Kodi Beylene Glycol ndi chiyani? Kusanthula kwathunthu kwa mankhwalawa
Kodi kandadilol ndi chiyani? Dzinalo limatha kumveka mosadziwika kwa anthu ambiri, koma andyannediiol (1,4-qdodeniiol, bdo) amatenga gawo lofunikira kwambiri pamakampani azamankhwala komanso tsiku ndi tsiku. Nkhaniyi ikuthandizani mwatsatanetsatane zomwe zimagwiritsidwa ntchito ndi kugwiritsa ntchito katswiri wa kanda ndi kufunika kwake m'mafakitale osiyanasiyana.
I. Mankhwala katundu ndi kapangidwe ka kandadiol
Kodi kandadilol ndi chiyani? Kuchokera pamalingaliro a mawonekedwe, busanieniol ndi gulu la organic ndi magulu awiri a hydroxyl (-Oh) ndi mawonekedwe a mankhwala ndi C4H10o2. Ndiwopanda mafuta osawoneka bwino, omwe amatha kusungunuka osiyanasiyana monga madzi, mowa, malalanje, ndi zina zowonjezera. Chifukwa cha mawonekedwe ake a ma hydroxyl awiri, andNeniol m'mankhwalawa amawonetsa kuti zimachitika mwachikhana, amatha kutenga nawo mbali mu esteremirition, kukhazikika, polycondenstivensl.
Chachiwiri, kugwiritsa ntchito kwakukulu kwa kanda
Kuyang'ana zomwe ayansiyo singalekanitsidwe ndi ntchito yakenso. Nyanchne Glycol imagwiritsidwa ntchito popanga ma polima, ma sol sols ndi mankhwala ofunikira mankhwala.
Kupanga kwa polymerniol: andanesiol ndi chinthu chofunikira chopangira kuti polmurethane ndi polyester. Mu polyurethane kupanga, imagwiritsidwa ntchito ngati mawonekedwe owuma ndi gawo lofewa kuti apereke malonda kukhala olemera komanso kuvala. Mu kupanga polsterter, andylene glycol ndi malo ofunikira opangira polmoplastic polyester (mwachitsanzo PBT) ndi osavomerezeka polyester.

Masungunuke: Chifukwa cha kusandulika kwake kwabwino, asylene glycol amagwiritsidwanso ntchito ngati zosungunulira zosiyanasiyana m'makampani amagetsi, zokutira, zotupa ndi zodzola. Makamaka muzodzikongoletsera, andylene glycol amachita ngati hypol ndi solvent, akuthandiza kukonza zotayika ndi maudindo.

Mankhwala Opata wa mankhwala ophera tizilombo, mankhwala osokoneza bongo komanso ma sol sol.

Chachitatu, kupanga kwa kandadiol
Kumvetsetsa komwe katswirini ndi, muyenera kuyang'ana pazinthu zake. Pakadali pano, njira zazikulu zopanga bongo zimaphatikizira:
Njira yochepetsetsa ya Aldeyde: Izi ndi zomwe zimagwiritsidwa ntchito kwambiri, kudzera mwa acetaldehyde ndi formaldehyde kuti mupange 1,3-dioxonel, kenako ndikuwotcha kuti mupange dzina. Njirayi imakhala ndi maubwino okhwima komanso mtengo wotsika mtengo.

Njira ya Ethylene oxide: Ethylene oxide watachitika ndi kaboni dayokisi pansi pa chothandizira cha vinyl carbonate, yomwe imatha kupanga yansadiol. Zomwe zimachitika mwanjira imeneyi zimakhala zofatsa, koma kugulitsanso mu zida ndizokwera.

Iv. Ziyembekezerero za Metaneeniiol
Kukambirana zomwe dzina lake, ndikofunikira kufufuza zomwe amayembekeza. Ndi zomwe zimachitika padziko lonse lapansi zopangira zinthu zolimbitsa thupi, zomwe zimafunikira pamsika ya andaneeneeneol ndizomeranso chaka ndi chaka. Makamaka pantchito yamagetsi, magalimoto atsopano amagetsi komanso zachilengedwe zachilengedwe, zomwe akufuna kulonjeza.
Popita patsogolo kwa ukadaulo, kafukufuku komanso chitukuko cha butaneya wa bio. Kugwiritsa ntchitotu kwatsatanetsatane kumeneku kudzakulitsanso malo amsika wa andaniyol komanso amathandizanso kuchepetsa kudalira kwa zinthu za serochemical.
Mapeto
Kodi kandadilol ndi chiyani? Sikuti ndi mankhwala ofunikira omwe ali ndi mapulogalamu angapo mafakitale angapo, komanso amakopa chidwi ndi mitundu yake yosiyanasiyana ya mankhwala ndi kusiyanasiyana. M'tsogolomu, ndi ntchito yaukadaulo ndikufuna kwa msika, butaneyael ikuwonetsa mtengo wake wofunika m'minda yambiri.
