Kodi mungayese bwanji ufa wa polymer wosungunukanso wa RDP?

Njira yoyesera ya makhalidwe ndi kukhuthala kwa ufa wa polymer wosungunukanso, Padziko lonse lapansi amagwiritsidwa ntchito kwambiri kufalitsa ufa wa polymer RDP ndi ufa wa vinyl acetate ndi ethylene copolymerized emulsion, ethylene ndi vinyl chloride ndi lauric acid vinyl ester ternary copolymer powder, vinyl acetate ndi ethylene ndi senior fatty acid vinyl ester ternary copolymer powder, atatuwa kuti afalitse ufa wa polymer RDP pamsika wonse, makamaka vinyl acetate ndi ethylene copolymer powder VAC/E, ili ndi udindo waukulu padziko lonse lapansi ndipo imayimira ukadaulo wa ufa wa polymer wosungunukanso RDP.

Ufa wa polima wotha kusungunukansoRDP ili ndi mphamvu yolimba kwambiri yolumikizirana, imawonjezera kusinthasintha kwa matope ndipo imakhala ndi nthawi yayitali yotsegulira, imapatsa matope kukana kwabwino kwa alkaline, imawonjezera kukanikiza kwa matope, mphamvu yopindika, yosalowa madzi, yolimba, yokana kuvala komanso yomanga, ndipo mu matope osinthasintha otsutsana ndi ming'alu imakhala ndi kusinthasintha kwamphamvu.

Kuchokera pa zomwe zidachitika paukadaulo wa polima wosinthidwa ndi matope, ikadali njira yabwino kwambiri yaukadaulo:

1, RDP ndi imodzi mwa ma polima omwe amagwiritsidwa ntchito kwambiri padziko lonse lapansi.
2, Chidziwitso chachikulu chogwiritsa ntchito pa zomangamanga;

3, ikhoza kukwaniritsa zofunikira za matope a rheological (ndiko kuti, kapangidwe kofunikira);

4, ndi monomer ina polymer resin ili ndi zinthu zochepa zosasunthika (VOC) komanso mpweya woipa wochepa;

5, yokhala ndi kukana kwabwino kwa UV komanso kukana kutentha bwino komanso kukhazikika kwa nthawi yayitali;

6, yokhala ndi kukana kwakukulu kwa saponification;

7, yokhala ndi kutentha kwakukulu kwa galasi (Tg);

8, yokhala ndi mgwirizano wabwino kwambiri, kusinthasintha komanso mawonekedwe amakina;

9, magwiridwe antchito osavuta komanso ofanana a kuphatikiza koteteza kolloid (polyvinyl alcohol).

Njira yodziwira mphamvu ya zomatira za ufa wa polymer wosungunukanso wa RDP imadziwika ndi njira zotsatirazi zodziwira:

1, choyamba tengani ufa wa polima wosungunukanso wa RDP 5g mu kapu yoyezera galasi, onjezerani 10g ya madzi oyera ndikusakaniza kwa mphindi ziwiri, kuti usakanizike bwino;

2. Ikani chikho choyezera chosakaniza kwa mphindi zitatu ndikusakanizanso kwa mphindi ziwiri;

3. Pakani yankho lonse mu chikho choyezera pa mbale yopingasa yagalasi yoyera;

4, ikani mbale yagalasi mu bokosi loyesera la DW100 lokhala ndi kutentha kochepa;

5, potsiriza kuyikidwa mu 0°C nyengo yoyeserera zachilengedwe kwa ola limodzi, kuchotsa mbale yagalasi, kuyesa kuchuluka kwa kapangidwe ka filimu, malinga ndi kuchuluka kwa kapangidwe ka filimuyo komwe kamasintha ufa wa polymer wosungunukanso wa RDP pogwiritsa ntchito mphamvu yokhazikika yolumikizira.
