Kusiyana Pakati pa Plasticizer ndi Superplasticizer

Plasticizers ndi superplasticizers ndi mitundu yonse ya zowonjezera za mankhwala zomwe zimagwiritsidwa ntchito posakaniza konkire kuti zitheke kugwira ntchito, kuchepetsa madzi, komanso kupititsa patsogolo zinthu zina za konkire.Komabe, amasiyana njira zawo zochitira zinthu komanso phindu lenileni lomwe amapereka.Nazi kusiyana kwakukulu pakati pa plasticizers ndi superplasticizers:

1. Njira Yochitira:
   • Plasticizers: Plasticizers ndi madzi sungunuka organic mankhwala kuti kugwirizana ndi pamwamba pa simenti particles, kuchepetsa interparticle kukopa mphamvu ndi kupititsa patsogolo kubalalitsidwa kwa tinthu ting'onoting'ono simenti mu kusakaniza.Iwo ntchito makamaka ndi lubricating ndi particles, amene amalola kwambiri fluidity ndi mosavuta akuchitira osakaniza konkire.
   • Superplasticizers: Superplasticizers, omwe amadziwikanso kuti ochepetsera madzi apamwamba kwambiri (HRWR), ndi othandiza kwambiri kuchepetsa madzi omwe amamwaza tinthu tating'ono ta simenti bwino kwambiri kuposa mapulasitiki.Amagwira ntchito potsatsa pamwamba pa tinthu tating'ono ta simenti ndikupanga filimu yopyapyala, yomwe imapanga mphamvu yonyansa pakati pa tinthu tating'onoting'ono, motero kuchepetsa chiŵerengero cha madzi ndi simenti popanda kusokoneza ntchito.
2. Kuchepetsa Madzi:
   • Plasticizers: Plasticizers nthawi zambiri amachepetsa madzi osakaniza konkire ndi 5% mpaka 15% pamene akugwira ntchito.
   • Superplasticizers: Superplasticizers amatha kukwaniritsa kuchuluka kwamadzi ochepetsera, nthawi zambiri kuyambira 20% mpaka 40%, kulola kusintha kwakukulu mu mphamvu ya konkriti, kulimba, ndi magwiridwe antchito.
3. Mlingo:
   • Plasticizers: Plasticizers amagwiritsidwa ntchito pa mlingo wochepa poyerekeza ndi superplasticizers chifukwa cha mphamvu zawo zochepetsera madzi.
   • Superplasticizers: Superplasticizers imafuna Mlingo wapamwamba kwambiri kuti muchepetse madzi omwe mukufuna ndipo nthawi zambiri amagwiritsidwa ntchito kuphatikiza ndi zosakaniza zina kuti mukwaniritse bwino ntchito.
4. Mmene Mungagwiritsire Ntchito:
   • Plasticizers: Pulasitiki makamaka imapangitsa kuti zosakaniza za konkriti zizigwira ntchito bwino, zomwe zimapangitsa kuti zikhale zosavuta kuziyika, zophatikizika, komanso kumaliza.
   • Superplasticizers: Superplasticizers amapereka mapindu ofanana ndi opangira mapulasitiki koma amatha kukwaniritsa ntchito zapamwamba komanso kuyenda, zomwe zimapangitsa kuti pakhale zosakaniza zamadzimadzi komanso zodziphatikiza zokha.
5. Mapulogalamu:
   • Plasticizers: Plasticizers amagwiritsidwa ntchito popanga konkriti kosiyanasiyana komwe kumafunikira kuwongolera komanso kuwongolera kosavuta, monga konkriti yokonzeka, konkriti yokhazikika, ndi chowombera.
   • Superplasticizers: Superplasticizers nthawi zambiri amagwiritsidwa ntchito posakaniza konkriti wapamwamba kwambiri komwe kumafunikira mphamvu zapamwamba, kulimba, komanso mawonekedwe oyenda, monga m'nyumba zokwera, milatho, ndi ntchito zomanga.

Mwachidule, pamene mapulasitiki onse ndi superplasticizers amagwiritsidwa ntchito kuti apititse patsogolo kugwira ntchito ndi kusakaniza konkriti, ma superplasticizers amapereka mphamvu zowonjezereka zochepetsera madzi ndipo amagwiritsidwa ntchito kwambiri popanga konkire yogwira ntchito kwambiri kumene mphamvu zapadera, kulimba, ndi kutuluka ndizofunikira.
