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. yakagadzirwa nehupfu yerabha inogona kushandiswa zvakare.Yakapararira latex poda, saka ndeupi musiyano uripo pakati pehupfu hweresin uye redispersible latex poda, inogona here resin poda kutsiva redispersible latex poda?
Ongorora muchidimbu musiyano uripo pakati pezviviri izvi kuti utaure:
01. Redispersible latex powder
Parizvino, the redispersible latex powders anoshandiswa zvakanyanya munyika ndeiyi: vinyl acetate uye ethylene copolymer powder (VAC/E), ethylene, vinyl chloride uye vinyl laurate ternary copolymer powder (E/VC/VL), acetic acid Vinyl ester, ethylene. uye yakakwira fatty acid vinyl ester ternary copolymer poda (VAC/E/VeoVa), aya matatu anodispersible latex poda anotonga musika wese, kunyanya vinyl acetate uye ethylene copolymer poda VAC/EE, inobata chinzvimbo chekutungamira mumunda wepasi rose uye inomiririra tekinoroji. hunhu hwe redispersible polymer hupfu.Ichiri yakanakisa tekinoroji mhinduro maererano nehunyanzvi ruzivo nemapolymers akaiswa kune dhaka shanduko:
1. Ndiyo imwe yemapolima anonyanya kushandiswa munyika;
2. Chiitiko chekushandisa mumunda wekuvaka ndicho chakanyanya;
3. Inogona kusangana ne rheological properties inodikanwa nedhaka (kureva, inodiwa inovaka);
4. Iyo polymer resin ine mamwe monomers ine maitiro eiyo yakaderera organic volatile matter (VOC) uye yakaderera inogumbura gasi;
5. Iine maitiro ehutano hwakanaka hweUV, kupisa kwakanaka kwekudzivirira uye kugadzikana kwenguva refu;
6. Kuramba kwakanyanya kune saponification;
7. Iine yakakura kwazvo girazi shanduko yekushisa renji (Tg);
8. Iine yakanyatsonaka yakawedzera kusungirirana, kuchinjika uye michina zvinhu;
9. Iva neruzivo rwakareba mukugadzirwa kwemakemikari ekuti ungagadzira sei zvakagadzikana zvigadzirwa zvemhando yepamusoro uye ruzivo mukuchengetedza kugadzikana kwekuchengetedza;
10. Zviri nyore kwazvo kusanganisa nekudzivirira colloid (polyvinyl doro) nekushanda kwepamusoro.
02. Resin poda
Yakawanda ye "resin" rubber powder pamusika ine kemikari yeDBP.Iwe unogona kutarisa kukuvadza kwechinhu ichi chemakemikari, chinokanganisa basa revarume pabonde.Huwandu hukuru hwemhando iyi yehupfu yerabha inounganidzwa mudura uye murabhoritari, uye ine kumwe kushanduka.Musika weBeijing, uyo unozivikanwa nekuwanda kwe "rabha poda", ikozvino ine mazita akasiyana-siyana e "rabha poda" yakanyikwa muzvinonyungudutsa: yakasimba-yakasimba mvura isingaite rabha poda, resin rabha poda, 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 zvakaipa;
2. Kunonhuwa zvakanyanya;
3. Mamwe mavara akawedzerwa, uye mavara ari kuoneka iye zvino machena, yero, grey, dema, tsvuku, nezvimwewo;
4. Kuwedzera kwekuwedzera kuduku zvikuru, uye chiyero chekuwedzera kune imwe tani ndeye 5-12 kg;
5. Simba rekutanga rakanaka zvinoshamisa.Simenti haina simba mumazuva matatu, uye bhodhi rekudzivirira rinogona kusvibiswa uye rakanamatira;
6. Zvinonzi XPS board haidi mumiriri weinterface;
Kuburikidza nemienzaniso yakawanikwa kusvika ikozvino, inogona kugumiswa kuti i-solvent-based resin yakashambadzirwa nezvinhu zvinopenya, asi mutengesi anoda kudzivisa nemaune shoko rokuti "solvent", saka inonzi "rubber powder".
kukanganisa:
1. Kupokana kwemamiriro ekunze kweanonyungudutsa idambudziko guru.Muzuva, inoputika munguva pfupi.Kunyangwe kana isiri muzuva, iyo yekubatanidza interface ichaora nekukurumidza nekuda kwekuvakwa kwegomba;
2. Kuramba kuchembera, zvinonyungudutsa hazvichinji tembiricha, munhu wese anozviziva;
3. Sezvo nzira yekubatanidza ndeyekupedza kushandiswa kwebhodhi rekudzivirira, pane zvinopesana, inoparadzawo kusungirirwa kwekubatanidza.Kana pane dambudziko nedambudziko iri munguva inotevera, kukanganisa kuchava kunouraya;
4. Hapana muenzaniso wekushandiswa kune dzimwe nyika.Neruzivo rwakakura rwemakemikari ekutanga kunze kwenyika, hazvigoneke kusawana ichi chinyorwa.
Redispersible latex poda
1. Chigadzirwa chelatex powder chinogadziriswa imvura inonyunguduka zvakare yakasvibiswa poda, iyo inonzi copolymer ye ethylene uye vinyl acetate, ine polyvinyl doro sekudzivirira colloid.
2. VAE redispersible latex powder ine firimu-forming properties, 50% aqueous solution inoumba emulsion, uye inoumba firimu rakafanana nepurasitiki mushure mekuiswa pagirazi kwemaawa makumi maviri nemana.
3. Iyo firimu yakaumbwa ine kumwe kushanduka uye kusagadzikana kwemvura.Inogona kusvika pachiyero chenyika.
3 uye kuvaka, ine yakasimba kuchinjika mu-anti-kutsemuka dhaka.
resin powder
1. Resin rabha poda rudzi rutsva rwechigadziriso chezvigadzirwa zvakaita serabha, resin, high molecular polymer, uye yakatsetseka yerabha poda;
2. Resin rubber powder ine general durability, kupfeka kusagadzikana, kusapararira kwakashata, vamwe vanonzwa flocculent (inofanira kunge ine porous material sepiolite), uye kune machena powders (asi ane kunhuhwirira kwakafanana 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, inoputika munguva pfupi.Kunyangwe kana isiri muzuva, iyo yekubatanidza interface ichaita Nekuda kwekuvakwa kwegomba, ichawora nekukurumidza;
5. Resin rubber powder haina kuumbwa, rega kushanduka.Zvinoenderana nemiyero yekuyedza yekunze madziro ekudzivirira dhaka, chete mwero wekukuvadza wepolystyrene board unosangana neyakajairwa.Zvimwe zviratidzo hazvisi kusvika pachiyero;
6. Resin rubber powder inogona kushandiswa chete kubatanidza polystyrene board, kwete vitrified beads uye mapuranga asingasviki moto.
