Hydroxypropyl Methylcellulose (HPMC)ndizofunikira zomangira zowonjezera, zomwe zimagwiritsidwa ntchito kwambiri mumatope a simenti, matope owuma, zokutira ndi minda ina. HPMC imagwira ntchito yofunika kwambiri posungira madzi mumatope, ndipo imatha kusintha kwambiri kugwirira ntchito, kusungunuka, kumamatira komanso kukana kwamatope. Makamaka pomanga amakono, imagwira ntchito yosasinthika pakuwongolera bwino komanso kupanga matope.
1. Makhalidwe oyambira a HPMC
HPMC ndi chotumphukira cha cellulose chosinthidwa ndi chemistry ya cellulose, yokhala ndi kusungunuka kwamadzi bwino, kumamatira komanso kukhuthala. Mamolekyu a AnxinCel®HPMC ali ndi magulu awiri, hydroxypropyl ndi methyl, zomwe zimapangitsa kuti zikhale ndi makhalidwe ophatikizira hydrophilicity ndi hydrophobicity, ndipo amatha kugwira bwino ntchito yake pansi pa zochitika zosiyanasiyana zachilengedwe. Ntchito zake zazikulu ndi monga thickening, kusunga madzi, kukonza rheology ndi kumamatira matope, etc.
2. Tanthauzo ndi kufunika kosunga madzi
Kusungidwa kwamadzi mumatope kumatanthauza kuthekera kwa matope kusunga madzi panthawi yomanga. Kutayika kwa madzi mumatope kumakhudza mwachindunji njira yake yowumitsa, mphamvu ndi ntchito yomaliza. Madzi akakhala nthunzi msangamsanga, simenti ndi zinthu zina za simenti zomwe zili mumtondo sizikhala ndi nthawi yokwanira yochitira hydration, zomwe zimapangitsa kuti matope azikhala osakwanira komanso osamamatira bwino. Choncho, kusunga madzi bwino ndiye chinsinsi chowonetsetsa kuti matope ali abwino.
3. Zotsatira za HPMC pakusunga madzi mumatope
Kuphatikizika kwa HPMC mumtondo kumatha kusintha kwambiri kusungidwa kwamadzi mumatope, komwe kumawonetseredwa m'mbali zotsatirazi:
(1) Kupititsa patsogolo mphamvu yosungira madzi mumatope
HPMC imatha kupanga mawonekedwe ngati hydrogel mumatope, omwe amatha kuyamwa ndikusunga madzi ambiri, potero amachedwetsa kutuluka kwa madzi. Makamaka pomanga kutentha kwambiri kapena malo owuma, kusunga madzi kwa HPMC kumagwira ntchito yofunika kwambiri. Pokonza kusungirako madzi, HPMC ikhoza kuonetsetsa kuti madzi mumatope amatha kutenga nawo mbali pakuchitapo kanthu kwa simenti ndikuwongolera mphamvu ya matope.
(2) Kupititsa patsogolo kutulutsa madzi ndi kugwira ntchito kwamatope
Panthawi yomanga, matope amafunika kusunga madzi enaake kuti athandize ogwira ntchito yomanga. Kusungidwa bwino kwa madzi kumatha kuchepetsa liwiro lowumitsa matope, kupangitsa kuti ikhale yocheperako komanso yosavuta kwa ogwira ntchito yomanga kuti agwire ntchito monga kupaka ndi kupala. Komanso, HPMC akhoza kusintha mamasukidwe akayendedwe matope ndi kupewa matope kulekana kapena sedimentation, potero kukhalabe chimodzimodzi.
(3) Kupewa kung'ambika pamwamba pamatope
Pambuyo HPMC kusintha madzi kusunga matope, akhoza kuchepetsa evaporation mofulumira madzi pa matope pamwamba ndi kuchepetsa chiwopsezo chosweka. Makamaka m'malo okhala ndi kutentha kwambiri kapena chinyezi chochepa, kutuluka kwamadzi mwachangu kumatha kuyambitsa ming'alu pamtunda wamatope. HPMC imathandiza kulamulira chinyezi bwino matope ndi kuchepetsa kutayika kwa madzi, kusunga umphumphu wa matope ndi kupewa mapangidwe ming'alu.
(4) Kutalikitsa nthawi yotsegula yamatope
Nthawi yotseguka ya matope imatanthawuza nthawi yomwe matope amatha kugwiritsidwa ntchito panthawi yomanga. Nthawi yochepa kwambiri yotseguka idzakhudza ntchito yomanga. Kuwonjezera kwa HPMC kumatha kutalikitsa nthawi yotseguka yamatope, kupatsa ogwira ntchito yomanga nthawi yochulukirapo kuti agwire ntchito monga kukwapula ndi kupaka. Makamaka muzomangamanga zovuta, kutalikitsa nthawi yotseguka kumatha kuonetsetsa kuti matope amamatira ndikugwira ntchito.
4. Njira ya mphamvu ya HPMC pa kusunga madzi mumatope
Njira zazikuluzikulu za HPMC pakuwongolera kusunga madzi mumatope ndi izi:
(1) Kuchuluka kwa madzi ndi kapangidwe ka maselo
Mamolekyu a HPMC ali ndi magulu ambiri a hydrophilic hydroxyl (-OH) ndi hydroxypropyl (-CH2OH), omwe amatha kupanga zomangira za haidrojeni ndi mamolekyu amadzi ndikuwonjezera kutengeka kwa mamolekyu amadzi. Kuphatikiza apo, HPMC ili ndi mamolekyu akulu akulu ndipo imatha kupanga maukonde amitundu itatu mumtondo, yomwe imatha kugwira ndikusunga madzi ndikuchepetsa kuchuluka kwa madzi.
(2) Wonjezerani kusasinthasintha ndi kukhuthala kwa matope
Pamene AnxinCel®HPMC ikuwonjezeredwa ku matope ngati thickener, idzawonjezera kwambiri kusasinthasintha ndi kukhuthala kwa matope, kupanga matope kukhala okhazikika komanso kuchepetsa kutaya madzi. Makamaka m'malo omangira owuma, kukhuthala kwa HPMC kumathandizira kukonza magwiridwe antchito odana ndi matope.
(3) Kupititsa patsogolo kukhazikika kwadongosolo lamatope
HPMC ikhoza kupititsa patsogolo mgwirizano wa matope ndikuwongolera kukhazikika kwa matope kudzera muzochita zake zapakati. Kukhazikika kumeneku kumapangitsa kuti chinyontho cha matope chikhalebe pakati pa tinthu tating'ono ta simenti kwa nthawi yayitali, potero kuonetsetsa kuti simenti ndi madzi zimachita bwino komanso kukulitsa mphamvu ya matope.
5. Zotsatira za HPMC pakugwiritsa ntchito
M'magwiritsidwe ntchito,Mtengo wa HPMCnthawi zambiri amagwiritsidwa ntchito pamodzi ndi zowonjezera zina (monga mapulasitiki, osakaniza, ndi zina zotero) kuti akwaniritse ntchito yabwino yamatope. Kupyolera muyeso wololera, HPMC imatha kugwira ntchito zosiyanasiyana mumitundu yosiyanasiyana yamatope. Mwachitsanzo, mumatope wamba simenti, matope a simenti, matope owuma, etc., amatha kusintha bwino kusungirako madzi ndi zinthu zina zamatope.
Udindo wa HPMC mumatope sungathe kuchepetsedwa. Imawongolera kwambiri ubwino ndi kugwiritsa ntchito matope mwa kukonza kusungirako madzi mumatope, kuwonjezera nthawi yotseguka, ndi kupititsa patsogolo ntchito yomanga. Pakumanga kwamakono, ndi kuchulukirachulukira kwaukadaulo wa zomangamanga komanso kuwongolera kosalekeza kwa ntchito zamatope, HPMC, monga chowonjezera chachikulu, ikugwira ntchito yofunika kwambiri.
