Zombiniiipaneli zokugcina ezibandayo ze-polyurethanekwayei-polyurethane sprayukugcinwa okubandayo sebenzisa i-polyurethane efanayo.Umahluko phakathi kwezi zibini ulele kwisakhiwo kunye nendlela yokwakha.Iphaneli ye-polyurethane yokugcina ebandayo ehlanganisiweyo kunye ne-polyurethane njengeyona nto ingundoqo yenziwe ngamacwecwe entsimbi angaphezulu nasezantsi kunye ne-polyurethane enegwebu eliphakathi.I-polyurethane ebandayo yokugcina umzobo wokutshiza kukutshiza i-polyurethane foam kwindawo yangaphakathi yesakhiwo.Emva kokubunjwa, inokusetyenziswa ngokuthe ngqo njengoluhlu lwe-insulating okanye umaleko wangaphandle.Gubungela ngephepha lesinyithi ngaphambi kokusetyenziswa.

Umahluko phakathi kwe-polyurethane yokutshiza ukugcinwa okubandayo kunyeibhodi yokugcina ebandayo:
1. Ibhodi yokugcina ebandayo inezinto ezifanayo kunye ne-thermal insulation enamandla.Ngenxa yokutshiza ngesandla, akunakuphepheka ukuba ukuxinana okungalinganiyo kuya kwenzeka.
2. Ibhodi yokugcina ebandayo yenziwa kwifektri, isantya sokwakha sikhawuleza, ixesha lokwakha lifutshane, kwaye ukwakhiwa kokutshiza kuyinkimbinkimbi kwaye kuthatha ixesha.
3. Kuphela iiphaneli zefriji ezinoxande kunye no-L ezinokuveliswa.Ukuba isakhiwo sakho sefriji sinamathambeka okanye ii-arcs, unokwenza iipaneli ezinkulu zokugcina i-thermal ukusika kwisayithi okanye ukunciphisa ubukhulu befriji.
4. Ibhodi yokugcina ebandayo inokubonakala kakuhle, kulula ukuyiphatha nokugcina, ingasetyenziselwa ukucoca nokucoca, kwaye ihlangabezana neemfuno zokucoceka kokutya kwaseTshayina.I-thermal insulation layer eyenziwa yi-spray painting ye-polyurethane yokugcina ebandayo ibonakaliswe emoyeni, kwaye umphezulu awugudi, ongenakunceda ukucoca, kwaye izinto eziwayo zinokungcolisa ukutya ngokulula.Nokuba igutyungelwe ngepleyiti yentsimbi, ipleyiti edibeneyo yokugcina ebandayo ayilula ukuyisebenzisa kwaye iyasebenza.
5. Isitshizi esibandayo se-polyurethane singasetyenziselwa ukusondeza i-insulation kufuphi nengaphakathi lesakhiwo, kodwa kuphela ukuba iplanti yefriji yakhiwe ngaphakathi, okanye ukuba isakhiwo sobunjineli boluntu sisetyenziswe kwiprojekthi yefriji yangaphandle.Ngokuqhelekileyo, ii-refractories ezipeyintiweyo azisebenzi kwaye azibizi njengeepaneli zefriji, ngoko ke iiprojekthi zefriji zanamhlanje zixhomekeke kwiipaneli ezifanelekileyo kunye nezisebenzayo.Nangona kunjalo, inzuzo yepeyinti yokutshiza kukuba abathengi abaninzi bakhetha ipeyinti yokutshiza i-polyurethane ngenxa yendawo enkulu yokupholisa kunye nokusetyenziswa ngokupheleleyo kwendawo yokwakha.
