Ifomu yepolyurethane enge-isocyanate yiindlela elinenzeka lokuphakamisa amandla ahlola kwiqhutywa nezimo zokubulawa nokuthuthukiswa. Ifomu ifunyenwa ngokuba kuhlela izindlela ezikhathalekileyo nokusebenza ngenxa yalokho. Isifundazwe esisodwa sasinye singaphambili kakhulu lapho, SANYING, bengayiqhuba lokuncedeka olungumthombo omncane wakho. Nangona ndizobizo ngazo ngalokhu ifomu kunye nokuba ungene ngayo ngcono kwindawo yokubulawa.
Ifomu yesiPolyurethane engenani isocyanate seleliphindaphinda ukusetyenziswa ngemva kokucabanga okuningi nelinyeleyo. Isebenzisa ubungakanani obusha ukuba zizamele izithelo zezilimi ezidingekayo ezinamandla ngaphandle kwezilimi ezincedwayo ezinamandla ezinamandla ezininzi zokugcina iisocyanate. Ngoku izokhayanate ziyi- zingapheleleyo kuzo abantu kunye nokulandelana nokulula kwenzeleleyo lokuhlola, ukuba akukho lezilimi eziningi zihlanganise ukuba ifomu lenziwe ngcono kwindawo yokubulawa. Izibonelo ezinhle zingaba abanye abasebenzela lofoke kunye nabantu abaza kuhamba kuzo izindlela ezizenzakalo ezizosetshenziswa naye.
Tshintsha, kungenzeka ukuba kukho iminikelo engqongeyo yokusetyenziswa kwe-polyurethane foam engaphandle kwe-isocyanate ekwakheni. Okokuqala nokokuphela, kusebenza kancinci ngoba ayingeki ukuphuma kumefu ethile wima xa kusetyenziswa. Lokhu kwenza kube lula kakhulu ezindaweni ezingenazo umoya oshushu okanye ebandleni bempilo okanye emakhaya. Abasebenzi nabangcono bazi ukuba basebenzisa into engasixhoshelwa kuzo iimpawu zempilo yabo. Non-isocyanate polyurethane foam nayo inobuthwalwa bakanani nobunzima obukhulu. Iphila amakhaya anesibane kumhla wosuku kwaye ibanda kumhla wophuthu, njengoko ikunceda intengo yemali kwizikhamelo zenjongo. Ngamanye amazwi, lo foam ube yinxalenye eqinileyo enkqonkqothene yokulula isantya phakathi kwamakhaya. Inkanyisa nesimanga futhi, oko kuyinkcazelo eyodwa evela embangalini apho kungafika kumthuthlwa okanye apho kukhona ubuchwepheshe bukhulu. Amakhaya abasebenzisa lo foam abanalo inkcazelo encinane yokuba ziphinde zibukeke ngomoya okanye zisahluleke.
Le fotho lesiSANYING luyenza uphawu olungileyo lokusetshenziswa kwisebe lokubhedlela. Umthengi omncane (ngishumi ne 5 kg) owabhekisekelayo kunye nokusetshenziswa angaphambili kwisebe lokubhedlela, ulula isikhatsi kunye nemali. Ngemuva kokuthi yabelwe ngexhasi elinekhwezi, abasebenzisi bayakhetha phambi kwezinto ezincedayo kunye nokusetshenziswa kwisebe lokubhedlela ngokupheleleyo. Kwisihlobo sokuqala ifomu yesi polyurethane esifakweyo ukusebenza kwaye ukusetyenziswa kuhluke kakhulu ukuthi izintsi zakho zisisebenzise ngokubanzi kwaye zisisebenza ngokupheleleyo.
Umgwa wokuphucula polyurethane engasisaneni isocyanate nge-SANYING ifane kakhulu ngokuba kusetyenziswa, ungene ukwazi ukusetshenziswa kumanye amaphutha ngokulandelana nokubhedliselela. Ungenayo ukusetshenziswa njengomsebenzi wesiqephu lokusebenzisa ukufinyelela amagwenxa okanye ukufakelwa imigquqambo. Izicatshulwa eziningi zingezantsi ziyenza ukuba yile yi-material elithile kwi-mphathiso yobukhwebo obunene kunye nokuthi kukhulu. Ngoko kumboniso kwesizinda sikuhle ukuza kusetyenziswa esetshenziswa ngokuba le matrikhi angayibona ngemva kokuba kungcono.
Iphofo ye-polyurethane engaphandle kwe-isocyanate ibuyela ekuphuculeni kwinkamva yesakhiwo ngamaxesha amaninzi apho amanye wazo nguqu ezingenelo zalo. Kukhuselekile kumsebenzi, kumhlonipha umntu, kunamandla kwaye inokusetyenziswa ngendlela eyahlukene. Ngoko ke zonke iimpawu ezilungileyo isibhopho esisodwa sokuqinisekisa abasetyenziswa kunye nezikhankaso zifuneka umgwa wakhe wezisebenziselela. Zaziwa ukuba ngokwandlela zikuphila indlela yakho kunye nokuba zihlinzelela konke umuntu.
