Hydroxypropyl methylcellulose ndi gawo la simenti

HPMC ndi simenti

01
Matope oyendetsa matope, omwe amadziwika chifukwa chopangidwa ndi zopangira ndi zolemera 300-50, ma cacium carbider 20-5, calcium hydroxide ufa 10-20, bround Brown Pofa 10-12, yowuma mzindawo ufa wa utoto 30-25, dothi la aluminium sulfate 4 -6, ma carboxymethyl starch ufa wa 4-6, madzi 600-650; Izi zimathandizira madzi amtunduwu mafuta zamagetsi zokutira zimalimba kutentha, moto wabwino kutsutsana ndi khoma. Mphamvu yomukuza, magwiridwe antchito, kukana bwino, kutetezedwa kwabwino kwachilengedwe, kukana bwino chilengedwe, kukana, kukana, komanso kutsutsa.

Masiku ano, kodi mawidwe a hydroxypypyll methylcellulose yankho?

1. Mphunzitsi wambiri wa cellulose ether, kutentha kwa yankho, kudula, ndi njira yoyesera;

2. Kutentha kwagalu kumayenda, kutentha kwakukulu kwa kambiri, ndi mamasukidwe apamwamba a yankho;

3. Wokwera kwambiri wa cellulose ether, mafayilo a yankho lake. Chifukwa chake, tiyenera kulabadira kuchuluka koyenera mukakhazikitsa pulogalamu yoletsa mlingo woti ukhale wokwera kwambiri, womwe umakhudza mwachindunji matope ndi simenti ndi simenti. Khalidwe;

4. Monga zothetsera zambiri, mafanowo adzachepetsa ndi kuchuluka kwa kutentha. Kuphatikiza apo, okwera kwambiri a cellulose ether, ndiye kuti amapweteketsa kutentha; Kuphatikiza apo, kusinthasintha kwenikweni kumasiyananso malinga ndi kumwa madzi simenti ya epoxy.
