Kodi njira zama ethel ether ngati zodetsa zowuma?

Chimodzi mwazinthu zazikulu kwambiri pakati pa matope owuma ndi matope omwe ali ndi matope amasinthidwa ndi zowonjezera zochepa zamankhwala. Kuonjezera mtundu wina wa matope owuma amatchedwa kusintha koyambirira, kuwonjezera ziwiri kapena zingapo zowonjezera ndi kusintha kwachiwiri. Mtundu wa matope wowuma umatengera kusankha koyenera komanso kolumikizana ndi kufanana ndi zinthu zosiyanasiyana. Zowonjezera zamankhwala ndizokwera mtengo ndipo zimalimbikitsa kwambiri matope owuma. Chifukwa chake, pakusankhidwa kwa zowonjezera, kuchuluka kwa zowonjezera ziyenera kukhala pamalo oyamba. Izi ndizoyambira mwachidule kusinthidwa kwa mankhwala owonjezera ma cellulose ether ether.

Cellulose ether imadziwikanso kuti REOOROIFIFIFIFIFIFIFIFIFAIRIFIFIFIFIFAIRIFIFIFIFAIRIFIFER Mtundu wophatikizika womwe umagwiritsidwa ntchito kusintha matope atsopano, pafupifupi omwe amagwiritsidwa ntchito m'matope amtundu uliwonse. Zinthu zotsatirazi ziyenera kugwiritsidwa ntchito posankha mitundu ndi kuchuluka komwe kuwonjezeredwa:

(1) Kusunga kwamadzi pamalo osiyanasiyana;

(2) Kukula, mamasuki;

.

(4) Fomu ndi kuchuluka kwa chikondwerero;

.

(6) Kutha kwa chilengedwe, momwe kuperewera kwathunthu.

Kuphatikiza pa kuwonjezera cellulose ether mu matope owuma (monga methyl cellulose ether ether), zingawonjezerenso vinyl Polyvinyl acid Elster, ndiye kuti, kusintha kwachiwiri. Chingwe chosinthira matope (simenti, gypsum) amatha kutsimikizira kulimba kwambiri, koma sikuthandiza kwambiri kukhala ndi mphamvu yakuchepa komanso kubisala mphamvu. Vinyl polyvinyl ester imamanga zotanuka zamiyala yamiyala yamiyala, pangani matope amatha kunyamula katundu wambiri, kusintha kuvala kukana. Zatsimikiziridwa ndi zomwe zimachitika powonjezera kuchuluka kwa methyl cellulose ether ndi matope opota, zokongoletsera zokongoletsera, zokongoletsera zokongoletsera zowoneka bwino ikhoza kukonzedwa. Kuphatikiza awiriwo sikungakhale kokha kungosintha matope, komanso kukonza bwino ntchito yomanga.

Pogwiritsa ntchito, pofuna kukonza magwiridwe athunthu, ndikofunikira kugwiritsa ntchito ma admix angapo. Masewera abwino kwambiri pakati pa chowonjezera, gawo loyenera, gawo, lomwe limachokera kwa matope osiyanasiyana Monga fiberi imodzi yokhayo, pakuwonjezera zomata za matope, kuchepetsa kuchuluka kwa stratition nthawi yomweyo, komabe, kugwiritsa ntchito matope amawonjezeka kwambiri ndikusungidwa mu slurry, komwe kumabweretsa kuchepa kwamphamvu. Pamene wothandizira wa mlengalenga atawonjezeredwa, kuchuluka kwa matope ndi kugwiritsa ntchito kwamadzi kumatha kuchepetsedwa kwambiri, koma mphamvu yovuta ya matope idzachepera chifukwa cha thovu zambiri. Sinthani matongeya matonge abwino, ndikupewa kuvulaza katundu wina, kulimba kwa matonge ndi matope omwe amafunikira , kutetezedwa kwa chilengedwe, ndi zina zambiri kuchokera ku kuchepetsedwa kwamadzi, mafakisoni amadzi, madzi okutira ndi mpweya, ndikofunikira kutenga njira zokwanira kuti ayambe ndi kugwiritsa ntchito akwatire.
