Kodi ndi zinthu ziti zomwe zimakhudza kusunga madzi kwa ether ya cellulose?

Ma ether a cellulose, monga methyl cellulose (MC) ndi hydroxyethyl cellulose (HEC), amagwiritsidwa ntchito kwambiri ngati zinthu zosungira madzi mu zipangizo zomangira monga mortars zopangidwa ndi simenti ndi gypsum-based plasters. Kusunga madzi kwa ma ether a cellulose kumatha kukhudzidwa ndi zinthu zosiyanasiyana:

1. Kapangidwe ka Mankhwala: Kapangidwe ka mankhwala a ma cellulose ethers kamakhudza momwe amasungira madzi. Mwachitsanzo, hydroxyethyl cellulose (HEC) nthawi zambiri imakhala ndi madzi ambiri poyerekeza ndi methyl cellulose (MC) chifukwa cha kukhalapo kwa magulu a hydroxyethyl, omwe amawonjezera mphamvu yolumikizira madzi.
2. Kulemera kwa Mamolekyulu: Ma ether okhala ndi kulemera kwakukulu kwa mamolekyulu nthawi zambiri amakhala ndi mphamvu zabwino zosungira madzi chifukwa amapanga maukonde akuluakulu olumikizirana ndi mamolekyulu amadzi. Chifukwa chake, ma ether okhala ndi kulemera kwakukulu kwa mamolekyulu nthawi zambiri amasunga madzi bwino kuposa omwe ali ndi kulemera kochepa kwa mamolekyulu.
3. Mlingo: Kuchuluka kwa ether ya cellulose yomwe yawonjezeredwa ku matope kapena chisakanizo cha plaster kumakhudza mwachindunji kusunga madzi. Kuchulukitsa mlingo wa ether ya cellulose nthawi zambiri kumawonjezera kusunga madzi, mpaka kufika poti kuwonjezera kwina sikungawongolere kwambiri kusunga madzi ndipo kungawononge zinthu zina zomwe zili mkati mwake.
4. Kukula ndi Kugawa kwa Tinthu: Kukula kwa tinthu ndi kugawa kwa ma ether a cellulose kumatha kukhudza kufalikira kwawo komanso kugwira ntchito bwino posunga madzi. Ma ether a cellulose ophwanyidwa bwino okhala ndi kugawa kwa tinthu tofanana nthawi zambiri amafalikira mofanana mu chisakanizocho, zomwe zimapangitsa kuti madzi azisungidwa bwino.
5. Kutentha ndi Chinyezi: Mikhalidwe yachilengedwe, monga kutentha ndi chinyezi, ingakhudze kuchuluka kwa madzi ndi kusunga madzi kwa ma cellulose ethers. Kutentha kwambiri kungafulumizitse njira yopezera madzi, zomwe zimapangitsa kuti madzi azitha kuyamwa mwachangu komanso kuchepetsa kusunga madzi. Mosiyana ndi zimenezi, kuchepa kwa chinyezi kungayambitse kusungunuka kwa madzi ndikuchepetsa kusunga madzi.
6. Mtundu wa Simenti ndi Zowonjezera: Mtundu wa simenti ndi zowonjezera zina zomwe zimapezeka mu matope kapena chisakanizo cha plaster zimatha kuyanjana ndi ma ether a cellulose ndikukhudza momwe amasungira madzi. Mitundu ina ya simenti kapena zowonjezera zimatha kuwonjezera kapena kuletsa kusunga madzi kutengera momwe zimagwirizanirana ndi mankhwala komanso momwe zimagwirira ntchito ndi ma ether a cellulose.
7. Njira Yosakaniza: Njira yosakaniza, kuphatikizapo nthawi yosakaniza, liwiro losakaniza, ndi dongosolo la kuwonjezera zosakaniza, zingakhudze kufalikira ndi kunyowa kwa ma ether a cellulose mu chisakanizocho. Njira zoyenera zosakaniza ndizofunikira kuti zitsimikizire kuti ma ether a cellulose akufalikira mofanana komanso kuti madzi asungidwe bwino.
8. Mikhalidwe Yophikira: Mikhalidwe yophikira, monga nthawi yophikira ndi kutentha, ingakhudze kuchuluka kwa madzi ndi kusunga madzi kwa ma ether a cellulose mu zinthu zophikira. Kuphikira koyenera ndikofunikira kuti ma ether a cellulose azitha kunyowa mokwanira ndikuthandizira kusunga madzi kwa nthawi yayitali mu chinthu cholimba.

Poganizira zinthu izi, akatswiri omanga amatha kugwiritsa ntchito bwino ma ether a cellulose ngati zinthu zosungira madzi mu matope ndi plaster kuti akwaniritse magwiridwe antchito omwe amafunidwa monga kugwira ntchito bwino, kumamatira, komanso kulimba.
