Zotsatira za ether ya cellulose pa matope odziyimira pawokha

Ma matope odziyimira okha amadalira kulemera kwawo kuti apange maziko athyathyathya, osalala komanso olimba pa substrate, zomwe zimapangitsa kuti zipangizo zina ziikidwe kapena kulumikizidwa, pomwe zikugwira ntchito bwino kwambiri. Chifukwa chake, kusinthasintha kwakukulu ndi khalidwe lofunika kwambiri la matope odziyimira okha. Ayeneranso kukhala ndi mphamvu yosungira madzi ndi mgwirizano, osazungulira kapena kulekanitsa, komanso azikhala ndi kutentha kochepa komanso kutentha kochepa.

Mtondo wodziyimira pawokha umafuna kusinthasintha kwabwino, koma kuyenda kwa matope a simenti nthawi zambiri kumakhala 10-12cm yokha; cellulose ether ndiye chowonjezera chachikulu cha matope osakanikirana kale, ngakhale kuchuluka komwe kumawonjezeredwa kumakhala kochepa kwambiri, kumatha kusintha kwambiri magwiridwe antchito a matope, zomwe zingathandize kuti matope azigwira ntchito bwino, kugwira ntchito bwino, kugwira ntchito bwino komanso kusunga madzi. Ili ndi gawo lofunika kwambiri pa ntchito ya matope osakanikirana kale.

1 Kutuluka madzi

Cellulose ether imakhudza kwambiri kusunga madzi, kusinthasintha, komanso kugwira ntchito kwa matope. Makamaka ngati matope odziyimira pawokha, kusinthasintha kwa madzi ndi chimodzi mwa zizindikiro zazikulu zowunikira momwe matope amagwirira ntchito. Kusinthasintha kwa madzi a matope kumatha kusinthidwa posintha kuchuluka kwa cellulose ether poganizira kuti matopewo ndi abwinobwino. Kuchuluka kwambiri kwa madzi kumachepetsa kusinthasintha kwa madzi a matope, chifukwa chake, kuchuluka kwa cellulose ether kuyenera kulamulidwa mkati mwa malire oyenera.

2 Kusunga madzi

Mtondo wosunga madzi ndi chizindikiro chofunikira cha kukhazikika kwa zigawo zamkati mwa matope a simenti. Kuti zinthu za gel zikhale ndi madzi okwanira, kuchuluka koyenera kwa ether ya cellulose kungagwiritsidwe ntchito kwa nthawi yayitali kuti madzi asunge mu matope. Nthawi zambiri, pamene kuchuluka kwa ether ya cellulose kukuwonjezeka, kusunga madzi kwa matope kumawonjezekanso. Kuphatikiza apo, kukhuthala kwa ether ya cellulose kumakhudza kwambiri kusunga madzi kwa matope; kukhuthala kwakukulu, kumakhala bwino kusunga madzi.

3 Nthawi yokhazikitsa

Cellulose ether imaletsa matope. Pamene kuchuluka kwa cellulose ether kukwera, nthawi yoyika matope idzatalikitsidwa. Ndipo chifukwa cha kuchuluka kwa cellulose ether, mphamvu yoyambirira ya hydration ya simenti imakhala yodziwikiratu.

4 Mphamvu yopindika ndi mphamvu yopondereza

Kawirikawiri, mphamvu ndi chimodzi mwazofunikira kwambiri poyesa kusakaniza kwa simenti yokhazikika. Mphamvu yokakamiza ndi mphamvu yopindika ya matope zidzachepa pamene kuchuluka kwa cellulose ether kukuwonjezeka.
