PPG-Poly (propylene glycol)
Ibisobanuro
Uruhererekane rwa PPG rushongeshwa mu bintu bishongesha ibinyabuzima nka toluene, ethanol, na trichloroethylene. Rufite akamaro kanini mu nganda, ubuvuzi, imiti ikoreshwa buri munsi n'ibindi bikorwa.

Imikorere n'Imikoreshereze
1.PPG200, 400, na 600 bishongeshwa mu mazi kandi bifite imiterere nko gusiga amavuta, gushonga, gukuraho ibara, no kurwanya static. PPG-200 ishobora gukoreshwa nk'ikintu gitandukanya ibara.
2.Mu bijyanye no kwisiga, PPG400 ikoreshwa nk'amavuta yo kwisiga, yoroshya, n'amavuta yo kwisiga.
3. Ikoreshwa nk'ikintu gikuraho ibara mu marangi no mu mavuta ya hydraulic, nk'ikintu gikuraho ibara mu gutunganya latex y'ubukonje n'iy'ubushyuhe, nk'ikintu kirwanya ubukonje n'ubukonje mu mazi yo kohereza ubushyuhe, ndetse n'ikintu gihindura ubushyuhe.
4. Ikoreshwa nk'igikoresho cyo hagati mu gukora esterification, etherification, na polycondensation reactions.
5. Ikoreshwa nk'umusemburo wo gusohora, gushonga, n'inyongeramusaruro mu mavuta ya sintetike. Ikoreshwa kandi nk'inyongeramusaruro mu mazi ashongesha, amavuta ya roller, n'amavuta ya hydraulic, nk'amavuta yo kwisiga ashyushye cyane, ndetse nk'amavuta yo kwisiga imbere n'inyuma ya rubber.
6.PPG-2000~8000 ifite ubushobozi bwiza bwo gusiga amavuta, kurwanya ifuro, kurwanya ubushyuhe, no kurwanya ubukonje.
7.PPG-3000~8000 ikoreshwa cyane cyane nk'igice cya polyether polyols mu gukora plastiki za polyurethane foam.
8.PPG-3000 ~ 8000 ishobora gukoreshwa cyangwa igashyirwa mu buryo butaziguye mu gukora pulasitiki n'amavuta.
