Pfupiso yeChigadzirwa

Maleic anhydride (CAS Nhamba: 108-31-6) ianhydride yakakosha isina kuguta ine fomura yemakemikari yeC₄H₂ZVINO₃Inotaridzika sema crystalline flakes machena kana yero yakajeka ine hwema hunopisa, inoshanda zvakanyanya, uye inoenderana zvakanaka nema monomers akasiyana-siyana uye makemikari. Sezvinhu zvemakemikari eorganic zvinoshanduka-shanduka, inoshandiswa zvakanyanya muma polymers, coatings, pharmaceuticals, kurima, uye maindasitiri emafuta negasi, ichipa mashandiro akagadzikana uye mhando yakavimbika yekugadzira maindasitiri.

Mashandisirwo & Mashandisirwo

Kushandiswa kwakawanda kweMaleic Anhydride kunoita kuti ishandiswe mumabasa akasiyana-siyana:

MaResins ePolyester Asina Kuzara (UPR)

Mashandisirwo Akakosha: Inopfuura 50% yekugadzirwa kweMA pasi rose inoshandiswa muUPRs.

Zvigadzirwa zveKupedzisira Kushandiswa: Mapurasitiki akasimbiswa nefiberglass, matangi, mapaipi, zvikamu zvemotokari, maburi echikepe, uye mapaneru ekuvaka.

MaCopolymer

Zvinowedzerwa mumafuta emafuta: Zvinoshandiswa mu copolymers dzinoshanda sezvinhu zvinovandudza uye zvinoparadzira viscosity index.

Kuputira Pamusoro: Chinhu chisina kugadzirwa chealkyd resins chinoshandiswa mumapendi emhando yepamusoro uye mapendi emuindasitiri.

Makemikoro Ekurima

Pakati nepakati: Inoshandiswa mukugadzira mishonga yezvipembenene, mishonga yesora (semuenzaniso, Malathion), uye zvinodzora kukura kwezvirimwa.

Zvekuwedzera Zvekudya

Fumaric neMalic Acid: Maleic Anhydride ndiyo inotangira maasidhi asina chepfu aya, anoshandiswa seasidulants muzvinwiwa nezvikafu.

Mamwe Mapurogiramu

Saizi Yepepa: Inoshandiswa mukugadzira alkyl ketene dimer (AKD), chinhu chinowanzo shandiswa pakugadzira saizi yepepa.

Tetrahydrofuran (THF) / Gamma-Butyrolactone (GBL): Cis-Butenedioic Anhydride inzira yakakosha yekugadzira zvinonyungudutsa izvi zvinokosha.

Succinic Anhydride: Inoshandurwa nyore nyore kuita succinic anhydride yekugadzira makemikari akasiyana-siyana.

Zvakanakira Chigadzirwa

2 5-Furandine High Purity: Kuchena ≥ 99.5% kunoita kuti mhinduro irambe yakasimba uye kunoderedza zvigadzirwa zvinobva mukugadzirwa kwemuchina.

Hunhu Hunogara Huchienderana: Kudzora hunhu kwakasimba mukati mekugadzirwa (kubva pakusarudza zvinhu zvakabikwa kusvika pakuongororwa kwechigadzirwa chapera) kunoita kuti chigadzirwa chirambe chichienderana.

Kushanda Zvakanaka Kwazvo: Kushanda kwakanyanya kwema diol, amines, uye monomers kunoita kuti zvigadzirwa zvemumvura zvisanganisirwe zvakanaka.

Kugadzira Zvisina Kusvibisa Zvisikwa: Kunoshandisa tekinoroji yepamusoro yekugadzira ine simba shoma uye marara mashoma, zvichitevedzera mitemo yepasi rose yezvakatipoteredza.

Kurongedza & Kuchengeta Maleic Anhydride Acid

Kurongedza: 25kg huremu hwese pabhegi repepa rekraft (rine polyethylene liner yemukati) kana 1000kg mabhegi makuru, akakodzera kutakurwa mugungwa nenyika.

Kuchengetera: Chengeta mudura rinotonhorera, rakaoma, rine mhepo inofefetera zvakanaka, kure nekupisa, moto wakavhurika, uye ma oxidant akasimba. Dzivisa kunyungudika kwehunyoro (kunogona kuita maleic acid) uye chiedza chezuva chakananga. Nguva yekuchengeta: mwedzi gumi nemiviri kana zvinhu zvakachengetwa zvakanaka.

Kuchengetedzwa uye Kubatwa kweCis-Butenedioic Anhydride

Kuzvidzivirira: Pfeka magirovhosi, magogorosi, uye chifukidziro cheguruva chisingapindi makemikari paunenge uchibata. Dzivisa kusangana zvakananga neganda, maziso, uye nzira dzekufema.

Rubatsiro Rwekutanga: Kana ganda rakabatana, sukurudza nemvura yakawanda nekukurumidza kwemaminitsi gumi nemashanu; kana rakabatana mumaziso, sukurudza nemvura wotsvaga rubatsiro rwechiremba. Kana rapinda mumhepo, enda kumhepo itsva wobvunza chiremba.

Kubata Kudururwa Kwemvura: Nywa zvinhu zvakadururwa zvine zvinonwisa mvura zvisina simba (semuenzaniso jecha, vermiculite), unganidza mumidziyo yakavharwa, woirasa zvichienderana nemitemo yenharaunda. Usadururire mvura kana ivhu.
