Kodi mfundo ya ufa wa putty kukhala woonda komanso woonda ndi chiyani?

Popanga ndi kugwiritsa ntchito putty powder, tidzakumana ndi mavuto osiyanasiyana.Masiku ano, zomwe tikukambazi ndikuti pamene ufa wa putty umasakanizidwa ndi madzi, mukamagwedeza kwambiri, putty adzakhala wochepa kwambiri, ndipo chodabwitsa cha kulekanitsa madzi chidzakhala chachikulu.

Choyambitsa vutoli ndi chakuti hydroxypropyl methylcellulose yowonjezeredwa mu putty powder si yoyenera.Tiyeni tiwone mfundo yogwirira ntchito ndi momwe tingathetsere.

Mfundo ya ufa wa putty kukhala woonda komanso woonda:

1. Viscosity ya hydroxypropyl methylcellulose imasankhidwa molakwika, kukhuthala kwake kumakhala kochepa kwambiri, ndipo kuyimitsidwa sikukwanira.Panthawiyi, kulekanitsa kwakukulu kwa madzi kudzachitika, ndipo kuyimitsidwa kwa yunifolomu sikudzawonetsedwa;

2. Onjezerani wothandizira madzi ku ufa wa putty, womwe uli ndi zotsatira zabwino zosungira madzi.Putty ikasungunuka ndi madzi, imatseka madzi ambiri.Pa nthawi imeneyi, madzi ambiri flocculated mu masango madzi.Ndi kusonkhezera madzi ambiri amalekanitsidwa, kotero vuto lofala ndiloti mukamasonkhezera kwambiri, limakhala lochepa thupi.Anthu ambiri adakumana ndi vutoli, mutha kuchepetsa bwino kuchuluka kwa cellulose kapena kuchepetsa madzi owonjezera;

3. Imakhalanso ndi ubale wina ndi kapangidwe ka hydroxypropyl methylcellulose ndipo ili ndi thixotropy.Choncho, mutatha kuwonjezera cellulose, chophimba chonsecho chimakhala ndi thixotropy.putty ikagwedezeka mwachangu, mawonekedwe ake onse amabalalika ndikukhala ochepa komanso ochepa, koma ikasiyidwa, imachira pang'onopang'ono.

Yankho: Mukamagwiritsa ntchito ufa wa putty, nthawi zambiri onjezerani madzi ndi kusonkhezera kuti afike pamlingo woyenera, koma powonjezera madzi, mudzapeza kuti madzi ochulukirapo amawonjezeredwa, amakhala ochepa kwambiri.Chifukwa chiyani?

1. Ma cellulose amagwiritsidwa ntchito ngati thickener ndi madzi-agent wothandizira mu putty powder, koma chifukwa cha thixotropy wa cellulose mwiniwake, kuwonjezera pa cellulose mu putty powder kumabweretsanso thixotropy pambuyo powonjezera madzi ku putty;

2. thixotropy iyi imayamba chifukwa cha kuwonongedwa kwa chigawo chosakanikirana cha zigawo za putty powder.Kapangidwe kameneka kamapangidwa pa mpumulo ndikuphwanyidwa pansi pa kupsinjika, ndiko kunena kuti, kukhuthala kumachepa pansi pa kugwedezeka, ndi kukhuthala kwa mpumulo Kubwezeretsa, kotero padzakhala chodabwitsa kuti ufa wa putty umakhala wochepa kwambiri pamene umawonjezeredwa ndi madzi;

3. Kuonjezera apo, pamene ufa wa putty ukugwiritsidwa ntchito, umauma mofulumira chifukwa kuwonjezereka kwa phulusa la phulusa la calcium kumagwirizana ndi kuuma kwa khoma, ndipo kupukuta ndi kupukuta kwa putty powder kumakhudzana ndi kuchuluka kwa madzi osungira. ;

4. Choncho, kuti tipewe zinthu zosafunikira, tiyenera kulabadira mavutowa tikamagwiritsa ntchito.

Tikamagwiritsa ntchito putty powder, nthawi zonse timakumana ndi zovuta zachilendo.Inde, zilibe kanthu.Malinga ngati tikudziwa mfundo ndi njira yothetsera vutoli, tingapewe zimenezi.
