Kuvaka Mapaneru eSandwich uye Basa rePolyurethane Catalysts

Nhanganyaya yekuvaka Sandwich Panel

Mapaneru esandwich imhando yekuvaka inozivikanwa uye inoshandiswa zvakasiyana-siyana inoshandiswa mukuvaka zvivakwa zvekugara nezvekutengeserana. Ane mativi maviri ekunze, anowanzo gadzirwa nesimbi dzakadai sesimbi kana aruminiyamu, uye chinhu chikuru, chinowanzo gadzirwa nefuro repolyurethane (PU) kana mineral wool. Chimiro ichi chine mativi akawanda chinopa kudziya kwakanaka, simba uye kugara kwenguva refu ukuwo chichichengetedza chimiro chakareruka. Kusanganiswa kwezvinhu izvi kunopa kudziya kwakanyanya, kudziya uye hunhu hwemakanika hwakawedzerwa, zvichiita kuti mapaneru esandwich ave sarudzo yakakura yekuvhara denga nemadziro uye kudziya muzvivakwa zvemaindasitiri, matura nenzvimbo dzekuchengetera zvinhu zvinotonhora.

Magadzirirwo akasiyana emapaneru esandwich anoagonesa kutsungirira mamiriro ekunze akaoma kubva pakupisa kwakanyanya kusvika kumhepo ine simba ukuwo achichengetedza simba rakawanda. Zvinhu zvepolyurethane zvine hunhu hwakanaka hwekudzivirira kupisa, izvo zvinobatsira zvikuru pakushanda kwesimba rechivako. Zvisinei, kuwana mabhenefiti aya kunoenderana zvakanyanya nemaitiro emakemikari uye maitiro anobatanidzwa mukugadzirwa kwemapaneru, kunyanya kushandiswa kwezvinokonzeresa polyurethane.

Polyurethane mukuvaka Sandwich Panel

Polyurethane yave chinhu chinodiwa zvikuru pakuisa sandwich board core layers nekuda kwehunhu hwayo hwakanaka hwekudziisa kupisa uye kuchinjika kwayo pakushandisa. Polyurethane pamwe chete neisocyanate, polyols, uye catalysts zvinogadzira furo rakasimba repolyurethane rinopinzwa mukati mesandwich plate pakati pezvikamu zviviri zvekunze. Furo rinokura uye rinokuvadza, richigadzira core layer yakareruka asi yakasimba ine kudzivirira kupisa kwakanyanya.

Zvisinei, kuti uwane hunhu hwaunoda hwechigadzirwa chefuro chekupedzisira, senge density chaiyo, thermal conductivity, uye curving rate, ma catalysts anoita basa rakakosha mukudzora makemikari panguva yekuburitsa furo. Kusarudzwa kwe catalyst kunogona kukanganisa zvakanyanya hunhu hwekupedzisira hwefuro, kusanganisira nguva yaro yekupisa, reaction rate, uye mhando yepaneru rapera.

Basa reCatalysts mukugadzirwa kwePolyurethane Foam

MaCatalyst anoshandiswa mukugadzira masandwich panels akakosha pakugadzirisa hunhu hwepolyurethane foam kuti ienderane nezvinodiwa zvega zvega. Macatalyst maviri anowanzoshandiswa mukugadzira masandwich plates ndiMXC-41 neMXC-BDMA.

1. MXC-41 Chinosimudzira

MXC-41 imhando ye polyurethane foam catalyst inoshanda zvakanaka, inonyanya kukodzera ma sandwich plates. Imhando ye tertiary amine catalyst inobatsira kuti isocyanate nema polyols zvishande zvakanaka, zvichiita kuti nzira yekupisa ishande zvakanaka. Iyi catalyst inobatsira kuti pave nekuenzana kwakanaka pakati pekuwedzera kwefuro nekupisa, zvichiita kuti furo riwane huremu hwakakodzera uye hune simba pasina kukanganisa hunhu hwekupisa. Iyo MXC-41 inoshandiswa mumashandisirwo anodiwa apo kudzorwa kwakanyatsojeka kwehuwandu hwefuro uye kumhanya kwekupisa kunodiwa, senge pakugadzira mapaneru e sandwich emhando yepamusoro ekuvaka chivako.

2. MXC-BDMA Chinosimudzira

MXC-BDMA, chinhu chinobatsira kugadzira furo re polyurethane rema sandwich panels. Sechinobatsira kugadzira furo risingasvibisi uye risingakuvadzi nharaunda, MXC-BDMA inokurudzira kuita kwefuro zvinobudirira uku ichideredza mukana wekuti furo re volatile organic compound (VOC) risvibiswe. Chinobatsira kugadzira furo rinogara kwenguva refu, zvichiita kuti chigadzirwa chekupedzisira chigare kwenguva refu. Kushandiswa kweMXC-BDMA muma sandwich panels kunobatsira kuti zvinhu zvekuvaka zvigare kwenguva refu nekuderedza kabhoni uye kuvandudza mhepo panguva yekugadzira.

Zvese MXC-41 neMXC-BDMA zvinoenderana nemhando dzakasiyana dzema polyol systems uye zvine simba rekugadzira furo rinosvika padanho rekushanda kwakasimba pakuvaka. Izvi zvinoita kuti furo rekupedzisira re polyurethane rinoshandiswa muma sandwich panels rive nekupisa kwekupisa kwenguva refu, simba remakanika uye kuramba hunyoro.

Mabhenefiti ekushandisa Polyurethane Catalysts muSandwich Panels

Kushandiswa kwe polyurethane catalysts mukuvaka sandwich panel kune zvakanakira zvakawanda zvakakosha:

1. Hunhu Hwakanaka hweFoam

Chinhu chinobatsira kugadzira furo repolyurethane remhando yepamusoro rine simba rekudzivirira kupisa, huremu, uye hunhu hwemakanika hunodiwa. Izvi zvinoguma nemapaneru esandwich asingashandise simba zvakanyanya, anogara kwenguva refu, uye asingakuvadzi kubvaruka.

2. Kurapa Nokukurumidza uye Kubudirira Kwekugadzira

Zvinokonzera simba zvakaita seMXC-41 neMXC-BDMA zvinoita kuti nguva yekupisa irambe ichikwira, izvo zvinoita kuti kugadzirwa kubudirire. Izvi zvakakosha zvikuru mukugadzirwa kwezvinhu zvakawanda uko nguva nekushanda kwazvo zviri zvinhu zvakakosha.

3. Kuchengetedza Zvakatipoteredza

Zvinhu zvinogadzira macatalyst zvakaita seMXC-BDMA, izvo zvinoburitsa utsi hushoma uye zvine hushamwari kune nharaunda, zvinobatsira mukusimudzira kugadzirwa kwemasandwich panel. Nekuderedza kuburitswa kweVOC, zvinhu izvi zvinobatsira kuderedza kukanganiswa kwezvinhu zvekuvaka nenharaunda.

4. Kugadzirisa Mashandisirwo Akananga

Zvishandiso zvakasiyana-siyana zvinogona kushandiswa kugadzirisa hunhu hwefuro kuti zvienderane nezvinodiwa zvemapurojekiti akasiyana ekuvaka. Ingava yekuvandudza insulation, kuramba hunyoro kana simba remakanika, zvishandiso zvepolyurethane zvinogona kubatsira vagadziri kugadzira mapaneru esandwich akagadzirwa anoshanda zvakanaka mumamiriro akasiyana-siyana ezvakatipoteredza.

Mhedziso

Panel yesandwich chikamu chakakosha chekuvaka kwemazuva ano, inova chinhu chekuvaka chinochengetedza simba, chinogara kwenguva refu uye chinoshandiswa zvakasiyana-siyana. Kushandiswa kwepolyurethane foam mumapanel esandwich kunoita kuti asvike padanho rakasimba rekudzivirira kupisa uye mashandiro emakanika anodiwa neindasitiri yekuvaka. Zvishandiso zvepolyurethane zvakaita seMXC-41 neMXC-BDMA zvinoita basa rakakosha mukuvandudza maitiro ekugadzira uye kuona kuti chigadzirwa chekupedzisira chinogara kwenguva refu. Nekuvandudzwa kuri kuitwa kwezvishandiso zvinobudirira uye zvine hushamwari kune nharaunda, ramangwana rekuvaka panel yesandwich rinopenya zvakanyanya, zvichiita kuti mashandiro ave nani uye kuderedza kukanganisa kwezvakatipoteredza.
