(1) Kutsimikiza kwa viscosity: zouma zouma zimakonzedwa mu njira yamadzimadzi yokhala ndi kulemera kwa 2 ° C, ndipo imayesedwa ndi ndj-1 viscometer yozungulira;
(2) Maonekedwe a mankhwalawo ndi a ufa. Mankhwala apompopompo amaphatikizidwa ndi "s" ndipo mankhwala amtundu wamankhwala amaphatikizidwa ndi "y". Mwachitsanzo, me-4000s ndi mankhwala a me-4000.
01. Momwe mungagwiritsire ntchito hydroxypropyl methylcellulose
Onjezani mwachindunji panthawi yopanga, njira iyi ndiyo njira yosavuta komanso yaifupi kwambiri yowonongera nthawi, njira zake ndi:
1. Onjezani kuchuluka kwa madzi otentha mumtsuko wosonkhezera wokhala ndi kumeta ubweya wambiri (mankhwala a hydroxyethyl cellulose amasungunuka m'madzi ozizira, ingowonjezerani madzi ozizira);
2. Yatsani kusonkhezera pang'onopang'ono, ndipo pang'onopang'ono sungani mankhwalawa mu chidebe choyambitsa;
3. Pitirizani kuyambitsa mpaka tinthu tating'onoting'ono tanyowa;
4. Onjezerani madzi okwanira okwanira ndipo pitirizani kusonkhezera mpaka zinthu zonse zitasungunuka kwathunthu (kuwonekera kwa yankho kumawonjezeka kwambiri);
5. Kenaka yikani zosakaniza zina mu ndondomekoyi.
Konzekerani mowa wamayi kuti mugwiritse ntchito: Njira iyi ndikupangitsa kuti chakumwacho chikhale chakumwa chochuluka kaye, kenako ndikuchiwonjezera. Ubwino wake ndikuti umakhala ndi kusinthasintha kwakukulu ndipo ukhoza kuwonjezeredwa mwachindunji ku mankhwala omalizidwa. Masitepewo ndi ofanana ndi masitepe (1-3) munjira yowongoka mwachindunji. Mankhwalawa akamanyowetsedwa bwino, mulole kuti aime kuti kuziziritsa kwachilengedwe kusungunuke, kenako ndikuyambitsanso musanagwiritse ntchito. Tiyenera kuzindikira kuti antifungal wothandizira ayenera kuwonjezeredwa kwa mowa wa amayi mwamsanga.
Kusakaniza kouma: mukatha kusakaniza ufa ndi zipangizo za ufa (monga simenti, gypsum powder, dongo la ceramic, etc.), onjezerani madzi okwanira, pondani ndi kusonkhezera mpaka mankhwalawo asungunuka kwathunthu.
Kusungunuka kwa madzi ozizira sungunuka mankhwala: madzi ozizira sungunuka mankhwala akhoza mwachindunji anawonjezera madzi ozizira kuvunda. Pambuyo powonjezera madzi ozizira, mankhwalawa adzamira mofulumira. Pambuyo pa kunyowa kwa nthawi inayake, yambani kugwedeza mpaka kusungunuka kwathunthu.
02. Njira zodzitetezera pokonzekera zothetsera
(1) Zogulitsa popanda mankhwala apamwamba (kupatula hydroxyethyl cellulose) sizidzasungunuka mwachindunji m'madzi ozizira.
(2) Iyenera kusefedwa pang'onopang'ono mu chidebe chosakaniza, osawonjezera mwachindunji kuchuluka kapena mankhwala omwe apanga chipika mu chidebe chosakaniza.
(3) Kutentha kwa madzi ndi ph mtengo wa madzi ali ndi ubale woonekeratu ndi kusungunuka kwa mankhwala, kotero chidwi chapadera chiyenera kulipidwa.
(4) Osawonjezera zinthu za alkaline kusakaniza ufa wa mankhwalawo usanawaviike ndi madzi. Kukweza pH pambuyo pakuviika kumathandizira kusungunuka.
(5) Momwe mungathere, onjezani antifungal wothandizira pasadakhale.
(6) Pogwiritsira ntchito mankhwala otsekemera kwambiri, kulemera kwa mowa wa amayi kuyenera kukhala kwakukulu kuposa 2.5-3%, apo ayi mowa wa amayi udzakhala wovuta kupirira.
(7) Zogulitsa zomwe zasungunuka nthawi yomweyo sizingagwiritsidwe ntchito muzakudya kapena mankhwala.
