Chidziwitso choyambirira cha kufalitsa polmer ufa

1.

Kubwezeretsedwa Polimer PolyderNdiwowonjezera matope owuma owuma monga matope osakanizika ngati simentam kapena gypsum.

Kubwezeredwa ufa wa latx ndi polymer emulsion komwe kumawuma ndikuwuma ndikuchokera koyambirira kwa 20 ~ 120um. Chifukwa mawonekedwe a tinthu tating'onoting'ono ndi ufa wa zinthu zachilengedwe, timapeza ufa wowuma. Ndizosavuta kutsanulira ndi chikwama chosungirako m'malo osungiramo nyumba. Pamene ufa umasakanizidwa ndi madzi, simenti kapena matope a gypsum, ndipo tingathe kubwezeredwanso, ndipo tinthu toyambitsa matenda (2um) mkati mwake zimapangidwanso mu boma lofanana ndi latx yoyambirira.

Ili ndi kukonzanso kwabwino, kumabalalikanso mu emulsion pakulumikizana ndi madzi, ndipo ali ndi mankhwala omwewo monga emulsion yoyambirira. Powonjezera kufalitsa polima ufa ku ufa kapena matope owuma-gypsum okhazikika, zinthu zosiyanasiyana za matope zitha kusintha, monga:

Sinthani chotsatira ndi chiyanjano cha matope;

Chepetsani mayamwidwe azomwe ndi zotanuka za nkhaniyi;

Kutha mphamvu, kukana kwamphamvu, abrasion kukana ndi kulimba kwa zinthu zolimbitsa thupi;

Sinthani magwiridwe antchito, etc.

2. Mitundu ya kufalitsa polima

Pakadali pano, ntchito zazikulu pamsika zitha kugawidwa kuti zitheke posachedwa

Vinyl acetate ndi ethyler cololymer ufa (ne / e), ethylene ndi vanyl chloride ndi ma vinyl Veova), vinyl acetate ndi mafuta ochulukirapo acid vinyl esth esthely ecelely ecelely esthely esthely esthel esthel esthel esthel esthel esthely esthely essolymer ufa wa mphira (ne / Veova), yinill acetate homopolymer ufa (PVAC), styrene ndi yaniene Curolymer Placker ufa (SBR), etc.

3. Kupanga kwa poltermer polder

Kufatsa ufa wa polima nthawi zambiri kumakhala ufa woyera, koma ochepa ali ndi mitundu ina. Zosakaniza zake ndi monga:

Polymer Resin: ili mkati mwa gawo la mphira wa mphira, ndipo ndi gawo lalikulu la ufa wobwezeretsera.

Zowonjezera (zamkati): Pamodzi ndi utomoni, imagwira ntchito yosintha maten.

Zowonjezera (zakunja): Zipangizo zowonjezera zimawonjezeredwa kuti ziwonjezere magwiridwe antchito omwazika ndi ufa.

Colloid colloid: wosanjikiza wa zinthu zokutira utakulungidwa pamwamba pa tinthu tating'onoting'ono tofanana ndi tinthu tating'onoting'ono tofana, zotetezera za ufa wambiri ndi mowa wa polyvinyl.

Anti-Caing Agent: Migodi Yabwino Kwambiri, makamaka kuteteza ufa wa mphira kuti usayendetse ufa wa mphira (kutaya m'matumba a pepala kapena).

4. Udindo wobalalitsa polmer ufa mu matope

Ufa wokwezeka watchx umabalalika mufilimu ndipo amachita ngati wothandizira wolimbikitsa ngati zomata zachiwiri;

Colloid yoteteza imalowetsedwa ndi dongosolo la matope (sidzawonongedwa ndi madzi atatha kupanga filimu, kapena "kubalalika kwachiwiri";

Pulogalamu yopanga mafilimu imagawidwa mu matope mu matope monga zinthu zolimbitsa, potero ndikuwonjezera chimondo wa matope;

5. Udindo wa kufalitsa polima ufa mu matope onyowa:

Sinthani zomanga;

Sinthani katundu wotsika;

Kuchuluka kwa thixotropy ndi kukana kwa Aleg;

Patsani Chibasion;
