Txoj Kev Sealant

Raws li cov kev sib txawv hauv cheeb tsam ntawm kev siv, cov kev sib khi kev yog faib rau hom txias thiab qis, thiab kub thiab kub thiab kub thiab sov thiab kub thiab kub thiab kub thiab sov thiab kub thiab sov thiab kub thiab kub thiab kub thiab kub thiab sov thiab kub thiab sov thiab kub thiab kub thiab kub thiab sov thiab kub thiab sov thiab kub thiab kub thiab kub thiab kub thiab sov thiab kub thiab sov thiab kub thiab sov thiab kub thiab sov thiab kub thiab kub thiab kub thiab kub thiab sov thiab kub thiab kub thiab kub thiab sov thiab kub thiab sov thiab kub thiab kub thiab kub thiab kub thiab kub thiab txias thiab kub thiab sov thiab kub thiab sov thiab kub thiab kub thiab kub thiab kub thiab kub thiab kub thiab txias thiab kub hom. Raws li cov txheej txheem hauv tebchaws, cov kev sealadants tuaj yeem faib ua cov kub thiab txias, txias, txias, txias, txias, txias. Raws li cov qauv cua sov, txoj kev sealants tuaj yeem muab faib ua cov cua sov thiab tsis ncaj qha. Txoj kev seadants yaj sai sai, muaj zog adhesion, thiab nthuav tawm kev deformation zoo heev thiab rov qab zoo. Piv rau lwm hom kev sealants, sanaisi txoj kev sealant muaj cov viscosity qis dua thiab nkag tau yooj yim rau ntau qhov tawg. Ntawm qhov kub ntawm 180 ° C, cov roj txoj kev sealasav nkag mus thiab fuses nrog asphalt pavement. Thaum txias txias, nws txhim kho txoj kev sib raug zoo uas muaj zog thiab cia siab rau nws muaj zog elasticity, deforms elastically, deforms elastically expands raws li cov nras nthuav dav thiab ntawv cog lus, tswj hwm nws cov nyhuv seading.
