HPMC (hydroxypropyl methylcellulose) ndi zinthu zosiyanasiyana zama mankhwala zomwe zimagwiritsidwa ntchito kwambiri pomanga ndi m'mafakitale ena. Ndi ether yopanda ionic cellulose yopangidwa kuchokera ku cellulose yachilengedwe yosinthidwa ndi mankhwala. HPMC ali ndi ntchito zosiyanasiyana monga thickening, kasungidwe madzi, filimu mapangidwe, lubrication, ndi adhesion, kuwapatsa yotakata ntchito kuthekera makampani zomangamanga.
1. Kuchita kwakukulu kwa HPMC muzomangamanga
(1) Kunenepa
Pamene HPMC kusungunuka m'madzi, akhoza kwambiri kuonjezera mamasukidwe akayendedwe a madzi. Izi thickening zotsatira ndi zofunika kwambiri zomangira. Mwachitsanzo, mumatope a simenti, HPMC imatha kupititsa patsogolo kukhuthala kwa matope, kukonza zomangamanga, ndikupangitsa kuti ntchitoyo ikhale yabwino.
(2) Kusunga madzi
HPMC ili ndi zinthu zabwino kwambiri zosungira madzi, zomwe zimachepetsa kutuluka kwa madzi pakauma. Izi ndizofunikira makamaka pazinthu zopangidwa ndi simenti kuti matope kapena konkire zisaume kapena kutaya mphamvu chifukwa cha kutaya msanga kwa chinyezi musanakhazikike. Kuphatikiza apo, kusungirako madzi kumatha kukonza nthawi yotsegulira zomatira ndi ufa wa putty, kupatsa ogwira ntchito yomanga nthawi yochulukirapo kuti asinthe.
(3) Katundu wa anti-sag
Pomanga moyima (monga pulasitala pakhoma kapena kuyika matayala), HPMC imatha kuteteza zinthu kuti zisatsetserekere chifukwa cha mphamvu yokoka. Zimathandizira matope kapena zomatira kukhala zomatira bwino ndikuwonetsetsa kuti zimamangidwa bwino.
(4) Zinthu zabwino kwambiri zopangira mafilimu
HPMC imapanga filimu yofananira itatha kuyanika, chinthu chopanga filimu chomwe chili chofunikira kwambiri pa zokutira zopanda madzi komanso pansi pamadzi. Chophimba chopangidwa ndi filimu chimatha kupititsa patsogolo kukana kwa madzi ndi kukana kwa nyengo kwa zinthuzo.
(5) Mafuta ndi kugwirizana zotsatira
HPMC imatha kupititsa patsogolo mafuta azinthu zomangira, kuchepetsa mikangano pakumanga, ndikupangitsa kuti zinthuzo zifalikire bwino pamwamba pa gawo lapansi. Kuphatikiza apo, HPMC imatha kukulitsa zomangira zomangira ndikuwonjezera mphamvu zomangira pazomatira zina.
2. Kugwiritsa ntchito HPMC m'magawo apadera omanga
(1) Dongo lopangidwa ndi simenti
Popaka matope, matope omangira, ndi matope odzipangira okha, HPMC imatha kukonza kusungidwa kwamadzi ndi madzi amtondo, potero kumapangitsa kuti ntchito yomanga ikhale yabwino komanso mawonekedwe omaliza. Kuphatikiza apo, katundu wa anti-sag wa HPMC amawonetsetsa kuti matope sangatsike mosavuta akagwiritsidwa ntchito pamakoma oyimirira.
(2) Zomatira matailosi a ceramic
Zofunikira zazikulu zomatira matailosi ndi mphamvu yomangirira komanso kuphweka kwa zomangamanga. HPMC mu zomatira matailosi sangangowonjezera kumamatira kwa colloid, komanso kukulitsa nthawi yotsegulira, kulola ogwira ntchito yomanga kukhala ndi nthawi yayitali yosinthira, motero kupititsa patsogolo ntchito yomanga.
(3) Ufa wa putty
HPMC imapereka ufa wa putty kusungirako bwino kwa madzi ndi madzi. Pakumanga kwa putty, kusungirako madzi kumalepheretsa gawo loyambira kuti lisatenge madzi mwachangu, kuonetsetsa kuti putty imawuma mofanana, ndikuchepetsa chiopsezo chosweka ndi kugwa.
(4) Kupaka madzi
Mafilimu opanga mafilimu a HPMC ndi oyenera kwambiri zokutira madzi. Zitha kuthandizira zokutira kuti zikhale zosanjikiza komanso zofananira zosanjikiza madzi pamwamba pa gawo lapansi kuti zithandizire kuti nyumbayo ikhale yosalowa madzi.
(5) Zopangidwa ndi Gypsum
Mu gypsum-based screeding and pulasitala zipangizo, HPMC amapereka madzi osungira bwino, kuteteza gypsum kutaya mphamvu chifukwa cha kutaya kwambiri chinyezi. Pa nthawi yomweyo thickening zotsatira angathe kusintha omasuka ntchito.
3. Ubwino ndi malire a HPMC
Ubwino:
Kugwiritsa ntchito kwakukulu: Yoyenera magawo osiyanasiyana, monga simenti, gypsum, laimu, ndi zina.
Chitetezo cha chilengedwe: Monga chochokera ku cellulose, HPMC ndi yotetezeka, yopanda poizoni ndipo imakwaniritsa zofunikira zoteteza chilengedwe.
Kusinthasintha: Amapereka zinthu zosiyanasiyana monga kusunga madzi, kukhuthala, ndi kupanga mafilimu, ndipo amatha kusintha malinga ndi zosowa zosiyanasiyana za zomangamanga.
malire:
Mtengo: Mtengo wa HPMC ndi wokwera pang'ono poyerekeza ndi zida zachikhalidwe, zomwe zingapangitse mtengo wopangira zida zomangira.
Zolepheretsa Kukaniza kwa Alkaline: Kuchita kwa HPMC kumatha kuchepetsedwa m'malo ena amchere kwambiri, zomwe zimafunikira kuyesedwa ndi kusintha kwa chilengedwe.
4. Kuthekera kwa HPMC pakumanga kwamtsogolo
Pomwe kufunikira kwamakampani opanga zinthu zogwira ntchito kwambiri, zida zokomera chilengedwe zikukula, magawo ogwiritsira ntchito a HPMC akukulirakulira. Mwachitsanzo, m'nyumba zobiriwira ndi nyumba zopanda mphamvu zochepa, HPMC ikhoza kugwiritsidwa ntchito ngati chowonjezera chachikulu kuti apange zida zomangira zosagwiritsa ntchito mphamvu komanso zachilengedwe. Nthawi yomweyo, ndi kupita patsogolo kwaukadaulo, magwiridwe antchito ndi kukhazikika kwa HPMC zidzasinthidwanso.
Monga chowonjezera cha multifunctional,Mtengo wa HPMCali ndi gawo losasinthika pazantchito zomanga. Kuchokera kumatope a simenti kupita ku zomatira matailosi, kuchokera ku ufa wa putty kupita ku zokutira zosakhala ndi madzi, zitha kugwiritsidwa ntchito pafupifupi pafupifupi zida zonse zomangira. Ndi katundu wake wabwino kwambiri, HPMC imathandizira kupititsa patsogolo ntchito yomanga komanso kulimba kwa zida zomangira ndipo ndi gawo lofunikira pakukula kwamtsogolo kwamakampani omanga.
