Basa re redispersible latex poda mune zvigadzirwa zvedhaka

1. Ndeapi mabasa eredispersible latex powder mudhaka?

Mhinduro: Iro redispersible latex powder inoumbwa mushure mekupararira uye inoita sechipiri chekunamatira kusimbisa chisungo; iyo inodzivirira colloid inotorwa nedhaka system (haizonzi ichaparadzwa mushure mekuumbwa. Kana kuparadzirwa kaviri); yakaumbwa polymerization Iyo resin yemuviri inogoverwa mukati medhaka system sechinhu chinosimbisa, nekudaro ichiwedzera kubatanidzwa kwedhaka.

2. Ndeapi mabasa eredispersible latex powder mumatope emvura?

Mhinduro: Kuvandudza kushanda kwekuvaka; kunatsiridza fluidity; kuwedzera thixotropy uye sag resistance; kuvandudza kubatana; kuwedzera nguva yekuvhura; kuwedzera kuchengetwa kwemvura;

3. Ndeapi mabasa eredispersible latex powder mushure mekunge dhaka rapora?

Mhinduro: kuwedzera kusimba simba; kuwedzera simba rekukotama; kuderedza elastic modulus; kuwedzera deformability; kuwedzera kusimba kwezvinhu; kuwedzera kupfeka kusagadzikana; kuwedzera simba rakabatana; Iine yakanakisa hydrophobicity (inowedzera hydrophobic rubber poda).

4. Ndeapi mabasa eiyo redispersible latex poda mune dzakasiyana dzakaoma poda dhaka zvigadzirwa?
