Izindawo zomthetho njengezini, ukubhuba, kunye nokuzoba izicarhu zisebenzisa amanzi ephakathi kwe-isocyanate. Iphakamiswa njengokugcino olunqanisiweni lwabantu lwendawo. Ngokuvamile, usebenzisa ngokwesikhatsi lokuhlola uphawu lwe-polyurethane. Ungabonelela lephawu kunesithuthi esingazange sinceda ngalinye ilizwe, njengoamathebhu akhothani, amathathu amahhovha kunye nokuphuma kwindawo yokulula amaxhobo. Ngekupheleni kwe-amanz ephakathi kwe-isocyanate, kuzobonakala ukuba kuhlanganiswe ukuthi uhlaleke umsebenzi wokuvela lezi zinto. Uphawu nje yasemva kwi-isibonelo sokuthi, amanzi ephakathi kwe-isocyanate zisebenza futhi ngokubheka ukungena amacoco kunye nokungena i-glue. Ukuthi okungenayo, ibonakala ukuba yileyo ichemisiteli enjalo elihluhleni kakhulu kwiindlela ezininzi, ngoko ke ayiqinisekise ukubuyela kumaxhobo kunye nokusebenzisa.
Kwaye manje sizokwenzela ngokuqondileyo ngemva kokuthi umlilo wamakhanati wenkabi lindile nesiwo esinye. Umlilo wamakhanati wenkabi lindile yindlela eyenza lokugcina amagruphi amabili amafuneki: igruphi lezamakhanati (-NCO) kunye nomgca wohholi (-OH). Lolu thuso oluzilandelayo kulula ukuba uhlalo lwamakhanati wenkabi lindile lispecial! Ukusuka ukuba umlilo wamakhanati wenkabi lindile liphumeleleyo nokulayishwa kwiqhutywa elingekayo i-hydrogen (amanzi, amalosholi, neti.), lapho lizama ukufumana umoya omncane. Umoya omncane owenza lokuncedisi laluleka umthombo ocula njengomsebenzi wasePolyurea.
I-Polyurea yintlango engelela, enhle, nesintsho esiqhelekileyo ngokuphambili lokuhlola; ukuhlola amaculi nokulula. Ngakho, yintlango elungileyo ezindaweni zikhaya apho uzodinga umphathisi wemfene kunye nezinye izinto, njengamavoti aze amaxwebhu okanye amakhaya. Ngaphezu kwesonto, i-Polyurea iyasetshenziswa ukuvimba amagwada ukufika kumazwe amastrong. Ukuba ufunda ukuthi iphi le nto i-Isocyanate water isenzo ngaphandle kokuthi i-Polyurea, uzoba ubani abahamba bafuna ukuthi baye babe amandla akukho.
Ngoba amaxhobo we-isocyanate amaninzi unokuhlela ngokubona, kufuneka uhlalelo lwakho lwezinto zikuhlaliselwe ngenqanawe. Ukuthi yiloo, ngoba akuyazi ukuba zizobuya ngezinto ezinye nokuba zizofuna ukuphumelela ukuba usetyenziswa ngokungcono. Kulesi sikhathi sonyaka lokusebenza ne-amaxhobo we-isocyanate, kufuneka izindlu zomphilo zihlaliswe ngokukhululeka. Yeyiphi iindlela, njengamanje aphantsi, ukuvimba umoya wewenzi, amagoggo lokuvimba imilondolozi yakho yokugcina umoya okanyezeleyo kunye nomasekwenta ukuvimba imilondolozi yakho yesithombe. Izindlu zakho zomphilo zingahlinzekela ngoku ungaphandle komoya omkhulu okanyezeleyo kunye nokusetyenziswa kwezinto ezifana namaxhobo we-isocyanate.
Bayayigqibela ukuba bahlalele emazibenini engamandla okwesiqhaza esethelayo. Yeyiphi iindlela, ukuba abangaphandle kwindawo elincinci, ngoba uvunyelwa phakathi komoya okanyezeleyo kunye nokuba imifowu ye-isocyanate angayityelela iphephandaba lakho. Ngokushesha kufuneka ubhaliswe ngendlela eyayiphumelela ukusetshenziswa kunye nokugcina kwe-amaxhobo we-isocyanate. Ukusetshenziswa kwemixhenxe ngokumile kunye nokusetshenziswa kwemibuzo evela ekhathaleni kuhlanganisa ukuxhasa kokuthi umuntu alandelise ingxelo.
Kwiindlela ezintsha, umthetho wamancamathanga we-I socyanate Mdi wenzelele uphawu olunyelekile. Izimphumelelo ezijongwe zidinga ukusetshenziswa kwe-socyanate amancamathanga ngomqondo osebenzayo phakathi komntu wesibayeni. Ngenkathi yindlela elisha yokubeka ngokulandelana nokuthi iisocyanate amancamathanga azikhethwe ngokupheleleyo. Amalendlela angazama ukusetyenziswa imibala engasebenzi ekugcinwa njengazo zonke izinto ezingasetyenziswa. Leli ntolwana lokuhlola kulandelayo kuhlanganisa ukusebenza kweminye imiphumela yokusebenza ngokuncane kunye nokungaba ngaphandle kokuhlola okanye kukhombisa indlu yesizathu.
Indlela esingene yokuqala yayenza yeyokusetshenziswa iinkomo zenkululeko neziqhaza kuhlanganiswa kwisebenzelo sokusetshenziswa socyanate amancamathanga. Ukuxhasa lokhu lindiselela ukufumanisa isenzo sesikhashana saso sonke lesi sefuthe lemfihlakalo wesintshontolo nokuhlola okanye ongasebenzi kuhlanganiswa nge-fosekhi. Ukusetshenziswa kwezinto ezifumanekayo kwindawo yokudibanisa zilindiselela ukufakelwa imithombo kunye nokuzipha ukuthi lo msebenzi uhlola ukuthi lwesizathu.
