho uhurira no kugabanya umwuka wafashwe hagati yubutaka. Ether-viscosity selulose ethers ikora neza kuruta ether-viscosity ethers mugutezimbere gufatana kuko bitera umurunga ukomeye hagati yimiterere.

Undi mutungo wingenzi wa gypsum mortar nigihe cyo gushiraho, igihe bifata kugirango imvange ikomere kandi itezimbere imbaraga. Igenamiterere rya minisiteri ya gypsumu irashobora guhinduka wongeyeho selile ether, ishobora kugira ingaruka kumikorere ya gypsumu. Hydrasiyo ni reaction ya chimique ibaho mugihe amazi yongewe muri gypsumu, bikavamo gukora calcium sulfate dihydrate kristal.

Ubukonje bwa selile ether bugira ingaruka zikomeye kumikorere ya gypsum. Hejuru ya viscosity selulose ethers irashobora kunoza imikorere, imiterere yumuti hamwe nigihe cyo kuvanga, mugihe ethers yo hasi yubusa irashobora kugira ingaruka nke kuriyi miterere. Ingaruka yihariye ya selulose ether viscosity biterwa nibintu byinshi, harimo ubwoko nubunini bwa ether, ingano yingingo nogukwirakwiza gypsumu, nigipimo cyamazi na sima. Ubushakashatsi burakenewe kugira ngo dusobanukirwe neza isano iri hagati ya selile ya ether viscosity na gypsum mortar, ariko ibitabo bihari byerekana ko iki ari ikintu cyingenzi ugomba gusuzuma mugihe cyo gutegura ibikoresho byubaka.
