Ether Cellulose ki te moata gypsum

Ka taea te whakamahi i te carboxymethyl cellulose me te methyl cellulose hei taonga pupuri wai mo te raima, engari he iti ake te kaha o te pupuri wai o te carboxymethyl cellulose i tera o te methyl cellulose, me te carboxymethyl cellulose kei roto te tote konutai, no reira kaore e pai mo te raima. pari. He whakaroa, he whakaheke i te kaha o te raima o paris. Ko te Methyl cellulose he whakaurunga pai mo nga taonga cimentitious gypsum e whakauru ana i te pupuri wai, te whakakaha, te whakakaha, me te viscosifying, engari ko etahi momo ka pa te whakaroa ina he nui te inenga. teitei ake i te carboxymethyl cellulose. Mo konei, ko te nuinga o nga rawa whakahiato gypsum gelling e mau ana i te tikanga mo te whakakotahi i te carboxymethyl cellulose me te methyl cellulose, ehara i te mea ko o raatau ahuatanga anake (penei i te aukati o te carboxymethyl cellulose, te whakakaha o te methyl cellulose), me te whakamahi i o raatau painga noa. (pērā i te pupuri wai me te pānga mātotoru). Ma tenei huarahi, ka taea te whakapai ake i nga mahi pupuri wai o nga mea raima gypsum me te mahi matawhānui o nga mea raima gypsum, i te mea ka mau te pikinga utu ki te waahi iti rawa.

He aha te hiranga o te pokey o te methyl cellulose ether mo te moata gypsum?

Viscosity Ko te tawhā nui omethyl cellulose ethermahi.

Ko te tikanga, ko te teitei ake o te pokey, ko te pai ake o te pupuri wai o te moata gypsum. Heoi, ko te teitei ake o te pokey, ko te teitei ake o te taumaha ngota o te methyl cellulose ether, me te heke o tona whakarewatanga ka pa kino ki te kaha me te mahi hanga o te moata. Ko te teitei ake o te pokey, ka tino kitea te kaha o te whakapawera ki runga i te kumete, engari kaore i te rite tonu. Ko te teitei ake o te pokey, ka kaha ake te poiri o te kumete maku. I te wa o te hanga, ka kitea he piri ki te kirikiri me te piri nui ki te tïpako. Engari ehara i te mea pai ki te whakanui ake i te kaha o te hanganga o te kumete maku ano. I tua atu, i te wa e hanga ana, kaore e kitea te mahi anti-sag o te kumete maku. Engari, he pai rawa te mahi o etahi momo pokey reo me te iti engari kua whakarereketia te methyl cellulose ethers hei whakapai ake i te kaha o te hanganga o te kumete maku.

He aha te nui o te pai o te cellulose ether ki te kumete?

Ko te pai he tohu mahi nui o te methyl cellulose ether. Ko te MC e whakamahia ana mo te paura paura maroke e hiahiatia ana he paura me te iti o te wai, me te pai hoki me 20% ki te 60% o te rahi o te matūriki kia iti iho i te 63m. Ka pa te pai ki te whakarewatanga o te methyl cellulose ether. Ko te MC nui te nuinga o te kirikiri, he ngawari ki te marara me te memeha i roto i te wai kaore he agglomeration, engari he tino puhoi te tere o te whakakorenga, na reira kaore e pai mo te whakamahi i te paura paura maroke. Ko etahi o nga hua o te kainga he kopa, ehara i te mea ngawari ki te marara me te memeha ki te wai, he ngawari ki te whakahiato. I roto i te moata paura maroke, ka marara te MC i waenga i nga whakahiato, nga whakakii pai me te raima me etahi atu rauemi cimenting. Ko te paura pai anake ka taea te karo i te methyl cellulose ether agglomeration ina ranu ki te wai. Ina tapirihia te MC ki te wai hei whakakore i nga agglomerates, he tino uaua ki te marara me te memeha. Ko te Coarse MC ehara i te mea moumou noa, engari ka whakaheke i te kaha o te rohe o te kumete. Ina utaina he moata paura maroke ki tetahi waahi nui, ka tino heke te tere whakaora o te moata o te rohe, ka puta nga kapiti na te rereke o nga wa whakaora. Mo te kumete rehu me te hanga miihini, he teitei ake te whakaritenga mo te pai na te poto ake o te wa whakaranu.

Ko te pai o te MC he paanga ano ki tana pupuri wai. Ko te tikanga, mo te methyl cellulose ethers he rite tonu te potata engari he rereke te pai, i raro i te nui o te taapiri, ko te pai ake ka pai ake te painga o te pupuri wai.
