Kugwiritsa Ntchito Ufa wa Polima Wosasinthika mu Mtondo Wodzaza Ma Joint

Ufa wa latex wosungunukanso wa polymerZopangidwazo ndi ufa wosungunuka m'madzi, womwe umagawidwa m'magulu awiri: ethylene/vinyl acetate copolymers, vinyl acetate/tertiary ethylene carbonate copolymers, acrylic acid copolymers, ndi zina zotero, ndi polyvinyl alcohol ngati colloid yoteteza. Chifukwa cha mphamvu yayikulu yomangirira komanso mawonekedwe apadera a ufa wa polymer wosungunuka.

Kuonjezera ufa wa polima womwazika ku matope odzaza mafundo kungathandize kuti ugwirizane bwino komanso kusinthasintha kwake.

Chomangira chomangira chiyenera kukhala chomangirira bwino ku maziko kuti chigwirizane ngakhale chitagwiritsidwa ntchito mochepa kwambiri. Chomangira chosasinthika cha simenti nthawi zambiri sichimalumikizana bwino popanda kukonza maziko pasadakhale.

Kuonjezera ufa wa latex wosungunuka kungathandize kuti ukhale wolimba. Kukana kwa saponification kwa ufa wa latex wosungunuka kungathe kuwongolera kuchuluka kwa kumamatira kwa matope mutakhudzana ndi madzi ndi chisanu. Polima wosungunuka akhoza kupezeka pogwiritsa ntchito copolymerizing vinyl acetate ndi ma monomers ena oyenera. . Kugwiritsa ntchito ethylene ngati comonomer yosasungunuka kupanga ufa wa latex wosungunuka wokhala ndi ethylene kungakwaniritse zofunikira zonse za ufa wa latex pankhani ya kukana kukalamba komanso kukana kwa hydrolysis.
