Acrylic thiab silicone yog cov feem ntau siv sealants. Txawm hais tias lawv muaj ntau qhov sib xws, lawv txawv ntawm txoj hauv kev tseem ceeb. Vim li no thiaj muaj kev siv sib txawv.
Sealants
Sealants yog siv los ntawm cov kws tshaj lij thiab cov neeg ua haujlwm nyiam ua haujlwm rau ntau lub hom phiaj. Feem ntau, qhov no ib txwm suav nrog kev ua haujlwm xws li backfilling lossis sealing. Qhov no kuj tseem siv tau rau acrylic thiab silicone. Feem ntau, sealants feem ntau siv tau rau cov haujlwm hauv qab no:
- Txhua yam pob qij txha
- Filling qhov thiab tawg
- Laminating thiab sealing cov ntsiab lus sib txuas
- Repairing and compensating for subsurface defects
- Gluing light parts
Note:
Xyaum tag nrho cov sealants kuj muaj cov nplaum ua haujlwm. Txawm li cas los xij, qhov no qis dua nrog cov nplaum sib dhos, piv txwv li.
Acrylic thiab silicone compounds feem ntau yog siv thaum kho thiab kho qhov chaw. Tej thaj chaw ntawm daim ntawv thov yog chav dej, chav dej thiab chav ua noj. Tom qab ntawd lawv coj cov haujlwm uas tau ua dhau los ntawm Kitt. Qhov no kuj txhais tau hais tias ob qho khoom siv kuj tseem siv tau thaum txhim kho lub qhov rais pane.
Zoo thiab sib txawv
Acrylic thiab silicone muaj roughly tib yam sib xws ua ntej ua. Qhov no yog porous loj. Txawm li cas los xij, silicone twb zoo li roj hmab hauv lub xeev no, thaum acrylic yog ntau reminiscent ntawm putty.
Tip:
Yog tias nws tsis paub meej tias qhov twg sealant koj tab tom soj ntsuam, kev kuaj tsis hnov tsw tuaj yeem pab tau. Silicone muab cov ntxhiab tsw me ntsis ntawm vinegar.
Ob yam khoom tsis txawv ntau ntawm kev ua ib yam. Txwv tsis pub, muaj qhov sib txawv loj heev, uas tom qab ntawd ua rau kev siv sib txawv. Tsis zoo li acrylic, silicone tsis yog dej-soluble thiab yog li tsis muaj dej. Silicone tsis tuaj yeem pleev xim rau thiab tsis daj. Acrylic, ntawm qhov tod tes, tuaj yeem pleev xim rau, tab sis nws tuaj yeem daj. Silicone kuj tseem ncab heev thiab muaj lub sijhawm ziab ntev dua. Acrylic, ntawm qhov tod tes, tsis tuaj yeem ncav cuag, tab sis dries sai sai.
Applications
Raws li twb tau hais lawm, qhov sib txawv ntawm cov khoom siv hauv tsev ua rau muaj kev siv sib txawv.
Silicon
Vim nws cov dej permeability, silicone yog tshwj xeeb tshaj yog haum thaum nws los txog rau sealing ib yam dab tsi. Qhov no feem ntau tsim nyog hauv chav ua noj thiab chav dej. Txij li cov khoom siv kuj yog weatherproof, nws kuj siv tau sab nraum zoov nrog cov txheeb ze yooj yim. Feem ntau silicone yog siv rau kev ua haujlwm hauv qab no:
- Kev sib khi lub dab dej, qhov cub thiab chav ua haujlwm hauv chav ua noj
- Cia da dej, da dej thiab dab dej hauv chav dej
- Cov pob qij txha uas raug rau qhov kub thiab txias hloov pauv ntau
Acrylic
Acrylic sealants, ntawm qhov tod tes, yog feem ntau haum rau siv nyob rau hauv qhuav tej yam kev mob. Tej thaj chaw ntawm daim ntawv thov yog:
- Filling kab nrib pleb hauv plaster lossis masonry
- Compensating defects in the masonry or ceiling
- Smoothing ntxhib, tsis sib xws
