Kugwiritsa ntchito hydroxypropyl methylcellulose mu putty powder

Putty ndi mtundu wa zipangizo zokongoletsera zomangira. Chovala choyera pamwamba pa chipinda chopanda kanthu chomwe changogulidwa nthawi zambiri chimakhala choyera kuposa 90 ndi kupitilira 330 mu fineness. Putty imagawidwa kukhala khoma lamkati ndi khoma lakunja. Kunja kwa khoma putty kuyenera kukana mphepo ndi dzuwa, chifukwa chake imakhala ndi guluu wapamwamba, mphamvu yayikulu komanso index yotsika pang'ono yoteteza chilengedwe. Mlozera wokwanira wa khoma lamkati la putty ndi wabwino, wathanzi komanso chitetezo cha chilengedwe, kotero khoma lamkati silimagwiritsidwa ntchito kunja ndipo khoma lakunja siligwiritsidwa ntchito mkati. Kawirikawiri putty ndi gypsum kapena simenti, kotero pamwamba pake ndi yovuta komanso yosavuta kugwirizanitsa mwamphamvu. Komabe, pakumanga, ndikofunikira kugwiritsa ntchito wosanjikiza wothandizila pamawonekedwe oyambira kuti asindikize njira yoyambira, ndikuwongolera kumamatira kwa khoma, kuti putty ikhale yolumikizidwa bwino pamunsi.

Kuchuluka kwa HPMC komwe kumagwiritsidwa ntchito kumadalira nyengo ya nyengo, kusiyana kwa kutentha, khalidwe la ufa wa calcium phulusa, Chinsinsi chachinsinsi cha putty powder ndi "khalidwe lofunika ndi woyendetsa". Nthawi zambiri, pakati pa 4kg ndi 5kg.

HPMC ili ndi ntchito yothira mafuta, yomwe ingapangitse ufa wa putty kukhala ndi ntchito yabwino. Hydroxypropyl methylcellulose satenga nawo gawo pazotsatira zilizonse, koma zimakhala ndi zotsatira za chithandizo. Putty ufa ndi mtundu waposachedwa pamadzi komanso pakhoma,

Mavuto ena:

1. Kuchotsa ufa wa putty

A: Izi zikugwirizana ndi mlingo wa laimu calcium, komanso zokhudzana ndi mlingo ndi khalidwe la cellulose, zomwe zikuwonetsedwa mu mlingo wosungira madzi wa mankhwala. Mlingo wosungira madzi ndi wotsika ndipo nthawi ya hydration ya laimu calcium sikokwanira.

2. Peeling ndi kupukuta ufa wa putty

A: Izi zikugwirizana ndi kuchuluka kwa kusunga madzi. Ma cellulose viscosity ndi otsika, omwe ndi osavuta kuchitika kapena mlingo wake ndi wochepa.

3. Mfundo ya singano ya putty powder

Izi zimagwirizana ndi cellulose, yomwe ili ndi katundu wosapanga mafilimu. Pa nthawi yomweyo, zosafunika mu mapadi ndi pang`ono anachita ndi phulusa calcium. Ngati yankho liri lamphamvu, ufa wa putty udzawonetsa mkhalidwe wa zotsalira za tofu. Izo sizingakhoze kupita kukhoma ndipo ziribe mphamvu yomangirira. Kuphatikiza apo, imapezekanso muzinthu monga magulu a carboxy osakanikirana ndi cellulose.
