Mavuto obwera chifukwa cha cellulose mukamagwiritsa ntchito putty powder

Ma cellulose amagwiritsidwa ntchito kwambiri pakupanga matope masterbatch, putty powder, asphalt road, gypsum products ndi mafakitale ena. Ili ndi mawonekedwe owongolera ndi kukhathamiritsa zida zomangira, ndikuwongolera kukhazikika kwapangidwe komanso kukwanira kwa zomangamanga. Lero, ndikudziwitsani mavuto omwe amayamba chifukwa cha cellulose mukamagwiritsa ntchito putty powder.

(1) Ufa wa putty ukasakanizidwa ndi madzi, ukakondolera kwambiri, umakhala wochepa thupi.

Ma cellulose amagwiritsidwa ntchito ngati thickener komanso kusunga madzi mu putty powder. Chifukwa cha thixotropy wa cellulose wokha, kuwonjezera kwa cellulose mu putty powder kumapangitsanso thixotropy pambuyo pa putty kusakanikirana ndi madzi. Mtundu uwu wa thixotropy umayamba chifukwa cha kuwonongeka kwa kapangidwe kake kosakanikirana kwa zigawo za putty powder. Zomangamanga zoterezi zimadzuka popuma ndikuwonongeka chifukwa cha kupsinjika maganizo.

(2) Putty imakhala yolemetsa panthawi yopukutira.

Izi nthawi zambiri zimachitika chifukwa kukhuthala kwa cellulose komwe kumagwiritsidwa ntchito ndikokwera kwambiri. Kuchulukitsa kowonjezera kwa khoma lamkati lamkati ndi 3-5kg, ndipo kukhuthala ndi 80,000-100,000.

(3) Kukhuthala kwa cellulose yokhala ndi kukhuthala komweko kumasiyana m'nyengo yozizira ndi chilimwe.

Chifukwa cha kutentha kwa cellulose, kukhuthala kwa putty ndi matope opangidwa kumachepa pang'onopang'ono ndi kuwonjezeka kwa kutentha. Pamene kutentha kumaposa kutentha kwa gel osakaniza a cellulose, cellulose imatuluka m'madzi, motero imataya kukhuthala. Ndibwino kuti musankhe mankhwala okhala ndi viscosity yapamwamba mukamagwiritsa ntchito mankhwalawa m'chilimwe, kapena kuwonjezera kuchuluka kwa cellulose, ndikusankha mankhwala omwe ali ndi kutentha kwa gel osakaniza. Yesani kugwiritsa ntchito methyl cellulose m'chilimwe. Pafupifupi madigiri 55, kutentha kumakhala kokwera pang'ono, ndipo kukhuthala kwake kudzakhudzidwa kwambiri.

Mwachidule, mapadi amagwiritsidwa ntchito mu ufa wa putty ndi mafakitale ena, omwe amatha kusintha madzimadzi, kuchepetsa kachulukidwe, kukhala ndi mpweya wabwino kwambiri, ndipo ndi wobiriwira komanso wokonda zachilengedwe. Ndi chisankho chabwino kwambiri choti tisankhe ndikuchigwiritsa ntchito.
