Popanga ndi kugwiritsa ntchito ufa wopanda pake, tidzakumana ndi mavuto osiyanasiyana. Masiku ano, zomwe tikukambirana ndikuti ufa wa punty umasakanizidwa ndi madzi, momwe mumakonzera kwambiri, owonda amakhala, ndipo chodabwitsa cha kudzipatula kwa madzi chidzakhala chovuta.
Choyambitsa vutoli ndikuti hydroxypropyll methylcellulose yowonjezeredwa mu ufa wa putty suyenera. Tiyeni tiwone mfundo yogwira ntchito ndi momwe tingachiritsire.
Mfundo ya putty ufa wokhala wocheperako komanso wowonda:
1. Makulidwe a hydroxypropyll methylclulose yosankhidwa, ma viwawo ndi otsika kwambiri, ndipo zotsatira zoyipa sizokwanira. Pakadali pano, kulekanitsidwa kwamadzi kwambiri kudzachitika, ndipo kusintha kwa yunifolomu sikuwonekera;
2. Onjezerani wothandizira wa madzi kuti asungunukitse ufa, womwe uli ndi mphamvu yabwino. Pamene putty imasungunuka ndi madzi, imatseka madzi ambiri. Pakadali pano, madzi ambiri ali okonzedwa m'magulu am'madzi. Ndi oyambitsa madzi ambiri amalekanitsidwa, kotero vuto wamba ndikuti mukuyambitsa, kuwonda kumakhala. Anthu ambiri akumana ndi vutoli, mutha kuchepetsa kuchuluka kwa cellulose kapena kuchepetsa madzi owonjezera;
3. Ilinso ndi ubale winawake ndi kapangidwe ka hydroxpyupyl methylcellulose ndipo ali ndi thixotropy. Chifukwa chake, mutatha kuwonjezera cellulose, zokutidwa konse zimakhala ndi thixotropy ina. Mateyo atawomberedwa mwachangu, mawonekedwe ake onse adzabalana ndipo amakhala wocheperako komanso wowonda, koma akasiyidwa, pang'onopang'ono chimachira.
Yankho: Mukamagwiritsa ntchito ufa wa putty, nthawi zambiri kuwonjezera madzi ndikuyambitsa kuti zifike pamlingo woyenera, koma powonjezera madzi, mupeza kuti madzi ambiri amawonjezeredwa, wowonda amakhala. Kodi chifukwa chake ndi chiyani?
1. Cellulose imagwiritsidwa ntchito ngati wophunzitsira ndi madzi osungira madzi pansi, koma chifukwa cha chixotropy wa cellulose wokha, koma kuwonjezera kwa cellulose mu ufa kufinyanso kuphika madzi.
2. Thixotropy iyi imayambitsidwa ndi kuwonongeka kwa kapangidwe kazinthu zomwe zimaphatikizidwa mwapadera mu ufa. Kapangidwe kameneka kamapangidwa ndikukhumudwa kwambiri, ndiye kuti, chidwi chimachepa pansi pa kusungunuka, motero padzakhala chinthu chochepa kuti ufa ufa umakhala wocheperako monga umawonjezeredwa ndi madzi;
3. Kuphatikiza apo, pamene putty ufa ukugwiritsidwa ntchito, umawuma mwachangu chifukwa kuwonjezera kwambiri kwa Ash calcium kufalikira, ndipo kuseka ndi kugubuduza ufa wogwirizana ndi malo osungirako madzi ;
4. Chifukwa chake, pofuna kupewa zochitika zosafunikira, tiyenera kulabadira mavutowa mukamagwiritsa ntchito.
Tikamagwiritsa ntchito ufa wa putty, nthawi zonse timakumana ndi mavuto amitundu yonse. Zachidziwikire, zilibe kanthu. Malingana ngati tikudziwa mfundo ndi yankho, titha kuletsa zinthu ngati izi kuti zisachitike.
