Popanga ndi kugwiritsa ntchito ufa wa putty, tidzakumana ndi mavuto osiyanasiyana. Lero, zomwe tikulankhula ndi zakuti ufa wa putty ukasakanizidwa ndi madzi, mukasakaniza kwambiri, putty imakhala yopyapyala, ndipo vuto la kulekanitsa madzi lidzakhala lalikulu.
Chifukwa chachikulu cha vutoli ndichakuti hydroxypropyl methylcellulose yomwe yawonjezeredwa mu ufa wa putty si yoyenera. Tiyeni tiwone mfundo yogwirira ntchito ndi momwe tingathetsere vutoli.
Mfundo yakuti ufa wa putty ukhale wochepa thupi kwambiri:
1. Kukhuthala kwa hydroxypropyl methylcellulose sikusankhidwa bwino, kukhuthalako kumakhala kochepa kwambiri, ndipo mphamvu yoyimitsidwa sikokwanira. Panthawiyi, kulekanitsidwa kwakukulu kwa madzi kudzachitika, ndipo mphamvu yoyimitsidwa yofanana sidzawonekera;
2. Onjezani chosungira madzi ku ufa wa putty, womwe umakhala ndi mphamvu yabwino yosungira madzi. Putty ikasungunuka ndi madzi, imatseka madzi ambiri. Panthawiyi, madzi ambiri amasungunuka m'magulu amadzi. Mukasakaniza madzi ambiri, amalekanitsidwa, choncho vuto lofala ndilakuti mukasakaniza kwambiri, zimakhala zoonda kwambiri. Anthu ambiri akumana ndi vutoli, mutha kuchepetsa bwino kuchuluka kwa cellulose wowonjezera kapena kuchepetsa madzi owonjezera;
3. Ili ndi ubale winawake ndi kapangidwe ka hydroxypropyl methylcellulose ndipo ili ndi thixotropy. Chifukwa chake, mukawonjezera cellulose, chophimba chonsecho chimakhala ndi thixotropy inayake. Putty ikasunthidwa mwachangu, kapangidwe kake konsekonse kamabalalika ndikukhala kopyapyala komanso kowonda, koma ikasiyidwa chete, imachira pang'onopang'ono.
Yankho: Mukagwiritsa ntchito ufa wa putty, nthawi zambiri onjezerani madzi ndikusakaniza kuti afike pamlingo woyenera, koma mukawonjezera madzi, mupeza kuti madzi ambiri akawonjezeredwa, amakhala ochepa. Kodi chifukwa chake ndi chiyani?
1. Cellulose imagwiritsidwa ntchito ngati chokhuthala komanso chosungira madzi mu ufa wa putty, koma chifukwa cha thixotropy ya cellulose yokha, kuwonjezera kwa cellulose mu ufa wa putty kumabweretsanso thixotropy mutawonjezera madzi mu putty;
2. thixotropy iyi imachitika chifukwa cha kuwonongeka kwa kapangidwe kake ka zinthu zomwe zili mu ufa wa putty. Kapangidwe kameneka kamapangidwa pakapuma ndikuchotsedwa pansi pa kupsinjika, ndiko kuti, kukhuthala kumachepa mukasakaniza, ndipo kukhuthala pakapuma Kubwezeretsa, kotero padzakhala chodabwitsa kuti ufa wa putty umakhala wochepa thupi ukawonjezeredwa ndi madzi;
3. Kuphatikiza apo, ufa wa putty ukagwiritsidwa ntchito, umauma mofulumira kwambiri chifukwa kuwonjezera kwambiri ufa wa calcium wa phulusa kumagwirizana ndi kuuma kwa khoma. Kusenda ndi kuzunguliza kwa ufa wa putty kumagwirizana ndi kuchuluka kwa madzi omwe amasungidwa;
4. Chifukwa chake, kuti tipewe zinthu zosafunikira, tiyenera kusamala ndi mavuto amenewa tikamagwiritsa ntchito.
