Te awenga o te cellulose ether ki runga i te kumete whakamaarama whaiaro

Ko nga moata whakataurite-whaiaro e whakawhirinaki ana ki o raatau ake taumaha ki te hanga i tetahi turanga papatahi, maeneene me te pakari i runga i te tïpako, ka taea e etahi atu rawa te whakatakoto, te herea ranei, me te whakatutuki i nga waahanga nui, pai mo te hanga.Na reira, ko te tino rere o te wai he mea tino nui o te moata whakamaarama whaiaro.Me whai tohu ano mo te pupuri wai me te kaha honohono, kaore he percolation me te wehewehe, he adiabatic me te iti te pāmahana.

Me pai te wai o te kumete whakamaarama whaiaro, engari ko te nuinga o te 10-12cm noa te rere o te slurry sima;Ko te cellulose ether te whakauru matua moata kua oti te whakauru, ahakoa he iti rawa te moni taapiri, ka taea e ia te whakapai ake i te mahi moata, ka taea te whakapai ake i te riterite moata, te mahi, te mahi honohono me te mahi pupuri wai.He mahi tino nui i roto i te mara o te kumete kua rite.

1 Hurirangi

He nui te awenga o te ether cellulose ki te pupuri wai, te rite me te mahi o te kumete.Otirā hei moata whakaōrite-whaiaro, ko te wīwī tētahi o ngā tino tohu hei arotake i te mahi whakaōrite-whaiaro.Ka taea te whakatika i te rere o te kumete ma te huri i te nui o te cellulose ether i raro i te kaupapa o te whakarite i te hanganga noa o te kumete.Ko te nui o te ihirangi ka whakaiti i te rere o te kumete, no reira, me whakahaere te nui o te cellulose ether i roto i te awhe whaitake.

2 Te pupuri wai

Ko te moata pupuri wai he tohu nui mo te pumau o nga waahanga o roto o te moata ciment.Kia pai ai te tauhohenga o te reera, ka taea te whakamahi i te nui o te cellulose ether mo te wa roa hei pupuri i te wai ki roto i te kumete.Ko te tikanga, ka piki ake te nui o te cellulose ether, ka piki hoki te pupuri wai o te kumete.I tua atu, he nui te awe o te viscosity o te cellulose ether ki te pupuri wai o te kumete;te teitei te pokey, te pai te pupuri wai.

3 Te wa whakarite

Ko te etera cellulose he aukati i te kumete.Na te pikinga o te ihirangi cellulose ether, ka roa te wa whakatakoto mo te kumete.A, he nui te ihirangi o te cellulose ether, ka tino kitea te hua o te hydration hydration tuatahi o te ciment.

4 Te kaha flexible me te kaha compressive

I te nuinga o te korero, ko te kaha tetahi o nga paearu arotakenga nui o te ranunga whakamaora o nga rawa cimentitious.Ka whakahekehia te kaha o te pupuhi me te kaha o te kumete i te wa e piki ake ai te ihirangi o te cellulose ether.
