Kodi kusungidwa kwa madzi kwa hydroxypropyl methylcellulose kudzakhala kosiyana munyengo zosiyanasiyana?

Cellulose ether hpmc imakhala ndi ntchito yosunga madzi ndikuwonjezera mumatope a simenti ndi matope a gypsum, omwe amatha kusintha bwino kumamatira ndi kukana kosunthika kwa zinthu zamatope.

Zinthu monga kutentha kwa gasi, kutentha ndi kuthamanga kwa mpweya zimawononga kwambiri kuchuluka kwa chinyezi kuchokera kumatope a simenti ndi gypsum. Chifukwa chake, pali kusiyana kwina pakuwonjezera kuchuluka kwazinthu za HPMC kuti musunge madzi moyenera munyengo iliyonse.

Pothira konkriti, mphamvu yotsekera madzi imatha kusinthidwa ndikuwonjezera ndikuchepetsa kutuluka kwagawo. Mlingo wosungira madzi wa methyl cellulose ether pa kutentha kwakukulu ndiye mtengo wofunikira wosiyanitsa mtundu wa methyl cellulose ether.

Mankhwala apamwamba a HPMC amatha kuthetsa vuto la kutseka kwa madzi otentha kwambiri. M'nyengo yotentha kwambiri, makamaka m'madera otentha ndi amvula komanso kumanga chromatography, HPMC yapamwamba imafunika kuti madzi asungidwe bwino.

HPMC yapamwamba kwambiri imakhala yofanana kwambiri, ndipo magulu ake a methoxyl ndi hydroxypropyl amagawidwa mofanana pamagulu a cellulose, omwe amatha kupititsa patsogolo mphamvu ya mamolekyu a okosijeni kuti apange covalent bond pa hydroxyl ndi ether bond.

Ikhoza kulamulira bwino kutuluka kwa madzi chifukwa cha nyengo yotentha ndikukhala ndi mphamvu yotseka madzi. Wapamwamba methylcellulose HPMC angagwiritsidwe ntchito matope osakaniza ndi pulasitala wa luso Paris.

Gwirizanitsani tinthu tating'onoting'ono tolimba kuti tipange filimu yonyowa, ndipo chinyezi m'chizoloŵezicho chidzatulutsidwa pang'onopang'ono kwa nthawi yaitali, ndikuchitapo kanthu ndi zinthu zakuthupi ndi zinthu za collagen kuti zitsimikizire mphamvu zomangirira ndi mphamvu zowonongeka.

Choncho, m'nyengo yotentha yomanga malo, kuti tikwaniritse zotsatira za kupulumutsa madzi, tiyenera kuwonjezera mankhwala apamwamba a HPMC malinga ndi Chinsinsi, mwinamwake, zidzayamba chifukwa cha kusowa kwa kulimba, kuchepetsa mphamvu, kusweka, ng'oma ya gasi. ndi zovuta zina zamtengo wapatali. Zimayambitsa kuuma msanga.

Izi zimawonjezeranso vuto la zomangamanga kwa ogwira ntchito. Pamene kutentha kumachepa, kuchuluka kwa HPMC yowonjezeredwa kumachepa pang'onopang'ono kuti akwaniritse chinyezi chomwecho.
