Kodi kuwonjezeredwa kwa HPMC kumakhudza bwanji kulimba kwa matope?

Limbikitsani kasungidwe ka madzi: HPMC imatha kusintha kwambiri kusungidwa kwamadzi mumatope. Mlingo wochepa wa HPMC ukhoza kusintha kwambiri kusunga kwamadzi mumatope. Mwachitsanzo, pamene mlingo ndi 0.02%, kuchuluka kwa madzi osungira madzi kumawonjezeka kuchokera ku 83% mpaka 88%; pamene mlingo ndi 0.2%, madzi osungira madzi amafika 97%. Kuchita bwino posungira madzi kumapangitsa kuti simenti ikhale yokwanira komanso imalimbitsa mphamvu ndi kulimba kwa matope.

Kupititsa patsogolo ntchito: HPMC ikhoza kupangitsa kuti matope awonetsere bwino madzimadzi pansi pa mphamvu yochepetsera, zomwe zimapangitsa kuti zikhale zosavuta kugwiritsa ntchito ndi msinkhu; pamene pansi pa kumeta ubweya wambiri mphamvu, matope amasonyeza kukhuthala kwapamwamba, kuteteza kugwedezeka ndi kuyenda. . thixotropy wapadera umenewu umapangitsa kuti matope azikhala osalala panthawi yomanga, kuchepetsa zovuta zomanga ndi kuwonjezereka kwa ntchito.

Limbikitsani kukana kwa ming'alu: Powonjezera zotanuka modulus ndi kulimba kwa matope, HPMC imatha kuchepetsa kuchitika kwa ming'alu, kukonza kukana kwa matope, ndikukulitsa moyo wake wautumiki.

Kuwonjezeka kwamphamvu kwamphamvu: HPMC imawonjezera mphamvu yosunthika yamatope polimbitsa matrix ndikuwongolera kulumikizana pakati pa tinthu tating'onoting'ono. Izi zidzakulitsa kukana kupsinjika kwakunja ndikuwonetsetsa kukhazikika kwanyumbayo.

Mphamvu yomangirira: HPMC imapanga filimu yopyapyala mozungulira tinthu ting'onoting'ono, kuwongolera kulumikizana pakati pa matope ndi gawo lapansi. Kumamatira kumeneku kumatsimikizira mgwirizano wamphamvu, kuchepetsa chiopsezo cha delamination kapena kulephera.

Kukhazikika kwamphamvu: Kuphatikizidwa kwa HPMC kumatha kupanga zida zopepuka, ndikuchepetsa kulemera kwa 11.76%. Chiyerekezo chopanda kanthu choterechi chimathandiza ndi kutchinjiriza kwamafuta, kuchepetsa mphamvu yamagetsi yazinthu mpaka 30% ndikusunga kutentha kosasunthika kwa pafupifupi 49W kukakhala ndi kutentha komweko. Kukaniza kusuntha kutentha kudzera pagululi kumasiyanasiyana ndi kuchuluka kwa HPMC yowonjezeredwa, ndikuphatikizidwa kwakukulu kwa zowonjezera zomwe zimapangitsa kuti 32.6% ichuluke kukana kwamafuta poyerekeza ndi kusakaniza komwe kumatchulidwa.

Chepetsani Kutsika ndi Kusweka: Kutsika ndi kung'ambika ndizovuta zomwe zimachitika pamakina opangira matope, zomwe zimapangitsa kuti pakhale kukhazikika. HPMC imapanga matrix osinthika mkati mwa matope, kuchepetsa kupsinjika kwamkati ndikuchepetsa kuchitika kwa ming'alu ya shrinkage.

Kupititsa patsogolo kukana kwamadzi ndi kusasunthika: Mu drywall ndi caulk, HPMC imakulitsa kukana kwa madzi ndi kusasunthika, kukhalabe bata m'malo achinyezi ndikukulitsa moyo wazinthuzo.

Limbikitsani kukana kuzizira: Chifukwa chakusunga bwino madzi komanso kukana kwa ming'alu, HPMC imatha kukhalabe yokhazikika m'malo ovuta kwambiri, kuwonetsetsa kuti matope amamanga bwino komanso kulimba kwake.

Limbikitsani mphamvu zomangirira: HPMC imathanso kukulitsa mphamvu yomangirira-kumeta ubweya wamatope. Kuwonjezera 0.2% HPMC kumatha kuwonjezera mphamvu yomangirira yamatope kuchokera ku 0.72MPa kupita ku 1.16MPa.

HPMC imakhudza kwambiri kukhazikika kwa matope. Ikhoza kupititsa patsogolo kasungidwe ka madzi mumatope, kupititsa patsogolo kugwira ntchito, kupititsa patsogolo kukana kwa ming'alu, kulimbitsa mphamvu zomangira, kupititsa patsogolo kulimba, kuchepetsa kuchepa ndi ming'alu, komanso kumapangitsa kuti madzi asawonongeke komanso kuti asawonongeke. katundu, kupititsa patsogolo kuuma-thaw kukana komanso kupititsa patsogolo mphamvu zomangirira. Zinthu izi zimapangitsa HPMC kukhala chowonjezera chofunikira pakuwongolera kulimba kwa matope.
