Ntchito ya p-hydroxypropyl starch ether mumatope

Wowuma ether ndi mawu wamba a gulu la zowuma zosinthidwa zomwe zili ndi zomangira za ether mu molekyulu, yomwe imadziwikanso kuti wowuma wa etherified, womwe umagwiritsidwa ntchito kwambiri pamankhwala, chakudya, nsalu, kupanga mapepala, mankhwala a tsiku ndi tsiku, mafuta amafuta ndi mafakitale ena.Lero tikufotokozera makamaka ntchito ya wowuma ether mumatope:

1) Thirani matope, onjezerani anti-sagging, anti-sagging ndi rheological properties za matope.

Mwachitsanzo, popanga zomatira matailosi, putty, ndi pulasitala matope, makamaka tsopano kuti kupopera mbewu mankhwalawa kumafuna madzi ochulukirapo, monga matope opangidwa ndi gypsum, ndikofunikira kwambiri (gypsum wopopera pamakina amafunikira madzi ambiri koma amayambitsa kutsika kwambiri. , Etere wowuma akhoza kupanga chosowa ichi).Ndiko kuti, mphamvu yakunja ikagwiritsidwa ntchito, kukhuthala kumachepa, kumapangitsa kuti magwiridwe antchito ndi pompopompo, ndipo mphamvu yakunja ikachotsedwa, kukhuthala kumawonjezeka, ndikuwongolera kukana kwamphamvu.Pakuchulukirachulukira kwa matailosi, kuwonjezera wowuma ether kumatha kupititsa patsogolo kukana kwa zomatira za matailosi.

2) Maola otsegulira owonjezera

Kwa zomatira za matailosi, zimatha kukwaniritsa zofunikira za zomatira zapadera (Kalasi E, 20min yowonjezera mpaka 30min kuti ifike ku 0.5MPa) yomwe imakulitsa nthawi yotsegulira.Wowuma ether amatha kupangitsa kuti pamwamba pa gypsum base ndi dongo la simenti likhale losalala, losavuta kugwiritsa ntchito, komanso limakongoletsa bwino.Ndilofunika kwambiri pakupaka matope ndi matope owonda okongoletsera monga putty.

1. Wowuma ether amatha kusintha bwino anti-sag ndi anti-slip properties of mortar

Ma cellulose ether nthawi zambiri amatha kupititsa patsogolo kukhuthala komanso kusunga madzi kwadongosolo koma sangathe kupititsa patsogolo anti-sagging ndi anti-slip properties.

2. Makulidwe ndi mamasukidwe akayendedwe

Nthawi zambiri, mamasukidwe a cellulose ether ndi pafupifupi makumi zikwi, pamene mamasukidwe akayendedwe a wowuma etha ndi mazana angapo zikwi zingapo, koma izi sizikutanthauza kuti thickening katundu wa wowuma etha matope si zabwino monga za cellulose ether, ndipo makulidwe amachitidwe awiriwa ndi osiyana.

3. Anti-slip performance

Poyerekeza ndi ma cellulose ethers, wowuma ether amatha kuwonjezera kwambiri zokolola zoyambirira za zomatira za matailosi, potero kuwongolera zinthu zawo zotsutsana ndi kuterera.

4. Air-entraining

Ma cellulose ether ali ndi mphamvu yolowera mpweya, pamene starch ether alibe katundu wolowetsa mpweya.
