Ma cellulose ethers, monga methyl cellulose (MC) ndi hydroxypropyl methyl cellulose (HPMC), amagwiritsidwa ntchito kwambiri pazinthu zopangidwa ndi simenti chifukwa cha kusungirako kwawo bwino madzi, kumagwira ntchito, komanso kumamatira. Komabe, magwiridwe antchito a cellulose ethers muzinthu za simenti amatha kukhudzidwa ndi zinthu zosiyanasiyana, kuphatikiza mtundu ndi mlingo wa cellulose ether, mtundu ndi mlingo wa simenti, machiritso, komanso momwe chilengedwe chimakhalira. Chifukwa chake, ndikofunikira kuyang'anira bwino magwiridwe antchito a cellulose ethers muzinthu za simenti kuti zitsimikizire kukhazikika komanso magwiridwe antchito.

1. Kusankha Mtundu wa Etere wa Cellulose ndi Mlingo

Kusankhidwa kwa mtundu wa cellulose ether ndi mlingo ndikofunikira pakuwongolera magwiridwe antchito a cellulose ether muzinthu za simenti. Ma ether osiyana a cellulose ali ndi katundu wosiyana, ndipo kusankha kwa mtundu woyenera wa cellulose ether kumadalira pa ntchito yeniyeni ndi zofunikira zogwirira ntchito. Mwachitsanzo, HPMC imagwiritsidwa ntchito kwambiri pomatira matailosi chifukwa chosunga bwino madzi komanso kumamatira, pomwe MC imagwiritsidwa ntchito kwambiri pomasulira ndi matope chifukwa chogwira ntchito bwino komanso kusunga madzi.

Mlingo wa cellulose ether umathandizanso kwambiri pakuwongolera magwiridwe antchito ake muzinthu za simenti. Mlingo woyenera wa cellulose ether umadalira zinthu zosiyanasiyana, kuphatikiza mtundu ndi mlingo wa simenti, momwe angagwiritsire ntchito komanso kusunga madzi, komanso chilengedwe. Nthawi zambiri, mlingo wa cellulose ether umachokera ku 0.1% mpaka 2% pa kulemera kwa simenti, malingana ndi ntchito yeniyeni ndi zofunikira zogwirira ntchito.

2. Kugwirizana ndi Cement

Kugwirizana kwa cellulose ether ndi simenti ndikofunikira pakuwongolera magwiridwe antchito ake muzinthu za simenti. Kuphatikizika kwa cellulose ether ku simenti kungakhudze nthawi yoyika, mphamvu, ndi magwiridwe antchito a simenti, kutengera mtundu ndi mlingo wa cellulose ether ndi mtundu wa simenti. Chifukwa chake, ndikofunikira kuwonetsetsa kuti cellulose ether imagwirizana ndi simenti kuti zitsimikizire kukhazikika komanso magwiridwe antchito.

Kugwirizana kwa cellulose ether ndi simenti kungayesedwe poyesa kuyanjana, monga mayeso a Vicat, kuyesa koyambirira ndi komaliza kwa nthawi, komanso kuyesa kwamphamvu kwamphamvu. Zotsatira za mayesowa zitha kupereka chidziwitso chofunikira pa magwiridwe antchito a cellulose ether muzinthu za simenti ndipo angagwiritsidwe ntchito kukhathamiritsa mtundu ndi mlingo wa cellulose ether.

3. Kuchiritsa Zinthu

Kuchiritsa kwa zinthu za simenti kumatha kukhudza kwambiri magwiridwe antchito a cellulose ethers. Machiritso, kuphatikizapo kutentha, chinyezi, ndi nthawi yochiritsa, zingakhudze kusungunuka kwa simenti ndi kachitidwe ka cellulose ethers. Machiritso abwino kwambiri amadalira kagwiritsidwe ntchito kake komanso zofunikira pakuchita.

Mwachitsanzo, mu zomatira matailosi, machiritso abwino kwambiri amakhala pa kutentha kwapakati ndi chinyezi chapakati komanso nthawi yochiritsa ya maola 24 mpaka 48. M'matembenuzidwe ndi matope, machiritso oyenera amatha kusiyanasiyana kutengera momwe akugwiritsidwira ntchito, koma nthawi zambiri amaphatikiza kutentha kwambiri komanso nthawi yayitali yochiritsa.

4. Mikhalidwe Yachilengedwe

Mikhalidwe ya chilengedwe, monga kutentha, chinyezi, ndi kukhudzana ndi mankhwala kapena zowononga, zingakhudzenso kagwiritsidwe ntchito ka cellulose ethers muzinthu za simenti. Mwachitsanzo, kukhudzana ndi kutentha kwambiri kapena chinyezi chochepa kungakhudze momwe madzi amasungiramo ma cellulose ethers, zomwe zimapangitsa kuchepetsa kugwira ntchito ndi kumamatira. Kuwonetsedwa ndi mankhwala kapena zowononga zimatha kusokonezanso magwiridwe antchito a cellulose ethers, zomwe zimapangitsa kuchepa mphamvu kapena kulimba.

Chifukwa chake, ndikofunikira kuganizira momwe chilengedwe chimakhalira pakugwiritsa ntchito komanso kugwiritsa ntchito ma cellulose ethers muzinthu za simenti. Kusungidwa koyenera ndi kasamalidwe ka cellulose ethers kungathandizenso kusunga magwiridwe antchito awo ndikuwonetsetsa kuti zikhala bwino.

Pomaliza, kuwongolera kogwira mtima kwa ma cellulose ethers muzinthu za simenti kumafuna kuganizira mozama zinthu zosiyanasiyana, kuphatikiza mtundu ndi mlingo wa cellulose ether, kugwirizana ndi simenti, machiritso, komanso momwe chilengedwe chimakhalira. Mwa kukhathamiritsa zinthu izi, ndizotheka kukwaniritsa kusasinthika kwa ma cellulose ethers muzinthu za simenti, zomwe zimapangitsa kuti pakhale kugwirira ntchito bwino, kusunga madzi, komanso kumamatira.
