Faahfaahinta Alaabta

Tags Product

Sharaxaad:Methacrylic acid waa walxo kiimikaad oo muhiim ah oo ceeriin ah, waxay leedahay laba kooxood oo shaqeynaya oo ah kaarboon-carbon double bond iyo kooxda karboxilic acid, sidaa darteed waxay sameyn kartaa falcelin sida polymerization iyo esterification.Waxa loo isticmaali karaa buuga Kiimikada si loogu diyaariyo methyl methacrylate, dahaarka, caag synthetic, xabagta, wakiilada daawaynta dharka, resins, waxyaabaha lagu daro polymerka iyo alaabta polymer functional.

 

Codsiga:

Walxaha kiimikada ee muhiimka ah ee dabiiciga ah iyo kuwa dhexdhexaadka ah ee polymers.
1. plexiglass-ka ay soo saarto asalkiisa ugu muhiimsan, methyl methacrylate, waxa loo isticmaali karaa daaqadaha dayuuradaha iyo dhismayaasha madaniga ah, waxa kale oo lagu farsamayn karaa badhanka, filtarrada cadceedda iyo muraayadaha nalalka baabuurta, iwm.;
2. Dahaarka la soo saaray waxay leeyihiin ganaax sare, rheological iyo sifooyinka cimri dhererka ee Buuga Kiimikada;
3. Xabagta la diyaariyey waxaa loo isticmaali karaa isku-xidhka birta, maqaarka, caagagga iyo qalabka dhismaha;
4. Methacrylate polymer emulsions waxaa loo isticmaalaa sida walxaha dhamaystirka dharka iyo wakiilada antistatic.
5. Methacrylic acid waxa kale oo loo isticmaali karaa sidii alaab cayriin ah caag synthetic ah.

 

Tilmaamaha guud:Tilmaamaha halista ah ee walxaha qarxa: waxay qarxi kartaa marka hawada lagu daro;Way fududahay in la polymerize oo kululeeyo weelka si uu qarax u keeno.Flammability Astaamaha halista ah: guban kara;dabku wuxuu soo daayaa qiiq basbas leh oo xanaaq badan

 

Xidhmada:200kg miisaanka saafiga ah, ama shuruudo macmiil ahaan.

 

Gaadiidka iyo kaydinta:ku kaydi meel qabow oo qalalan, oo ka fog dabka iyo kulaylka, mamnuuc qoraxda, ka yar 30 ℃, xidhxidhan.
