Nyob rau hauv xyoo tas los no, ntau resin roj hmab hmoov, high-strength dej-resistantredispersible polymer hmoovthiab lwm cov hmoov roj hmab pheej yig heev tau tshwm sim hauv khw los hloov cov tsoos VAE emulsion (vinyl acetate-ethylene copolymer), uas yog cov tshuaj tsuag qhuav thiab rov ua dua tshiab. Dispersible latex hmoov, ces dab tsi yog qhov txawv ntawm resin roj hmab hmoov thiab redispersible latex hmoov, resin roj hmab hmoov hloov redispersible latex hmoov?
1. Redispersible polymer hmoov RDP
Tam sim no, cov khoom siv dav siv dispersible polymer hmoov hauv ntiaj teb yog: yas acetate thiab ethylene copolymer roj hmab hmoov (VAC / E), ethylene thiab vinyl chloride thiab vinyl laurate terpolymer roj hmab hmoov (E / VC / VL), acetic acid Vinyl ester thiab ethylene thiab siab dua fatty acid vinyl ester terpolymer roj hmab hmoov (VAC/E/VeoVa), cov no peb dispersible polymer hmoov dominate tag nrho cov lag luam, tshwj xeeb tshaj yog yas acetate thiab ethylene copolymer roj hmab hmoov VAC/E/VeoVa E, muaj ib tug ua txoj hauj lwm nyob rau hauv lub ntiaj teb no. teb thiab sawv cev rau cov yam ntxwv ntawm dispersible 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. Muaj kev paub ntau tshaj plaws hauv kev tsim kho;
3. Nws tuaj yeem ua tau raws li cov khoom siv rheological uas yuav tsum tau ua los ntawm mortar (piv txwv li qhov yuav tsum tau ua haujlwm);
4. Lub polymer resin nrog rau lwm cov monomers muaj cov yam ntxwv ntawm cov organic volatile compounds (VOC) thiab tsis tshua muaj irritating gases;
5. Nws muaj cov yam ntxwv ntawm kev ua haujlwm zoo UV, kev ua haujlwm kub zoo thiab kev ruaj ntseg ntev;
6. Nws muaj siab saponification tsis kam;
7. Muaj qhov dav tshaj plaws iav hloov pauv kub ntau yam (Tg);
8. Nws muaj kev sib koom ua ke zoo, kev yooj yim thiab cov khoom siv kho tshuab;
9. Muaj kev paub ntev tshaj plaws hauv kev tsim tshuaj lom neeg ntawm kev tsim cov khoom lag luam ruaj khov thiab kev paub txog kev tswj xyuas kev ruaj ntseg;
10. Nws yog ib qho yooj yim los ua ke nrog kev tiv thaiv colloid (polyvinyl cawv) nrog kev ua haujlwm siab.
2. Resin hmoov
Feem ntau ntawm cov "resin" roj hmab hmoov ntawm lub khw 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 tus naj npawb ntawm cov hmoov roj hmab no tau muab tso rau hauv warehouses thiab lub chaw soj nstuam, thiab lawv yog volatile mus rau ib qho twg. Lub lag luam Beijing, uas yog nto moo rau nws cov khoom ntawm " roj hmab hmoov", tam sim no tau tshwm sim ib hom " roj hmab hmoov" soaked nyob rau hauv cov kuab tshuaj nrog ntau lub npe: high-strength dej-resistant nplaum hmoov, resin nplaum hmoov, thiab lwm yam. :
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), thiab ib txhia yog dawb thiab qhuav me ntsis tab sis tseem tsw ntxhiab;
2. ntxhiab tsw heev;
3. Qee cov xim tau ntxiv, thiab cov xim tam sim no yog xim dawb, daj, grey, dub, liab, thiab lwm yam;
4. Cov nyiaj ntxiv yog tsawg heev, thiab qhov ntxiv rau ib tuj yog 5 ~ 12 kg;
5. Lub zog thaum ntxov yog amazing. Cov cement tsis muaj zog rau peb hnub, thiab nws tuaj yeem corrode lub rwb thaiv tsev board thiab lo rau nws.
6. Nws tau hais tias XPS pawg thawj coj tuaj yeem siv yam tsis muaj 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 los ntawm cov khoom siv ntxeem tau, tab sis tus neeg muag khoom xav kom zam lo lus "hloov" txhob txwm tshaj tawm, yog li nws hu ua "cov hmoov roj hmab"
tsis txaus:
1. Cov huab cua tsis kam ntawm cov kuab tshuaj yog qhov teeb meem loj. Nyob rau hauv lub hnub, nws yuav volatilize nyob rau hauv ib lub sij hawm luv luv. Txawm hais tias nws tsis nyob hauv lub hnub, qhov sib txuas sib txuas yuav decompose sai dua vim yog kab noj hniav;
2. Kev laus tsis kam, hnyav hnyav tsis kub resistant, 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 nyob rau theem tom ntej, qhov cuam tshuam yuav ua rau tuag taus;
4. Tsis muaj qhov ua ntej rau kev thov txawv teb chaws. Nrog rau kev paub dhau los ntawm kev lag luam tshuaj lom neeg txawv teb chaws, nws tsis tuaj yeem nrhiav pom cov khoom no.
Cov ntsiab lus:
Muaj nyob rau hauv dispersible latex hmoov:
1. Cov khoom siv redispersible latex hmoov yog cov dej-soluble redispersible hmoov, uas yog copolymer ntawm ethylene thiab vinyl acetate, thiab siv polyvinyl cawv ua ib qho kev tiv thaiv colloid.
2. VAE redispersible latex hmoov muaj zaj duab xis-tsim cov khoom, 50% aqueous tov ua ib qho emulsion, thiab nws ua ib zaj duab xis zoo li yas 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. Muaj peev xwm ncav cuag lub teb chaws tus qauv.
4. Lub redispersible latex hmoov muaj kev ua tau zoo: nws muaj peev xwm sib txuas siab, kev ua tau zoo thiab kev ua haujlwm tsis zoo, kev sib txuas zoo zog, ua rau cov mortar nrog zoo alkali tsis kam, thiab tuaj yeem txhim kho cov nplaum thiab flexural zog ntawm cov mortar. , plasticity, hnav tsis kam thiab kev tsim kho, nws muaj zog yoog raws hauv cov tshuaj tiv thaiv tawg.
Resin hmoov:
1. Resin roj hmab hmoov yog ib yam tshiab ntawm kev hloov kho rau roj hmab, resin, macromolecular polymer, av roj hmab hmoov thiab lwm yam khoom.
2. Resin roj hmab hmoov muaj cov khoom siv dav dav, kev ua haujlwm tsis zoo, tsis zoo dispersibility, qee qhov xav tias flocculent (nws yuav tsum yog cov khoom ntxeem tau zoo li sepiolite), thiab cov hmoov dawb (tab sis muaj 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 roj hmab hmoov yog qis dua cov hmoov latex. Huab cua tsis kam yog qhov teeb meem loj. Nyob rau hauv lub hnub, nws yuav volatilize nyob rau hauv ib lub sij hawm luv luv. Txawm hais tias nws tsis nyob hauv lub hnub, qhov sib txuas sib txuas, Txij li nws yog kab noj hniav, nws tseem yuav decompose sai dua.
5. Resin roj hmab hmoov tsis muaj moldability, los yog yooj. Raws li kev soj ntsuam tus qauv ntawm cov khoom siv hluav taws xob sab nraud rau cov phab ntsa sab nrauv, 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 kua nplaum hmoov tsuas yog siv tau rau kev sib koom ua ke ntawm polystyrene boards, tsis yog rau kev sib txuas ntawm cov hlaws dai vitrified thiab fireproof boards.
