Oily lossis greasy surfaces:Txhua qhov chaw uas muaj cov roj, roj, lossis siv quav yeeb tuaj yeem tiv thaiv kom tsis txhob muaj adhesion zoo.
Qee lub tshuaj pleev xim:Qee cov xim av, cov tshuaj vanish, lossis cov sealists tuaj yeem tsim kev thaiv kom muaj pu ua npuas tsis tau ua raws li tsis tau ua tiav.
Du, tsis muaj-nto ntug:Cov chaw ua kom du heev, xws li iav lossis polished cov hlau, tej zaum yuav tsis muab cov qauv siv kom txaus rau kev tuav.
Ntub dej lossis dej noo:PU ua npuas ncauj yuav tsum muaj qhov chaw qhuav rau kev pom zoo nkauj; Thov nws mus ntub cov chaw ntub tuaj yeem ua rau kev sib raug zoo.
PU Ua npuas ncauj thov
1. Zoo tshaj plaws rau mounting rwb thaiv tsev rwb thaiv tsev thiab sau voids thaum lub sij hawm nplaum.
2. Qhia rau cov ntoo hom khoom siv cov khoom nplaum kom muaj pob zeb ua, hlau thiab lwm yam.
3. Cov ntawv thov xav tau qhov kev nthuav dav tsawg kawg nkaus.
4. Mounting thiab rho tawm rau cov ntas ntawm lub qhov rais thiab qhov rooj.
Nta
Nws yog ib qho kev sib xyaw ua ke, kev lag luam hom thiab kev ua yeeb yam zoo polyurethane ua npuas ncauj. Nws yog haum nrog lub taub hau yas adapter rau siv phom ua npuas dej lossis cov quav cab. Cov npaus yuav nthuav dav thiab kho los ntawm ya raws hauv huab cua. Nws yog siv rau ntau cov ntawv thov tsev. Nws yog qhov zoo heev rau kev sau thiab sib khi nrog zoo mounting maub cia muaj peev xwm, muaj kev rwb thaiv tsev thiab acoustical. Nws yog ib puag ncig tus phooj ywg thaum nws tsis muaj cov khoom CFC.

Dab tsi yog qhov sib txawv ntawm kev hu seavant thiab silicone sealant?
Qhov sib txawv ntawm polyurethane (PU) Fuab thiab Silicone Sealant yog qhov tseem ceeb, raws li txhua hom muaj nws tus kheej cov khoom ntiag tug thiab cov ntawv thov zoo tagnrho. Ntawm no yog qhov sib txawv tseem ceeb:
1. Cov txheej txheem kho tau:
PU Sealant: Ua los ntawm polyurethane, nws kho los ntawm cov tshuaj lom neeg tshuaj lom neeg nrog noo noo hauv huab cua. Nws feem ntau nthuav tawm thaum daim ntawv thov, sau cov gapaps zoo.
Silicone Sealant: ua los ntawm silicone polymers, nws kho los ntawm ib tug txheej txheem hu ua "kho tus kheej," uas tsis xav tau noo noo. Nws tseem yoog raws tom qab kho.
2. Adhaesion:
Pu Sealant: Feem ntau muaj cov nplaum zoo rau ntau hom substrates, suav nrog cov ntoo, suav nrog cov ntoo, hlau, thiab pob zeb. Nws tuaj yeem ua daim ntawv cog lus tau zoo rau cov nplaim hluav taws xob thiab cov chaw uas tsis pom zoo.
Silicone sealant: kuj zoo rau ntau qhov chaw, tab sis nws cov nplaum tuaj yeem ua tau zoo rau qee yam ntaub ntawv zoo li cov plastics lossis oily surfaces.
3. Yooj thiab Zog:
PU Sealant: Muaj kev hloov pauv tau zoo tab sis tuaj yeem yog tsawg dua elastic dua li silicone. Nws yog qhov tsim nyog rau cov ntawv thov uas qee qhov kev txav mus los xij yuav tsum tsis txhob kov huab kev txav mus los zoo li silicone.
Silicone sealant: hloov tau yooj yim yam tsis muaj kev tawg lossis ua kom zoo rau cov pob qij txha uas paub nthuav dav thiab cog lus.
4. Lub Neej thiab Huab Cua Kuj:
Pu Sealant: Feem ntau tiv taus UV teeb thiab huab cua, tab sis yuav ua tsis tau lub sijhawm ncaj qha yog tias raug rau kev tiv thaiv ncaj qha tsis muaj txheej tiv thaiv.

5. Kub Kuj:
Pu Sealant: tuaj yeem tiv thaiv ntau qhov kub tab sis yuav tsis ua yeeb yam nrog rau huab cua sov lossis txias rau silicone.
Silicone sealant: feem ntau muaj qhov kub kub kub ua kom muaj kev tiv thaiv kub, ua rau nws haum rau cov ntawv thov kub-.
6. Daim ntaub ntawv:
Pu Sealant: feem ntau yog siv rau kev tsim kho, rwb thaiv tsev, thiab sib khi cov khoob hauv cov phab ntsa, vov tsev, thiab ib ncig ntawm lub qhov rais thiab qhov rooj.
Silicone sealant: feem ntau siv nyob rau hauv chav dej, chav ua noj, thiab lwm thaj chaw uas cov dej tsis yeem ntawm tog, cov tub, thiab nqais.
7. Paintility:
Pu Sealant: Feem ntau yog pleev xim rau dhau ib zaug kho, ua kom haum rau cov ntawv thov uas yog qhov tseem ceeb.
Silicone sealant: feem ntau tsis tau pleev xim, raws li cov xim pleev xim tsis ua kom zoo rau cov chaw silicone.
