Polyurethane
Polyurethane leak-cov khoom siv sealing feem ntau yog siv hauv cov haujlwm xws li kev txuag dej, kev tsim kho, thiab kav kav dej. Lawv cov khoom tseem ceeb yog isocyanates thiab polyols; cov tshuaj tiv thaiv ntawm lawv tso cai rau kev kho sai sai rau hauv cov qauv khoom. Lawv yog cov yam ntxwv los ntawm muaj zog adhesion, zoo heev dej tsis kam, thiab siab hardness.
Epoxy cob
Epoxy resin leak-cov khoom siv sealing yog tsim rau kev sib khi thiab kho qhov chaw ua los ntawm pob zeb, pob zeb, lossis hlau. Epoxy resins feem ntau yog tsim los ntawm epoxy pawg thiab amine pawg; Thaum sib xyaw, lawv hnov mob thiab kho kom tsim tau cov khoom siv nrog tshwj xeeb daim ntawv cog lus lub zog thiab tshuaj lom neeg ruaj khov. Tsis tas li ntawd, lawv muaj kev tiv thaiv zoo rau roj, acids, thiab alkalis.
Acrylate
Acrylate-raws li leak- cov khoom sib khi yog cov khoom siv polymeric feem ntau muaj cov monomers xws li methyl methacrylate thiab ethylene glycol methacrylate. Muaj peev xwm ntawm polymerization sai rau hauv cov khoom siv thaum raug huab cua, lawv muaj qhov zoo adhesion thiab hnav tsis kam, ua rau lawv siv dav hauv cov teb xws li kev tsim kho, choj engineering, thiab tunneling.
Cov khoom siv polymer
Polymer-raws li leak- cov khoom sib khi sawv cev rau chav kawm tshiab ntawm cov ntaub ntawv uas muaj qhov zoo xws li kev ua phooj ywg ib puag ncig thiab tiv thaiv dej thiab roj. Uas feem ntau ntawm cov resins, fibers, thiab muab tub lim, cov ntaub ntawv no tuaj yeem sib xyaw thiab siv ncaj qha mus rau qhov chaw ntawm cov yeeb nkab xau los kaw thiab kho qhov puas tsuaj.
