Sealant yog cov qhua zoo sib xws hauv tes ntawm cov kav dej thiab cov chaw da dej tshwj xeeb. Nws ua haujlwm zoo heev ntawm kev sib khi seams, qee yam kab nrib pleb lossis pob qij txha, yog li tiv thaiv thaj chaw kho los ntawm noo noo. Dej, nkag mus rau hauv cov qhov no, txhawb txoj kev loj hlob ntawm cov kab mob microscopic thiab fungi, thiab lawv, tig, rhuav tshem txhua yam uas lawv ntsib.
Peb yuav sim xyuas seb lub hnab ntim dej dab tsi zoo dua, hom twg tuaj yeem pom hauv khw thiab dab tsi yuav tsum tau them tshwj xeeb rau thaum yuav. Cia peb xav txog cov kev xav ntawm cov kws tshaj lij hauv daim teb no thiab cov kev tshuaj xyuas ntawm cov neeg siv tib yam.
Tim cov sealants
Ua ntej txiav txim siab seb lub chav da dej twg yog qhov zoo tshaj plaws, cia peb xub saib nws cov muaj pes tsawg leeg thiab hom tseem ceeb. Nws lub hauv paus, feem ntau, yog polymers, fillers, hardeners thiab dyes.
Nyob ntawm qhov feem pua ntawm cov khoom no thiab cov khoom siv polymer, cov hom muaj pes tsawg leeg sib txawv. Yog tias koj tsis nkag mus rau hauv cov tshuaj tua kab mob, tag nrho muaj plaub yam tseem ceeb ntawm chav dej sealant.
YSilicon
Nov yog ib hom kev thov tshaj plaws, tab sistib lub sij hawm kim tshaj plaws. Cov kws tshaj lij hauv daim teb no xav txog silicone da dej sealant yog qhov zoo tshaj plaws ntawm lwm tus. Nws yog tsim rau txhua txheej: cam khwb cia hlau, hlau thiab niaj hnub - acrylic.

Silicone chav dej sealants, nyob rau hauv lem, muab faib ua ob subspecies - acidic (acetic) thiab nruab nrab. Cov qub yog txawv los ntawm lawv cov nqi qis, cov yam ntxwv tsw thiab fastidiousness rau qhov chaw uas lawv tau thov. Cov tshuaj tiv thaiv ntawm cov kua qaub sealant tuaj yeem kho, oxidizing qee cov hlau thiab hlau.
Lub ntsiab lus tseem ceeb ntawm cov khoom sib xyaw yog ceramics, yas thiab ntoo. Yog li ntawd, acidic silicone sealant rau acrylic da dej yog twv yuav raug hu tsis haum, thiab nws tsis pom zoo kom siv nws rau lwm yam txheej.
Hauv ib nrab ntawm cov xwm txheej zoo, cov kws tshaj lij qhia ua haujlwm nrog qhov nruab nrab muaj pes tsawg leeg. Nws mus zoo nrog txhua hom txheej txheej, thiab kev sib khi ntawm seams, pob qij txha thiab cov kab nrib pleb tsis ua rau muaj kev cuam tshuam cov tshuaj lom neeg, xws li tib lub vulcanization. Li no, qhov tseeb, lub npe - nruab nrab. Xws li cov khoom siv hauv chav dej yog qhov kim dua, yog li ceev faj thiab tsis txhob yuam kev yuav cov kua qaub thaum sim txuag nyiaj.
Acrylic
hom sealant no xyaum tsis zoo dua li yav dhau los hais txog kev pabcuam lub neej thiab tseem muaj adhesion zoo ntawm cov txheej txheem.

Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm qhov kev sib xyaw no yog kev tsis txaus ntseeg rau cov txheej txheem tom ntej. Acrylic sealant tuaj yeem siv tau zoo nrog cov kua roj vanish, pleev xim, lossis zoo tsw nrog plaster. Qhov tsuas yog qhov tsim nyog qhia meej yog tias qee zaum hauv khw muag khoom lawv ntsib cov khoom sib xyaw uas tsis tiv taus noo noo. Lawv tau siv rau qee qhov kev xav tau tshwj xeeb, tab sis yeej tsis yog rau lub dab da dej thiab chav dej, yog li nco ntsoov ua tib zoo saib xyuas cov ntawv sau npe.
YPolyurethane
Qhov no yog ib qho muaj zog, siv tau zoo thiab hnyav tshuaj hauv chav dej sealant. Nws raug nqi ntau dua li silicone counterpart, tab sis nws muaj nws tus kheej undeniable pluses thiab minuses. Cov qub suav nrog kev ua haujlwm zoo heev rau kev puas tsuaj thiab kev ua kom zoo heev.
Ntau zaus, tsis txhob tshem cov sealant los ntawm lub dab da dej, ib qho polyurethane compound tsuas yog siv rau saum nws. Cov txheej txheem no feem ntau yog ua nrogqub silicone sutures. Tom qab ntawd txhua cov khoom siv kho kom zoo nkauj lossis cov txheej txheem npaj yog siv rau saum, xws li cov kua roj vanish lossis xim.
Raws li tau hais los saum toj no, cov khoom siv polyurethane tau ntim rau hauv lub peev xwm nrog cov ntsiab lus txaus ntshai, yog li koj yuav tsum ua haujlwm nrog nws nrog ceev faj, siv hnab looj tes thiab lub npog ntsej muag.
YSilicon Acrylic
Raws li lub npe txhais tau tias, qhov no yog ib hom hybrid uas suav nrog cov yam ntxwv zoo tshaj plaws ntawm ob hom. Ntawm no peb muaj ib tug muaj zog muaj pes tsawg leeg thiab ib tug ntev kev pab cuam lub neej. Vim nws txoj kev ua tau zoo, cov khoom sib txuas sib txuas no tuaj yeem siv dawb los siv rau daim ntawv cog lus, piv txwv li ua cov nplaum.
Yog tias koj tsis ntseeg thiab tsis tuaj yeem xaiv ntawm silicone lossis acrylic sealant, feem ntau cov hybrid muaj pes tsawg leeg yuav daws qhov teeb meem no. Nws raug nqi ntau dua li cov khoom qub, tab sis tseem pheej yig dua li polyurethane.
Xaiv lub sealant zoo tshaj
