Tom qab ntawd koj yuav tsum tau nyeem cov lus no kom zoo, Kuv yuav coj koj los nkag siab qhov txawv ntawm cov nplaum no thiab lawv siv, yog li koj tsis tas yuav txhawj xeeb txog kev xaiv cov nplaum tsis raug. Nco ntsoov bookmark nws. Tam sim no cia peb mus dhau ntawm kab lus no ua ntej kom nkag siab txog lub sealant.
- Lub tsev sealants raug categorized raws li lawv cov tshuaj muaj pes tsawg leeg.
- Ua qhov kev faib tawm hauv qab no
Raws li chemical compositintawm, hom sealants yuav muab faib ua silicone, polysulfide, polyhexyl ester, silane-hloov, roj hmab, acrylate.
- Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm cov kua nplaum no
Silicone: qhov kom zoo dua yog huab cua tiv taus,qhov tsis zoo yog tias cov nplaum ntau yog me me painting tsis zoo.
Polysulfide: qhov kom zoo dua yog cov dej vapor kis tau tus nqi tsawg, qhov tsis zoo yog cov cua sov tsis zoo, huab cua tsis zoo.
Polyhexyl ester: Qhov zoo yog qhov sib txuas ntawm ntau yam thiab tuaj yeem pleev xim, tab sis qhov tsis zoo yog qhov tsis zoo ntawm cov cua sov, huab cua tsis zoo.
Silane hloov chav kawm: qhov zoo ntawm ntau yam kev sib txuas, txhuam zoo huab cua, kev tiv thaiv ib puag ncig, qhov tsis zoo yog tias tsis muaj qhov tsis zoo, tsis muaj cov qauv tsim khoom.
Roj Hmab: qhov zoo ntawm ntau yam kev sib txhuam txhuam zoo, qhov tsis zoo yog huab cua tsis zoo rau lub cev tsis zoo.
Acrylates: qhov zoo ntawm kev tiv thaiv ib puag ncig, qhov tsis zoo yog qhov kev tsim kho ib puag ncig yuav tsum muaj siab, lub cev tsis zoo.
- Dab tsi yog qhov tseem ceeb ntawm cov kua nplaum no hauv kev tsim kho kev lag luam
Hom Silicone: tuaj yeem siv rau lub tsev qhov rooj thiab qhov rais, curtain phab ntsa bonding sealing
Polysulfide: tuaj yeem siv rau insulating iav ob lub foob
Polyhexyl ester: tuaj yeem siv rau pob zeb, hlau sib khi sealing
Silane hloov chav kawm: tuaj yeem siv rau pob zeb, hlau sib txuas sealing
Roj Hmab: tuaj yeem siv rau lub qhov rooj thiab qhov rais, sab nrauv phab ntsa sealing
Acrylates: tuaj yeem siv rau hauv tsev sab hauv.
2. Kev tsim kho sealants raug cais raws li kev thov tshwj xeeb scenarios
- Silicone structural adhesive yog tsim rau kab hlau rhuav phab ntsaassembly, siv nyob rau hauv structural bonding
- Silicone Weathersealant yog tsim rau kab hlau rhuav phab ntsa vaj huam sib luag, siv hauv kev sib koom ua ke.
- Pob zeb qhuav-dawb nplaum nplaum thiab silicone weathersealers yog tsim rau pob zeb kab hlau rhuav phab ntsa, siv rau hauv qhuav-hanging, kho thiab sib koom ua ke.
- Kub yaj butyl nplaum yog tsim rau insulating iav, siv nyob rau hauv ib daim ntawv cog lus sealing.
- Polyurethane ua npuas ncauj nplaum yog tsim rau sealing qhov rooj thiab qhov rais, siv nyob rau hauv sealing cov pob qij txha ntawm lub qhov rais thav duab thiab phab ntsa.
- Silicone sealant thiab butyl nplaum yog haum rau sealing qhov rais thiab qhov rooj, siv nyob rau hauv sealing qhov rais sash thiab ncej.
FAQ:
1. vim sealants yuav tsum tau siv cov ntaub ntawv rov qab thiab tiv thaiv peb-sab sib txuas?
Lub luag haujlwm tseem ceeb ntawm cov khoom siv rov qab yog block qhov kev sib txuas thiab tiv thaiv lub sealant los ntawm kev sib txuas ntawm peb sab, vim tias kev sib txuas ntawm peb sab cuam tshuam rau lub peev xwm txav ntawm lub sealant, ua rau tawg ntawm cov gel, kev puas tsuaj thiab lwm yam tshwm sim.
2. yog vim li cas xim sealantfading phenomenon?
Xim silicone nplaum siv inorganic lossis organic pigments rau xim sib tov. Inorganic pigments tsis tshua muaj xim, tab sis huab cua tiv taus thiab tsis yooj yim rau ploj; organic pigments yog cov yeeb yuj, tab sis huab cua resistant thiab yooj yim rau ploj.
Kev tiv thaiv:
Nws raug nquahu tias cov neeg siv khoom yuav tsum xaiv cov xim inorganic xim sib xyaw kom ntau li ntau tau thaum lawv xav tau sib tov cov xim nplaum, thiab tsis txhob ua raws cov xim sib xws ntau dhau rau cov xim ci uas yuav sib xyaw nrog cov xim organic.
3. Vim li cas sealantua tsis tau daim ntawv cog lus?
(1) Sealant thiab substrate nws tus kheej tsis stib ick.
(2) kev tsim kho tsis yog tus qauv, xws li lub substrate deg tu tsis huv, kev tu ib puag ncig lossis lub sijhawm txij nkawm tsis ua raws li qhov yuav tsum tau ua, tsis yog raws li qhov yuav tsum tau ua ntawm primer, ob lub ntsiab lus tsis raug, thiab lwm yam.
Kev tiv thaiv:
Txhua lub sealant tsis tuaj yeem lav tias tag nrho cov substrates tau zoo sib txuas, yog li kev tsim kho ntawm lub substrate yuav tsum muaj kev sib txuas thiab kev sib tw, tsim nyog ua ntej siv cov kua nplaum, yog tias tsim nyog, siv cov tshuaj primer; ua ntej siv cov kua nplaum yuav tsum yog lub substrate deg plua plav, roj thiab lwm yam av ntxuav raws li txoj kev teev tseg; ib leeg-tiv thaiv yam tsawg kawg 7 hnub, ob-txhim kho yam tsawg kawg 3 hnub nyob rau hauv cov ntaub ntawv ntawm kub thiab av noo yuav tsum ncua sij hawm txij nkawm.
