Kugwiritsiridwa ntchito kosiyanasiyana kwa zowonjezera zowonjezera za ufa wowuma!

1. Redispersible latex ufa

Zinthu zothirira pakamwa izi ndi polymer yapadera yama cell, yomwe imapangidwa kukhala ufa pambuyo poyanika kutsitsi.Pambuyo pokhudzana ndi madzi, ufa uwu ukhoza kukhala emulsion kachiwiri, ndipo uli ndi zofanana ndi emulsion.Madzi akamasanduka nthunzi, amatha kupanga filimu.Kanemayu ali ndi kusinthasintha kwakukulu, kukana kwanyengo, ndipo amawonetsa kumamatira kwambiri ku magawo osiyanasiyana.

Choncho, ndi zofunika zopangira mu matope youma wothira, amene akhoza kusintha ntchito, kuwonjezera mphamvu, kusintha adhesion wa ufa youma matope osiyanasiyana magawo, kusintha kusinthasintha, compressive mphamvu, ndi kuvala kukana youma ufa matope.Kuonjezera apo, ngati itasakanizidwa ndi hydrophobic latex powder, imatha kupanga matope owuma kuti asalowe madzi.

2. Ma cellulose

Ma cellulose okhala ndi ma viscosity osiyanasiyana ali ndi ntchito zosiyanasiyana.Ma cellulose amatha kugwiritsidwa ntchito mu ufa wocheperako pamakoma amkati, omwe amatha kukulitsa kusungika kwa madzi ndikuwonjezera kuchuluka.Ndiwokhazikika pamankhwala, imatha kuteteza mildew, imakhala ndi mphamvu yosunga madzi bwino, ndipo siyikhudzidwa ndi kusintha kwa pH.Itha kugwiritsidwa ntchito kuchokera ku 50,000 mpaka 200,000 viscosities.Mphamvu ya mgwirizano ndi inversely proportional, mamasukidwe akayendedwe ndi mkulu, koma mphamvu ndi yaing'ono, zambiri pakati 50,000 ndi 100,000.Ndikofunikira kwambiri kuonjezera kusanja ndi kukhazikika kwa dothi la ufa wowuma, komanso kuchepetsa kuchuluka kwa simenti.

Kuphatikiza apo, matope a simenti ali ndi nthawi yolimba.Pa nthawi yolimba, kukonza pamanja kumafunika kuti ikhale yonyowa.Chifukwa cha kusungirako madzi kwa cellulose, chinyontho chofunikira kuti chikhale cholimba cha matope chikhoza kupezeka kuchokera ku madzi osungiramo mapaipi, kotero kuti akhoza kukhazikika popanda kukonzanso mwapadera.

3. Lignin

Ntchito ya lignin mumatope owuma a ufa ndikukana kusweka.Lignin ikamwazikana m'madzi, imakhala ngati ulusi waufupi.Mwachitsanzo, pomanga makoma ndi dothi m'nyumba, udzu wa tirigu ndi udzu wa mpunga amawonjezedwa kuti asaphwanyike.Pogwiritsa ntchito lignin, ndi bwino kusankha zipangizo zoyera popanda zonyansa.Mukazindikira lignin, mutha kutembenuza lignin kuti muwone ngati pali fumbi lomwe latsala.Kuchuluka kwa ufa, kumakhala koyipa kwambiri.Kapena ikani lignin pang'ono m'madzi ndikuwona, kufalikira kwabwinoko, kumakhala bwinoko, zomwe zikutanthauza kuti ngati atawonjezeredwa kumatope owuma, ndizosavuta kumwazikana ndipo sizipanga mpira.

4. Inorganic chomangira zinthu

Phulusa la ufa wa calcium ndi calcium hydroxide, chinthu chomwe chimagwiritsidwa ntchito kwambiri pakupanga zinthu.Zimagwira ntchito yolumikizana ndi ufa wa putty kuti ukwaniritse zotsatira zosagwirizana ndi madzi komanso zosagwira madzi.Pali madera ambiri opangira miyala ya laimu ku China, kotero kupanga ufa wa laimu wa laimu ndikofala.Komabe, m'malo ena, matope a putty opangidwa ndi ufa wa laimu wa calcium amatha kutentha pakhungu la manja pomanga.Exothermic anachita, kotero kulemba phulusa kashiamu ufa kwambiri zamchere.Chojambulacho chikakula, chimakhala chosakhazikika, ndipo chimakhala chosavuta kusweka chikakanda pakhoma.Tikuyang'ana zakuthupi ndi phulusa lokhazikika la calcium ufa, lomwe lili ndi kalembedwe kakang'ono, kuyera bwino, ndipo sikuwononga manja.
