MXC-B20 - Chinhu chinosimudzira kushandiswa kwepolyurethane chinobva mu bismuth

MXC-B20 imhando yebismuth catalyst inogona kukurumidzisa kugadzirwa kwepolyurethane ukuwo ichifunga nezvekuchengetedzwa kwezvakatipoteredza. MXC-B20 imhando yesimbi inoshanda zvakanyanya inoshanda pamwe chete netertiary amines kuti ikurumidze kuita pakati peisocyanates nepolyols, zvichiita kuti chigadzirwa chigadzikane nekukurumidza uye kuvandudza mashandiro azvo. Haina mercury, lead nedibutyltin, zvichiita kuti ive imwe nzira yakachengeteka uye inogara kwenguva refu pane dzimwe nzira dzechinyakare dzekugadzira tin-based catalysts.

Chii chinonzi Bismuth-Based Catalyst?

Imwe nzira yakachengeteka uye isingakuvadzi nharaunda pane dzimwe nzira dzechinyakare dzekugadzira zvinhu zvakagadzirwa netin, bismuth catalysts imhando yegel catalysts inoshanda zvakanyanya uye yakasimbiswa kuti inokurumidza kushandiswa mumhando dzakasiyana-siyana dzekushandisa, kusanganisira machira, manamati, ma sealants uye polyurethane elastomers.zvinokonzeresainoita basa guru mukuita kuti polyurethane ishande zvakanaka, ichivimbisa kuti nguva yekurapwa kwayo inononoka uye chigadzirwa chakasimba. Sezvo indasitiri yepolyurethane ichifambira mberi kune mhinduro dzisingakuvadzi nharaunda, bismuth catalysts dzakadai seMXC-B20 dzinoshandiswa zvakanyanya.

Zvinoita SeiMXC-B20Basa here?

MXC-B20 inopa kushanda kwakanaka kwazvo mu spray foam uye rigid foam systems. Kana paine doses shoma, inoita kuti front-end viscosity accumulation iwedzere, ichiwedzera reaction latency uku ichikurudzira back-end curing yakanaka. Kuenzana uku kunobvumira kutonga kukuru uye kuchinjika mukugadzirwa, nokudaro zvichiita kuti zvigadzirwa zve polyurethane zvive nezvikanganiso zvishoma uye zvemhando yepamusoro. MXC-B20 inoratidzwa nekusagadzikana kwakaderera uye kunhuhwirira kushoma kana kusina, zvichiita kuti zvive nyore kubata munzvimbo yekugadzira.

Kuenderana uye Kuchinja-chinja

MXC-B20 inoenderana nemapolyols efoam akaomarara uye akapfava uye isarudzo yakanaka kune akasiyana-siyana mashandisirwo efoam. Inogona kushandiswa zvinobudirira mufoam inochinjika, foam inochinjika ine density, foam yemicrocellular, foam inopfapfaidza uye masisitimu efoam akatsiga. Kuchinjika uku kunoita kuti vagadziri vakwanise kuita basa rakanaka muzvigadzirwa zvakasiyana-siyana, kubva pazvinhu zvinodzivirira kusvika kuzvikamu zvemotokari.

Imwe Nzira Yakachengeteka Uye Inogara Zvichienderera Mberi

Mumusika uri kuramba uchitarisa pakuchengetedza zvakatipoteredza, ma "catalysts" e "bismuth" akadai seMXC-B20 akatsiva ma "catalysts" e "tin" ne "bismuth" anochengetedza mazinga ekushanda zvakanyanya. Vagadziri vanogona kuvimba neMXC-B20 kugadzira zvigadzirwa zve polyurethane zvemhando yepamusoro kuti zvigutse kudiwa kuri kukura kwemhinduro dzakachengeteka uye dzinogara kwenguva refu.

Kuti udzidze zvakawanda nezve MXC-B20 uye kuti ingavandudza sei kugadzirwa kwe polyurethane yako, taura nesu nhasi sezvo tine nzira yakanakisisa yekugadzirisa uye timu yakazvipira kugadzirisa zvigadzirwa zve catalyst kuti zvikwanise kugadzirwa zvakanaka pamusika.
