RDP kwa khoma putty

ZowonongekansoPolima ufa RDP/VAE, ndi wapadera emulsion kutsitsi kuyanika ufa wopangidwa ndi ethylene ndi vinilu acetate copolymer, chifukwa cha mkulu kugwirizana mphamvu ndi katundu wapadera, monga: kukana madzi, kumanga ndi kutentha kutchinjiriza, kotero, ali osiyanasiyana kwambiri ntchito.

udindo wanji pa RDPakhoza kusewera mukhoma putty?

1, kusintha zomatira ndi makina zimathakhoma putty. ZowonongekansoPolima ufa RDP/VAEpokhudzana ndi madzi amatha kumwazikana mwachangu mu emulsion, ndipo ali ndi zinthu zomwezo monga emulsion yoyamba, ndiko kuti, kutuluka kwa madzi kumatha kupanga filimu, filimuyi imakhala ndi kusinthasintha kwakukulu, kukana kwanyengo komanso kumamatira kwambiri kumadera osiyanasiyana.

2, kusintha mgwirizano wakhoma putty, kukana kwambiri kwa alkali, kukana kuvala, kuonjezera mphamvu yosinthasintha.

3, kusintha madzi kukana ndi permeability wakhoma putty.

4, kusintha madzi posungirakhoma putty, onjezani nthawi yotsegulira.

5, kusintha mphamvu kukana ndi kuonjezera durability wakhoma putty.

Koma kunja khomakhoma puttyziyenera kuwonjezeredwa mu kubalalitsidwa kwapolima ufa, akhoza kukhala mu kubalalitsidwa kwapolima ufapakhoma puttyali ndi kulimba kwabwino komanso mphamvu mochedwa, kupewa kupezeka kwa ufa mochedwa ndi mavuto ena.

Makasitomala nthawi zambiri amafunsa mafunso okhudzakhoma putty, mongakhoma puttyzosavuta kuvula ufa, ufa woopsa, kapena mphamvu ndizochepa ndi zina zotero. Onse amadziwakhoma puttymuyenera kuwonjezera cellulose ether, owerenga ambiri sawonjezera redispersiblepolima ufa. Chifukwa adzawonjezera mtengo wakhoma putty, kotero kuti mupulumutse mtengo, makasitomala ambiri samawonjezera, ndichifukwa chake putty ndi yosavuta ufa vuto lalikulu laubwino!

Ma celluloseetherimatha kuyamwa chinyezi ikawonjezedwa ndi madzi. Udindo waukulu wa cellulose ndikusunga madzi, koma pang'onopang'onoRDPufa pambuyo pa nthawi yayitali. Mtundu woterewu wa putty ndi wotayirira, mayamwidwe amadzi ndi okwera, ufa wosavuta, wopanda mphamvu, wopanda kukhuthala. Kuwongolera zovuta za putty pamwambapa zitha kusintha mawonekedwe a putty, kuwonjezera koyenera kwa ena obalalikapolima ufakupititsa patsogolo mphamvu yochedwa yakhoma putty.
