Tsatanetsatane wa Zamalonda
CAS: 79-10-7
1.Acrylic acid ndi osavuta kwambiri unsaturated carboxylic acid, yokhala ndi mamolekyu opangidwa ndi gulu la vinyl ndi gulu la carboxyl.Pure acrylic acid ndi madzi opanda mtundu, omveka bwino okhala ndi fungo losasangalatsa.Kachulukidwe 1.0511.Malo osungunuka 14°C.Malo otentha 140.9°C.Ndi acidic kwambiri.Zowononga.Zosungunuka m'madzi, ethanol ndi ether.Chemical yogwira Chemicalbook.Mosavuta polymerized mu mandala woyera ufa.Amapanga propionic acid akachepetsedwa.Amapanga 2-chloropropionic acid akawonjezeredwa ndi hydrochloric acid.Ntchito yokonza akiliriki utomoni, etc. Komanso ntchito zina organic synthesis.Amapangidwa ndi makutidwe ndi okosijeni wa acrolein kapena hydrolysis wa acrylonitrile, komanso apanga kuchokera acetylene, carbon monoxide ndi madzi, kapena opangidwa ndi makutidwe ndi okosijeni wa ethylene ndi carbon monoxide pansi papsinjika.
2.Acrylic acid imatha kukhala ndi mawonekedwe a carboxylic acid ndipo ma esters ogwirizana nawo amatha kupezeka pochita ndi ma alcohols.Ma esters odziwika kwambiri a acrylic ndi methyl acrylate, butyl acrylate, ethyl acrylate, ndi 2-ethyl.
3.Acrylic acid ndi esters ake, paokha kapena osakanikirana ndi ma monomers ena, amapangidwa ndi polymerization kuti apange homopolymers kapena copolymers.Ma monomers wamba omwe amatha kuphatikizidwa ndi acrylic acid akuphatikizapo amides, Chemicalbook acrylonitrile, vinyl-containing, styrene ndi butadiene.Ma polimawa amagwiritsidwa ntchito popanga mapulasitiki osiyanasiyana, zokutira, zomatira, ma elastomer, opukuta pansi ndi utoto.
Kugwiritsa ntchito
1.Main ntchito madera: (1) warp sizing zinthu zokonzedwa ndi acrylic acid, methyl acrylate, ethyl acrylate, acrylonitrile, ammonium polyacrylate ndi zipangizo zina, Chemicalbook kuposa polyvinyl mowa sizing zinthu mphamvu desizing, kupulumutsa wowuma.(2) zomatira ndi asidi akiliriki, methyl acrylate, ethyl acrylate, akiliriki asidi-2-ethylhexyl ndi lalabala copolymer, angagwiritsidwe ntchito electrostatic akukhamukira, zomatira akukhamukira, kulimba kwake ndi kumva bwino.(3) madzi thickener ndi asidi propionic ndi ethyl acrylate copolymer zopangidwa mkulu molecular kulemera ufa.Angagwiritsidwe ntchito monga thickening wothandizira, ntchito m'minda mafuta, tani iliyonse mankhwala akhoza kuonjezera kupanga 500t ya mafuta yaiwisi, zotsatira za kuchira mafuta pa zitsime akale bwino.(4) TACHIMATA pepala kutsirizitsa wothandizira ndi acrylic asidi, butyl acrylate, akiliriki asidi-2-ethylhexyl ester, styrene ndi ena quaternary copolymer latex kwa TACHIMATA pepala ❖ kuyanika pepala, posungira mtundu popanda chikasu, ntchito yabwino yosindikiza, osati zodzigudubuza zomata, kuposa styrene butyl. latex imatha kupulumutsa kuzizira kowuma.(5) polyacrylic asidi salt ntchito akiliriki asidi akhoza kupanga zosiyanasiyana polyacrylic acid mchere (monga ammonium salt, sodium salt, potaziyamu mchere, zotayidwa mchere, faifi tambala mchere, etc.).Amagwiritsidwa ntchito ngati coagulant, wothandizira madzi, dispersant, thickener, asidi posungira chakudya ndi alkali kugonjetsedwa desiccant, softening wothandizira ndi mitundu ina ya polima zina.
2.Kukonzekera ma polima ndi homopolymerization kapena copolymerization kwa zokutira, zomatira, utomoni olimba, akamaumba mankhwala, etc.
