1. Simenti ya simenti: Imathandiza kuti mchenga wa simenti usamasweke bwino, imathandiza kuti madzi asasungunuke komanso kuti simenti isasweke, imathandiza kuti simenti isasweke, komanso imalimbitsa mphamvu ya simenti.
2. Simenti ya matailosi: imalimbitsa pulasitiki ndi kusunga madzi a matope oponderezedwa, imalimbitsa kumatirira kwa matailosi, komanso imaletsa kuyika choko.
3. Kupaka zinthu zotsutsa monga asbestos: monga chinthu choyimitsa, chinthu chowonjezera madzi, komanso kumawonjezera mphamvu yolumikizirana ndi substrate.
4. Kuthira kwa gypsum coagulation: kumathandizira kusunga madzi ndi kusinthasintha, komanso kumathandizira kumamatira ku substrate.
5. Simenti yolumikizirana: imawonjezeredwa ku simenti yolumikizirana kuti ipange bolodi la gypsum kuti madzi aziyenda bwino komanso kuti madzi azisungidwa bwino.
6. Latex putty: imawonjezera kusinthasintha kwa madzi ndi kusunga madzi kwa resin latex-based putty.
7. Stucco: Monga phala lolowa m'malo mwa zinthu zachilengedwe, lingathandize kusunga madzi ndikuwonjezera mphamvu yolumikizana ndi substrate.
8. Zophimba: Monga pulasitiki yopangira zophimba za latex, imatha kukonza magwiridwe antchito ndi kusinthasintha kwa zophimba ndi ufa wa putty.
9. Utoto wopopera: Uli ndi mphamvu yabwino yoletsa kumiza kwa simenti kapena zinthu zopopera za latex ndi zodzaza komanso kukonza kusinthasintha kwa madzi ndi kapangidwe ka kupopera.
10. Zinthu zina zochokera ku simenti ndi gypsum: zimagwiritsidwa ntchito ngati chomangira chopangira zinthu zamadzimadzi monga simenti-asbestos, kuti ziwongolere kusinthasintha kwa madzi ndikupeza zinthu zofanana zowumbidwa.
11. Khoma la ulusi: Chifukwa cha mphamvu yake yoletsa ma enzyme ndi mabakiteriya, imagwira ntchito ngati chomangira makoma a mchenga.
12. Zina: Zingagwiritsidwe ntchito ngati chosungira thovu pa matope owonda a mchenga wa dongo ndi makina ogwiritsira ntchito matope a hydraulic.

Hydroxyethyl Methyl cellulose
1. Mu mankhwala, imagwiritsidwa ntchito ngati chinthu choteteza mafupa a gel, porogen, ndi chophimba pokonzekera mankhwala otulutsa mpweya nthawi zonse. Ingagwiritsidwenso ntchito ngati chokhuthala, choyimitsa, chobalalitsira, chomangirira, chopanga filimu, komanso chosunga madzi pokonzekera.
2. Kukonza chakudya kungagwiritsidwenso ntchito ngati, zomatira, emulsifying, film-forming, thickening, suspending, dispersing, anthink-retaining agent, etc.
3. Mu makampani opanga mankhwala tsiku ndi tsiku, imagwiritsidwa ntchito ngati chowonjezera mu mankhwala otsukira mano, zodzoladzola, sopo, ndi zina zotero.
4. Amagwiritsidwa ntchito ngati chothandizira kupanga simenti, gypsum ndi laimu, chothandizira kusunga madzi, komanso chosakaniza chabwino kwambiri cha zipangizo zomangira ufa.
5. Hydroxymethylcellulose imagwiritsidwa ntchito kwambiri ngati chowonjezera mu mankhwala, kuphatikizapo mapiritsi omwa, zotsukira ndi zokonzekera zapakhungu. Kapangidwe kake ndi kofanana ndi methyl cellulose, koma chifukwa cha kukhalapo kwa hydroxyethyl cellulose, ndikosavuta kusungunuka m'madzi, yankho limagwirizana bwino ndi mchere, ndipo limakhala ndi kutentha kwakukulu kwa magazi.

Carboxymethyl cellulose
1. Amagwiritsidwa ntchito pobowola mafuta ndi gasi lachilengedwe, kukumba zitsime ndi ntchito zina
① Matope okhala ndi CMC angapangitse khoma la chitsime kukhala lopyapyala komanso lolimba lokhala ndi madzi ochepa, zomwe zimachepetsa kutaya madzi.
② Pambuyo powonjezera CMC ku matope, chobowoleracho chingakhale ndi mphamvu yochepa yoyambira yochekera, kotero kuti matopewo azitha kutulutsa mosavuta mpweya womwe wakulungidwamo, ndipo nthawi yomweyo, zinyalala zitha kutayidwa mwachangu m'dzenje la matope.
③ Matope obowola, monga ma suspension ndi ma dispersions ena, amakhala ndi nthawi yokhazikika. Kuyika CMC kungathandize kuti ikhale yokhazikika ndikuwonjezera nthawi yokhazikika.
④ Matope okhala ndi CMC sakhudzidwa kawirikawiri ndi nkhungu, choncho ayenera kukhala ndi pH yokwera, ndipo sikofunikira kugwiritsa ntchito zosungira.
⑤ Ili ndi CMC ngati mankhwala ochizira pobowola madzi otsukira matope, omwe amatha kupirira kuipitsidwa kwa mchere wosiyanasiyana wosungunuka.
⑥ Matope okhala ndi CMC ali ndi kukhazikika bwino ndipo amatha kuchepetsa kutayika kwa madzi ngakhale kutentha kuli pamwamba pa 150°C.
CMC yokhala ndi kukhuthala kwakukulu komanso kusinthasintha kwakukulu ndi yoyenera matope okhala ndi kukhuthala kochepa, ndipo CMC yokhala ndi kukhuthala kochepa komanso kusinthasintha kwakukulu ndi yoyenera matope okhala ndi kukhuthala kwakukulu. Kusankha CMC kuyenera kutsimikiziridwa malinga ndi mikhalidwe yosiyanasiyana monga mtundu wa matope, dera, ndi kuya kwa chitsime.
2. Amagwiritsidwa ntchito m'mafakitale opanga nsalu, kusindikiza ndi kuyika utoto. Mu makampani opanga nsalu, CMC imagwiritsidwa ntchito ngati chothandizira kukula kwa ulusi wopepuka wa thonje, ubweya wa silika, ulusi wa mankhwala, zosakaniza ndi zina zolimba;
3. CMC yogwiritsidwa ntchito mumakampani opanga mapepala ingagwiritsidwe ntchito ngati choyeretsera mapepala ndi choyeretsera kukula kwa mapepala mumakampani opanga mapepala. Kuwonjezera 0.1% mpaka 0.3% ya CMC mu zamkati kungapangitse kuti pepala likhale lolimba ndi 40% mpaka 50%, kuwonjezera kukana kwa ming'alu ndi 50%, ndikuwonjezera mphamvu yokanda ndi nthawi 4 mpaka 5.
4. CMC ingagwiritsidwe ntchito ngati chokometsera dothi ikawonjezedwa ku sopo wopangidwa; mankhwala a tsiku ndi tsiku monga makampani opanga mano. CMC glycerol aqueous solution imagwiritsidwa ntchito ngati maziko a mano otsukira mano; makampani opanga mankhwala amagwiritsidwa ntchito ngati chokhuthala ndi chosakaniza; CMC aqueous solution imagwiritsidwa ntchito ngati choyandama pambuyo pokhuthala. Kukumba ndi zina zotero.
5. Itha kugwiritsidwa ntchito ngati zomatira, pulasitiki, choyimitsa glaze, chokonzera utoto, ndi zina zotero mumakampani opanga zinthu zadothi.
6. Amagwiritsidwa ntchito pomanga kuti awonjezere kusunga madzi ndi mphamvu
7. Amagwiritsidwa ntchito mumakampani opanga chakudya. Makampani opanga chakudya amagwiritsa ntchitoCMC yokhala ndi mlingo waukulu wolowa m'malo ngati chokhuthala cha ayisikilimu, chakudya cham'zitini, Zakudya zam'madzi zachangu, ndi chokhazikika cha thovu cha mowa. Chokhuthala, chomangirira. Makampani opanga mankhwala amasankha CMC yokhala ndi kukhuthala koyenera ngati chomangirira, chomangirira mapiritsi, ndi chomangira chomangirira, ndi zina zotero.

Methyl cellulose
Amagwiritsidwa ntchito ngati chokhuthala cha zomatira zosungunuka m'madzi, monga neoprene latex.
Ingagwiritsidwenso ntchito ngati chosungunula, chosakaniza ndi chokhazikika cha vinyl chloride ndi styrene suspension polymerization. MC yokhala ndi DS=2.4~2.7 imasungunuka mu polar organic solvent, zomwe zimatha kuletsa kusinthasintha kwa solvent (dichloromethane ethanol mix).
