Kusintha kwa HPMC kumachitika pazinthu za simenti

Hydroxypropyl methylcellulose (hpmc)ndi ma etheelose osungunuka osakhazikika a cellulose omwe amagwiritsidwa ntchito kwambiri m'munda womanga, makamaka pazida zamimenti. Monga owonjezera ogwiritsira ntchito, Kimacell®hpmc imatha kukonza zomwe zidapangidwa ndi simenti pogwiritsa ntchito njira zakuthupi ndi mankhwala, ndikusintha mphamvu, makina ake.

1. Sinthani ntchito zomanga

Zotsatira zazikulu kwambiri za HPMC ndikuwongolera magwiridwe antchito a simenti. Mwa kusintha mafayilo a simenti paste, hpmc amatha kusintha kwambiri ku kugwiritsidwa ntchito kwa zinthuzo, kumapangitsa kufalitsa ndi kungofalikira, ndikuchepetsa kutsika kwamadzi nthawi yomanga. Makamaka pamatongani odzilimbitsa okha, hpmc amatha kuyendetsa bwino madzi ndi madzi osungira madzi, kuletsa phala kuti lisagwedezeke kapena kukwapula pomanga, potero ndikuwonetsetsa kuti nthaka ikhale. Kuphatikiza apo, HPMC imakhalanso yothira bwino kwambiri, yomwe imatha kuchepetsa mikangano pakati pa zida zomangira ndi zida, kukonzanso kukonza njira yomanga.

2. Sinthani kusungidwa kwamadzi

HPMC imagwira gawo la mankhwala olimba omwe ali ndi zida zamiyeso. Magulu a hydrophilic mu mawonekedwe ake amathetsa madzi ambiri ndikuchedwetsa madzi. Kuchuluka kwa madzi ndikofunikira pakuthandizira kwa zinthu za simenti. Kumbali imodzi, hpmc imatha kupitirira nthawi yotsiriza ndi yomaliza ya slurry ndikupereka malo olimbitsa thupi okwanira tinthu tosiyanasiyana; Kumbali inayi, kuchuluka kwake kwa madzi kumatha kuchepetsa ngozi ya kuwononga kochepa ndikusintha kukula kwa zinthuzo panthawi yolimbana. Kutentha kwakukulu kapena chinyezi chochepa madera, madzi osungirako a HPMC ndiwofunika kwambiri, omwe amatha kusintha mavuto abwino obwera chifukwa cha zinthu zachilengedwe.

3. Sinthani magwiridwe antchito

HPMC ili ndi zolumikizana bwino ndipo zimatha kusintha chotsatira pakati pa zinthu za simenti ndi magawo. Zojambula monga zomata za tiile ndi maphepo maphewa, kuwonjezera kwa HPMC kumawonjezera mphamvu ya zinthuzo ndikuwonetsetsa kuti kukhazikika kwawo pakugwiritsa ntchito nthawi yayitali. Kuphatikiza apo, hpmc amathanso kupanga filimu yowonda pamwamba pa matope, kukonzanso nyengo yolimba ndi kukhazikika kwa matope.

4. Sinthani mphamvu zamakina

Ngakhale hpmc ndi zinthu zachilengedwe zokhala ndi polymer ndi kuchuluka kwake nthawi zambiri zimakhala zazing'ono, zimakhudzanso zochitika zamakina za zinthu za simenti. HPMC imatha kukonza microstruction ya slurry ndikupanga zinthu zamagetsi zogawika kwambiri, potero kukonza mphamvu yolemetsa ndi kuthekera kwa zinthu. Kuphatikiza apo, zoopsa za HPMC zimathandizanso kuchepetsa kufooka kwa zinthuzo ndikusintha kukhazikika kwake.

5. Zolemba

Ntchito zothandiza,HpmcAmagwiritsidwa ntchito kwambiri pakudzilimbitsa nokha, matayala omata, matope a matope, zofukitsira zopanda madzi ndikukonza zopangira. Mwachitsanzo, matope odzichepetsa, kuwonjezera kwa HPMC kumatha kusintha madzimadzi ndi magwiridwe antchito; Pa tile zomata za matabwa, kusungidwa kwa madzi kwa HPMC ndi katundu wogwirizanitsa kutsimikiziridwa kuti amalimbikitsa; Mu zophimba zosagwedero, hpmc zimatha kupereka madzi osungira komanso kukula kwake, potero kukonza magwiridwe antchito a chimbudzi.

Monga chowonjezera chowonjezera, hydroxypropyl methylcelluloulose imagwira gawo lofunikira pakuwongolera zinthu za simenti. Mwa kukonza zomangamanga, kukonza njira yamadzi, kukulitsa kulumikizana ndi kukonza zinthu, KIMAYILPMPC imathandizira kukonza maluso osintha magwiridwe antchito. Mu kafukufuku wamtsogolo ndi ntchito, makina ogwirira ntchito ndi njira yopangira HPMC munjira zosiyanasiyana zitha kufunsidwa kuti mukwaniritse mtengo wothandiza kwambiri.
