MOCA,inozivikanwawo se 4,4′-Methylenebis(2-chloroaniline), ichena kusvika kuchiedza yero yakasununguka yekristaro yetsono inoshanduka dema kana yapiswa.Mushonga uyu unosiyana-siyana unonzi hygroscopic uye unonyungudika mumaketoni nemahydrocarbon anonhuwirira.Asi chii chinoisa MOCA mutsauko ndeye huwandu hwayo hwekushandisa uye zvigadzirwa zvemhando.
Chemical properties:white to light yellow loose needle crystal, inopisa kuita black.Zvishoma hygroscopic.Soluble mumaketone uye anonhuwirira hydrocarbons.
MOCA inonyanya kushandiswa seyakavhuvhuta agent ye cast polyurethane rabha.Yayo crosslinking zvimiro inoita kuti ive sarudzo yakanakisa yekusimudzira kusimba uye kusimba kwezvinhu zverubha.Pamusoro pezvo, MOCA inoshanda seyakachinjika mumiriri kune polyurethane coatings uye zvinonamira, ichipa kunamira kwakavandudzika uye kuita.Uyezve, musanganiswa uyu unogona kushandiswa kurapa epoxy resins, zvichiita kuti ive chinhu chakakosha mumaindasitiri akasiyana.
Uyezve, kuwirirana kweMOCA kunosvika kune akasiyana mafomu.Liquid MOCA inogona kushandiswa se polyurethane kurapa mumiririri pakamuri tembiricha, ichipa zviri nyore uye kuchinjika mukushandisa.Inogona zvakare kushandiswa se polyurea yekurapa mumiriri wekupfapfaidza, ichiwedzera kuwedzera huwandu hwayo hwekushandisa.
Zvakanakira uye maapplication:
Kana zvasvika kumunda wepolyurethane rubha uye machira, kuwana iyo chaiyo vulcanizing uye crosslinking mumiriri kwakakosha.Apa ndipo apo MOCA (4,4'-Methylene-Bis-(2-Chloroaniline)) inotora nzvimbo yepakati.Nezvimiro zvayo zvakasarudzika uye kuwanda kwekushandisa, MOCA yave yakakosha mumaindasitiri akasiyana.
MOCA inozivikanwa nekutaridzika kwayo senge chena kusvika kuchiedza yero yakasununguka tsono crystal, inoshanduka dema kana yaiswa mukupisa.Pamusoro pezvo, ine zvishoma hygroscopic zvimiro uye inonyungudika mumaketoni uye anonhuwirira mahydrocarbon.Aya maitiro anoita kuti ive yakakodzera mumiriri wekushandiswa mune akasiyana maitiro ekugadzira.
Imwe yemabhenefiti akakosha eMOCA ibasa rayo semumiriri wevulcanizing for cast polyurethane rubber.Nekuyambuka cheni dzepolymer, MOCA inosimudzira kusimba uye kusimba kwerabha.Izvi zvinovimbisa kuti chigadzirwa chekupedzisira chinogona kumira nemamiriro ezvinhu akaoma uye kuchengetedza kutendeseka kwayo kwenguva yakareba.
Uyezve, MOCA inoshanda seyakanakisa crosslinking agent ye polyurethane coatings uye adhesives.Iyo inosimudzira kemikari kubatana pakati pemapolymer mamorekuru, zvichikonzera machira uye anonamira anoratidza kushanda kwepamusoro.Zvingave zvemachira ekudzivirira kana zvekunamira zvechimiro, MOCA inopa simba rinodiwa uye kugadzikana.
Pamusoro pekushandisa kwayo murabha uye machira, MOCA inogona zvakare kushandiswa kurapa epoxy resins.Nekuwedzera zvidiki zveMOCA, iyo epoxy resin inogona kupinda muchinjika maitiro, zvichitungamira kune yakagadziridzwa michina uye yekupisa zvivakwa.Izvi zvinoita kuti MOCA ive chishandiso chakakosha kumaindasitiri anovimba ne epoxy resins yezvigadzirwa zvavo uye maapplication.
Uyezve, kune fomu yemvura yeMOCA inozivikanwa seMoka.Musiyano uyu unogona kushandiswa se polyurethane kurapa mumiriri patembiricha yekamuri, zvichiita kuti zvive nyore kune maitiro ekugadzira.Pamusoro pezvo, Moka inogona kushanda se polyurea kurapa mumiriri wekupfapfaidza zvikumbiro.Kusarudzika kwayo uye nyore kushandisa kunoita kuti ive sarudzo yakakurumbira pakati pevagadziri.
Packaging uye kuchengetedza:
Packaging:50kg/DRUM
Storage:inofanira kutonhorera, yakaoma uye inofefetera.
Kugadzikana:Kupisa uye kushanduka dema, hunyoro hushoma.Iko hakuna yakadzama pathological bvunzo muChina, uye haina chokwadi chekuti chigadzirwa ichi chine muchetura uye chinokuvadza.Chigadzirwa chacho chinofanira kusimbiswa kuti chideredze kusangana neganda uye kufema kubva pamhepo yekufema, uye kuderedza kukuvadza kumuviri wemunhu zvakanyanya sezvinobvira.
Summary:
Kuzvipfupikisa, MOCA (4,4'-Methylene-Bis-(2-Chloroaniline)) inoshanda zvakasiyana-siyana uye yakakosha vulcanizing uye crosslinking agent.Kuwanda kwayo kwakasiyana-siyana kwekushandisa mu polyurethane rabha, machira, uye anonamira indasitiri inoita kuti ive yekuenda-kusarudzo kune vanogadzira.Nekugona kwayo kuwedzera simba, kusimba, uye hukama hwemakemikari, MOCA pasina mubvunzo inoita basa rakakosha mukuona kunaka uye kuita kwezvigadzirwa zvakasiyana.
