Imisebenzi eyisithupha ye-polymer powder ehlakazekile

I-Redispersergeble Powter powder iyimpuphu egeleza mahhala ye-polymer emhlophe engavunyelwa kabusha futhi ihlakazeke emanzini ukwenza i-emulsion ezinzile. Ingahlanganiswa nezinye izinto eziyimpuphu ezinjengesimende, isihlabathi, aggregate ongasindi, njll. Efektri yokukhiqiza ngokuya ngesilinganiso esisezingeni eliphakeme futhi esisebenziseka kalula, esinganciphisa ukwakhiwa kwesayithi. Iphutha nokuphazamiseka lapho kuxuba nokulinganisa ne-emulsion.

Imisebenzi eyisithupha ye-polymer powtmer:

1. Thuthukisa amandla anamathela nokuhlangana
Emikhiqizweni eyomile yodaka eyomile, kuyadingeka kakhulu ukwengeza i-polymer powder ehlukile. Kusobala kakhulu ukuthuthukisa amandla eBonding kanye nokubumbana kwezinto. This is due to the penetration of the polymer particles into the pores and capillaries of the cement matrix, and the formation of good cohesive strength with the cement after hydration. Ngenxa yokunamathela okuhle kakhulu kwe-polymer resin uqobo, kungathuthukisa ukunamathela kwemikhiqizo yodaka kasimende ukuze ufake imikhiqizo yodaka, ikakhulukazi ama-inorganic anjengesimende ahlanganiswe nosimende ahlanganiswe nama-organic advertrates anjengezinkuni, i-fiber, PVC kanye ne-EPS. Ukuthuthuka kokusebenza kabi kunomphumela osobala.

2. Thuthukisa ukugoba nokuphikisana nokuqina
Ku-Skeleton eqinile eyakhiwa yi-hydration kasimende kasimende, ifilimu ye-polymer inanya futhi inzima. Phakathi kwezinhlayiya zodaka ngodaka, isebenza njengokuhlanganiswa okungahambi kahle, okungamelana nemithwalo emibi kakhulu futhi inciphise ukucindezela, ukwenza ukumelana nokugoba okusheshayo kuyathuthukiswa.

3. Thuthukisa ukumelana nomthelela
I-polymer powder evuselelayo, i-thermoplastic resin. Ifilimu ethambile ehlanganiswe ebusweni bezinhlayiya zodaka, ezingadonsela umthelela wamandla angaphandle futhi iphumule ngaphandle kokuphuka, ngaleyo ndlela enze ngcono ukumelana nomthelela wodaka.

Okwesine, thuthukisa i-hydrophobicity futhi unciphise izinga lokufakwa kwamanzi
Ukungeza i-distmerble polymer powder kungathuthukisa i-miscream kasimende. I-polymer yayo yakha inethiwekhi engenakuphikiswa enqubweni ye-Conment hydration, ivala i-capillary kwijeli yesimende, ivimba ukumuncwa kwamanzi, kuvimbela ukungena kwamanzi, ngaleyo ndlela kuthuthukise ukungakhululeki.

5. Thuthukisa ukumelana nokuqina kokuqina nokuqina
Ukungezwa kwe-polymer powder ehlakazekile kungakhuphula isibopho esiminyene phakathi kwezinhlayiya zodaka ngosimende kanye nefilimu ye-polymer. Ukuthuthukiswa kwamandla okubumbana kuthuthukisa ukuvumelana kahle kodaka ukumelana nokuxineka kwe-shear, ukuze izinga lokugqoka lincishisiwe, ukumelana nokugqokwa kwento kuthuthukile, futhi impilo yenkonzo yodaka luyaqhubeka isikhathi eside.

6. Thuthukisa ukuqina kwe-freeze-thaw futhi ngempumelelo ukuvikela ukuqhekeka kwezinto ezibonakalayo
I-Platex evuselelayo ye-latex, i-plastity ye-resin yayo ye-thermoplastic, ingakunqoba ukulimala kokunwetshwa okushisayo nokugqwayiza okubangelwa ukuguqulwa kokushisa kokushisa kwezinto zohlobo lwesimende. Ukunqoba ukushiyeka kosimende olula ngodaka ngokomisa ama-shrinkage defformate kanye nokuqhekeka okulula, kungenza okuguquguqukayo, ngaleyo ndlela kuthuthukise ukuqina kwesikhathi eside kwezinto ezibonakalayo.
