- Ko nga hua Hydroxypropyl methyl cellulose mo te hanga e whakamahia nuitia ana hei whakapai ake i te mahi o nga taonga hangahanga hydrocoagulant, penei i te ciment me te gypsum.I roto i nga moata ciment-based, ka pai ake te pupuri i te wai, ka whakaroa i te wa whakatikatika me te wa whakatuwhera, me te whakaheke i te rere iri.
- 1. Te pupuri wai
- Te hanga motuhake hydroxypropyl methyl cellulose ki te karo i te kuhu o te wai ki roto i te pakitara.Ka noho te nui o te wai ki roto i te kumete, kia roa ake ai te wa whakamakuku o te sima.Ko te pupuri wai he rite ki te pokey o te wairewa eter cellulose i roto i te kumete.Ko te teitei ake o te pokey, ko te pai ake o te pupuri wai.Ka piki ake nga ngota ngota wai, ka heke te pupuri wai.Na te mea mo te nui o te hanga i whakatapua hydroxypropyl methyl cellulose solution, ko te pikinga o te wai te tikanga ka heke te pokey.Ma te pai ake o te pupuri wai ka roa ake te wa rongoa o te kumete kei te hanga.
- 2.whakapai ake te hanga
- Hydroxypropyl methyl cellulose HPMC tono ka taea te whakapai ake i te hanga moata.
- kaha 3.lubrication
- Ka mahi nga maakuta hau katoa hei makuku ma te whakaiti i te makuku o te mata me te awhina i te paura pai i roto i te kumete kia marara ina konatunatua ki te wai.
- 4. Iri parepare -
- Ko te pai o te kumete aatete ki te rere ko te tikanga karekau he kino o te rere iri, te rere whakararo ranei i te wa e mahi ana i nga papa matotoru.Ka taea te whakapai ake i te parenga rere ma te hanga i whakatapua hydroxypropyl methyl cellulose.Ina koa ko te whare hou i whakatapua ki te hydroxypropyl methyl cellulose ka taea e te moata te pai ake te iri atete rere.
- 5. Mirumiru ihirangi
- Ko te nui o te mirumiru o te mirumiru ka pai ake te tuku kumete me te kaha mahi, ka whakaiti i te hanga pakaru.Ka whakaitihia ano te uara kaha, te ahuatanga "liquefaction".Ko te ihirangi mirumiru te tikanga ka whakawhirinaki ki te wa whakakorikori.
