Ubale Pakati pa Kukhuthala ndi Kutentha kwa Hydroxypropyl Methyl Cellulose (HPMC)

(1) Kutsimikiza kwa kukhuthala: Chomera chouma chimakonzedwa kukhala madzi okhala ndi kulemera kwa 2°C, ndipo chimayesedwa ndi NDJ-1 rotational viscometer;

(2) Mawonekedwe a chinthucho ndi ufa, ndipo chinthucho nthawi yomweyo chimaphatikizidwa ndi "s".

Momwe mungagwiritsire ntchito hydroxypropyl methylcellulose

Onjezani mwachindunji panthawi yopanga, njira iyi ndiyo njira yosavuta komanso yaifupi kwambiri yotenga nthawi, masitepe enieni ndi awa:

1. Onjezani madzi otentha pang'ono mu chidebe chogwedezeka chokhala ndi mphamvu yayikulu yochepetsera kutentha (zopangidwa ndi hydroxyethyl cellulose zimasungunuka m'madzi ozizira, choncho onjezerani madzi ozizira);

2. Yatsani kusakaniza pa liwiro lotsika, ndipo pang'onopang'ono sefa chinthucho mu chidebe chosakaniza;

3. Pitirizani kusakaniza mpaka tinthu tonse titanyowa;

4. Onjezani madzi ozizira okwanira ndipo pitirizani kusakaniza mpaka zinthu zonse zitasungunuka kwathunthu (kuwonekera bwino kwa yankho kumawonjezeka kwambiri);

5. Kenako onjezerani zosakaniza zina mu fomula.

Konzani mowa wa amayi kuti mugwiritse ntchito: Njira iyi ndi yopangira mankhwalawa kukhala mowa wa amayi wokhala ndi kuchuluka kwakukulu kaye, kenako nkuwawonjezera ku chinthucho. Ubwino wake ndi wakuti ali ndi kusinthasintha kwakukulu ndipo akhoza kuwonjezeredwa mwachindunji ku chinthu chomalizidwa. Masitepewo ndi ofanana ndi masitepe (1-3) mu njira yowonjezera mwachindunji. Pambuyo poti chinthucho chanyowetsedwa mokwanira, chisiyeni kuti chiziziritse mwachilengedwe kuti chisungunuke, kenako chisakanize bwino musanagwiritse ntchito. Dziwani kuti mankhwala ophera tizilombo ayenera kuwonjezeredwa ku mowa wa amayi mwachangu momwe mungathere.

Kusakaniza kouma: Mukasakaniza ufa ndi zinthu za ufa (monga simenti, ufa wa gypsum, dongo la ceramic, ndi zina zotero) mutatha kuuma bwino, onjezerani madzi okwanira, sakanizani ndikusakaniza mpaka ufawo utasungunuka kwathunthu.

Kusungunuka kwa zinthu zosungunuka m'madzi ozizira: zinthu zosungunuka m'madzi ozizira zitha kuwonjezeredwa mwachindunji kumadzi ozizira kuti zisungunuke. Mukawonjezera madzi ozizira, chinthucho chidzamira mwachangu. Mukanyowa kwa nthawi inayake, yambani kusakaniza mpaka zitasungunuka kwathunthu.

Zosamala pokonzekera mayankho

(1) Zinthu zopanda mankhwala pamwamba (kupatula hydroxyethyl cellulose) siziyenera kusungunuka mwachindunji m'madzi ozizira;

(2) Iyenera kusefedwa pang'onopang'ono mu chidebe chosakaniza, musawonjezere mwachindunji kuchuluka kwakukulu kapena chinthu chomwe chapanga chipika mu chidebe chosakaniza;

(3) Kutentha kwa madzi ndi pH ya madzi zimaonekeratu kuti zikugwirizana ndi kusungunuka kwa chinthucho, choncho chisamaliro chapadera chiyenera kuperekedwa;

(4) Musawonjezere zinthu zina zamchere mu chisakanizocho musananyowetse ufa wa chinthucho ndi madzi, ndipo onjezerani pH mutanyowetsa, zomwe zingathandize kusungunuka;

(5) Momwe mungathere, onjezerani mankhwala ophera bowa pasadakhale;

(6) Mukamagwiritsa ntchito zinthu zokhala ndi kukhuthala kwakukulu, kuchuluka kwa mowa wochuluka wa mayi kuyenera kukhala kokwera kuposa 2.5-3%, apo ayi mowa wochuluka udzakhala wovuta kugwiritsa ntchito;

(7) Zinthu zomwe zasungunuka nthawi yomweyo siziyenera kugwiritsidwa ntchito muzakudya kapena mankhwala.
