(1) Chidule cha instant hydroxypropyl methylcellulose
Instant hydroxypropyl methylcellulose (HPMC) ndi ether yosakhala ionic cellulose yomwe imapezeka mwa kusintha kwa cellulose yachilengedwe ndipo imakhala ndi kusungunuka kwabwino komanso mawonekedwe a viscosity.Mapangidwe ake a maselo ali ndi magulu a hydroxyl, methoxy ndi hydroxypropoxy.Magulu ogwira ntchitowa amapereka mphamvu yapadera ya thupi ndi mankhwala, zomwe zimapangitsa kuti zikhale zofunikira muzogwiritsira ntchito zosiyanasiyana.
(2) Ntchito ya HPMC mu zomatira zomangamanga
Pantchito yomanga, HPMC ndi chowonjezera chofunikira ndipo chimagwiritsidwa ntchito kwambiri pazomatira zosiyanasiyana zomangira, monga zomatira matailosi, zomatira pakhoma, matope owuma, ndi zina zambiri. Ntchito zake zazikulu pakumanga zomatira ndizo:
1. Kunenepa kwambiri
HPMC akhoza kwambiri kuonjezera mamasukidwe akayendedwe ndi kugwirizana kwa zomangamanga zomatira.Kukhuthala kwake kumabwera chifukwa cha kutupa kwake m'madzi ndi mawonekedwe a intermolecular hydrogen bond network.Kukhuthala koyenera kumatha kupititsa patsogolo magwiridwe antchito a zida pakumanga ndikuletsa zomatira kuti zisagwere zikagwiritsidwa ntchito pamalo oyimirira, potero kuonetsetsa kuti zomangamanga zili bwino.
2. Mphamvu yosungira madzi
HPMC ili ndi malo abwino kwambiri osungira madzi, omwe amatha kuchepetsa kutaya kwa madzi panthawi yomanga.Kusunga madzi ndi khalidwe lofunika la zomatira zomangira.Makamaka muzinthu zopangira simenti ndi gypsum, mphamvu yosungira madzi ya HPMC imatha kukulitsa nthawi yotseguka ya zomatira, kupereka nthawi yayitali yosinthira ndi yomanga, kupewa kusweka koyambirira ndikuchepetsa mphamvu.
3. Kuwongolera magwiridwe antchito
HPMC imatha kupititsa patsogolo magwiridwe antchito a zomatira zomangira, kuphatikiza fluidity, kumanga ndi flattening.Mphamvu yake yopaka mafuta imapangitsa kuti zomatira zikhale zosavuta kugwiritsa ntchito ndi kukwapula panthawi yomanga, kumapangitsa kuti ntchito yomanga ikhale yabwino komanso yosalala ya malo omanga, ndikuwonetsetsa kuti ntchito yomaliza yomanga.
4. Kupititsa patsogolo mgwirizano
HPMC ikhoza kupititsa patsogolo kaphatikizidwe pakati pa zomatira ndi gawo lapansi ndikusintha mphamvu yomangirira ya zomatira popanga wosanjikiza yunifolomu komanso wolumikizana bwino.Izi ndizofunikira kwambiri pakukhazikika kwa nyumba zomangira monga makoma ndi pansi, ndipo zimatha kuletsa matailosi, matailosi oyang'ana, ndi zina kuti zisagwe.
5. Anti-slip performance
Muzogwiritsa ntchito monga zomatira matailosi, HPMC imatha kupititsa patsogolo luso loletsa kutsetsereka kwa zinthuzo.Izi zimathandiza kuti matailosi asasunthike pamalo omangidwa moyima, kuchepetsa kuchuluka kwa zosintha ndi kuchuluka kwa ntchito, motero kumapangitsa kuti zomangamanga zikhale bwino.
(3) Kugwiritsa ntchito kwapadera kwa HPMC pazomatira zosiyanasiyana zomangira
1. Zomatira matailosi
Mu zomatira matailosi, HPMC sikuti imangotenga gawo pakukulitsa ndi kusunga madzi, komanso imapangitsa kuti matailosi asamayende bwino, ndikuwonetsetsa kuti matailosi akhazikika pakumanga.Makhalidwe ake apadera a rheological amathandiza kuti zomatira zikhalebe ndi kukhuthala koyenera pansi pamikhalidwe yosiyanasiyana yomanga, zomwe zimapangitsa kuti zikhale zosavuta kusintha ndi kupanga.
2. Wall putty
HPMC makamaka imagwira ntchito posunga madzi ndi kukhuthala mu khoma la putty, kupangitsa putty kukhala yogwira ntchito komanso kukhala ndi malo osalala pambuyo poyanika.Kusungidwa kwake kwa madzi kumatha kuchepetsa kusweka ndi kutsika kwa putty wosanjikiza pakumanga, ndikuwongolera mtundu wa zokutira komaliza.
3. Dothi louma
Mumatope owuma, ntchito yayikulu ya HPMC ndikusunga chinyezi ndikuletsa kutaya madzi koyambirira, potero kumapangitsa kuti matopewo azigwira ntchito komanso kumamatira.Itha kusinthanso kusasinthika kwa matope kuti ikhale yoyenera pazomanga zosiyanasiyana, monga matope omanga, pulasitala matope, ndi zina zambiri.
4. Kumanga sealant
HPMC amagwiritsidwa ntchito makamaka pomanga zosindikizira kuti apititse patsogolo kusungunuka kwa madzi ndi kugwira ntchito kwa colloid, kuti athe kudzaza ziwalozo panthawi yogwiritsira ntchito ndikukhalabe bwino komanso kumamatira.Kusungidwa kwa madzi ake kungathenso kulepheretsa sealant kutaya madzi mofulumira komanso kupititsa patsogolo ntchito yomanga.
(4) Ubwino wa HPMC pomanga zomatira
Chitetezo cha chilengedwe: HPMC imachokera ku cellulose yachilengedwe, imakhala ndi mankhwala okhazikika, samatulutsa zinthu zovulaza panthawi yogwiritsira ntchito, ndipo ndi ochezeka ku chilengedwe ndi thupi la munthu.
Kukhazikika: HPMC ili ndi kukhazikika kwa mankhwala ndipo sichimakhudzidwa mosavuta ndi zinthu zachilengedwe monga kutentha ndi pH, ndipo imatha kusunga ntchito yake kwa nthawi yaitali.
Kugwirizana: HPMC imagwirizana ndi zida zosiyanasiyana zomangira ndipo imatha kuphatikizidwa bwino ndi zinthu monga simenti, gypsum, ndi matope kuti igwiritse ntchito makulidwe ake ndikusunga madzi.
(5) Zomwe zikuchitika m'tsogolomu
Ndi chitukuko chaukadaulo womanga, chiyembekezo chogwiritsa ntchito HPMC pakumanga zomatira ndi chachikulu.Mayendedwe otukuka amtsogolo ndi awa:
Kupititsa patsogolo ntchito: Sinthani kusinthasintha kwa HPMC kudzera mukusintha kwamankhwala kapena kuphatikiza ndi zowonjezera zina kuti zikwaniritse zosowa zamitundu yosiyanasiyana yomanga.
Zogulitsa zachilengedwe: Pangani zida za HPMC zosakonda zachilengedwe komanso zowonongeka kuti muchepetse kuwononga chilengedwe.
Zida zanzeru: Onani momwe HPMC imagwiritsidwira ntchito muzomangira zanzeru, monga zomatira zodzichiritsa nokha, zida zolimbana ndi kutentha, ndi zina zambiri, kuti mupititse patsogolo luso lazomangamanga.
Instant hydroxypropyl methylcellulose, monga chowonjezera chofunikira pomanga zomatira, imagwira ntchito yofunika kwambiri pakuwongolera kukhuthala, kusunga madzi, komanso kupanga zomatira.Kugwiritsa ntchito kwake pazomatira matailosi, putty pakhoma, matope owuma ndi madera ena kwathandizira kwambiri zomangamanga komanso magwiridwe antchito.M'tsogolomu, kudzera muukadaulo wopitilira muyeso komanso kupititsa patsogolo chidziwitso cha chilengedwe, kugwiritsa ntchito HPMC pomanga zomatira kudzabweretsa chitukuko chokulirapo.
