dziwitsani:
Methylhydroxyethylcellulose (MHEC) ndi ether yosunthika ya cellulose yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa chosunga bwino madzi komanso zomatira.MHEC imachokera ku cellulose yachilengedwe ndipo yapeza ntchito pomanga, mankhwala, chakudya ndi zodzoladzola.
Mapangidwe a Chemical ndi katundu:
MHEC ndi methyl-substituted hydroxyethylcellulose yochokera ndi mawonekedwe apadera a maselo.Msana wa cellulose umapereka kusinthika kwachilengedwe komanso kuyanjana kwachilengedwe, ndikupangitsa MHEC kukhala chisankho choyamba pamapulogalamu ambiri.Magulu a Hydroxyethyl ndi methyl amathandizira kusungunuka kwake ndikusintha mawonekedwe ake akuthupi ndi mankhwala, ndikuwapatsa ntchito zosiyanasiyana.
Njira yosungira madzi:
Chimodzi mwazinthu zazikulu za MHEC ndikusunga bwino madzi.Muzomangamanga monga matope ndi zinthu zopangidwa ndi simenti, MHEC imakhala ngati wothandizira madzi, kuteteza kutaya madzi mofulumira panthawi yochiritsa.Izi ndizofunikira kuti mukhalebe ndi kuthekera koyenera, kuwongolera kumamatira komanso kupititsa patsogolo magwiridwe antchito azinthu zonse.
MHEC imakwaniritsa kusunga madzi kudzera munjira zingapo:
Hydrophilicity: Chikhalidwe cha hydrophilic cha MHEC chimathandiza kuti itenge ndi kusunga mamolekyu amadzi.Msana wa cellulose, limodzi ndi magulu a hydroxyethyl ndi methyl, umapanga mawonekedwe omwe amatha kusunga madzi mkati mwa matrix ake.
Kapangidwe ka filimu: MHEC imatha kupanga filimu yopyapyala, yosinthika ikamwazikana m'madzi.Firimuyi imakhala ngati chotchinga, kuchepetsa kutuluka kwa madzi ndikupereka chitetezo chotetezera chinyezi mkati mwazinthu.
Kukula kwake: Popeza MHEC imatupa m'madzi, imawonetsa kukhuthala.Kukhuthala kowonjezereka kumeneku kumathandizira kuti madzi asungidwe bwino, kulepheretsa madzi kupatukana ndi zinthuzo komanso kukhala ndi chisakanizo chofanana.
Mapulogalamu omanga:
Makampani omanga amadalira kwambiri MHEC chifukwa cha malo ake osungira madzi.MHEC imapindula ndi matope, grout ndi zida zina za simenti popititsa patsogolo ntchito, kuchepetsa kusweka ndi kukonza kumamatira.Kuonjezera apo, MHEC imathandizira kupopera ndi kupopera mankhwala a zipangizo zomangira, zomwe zimapangitsa kuti zikhale zofunikira kwambiri pa zomangamanga zamakono.
Zomatira:
Kuphatikiza pa kusungirako madzi, MHEC imagwira ntchito yofunika kwambiri pakuwongolera kumamatira m'njira zosiyanasiyana.Zomatira zake ndizofunika kwambiri m'mafakitale otsatirawa:
Zomatira za matailosi: MHEC imagwiritsidwa ntchito nthawi zambiri pazomatira matayala kuti alimbikitse mgwirizano pakati pa matailosi ndi gawo lapansi.Zimapanga mafilimu osinthika ndikuwongolera magwiridwe antchito, kuonetsetsa mgwirizano wamphamvu komanso wokhalitsa.
Kuyika Pazithunzi: Popanga zoyika pazithunzi, MHEC imathandizira kumangiriza khoma.Zimalepheretsa phala kuti lisaume msanga ndipo zimalimbikitsa mgwirizano wamphamvu komanso wokhalitsa.
Zophatikiza Zophatikizana: MHEC imagwiritsidwa ntchito pophatikizana chifukwa chomangirira komanso kukhuthala.Zimathandizira kukwaniritsa zosalala komanso zomatira pamapulogalamu a drywall.
Pomaliza:
Methylhydroxyethylcellulose (MHEC) ndi etha ya cellulose yokhala ndi mawonekedwe abwino kwambiri osungira madzi komanso zomatira.Kapangidwe kake kapadera ka maselo, hydrophilicity, luso lopanga filimu komanso kukhuthala kumapangitsa kuti azigwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.Kuchokera ku zida zomangira kupita ku mankhwala ndi zodzoladzola, MHEC imagwira ntchito yofunika kwambiri pakuwongolera magwiridwe antchito ndikuwonetsetsa kuti zimagwira ntchito bwino.Pamene mafakitale akupitirizabe kufunafuna njira zothetsera chilengedwe komanso zothandiza, MHEC ikupitirizabe kukhala njira yamtengo wapatali komanso yosasunthika pazochitika zosiyanasiyana.
