I-HPMC YB 515M

I-EipponCell HPMC YB 515M, eklanyelwe ngokukhethekile ukusetshenziswa kwe-adhesive okujwayelekile, inezinto ezilandelayo:

Umthelela ngesikhathi esivulekile sokunamathela kuthayela

Lapho i-latex powder ne-cellulose ether HPMC zikhona odakeni olumanzi, i-RDP powder ibonisa amandla aqinile okubopha ngomkhiqizo we-cement hydration, kuyilapho i-cellulose ether ithinta ngokuyinhloko uketshezi lwe-interstitial, ithinta i-viscosity nesikhathi esimisiwe sodaka.

I-RDP powder ibonisa okunamathiselwe okuthuthukisiwe emikhiqizweni ye-cement hydration, kuyilapho i-cellulose ether ithinta ngokuyinhloko uketshezi lwe-interstitial, okuthinta i-viscosity yodaka kanye nesikhathi esimisiwe.

Ukuhlalisana kwe-latex powder kanye ne-cellulosic ether HPMC odakeni olumanzi kuthinta izakhiwo zodaka, ne-RDP powder enamandla amakhulu okubopha kanye ne-cellulosic ether ethinta i-viscosity nokubeka isikhathi ngokuba khona kwayo emanzini aphakathi.

Ithonya emandleni okudonsa okunamathiselwe kuthayela

I-cellulose ether odakeni aluhlinzeki nje ngezinto ezizuzisayo, kodwa futhi ibambezela amandla okushintshana kwe-hydration kasimende ngokukhangiswa kumkhiqizo onamanzi esikhundleni sesigaba sokuqala samaminerali.Lo mphumela wokuvinjelwa ubangelwa ukuhamba okuncishisiwe kwama-ion kusixazululo se-pore ngenxa yokwanda kwe-viscosity okubangelwa i-cellulose ether.

Ukuba khona kwe-cellulose ether ezinhlelweni zikasimende kuvimbela i-hydration kinetics ngokukhangisa umkhiqizo onamanzi esikhundleni sesigaba sokuqala samaminerali, kuyilapho kukhulisa i-viscosity yesisombululo se-pore, ngaleyo ndlela kunciphisa ukuhamba kwe-ion futhi kuqhubekisele phambili ijubane lenqubo yokukhipha amanzi.

Umphumela wokuvinjelwa kwe-cellulose ether ku-hydration usimende ufinyelelwa ngokuyinhloko ngokukhangisa kwawo kumkhiqizo onamanzi kanye nokwanda okulandelanayo kwe-viscosity yesixazululo se-pore, okuvimbela ukuhamba kwe-ion futhi kubambezeleke ukuguquguquka kwe-hydration jikelele.
