Zotsatira za Mlingo wa RDP pa Mphamvu Yogwirizira ndi Kuletsa Madzi

Phatikizani ndi zinthu zofunika kwambiri pantchito zokongoletsera zokongoletsera, ndipo khalidwe lake limakhudza mwachindunji moyo wa ntchito ndi zokongoletsera kukhoma. Kugwiritsa ntchito mphamvu ndi kukana kwamadzi ndichizindikiro chofunikira pakuwunikira magwiridwe antchito.Kubwezeretsedwanso, ngati gawo losinthika la polymer losinthidwa, limachita mbali yofunika kwambiri pakuwongolera magwiridwe antchito.

1. Makina ogwiritsira ntchito obwezeredwa

Ufa wokwezedwa ndi ufa ndi ufa wopangidwa ndi kupukuta kwa polima emulsion. Itha kukonzanso kuti apange dongosolo lokhazikika la polima mutalumikizana ndi madzi, omwe amathandizira kukulitsa mphamvu ndi kusinthasintha kwamphamvu. Ntchito zake zazikulu zikuphatikiza:

Kuwongolera Mphamvu Yogwirizanitsa: Kukwezedwa ufa wa latx kumapanga kanema wa polymer nthawi yowuma, komanso ma synergrazizs okhala ndi zida zophatikizira kuti zitheke luso lokhathamiritsa.

Kulimbitsa Madzi Kukaniza: Masamba a latex amapanga ma network a hydrophobic mu putty kapangidwe, kuchepetsa kulowa kwamadzi ndikuwongolera kusintha madzi.

Kuwongolera kusinthika: Kutha kuchepetsa kutsekemera kwa Detty, kusintha kuthekera, ndikuchepetsa chiopsezo cha ming'alu.

2. Phunziro loyesera

Zipangizo Zoyeserera

Zinthu Zoyambira: Ufa wa Simentazi

Kubwezeretsedwanso ufa wa Mayx: Ethylene-vinyl acetate (Eva) Coptolymer FATX ufa

Zina zowonjezera: Thickener, wogulitsa madzi osunga, filler, etc.

Njira Yoyesera

Makina osokoneza bongo osinthika a Masamba (0%, 2%, 5%, 8%, 10%) adakonzedwa motero, ndipo kugwirizanitsa kwawo mphamvu ndi kukana madzi zidayesedwa. Mphamvu yolumikizana idatsimikizika ndi kuyesa kwa kukoka, ndipo mayeso ogwirizanitsa madzi adayesedwa ndi mphamvu zosunga mphamvu pambuyo pomiza m'madzi kwa maola 24.

3. Zotsatira ndi zokambirana

Zotsatira za ufa waposachedwa pa ufa wolumikizana

Zotsatira zoyesedwa zikuwonetsa kuti ndi kuchuluka kwa kuchuluka kwa mlingo wa RPP, kulimba kwa mafuta kuwonetsa kumawonetsa momwe zimapangidwira koyamba ndikukhazikitsa.

Mlingo wa RDP ikawonjezeka kuchokera pa 0% mpaka 5%, kulimba mtima kwamphamvu kumasintha kwambiri, chifukwa filimu ya polymer yopangidwa ndi rdp imawonjezera mphamvu yolumikizana pakati pa maziko apansi pa maziko ake.

Pitilizani kuwonjezera rdp mpaka 8%, kukula kwa mphamvu yolumikizira kumakhala kwathyathyathya, ndipo ngakhale pang'ono kumachepetsa 10%, komwe kungakhale chifukwa RDP yochulukirapo idzasokoneza mawonekedwe okhazikika ndikuchepetsa mphamvu.

Zotsatira za ufa waposachedwa pa ufa wa madzi

Zotsatira zoyeserera zamadzi zikuwonetsa kuti kuchuluka kwa RDP kumakhudzanso madzi kukana.

Mphamvu yogwiririra yopanda pake yopanda madzi yopanda madzi idawonongeka kwambiri atanyowa m'madzi, kuwonetsa madzi osanja.

Kuphatikiza kwa kuchuluka koyenera (5% -8%) kumapangitsa kuti pakhale mawonekedwe a organic-inchic, amasintha madzi, ndikusintha kosunga mphamvu, ndikuwongolera mphamvu ya kumizidwa maola 24.

Komabe, pamene RDP ikapitilira 8%, kusintha kwa madzi kukana kumadzi kumachepa, komwe kungakhale chifukwa zinthu zokulirapo zolimba zimachepetsa luso la anti-hydrolysis a purty.

Mapeto ake otsatirawa angakopeka ndi kafukufuku woyeserera:

Kuchuluka koyeneraKubwezeretsedwanso(5% -8%) imatha kukonza kwambiri mphamvu ndi madzi kukana.

Kugwiritsa ntchito kwambiri RDP (> 8%) kungakhudze kapangidwe kake kake, zomwe zimapangitsa kuchepa kapena kuchepa kwambiri pakusintha kwa mphamvu ndi kukana madzi.

Mlingo woyenera woyenera umafunikira kukhazikika molingana ndi plagenario yofunsira kuti mukwaniritse bwino kwambiri pakati pa magwiridwe antchito ndi mtengo.
