Kev paub yooj yim ntawm silicone sealants

1. Kev faib tawm:

Silicone sealant tuaj yeem muab faib ua ob pawg los ntawm cov khoom ntim khoom: ib qho khoom thiab ob lub ntsiab lus. Kev kho ntawm ib leeg-tiv thaiv silicone sealant yog tshwm sim los ntawm kev hloov pauv ntawm lub cev vim muaj kev sib cuag nrog cov dej noo hauv huab cua;

Ob lub ntsiab lus silicone sealant txhais tau hais tias cov kua nplaum silicone tau muab faib ua ob pawg, A thiab B. Cov pab pawg neeg tsis tuaj yeem sib zog yog tias nws nyob ib leeg. Tab sis thaum ob txheej ntawm cov kua nplaum sib tov, lawv solidify.

Tam sim no, feem ntau ib qho ntawm kev ua lag luam yog ib qho khoom siv silicone sealant.. Ib qho khoom siv silicone sealant tau muab faib ua kua qaub silicone sealant thiab nruab nrab silicone sealant raws li lawv cov khoom.

Acid silicone sealant feem ntau yog siv rau kev sib txuas ntawm iav thiab lwm yam khoom siv hauv tsev. Cov kua nplaum nruab nrab kov yeej cov yam ntxwv ntawm cov kua qaub kua nplaum uas ua rau cov khoom siv hlau thiab ua rau cov ntaub ntawv alkaline, yog li nws muaj ntau yam kev siv thiab nws cov nqi lag luam yog me ntsis siab dua li cov kua qaub kua nplaum.

Ib hom tshwj xeeb ntawm iav kua nplaum ntawm lub khw yog silicone structural sealant. Vim hais tias nws yog siv ncaj qha rau cov hlau thiab iav qauv los yog tsis yog cov qauv kev sib txuas ntawm cov iav kab hlau rhuav phab ntsa, cov kev xav tau zoo thiab cov khoom qib yog siab tshaj ntawm cov iav nplaum. Tus nqi lag luam kuj yog siab tshaj.

2. Lub hom phiaj

(1) Acid silicone sealant (piv txwv zog 733)

① Tsim nyog rau kev sib khi, thaiv, tiv thaiv kom tsis txhob muaj cua sov. Nws yog qhov tsim nyog rau kev siv sab hauv tsev thiab sab nraum zoov (cov nyhuv sab hauv tsev yog qhov zoo dua), thiab cov nyhuv los tiv thaiv cov dej ntws tawm thiab cov dej pov thawj yog qhov zoo kawg.

② Kev sib txuas ntawm ntau yam khoom siv kho kom zoo nkauj sab hauv ntawm lub tsheb, suav nrog: hlau, fabrics thiab organic fabrics thiab plastics.

③ Txuas cov gaskets ntawm cov khoom siv cua sov thiab cua txias.

④ Txhim kho cov tav tsis muaj qhov ntsia hlau, cov npe thiab cov xim pleev xim ntxiv rau cov ntaub ntawv yas ntawm cov hlau.

⑤ Kaw lub qhov rais ntawm lub qhov cub qhov cub, lub qhov cub, cov yeeb nkab txuas, thiab cov qhov rooj nkag ntawm cov khoom siv roj.

⑥ Muab cov pa xau-pov thawj tam sim rau lub thawv iav, compressors, thiab cov twj tso kua mis.

⑦ Kaw lub cabin thiab qhov rais.

⑧ Sealing ntawm trailer thiab tsheb cab qhov rais.

⑨ Cov khoom sib khi thiab cov khoom sib khi.

⑩ Tsim cov txheej tiv thaiv hnav.

11 Inlaid thiab muaj tseeb-filled nyias hlau ntawv lamination, yeeb nkab network thiab khoom casing.

(2) Tsis muaj huab cua-resistant silicone sealant ( zog 789)

① Haum rau huab cua-resistant sealing ntawm ntau cov ntaub thaiv phab ntsa, tshwj xeeb tshaj yog pom zoo rau huab cua-resistant sealing iav ntaub phab ntsa, aluminium-yas vaj huam sib luag ntaub thaiv phab ntsa, thiab pob zeb qhuav dai;

② Seam sealing ntawm hlau, iav, txhuas, ceramic vuas, organic iav, thiab coated iav;

③ Seam sealing ntawm pob zeb, cement, masonry, pob zeb, marble, steel, ntoo, anodized txhuas thiab pleev xim rau txhuas qhov chaw. Feem ntau tsis tas yuav siv primer.

(3) Silicone structural nplaum (zog 793)

① Feem ntau yog siv rau cov khoom siv los yog cov khoom siv sib txuas ntawm cov hlau thiab cov iav ntawm cov iav kab hlau rhuav phab ntsa.

② Nws tuaj yeem txuas ncaj qha rau iav rau saum npoo ntawm cov khoom siv hlau los tsim ib qho kev sib dhos, ua tau raws li cov qauv tsim ntawm cov ntaub thaiv phab ntsa nrog tag nrho lossis ib nrab zais thav ntawv.

③ Cov qauv kev sib txuas thiab kev sib khi ntawm cov iav insulating.

3. Kev txwv

Txhua yam ntawm silicone sealant yog raug rau cov kev txwv hauv qab no thaum siv:

① Nws tsis haum rau kev tsim kho hauv qhov chaw uas tau ntub dej rau lub sijhawm ntev;

② Nws tsis sib xws nrog cov ntaub ntawv uas yuav xau roj, plasticizers lossis cov kuab tshuaj;

③ Nws tsis tuaj yeem siv rau ntawm qhov chaw frosted lossis ntub dej. Adhesion;

④ Nws tsis tuaj yeem kho tau hauv qhov chaw kaw tag nrho (silica gel yuav tsum tau kho los ntawm cov dej noo hauv huab cua);

⑤ Qhov saum npoo ntawm lub substrate tsis huv los yog muaj zog.
