Ulwazi oluyisisekelo lwe-polymer powder

1. Umqondo oyisisekelo
I-PolyMer Powder evuselelayo yesengezo esikhulu sodaka olomile olungiselelwe njengokwenza usimende-based noma i-gypsum-based.
I-Teatisperible Latex Towdex iyi-emulser esomile futhi ehlanganiswe kusuka ku-2um yokuqala ukwakha izinhlayiya eziyindilinga ze-80 ~ 120um. Ngoba izikhala zezinhlayiya zihlanganiswe nge-inorganic, ehlulekile ukwakheka okuvinjelwe, sithola ama-polymer polymer owomile. Kulula kakhulu ukuthulula kanye nesikhwama sokugcina ezindaweni zokugcina. Lapho i-powder ixutshwe namanzi, usimende noma ngodaka olususelwa ku-gypsum, lungabuyiselwa khona, futhi izinhlayiya eziyisisekelo (2um) kuzo zizophinda zibe yi-latex yasekuqaleni, ngakho-ke ibizwa nge-latex yase-latex yasekuqaleni.

Inokubuyiselwa okuhle, kuhlaze kabusha kube yi-emulsion ekuxhumaneni namanzi, futhi inezakhiwo ezifanayo zamakhemikhali njenge-emulsion yasekuqaleni. Ngokungeza i-polymer powder ebonakalayo ku-celk-based noma i-gypsum esekelwe empuphu okomile elungiselelwe ngodaka okuxubile, izakhiwo ezahlukahlukene zodaka zingathuthukiswa, njenge:
Thuthukisa ukunamathela nokubumbana kodaka;
Ukunciphisa ukumuncwa kwamanzi kokuqukethwe kanye ne-modulus ye-elastic yezinto ezibonakalayo;
Amandla aguqukayo, ukumelana nomthelela, ukumelana nokuqina komzimba nokuqina kwezinto eziqinisiwe;
Thuthukisa ukusebenza kokwakha kwezinto zokwakha, njll.

2. Izinhlobo ze-POLMER POMPERMER POWDERS
Njengamanje, izinhlelo zokusebenza eziphambili emakethe zingahlukaniswa zihlakaze i-Latex:
I-Vinyl Acetate kanye ne-Ethylene Copolymer Rubber Powder (Vang / E), i-Ethylene neVinyl Chloride kanye neVinyl Laurate TOPERYLER TERPHER TERPOLYMERY TERPHER Terpolymerization Ruble Powder Ruble Powder I-Copolymer Rubber Powder (Vang / Veova), i-acrylate kanye ne-styrene copolymer ruble powder (a / syrete copolymer ruble powder (acryl acetate kanye ne-acrylate ne-acrylate ne-veova), i-vinyrete acid homopolymer reabber ruble powder (PBA) njll.

3. Ukwakheka kwe-polymer powder ehlakazekile
Ama-polymer powders ahlukile ajwayele ukukhishwa okumhlophe, kepha ambalwa aneminye imibala. Izithako zalo zifaka:
I-Polymer Resin: Itholakala engxenyeni eyisisekelo yezinhlayiya ze-rubber powder, futhi futhi iyingxenye esemqoka ye-polymer powder evuselelayo.
Isengezo (sangaphakathi): kanye ne-resin, idlala indima yokulungisa i-resin.
Izengezo (kwangaphandle): Izinto ezengeziwe zengezwa ukuze zithuthukise ukusebenza kwe-polymer powder ehlakazekile.
I-colloid evikelayo: ungqimba lwezinto ezibonakalayo ze-hydrophilic ezisongelwe ebusweni bezinhlayiya ze-latex evuselelayo ye-latex powder, i-colloid evikelayo ye-latex powder evuselelayo kakhulu i-polyvinyl alcohol.
Umenzeli we-Anti-Casing: Fineral Filler, ikakhulukazi esetshenziselwa ukuvikela i-abraw yerabha kusuka ekuvukeni ngesikhathi sokugcina nokuhamba kanye nokwenza lula ukugeleza kompunga noma amathangi).

4. Iqhaza le-polymer powder ehlakazekile ngodaka
I-FATEX evuselelayo ye-latex ihlakazeka kwifilimu futhi isebenza njenge-ejenti eqinisiwe njengokunamathela kwesibili;
I-colloid evikelayo idonswa uhlelo lodaka (ngeke libhujiswe ngamanzi ngemuva kokwakhiwa kwamafilimu, noma "ukuhlakazeka kwesibili";
I-polymer resin eyakha amafilimu isatshalaliswa kulo lonke uhlelo lodaka njengento eqinisayo, ngaleyo ndlela yanda ukubumbana kodaka;

5. Iqhaza le-polymer powder ehlakazekile ku-wortar emanzi:
Thuthukisa ukusebenza kokwakha;
Thuthukisa izakhiwo zokugeleza;
Khuphula i-thixotropy kanye nokumelana kwe-sag;
ngcono ukubumbana;
