Polycarboxylate Etere Monomer HPEG /TPEG

Mtengo wa TPEG

1. Mankhwalawa ndi opanda poizoni, osakwiyitsa, ali ndi madzi abwino osungunuka, amasungunuka m'madzi ndi zosungunulira zosiyanasiyana za organic, ndipo ndizofunikira kwambiri kwa mbadwo watsopano wa makina apamwamba kwambiri a guluu.

2. Kugawa kwa maselo a mankhwalawa ndi opapatiza, zomwe zili mu polyethylene glycol ndizochepa, kusungirako zomangira ziwiri ndizokwera, ndipo ntchito ya polymerization imakhala bwino kwambiri.Kutembenuka kwa mankhwalawa ndikwambiri.Ntchito yonse ya wothandizirayo ndiyabwino kwambiri.3. The madzi kuchepetsa wothandizila apanga ndi mankhwala ali mkulu-mwachangu tinthu kubalalitsidwa ndi posungira luso, ndipo ali wabwino kubalalitsidwa zotsatira zambiri ufa zipangizo monga simenti.Ili ndi kuchuluka kwa kuchepetsa madzi komanso kugwiritsa ntchito simenti yochepa.Ubwino wa simenti wowonjezera ndi 0.2% -0.5% Konkire yochepetsera madzi, kuchepetsa madzi kumatha kufika kuposa 30%.

4. Pambuyo powonjezera madzi ochepetsera ku konkire, filimu ya adsorption imapangidwa pamwamba pa tinthu tating'ono ta simenti, yomwe imachepetsa kuthamanga kwa simenti, imapangitsa kukula kwa miyala ya simenti ya kristalo kukhala yabwino kwambiri, imachepetsa ma capillary voids a madzi. evaporation, ndi dongosolo maukonde ndi wandiweyani kwambiri, amene akhoza kusintha konkire Kulimba ndi oposa 20%.Itha kugwiritsidwa ntchito kumphamvu kwambiri (pamwamba pa C60) konkriti yamalonda.

5. Mankhwala ochepetsera madzi opangidwa ndi mankhwalawa amatha kusintha kwambiri rheology ndi pulasitiki ya konkire.Ikhoza kukwaniritsa zomangamanga za konkire mwa kudziyendetsa, kupopera, komanso popanda kugwedezeka, zomwe zingathe kuwonjezera liwiro la zomangamanga ndikuchepetsa mtengo womanga.

6. Mankhwalawa ndi obiriwira komanso okonda zachilengedwe, chloride ion okhutira: ≤0.1%.Tsatirani miyezo ya ISO14001 yapadziko lonse lapansi yoteteza zachilengedwe.

Mtengo wa HPEG

1. Izi zimakhala ndi madzi abwino kusungunuka.

2. Mankhwalawa amagwiritsa ntchito chothandizira kwambiri komanso njira yapadera yopangira.Kugawa kwa mamolekyu ndikocheperako, zomwe zili ndi ethylene glycol ndizochepa, ndipo kuchuluka kwa ma bond awiri ndikokwera.Ntchito ya polymerization imakhala yabwino kwambiri, kusinthika kwazinthu ndikwambiri, chochepetsera madzi cha polycarboxylic acid chopangidwa ndi mankhwalawa chimakhala chothandiza kwambiri, ndipo chochepetsera madzi chimakhala ndi magwiridwe antchito abwino kwambiri.

3. Magwiridwe ndi mtundu wa zochepetsera madzi zopangira:

1) Kuchita kwamtengo wapamwamba.Pankhani yokwaniritsa mlingo womwewo wochepetsera madzi, uli ndi ntchito yokwera mtengo.

2) Kusakaniza kwapang'onopang'ono komanso kuchepetsa kuchuluka kwa madzi.Madzi ochepetsa madzi omwe amamwa mowa wokhala ndi zolimba za 20% ndi kuchepetsa madzi a 1.0% (kuchuluka kwa zinthu zopangira simenti) akhoza kufika 30-35%.

3) Kusungirako bwino kwa pulasitiki.Kutayika kwa konkire pambuyo pa 1h ndikochepa.

4) Kukhalitsa kwabwino kwambiri.Zingathe kuchepetsa kumwa madzi ndikuwongolera kukhazikika kwa konkriti.

5) Green ndi kuteteza chilengedwe.Popanga zochepetsera madzi, palibe formaldehyde ndi chloride ion yovulaza chilengedwe imagwiritsidwa ntchito, ndipo zomwe zili mu sulfate ndizochepa.
