Kurwanya-gutatanya nigipimo cyingenzi cya tekiniki yo gupima ubuziranenge bwibikorwa byo kurwanya.Hydroxypropyl methylcellulose ni ifumbire mvaruganda ya polymer, izwi kandi nka resin-soluble resin cyangwa polymer-soluble polymer.Yongera ubudahangarwa bwuruvange mukongera ubwiza bwamazi avanze.Nibikoresho bya hydrophilique polymer.Irashobora gushonga mumazi kugirango ikemuke cyangwa itatanye.Ubushakashatsi bwerekana ko iyo ubwinshi bwa naphthalene bushingiye ku buhanga buhanitse bwa superplasticizer bwiyongereye, hiyongereyeho superplasticizer bizagabanya kurwanya ikwirakwizwa rya sima ivanze.Ni ukubera ko naphthalene ishingiye ku kugabanya amazi meza cyane igabanya amazi.Iyo kugabanya amazi byongewe kuri minisiteri, kugabanya amazi bizaba byerekejwe hejuru yubutaka bwa sima kugirango ubuso bwa sima bugire umushahara umwe.Uku kwanga amashanyarazi gutuma uduce twa sima dukora Imiterere ya flocculation ya sima irasenywa, hanyuma amazi apfunyitse muri iyo miterere ararekurwa, bizatera igihombo cya sima.Muri icyo gihe, usanga hamwe no kwiyongera kwa HPMC, kurwanya ikwirakwizwa rya sima ya sima nshya bigenda byiyongera kandi byiza.
01. Kwiyongera kwa HPMC bifite ingaruka zigaragara zo kudindiza imvange ya minisiteri.Hamwe no kwiyongera kwa HPMC, igihe cyo gushiraho minisiteri cyongerewe uko bikurikirana.Mubintu bimwe bya HPMC, minisiteri ikozwe mumazi irihuta kuruta iyo mu kirere Molding ifata igihe kirekire kugirango ishyire.Iyi mikorere ni ingirakamaro mu kuvoma beto yo mumazi.

0.Icyitegererezo cyakozwe munsi yamazi muminsi 28 ni gito.Impamvu nyamukuru nuko iyongerwaho rya HPMC rigabanya cyane gutakaza no gutatanya sima mugihe usutse mumazi, ariko kandi bikagabanya ubwuzuzanye bwamabuye ya sima.Mu mushinga, hashingiwe ku kwemeza ingaruka zo kudatatanya munsi y’amazi, urugero rwa HPMC rugomba kugabanuka uko bishoboka kose
HPMC mumazi yo mumazi adashobora gukwirakwira ya beto ikoreshwa mugukora ikiraro cya fondasiyo ya gari ya moshi, kandi urwego rwo gushushanya ni C25.Ukurikije ikizamini cyibanze, ingano ya sima ni 400 kg, umwotsi wa silika wuzuye ni 25kg / m3, urugero rwiza rwa HPMC ni 0,6% byamafaranga ya sima, igipimo cyamazi-sima ni 0.42, umusenyi ni 40%, n'umusaruro wa naphthalene ushingiye ku kugabanya amazi meza cyane ni ingano ya sima ni 8%, urugero rwa beto mu kirere iminsi 28, imbaraga zisanzwe ni 42.6MPa, beto yo mumazi ifite uburebure bwa 60mm muminsi 28 , impuzandengo yimbaraga ni 36.4MPa, igipimo cyingufu za beto yakozwe namazi na beto ikozwe mwumwuka 84.8%, ingaruka ni nyinshi.
