Hydroxypropyl methylcellulose (HPMC) ndi ether yosakhala ionic cellulose yopangidwa kuchokera ku cellulose yachilengedwe ya polima kudzera munjira zingapo zama mankhwala.Hydroxypropylmethylcellulose (HPMC) ndi ufa woyera wopanda fungo, wosakoma, wopanda poizoni womwe ukhoza kusungunuka m'madzi ozizira kuti ukhale wowonekera bwino wa viscous.Lili ndi katundu wa thickening, kumanga, kubalalika, emulsifying, filimu kupanga, suspending, adsorbing, gelling, pamwamba yogwira, kusunga chinyezi ndi kuteteza colloid.Mumatope, ntchito yofunikira ya hydroxypropyl methylcellulose ndikusunga madzi, komwe ndiko kuthekera kwa matope kusunga madzi.
1. Kufunika kosunga madzi mumatope
Mtondo wokhala ndi madzi ocheperako ndi wosavuta kukhetsa magazi ndikulekanitsa panthawi yoyendetsa ndi kusungirako, ndiko kuti, madzi amayandama pamwamba, mchenga ndi simenti pansi, ndipo uyenera kugwedezekanso musanagwiritse ntchito.Mtondo wokhala ndi kusungidwa bwino kwa madzi, popaka matope, malinga ngati matope osakaniza okonzeka akukhudzana ndi chipika kapena maziko, matope okonzeka okonzeka adzatengedwa ndi madzi, ndipo nthawi yomweyo, kunja kwa matope. matopewo amasungunula madzi m’mlengalenga, zimene zidzachititsa kuti madzi a mutondowo awonongeke.Madzi osakwanira adzakhudzanso hydration ya simenti ndipo imakhudza kukula kwabwino kwa mphamvu yamatope, zomwe zimapangitsa kuti pakhale mphamvu zochepa, makamaka mphamvu ya mawonekedwe pakati pa matope owuma ndi matope, zomwe zimapangitsa kuti pakhale kuphulika ndi kugwa kuchokera kumatope.
2. Njira yachikhalidwe yowongolera kasungidwe kamadzi mumatope
Njira yachikhalidwe ndiyo kuthirira maziko, koma sizingatheke kuonetsetsa kuti mazikowo ndi onyowa mofanana.Cholinga chabwino cha hydration cha matope a simenti pamunsi ndi: mankhwala a simenti amadzimadzi amalowa m'munsi pamodzi ndi njira yamadzi yoyamwa madzi, kupanga "kugwirizana kwakukulu" ndi maziko, kuti akwaniritse mphamvu yomangira yofunikira.Kuthirira molunjika pamwamba pa tsinde kungayambitse kubalalitsidwa kwakukulu mu kuyamwa kwamadzi m'munsi chifukwa cha kusiyana kwa kutentha, nthawi yothirira, komanso kufanana kwa madzi.Pansi pake imakhala ndi mayamwidwe ochepa amadzi ndipo idzapitirizabe kuyamwa madzi mumatope.Simenti ya simenti isanapitirire, madzi amatengedwa, zomwe zimakhudza kulowa kwa simenti hydration ndi hydration mankhwala mu masanjidwewo;tsinde lake lili ndi mayamwidwe aakulu amadzi, ndipo madzi a mumtondo amayenda pansi.Kuthamanga kwapakati kumayenda pang'onopang'ono, ndipo ngakhale wosanjikiza wochuluka wa madzi umapangidwa pakati pa matope ndi matrix, zomwe zimakhudzanso mphamvu ya mgwirizano.Choncho, kugwiritsa ntchito wamba m'munsi madzi njira osati kulephera mogwira kuthetsa vuto la mayamwidwe mkulu madzi pa khoma m'munsi, koma zidzakhudza kugwirizana mphamvu pakati matope ndi m'munsi, chifukwa hollowing ndi akulimbana.
3. Kusunga madzi moyenera
(1) Kuchita bwino kwambiri posungira madzi kumapangitsa kuti matope atseguke kwa nthawi yayitali, ndipo ali ndi ubwino womanga malo akuluakulu, moyo wautali wautumiki mu mbiya, ndi kusakaniza batch ndi kugwiritsa ntchito batch.
(2) Kuchita bwino kosunga madzi kumapangitsa simenti mumtondo kukhala ndi madzi okwanira, ndikuwongolera magwiridwe antchito amatope.
(3) Mtondo umakhala ndi ntchito yabwino yosungira madzi, zomwe zimapangitsa kuti matopewo asamapatulidwe komanso kukhetsa magazi, zomwe zimapangitsa kuti matopewo azigwira ntchito bwino komanso amamanga.
