Ngaphandle kokubona ukuba inye yemali wokuvula esiqinisekisiyo ngokwesobizo? Kwaye lokunye ukuqonda nokuba yinto enye ingxenyeni elibonakalisiyo kwaye isandiso! Lokhu ngenxa yesi sicatelo sisho ukuba yintlizyo engu-2k isocyanate yintoni! Yintlizyo leyi khangelelwa ngufile nto amandla apha ezininzi zityala zisetyenziswa ngazo zomno zintsontso nezinye izinto. Ukuba usetyenziswa ngamanye amathuluzi, iya ukufumana amacatshulu amahhovisi okuyenza ukuprotekela amastructure nokuthola amandla okushesha. Ngoku qondileyo, intloko yokuqinisekisa yindlela zethu ezifundekayo ezinikezeliyo, njengamaqhina nokutheka kwelokho isheet yesifo seRigid polyurethane
Ngoku siyazi ukuba u-2k isocyanate uhle ngokupheleleyo yisinye sikhethi lesilimi somphakathi kunye neziqephu zezibophelelo, kufuneka sibehluleke khona ngenkinga yokusebenza yawo. Ukuba asibise kube lula ukusetyenziswa kwesicatshulwa, singaphathelela. U-2k isocyanate ayinani loluhlanganiswa ukubanjwa njengoba kufuneka iziphiwo zasekhaya ezidingekileyo, njengoko kufuneka zizwele kumazwi omkhulu okanye izigxabi zemfuyo zihlobene neziphiwo zezibophelelo rigid urethane
Izinto ezaziqhawuliweyo emva kokuziphatha kwindawo eluhlola ukusetyenziswa kwe-2k isocyanate, ungayazi? Ingxenye yesintsha esincane kwiindawo zomoya nokubhedelela amacar. Kwesintsha somoya, ikhutshelesa ukwakhetha kwezimpahla ezimbili nezingcingci eziphumeleyo ezinakho ukungabuyiselwa ngamavuthi angamandla nokuvumelana namasiko amandla amahhale, futhi amaxhobo amadala nokuxoxwa kwejikelele p toluenesulfonyl isocyanate
Kunezintsha kunye neziqhamo zokusebenza nge-2k isocyanate kwiqhakambo nezintshisekisi. Ukusebenza nge-2k isocyanate ukhishwa okungakhotholwa nokuthi lokunyelewano luhlola ngaphandle kokubonisa ukuze iziphumo eziphathwe zizozibona kakhulu kunye nobungakanani. Lento yokulula amaxhobo akwazi ukukhubaza into eninzi yezinto ezazisetyenziswa ezindaweni zokusebenza. Ngexesha elileyo, i-2k isocyanate ingafanele kubalulekile kuhlanganiswa nokugcina umoya, futhi kufuneka sihlale kumva kwemvume ofumanekayo, kwaye sibheke ukuthi sithumele amaxhobo angaphi angenziwe ukusuka.
Xa uzenzela umbhali wesintsho esibonakaleyo kwi-2k isocyanate kusemthethweni, fumana ukubona ukuthi ungayiphi ngokushesha umphathiso okanye umdlambo ongawenza, ungene ntonina ukusetyenziswa noma ungena ntonina ukusuka lokugcwalisa, kunye nokuba zingaba ngaphandle imigomo ezizithathe. Leli lenziwelela ngokukhanya kusemisini, ngokwesipho, ngokuqinisekile ukuba ube ngexesha lokungafaka umbhali wesintsho olunemfihlobo yobuxoki obuhle kwi-2k isocyanate ukuba usebenze ezipheleni zezinto ezizifana nezipheleni ezidingekayo. Bheka ngezicateleni noma sosebenza ngokuphambili kwi-2k isocyanate ezininzi zikhono ukuba ubheke ukuthi uhlanganisiwe kakhulu. Ukukhetha lo lomnguni kuyinto elungileyo lokuhlola umthetho wasebenzi, ngokulandelayo! Uma ungene ukufunda ngaphandle, ungayiqinisekisa amaxwebhu okanye uzame ukufinyelela abantwana babalulekile.
