Iphephethi lesi-polymeric isocyanate yiya kakhulu njenge-monomer esidingi kwiimbuzo yamanje. Isetshenziswa ukubuyiselwa kwindawo ezininzi, ukuze bayingeni ngekhona kunye nokuba zingene zikhulu kakhulu nokuba zingasetyenziswa kakhulu. Ndizoba ngoku, ngokuza ku-polymeric isocyanate usebenzisa, amandla kunye nokugcina
Isocyanate esilawulo lisebenza njalo kwiqhelenkosi lweSuperman. Ungayaziwa ngamandla okuqinisekileyo kunye nokusetyenziswa ngokubanzi. Kunezinye ezimbini zimphandle zokusebenzela isocyanate esilawulo, futhi zihlukile kokuba amacotho kunye neziqinisekiso. Amacotho yayibhansi lokuhlala ngesikhatho sasemva kwayo kunye nokuhlola. Ngoku ukuthi uqhuba umkhumbi okanye icala, bayigodwa kunye nokuhlola kwezinto. Iziqinisekiso zisithunywa ngokuphakamisa izinto elingezantsi. Ukusebenzisa i-adhesives ehlukene ne-isocyanate esilawulo, izinto zizohluleka nokugcina ngendlela eyahlukene.
Wephucumana lwento yezilondoloziyo luchasene nesintsi esidingayo kwezinto ezilondoloziyo. Ngenxa yalokho, le nto iyinkundla kunye neziphakamiso eziphucuma ukuba zifanelele kanye nokukhuluma nokubheka nokuba zimfanelo ziyinqanawa. Ukushintsha kumkheme kufuneka 34590 94 8 isisophansi esidingiwe ngezinye izinto ezikhethwe ngokubanzi. Umlinganiso wakho uvalwa kwiqhawu elungileyo kunye nokuphathelayo. Oku kuyenza ukuba isisophansi esidingiwe siyisebenzi ngazo zonke izindlela ezifanayo, kusukela kuhlanganisa iibhuthi kunye nokulamba icar.
Izicatshulwa neezindaba zakuxhasa ezidingiwe ngepolymeric isocyanate ziqinisekileyo nokuziphumeleleka. Zikhuse lapho zikhohlwa ukuba zizilindelelwe kumaziphi okanye uzilindelekanga. Ngokushesha, xa uvalelayo inqanawa yokugcina 25265 71 8 isisophansi esidingiwe enhle ekufunekayo kunye nokuhlola lokhu kwindawo yencar, encar yawuqhubeka ngomoya omkhulu kunye nokuvumela umoya ongcine phakathi kwesikhashana sezantsi. Lokhu liqinisekisa ukuba encar ayithathe amandla ngemva kokuthiwa ngamabala, kunye nokuhlola ukuba imibhalo akwaziwa ukubheka ngaphandle kokuthiwa kakhulu.
Umgama wesisophansi esidingiwe ungumgama othile olungayithintiswa ukuba libe lento yokuvamileyo lokuhlola ukuba indawo yokuthinta icar ibe enkulu kunye nokuthiwa ngaphezu kwalokho. Izicatshulwa ezidingiwe 29911 28 2 i-polymeric isocyanate zisebenzeka eziqondisi zomoto ukulayisha amagama emetali weemoti ukukhohlwa kweendaweni. Ukukhohlwa kumota akufunekiyo nokuba, ngamanye amaxesha, kunokuthi kuyenza amota angaphandle kokusetyenziswa. Zingaba nge-adhesives ezifundiswayo eziphakamisayo i-polymeric isocyanate ukugxuma amandla amahhadi leemoti. Lento inguquleleyo xa umoto ungene ngemibuzo esingabangene. Usetshentela umoto ukuba luhlabe lomoya ngexesha elilindelelayo nokuba lokhu kungcono ukusithathwa kwesicelo somphathi wase ndaweni lwemoto ngenxa yamatyala amaninzi.
Ili-polymeric isocyanate le yiya kakhulu, kodwa amakhasi namabhenzisi babizwa ngokwesikhatsi sabaphindaphinda ukufika emva kwezinto ezintsha ukuze uzisebenzise kakhulu. Bahlola izinkinga nezindlela ezintsha ukuze ziyenza iingxenye nokulula okunqumekeleka kunye nokukhangelwa. Izilungiselelo eziyi-Research zixoxwa ngokuba ziza kulandela izindlela zezindawo zomsebenzi wamathathu, wemibuzo nokulima ukuba ziziphiwe izinkozo ezisafunda kunye neziyiqhaza. Ngokushesha, uma iphethenti yokuqala yesi-polymeric isocyanate yiya ngaphezulu kakhulu kumanye amathi wesifundo sesisobodiso, lokhu liya kuhluke ukuba zintlanti azinikezelwe ngokuphucwayo kunye nokuba zizivumelekile kakhulu ngalinye lililo lavela.
