Redispersible latex ufandi kubalalitsidwa ufa akamagwira kutsitsi kuyanika wa kusinthidwa polima emulsion. Ili ndi dispersibility yabwino ndipo imatha kusinthidwanso kukhala emulsion yokhazikika ya polima pambuyo powonjezera madzi. Mankhwala ake amafanana ndendende ndi emulsion yoyamba. Choncho, Pofuna kuti zitheke kupanga matope apamwamba osakaniza owuma ndipo potero kupititsa patsogolo ntchito ya matope, lero tikambirana za ntchito ndi kugwiritsa ntchito ufa wa polima wopangidwanso.
Kodi ntchito za redispersible latex powder ndi ziti?
Redispersed polima ufa ndi chofunika kwambiri zinchito zowonjezera kwa matope osakaniza, amene angathe kusintha ntchito ya matope ndi matope kupititsa patsogolo mphamvu, kupititsa patsogolo mgwirizano mphamvu ya matope ndi magawo osiyanasiyana, kupititsa patsogolo matope katundu, compressive mphamvu kusinthasintha ndi deformability, flexural mphamvu, abrasion. kukana, kulimba, kumamatira ndi mphamvu yogwira madzi, ndi machinability. Kuphatikiza apo, ufa wa polima wokhala ndi hydrophobicity ukhoza kukhala ndi matope abwino osalowa madzi.
The redispersibility wa matope mu matope matope ndi pulasitala ndondomeko kumabweretsa lalabala ufa kukhala impermeability wabwino, posungira madzi, kukana chisanu, ndi mkulu kugwirizana mphamvu, amene angathe kuthetsa vuto la chikhalidwe Chinese zomangamanga matope ntchito zomangamanga zipinda. Mavuto omwe alipo kasamalidwe kabwino monga kung'amba ndi kulowa.
Mtondo wodziyimira pawokha, ufa wobalalitsidwanso wa latex wopangira zinthu zapansi, mphamvu yayikulu, mgwirizano wabwino / mgwirizano, ndipo umafunika kusinthasintha. Imawongolera kumamatira kwazinthu, kukana abrasion komanso kusunga madzi. Itha kubweretsa ma rheology abwino kwambiri, kuthekera kogwira ntchito komanso zinthu zabwino kwambiri zodzipusitsa kuti muchepetse matope odziyimira pawokha komanso matope owongolera.
Ufa wonyezimira wa latex wokhala ndi zomatira bwino, kusungirako madzi bwino, nthawi yayitali yotseguka, kusinthasintha, kukana kwa sag, komanso kukana kuzizira kwamadzi. Itha kukhala yocheperako yomatira matailosi, zomatira matailosi ndi njere za mpunga kuti zibweretse zomatira kwambiri, kukana kwambiri komanso ntchito yabwino yomanga.
Redispersible latex ufa wa matope a konkriti osalowa madzi amathandizira kulimba kwa zida zomangira magawo osiyanasiyana, amachepetsa kusinthasintha kwa mabizinesi, kumawonjezera kusungirako madzi, ndikuchepetsa kulowa kwamadzi. Zogulitsa zomwe zimapereka zisindikizo zokhala ndi hydrophobic komanso zofunikira zosagwiritsa ntchito madzi pakumanga dongosolo lokhalitsa.
Mtondo wakunja wakunja wotenthetsera matenthedwe amatha kubalalitsanso ufa wa latex mu dongosolo lakunja lotenthetsera matenthedwe, kukulitsa kulumikizana kwa matope ndi mphamvu yomangirira pa bolodi lotsekera matenthedwe, ndikuchepetsa kugwiritsa ntchito mphamvu kwinaku akukufunirani kutchinjiriza kwamafuta. The kunja khoma matenthedwe kutchinjiriza matope mankhwala amakwaniritsa ntchito yofunikira pa khoma lakunja , flexural mphamvu ndi kusinthasintha, kungachititse kuti matope anu katundu kukhala ndi makhalidwe abwino omangiriza ndi osiyanasiyana kutchinjiriza zipangizo ndi zigawo maziko, nthawi yomweyo, zimathandizanso kutchula kukana kwambiri komanso kukana kung'amba pamwamba.
Redispersible latex ufa wokonza matope ogwirizana ndi elasticity, shrinkage, adhesion high, flexural and tensile mphamvu zofunikira. Imakwaniritsa zofunikira zomwe zili pamwambazi pokonza matope kuti akonze konkire yomanga komanso yosagwirizana ndi zomangamanga.
The matope redispersible latex ufa kwa mawonekedwe makamaka ntchito pokonza deta ndi malo monga konkire, aerated konkire, laimu-mchenga njerwa ndi ntchentche njerwa phulusa. Sichapafupi kulumikiza, pulasitala wosanjikiza ndi dzenje, long'ambika, ndi peeled. Mphamvu yomatira imakulitsidwa, sikophweka kugwa ndi kukana madzi, ndipo kukana kuzizira kwachisanu kumakhala kwabwino kwambiri, komwe kumakhudza kwambiri njira yosavuta yogwirira ntchito komanso kasamalidwe koyenera kamangidwe.
Redispersible polima ufa ntchito
Zomatira matailosi, khoma lakunja ndi matope akunja opangira matenthedwe omangira matope, khoma lakunja lakunja lotenthetsera matope opaka matope, matailosi grout, matope a simenti oyenda okha, ma putty osinthika amkati ndi kunja kwa makoma, matope osunthika osakanikirana, mphira ufa wa polystyrene particle thermal. kutchinjiriza matope youma ufa wokutira.
Njira zopewera kugwiritsa ntchito redispersible latex powder:
The redispersible latex ufa siloyenera kulowetsa nthawi imodzi, ndipo m'pofunika kugawanitsa ndalamazo kuti mupeze ndalama zoyenera.
Pamene ulusi wa polypropylene uyenera kuwonjezeredwa, uyenera kumwazikana mu simenti poyamba, chifukwa tinthu tating'ono ta simenti timatha kuthetsa magetsi osasunthika a ulusi, kotero kuti ulusi wa polypropylene ukhoza kumwazikana.
Sakanizani ndi kusakaniza mofanana, koma nthawi yogwira ntchito isakhale yotalika kwambiri, mphindi 15 ndizoyenera, ndipo mchenga ndi simenti zimagwedezeka mosavuta ndikugwedezeka pamene zagwedezeka kwa nthawi yaitali.
M`pofunika kusintha mlingo wa zina ndi kuwonjezera yoyenera kuchuluka kwaMtengo wa HPMCmalinga ndi kusintha kwa nyengo
Pewani chinyezi chowonjezera zowonjezera kapena simenti.
Ndizoletsedwa kusakaniza ndikugwiritsa ntchito zinthu za acidic.
Ndikoletsedwa kugwiritsa ntchito pomanga pansi pa 5 ° C. Kumanga kwa kutentha kochepa kumayambitsa vuto lalikulu la khalidwe la polojekiti, zomwe zimapangitsa kuti matope opaka pulasitala asamamatire ndi bolodi. Ili ndi vuto lamtundu wa projekiti popanda dongosolo lokonzekera pambuyo pake
