Spray foam insulation imhando yepamusoro yeinsulation ine zvinhu zviviri: polyurethane neisocyanate. Zvikamu zviviri izvi zvinochengetwa zvakasiyana uye hazvisanganiswi kusvika panguva yekushandiswa. Kana zvasanganiswa, zvinosangana nemakemikari anoita kuti musanganiswa uwedzere zvakanyanya, zvichizadza nzvimbo dzakamanikana nenzvimbo dzakaoma kusvika. Kuwedzera uku hakungobatsiri chete insulation, asiwo kunopa simba remhepo, izvo zvinovandudza kushanda zvakanaka kwesimba.
Polyurethane ipolymer inoshandiswa zvakasiyana-siyana iyo inova hwaro hwefuro rekupfapfaidza. Ine hunhu hwakanaka hwekudzivirira kupisa uye kugona kugadzira furo rakasimba uye rinochinjika. Isocyanate ikemikari inoshanda pamwe chete nepolyurethane kugadzira chimiro chefuro. Zvinhu zviviri izvi zvinokura nekukurumidza kana zvikashandiswa kugadzira furo rakasimba rinonamira pamusoro uye rinopa kudzivirira kupisa kwakanaka, kudzivirira hunyoro uye kugara kwenguva refu.
Mhando dzeSpray Foam Insulation
Kune mhando mbiri huru dzekudzivirira furo respray dzinoshandiswa mukuvaka nekugadzira:
Furo reSpray reMasero Akavhurika: Furo iri harina kusimba zvakanyanya uye ndiro sarudzo yakakurumbira yekushandiswa mukati meimba. Rine hunhu hwekudzivirira ruzha uye rinowedzera kukura, zvichiita kuti rishande mukuzadza nzvimbo diki. Furo remaseru akavhurika rinodhura uye rinochinjika kupfuura furo remaseru akavharika.
Furo reSpray reMasero Akavharwa: Furo re spray rine mavharo rakanyanya kusimba uye rinodzivirira kupisa uye rinowanzoshandiswa pakugadzira kunze kana panodiwa kuti mvura isanyanya kunyorova. Rinoumba chipingamupinyi chisingapindi mvura uye rakakodzera kushandiswa pamatenga, pasi pevhu, nenzvimbo dzine hunyoro.
Basa reZvigadziriso zvePolyurethane
Mukugadzirwa kwespray foam insulation, polyurethane catalysts inoita basa rakakosha mukufambisa makemikari pakati pepolyurethane neisocyanate. Macatalysts aya anodzora kumhanya uye kunaka kwemaitiro efuro, zvichiita kuti furo rikure nemazvo, riporeswe zvakanaka, uye riwane hunhu hwaunoda, hwakadai sekuomarara, kuramba kupisa, uye kunamira.
Chinhu chedu chinobatsira kugadzira polyurethaneMXC-5imhando ye "tertiary amine-based foam catalyst" inokurudzira "urea" (water-isocyanate) reaction mumhando dzakasiyana-siyana dze "rigid and flexible polyurethane foam". Ndiyo "catalyst" inoshandiswa muMDI-based cast-in-place polyurethane systems", ichibatsira kuona kuti "furo" inoshanda zvakanaka uye inogara kwenguva refu.
Kushandisa polyurethane catalyst yakakodzera, yakaita seMXC-5, kunoita kuti furo rako rekupfapfaidza risvike pakukwanisa kwaro kwekudzivirira uku richivandudza kukura kwefuro, hunhu hwekupfapfaidza, uye kusimba kwechimiro. Kunyangwe uri kugadzira furo rekupfapfaidza rine maseru akavhurika kana kuti rakavharika, kusarudza furo rakakodzera kwakakosha kuti usvike pakushanda zvakanaka uye padanho rezvakatipoteredza.
Sei Uchifanira Kusarudza Chinhu Chinosimudzira Zvinhu Chakakodzera?
Vagadziri vemafuro epfapfaidzo vanofanira kusarudza chinobatsira kuti vagadzire chinodzivirira furo zvakanaka uye zvine mwero. Chinobatsira chakagadzirwa zvakanaka chinogona:
- Kuvandudza nguva yekukura kwefuro uye nguva yekurapa.
- Wedzera kunamira kune substrates dzakasiyana-siyana.
- Iva nechokwadi chekuti utsi hwakaderera uye unosangana nezvinodiwa nemitemo.
- Ipa hunyoro huri nani uye kuramba kupisa.
KuMingxu Chemicals, tinopa mhando dzakasiyana dzema "polyurethane catalysts" anoshanda zvakanyanya, akadai seMXC-5, yakagadzirirwa kushandiswa kwefuro rakaoma uye rinochinjika, zvichikubatsira kugadzirisa maitiro ako ekugadzira uye mashandiro echigadzirwa.
Kana muchida, ndapota taurai nesu kuti muwane rumwe ruzivo panhamba iyiinfo@mingxuchem.com.
