Hydroxypropyl methyl selulose irashobora kunoza ikwirakwizwa rya sima ya sima

Kurwanya gutatanya ni indangagaciro ya tekinike yo gupima ubuziranenge bwa anti-dispersant.Hydroxypropyl methyl selulose ni ifumbire mvaruganda ya polymer, izwi kandi nka resin-soluble resin cyangwa polymer-soluble polymer.Yongera ubudahangarwa bwuruvange mukongera ubwiza bwamazi avanze.Nubwoko bwibikoresho bya hydrophilique polymer, bishobora gushonga mumazi bigakora igisubizo cyangwa amazi yatatanye.Ubushakashatsi bwerekana ko iyo ubwinshi bwa sisitemu ya naphthalene superplasticizer yiyongereye, kongeramo superplasticizer bizagabanya kurwanya ikwirakwizwa rya minisiteri nshya.Ibi biterwa nuko serivise ya naphthalene ikora neza cyane igabanya amazi ni iyimikorere ikora hejuru, mugihe igikoresho cyo kugabanya amazi cyongewe kuri minisiteri, igabanya amazi mugice cya sima hejuru yubutaka bwa sima hamwe nubushakashatsi bumwe, flokculasiyo yanga amashanyarazi imiterere yibice bya sima byakozwe mukugabana, kuzinga muburyo bwo kurekura amazi, bizatera igihombo cyigice cya sima.Muri icyo gihe, usanga ko hamwe no kwiyongera kwa HPMC, kurwanya ikwirakwizwa rya sima nshya ya sima nibyiza kandi byiza.

Imbaraga ziranga ibintu bifatika:

HPMC mumazi yo mumazi adakwirakwiza beto yashyizwe mubikorwa byubwubatsi bwikiraro cya gari ya moshi, kandi igipimo cyimbaraga cyari C25.Nyuma yikizamini cyibanze, dosiye ya sima ni 400kg, ifumbire ivanze na silika fume 25kg / m3, dosiye nziza ya HPMC ni 0,6% ya sima ya sima, igipimo cya sima cyamazi ni 0.42, igipimo cyumucanga ni 40%, naphthalene ikora neza amazi agabanya umusaruro ni 8% ya dosiye ya sima, urugero rwa beto mukirere 28d, imbaraga zisanzwe ni 42.6MPa, Impuzandengo yimbaraga zamazi yo mumazi yasutse beto ifite uburebure bwa 60mm mumazi ni 36.4mpa muminsi 28, naho igipimo cyimbaraga za beto zakozwe muri amazi na beto ikozwe mu kirere ni 84.8%, byerekana ingaruka zikomeye.

1. Kwiyongera kwa HPMC bifite ingaruka zigaragara zo kudindiza imvange ya minisiteri.Hamwe no kwiyongera kwa dosiye ya HPMC, igihe cyo gushiraho minisiteri kiraramba gikurikiranye.Muburyo bumwe bwa dosiye ya HPMC, igihe cyo gushiraho minisiteri yo mumazi ni kirekire kuruta icy'umwuka.Iyi mikorere ni ingirakamaro mu kuvoma beto yo mumazi.

2, ivanze na hydroxypropyl methyl selulose ya sima ya sima nshya ifite ubumwe bwiza, hafi nta kintu cyo kuva amaraso.

3, dosiye ya HPMC namazi ya minisiteri yabanje kugabanuka hanyuma yiyongera cyane.

4. Kwinjiza kugabanya amazi bigabanya ikibazo cyo kongera amazi ya minisiteri, ariko bigomba kugenzurwa muburyo bukwiye, bitabaye ibyo rimwe na rimwe bizagabanya kurwanya ikwirakwizwa ry’amazi ya sima nshya.

5. Hariho itandukaniro rito mumiterere hagati ya HPMC ivanze ya sima net ya slurry hamwe nubusa, kandi hariho itandukaniro rito mumiterere no guhuza hagati y'amazi yasutswe na sima hamwe nikirere cyasutswe na sima net.Ikigereranyo cya 28d cyamazi yo mumazi arekuye gato.Impamvu nyamukuru nuko iyongerwaho rya HPMC rigabanya cyane igihombo no gutatanya sima mugihe cyo gusuka amazi, ariko kandi bikagabanya urwego rwo guhuza sima.Mu mushinga, muburyo bwo kwemeza ko amazi yo mu mazi adakwirakwira, kuvanga HPMC bigabanuka uko bishoboka kose.

6, ongeramo HPMC mumazi ntabwo akwirakwiza ibintu bifatika, kugenzura ingano yimbaraga nziza, umushinga wikigereranyo werekana ko igipimo cyimbaraga zo gukora beto mumazi no gukora mukirere ari 84.8%, ingaruka ni nyinshi.
