Ingaruka zo kongeramo ifu ya Redispersible polymer kumashanyarazi

Ifu ya redispersible latex ikoreshwa mugice kimwe cya JS kitarimo amazi, icyuma cya polystirene gihuza minisiteri yo kubaka insulente, minisiteri irinda ibintu byoroshye, polystirene agace kerekana ubushyuhe bwumuriro, tile yometseho, iringaniza, minisiteri yumye, ivanze, nibindi. umurima wo guhindura ibikoresho bya gorganiki byakoreshejwe cyane.

Ongeramo ifu ya redispersible latex ifu yifu irashobora kongera imbaraga, ikagira imbaraga zikomeye hamwe nubukanishi, kandi bigafasha kunoza ubukana. Ifite amazi meza yo kurwanya, gutembera, no kuramba neza. Alkaline, idashobora kwihanganira kwambara, kandi irashobora kunoza gufata neza amazi, kongera igihe cyo gufungura, no kongera igihe kirekire.

Iyo ifu ya redispersible latex ivanze neza muri poro yuzuye hanyuma ikavangwa namazi, ikwirakwizwa mubice byiza bya polymer; Gele ya sima ikorwa buhoro buhoro binyuze mumazi ya mbere ya sima, naho icyiciro cyamazi gikozwe na Ca (OH) 2 mugikorwa cya hydration. Yuzuye, mugihe ifu ya latex ikora polymer nuduce hejuru ya sima gel / ivangwa rya sima idafite amazi; nkuko sima irushijeho kuba nziza, amazi muri capillaries aragabanuka, kandi ibice bya polymer bigenda bigabanywa buhoro buhoro muri capillaries. Ibikoresho bya sima bifata neza kandi bidafite amazi bivanze hamwe nubuso bwuzuye byuzuzanya; munsi yibikorwa bya hydration reaction, kwinjiza ibice fatizo no guhumeka hejuru, amazi aragabanuka, kandi igipande cyashizwe hamwe giteranyirizwa muri firime, ihuza ibicuruzwa biva mumazi hamwe Hamwe na hamwe bagize imiterere yuzuye y'urusobe. Sisitemu yibumbiye hamwe na sima hydration hamwe na firime ya puderi ya latx irashobora kunoza imbaraga zo guhangana na putty binyuze mubikorwa bihuriweho.

Igishishwa gikoreshwa nkurwego rwinzibacyuho hagati yinkuta zo hanze no gusiga irangi ntibigomba gukomera kuruta guhomesha minomeri, bitabaye ibyo gucika bizaba byoroshye. Muri sisitemu yose yo gukumira, guhinduka kwa putty bigomba kuba hejuru kurenza ibyo bikoresho fatizo. Muri ubu buryo, ibishishwa birashobora guhuza neza no guhindura imiterere ya substrate kandi bigahindura imiterere yabyo bitewe n’ibidukikije biva hanze, bikagabanya guhangayika, kandi bikagabanya amahirwe yo guturika no gutobora igifuniko.
