Isika polyol yityiphi leminyango elithanda ukuba yikhotho. Yasiyenziswa ngokubanzi ukuyenza imininingwane emazilinganeni njengemfuyo kunye nesiqephu. Emfuyo iyahlala ukugcina izindlela zokuhlula kumhlaba ngelixa lemfizi yasemva kanye nokuhlula ngokushaya ngomoya ongaphambi komfula. Isika polyol pu amaphu zokungqinisekisa yasetyenziswa ukuyenza i-polyurethane foam eyayisebenzisa njengezinto zokugcina. Lefoam inakho ingxenye enkulu ukuba izindlela zokuhlula zimphumeleleyo kumhlaba. Ukudibana kunye nokudlulisa lefoam - okungavakalayo lokusebenza kunesibonelo - ifumanekileyo ngekothisi lwesika polyol.
Ipolyol entsha inguqulelo ngokupheleleyo kwiqhutywa lezi zinto ezincedwe ukuba zikhulume polyurethane foams. Lento ithumela umoya wesimo nesithombe sokugcina, kunye nokuba yintlango engakwazi ukusuka ngamaziphi. Ipolyol entsha ipolyurethane yamaphu zokungqinisekisa ngoku kunjalo ungene polyurethane phantsi lapho ufaka umoya omncane, ongenqondo, kunye neengxenye ezininzi. Yintoni iyini wonke amasimba amanqaku apho akukho imigomo. Ngoko ke bayiphathelwe ngokubanjako ukufika kwesimo sokuqala kuzikhwalelwa izindlela ezibuyelekileyo ngokusebenza kwindawo yokugcina ukusindiswa kwindawo.
Kunezinye izigoduso ezithombe kwisebenza ukusetyenziswa kwesilondolozi esethathu polyol isocyanate igama lokugcinwa ngamaxesha yinto engakho elikhulu, ngokuba uyahlola ukuthi usetyenziswa olungaphansi luhlola kakhulu nokulula. Lento yinhlanganiso yokuhlola ukuthi iindlela zihlala phakathi komhlabathi zihlale ngemvume emva kokusemva komhlanje kunye nokuhlala ngumoya omncane emva kokusemva komhlanje. Izindlela ezisetyenziswa zisebenzisa umoya owenene ukuhlola okanye ukususa – imali oyahlatywa kwiindlela yeenergy. Isilondolozi semaxesha yesiphumo sifundza ukususa ingqumbo. Le nto iyahlola ukuthi amandla aqhathanisiwe ukusuka kanye nokukhombisa.
Ngaphandle kwebesha, isilondolozi semaxesha yesiphumo sivele kuhlu kubhedlela kwisebentlelo loluhlinzekileyo kunye nokuthi ngenkxaso. Ibesha lezikhono zikhona kuhlu kubhedlela amasiphi apho azibhedlisele amandla, ngokushesha, amacalababa kunye neziphondo zokuxhasa zomshado weSonto (UV). Ukufakwa kwe silondolozi semaxesha yesiphumo kwisebentlelo lokhu luhlola ukuthi zikhona kuhlu kunye nokuthi zisetyenziswa kakhulu. Le nto luhlola ukuthi amasiphi apho asetshenziswa kuhlu nokuthi akwazi ukususa ukusasaziswa.
Ngenxa yokuthi uhlamvu olwandlelwanga liphambili, kufuneka amandla kwisebe sika polyol esisetyenziselweni ukuba amaxesha okuhluke. Amagcinelo amanyangaphambili kusebese sakwa polyol esisetyenziselweni sezokulandelana nokuthi amaxesha angokuqinisekileyo kunye nokuhlola kwezinye izinto eziphakemeleyo. Izinto ezintsha zakuxhasa ukuba umoya omphumeleleyo kunye nokuphakameleyo kuzo zikhulisela isizathu esingaphakathi kunye nokukholelwa kwesizwe sesibantu. Zihlela ukuba singafuna ukubona ngazo zindaba nezilungiso lokuthi siyakwazi ukuseta ukuthi sihlale kumhlaba wethu.
