MOCA,inozivikanwawo se4,4′-Methylenebis (2-chloroaniline), ikristaro yetsono yakapfava kubva kune chena kusvika kune yero yakajeka iyo inoshanduka kuita dema kana yapiswa. Musanganiswa uyu une hunyanzvi hwakasiyana uye unonyungudika muketones uye aromatic hydrocarbons. Asi chinosiyanisa MOCA nemashandisirwo ayo uye maficha ayo.
Hunhu hwemakemikari:Crystal yetsono yakachena kubva kuchena kusvika kune yero yakapfava, inopisa kusvika kudema. Inonyungudika zvishoma. Inonyungudika mumaketoni nemahydrocarbon anonhuhwirira.
MOCA inonyanya kushandiswa sechinhu chinosanganisa rabha yepolyurethane. Hunhu hwayo hwekubatanidza zvinhu zvinoita kuti ive sarudzo yakanaka yekusimbisa kusimba uye kugara kwenguva refu kwezvinhu zverabha. Pamusoro pezvo, MOCA inoshanda sechinhu chinosanganisa zvinhu zvepolyurethane, ichipa kunamira kwakanaka uye kushanda zvakanaka. Uyezve, chinhu ichi chinogona kushandiswa pakugadzirisa ma resin epoxy, zvichiita kuti ive chinhu chinokosha mumaindasitiri akasiyana-siyana.
Uyezve, MOCA inogona kushandiswa zvakasiyana-siyana mumhando dzayo dzakasiyana. MOCA yemvura inogona kushandiswa semushonga wepolyurethane patembiricha yemumba, zvichiita kuti ive nyore kushandisa uye ive nyore kushandisa. Inogona kushandiswawo semushonga wepolyurea pakufafaza, zvichiwedzera kushandiswa kwayo.
Zvakanakira uye mashandisirwo：
Kana zvasvika pakugadzira rabha nepurasitiki, kutsvaga chinhu chakakodzera chekubatanidza zvinhu. Apa ndipo panonyanya kukosha MOCA (4,4'-Methylene-Bis-(2-Chloroaniline)). Nehunhu hwayo hwakanaka uye mashandisirwo akasiyana-siyana, MOCA yave chinhu chikuru mumaindasitiri akasiyana-siyana.
MOCA inozivikanwa nekutaridzika kwayo sekristaro chena kusvika cheyero yakapfava, iyo inoshanduka kuita dema kana yaiswa pakupisa. Pamusoro pezvo, ine hunhu hushoma hwe hygroscopic uye inonyungudika mumaketone nemahydrocarbon anonhuhwirira. Hunhu uhwu hunoita kuti ive yakakodzera kushandiswa mumabasa akasiyana ekugadzira.
Chimwe chezvakanakira zvikuru zveMOCA ibasa rayo semushonga wekugadzira rabha yepolyurethane yakagadzirwa nesimbi. Nekubatanidza cheni dzepolymer, MOCA inowedzera simba uye kugara kwenguva refu kwerabha. Izvi zvinoita kuti chigadzirwa chekupedzisira chigone kumira mumamiriro ezvinhu akaoma uye kuchengetedza kunaka kwacho kwenguva yakareba.
Uyezve, MOCA inoshanda senzira yakanaka kwazvo yekubatanidza machira epolyurethane neadhesive. Inokurudzira kubatana kwemakemikari pakati pemamorekuru epolymer, zvichikonzera machira neadhesive anoratidza kushanda kwepamusoro. Ingave iri yeadhesive inodzivirira kana adhesive yekuvaka, MOCA inopa simba rinodiwa uye kugadzikana.
Pamusoro pekushandiswa kwayo murabha nependi, MOCA inogonawo kushandiswa pakugadzirisa ma epoxy resin. Nekuwedzera huwandu hushoma hweMOCA, epoxy resin inogona kuita crosslinking reaction, zvichikonzera kuvandudzwa kwehunhu hwemakanika nekupisa. Izvi zvinoita kuti MOCA ive chishandiso chakakosha kumaindasitiri anovimba nema epoxy resin pazvigadzirwa zvavo nekushandiswa.
Uyezve, kune mhando yeMOCA yemvura inozivikanwa seMoka. Iyi mhando inogona kushandiswa semushonga wepolyurethane patembiricha yemumba, zvichiita kuti ive nyore kugadzira. Uyezve, Moka inogona kushanda semushonga wepolyurea wekushandisa pakupfapfaidza. Kugona kwayo kushandiswa kwakasiyana-siyana uye nyore kushandisa kunoita kuti ive sarudzo inozivikanwa pakati pevagadziri.
Kurongedza nekuchengetedza：
Kurongedza:50kg/DRUM
Kuchengetera：inofanira kunge iri panzvimbo inotonhorera, yakaoma uye inofefetedza mweya.
Kugadzikana:Kupisa uye kuita dema, hunyoro hushoma. Hapana bvunzo yakadzama yezvirwere muChina, uye hazvina chokwadi chekuti chigadzirwa ichi chine chepfu uye chinokuvadza. Mudziyo unofanirwa kusimbiswa kuderedza kusangana neganda uye kufema kubva mumhepo yekufema, uye kuderedza kukuvara kumuviri wemunhu zvakanyanya sezvinobvira.
Pfupiso：
Muchidimbu, MOCA (4,4'-Methylene-Bis-(2-Chloroaniline)) imushonga unoshanda zvakanyanya uye unobatsira zvikuru. Mashandisirwo ayo akasiyana-siyana muindasitiri yerabha, machira, uye manamatisi epolyurethane anoita kuti ive sarudzo inofarirwa nevagadziri. Nekugona kwayo kuwedzera simba, kugara kwenguva refu, uye kubatana kwemakemikari, MOCA haina mubvunzo kuti ine basa rakakosha mukuona kuti zvigadzirwa zvakasiyana-siyana zvakanaka uye zvinoshanda.
