Mumakore achangopfuura, yakawanda resin polymer hupfu, yakakwirira-simba-inodzivirira mvura yepolymer upfu uye humwe hupfu hwakachipa hwepolymer hwakaonekwa pamusika kutsiva yechinyakare VAE emulsion (vinyl acetate-ethylene copolymer), iyo yakapfapfaidzwa-yakaomeswa uye. yakagadzirwa nehupfu hwepolymer hunogona kushandiswa zvakare.Yakaparadzirwa polima poda, saka ndeupi musiyano uripo pakati pehupfu hweresin uye hupfu hwepolymer hunogona kudzoreredzwa, hupfu hunogona kutsiva hupfu hwepolymer hunogona kutsiva?Mortar Technology Center inotungamira iwe kuti uongorore muchidimbu musiyano uripo pakati pezviviri zvereferensi yako:
(1), redispersible polymer hupfu
Parizvino, iyo redispersible polymer hupfu hunoshandiswa zvakanyanya munyika ndeiyi: vinyl acetate uye ethylene copolymer hupfu (VAC/E), ethylene, vinyl chloride uye vinyl laurate ternary copolymer hupfu (E/VC/VL), acetic acid Vinyl ester, ethylene. uye yakakwira fatty acid vinyl ester ternary copolymer powder (VAC/E/VeoVa), aya matatu anodispersible polymer hupfu anotonga musika wese, kunyanya vinyl acetate uye ethylene copolymer poda VAC/EE, inobata chinzvimbo chinotungamira mundima yepasi 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.
(2), resin powder
Mazhinji e "resin" polymer poda pamusika ine makemikari chinhu DBP.Iwe unogona kutarisa kukuvadza kwechinhu ichi chemakemikari, chinokanganisa basa revarume pabonde.Huwandu hukuru hwemhando iyi yepolymer poda inotutira mudura uye murabhoritari, uye ine kumwe kushanduka.Mumusika weBeijing, uyo unozivikanwa nekuwanda kwe "polymer powder", pave ne "polymer powder" yakanyikwa muzvinonyungudutsa zvine mazita akasiyana-siyana: yakakwirira-simba inodzivirira mvura yepolymer powder, resin polymer powder, etc.
1. Murombo dispersibility, vamwe vanonzwa kunyorova, vamwe vanonzwa flocculent (inofanira kunge ine porous zvinhu sepiolite), 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. Kuwanda kwekuwedzera kuduku zvikuru, uye chiyero chekuwedzera kwetani imwe 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 weiyo interface.
Kuburikidza nemienzaniso yakawanikwa kusvika ikozvino, inogona kugumiswa kuti i-solvent-based resin yakashambadzirwa nechiedza chine porous zvinhu, asi mutengesi anoda kudzivisa nemaune shoko rokuti "solvent", saka inonzi "polymer 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.
pfupiso:
Redispersible polymer poda:
1. Chigadzirwa chepolymer powder chinogadziriswa imvura inonyunguduka zvakare, iyo inonzi copolymer ye ethylene uye vinyl acetate, ine polyvinyl doro sekudzivirira colloid.
2. VAE redispersible polymer 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.
5 uye kuvaka, ine yakasimba kuchinjika mu-anti-kutsemuka dhaka.
Resin powder:
1. Resin polima polima rudzi rutsva rwechigadzirwa chinogadziridza chepolymer, resin, high molecular polymer, uye yakatsetseka yepolymer powder.
2. Resin polymer 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 kushorwa kwemvura kwe resin polymer powder zvakaderera pane zvepolymer powder.Kuramba kwemamiriro ekunze idambudziko guru.Muzuva, inoputika munguva pfupi.Kunyangwe kana isiri muzuva, iyo yekubatanidza interface ichaita Nekuti iri kuvakwa kwegomba, inowora nekukurumidza.
5. Resin polymer 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 polymer poda inogona kungoshandiswa pakubatanidza mapuranga epolystyrene, uye haigoni kushandiswa pakubatanidza mabheji ane vitrified uye mapuranga asingasviki moto.
