Mumakore achangopfuura, yakawanda resin rabha poda, yakakwirira-simba-inodzivirira mvura yerabha poda uye imwe yakachipa yakachipa yerabha poda yakaonekwa pamusika kutsiva yechinyakare VAE emulsion (vinyl acetate-ethylene copolymer), inopfapfaidzwa-yakaomeswa uye. recyclable. Dispersible latex powder, zvino ndeupi musiyano uripo pakati pe resin rabha poda uye redispersible latex poda, inogona resin rabha poda kutsiva redispersible latex poda? Yongqiang Mortar Technology Center ichakutungamira kuti uongorore muchidimbu mutsauko uripo pakati pezviviri zvereferensi yako:
1. Redispersible latex poda
Parizvino, anoshandiswa nevakawanda anoparadzirwa polima hupfu munyika ndeiyi: vinyl acetate uye ethylene copolymer rubber poda (VAC/E), ethylene uye vinyl chloride uye vinyl laurate terpolymer rubber poda (E/VC/VL), acetic acid Vinyl ester uye ethylene uye yakakwirira mafuta asidhi vinyl ester terpolymer rubber poda (VAC/E/VeoVa), izvi matatu anoraswa polymer hupfu anotonga musika wese, kunyanya vinyl acetate uye ethylene copolymer rabha hupfu VAC/E/VeoVa E, ine chinzvimbo chinotungamira mundima yepasirese uye inomiririra hunyanzvi hunhu hwepolymer hupfu hunorasika. Ichiri yakanakisa tekinoroji mhinduro maererano nehunyanzvi ruzivo nemapolymers akaiswa kune dhaka shanduko:
1. Ndiyo imwe yemapolima anonyanya kushandiswa munyika;
2. Iva neruzivo rwekushandisa zvakanyanya mumunda wekuvaka;
3. Inogona kusangana neiyo rheological properties inodiwa nedhaka (kureva kushanda kunodiwa);
4. Iyo polymer resin nemamwe mamonmers ane maitiro epasi pasi organic volatile compounds (VOC) uye yakaderera inogumbura magasi;
5. Iine maitiro ehutano hwakanaka hweUV, kupisa kwakanaka kwekudzivirira uye kugadzikana kwenguva refu;
6. Iine high saponification resistance;
7. Iine yakakura kwazvo girazi shanduko yekushisa renji (Tg);
8. Iine yakaenzana yakanaka yakazara bonding, flexibility uye mechanical properties;
9. Iva neruzivo rwakareba mukugadzirwa kwemakemikari nezve nzira yekugadzira yakagadzikana yemhando zvigadzirwa uye ruzivo mukuchengetedza kugadzikana kwekuchengetedza;
10. Zviri nyore kusanganisa nekudzivirira colloid (polyvinyl doro) nekushanda kwepamusoro.
2. Resin upfu
Mazhinji e "resin" erabha poda pamusika ane kemikari yeDBP. Iwe unogona kutarisa kukuvadza kwechinhu ichi chemakemikari, chinokanganisa basa revarume pabonde. Nhamba huru yehupfu hwerabha yakadaro inounganidzwa mumatura uye marabhoritari, uye inoshanduka kune imwe nhanho. Musika weBeijing, uyo unozivikanwa nekugadzira "rubber powder", pari zvino pabuda rudzi rwe "rabha poda" yakanyikwa muzvinonyungudutsa zvine mazita akasiyana-siyana: yakasimba-inodzivirira mvura inonamira poda, resin adhesive powder, etc. :
1. Murombo dispersibility, vamwe vanonzwa kunyorova, vamwe vanonzwa flocculent (inofanira kunge ine porous zvinhu sepiolite), uye mamwe machena uye zvishoma akaoma asi achiri kunhuwa;
2. Inonhuwa zvinopinza;
3. Mamwe mavara akawedzerwa, uye iyezvino mavara machena, yero, grey, dema, tsvuku, nezvimwewo;
4. Kuwedzerwa mari iduku zvikuru, uye kuwedzera kwetani imwe 5 ~ 12 kg;
5. Simba rekutanga rinoshamisa. Simende haina simba kwemazuva matatu, uye inogona kukanganisa bhodhi rekudzivirira uye kunamira.
6. Zvinonzi XPS board inogona kushandiswa pasina interface agent.
Kuburikidza nemasampuli akawanikwa kusvika zvino, zvinogona kugumiswa kuti i-solvent-based resin yakashongedzwa nezvinhu zvisingaremi, asi mutengesi anoda kudzivirira izwi rekuti "solvent" nemaune, saka inonzi "rubber powder"
kukanganisa:
1. Kupokana kwemamiriro ekunze kweanonyungudutsa idambudziko guru. Muzuva, inoshanduka munguva pfupi. Kunyangwe kana isiri muzuva, iyo yekubatanidza interface ichaora nekukurumidza nekuda kwekuvakwa kwegomba;
2. Kuchembera kuramba, solvent is not temperature resistance, munhu wese anozviziva;
3. Sezvo nzira yekubatanidza ndeyekupedza kushandiswa kwebhodhi rekudzivirira, pane zvinopesana, inoparadzawo kusungirirwa kwekubatanidza. Kana pane dambudziko muchikamu chekupedzisira, kukanganisa kuchava kunouraya;
4. Hapana muenzaniso wekunyorera kunze kwenyika. Neruzivo rwakakura rweiyo yakakosha indasitiri yemakemikari kunze kwenyika, hazvigoneke kusawana ichi chinyorwa.
pfupiso:
Dispersible polymer poda:
1. The redispersible latex powder product is a water-soluble redispersible powder, iyo inonzi copolymer ye ethylene uye vinyl acetate, uye inoshandisa polyvinyl doro sekudzivirira colloid.
2. VAE redispersible latex powder ine firimu-inogadzira zvinhu, 50% aqueous solution inoumba emulsion, uye inoumba plastiki-yakafanana firimu mushure mekuiswa pagirazi kwemaawa makumi maviri nemana.
3. Iyo firimu yakaumbwa ine kumwe kushanduka uye kusagadzikana kwemvura. Inogona kusvika pamitemo yenyika.
4. Iyo redispersible latex powder ine kushanda kwepamusoro: ine kukwirira kwepamusoro kukwanisa, kushanda kwakasiyana uye kunoshamisa kwekushanda kwemvura, simba rakanaka rekubatanidza, rinopa dhaka nepamusoro-soro yealkali, uye inogona kuvandudza kunamatira uye flexural simba redhaka. , plastiki, kupfeka kuramba uye kuvaka, ine kusimba kwakasimba mu-anti-cracking mortar.
Resin powder:
1. Resin rubber powder rudzi rutsva rwekugadzirisa rubber, resin, macromolecular polymer, pasi rabha poda nezvimwe zvinhu.
2. Resin rabha poda ine general durability, abrasion resistance, urombo dispersibility, vamwe vanonzwa flocculent (inofanira kunge iri porous material like sepiolite), uye white powder (asi ine pungent smell yakafanana neparafini) ).
3. Dzimwe resin powders dzinosvibisa kubhodhi, uye kudzivirira mvura hakuna kunaka.
4. Kuramba kwemamiriro ekunze uye kudzivirira kwemvura ye resin rubber powder zvakaderera pane zve latex powder. Kuramba kwemamiriro ekunze idambudziko guru. Muzuva, inoshanduka munguva pfupi. Kunyangwe kana isiri muzuva, iyo yekubatanidza interface, Sezvo iri mhango yekuvaka, inowora nekukurumidza.
5. Resin rubber powder haina kuumbwa, kana kushanduka. Zvinoenderana nechiyero chekuongorora chekunze chekudzivirira dhaka kumadziro ekunze, chete mwero wekuparadza wepolystyrene board unosangana nechiyero. Zvimwe zviratidzo hazvisi kusvika pachiyero.
6. Resin poda inogona kushandiswa chete pakubatanidza polystyrene mapuranga, kwete kusungirirwa kwevitrified beads uye mapuranga asingasviki moto.
