Methyl Hydroxyethyl Cellulose Omwe Amagwiritsidwa Ntchito Pomanga

Methylhydroxyethylcellulose (MHEC) ndi ether yofunikira ya cellulose yomwe yakhala ikugwiritsidwa ntchito kwambiri pantchito yomanga chifukwa cha zinthu zake zabwino kwambiri. Mapangidwe oyambirira a MHEC ndikuyambitsa magulu a methyl ndi hydroxyethyl mu cellulose skeleton, yomwe imasinthidwa ndi mankhwala kuti ikhale ndi zinthu zapadera, monga kukhuthala, kusunga madzi, kumamatira ndi kupanga mafilimu.

thickening zotsatira

MHEC ili ndi zotsatira zabwino zokulitsa ndipo imatha kukulitsa kukhuthala kwa matope ndi zokutira. Pomanga, kukhuthala kwa matope kumakhudza mwachindunji ntchito yake yomanga ndi zotsatira zake zomaliza. Powonjezera kukhuthala kwa matope, MHEC imapangitsa kuti ikhale yochepa kwambiri ikagwiritsidwa ntchito ndipo imatha kuphimba khoma, kupititsa patsogolo ntchito yomanga ndi khalidwe. Kuonjezera apo, kuwonjezera MHEC ku zokutira kungalepheretse kupaka ndi kupukuta, kuonetsetsa kuti nsabwe za m'mimba zimakhala zofanana komanso zosalala.

kusunga madzi

Kusunga madzi ndi chimodzi mwazinthu zofunika kwambiri za MHEC muzomangamanga. Panthawi yomanga, chinyezi mumatope ndi konkire chimachepetsedwa mofulumira chifukwa cha evaporation ndi kuyamwa, zomwe zimapangitsa kuti mphamvu zakuthupi ziwonongeke komanso kusweka. MHEC imatha kusunga madzi moyenera, kukulitsa nthawi yonyowa yamatope ndi konkire, kulimbikitsa simenti yokwanira, ndikuwongolera mphamvu ndi kulimba kwa zinthuzo. Makamaka m'malo otentha kwambiri kapena owuma, ntchito yosungira madzi ya MHEC ndiyofunika kwambiri.

kugwirizana

MHEC ilinso ndi zida zabwino kwambiri zomangira ndipo imatha kulimbikitsa mgwirizano pakati pa matope ndi gawo lapansi. Mu zomatira za matailosi ndi zida zakunja zotchingira khoma, MHEC ngati chowonjezera imatha kupititsa patsogolo mphamvu zomangira zomatira ndikuletsa matailosi kuti asagwe komanso wosanjikiza wotsekereza kuti asagwe. Pogwiritsa ntchito moyenera MHEC popanga mapangidwe, kudalirika ndi moyo wautali wa zipangizo zomangira zingathe kutsimikiziridwa.

kupanga mafilimu

MHEC ili ndi zinthu zabwino zopanga mafilimu ndipo imatha kupanga filimu yoteteza yunifolomu pamwamba. Filimu yotetezayi imalepheretsa chinyezi kuti chisatuluke mwachangu komanso kumachepetsa ming'alu ndi kuchepa pamwamba pa zinthuzo. Mu zokutira zopanda madzi ndi zida zosindikizira, filimu yopanga filimu ya MHEC imatha kupititsa patsogolo kayendedwe ka madzi ndi kuonetsetsa kuti nyumbayo imatetezedwa ndi madzi. Pazipinda zodziyimira pawokha, MHEC imathanso kuwongolera kusalala komanso kusalala kwa pansi ndikupereka zokongoletsa zapamwamba kwambiri.

Ntchito zina

Kuphatikiza pa maudindo omwe ali pamwambawa, MHEC ilinso ndi ntchito zina zofunika pantchito yomanga. Mwachitsanzo, kuwonjezera MHEC popopera gypsum kumatha kupititsa patsogolo ntchito yomanga komanso kusalala kwa gypsum. Kunja kwa khoma putty, MHEC imatha kusintha kusinthasintha ndi kumamatira kwa putty ndikuletsa kusweka ndi kugwa. Kuphatikiza apo, MHEC itha kugwiritsidwanso ntchito ngati chokhazikitsira kuti pasakhale delamination ndi mpweya wa zinthu zomangira panthawi yosungira, kuwonetsetsa kukhazikika komanso kufanana kwa zida.

Mapulogalamu

Kuyika matailosi: Kuonjezera MHEC pazitsulo zomatira kumatha kuwonjezera nthawi yotsegulira ndi nthawi yosinthira zomatira, kupanga zomangamanga kukhala zosavuta, ndikuwonjezera mphamvu zomangirira ndikuletsa matailosi kugwa.

Njira yotchinjiriza kunja kwa khoma: MHEC ngati chowonjezera imatha kupititsa patsogolo kumamatira ndi kusunga madzi kwa matope otsekemera ndikupangitsa kuti zomangamanga zikhale zolimba komanso zolimba.

Pansi pawokha: Kuwonjezera MHEC pazida zodziyimira pawokha kumatha kupangitsa kuti madzi aziyenda pansi komanso kukhazikika pansi ndikuwonetsetsa kusalala ndi kukongola kwa pansi.

Kupaka kwamadzi: Kugwiritsa ntchito kwa MHEC mu zokutira zopanda madzi kumatha kupititsa patsogolo kupanga filimu komanso kusagwira madzi kwa zokutira ndikuletsa kulowa kwa chinyezi ndi kuwonongeka kwa zinthu.

Methylhydroxyethylcellulose amagwiritsidwa ntchito kwambiri pantchito zomanga chifukwa cha kusinthasintha kwake komanso zinthu zabwino kwambiri. Kuchokera pakukula, kusunga madzi, kugwirizanitsa kupanga mafilimu, MHEC imagwira ntchito yofunika kwambiri popititsa patsogolo ntchito yomanga ndi zotsatira zomaliza za zipangizo zomangira. Ndi kupita patsogolo kosalekeza kwaukadaulo komanso kuzama kwa kafukufuku wogwiritsa ntchito, chiyembekezo chogwiritsa ntchito MHEC pantchito yomanga chidzakhala chokulirapo.
