Thaum nws los txog rau cov ntaub ntawv sealing, muaj peb lub ntsiab ntawm cov sealants feem ntau siv hauv ntau daim ntawv thov:polyurethane, silicone, thiabdej-raws li latex. Txhua yam ntawm cov sealants no muaj cov khoom tshwj xeeb thiab tsim nyog rau kev siv sib txawv. Kev nkag siab txog cov khoom ntawm cov sealants no tseem ceeb heev rau kev xaiv cov sealant tsim nyog rau ib qhov project tshwj xeeb.
Polyurethane sealantspaub txog lawv qhov tshwj xeeb durability thiab yooj. Lawv feem ntau yog siv rau hauv kev tsim kho thiab kev siv hauv kev lag luam uas yuav tsum tau muaj kev sib khi ruaj khov thiab kav ntev. Polyurethane sealants yog huab cua-, tshuaj-, thiab puas-resistant, ua rau lawv zoo tagnrho rau siv sab nraum zoov. Lawv kuj muaj peev xwm ua raws li ntau yam khoom siv, xws li pob zeb, ntoo, hlau thiab yas. Tsis tas li ntawd, polyurethane sealants muaj kev tiv thaiv zoo rau UV hluav taws xob thiab tsim nyog rau kev sib khi cov pob qij txha thiab qhov khoob hauv cov qauv sab nraum zoov.
Silicone sealantsyog nrov rau lawv zoo heev adhesion thiab yooj. Lawv feem ntau yog siv rau hauv cov kav dej, tsheb thiab hluav taws xob siv vim lawv tsis kam mus ya raws thiab huab cua kub. Silicone sealants tseem paub txog lawv lub peev xwm nyob twj ywm nyob rau hauv ntau qhov kub thiab txias, ua rau lawv haum rau siv sab hauv tsev thiab sab nraum zoov. Lawv kuj tseem tiv taus pwm thiab pwm kev loj hlob, ua rau lawv zoo tagnrho rau kev sib khi cov pob qij txha hauv qhov chaw ntub dej xws li chav dej thiab chav ua noj. Tsis tas li ntawd, silicone sealants muaj cov khoom siv hluav taws xob zoo, ua rau lawv tsim nyog rau kev sib khi cov khoom siv hluav taws xob thiab kev sib txuas.
Water-based latex sealantspaub txog lawv qhov yooj yim ntawm daim ntawv thov thiab paintability. Lawv feem ntau siv rau hauv cov ntawv thov sab hauv xws li kev sib khi qhov khoob thiab cov kab nrib pleb hauv cov phab ntsa, qhov rais thiab qhov rooj. Water-based latex sealants yog ib qho yooj yim los ntxuav nrog dej thiab tsis muaj ntxhiab tsw, ua rau lawv haum rau siv sab hauv tsev. Lawv kuj tuaj yeem pleev xim rau kev sib txuas seamlessly nrog ib puag ncig. Thaum cov dej-raws li latex sealants tej zaum yuav tsis zoo li polyurethane los yog silicone sealants, lawv yog ib qho kev xaiv zoo heev rau sab hauv sealing tej yaam num uas yooj yim ntawm kev siv thiab zoo nkauj tseem ceeb.
Hauv cov ntsiab lus, polyurethane, silicone, thiab dej-raws li latex sealants txhua tus muaj cov khoom tshwj xeeb thiab tsim nyog rau kev siv sib txawv. Polyurethane sealants paub txog lawv cov kav ntev thiab huab cua tsis kam, ua rau lawv zoo tagnrho rau kev siv sab nraum zoov. Silicone sealants muaj nuj nqis rau lawv qhov yooj yim thiab ua haujlwm rau cov dej noo thiab huab cua kub, ua rau lawv haum rau ntau yam kev siv. Water-based latex sealants yog ib qho yooj yim mus thov, pleev xim rau thiab tsis muaj ntxhiab tsw, ua rau lawv zoo tagnrho rau sab hauv sealing tej yaam num. Kev nkag siab txog cov khoom ntawm cov sealants no tseem ceeb heev rau kev xaiv cov sealant tsim nyog rau ib qhov project tshwj xeeb.
