Foam yepolyurethane inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana nekuda kwekushanda kwayo kwakasiyana-siyana, hunhu hwayo hwekudzivirira kupisa uye hunhu hwemaumbirwo ayo. Hunhu hwefoam hunogona kusiyana zvakanyanya zvichienderana nechimiro chemasero avo, izvo zvinogona kukamurwa kuita foam dzemasero akavhurika kana foam dzemasero akavharika. Sarudzo yezvinokonzera zvinoshandiswa mukugadzira foam yepolyurethane ine basa rakakosha mukuona hunhu hwefoam, kusanganisira kuwanda kwayo, kuchinjika kwayo, uye kunhuhwirira kwayo. Muchinyorwa chino, tichaongorora mutsauko uripo pakati pefoam dzemasero akavhurika nemasero akavharika uye toongorora kuti zvinokonzera polyurethane catalysts zvakanongedzwa zvakaita seMXC-T neMXC-37 zvinogona kushandiswa sei mukugadzira.
Kunzwisisa Mafuro Akavhurika Neakavharwa
Foam Yakavhurika
Furo remasero akavhurika rinozivikanwa nemasero efuro akabatana kuti agadzire magadzirirwo akaita sesponji. Furo iri rinowanzo kuve rakareruka, rinochinjika, uye rine maburi akawanda, zvichikonzera kuti rikwanise kupinza ruzha zvakanaka uye kudzivirira ruzha. Furo remasero akavhurika rinowanzoshandiswa muzvinhu zvinoda kucheneswa, zvakaita sefenicha, zvigaro zvemotokari, uye kudzivirira ruzha. Hunhu hwaro hukuru ndehwekurema kwakaderera, kuchinjika kwakanyanya, kushanda zvakanaka kwekudzivirira ruzha uye kupisa, uye kupinza mhepo zvakanaka.
Foam Yemasero Akavharwa
Kusiyana neizvi, chimiro chefuro rine masero akavharwa chakasimba uye chakavharwa, zvichidzivirira kuyerera kwemhepo kana mvura. Furo racho rakakora, rakaomarara uye rakadzivirirwa zviri nani kubva muhunyoro. Furo rine masero akavharwa rakanakira kushandiswa kunoda kugara kwenguva refu uye kuramba mvura, zvakaita sekuputira zvivakwa, furo respray rezvivakwa zvinoshandisa simba shoma, uye dashboard dzemotokari. Hunhu hwaro hukuru ndehwekuwanda kwesimba, kuomarara kwakanyanya, hunhu hwakanaka hwekudzivirira kupisa (kupisa, kuramba hunyoro), kuramba mvura uye kugara kwenguva refu.
Basa rePolyurethane Catalysts mukugadzirwa kweFoam
Zvishandiso zvepolyurethane zvinoita basa rakakosha mukugadzirwa kwefuro nekubatsira kuti pave nekuita kwemakemikari pakati pemapolyol (kazhinji anobva mumiti kana peturu) uye isocyanates kuti zvigadzire mapolyurethane. Zvichienderana nehunhu hwefuro hwaunoda, hwakadai sekuwanda, kuchinjika, uye hwema, zvinoshandiswa zvakasiyana-siyana.
MaCatalyst akadai seMXC-T neMXC-37 ane zvakanakira chaizvo pakugadzira furo remasero akavhurika nemasero akavharika. Ngatinyatsoongororai nzvimbo dzinoshandiswa uye zvakanakira maCatalyst maviri aya.
MXC-T (CAS 2212-32-0)mukugadzirwa kweFoam
MXC-T, inozivikanwawo seTMAEA, imushonga unoshanda zvakanaka, usina amine unoburitsa zvinhu zvino ...
Kushandiswa muFuramu Dzakavhurika neDzakavharwa
MXC-T inoshanda zvakanyanya mukushandiswa kusingadi hwema hushoma uye inoshanda zvakanaka mukugadzirisa hunhu. Basa rayo rekugadzirisa hunhu rinokurudzira kuita kweurea (water-isocyanate), iyo inowanzoita nepolymer matrix nekuda kweboka rayo re active hydroxyl. Ndosaka MXC-T ichinyanya kushandiswa mu:
- Kudzivirira Furo reSpray: MXC-T inoita kuti furo rekudzivirira rive nechimiro chakafanana uye risina kunhuhwirira, zvichiita kuti rive rakakodzera kushandiswa mukudzivirira kupisa mudzimba nemabhizimisi.
- Madhibhodhi eMotokari: Kunhuhwirira kushoma uye kutsetseka kweMXC-T kunoita kuti ive sarudzo inofarirwa mukushandiswa kwefoam yemotokari, senge pamadashboard nezvimwe zvinhu zvemukati.
MXC-37 (CAS 1704-62-7)mukugadzirwa kweFoam
MXC-37, kana kuti DMAEE, chimwe chinhu chinobatsira amine chisina kuburitsa mweya, chine hwema hushoma uye chinoshanda zvakanyanya pakuburitsa furo. Chakakodzera zvikuru kune mafomu anoda mvura yakawanda uye chinowanzo shandiswa mukugadzira mafoam epurasitiki ane porous polyurethane (SPF) ane porous density shoma. Iyi catalyst yakakodzera kugadzira mafoam ane porous yakawanda uye ane chimiro chemasero chakafanana, zvichiita kuti ishande mukushandiswa kwakasiyana-siyana uko hunhu hwakadaro hunodiwa.
Kushandiswa muFuramu Dzakavhurika neDzakavharwa
MXC-37 inozivikanwa nekukwanisa kwayo kuderedza hwema hweamine hunowanzoonekwa mumafuro epolyurethane, zvichiita kuti ive sarudzo yakakura kune nzvimbo dzine hutachiona hwakadai se:
- Foam yeSpray ine Density Yakaderera (SPF): MXC-37 inoshandiswa zvakanyanya mukushandisa furo respray rine huwandu hushoma hwemvura, uye kunhuhwirira kushoma kunokosha. Izvi zvinosanganisira kushandiswa mukudzivirira kupisa, denga, uye masisitimu emadziro.
- Furo reMicrocellular: MXC-37 inogona kushandiswa kugadzira furo re microcellular, rinowanzoshandiswa mukupakata, zvikamu zvemotokari nezvimwe zvinoshandiswa zvinoda furo rakareruka, rinochinjika, pamwe chete nefuro rakapfava uye elastomers uko kuchinjika nekugara kwenguva refu zviri zvinhu zvakakosha.
- Kurongedza Foam Yakaomarara: Mukushandisa pakurongedza, kunyanya kana paine hunhu hwakareruka uye hwekuputira hunodiwa, MXC-37 inoshanda mukudzora huwandu hwefuro uye kusimudzira chimiro chefuro.
MXC-37 inogona kushandiswa sechinhu chikuru chinobatsira kana kuti sechinhu chinobatsirawo, kunyanya kana ikasanganiswa nezvimwe zvinhu zvinoita kuti pave nefuro uye kuderedza kudiwa kwezvimwe zvinhu zvinoita kuti pave nefuro.
Mhedziso
Zvinhu zvinokonzeresa polyurethanezvakaita seMXC-T neMXC-37 zvakakosha pakugadzira furo rakavhurika nerakavharwa, zvichibatsira vagadziri kuwana hunhu hwefuro hwavanoda uku vachideredza zvinhu zvinokuvadza zvakaita sekunhuhwirira uye kuburitswa kwemhepo. Nekusarudza chinhu chakakodzera chemhando yefuro, vagadziri vanogona kuvandudza mashandiro uye kugara kwenguva refu kwezvigadzirwa zvavo.
