High viscosity dry mortar additive hydroxypropyl methylcellulose (HPMC)

Hydroxypropyl Methylcellulose (HPMC) ndi polymer cellulose ether yofunika kwambiri, yomwe imagwiritsidwa ntchito kwambiri pomanga, mankhwala, chakudya, zodzoladzola ndi zina. Mu matope owuma, HPMC ndi chowonjezera chofunikira, chomwe chimagwiritsidwa ntchito kwambiri popititsa patsogolo kaphatikizidwe kake, kusunga madzi, ntchito yomanga ndi zina, makamaka pamagwiritsidwe omwe ali ndi zofunikira zazikulu za kukhuthala.

Makhalidwe oyambira a HPMC
HPMC imasinthidwa ndi mankhwala kuchokera ku cellulose yachilengedwe ya polima. Imakhala ndi kusungunuka kwamadzi bwino, kusagwirizana komanso kusakhazikika kwachilengedwe, zomwe zimapangitsa kuti ikhale yowonjezera zachilengedwe komanso yotetezeka. HPMC ali kwambiri thickening, filimu kupanga, posungira madzi, suspending ndi emulsifying katundu, amene ambiri ntchito youma matope.

Udindo wa HPMC mumatope owuma
Kusungirako madzi: HPMC ikhoza kupititsa patsogolo kasungidwe ka madzi mumatope owuma ndikuchepetsa kutaya madzi pakumanga. Izi ndizofunikira kuti tipewe kusweka ndi kutaya mphamvu chifukwa cha matope kutaya madzi mwachangu kwambiri. Makamaka nyengo yotentha ndi youma, kusunga madzi ndikofunikira kwambiri.

Kukhuthala kwamphamvu: HPMC imatha kukulitsa kukhuthala kwa matope owuma, ndikupangitsa kuti ikhale yamadzimadzi komanso yogwira ntchito pomanga. High mamasukidwe akayendedwe HPMC akhoza kuonjezera sagging kukana mu matope youma, kupangitsa kukhala oyenera kumanga pa ofukula kapena inaimitsidwa pamalo.

Kupititsa patsogolo ntchito yomanga: HPMC imatha kukonza magwiridwe antchito a matope owuma, kupangitsa kuti ikhale yosavuta kufalikira komanso mulingo. Katunduyu ndi wofunikira kwambiri pakumanga zopyapyala, monga matope opaka pulasitala omwe amagwiritsidwa ntchito pomanga matayala ndi kukongoletsa mkati ndi kunja kwa khoma.

Mphamvu yomangirira: HPMC imatha kupititsa patsogolo mphamvu yomangira yamatope owuma, makamaka kupereka magwiridwe antchito abwinoko pakati pa zinthu zoyambira ndi zapamtunda. Izi ndizofunikira kuti zitsimikizire kuti ntchitoyo ndi yabwino komanso kukulitsa moyo wa nyumbayo.

Momwe mungagwiritsire ntchito HPMC ndi zodzitetezera
Powonjezera HPMC ku matope owuma, nthawi zambiri amasakanikirana ndi zipangizo zina monga ufa wouma. Kuchulukitsa kwa HPMC nthawi zambiri kumakhala pakati pa 0.1% ndi 0.5%, zomwe zimasinthidwa malinga ndi zofunikira zosiyanasiyana zogwiritsira ntchito ndi mitundu yazinthu. Mukamagwiritsa ntchito, chidwi chiyenera kulipidwa pakuwonongeka kwake kuti tipewe kuphatikizika. Nthawi zambiri amalangizidwa kuti posakaniza matope owuma, HPMC iyenera kusakanizidwa bwino ndi ufa wina, ndiyeno madzi ayenera kuwonjezeredwa kuti agwedezeke kuti awonetsetse kuti asungunuka ndikubalalika.

Monga chowonjezera chofunikira mumatope owuma kwambiri, hydroxypropyl methylcellulose imakhala pamalo ofunikira pakumanga kwamakono chifukwa chakuchita bwino. Pokonza kusungirako madzi, kukhutitsidwa, ntchito yomanga komanso mphamvu yomangirira yamatope owuma, HPMC imapereka yankho lothandiza pakuwongolera magwiridwe antchito a zida zomangira. Nthawi yomweyo, monga zinthu zosamalira zachilengedwe, HPMC ili ndi chiyembekezo chogwiritsa ntchito pazinthu zomangira.
