Kugwiritsa ntchito hydroxyethyl cellulose mu simenti ndi khoma

Hydroxyethyl cellulose (hec) ndi polymer yofunikira polymer yomwe imagwiritsidwa ntchito pomanga. Chifukwa cha kukula kwake kwakukulu, kusungidwa kwamadzi komanso katundu wamafilimu, hec akuwonetsa kusintha kwa simenti ndi khoma.

1.Ccharacter of Hydroxethyl cellulose

Hydroxyethyl cellulose ndi ma cellulose omwe alibe mainchesi omwe adapeza polemba cellulose ndi ethylene oxide. Zinthu zake zazikulu zimaphatikizapo:
Kusungunuka kwamadzi: Hec imatha kusungunuka mwachangu m'madzi ozizira kuti apange madzi owoneka bwino.
Kukula: Hec imatha kuwonjezera mawonekedwe a yankho.
Kusungidwa kwamadzi: Kutha kuchedwetsa madzi osinthika, motero kumawongolera magwiridwe antchito.
Kuyimitsidwa: Hec ikhoza kuyimitsa ma tinthu tambiri ndikuletsa kukhazikika.
Katundu wopanga makanema: Hec yankho amatha kupanga filimu yowonekera bwino ndi kulimba mtima.
Zinthu izi zimapangitsa ma hydroxyethyl cellulose zowonjezera zowonjezera pomanga monga simenti ndi putty.

2. Kugwiritsa ntchito hydroxyethyl cellulose mu simenti

Sinthani magwiridwe antchito
M'magawo a CELONO Mwachitsanzo, panthawi yopaka kapena kupaka utoto, ma slormer a simenti adawonjezera ndi HeC kukhala ndi kugwirira ntchito bwino komanso kusungidwa kwamadzi. Zinthu izi zimalepheretsa nkhaniyo kuti zisafome msanga pomanga, potero kuchepetsa mapangidwe a ming'alu ndi kukonza mapangidwe omanga.

Sinthani kukana
Mphamvu yosungitsa madzi imathandizira kusungitsa chinyezi chogawa mu simenti cholimba ndikuchepetsa kupezekanso kwa ming'alu. Nthawi yomweyo, Hec amawonjezera mawilo a simenti slorry, kuloleza kuti ikulungidwe bwino ndikuthandizira okalamba, motero amalimbikitsa kukana kwa zinthu za simenti.

Sinthani Mode
Zovala za Hec zimatha kukonza mgwirizano pakati pa simenti ndi zinthu zina, monga simenti ndi njerwa kapena gulu la gypsum. Izi ndizofunikira kwambiri kukonza kukhazikika ndi kukhazikika kwa mawonekedwe onse.

3. Kugwiritsa ntchito hydroxyethyl cellulose m'khola

Kukula
M'MAPATT THETY, zotsatira za kukula kwa Hec zimapangitsa kuti patene akhale ndi mafayilo abwino, motero oyang'anira omanga. Kukula kwabwino kumapangitsa kuti pakhale mateni kuti agwiritsidwe ntchito pakhoma popanda kukwawa kapena kudzikundikira.

Sinthani kusungidwa kwamadzi
Mphamvu yosungitsa madzi ndiofunikira kuntchito yake yomanga. Hec amatha kuchedwetsa madzi kusintha ndikuwonetsetsa kuti chinyezi chili ndi chinyontho chokwanira panthawi yochiritsa pakuchirikiza, mwakutero kukonza mphamvu ndi kukhazikika kwa otentheka. Makamaka m'malo owuma, madzi osungira nkhuku amatha kusintha kwambiri magwiridwe antchito ndikupewa kuti zisafonge.

Sinthani Kugwirizana
Kugwiritsa ntchito Hec mu punty kumatha kusintha zinthu mosalala komanso kuwoneka bwino kwa nkhaniyo. Nthawi yomweyo, chifukwa chiyenga chimatha kuyimitsanso tinthu tating'onoting'ono tofana ndikuwalepheretsa kukhazikika, kukhazikika kumakhala kokhazikika panthawi yosungirako.

Sinthani bwino mawonekedwe
Hec amachita nawo mgwirizano wolumikizirana ndi makanema mu Detty, omwe amalola kuti chivundikirocho chizikhala chowoneka bwino ndi chofiyira atachiritsa. Pamwambapa siophweka mchenga, komanso amapereka zokongoletsera zabwino, ndikupereka maziko abwino operekera utoto wotsatira.

4. Kuwonjezera kuchuluka ndi kugwiritsa ntchito njira ya hydroxyethyl cellulose

Pamapulogalamu othandiza, kuphatikiza kwa hydroxyethyl cellulose nthawi zambiri kumayendetsedwa pakati pa 0,1% ndi 0,5%. Ndalama zomwe zimafunikira kuti zisasinthidwe molingana ndi zofunikira za zofunikira ndi kugwiritsa ntchito pulogalamuyi. Hec nthawi zambiri amawonjezeredwa ndi simenti kapena ma purty osakaniza mu ufa kapena mawonekedwe a granular. Kuonetsetsa kuti mukubalalika, nthawi zambiri imakhala yosakanikirana ndi madzi ochepa kuti apange yankho la colloidal musanasakanizidwe ndi zinthu zina.

5. Mukamagwiritsa ntchito Hec, muyenera kulabadira mfundo zotsatirazi:

Kusintha kwa Chipembedzo: Kufalikira kwa Hec kumakhudzidwa ndi kutentha kwa madzi komanso liwiro losangalatsa. Mukamagwiritsa ntchito madzi ozizira, moyenera zimakulitsa nthawi yosangalatsa kuonetsetsa kuti inclection ya Hec.
Kusakanikirana: Popewa kupindika kwa HEC, Hec kuyenera kusungunuka m'madzi kaye asanawonjezere zida zina.
Zoyenera kusungidwa: Hec iyenera kusungidwa m'malo owuma komanso ozizira, kutali ndi chinyezi kapena kutentha kwambiri.

6. Zolemba

khoma
Wam' khoma, kuwonjezera hec kumatha kusintha mosamala kapangidwe kake. Mwachitsanzo, polojekiti inayake, yowonjezera 0,2% Hec idawonjezera nthawi yogwira ntchito ndi mphindi 30, ndipo pamwamba pa zouma zake zinali zosalala komanso zopanda maziko, ndikupatsa maziko abwino opangira zopondera zotsatila.

simenti yodzilimbitsa
Pogwiritsa ntchito simenti yodzichepetsera, hec imatha kukonza mafayilo ndi kusungidwa kwamadzi kwa malo otsekemera, kulola simenti kuti ikhalebe madzi abwino komanso ofanana munthawi yodzikongoletsa. Mwachitsanzo, mu polojekiti ina ya nthaka, ndikuwonjezera 0,3% Hec moyenera kwambiri adasintha madzi ndi kuthekera kodzichiritsa kwa simenti slurry. Pambuyo pomanga, nthaka inali yosalala ndipo kunalibe ming'alu yowoneka bwino.

Monga zowonjezera zogwira ntchito kwambiri, hydroxethyl cellulose yawonetsa ntchito yotsatira imapangitsa simenti ndi khoma. Kusungidwa kwake, kusungidwa kwamadzi, komanso zotsatsa zosintha osati kukonza magwiridwe antchito a zinthuzo komanso zapamwamba, komanso makamaka kukana kwa zinthu zakuthupi ndi kulimba. Ndi chitukuko mosalekeza pomanga ukadaulo, Hec adzagwiranso ntchito yofunika kwambiri pakugwiritsa ntchito zinthu zakunyumba.
