Mamiriro aripo pari zvino ekushandisa tekinoroji yekudzivirira furo respray
Zvinhu zvinodzivirira furo repolyurethane spray zvave tekinoroji huru yemapurojekiti emazuva ano ekuchengetedza simba muzvivakwa. Nekushanda kwayo kwakanaka kwekudzivirira kupisa uye hunhu hwayo hwekuvaka husina musono, ine chinzvimbo chakakosha mumusika wepasi rose wekudzivirira kupisa muzvivakwa. Iyi tekinoroji yekugadzira panzvimbo inopfapfaidza musanganiswa weisocyanate nepolyol zvakananga pamusoro pe substrate, uye inokurumidza kuita chiito che catalyst kugadzira chimiro chefuro remasero akavharwa kana kuti rakavhurika kuti iwane mhedzisiro yakanaka yekudzivirira kupisa.
Furo repurasitiki rakavharirwa rave chinhu chinodiwa pakudzivirira madziro ekunze, matenga uye nzvimbo inotonhorera nekuda kwekushanda kwayo kwakanaka kwekudzivirira kupisa (kupisa kunopfuta 0.020-0.028W/(m·K)) uye hunhu hwekusimbisa chimiro. Chinokosha pakuita izvi zvakanaka ndechekudzora system ye catalyst ye trimerization reaction ye polyisocyanurate.
Kubudirira kwehunyanzvi hweMXC-TMAkataviridzi
MXC-TMA catalyst chizvarwa chitsva che trimerization catalyst chakagadzirwa zvakanangana ne spray foam. Fomura yayo itsva inogadzirisa matambudziko mazhinji ehunyanzvi ema catalysts echinyakare ane potassium panguva yekuvaka. Ichi chigadzirwa chemvura chinopenya chisina ruvara kusvika cheyero yakapfava chinoita kuti polyurethane reaction kinetics ive yakarongeka kuburikidza nekuumbwa kwayo kwakasiyana kwemakemikari.
Panyaya yekudzora mashandiro emushonga, MXC-TMA inopa mukana wekukwira wakafanana uye unodzoreka, zvichideredza kudzika kwemushonga panguva yekuvaka nekupfapfaidza. Zvikamu zvayo zvakasiyana zvinogadzirisa mashandiro emushonga nejelling, zvichidzivirira kugadzirwa kwezvikanganiso pamusoro, ukuwo zvichivandudza kumhanya kwemushonga uye zvichipfupisa zvakanyanya nguva yekuvaka.
Kuvandudzwa kwekuyerera kwemvura ndeimwe mukana mukuru weMXC-TMA. Chigadzirwa ichi chinogona kuvandudza zvakanyanya hunhu hwekuyerera kwemafomula ehuwandu hwakasimba uye kuwana kupararira kwakafanana kwefuro, izvo zvinonyanya kukodzera kugadzirwa kwekupfapfaidza panzvimbo dzakaoma dzejometri. Kana zvichienzaniswa nemidziyo yechinyakare ine potassium-based catalysts, MXC-TMA inogona kuramba ichiita basa rakanaka munzvimbo dzakaderera dzekupisa, zvichiwedzera zvakanyanya huwandu hwekushandiswa kwekupisa kwekuvaka.
Nheyo dzehunyanzvi uye zvakanakira mashandiro
MXC-TMAInokurudzira trimerization reaction ye isocyanates kuti igadzire chimiro che isocyanurate ring chakasimba. Chimiro ichi chakakosha chemakemikari chinopa zvinhu zvefuro zvakanakira zvitatu zvikuru: kugadzikana kwekupisa kwakanyanya, tembiricha yekuora inogona kuwedzerwa ne30-50℃; kuramba moto kwakanyanya, indekisi yeokisijeni inogona kusvika 26-28; kugadzikana kwakanaka kwehukuru, chiyero chekuchinja kwevhoriyamu chinodzorwa mukati me1%.
Mukushandisa kwatinoita, tinokurudzira kushandisa MXC-TMA pamwe chete neamine catalysts, nechikamu chinodzorwa pa30-50% yehuwandu hwe catalyst. Chigadzirwa ichi chine tembiricha yakakura yekushanda (15-35℃), chinoenderana nemhando dzakasiyana dzemafuro akadai seHFC-245fa neHFO-1234ze, uye chinogona kushandiswa pamwe chete nepolyether/polyester polyols dzakawanda uye zvinoderedza moto.
Rutsigiro rwehunyanzvi hwehunyanzvi uye vimbiso yebasa
Tinopa rutsigiro rwakakwana rwehunyanzvi kune vagadziri vepasi rose vema spray foam nemakambani ekuvaka, kusanganisira masevhisi ekuongorora marabhoritari, gwara rekugadzirisa mitsetse yekugadzira uye mhinduro dzekuvandudza dzakagadzirwa. Chikwata chehunyanzvi chehunyanzvi chinogona kupa mhinduro dzemhando yepamusoro dze catalyst system zvichienderana nemidziyo chaiyo yemutengi nemamiriro ekushanda.
Panyaya yehurongwa hwekuvimbisa mhando, tinonyatso tevedzera mitemo yekugadzira yakasimbiswa neISO 9001 kuitira kuti tive nechokwadi chekuti kugadzikana kwezvigadzirwa kunopfuura 99%. Network yakakwana yepasi rose inogona kusangana nezvinodiwa nevatengi nekukurumidza uye kuona kufambira mberi kwekuvakwa kweprojekiti.
Wana rutsigiro rwenyanzvi
Tinokoka nemwoyo wese vadyidzani vedu muminda yakasiyana-siyana kuti vaone kushanda kwakanaka kweMXC-TMA catalyst. Kana muchida ruzivo rwakadzama rwehunyanzvi kana kunyorera kuongororwa kwemuenzaniso mahara, ndapota taurai nechikwata chedu chehunyanzvi nenzira dzinotevera:

Kusarudza MXC-TMA catalyst hakungogone chete kuvandudza kunaka kwekuvaka uye kushanda zvakanaka kwespray furo, asiwo danho rakakosha rekugadzirisa zvivakwa zvine girini. Ngatishandei pamwe chete kukurudzira kuvandudzwa kwehunyanzvi hwekudzivirira kupisa uye kuvaka nharaunda yekuvaka inogara kwenguva refu.
