Kugwiritsa ntchito kwa HPMC mu zipangizo zomangira

Hydroxypropyl methylcellulose (HPMC)ndi ether ya cellulose yosakhala ionic yopangidwa kuchokera ku cellulose yachilengedwe ya polymer kudzera mu njira zingapo zopangira mankhwala. Ndi ufa woyera wopanda fungo, wopanda kukoma komanso wopanda poizoni womwe umatupa m'madzi ozizira kukhala yankho loyera kapena lopanda utsi pang'ono la colloidal. Ili ndi mphamvu zokhuthala, zomangira, zobalalitsa, zosakaniza, zopanga filimu, zoyimitsa, zokometsera, zopaka gelling, zapamwamba, zosunga chinyezi ndi zoteteza za colloides. Hydroxypropyl methylcellulose, methylcellulose ingagwiritsidwe ntchito mu zipangizo zomangira, makampani opaka utoto, utomoni wopangidwa, makampani opanga zinthu zadothi, mankhwala, chakudya, nsalu, ulimi, mankhwala a tsiku ndi tsiku ndi mafakitale ena.

Kugwiritsa ntchito kwakukulu kwa hydroxypropyl methylcellulose HPMC mu zipangizo zomangira:

1 Grout yopaka pulasitala yopangidwa ndi simenti

①Kupangitsa kuti phala lopaka pulasitiki likhale lofanana, kupangitsa kuti phala lopaka pulasitiki likhale losavuta kupukutira, kungathandize kuti phalalo lisagwedezeke, kungathandize kuti madzi aziyenda bwino komanso kuti liziyenda bwino, komanso kungathandize kuti ntchito igwire bwino ntchito.

②Kusunga madzi ambiri, kumawonjezera nthawi yoyika matope, kumawonjezera magwiridwe antchito, komanso kumathandiza kuti matopewo akhale ndi madzi okwanira komanso olimba kuti apange mphamvu zambiri zamakanika.

③ Yang'anirani momwe mpweya umalowera kuti muchotse ming'alu pamwamba pa chophimbacho ndikupanga malo osalala bwino.

Ma plaster awiri opangidwa ndi gypsum ndi zinthu zopangidwa ndi gypsum

①Kupangitsa kuti phala lopaka pulasitiki likhale lofanana, kupangitsa kuti phala lopaka pulasitiki likhale losavuta kupukutira, kungathandize kuti phalalo lisagwedezeke, kungathandize kuti madzi aziyenda bwino komanso kuti liziyenda bwino, komanso kungathandize kuti ntchito igwire bwino ntchito.

②Kusunga madzi ambiri, kumawonjezera nthawi yoyika matope, kumawonjezera magwiridwe antchito, komanso kumathandiza kuti matopewo akhale ndi madzi okwanira komanso olimba kuti apange mphamvu zambiri zamakanika.

③ Onetsetsani kuti matopewo akufanana ndipo apange chophimba chabwino kwambiri pamwamba pake.

3 Simenti yopangira miyala

①Limbikitsani kumatirira pamwamba pa miyala, onjezerani kusunga madzi, ndikuwongolera mphamvu ya matope.

②Kukweza kukhuthala ndi kusinthasintha kwa zinthu, ndikuwonjezera kugwira ntchito bwino; matope omwe amakonzedwa bwino ndi cellulose ether ndi osavuta kupanga, amasunga nthawi yomanga ndikuchepetsa ndalama zomangira.

③Etha yosunga madzi ambiri yokwanira, yoyenera njerwa zomwe zimayamwa madzi ambiri.
Zodzaza mbale zinayi

①Kusunga madzi bwino kwambiri, kumawonjezera nthawi yotsegulira komanso kumawonjezera magwiridwe antchito. Mafuta ambiri, osavuta kusakaniza.

②Kulimbitsa kukana kufooka ndi kukana ming'alu, ndikukweza ubwino wa pamwamba pa chophimbacho.

③Konzani kuti pamwamba pa cholumikiziracho pakhale pomatirira bwino ndipo pakhale mawonekedwe osalala komanso osalala.

Zomatira za Matailosi 5

①Sakanizani zosakaniza mosavuta, palibe zotupa zomwe zidzapangike, liwiro la kugwiritsa ntchito lidzawonjezeka, magwiridwe antchito a zomangamanga adzakwera, nthawi yogwirira ntchito idzasungidwa, ndipo mtengo wogwirira ntchito udzachepetsedwa.

②Mwa kuwonjezera nthawi yotsegulira, kumawonjezera mphamvu ya matailosi ndipo kumapereka mphamvu yabwino kwambiri yomatira.

Zipangizo 6 zodzipangira pansi

① Amapereka kukhuthala ndipo angagwiritsidwe ntchito ngati chothandizira choletsa kukhazikika.

②Kupangitsa kuti madzi aziyenda bwino komanso kuti misewu isamayende bwino.

③ Yang'anirani kusunga madzi ndi kufupika kuti muchepetse ming'alu ndi kufupika kwa nthaka.

7 Utoto wopangidwa ndi madzi

①Pewani mvula yolimba ndikuwonjezera nthawi ya chidebe cha mankhwala. Kukhazikika kwachilengedwe komanso kugwirizana bwino ndi zinthu zina.

②Kuwonjezera kusinthasintha kwa madzi, kupereka kukana kwabwino kwa kupopera madzi, kukana kutsika ndi kusinthasintha, ndikuwonetsetsa kuti pamwamba pake pakhala bwino kwambiri.

Ufa wa mapepala ophimba mapepala 8

①Sungunulani mwachangu popanda kusonkhana, komwe kuli kosavuta kusakaniza.

②Kupereka mphamvu yolimba kwambiri.

9 Bolodi la simenti lopangidwa ndi extruded

①Ili ndi kulimba kwambiri komanso kukhuthala, ndipo imapangitsa kuti zinthu zotulutsidwa zigwire bwino ntchito.

②Kulimbitsa mphamvu yobiriwira, kulimbikitsa madzi ndi mphamvu yochiritsa, komanso kuonjezera zokolola.

Zinthu 10 za HPMC zopangira matope osakaniza kale

TheHPMCChogwiritsidwa ntchito makamaka pa matope osakaniza kale chili ndi madzi abwino kuposa zinthu wamba zomwe zili mu matope osakaniza kale, zomwe zimaonetsetsa kuti zinthu zopanda organic simenti zimakhala ndi madzi okwanira, komanso zimaletsa kwambiri kuchepa kwa mphamvu yomangira chifukwa cha kuumitsa kwambiri ndi kusweka komwe kumachitika chifukwa cha kuchepa kwa kuumitsa. HPMC ilinso ndi mphamvu yolumikizira mpweya. Zogulitsa za HPMC zomwe zimagwiritsidwa ntchito makamaka pa matope osakaniza kale zimakhala ndi mpweya wokwanira, wofanana komanso wocheperako, zomwe zimatha kulimbitsa mphamvu ndi kupaka pulasitala wa matope osakaniza kale. Chogulitsa cha HPMC chomwe chimagwiritsidwa ntchito makamaka pa matope osakaniza kale chili ndi mphamvu yochedwetsa, yomwe imatha kukulitsa nthawi yotsegulira matope osakaniza kale ndikuchepetsa zovuta zomangira. Hydroxypropyl methylcellulose (HPMC) ndi ether ya cellulose yosakhala ionic yopangidwa kuchokera ku cellulose yachilengedwe ya polymer kudzera mu njira zingapo zopangira mankhwala. Ndi ufa woyera wopanda fungo, wopanda kukoma komanso wopanda poizoni womwe umatupa m'madzi ozizira kukhala yankho lomveka bwino kapena lopanda utsi pang'ono. Ili ndi mphamvu zokhuthala, kumangirira, kufalitsa, kusakaniza, kupanga filimu, kuyimitsa, kusakaniza, kufalitsa gelling, mphamvu za pamwamba, kusunga chinyezi ndi ma colloid oteteza. Hydroxypropyl methylcellulose, methylcellulose ingagwiritsidwe ntchito mu zipangizo zomangira, makampani opaka utoto, utomoni wopangidwa, makampani opanga zinthu zadothi, mankhwala, chakudya, nsalu, ulimi, mankhwala a tsiku ndi tsiku ndi mafakitale ena.
