4. Vuto Lolemba Ntchito
Pakupanga, polycatroyylic acid - madzi ochepetsa madzi nthawi zambiri amasunga zosakanikirana zomwe zimachepetsa zovuta, motero amakhala ndi malo ena osokoneza bongo. Zosakaniza zogwira ntchito ndizosiyana ndi othandizira amitundu. Panthawi yopanga othandizira mpweya, zinthu zina zofunika ku m'badwo wa khola, zabwino, zotsekeka zimaganiziridwa. Zosagwira zogwira mtima izi zidzawonjezedwa kwa wothandizira wa mpweya, kotero kuti thovu lomwe limalowetsedwa mu konkriti lingakwaniritse zofunikira za mpweya popanda zovuta zomwe zimakhudza mphamvu ndi zina.
Panthawi yopanga ma polycathoxyyunic acid - madzi ochepetsa madzi, mizere ya mpweya nthawi zina imatha kukhala yokwera pafupifupi 8%. Ngati ingagwiritsidwe ntchito mwachindunji, zidzakhala zovuta pa mphamvu. Chifukwa chake, njira yomwe ikuyenera kulondera kenako ndikuyika mpweya. Opanga Deloamu nthawi zambiri amatha kuwapatsa, pomwe othandizira a mpweya nthawi zina amafunika kusankhidwa ndi ntchito yofunsira.
5. Mavuto ndi Mlingo wa Polycaxylate Madzi-Kuchepetsa Mthandizi
Mlingo wa polycaxylate madzi wothira madzi ndi wotsika, wochepetsetsa madzi ndi wokwera, ndipo malo owonda amakhala bwino, koma mavutowa amapezekanso:
① Mlingowo umakhudzidwa kwambiri pamene gawo la-simenti ndi laling'ono, ndikuwonetsa kuchuluka kwa madzi ochepetsa. Komabe, gawo la-simenti ndi lalikulu (pamwambapa 0.4), kuchuluka kwa madzi ndipo kusintha kwake sikukuwonekeratu, komwe kungakhale koonekeratu kwa a PolycaboboxyyyIC acid. Makina ogwiritsira ntchito madzi a acid kuchepetsa mankhwalawa amagwirizana ndi kubalalitsa ndikusungabe chifukwa cha kulepheretsa kumbuyo kwake. Chigawo cham'madzi chikakula, pamakhala kutalika kokwanira pakati pa mamolekyulu amadzi mu simenti, kotero danga pakati pa acid acid molekyusiridwe mwachilengedwe.
② Mukakhala kuchuluka kwa CEMEMERATION ndi yayikulu, kukopa kwa mlingo ndikowonekeratu. Pansi pazomwezo, kuchepetsedwa kwamadzi pomwe kuchuluka kwa Cememet Gree ndi <300kg / m3 ndi yaying'ono kuposa kuchuluka kwa madzi pomwe> 400kg / m3. Kuphatikiza apo, kuchuluka kwa madzi ndi kwakukulu komanso kuchuluka kwa zinthu zazing'ono ndizochepa, padzakhalanso mphamvu.
Polycattote Superplastiction imapangidwa kuti ikhale yolondola kwambiri, motero magwiridwe ake ndi mtengo wake ndioyenera kwambiri.
6. Ponena za kuphatikizira kwa polycatboxylic acid madzi-mudzichepetse othandizira
Mankhwala a polycaxtrate madzi sangathe kuphatikizidwa ndi othandizira madzi a Naphthalene. Ngati othandizira awiri ochepetsa madzi amagwiritsidwa ntchito pazida zomwezi, adzayambanso kutsukidwa bwino. Chifukwa chake, nthawi zambiri imafunikira kugwiritsa ntchito zida za polycaxomyylic acid-magetsi ochepetsa mafuta.
Malinga ndi vutoli, kugwirizana kwa wothandizila mpweya ndi polycaxtlate ndi wabwino. Cholinga chachikulu ndikuti kuchuluka kwa wothandizira mpweya ndi wotsika, ndipo kungakhale "kogwirizana ndi ma acid a acid a acid - ochepetsa madzi kuti azigwirizana. , zowonjezera. Sodium glucye mu retarder imakhalanso yogwirizana, koma ali ndi kuphatikizidwa kosavuta ndi zina zowonjezera mchere ndipo ndizovuta kuphatikiza.
7. Ponena za mtengo wa pH ya polycaboxyic acid madzi-kuchepetsa mankhwala
Mtengo wa PH of PolycaboboyIc acid - mankhwala ochepetsa madzi ndi otsika kuposa a majeremudzi ena owononga madzi ambiri, zina mwazomwe zimangokhala 6-7 zokha. Chifukwa chake, akuyenera kusungidwa mu fiberglass, pulasitiki ndi zotengera zina, ndipo sangathe kusungidwa pazitsulo zazitsulo kwa nthawi yayitali. Idzapangitsa kuti mankhwala ochepetsa a Polycakhottoxt a kuwonongeka a asidiyote, ndipo atatha nthawi yayitali a asidi, zimakhudza moyo wachitsulo ndi chitetezo cha malo osungira ndi njira yosungira.
