Ulwazi oluyisisekelo lwe-polymer powder

1. Umqondo oyisisekelo

I-polymer polymer powderIsengezo esikhulu se-powder eyomile elungiselelwe ngodaka oluxutshwe kasimende olunjengesimende 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 ehlukile ku-celk-based noma i-gypsum esekelwe empuphu okomile elungiselelwe ngodaka, 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 ne-Ethylene Copolymer Rubber Powder (Vac / E), i-Ethylene ne-Vinyl Chloride kanye neVinyl Laurate Terryery Copolymer irompur powder (VINYL acid aciny vinyl perber verl terpolymerization ster jerpolymymerization ruble powder (vap / E / I-Veova), i-vinyl acetate kanye ne-aciny acid aciny vinyl ester copolymer rubber powder (Vang / Veova), i-acrylate kanye ne-acetate irabha irowuber powder (acryletate aciny vinyl ester torpolymer ruble powder (Vac / A / I-Veova), i-vinyl acetate homopolymer ruble powder (PVAC), i-styrene ne-buthaniene copolymer ruble powder (SBR), 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;
