HPMC (hydroxypypyl methylcellulose) ndi mankhwala ofunikira mankhwala omwe amagwiritsidwa ntchito kwambiri m'matayala. Ndiwosagwira etherose ether, yomwe imapezeka ndi mankhwala a cellulose.
1. Kusunga kwamadzi
Ntchito yayikulu ya HPMC ndikuwongolera chitetezo chamadzi cha matope. Izi zikutanthauza kuti nthawi youmitsa matope, madziwo sadzatayika mwachangu, koma adzatsekedwa m'tato, potero amataya nthawi ya simenti ndikusintha mphamvu ya simenti. Izi ndizofunikira kwambiri mu malo owuma, otentha, komwe kutaya madzi mwachangu kumatha kuyambitsa matope ndikutaya mphamvu. HPMC imatha kuchepetsa madzi ndikupanga filimu yowiritsa, ndikuonetsetsa kuti simenti ilibe hydration kwathunthu ndikuwongolera mayendedwe onse a matope.
2. Kupititsa patsogolo mgwirizano
HPMC imathanso kusintha kwambiri matope. Zimapereka matope abwinoko, ndikupanga kukhala kosavuta komanso kosavuta kufalitsa mukamagwiritsa ntchito olimbitsa thupi pantchito yomanga. Nthawi yomweyo, hpmc imatha kukonzanso kukana kwa zivuta, ndiye kuti, matope sadzazungulira akamagwiritsa ntchito pamakoma kapena malo ena ofukula, omwe ndi oyenera kuti awonetsetse bwino.
3. Mode
Kutonthoza, HPMC imathandiziranso kutsatira. Zimatha kukonza mphamvu yolumikizana pakati pa matope ndi zinthu zam'munsi (monga njerwa, mwala kapena konkriti), potengera kuchitika kwa mavuto monga mabowo ndikugwa. HPMC imatsimikizira kuti matope amatha kutsatira maziko oyambira atamangidwa pomanga coutheon ndi kutsatira matope.
4..
HPMC imatha kukonza kwambiri chosokoneza matope. Panthawi youmitsa matope, kupsinjika mtima kuchitika kumachitika chifukwa cha mankhwala opatsirana. Makamaka kutayika kwa madzi kumatha msanga, kupsinjika uku kungayambitse matope. HPMC imachepetsa shrader shrament mwa kukhala chinyezi choyenera, potero kuchepetsa ming'alu. Kuphatikiza apo, zimapangitsa kusintha kwa matope, kukonzanso chiopsezo cha kusweka.
5. Chepetsa nthawi
HPMC imatha kuchedwetsa nthawi ya matope, yomwe ndi yopindulitsa kwambiri pamavuto enaake. Mwachitsanzo, m'masamba otentha kapena owuma, matope amakhazikika mwachangu, omwe angapangitse kuti asunthire kapena kulimbikitsa mkhalidwe womanga kuti uwonongeke. Posintha nthawi yokhazikika, hpmc imapereka nthawi yomanga nthawi yambiri kuti asinthe ndikugwiritsira ntchito ntchito, kukonza kusinthasintha ndi kovomerezeka pakumanga.
6. Kupititsa patsogolo chisanu
HPMC imatha kukonzanso chisanu cha matope. M'masamba ozizira, matope osakwanira adzaungula ngati kutentha kwa kutentha pang'ono, kumakhudza mphamvu ndi kukhazikika kwake. HPMC imathandizira kukana matope a matope ndikuchepetsa kusamuka ndi kuzizira kwa chinyezi chamkati.
7. Kuteteza zachilengedwe ndi chitetezo chachilengedwe
Hpmc ndi zowonjezera zachilengedwe komanso zowonjezera. Popeza zimachotsedwa ku cellulose yachilengedwe ndikusinthidwa mwanjira yamadzimu, sikuti ndi poizoni, yopanda vuto komanso zachilengedwe. Izi zimapangitsa kuti hommc yodziwika bwino kwambiri mu malonda omanga, makamaka pamapulojekiti omwe amafunikira kukwaniritsa miyezo yachilengedwe.
8. Kugwiritsa ntchito mitundu yosiyanasiyana yamativa
Malinga ndi mitundu yosiyanasiyana ya matope (monga matayala amandalama, ndikuyika matope, odzilimbitsa okha, ndi zina. Mwachitsanzo, m'matayala amtundu wa ceramic, hpmc amagwiritsidwa ntchito kwambiri kutsimikizira kukhazikika kwa matayala a ceramic pokonza ndi kukana; Mu zodzikongoletsera zokha, HPMC imagwiritsidwa ntchito kusinthitsa madzi ndi kusungidwa kwamadzi kuti mutsimikizire kuti matopewo amatha kufalikira komanso motero.
Kugwiritsa ntchito HPMC mu matope omanga ndi magawo ambiri. Sizingathandize kusintha matope omanga matope, komanso kusintha kulimba ndikugwiritsa ntchito matope. Chifukwa cha ntchito yake yapadera ndi mankhwala, hpmc yakhala yofunika kwambiri komanso yofunika kwambiri yopanga zinthu zamakono zomanga.
