Hydroxypropyl Methyl Cellulose Mtengo wa HPMC
1. Ili ndi kukhazikika kwa asidi ndi alkali, ndipo njira yake yamadzimadzi imakhala yokhazikika pa pH = 2 ~ 12. Koloko ndi madzi a mandimu sakhala ndi zotsatira zambiri pa ntchito yake, koma zamchere zimatha kufulumizitsa kusungunuka kwake ndikuwongolera pang'ono kukhuthala.
2. Mtengo wa HPMCndi yothandiza posungira madzidothi loumadongosolo, amene angathe kuchepetsa mlingo wa matope katulutsidwe ndi stratification, kusintha cohesiveness matope, bwino ziletsa mapangidwe matope ming'alu pulasitiki, ndi kuchepetsa mtondo pulasitiki akulimbana index.
3, ndi electrolyte yopanda ionic komanso yopanda polymeric, yomwe imakhala yosasunthika muzitsulo zamadzimadzi zamchere zamchere ndi ma electrolyte a organic, ndipo imatha kuwonjezeredwa ku zipangizo zomangira kwa nthawi yaitali kuti zitsimikizidwe kuti kulimba kwake kumakhala bwino.
4, ntchito yogwiritsira ntchito matope yakhala bwino kwambiri, matope akuwoneka kuti ali ndi "mafuta", amatha kupangitsa kuti khomalo likhale lodzaza, losalala pamwamba, kotero kuti matope ndi maziko olimba kwambiri, ndipo amatha kuwonjezera nthawi yogwira ntchito.
Kusunga madzi
Kuzindikira kwa machiritso amkati kumathandizira kuwongolera kwamphamvu kwanthawi yayitali, kuletsa kutuluka kwa magazi, kupewa kukhazikika kwa matope, kufota komanso kuwongolera kukana kusweka kwamatope.
Kukhuthala
Pewani kusankhana, sinthani matope kuti mufanane, onjezerani mphamvu zomangira zonyowa, ndikuwongolera magwiridwe antchito oletsa kupachika.
Kuwongolera mpweya
Kupititsa patsogolo ntchito yamatope. Kuchuluka kwa kukhuthala kwa cellulose, kutalikirapo kwa unyolo wa maselo, m'pamenenso mpweya umalowa m'thupi.
Kuchedwa coagulation
Gwirizanani ndi kusunga madzi kuti muwonjezere nthawi yotsegulira matope
Hydroxypropyl Wowuma ether
1. Kuchuluka kwa hydroxypropyl mu wowuma ether kumapereka dongosolo lokhazikika la hydrophilicity, kutembenuza madzi aulere kukhala madzi omangika, omwe amagwira ntchito yabwino yosungira madzi.
2. Ma etha owuma okhala ndi ma hydroxypropyl osiyanasiyana ali ndi kuthekera kosiyanasiyana kothandizira mapadi posunga madzi pa mlingo womwewo.
3. The m'malo hydroxypropyl gulu kumawonjezera kutupa digirii m'madzi ndi compresses danga tinthu otaya, motero kukwaniritsa zotsatira za thickening ndi mamasukidwe akayendedwe kuwonjezeka.
mafutatropic mafuta
Wowuma ether amamwazikana mwachangu mu matope, kusintha rheology ya matope ndikuupereka thixotropy. Pamene mphamvu yakunja ikugwiritsidwa ntchito, kukhuthala kwa matope kudzachepetsedwa, kuonetsetsa kuti kumanga bwino ndi kupopera, ndikupereka thixotropy. Zimamveka bwino. Mphamvu yakunja ikachotsedwa, kukhuthala kumawonjezeka, zomwe zimapatsa matope kuti asagwedezeke. Pakati pa ma putty powders, ili ndi ubwino wowongolera kuwala kwa mafuta a putty ndi kuwala kowala.
Wothandizira madzi posungira zotsatira
Wowuma ether palokha ali ndi hydrophilic katundu chifukwa cha udindo wa hydroxypropyl magulu mu dongosolo. Zikaphatikizidwa ndi cellulose kapena kuwonjezeredwa mumtengo wina ku matope, zimatha kuwonjezera kusungirako madzi mpaka pamlingo wina ndikuwongolera nthawi yowuma pamwamba.
Anti-sag ndi anti-slip
Zabwino kwambiri zotsutsana ndi sag komanso mawonekedwe ake.
Redispersible polima ufa
1. Sinthani magwiridwe antchito a matope.Redispersible ufar or RDPparticles amamwazikana mu dongosolo, kupereka dongosolo bwino fluidity ndi kuwongolera workability ndi workability wa matope.
2. Limbikitsani mphamvu yomangira matope. Pambuyo pa ufa wa rabara utamwazikana mufilimu, zinthu zopanda organic ndi organic mumtondo zimatha kusakanikirana. Zingaganizidwe kuti simenti ndi mchenga mumatope ndi mafupa, ndipo ufa wa latex umapanga mitsempha. Kugwirizana kumawonjezeka, mphamvu imawonjezeka, ndipo mawonekedwe osinthika amapangidwa pang'onopang'ono.
3. Limbikitsani kupirira kwanyengo kwa matope. Freeze-thaw resistant latex powder ndi utomoni wa thermoplastic wokhala ndi kusinthasintha kwabwino, zomwe zingapangitse matope kuyankha kusintha kwa kunja kwa kuzizira ndi kutentha, kuteteza bwino kuti matope asagwedezeke chifukwa cha kusintha kwa kutentha.
4. Kupititsa patsogolo mphamvu ya matope. Polima ndi simenti slurry zimapanga zabwino zowonjezera. Pamene ming'alu imayambitsidwa ndi mphamvu zakunja, polima imatha kutambasula ming'alu ndikulepheretsa kukula kwa ming'alu, potero kumapangitsa kuti ming'aluyo ikhale yolimba komanso kupunduka kwa matope.
