Polycarboxylate Superplasticizeramaonedwa kuti ndi mkulu-ntchito admixture. Anthu nthawi zonse amayembekeza kukhala otetezeka, osavuta, ogwira ntchito bwino, komanso osinthika kuposa kusakaniza kwachikhalidwe kwa naphthalene pamapulogalamu, koma zenizeni sizili choncho. Amakumana ndi zovuta zosiyanasiyana. Kotero, ndi njira ziti zodzitetezera kuti zigwiritsidwe ntchitopolycarboxylic acidzosakaniza?
1. Polycarboxylate Superplasticizerayenera kulamulira kuchuluka kwa madzi moyenera. Kumbali imodzi, pofuna kuonetsetsa chiŵerengero cha madzi-binder, kumbali ina, chifukwapolycarboxylate superplasticizerimakhudzidwa kwambiri ndi kumwa madzi. Zizindikiro zomwe nthawi zambiri zimasonyeza ntchito zosakanikirana za konkire zimaphatikizapo fluidity, mgwirizano ndi kusunga madzi. Chifukwapolycarboxylate superplasticizerimakhudzidwa kwambiri ndi kumwa madzi, nthawi zina kumwa madzi kumangowonjezereka ndi 1kg ~ 3kg panthawi yoyesera ndi kupanga. Kutaya magazi kwakukulu, milu ya miyala yowonekera, kugwira pansi pa mphasa, ndi zina zotero, sizingatsimikizire kufanana kwa konkire kusakaniza. Chifukwa chake, kugwiritsa ntchito madzi unilateral kuyenera kuyendetsedwa mosamalitsa panthawi yopanga.
2. Kuwongolera zomwe zili mupolycarboxylic acid. Kusakwanira konkriti kumawonetseredwa ndi kutayika kwachangu, kutayika kwakukulu, komanso kuchepa kwamadzi; kuchulukirachulukira kungayambitse kutaya magazi kwambiri, kupatukana, ndi kugwira pansi. M'pofunika kuchita mayesero angapo kuti mudziwe zoyenerana bwino pakati pa kumwa madzi ndipolycarboxylate superplasticizerzomwe zili. Mfundo, ndiye kuti, mulingo woyenera kwambiri wa kumwa madzi ndi osakaniza mlingo.
3. Ndizoletsedwa kusakaniza zosakaniza za naphthalene. Malinga ndi ma projekiti osiyanasiyana, zomera zambiri zosakaniza konkire zimafunikira kugwiritsa ntchito zosakaniza za naphthalene pamene mukugwiritsa ntchitopce. Ngati zinthu zilola, ndi bwino kugwiritsa ntchito malo osiyana. Ngati gawo limodzi lili ndi zonse ziwiripolycarboxylate superplasticizerndi naphthalene, chidebe choyezerapo, mapaipi ndi chosakaniza zosakaniza ziyenera kutsukidwa bwino mukamagwiritsa ntchito njira ina, komanso tanki ya konkire iyeneranso kutsukidwa. Yeretsani ndikutsegulanso. Ngatipolycarboxylic acidndi zosakaniza zochokera ku naphthalene zimasakanizidwa ndikugwiritsidwa ntchito, zosakaniza ziwirizi zidzachitapo kanthu kuti konkire "ikhazikike mofulumira", zomwe zimapangitsa kuti galimoto yonse iwonongeke.
4.Limbikitsani kuyendera kwapolycarboxylate superplasticizerzosakaniza. Mukuyang'ana zosakaniza, tengani zitsanzo kuchokera kuzinthu zomwe zilipo zomwe zidzagwiritsidwe ntchito, ndikuyesa konkire malinga ndi zofunikira za polojekitiyi. Ngati pali vuto lililonse likupezeka, chonde funsani akatswiri aukadaulo opanga ma admixture kuti asinthe.
Mwachidule, konkirepolycarboxylic acid kuphatikizandi mtundu watsopano wa zinthu. Poyerekeza ndi zochepetsera madzi zachikhalidwe, sikuti ili ndi mlingo wochepa chabe, kuchuluka kwa kuchepetsa madzi, kutsika kwa klorini ndi kutsika kwa alkalinity, komanso kusungika kodziwikiratu. Kupititsa patsogolo kulimba kwa kapangidwe ka konkire, komanso kupangapolycarboxylate superplasticizerchochepetsera madzi ndi choyera komanso chosaipitsa. Ndi mtundu watsopano wochepetsera madzi wobiriwira komanso wokonda zachilengedwe.
