Hydroxypropyl methylcellulose (HPMC)ndizomwe zimagwiritsidwa ntchito popanga cellulose zosungunuka m'madzi, zomwe zimagwiritsidwa ntchito kwambiri pomanga, mankhwala, chakudya ndi mafakitale a tsiku ndi tsiku. Muzomangamanga, makamaka zomatira matailosi, ma putties a khoma, matope owuma, ndi zina zotero, HPMC, monga chowonjezera chachikulu, sichimangowonjezera ntchito yomanga, komanso imakhala ndi zotsatira zofunikira pa mgwirizano.
1. Basic katundu wa HPMC
AnxinCel®HPMC ndi chochokera ku cellulose chokhala ndi madzi abwino kusungunuka, kumamatira ndi kukhuthala. Amapanga colloid m'madzi kudzera m'magulu a hydroxypropyl ndi methyl mumapangidwe ake a maselo, omwe amatha kusintha bwino kumamatira, rheology ndi kusunga madzi kwa zinthuzo. Pomanga zomatira, kuwonjezera kwa HPMC kumatha kupititsa patsogolo mphamvu zomangirira, kutalikitsa nthawi yotseguka, ndikuwongolera kufalikira ndi kukana madzi. Choncho, kuchuluka kwa HPMC kumagwirizana mwachindunji ndi machitidwe a zinthuzi, zomwe zimakhudzanso kugwirizanitsa.
2. Mmene HPMC mlingo pa kugwirizana mphamvu
Mphamvu zomangirira ndi chizindikiro chofunikira chowunika momwe zomatira zimagwirira ntchito. Kuchuluka kwa HPMC kuwonjezeredwa pazomatira kumatha kukhudza kwambiri mphamvu yomangirira. Kumbali imodzi, kuchuluka koyenera kwa HPMC kumatha kupititsa patsogolo kulumikizana ndi kulimba kwa zida zopangira simenti. Izi ndichifukwa choti HPMC imapangitsa kuti madzi asungidwe mumatope, kulola simenti kuti igwirizane bwino ndi mankhwala ndi gawo lapansi panthawi yowumitsa, potero kumapangitsa kuti kumangiridwe komaliza. Kumbali ina, pamene kuchuluka kwa HPMC kuli kochepa kwambiri, kusungirako madzi sikukwanira, zomwe zingayambitse simenti kutaya madzi msanga, zomwe zimakhudza ndondomeko yowumitsa ndikuyambitsa mphamvu zomangira zosakhazikika; pamene kuchuluka kwake kuli kwakukulu, kungayambitse zomatira kukhala zowoneka bwino kwambiri, zomwe zimakhudza ntchito yomanga komanso kuchititsa kuchepa kwa mphamvu.
Kafukufuku wasonyeza kuti kuchuluka koyenera kwa HPMC nthawi zambiri kumakhala pakati pa 0.5% ndi 2%, zomwe zimatha kupititsa patsogolo mphamvu zomangirira mkati mwamtunduwu ndikuwonetsetsa kuti zinthu zina monga fluidity ndi magwiridwe antchito. Komabe, ndalama zenizenizo ziyenera kusinthidwa molingana ndi mtundu wa gawo lapansi komanso malo ogwiritsira ntchito.
3. Zotsatira za mlingo wa HPMC pa ntchito yomanga
Ntchito yomanga ndi imodzi mwazizindikiro zofunika pakuwunika zomatira, makamaka kuphatikiza madzimadzi, kumasuka kwa zomangamanga komanso nthawi yosinthika yogwirira ntchito. Kuchuluka kwa HPMC kumakhudza kwambiri zinthu izi. Pamene kuchuluka kwa HPMC kumawonjezeka, kukhuthala kwa zomatira kumawonjezekanso, kuwonetsa kumamatira kwamphamvu komanso nthawi yayitali yotseguka. Ngakhale kuti nthawi yayitali yotseguka nthawi zina imatha kusintha kusinthika kwa zomangamanga, kungayambitsenso kuti malo omangawo abwerere mmbuyo ndikusokoneza mgwirizano.
Pamitundu yosiyanasiyana ya magawo, monga matailosi, miyala, makoma, ndi zina zotero, kuchuluka kwa AnxinCel®HPMC kuyenera kukonzedwa. Mwachitsanzo, pazochitika zomwe nthawi yayitali yogwira ntchito ndi kusintha ikufunika, kuonjezera kuchuluka kwa HPMC moyenera kungathe kuwonjezera nthawi yotseguka ndikupewa kuyanika mofulumira, zomwe zimapangitsa kuti pakhale mgwirizano wofooka. Komabe, ngati nthawi yotseguka ndi yayitali kwambiri, ikhoza kuyambitsa kutsetsereka kosafunikira pakumanga ndikusokoneza kulondola kwa zomangamanga.
4. Zotsatira za mlingo wa HPMC pa kukana madzi ndi kukana kwa nyengo
HPMC osati kusintha mphamvu zomangira ndi ntchito yomanga, komanso kusintha kukana madzi ndi kukana nyengo ya zomatira. HPMC imathandizira kusungirako madzi kwa simenti, kotero kuti zomatira za simenti sizitaya madzi mwachangu panthawi yowumitsa, potero zimakulitsa kukana kwake kwamadzi komanso kukana kwanyengo. Mlingo wa HPMC ukayenera, kukana madzi ndi moyo wautumiki wa zinthuzo zitha kusintha kwambiri, makamaka m'makoma akunja ndi malo achinyezi, komwe kukana kwamadzimadzi ndikofunikira.
Komabe, HPMC yochulukirachulukira imatha kukulitsa zomatira, kusokoneza kukhazikika kwazinthu zopangira simenti, ndikuchepetsa kukana kwake kwamadzi. Chifukwa chake, kukhathamiritsa kwa mlingo wa HPMC kuti muchepetse kutsekemera kwa simenti ndi madzi kukana ndi chinsinsi chowonetsetsa kuti mgwirizano ukuyenda.
5. Zotsatira za mlingo wa HPMC pazinthu zina zakuthupi
Kuphatikiza pa mphamvu yomangirira, ntchito yomanga, kukana madzi, ndi zina zambiri, mulingo wa HPMC udzakhudzanso zinthu zina zomatira. Mwachitsanzo, pakuwonjezeka kwa mlingo wa HPMC, kukhazikika kwa zomatira kutha kuwongolera chifukwa HPMC imatha kuletsa sedimentation ndi stratification mu zomatira ndikusunga mawonekedwe ofanana. Komanso mlingo waMtengo wa HPMCzimagwirizananso kwambiri ndi zinthu monga mtundu, anti-slip properties, ndi kuchiritsa nthawi ya zomatira. Mlingo wosiyanasiyana wa HPMC utha kuchita bwino kwambiri pazofunikira zosiyanasiyana zomanga.
Monga chowonjezera chofunikira chomangira zomatira, AnxinCel®HPMC imakhala ndi mphamvu yolumikizirana. Mlingo wake uyenera kukonzedwa molingana ndi zofunikira zomanga, mawonekedwe a gawo lapansi ndi momwe chilengedwe chikuyendera. Kuchuluka koyenera kwa HPMC kumatha kupititsa patsogolo mphamvu zomangira, ntchito yomanga, kukana madzi komanso kukana nyengo, ndikusunga bata labwino. Komabe, HPMC yochulukira kapena yosakwanira imatha kupangitsa kuti zinthu zomatira zikhale zosakhazikika komanso kukhudza momwe zimakhalira. Chifukwa chake, pazogwiritsa ntchito, ndikofunikira kudziwa mulingo woyenera wa HPMC kudzera pakuyesa ndikusintha kuti mukwaniritse mgwirizano wabwino.
