youma ufa ❖ kuyanika

Zopangira matope a polima okhala ndi zofunikira zapamwamba kuti zitheke

4.Zomwe zimapangidwira

Ili ndi ntchito yabwino kwambiri yopanda madzi, mphamvu yomangirira bwino, imawonjezera kusungunuka kwa matope ndipo imakhala ndi nthawi yayitali yotseguka, imapatsa matope kukana kwambiri kwa alkali, komanso kumamatira, kumamatira, kulimba kwamphamvu, pulasitiki komanso kukana kwamatope. Kuphatikiza pakuchita bwino komanso kugwirira ntchito, imakhala ndi kusinthasintha kwamphamvu mumatope osinthika oletsa kukwapula.

5.The udindo wa redispersible polima ufa

Ufa wa polima wotayika umamwazikana mufilimu ndipo umakhala ngati cholimbikitsira ngati chomatira chachiwiri.

Colloid yoteteza imatengedwa ndi matope ndipo sichidzawonongedwa ndi madzi kapena "kubalalitsidwa kwachiwiri" pambuyo popanga filimu.

Utoto wopanga filimu wopangidwa ndi polima umakhala ngati chilimbikitso chomwe chimagawidwa mumatope onse, potero kumawonjezera mgwirizano wamatope.

6.Ntchito yomwaza ufa wa polima mumatope

The redispersible latex ufa amamwazikana mu filimu ndi amachita ngati yachiwiri zomatira kuonjezera adhesion;

Colloid yoteteza imatengedwa ndi matope (sidzawonongedwa ndi madzi pambuyo popanga mafilimu. Kapena omwazika kawiri);

Mafilimu opangidwa ndi polima utomoni amagawidwa mu matope onse monga kulimbikitsa zinthu, motero kumawonjezera mgwirizano wa matope.

Ntchito ya dispersible polima ufa mu chonyowa matope

Limbikitsani ntchito yomanga

Sinthani mawonekedwe oyenda

Wonjezerani thixotropy ndi sag resistance

onjezerani mgwirizano

Maola otsegulira owonjezera

Limbikitsani kusunga madzi

Ntchito redispersible ufa pambuyo matope kuchiritsa

Kuwonjezeka kwamphamvu kwamphamvu (zomatira zowonjezera m'makina a simenti);

Kupititsa patsogolo mphamvu ya flexural;

kuchepetsa zotanuka modulus;

Kupititsa patsogolo deformability;

Wonjezerani kachulukidwe kazinthu;

Kupititsa patsogolo kukana kuvala;

Kupititsa patsogolo mphamvu zogwirizana;

Kuchepetsa kuya kwa carbonation;

Chepetsani kuyamwa kwamadzi

7.Mmene katundu wa RDP amasungidwa

Dispersible polima ufa VAE uyenera kusungidwa pamalo ozizira komanso owuma. Nthawi yovomerezeka yogwiritsira ntchito ndi miyezi isanu ndi umodzi, choncho gwiritsani ntchito mwamsanga m'chilimwe. Kusungirako kutentha kwambiri ndi chinyezi kumawonjezera mwayi wophika. Mukatsegula thumba, chonde mugwiritseni ntchito mwamsanga, mwinamwake muyenera kusindikiza thumba kuti musatenge chinyezi kuchokera mumlengalenga. Osaunjika pamapallet kapena kusunga zikwama zamapepala mopanikizika kwambiri kwa nthawi yayitali kuti musagwe.
