Ubale Pakati pa Viscosity ndi Kutentha kwa Hydroxypropyl Methylcellulose (HPMC)

(1) Kutsimikiza kwaMtengo wa HPMCmamasukidwe akayendedwe: Zouma zowuma zimakonzedwa mu njira yamadzimadzi yokhala ndi kulemera kwa 2 °C, ndipo amayezedwa ndi mtundu wa NDJ-1 wozungulira viscometer;

(2) Maonekedwe a chinthucho ndi ufa, ndipo nthawi yomweyo amalembedwa ndi "s" mu dzina lachidziwitso.

Momwe mungagwiritsire ntchito hydroxypropyl methylcellulose?

Imawonjezedwa mwachindunji panthawi yopanga.Njira imeneyi ndi yosavuta komanso yaifupi kwambiri yowononga nthawi.Masitepe enieni ndi awa:

1. Onjezerani madzi enaake otentha ku chotengera chogwedeza ndi kumeta ubweya wambiri (mankhwala a hydroxyethyl cellulose amasungunuka m'madzi ozizira, choncho 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 ozizira okwanira ndipo pitirizani kusonkhezera mpaka zinthu zonse zitasungunuka kwathunthu (kuwonekera kwa yankho mwachiwonekere kukuwonjezeka);

5. Kenaka yikani zosakaniza zina mu fomula.

Konzekerani mowa wa amayi kuti mugwiritse ntchito: Njira iyi ndi yokonzekera mowa kukhala chakumwa chochuluka, kenako ndikuchiwonjezera pa mankhwalawo.Ubwino wake ndikuti umakhala ndi kusinthasintha kwakukulu ndipo ukhoza kuwonjezeredwa mwachindunji ku mankhwala omalizidwa.Masitepe ndi ofanana ndi (1-3) mu njira yowongoka mwachindunji.Chogulitsacho chikanyowa kwambiri, chisiyeni kuti chiyime kuti kuziziritsa kwachilengedwe kusungunuke, ndikuyambitsanso musanagwiritse ntchito.Tiyenera kuzindikira kuti antifungal wothandizira ayenera kuwonjezeredwa kwa mowa wa amayi mwamsanga.

Kugwiritsa ntchito kusakaniza kouma: Mukatha kusakaniza ufa ndi zipangizo za ufa (monga simenti, gypsum powder, dongo ladongo, ndi zina zotero), onjezerani madzi okwanira, ndikuphwanya 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 itasungunuka kwathunthu.

Kusamala pokonzekera njira zothetsera mavuto

(1) Zogulitsa popanda mankhwala apamwamba (kupatula hydroxyethyl cellulose) sizidzasungunuka mwachindunji m'madzi ozizira;

(2) Iyenera kusefedwa pang'onopang'ono mu chidebe chosakaniza, ndipo musawonjezere mwachindunji mankhwala omwe apangidwa kukhala chipika mu chidebe chosakaniza mochuluka;

(3) Mtengo wa pH wa kutentha kwa madzi ndi madzi uli ndi ubale wofunikira ndi kusungunuka kwa mankhwala, ndipo chidwi chapadera chiyenera kuperekedwa;

(4) Osawonjezera zinthu zamchere kusakaniza ufa usanalowedwe ndi madzi, ndikuwonjezera pH mtengo mutatha kuthira, zomwe zingathandize kusungunuka;

(5) Momwe mungathere, onjezerani antifungal wothandizira pasadakhale;

(6) Pogwiritsira ntchito mankhwala apamwamba-makamaka, kulemera ndende ya mowa mayi sayenera kukhala apamwamba kuposa 2.5-3%, apo ayi mowa mayi n'kovuta ntchito;

(7) Zogulitsa zomwe zakhala zikuthandizidwa pompopompo sizigwiritsidwa ntchito muzakudya kapena mankhwala.
