Mphamvu ya hydroxypropyl starch ether pamitengo yamatope
Hydroxypropyl starch ether (HPS), wowuma wofunikira wosinthidwa ndi mankhwala, amagwira ntchito yofunika kwambiri pakugwiritsa ntchito zida zomangira, makamaka matope, chifukwa chamankhwala ake apadera. Kuyambitsidwa kwa HPS kumapangitsa kuti matope azigwira bwino ntchito makamaka pokhudza mawonekedwe a rheological, kusunga madzi, kulimba kwa ma bond komanso kukana kwamatope.
1. Kusintha rheological katundu
Kupititsa patsogolo ntchito yomanga: HPS imatha kusintha kwambiri magwiridwe antchito amatope. Popeza molekyu ya HPS ili ndi mphamvu yamphamvu ya hydration komanso kusinthika kwamakasitomala, imatha kupanga matope kukhala osasinthasintha koyenera panthawi yosakanikirana. Izi zimapangitsa kuti dothi likhale losavuta kufalikira komanso losalala, potero zimakulitsa luso la zomangamanga.
Kusintha mamasukidwe akayendedwe: HPS imatha kusintha mawonekedwe a matope, kuwapangitsa kuwonetsa mikhalidwe yometa ubweya. Katunduyu amapangitsa kuti matope azikhala amadzimadzi kwambiri akamameta ubweya (monga nthawi yosakaniza kapena yomanga), ndikusunga mamasukidwe enaake pamalo osasunthika kuti apewe kugwedezeka ndi tsankho.
2. Konzani kasungidwe ka madzi
Imachedwetsa kutuluka kwa madzi: HPS imatha kusunga madzi bwino popanga netiweki mkati mwa matope. Mkhalidwewu ndi wofunikira kwambiri pakuchita kwa matope, makamaka m'malo otentha kapena owuma. Kuchedwetsa kutuluka kwa madzi kumatha kupititsa patsogolo mphamvu zoyamba komanso zomangira zamatope.
Limbikitsani njira yowumitsa matope: Kusungidwa bwino kwa madzi kungapangitse kuti matopewo akhale olimba, kuchepetsa ming'alu ya matope chifukwa cha kutaya madzi ambiri, ndikuwonjezera kukana kwa ming'alu ya chinthu chomwe chamalizidwa.
3. Limbikitsani kugwirizana
Limbikitsani kumamatira pakati pa matope ndi gawo lapansi: HPS imatha kupanga zomatira zolimba zakuthupi ndi zamankhwala pakati pa matope ndi gawo lapansi (monga khoma kapena pansi). Izi makamaka zimatheka chifukwa chakuti HPS, yomwe ili ndi hydrated, imatha kudzaza pores mu microstructure ya matope ndikuwonjezera malo olumikizana, motero kumapangitsanso mphamvu zomangira.
Limbikitsani kukana kukameta ubweya: Kuyambitsa kwa HPS kumatha kupanga matope kukhala olimba kwambiri atachiritsa ndikukulitsa kukana kwake. Izi ndizofunikira makamaka pazigawo zamapangidwe zomwe zimakhudzidwa ndi kupsinjika kwamakina, monga kukonza kapena kulimbikitsa ntchito, pomwe mphamvu yomangirira yamatope ndi yofunika kwambiri pakuwonetsetsa chitetezo chadongosolo.
4. Sinthani kukana kwa ming'alu
Chepetsani ming'alu ya shrinkage: HPS imachepetsa chiopsezo cha ming'alu ya shrinkage mwa kukonza kasungidwe ka madzi mumtondo ndi kuchepetsa kutsika komwe kumachitika chifukwa cha kutuluka kwa madzi. Kuphatikiza apo, mawonekedwe a netiweki opangidwa ndi HPS mumtondo amathandizanso kuyamwa ndi kufalitsa kupsinjika, kumachepetsanso kuchitika kwa ming'alu.
Limbikitsani kulimba kwa matope: Kukhalapo kwa HPS kumapangitsa kuti matopewo athe kusinthika bwino ndipo amatha kuthana bwino ndi kusintha kwa kutentha kozungulira komanso kupindika pang'ono kwa zinthu zoyambira. Kulimba kumeneku kumapangitsa kuti matope asamaphwanyike kwambiri akagwidwa ndi mphamvu zakunja, motero amapangitsa kuti matopewo azikhala olimba.
5. Zowonjezera zina
Limbikitsani kukana kuzizira: HPS imathandizira kachulukidwe ndi kufanana kwa matope ndikuchepetsa porosity mkati mwa matope, zomwe zimakhala ndi zotsatira zabwino pakukulitsa kukana kwa matope. Katunduyu ndi wofunikira makamaka m'malo otentha kwambiri ndipo amathandiza kukulitsa moyo wautumiki wamatope m'malo ozizira.
Kusunthika kukana kuvala: Chifukwa cha kuwongolera kwapang'onopang'ono kwa HPS, kulimba kwa pamwamba ndi kachulukidwe ka matope kumawongoleredwa, ndikupangitsa kuti iwonetse kukana kuvala bwino. Izi ndizofunikira makamaka kwa ma screeds apansi omwe amatha kukangana pafupipafupi komanso kuvala.
Kugwiritsa ntchito hydroxypropyl wowuma ether mu matope kwambiri bwino rheological katundu, kusunga madzi, mphamvu chomangira ndi kukana ming'alu, potero kumapangitsanso ntchito yomanga ndi kulimba kwa matope. Pakumanga kwamakono, kugwiritsa ntchito HPS kwakhala njira imodzi yofunika kwambiri yolimbikitsira ntchito yamatope, yomwe ili yofunika kwambiri pakuwongolera zonse komanso moyo wa zida zomangira.
