Cellulose ether mu konkriti

Cellulose ether ndi mtundu wa polima wosungunuka m'madzi womwe umagwiritsidwa ntchito mosiyanasiyana, kuphatikiza konkire.Pepalali likuwunikiranso kugwiritsa ntchito cellulose ether mu konkire komanso zotsatira zake pazabwino za konkire.Pepalali likukambirana za mitundu ya ma cellulose ethers omwe amagwiritsidwa ntchito mu konkire, zotsatira zake pa zinthu za konkire, komanso ubwino ndi kuipa kogwiritsa ntchito ma cellulose ethers mu konkire.Pepalali likuwunikiranso kafukufuku waposachedwa pakugwiritsa ntchito ma cellulose ethers mu konkriti ndikupereka malingaliro pa kafukufuku wamtsogolo.

Mawu Oyamba

Ma cellulose ethers ndi mtundu wa polima wosungunuka m'madzi womwe wagwiritsidwa ntchito mosiyanasiyana, kuphatikiza konkriti.Ma cellulose ethers amagwiritsidwa ntchito kupititsa patsogolo kugwira ntchito, mphamvu, komanso kulimba kwa konkriti.Amagwiritsidwanso ntchito kuchepetsa kutsekemera kwa madzi, kukonza zomatira, komanso kuchepetsa kuchepa.Ma cellulose ether nthawi zambiri amawonjezedwa ku konkire ngati kusakaniza kwamadzimadzi kapena ufa.Pepalali likuwunikiranso kugwiritsa ntchito ma cellulose ethers mu konkriti ndi zotsatira zake pazabwino za konkire.

Mitundu ya Cellulose Ethers

Ma cellulose ethers amagawidwa m'magulu awiri akuluakulu: hydroxyethylcellulose (HEC) ndi hydroxypropylcellulose (HPC).HEC ndi ether yosakhala ionic cellulose yomwe imagwiritsidwa ntchito mu konkire kuti ikhale yogwira ntchito, kuchepetsa kutsekemera kwa madzi, ndi kuchepetsa kuchepa.HPC ndi anionic cellulose ether yomwe imagwiritsidwa ntchito kupititsa patsogolo kumamatira ndikuchepetsa kutulutsa madzi.

Zotsatira Pazinthu za Konkire

Kugwiritsiridwa ntchito kwa ma cellulose ethers mu konkire kungakhale ndi zotsatira zazikulu pa katundu wa konkire.Ma cellulose ethers amatha kusintha magwiridwe antchito a konkriti powonjezera kusuntha kwa konkriti.Izi zitha kuchepetsa kuchuluka kwa madzi ofunikira kuti mukwaniritse ntchito yomwe mukufuna.Ma cellulose ethers amathanso kuchepetsa kutsika kwamadzi ndi kuchepa kwamadzi, zomwe zingapangitse kuti konkire ikhale yolimba.Kuphatikiza apo, ma cellulose ethers amatha kukulitsa kulumikizana pakati pa konkriti ndi zinthu zina, monga chitsulo kapena matabwa.

Ubwino ndi Kuipa kwake

Kugwiritsa ntchito ma cellulose ethers mu konkriti kuli ndi zabwino zingapo.Ma cellulose ethers amatha kupititsa patsogolo kugwira ntchito kwa konkire, kuchepetsa kutuluka kwa madzi ndi kuchepa, komanso kumamatira.Kuphatikiza apo, ma cellulose ethers ndi otsika mtengo komanso osavuta kugwiritsa ntchito.Komabe, pali zovuta zina zogwiritsa ntchito ma cellulose ethers mu konkriti.Ma cellulose ethers amatha kuchepetsa mphamvu ya konkire, komanso amatha kuchepetsa mpweya wa konkire, zomwe zingachepetse kulimba kwa konkire.

Kafukufuku Wamakono

Pakhala pali kafukufuku wochuluka wochitidwa pakugwiritsa ntchito ma cellulose ethers mu konkire.Kafukufuku wasonyeza kuti ma cellulose ethers amatha kuwongolera magwiridwe antchito ndikuchepetsa kutulutsa kwamadzi komanso kutsika kwa konkriti.Kuphatikiza apo, kafukufuku wasonyeza kuti ma cellulose ethers amatha kupititsa patsogolo kumamatira kwa konkire kuzinthu zina.Komabe, pakufunikabe kufufuza kwina kuti mumvetse bwino zotsatira za ma cellulose ethers pazinthu za konkriti.

Mapeto

Ma cellulose ethers ndi mtundu wa polima wosungunuka m'madzi womwe umagwiritsidwa ntchito mosiyanasiyana, kuphatikiza konkriti.Ma cellulose ether amatha kupititsa patsogolo kugwira ntchito, mphamvu, komanso kulimba kwa konkriti.Angathenso kuchepetsa permeability madzi ndi shrinkage, ndi bwino adhesion.Pakhala pali kafukufuku wochuluka wokhudza kugwiritsa ntchito ma cellulose ethers mu konkire, koma pakufunikabe kufufuza kwina kuti mumvetse bwino zotsatira za cellulose ethers pa katundu wa konkire.
