Gaas-gacmeedka shuban ayaa laga jaraa xaashida caagga ah ama caaryada. Qiyaaso iyo qaabab kasta ayaa la soo saari karaa. Haddii aad u baahan tahay hal qayb, ama hal malyan oo qaybood, qaybtayada guntan waxay gooyn kartaa wax kasta oo qiyaasta iyo qaabka aad qiyaasi karto, laga bilaabo wax kasta oo wax walba ah.
SBR Qashin Kiimikada
Sharaxaad: Rubber waa qalabka ugu kharashka badan ee waxtar leh si loo isticmaalo meesha heerkulka iyo cadaadiska ay hoos u dhacaan
deegaanka kiimikada waa mid khafiif ah. Alastomers kala duwan waxay bixiyaan guryaha farsamooyinka iyo kiimikooyinka kala duwan. Dhar
qalabka lagu xiro ayaa si fiican u awoodi kara in ay qabtaan dhaqdhaqaaqa iyo culeyska sare ee culeyska.
Rubbergasket waa la jaraa ama waxaa laga sameeyay NBR, SBR, CR, EPDM. Qaar ka mid ah gogolka caaggu waxay leeyihiin iska-caabbinta saliid, Qaar ka mid ah
caag ah gasket is used in cold fever, Some caag ah gasket has anti-aging properties.There are various shapes of
caag ah gaas Nooca dhuxusha waxaa lagu isticmaalaa daawada, qalabka elektarooniga ah, Kiimikooyinka, dabiiciga ah, dab-demiska, cuntada
iyo other industries.Other caag ah gaskets: neoprene caag ah gogosha, natural caag ah gogosha, EPDM caag ah
gogosha, acrylicplastic caag ah gaskets iyo other special caag ah gaskets.
SBR (Styrene-butadiene):SBR is a copolymer of styrene iyo butadiene iyo has properties similar to Natural Rubber.
Waxeey heesataagood abrasion resistance, excellent impact strength, very good resilience iyo a high tensile strength.
Silicon Rubber Gasket: Silicon caag ah gasket(FDA Qalabkas Approved) has outstiyoing low-temperature-resistant
waxqabadka sare. BIK-silicon caag ah gasket can be used in -70℃ - +260℃ temperature range. Silicon caag ah gasket
sii wad isticmaalka wanaagsan ee bamamka.
Nitril-butadiene caag ah gasket(NBR):Waa kaniiniga nitril butadiene ee polymer emulsion. Nitril-butadiene
caag ah Gaaska BIK-30207B wuxuu leeyahay cilad saliideed aad u fiican (laakiin ketones dulqaad la'aan, esters iyo chlorinated hydrocarbons,
iyo other media). It also has a good abrasion resistance, anti-aging iyo air adkeysi iyo therefore the application
of the caag ah industry Wide.
Fluorine Rubber Gaskets：Fluorinecaag ah gaskets can be used in a high temperature from -30℃ to +250℃. Waxeey heesataa
the use of the environment, resistant to strong oxidant, oil. And normally, Fluorine caag ah gaskets are used waayo sarraysa
heerkulka, high vacuum iyo high-pressure environment. Fluorine caag ah gaskets is also suitable jawiga shidaalka.
Sida oo dhan high-performance, fluorine caag ah is widely used in petroleum, chemical, aviation iyo aerospace sectors.
Other caag ah gasket: Neoprene Shooladda Kumbuyuutarka (CR), Dhuxulada Dhuxul-dabiiciga ah (NR), Shirkadda EPDM, ceymiska.
