Uruhare rwifu ya polymer isubirwamo ifu ya putty

Uruhare rwakugarurwapolymerifuifu ya putty: ifite imbaraga zifatika hamwe nubukanishi, kutagira amazi meza, kwinjirira neza, hamwe no kurwanya alkali nziza kandi ikarwanya kwambara, kandi irashobora guteza imbere gufata amazi no kongera igihe cyo gufungura igihe kirekire.

1. Ingaruka ya minisiteri ivanze

1) Kunoza ubwubatsi.

2) Kubika amazi yinyongera kugirango atezimbere sima.

3) Kongera ubushobozi.

4) Irinde guturika hakiri kare.

2. Ingaruka zo gukomera

1) Mugabanye modulike ya elastike ya minisiteri kandi wongere ubwuzuzanye nigice fatizo.

2) Ongera guhinduka no kurwanya gucika.

3) Kunoza kurwanya ifu igwa.

4) Hydrophobique cyangwa kugabanya kwinjiza amazi.

5) Ongera gufatira kumurongo fatizo.

Ifu ya redispersible latex ikora polymer emulsion ihuye namazi.Mugihe cyo kuvanga no gukama, emulion yongeye kubura umwuma.Ifu ya latex ikora mu ifu ya putty, kandi uburyo bwo gukora sisitemu yo gutunganya sima hydrata na firime ya latx ya firime yarangiye mubyiciro bine:

HenIyo ifu ya redispersible latex ivanze neza n'amazi mu ifu ya putty, ikwirakwizwa mubice byiza bya polymer;

Gel Gel ya sima igenda ikorwa buhoro buhoro binyuze mumazi ya mbere ya sima, icyiciro cyamazi cyuzuyemo Ca (OH) 2 cyakozwe mugihe cyo gutunganya amazi, kandi uduce twa polymer twakozwe nifu ya latex dushyira hejuru ya gel ya sima / ivangwa rya sima idafite amazi;

③ Nkuko sima irushijeho kuba nziza, amazi yo mu myobo ya capillary aragabanuka, kandi ibice bya polymer bigenda bifungirwa buhoro buhoro mu mwobo wa capillary, bigakora igipande gipfunyitse cyane hejuru ya sima gel / ivangwa rya sima idafite amazi hamwe nuwuzuza;

④ Mugihe cyibikorwa bya hydration reaction, kwinjiza ibice fatizo no guhumeka hejuru yubushuhe, ubuhehere buragabanuka, kandi ibice byashizwe hamwe bikusanyirizwa hamwe muri firime yoroheje, kandi ibicuruzwa bivamo hydrata bifatanyirizwa hamwe kugirango bibe urwego rwuzuye.Sisitemu ikomatanya ikorwa na sima hydrata hamwe na firime ya porojeri ya latx itezimbere imbaraga zo guhangana na putty.

Urebye muburyo bufatika, imbaraga za putty zikoreshwa nkurwego rwinzibacyuho hagati yimiterere yo hanze hamwe no gutwikisha urukuta rwo hanze ntibigomba kuba hejuru kurenza ibya minisiteri yo guhomeka, bitabaye ibyo byoroshye kubyara.Muri sisitemu yose yo gukumira, guhinduka kwa putty bigomba kuba hejuru kurenza ibya substrate.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.
