Hoʻolauna i ka Latex Powder

ʻO ka pauka latex redispersible he pauka keʻokeʻo keʻokeʻo, a ʻo ka mea nui i loko o ia mea:

1. Polymer resin: aia ma ke kumu o nā ʻāpana pauka lāʻau, ʻo ia ka mea nui o ka pauka latex redispersible, no ka laʻana, polyvinyl acetate/vinyl resin.

2. Nā mea hoʻohui (i loko): Me ka resin, hiki iā lākou ke hoʻololi i ka resin, e like me nā plasticizers e hoʻemi i ka mahana hana kiʻiʻoniʻoni o ka resin (ʻo ka maʻamau vinyl acetate / ethylene copolymer resins ʻaʻole pono e hoʻohui i nā plasticizers) ʻAʻole kēlā me kēia ʻano Rubber. Loaʻa nā mea hoʻohui i ka pauda.

3. Colloid pale: he papa o ka mea hydrophilic i wili ʻia ma ka ʻili o nā ʻāpana pauka latex redispersible, ʻo ka hapa nui o ka colloid pale o ka pauka latex redispersible he polyvinyl alcohol.

4. Nā mea hoʻohui (waho): Hoʻohui ʻia nā mea hou aku e hoʻonui i ka hana o ka pauka latex redispersible.No ka laʻana, hoʻohui ʻana i nā mea hoʻopuʻi superplasticizer i kekahi mau pauka lāʻau kōkua kahe, e like me nā mea hoʻohui i loko, ʻaʻole kēlā me kēia pauda latex redispersible i loko o ia mau mea hoʻohui.

5. Anti-caking agent: mea hoʻopiha mineral maikaʻi, hoʻohana nui ʻia e pale i ka caking o ka pauka lāʻau i ka wā o ka mālama ʻana a me ka lawe ʻana a hoʻomaʻamaʻa i ke kahe ʻana o ka pauka lāʻau (hoʻolei ʻia i waho o nā ʻeke pepa a i ʻole nā ​​kaʻa pahu).
