Kusiyana Pakati pa Plasticizer ndi Superplasticizer

Mapulasitiki ndi ma superplasticizer onse ndi mitundu ya zowonjezera za mankhwala zomwe zimagwiritsidwa ntchito mu zosakaniza za konkriti kuti ziwongolere kugwira ntchito, kuchepetsa kuchuluka kwa madzi, ndikuwonjezera mphamvu zina za konkriti. Komabe, zimasiyana mu njira zawo zogwirira ntchito komanso zabwino zomwe zimapereka. Nazi kusiyana kwakukulu pakati pa mapulasitiki ndi ma superplasticizer:

1. Njira Yogwirira Ntchito:
   • Mapulasitiki: Mapulasitiki ndi zinthu zachilengedwe zomwe zimasungunuka m'madzi zomwe zimagwirizana ndi pamwamba pa tinthu ta simenti, kuchepetsa mphamvu zokopa pakati pa tinthu ta simenti ndikuwongolera kufalikira kwa tinthu ta simenti mu chisakanizocho. Amagwira ntchito makamaka popaka mafuta tinthu ta simenti, zomwe zimathandiza kuti chisakanizo cha simenti chikhale chosasunthika komanso kuti chikhale chosavuta kugwiritsa ntchito.
   • Ma Superplasticizer: Ma Superplasticizer, omwe amadziwikanso kuti ma high-range water reducers (HRWR), ndi othandizira kwambiri kuchepetsa madzi omwe amafalitsa tinthu ta simenti bwino kwambiri kuposa ma plasticizer. Amagwira ntchito pomamatira pamwamba pa tinthu ta simenti ndikupanga filimu yopyapyala, yomwe imapanga mphamvu yayikulu yonyansa pakati pa tinthu ta simenti, motero amachepetsa chiŵerengero cha madzi ndi simenti popanda kusokoneza kugwira ntchito.
2. Kuchepetsa Madzi:
   • Mapulasitiki: Mapulasitiki nthawi zambiri amachepetsa kuchuluka kwa madzi mu zosakaniza za konkire ndi 5% mpaka 15% pamene akupitiriza kugwira ntchito bwino.
   • Ma Superplasticizer: Ma Superplasticizer amatha kuchepetsa madzi kwambiri, nthawi zambiri amakhala pakati pa 20% mpaka 40%, zomwe zimapangitsa kuti mphamvu ya konkriti ikhale yolimba, yolimba, komanso yogwira ntchito bwino.
3. Mlingo:
   • Mapulasitiki: Mapulasitiki nthawi zambiri amagwiritsidwa ntchito pamlingo wochepa poyerekeza ndi mapulasitiki apamwamba chifukwa cha mphamvu zawo zochepetsera madzi pang'ono.
   • Ma Superplasticizer: Ma Superplasticizer amafunika mlingo wokwera kuti achepetse madzi omwe amafunidwa ndipo nthawi zambiri amagwiritsidwa ntchito limodzi ndi zinthu zina zosakaniza kuti agwire bwino ntchito.
4. Zotsatira pa Kugwira Ntchito:
   • Mapulasitiki: Mapulasitiki makamaka amathandiza kuti zosakaniza za konkire zigwire ntchito bwino komanso kuti zizitha kuyenda bwino, zomwe zimapangitsa kuti zikhale zosavuta kuziyika, kuzigwira bwino, komanso kuzimaliza.
   • Ma Superplasticizer: Ma Superplasticizer amapereka maubwino ofanana ndi ma plasticizer koma amatha kugwira ntchito bwino komanso kuyenda bwino, zomwe zimathandiza kupanga zosakaniza za konkriti zomwe zimakhala ndi madzi ambiri komanso zodzigwirizanitsa zokha.
5. Mapulogalamu:
   • Mapulasitiki: Mapulasitiki amagwiritsidwa ntchito kwambiri m'malo osiyanasiyana ogwiritsira ntchito konkriti komwe kumafunika kugwirira ntchito bwino komanso kosavuta kugwiritsa ntchito, monga konkriti yokonzeka kusakaniza, konkriti yokonzedwa kale, ndi shotcrete.
   • Ma Superplasticizer: Ma Superplasticizer nthawi zambiri amagwiritsidwa ntchito mu zosakaniza za konkriti zapamwamba komwe kumafunika mphamvu yapamwamba, kulimba, ndi makhalidwe oyenda bwino, monga m'nyumba zazitali, milatho, ndi mapulojekiti omanga.

Mwachidule, ngakhale kuti mapulasitiki ndi ma superplasticizer onse amagwiritsidwa ntchito kukonza magwiridwe antchito ndi magwiridwe antchito a zosakaniza za konkire, ma superplasticizer amapereka mphamvu zambiri zochepetsera madzi ndipo amagwiritsidwa ntchito kwambiri pa ntchito za konkire yogwira ntchito bwino komwe mphamvu, kulimba, ndi kuyenda bwino ndizofunikira kwambiri.
