Redispersible polima ufa mu matope

Redispersible polima ufa nthawi zambiri amawoneka pomanga ngati zida zakunja zotchinjiriza khoma.Amapangidwa makamaka ndi tinthu tating'onoting'ono ta polystyrene ndi ufa wa polima, chifukwa chake amatchulidwa chifukwa chake.Mtundu uwu wa ufa wa polima umapangidwira makamaka tinthu tating'onoting'ono ta polystyrene.Mortar polima ufa uli ndi zomatira zabwino, zopangira mafilimu, kukana nyengo komanso kukhazikika kwamankhwala.

The ntchito zosiyanasiyana zamatopezobalalikansopolimaufaimatsimikiziranso kuti ntchito yake ndi yaikulu.Nthawi zambiri amagwiritsidwa ntchito popanga kutentha kwakunja kapena mkati kwa zophimba zakunja monga makoma akunja, matabwa a polystyrene, ndi matabwa otuluka.Chivundikiro cha ufa wamatope chikhoza kukhala ndi makhalidwe abwino kwambiri osalowa madzi, osawotcha moto komanso kuteteza kutentha.

Ndi masitepe otani pakupanga matope ndi ufa wa polima?Ndiloleni ndilankhule mwachidule za izi kuchokera ku mfundo zitatu:

1. Choyamba tiyenera kuyeretsa fumbi pakhoma kuti pakhale paukhondo ndi mwadongosolo;

2. Chiŵerengero cha kasinthidwe ndi motere → ufa wamatope: madzi = 1: 0.3, titha kugwiritsa ntchito chosakaniza chamatope kuti tizisakaniza mofanana posakaniza;

3. Titha kugwiritsa ntchito mfundo phala kapena woonda phala njira muiike pakhoma, kuti compress kuti flatness inayake;

Kuti mudziwe zambiri za zomangamanga, mutha kungoyang'ana:

1. Ndilo chithandizo choyambirira cha ufa wamatope.Tiyenera kuwonetsetsa kuti pamwamba pa bolodi lotsekera kuti tiyike ndi losalala komanso lolimba.Ngati ndi kotheka, amatha kupukutidwa ndi coarse sandpaper.Panthawi imeneyi, tisaiwale kuti kutchinjiriza bolodi ayenera mbamuikha mwamphamvu, ndi zotheka bolodi seams ayenera kusungunula ndi kutchinjiriza pamwamba ndi polima ufa polystyrene tinthu kutchinjiriza matope;

2. Tikakonza ufa wamatope, tiyenera kuwonjezera madzi mwachindunji, ndikuyambitsanso kwa mphindi 5 musanagwiritse ntchito;

3. Popanga ufa wamatope, tifunika kugwiritsa ntchito chitsulo chosapanga dzimbiri kuti tisungunuke matope odana ndi ming'alu pa bolodi lazitsulo, kanikizani nsalu ya galasi fiber mesh mumatope otentha a gypsum ndikupangitsa kuti ikhale yosalala.Nsalu ya mesh iyenera kulumikizidwa ndikuphatikizana mofanana.M'lifupi mwansalu yagalasi ya galasi ndi 10cm, nsalu ya galasi ya galasi iyenera kuyikidwa mkati mwake, ndipo makulidwe a fiber yowonjezeredwa pamwamba ndi pafupifupi 2 ~ 5cm.

Mortar polima ufa ndiye slurry womalizidwa mutawonjezera ufa wa polima.Kulimbana kwake ndi ming'alu kumakhala kolimba, komwe kungathe kuletsa kukokoloka kwa mpweya wa acidic pakhoma, ndipo sikophweka kupukuta ndi kuphwanyidwa ngakhale mutakhala wonyowa.Pazitsulo zina zamkati ndi kunja kwa khoma.
