Nyob rau hauv xyoo tas los no, ntau resin polymer hmoov, muaj zog dej-resistant polymer hmoov thiab lwm yam pheej yig polymer hmoov tau tshwm sim nyob rau hauv lub lag luam los hloov cov tsoos VAE emulsion (vinyl acetate-ethylene copolymer), uas yog tshuaj tsuag-qhuav thiab ua los ntawm cov khoom siv rov ua dua tshiab polymer hmoov. Dispersed polymer hmoov, yog li dab tsi yog qhov txawv ntawm resin hmoov thiab redispersible polymer hmoov, resin hmoov hloov redispersible polymer hmoov? Mortar Technology Center yuav coj koj los txheeb xyuas qhov sib txawv ntawm ob qho tib si rau koj siv:
(1), redispersible polymer hmoov
Tam sim no, cov khoom siv hluav taws xob hloov pauv tau dav siv hauv ntiaj teb yog: yas acetate thiab ethylene copolymer hmoov (VAC / E), ethylene, vinyl chloride thiab vinyl laurate ternary copolymer hmoov (E / VC / VL), acetic acid Vinyl ester, ethylene thiab ntau dua fatty acid vinyl ester ternary copolymer hmoov (VAC/E/VeoVa), cov no peb redispersible polymer hmoov tuav tag nrho cov lag luam, tshwj xeeb tshaj yog vinyl acetate thiab ethylene copolymer hmoov VAC/EE, nyob rau hauv lub ntiaj teb no teb thiab sawv cev rau cov kev. Cov yam ntxwv ntawm redispersible polymer hmoov. Tseem yog qhov kev daws teeb meem zoo tshaj plaws nyob rau hauv cov nqe lus ntawm kev paub dhau los nrog cov polymers siv rau kev hloov kho mortar:
1. Nws yog ib qho ntawm cov polymers siv ntau tshaj plaws hauv ntiaj teb;
2. Daim ntawv thov kev paub hauv kev tsim kho yog qhov ntau tshaj;
3. Nws tuaj yeem ua tau raws li cov khoom siv rheological uas yuav tsum tau ua los ntawm mortar (uas yog, qhov tsim nyog yuav tsum tau ua);
4. Cov polymer resin nrog rau lwm cov monomers muaj cov yam ntxwv ntawm cov organic volatile teeb meem (VOC) thiab tsis tshua muaj irritating gas;
5. Nws muaj cov yam ntxwv ntawm kev ua haujlwm zoo UV, kev ua haujlwm kub zoo thiab kev ruaj ntseg ntev;
6. Kev ua haujlwm siab rau saponification;
7. Nws muaj qhov widest iav hloov kub ntau yam (Tg);
8. Nws muaj kev sib txuas zoo heev, kev ua haujlwm yooj yim thiab cov khoom siv tshuab;
9. Muaj kev paub ntev tshaj plaws hauv kev tsim tshuaj lom neeg ntawm yuav ua li cas tsim cov khoom zoo ruaj khov thiab kev paub txog kev tswj xyuas kev ruaj ntseg;
10. Nws yog ib qho yooj yim heev los ua ke nrog kev tiv thaiv colloid (polyvinyl cawv) nrog kev ua haujlwm siab.
(2), resin hmoov
Feem ntau ntawm cov "resin" polymer hmoov nyob rau hauv kev ua lag luam muaj cov tshuaj DBP. Koj tuaj yeem tshawb xyuas qhov teeb meem ntawm cov tshuaj no, uas cuam tshuam rau txiv neej kev ua haujlwm. Ib tug loj npaum li cas ntawm no polymer hmoov yog piled nyob rau hauv lub warehouse thiab nyob rau hauv lub laboratory, thiab nws muaj tej yam volatility. Nyob rau hauv lub lag luam Beijing, uas yog nto moo rau nws abundance ntawm "polymer hmoov", tam sim no muaj ib tug "polymer hmoov" soaked nyob rau hauv cov kuab tshuaj nrog ntau lub npe: high-strength dej-resistant polymer hmoov, resin polymer hmoov, thiab lwm yam nta:
1. Tsis zoo dispersibility, ib txhia xav tias ntub dej, ib txhia xav tias flocculent (nws yuav tsum yog cov khoom ntxeem tau zoo li sepiolite), ib txhia yog dawb thiab qhuav me ntsis tab sis tseem tsw tsw phem;
2. Nws tsw ntxhiab tsw heev;
3. Qee cov xim tau ntxiv, thiab cov xim tam sim no tshwm sim yog dawb, daj, grey, dub, liab, thiab lwm yam;
4. Qhov sib ntxiv yog me me, thiab qhov sib ntxiv rau ib tuj yog 5-12 kg;
5. Lub zog thaum ntxov yog qhov zoo heev. Cov cement tsis muaj zog nyob rau hauv peb hnub, thiab lub rwb thaiv tsev board tuaj yeem corroded thiab daig;
6. Nws tau hais tias XPS lub rooj tsavxwm tsis xav tau tus neeg sawv cev cuam tshuam.
Los ntawm cov qauv uas tau los txog tam sim no, nws tuaj yeem txiav txim siab tias nws yog cov kuab tshuaj raws li cov khoom siv absorbed los ntawm lub teeb ntxeem tau, tab sis tus neeg muag khoom xav txhob txwm zam lo lus "hloov", yog li nws hu ua "polymer hmoov".
tsis txaus:
1. Cov huab cua tsis kam ntawm cov kuab tshuaj yog qhov teeb meem loj. Nyob rau hauv lub hnub, nws yuav evaporate nyob rau hauv ib tug luv luv lub sij hawm. Txawm hais tias nws tsis nyob hauv lub hnub, qhov sib txuas sib txuas yuav decompose sai dua vim yog cov kab noj hniav;
2. Kev laus tsis kam, cov kuab tshuaj tsis yog qhov kub thiab txias, txhua tus paub qhov no;
3. Txij li thaum lub tshuab sib txuas yog kom yaj lub interface ntawm lub rwb thaiv tsev board, ntawm qhov tsis sib xws, nws kuj rhuav tshem cov kev sib txuas sib txuas. Yog tias muaj teeb meem nrog qhov teeb meem no nyob rau theem tom ntej, qhov cuam tshuam yuav ua rau tuag taus;
4. Tsis muaj qhov ua ntej ntawm daim ntawv thov nyob rau hauv txawv teb chaws. Nrog rau cov paub tab yooj yim tshuaj lom neeg txawv teb chaws, nws yog tsis yooj yim sua kom tsis pom cov khoom no.
Cov ntsiab lus:
Redispersible polymer hmoov:
1. Lub redispersible polymer hmoov khoom yog cov dej-soluble redispersible hmoov, uas yog ib tug copolymer ntawm ethylene thiab vinyl acetate, nrog polyvinyl cawv raws li ib tug tiv thaiv colloid.
2. VAE redispersible polymer hmoov muaj zaj duab xis-tsim cov khoom, 50% aqueous tov ua ib qho emulsion, thiab ua cov yas zoo li zaj duab xis tom qab muab tso rau hauv iav rau 24 teev.
3. Cov yeeb yaj kiab tsim muaj qee yam yooj yim thiab dej tsis kam. Nws tuaj yeem ncav cuag tus qauv hauv tebchaws.
4. Redispersible polymer hmoov muaj kev ua tau zoo: nws muaj peev xwm ua tau zoo, kev ua haujlwm zoo thiab kev ua haujlwm tsis zoo, kev sib txuas zoo zog, endows mortar nrog zoo alkali tsis kam, thiab tuaj yeem txhim kho qhov adhesion thiab flexural zog ntawm mortar Ntxiv nrog rau plasticity, hnav tsis kam. thiab kev tsim kho, nws muaj zog yoog raws hauv cov tshuaj tiv thaiv tawg.
Resin hmoov:
1. Resin polymer hmoov yog ib yam tshiab ntawm cov khoom hloov kho rau cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob siab molecular, thiab cov hmoov zoo hauv av polymer.
2. Resin polymer hmoov muaj cov kav ntev, hnav tsis kam, tsis zoo dispersion, qee qhov xav tias flocculent (nws yuav tsum yog cov khoom ntxeem tau zoo li sepiolite), thiab muaj cov hmoov dawb (tab sis muaj cov ntxhiab tsw zoo ib yam li roj av).
3. Ib co resin hmoov yog corrosive rau lub rooj tsavxwm, thiab waterproofing yog tsis zoo tagnrho.
4. Cov huab cua tsis kam thiab dej tsis kam ntawm resin polymer hmoov yog qis dua cov hmoov polymer. Huab cua tsis kam yog qhov teeb meem loj. Nyob rau hauv lub hnub, nws yuav evaporate nyob rau hauv ib tug luv luv lub sij hawm. Txawm hais tias nws tsis nyob hauv lub hnub, qhov sib txuas sib txuas yuav vim nws yog kab noj hniav, nws tseem yuav decompose sai dua.
5. Resin polymer hmoov tsis muaj moldability, cia nyob ib leeg yooj. Raws li cov qauv ntsuas rau sab nrauv phab ntsa rwb thaiv tsev mortar, tsuas yog qhov kev puas tsuaj ntawm polystyrene board ua tau raws li tus qauv. Lwm qhov ntsuas tsis tau raws li tus qauv.
6. Resin polymer hmoov tsuas yog siv tau rau kev sib koom ua ke polystyrene boards, thiab tsis tuaj yeem siv rau kev sib txuas cov hlaws vitrified thiab fireproof boards.
