Isisele lwe-PTSI isocyanate eliphakamisiwe ngamagcindeleli anganye, ngokubanzi polyols, iyayiphiwa ngokushesha. Le ntshona yokuphawula iphawule ifana neentsha ezimbili ezinikezelwe njengamasisekelo esingaphambili. Ukugcwalisa olwandle lwakuxhasa ukuba ikhethwe umthombo omkhulu. Lento lokugcwaliswa liyaziwa polymerization , lokhu libonisa ukuthi i-polyurethane ingakho ngenxa yokungcono, kwaye engakho ukudluliselwa kakhulu. Lonto lingalinde ukuthi izinto ezinikezeliweyo nge-polyurethane zazifuneka zihlobene nezinye izinto ezinomsindo, lokhu kuhle ngokuthi kunesixhobo saso!
Uya kubona ukuba uzoba ukusuka ngokulungileyo ipoliyuthane kwiinyaniso ezinikela zonke izinto esiyenza kulesi sikhathi sesihlanu. Iyenzeka kumathathu zethemba ukuba zibuyele ngaphakathi, kusici ukuba zisize kube ngenxa, kwezintsha ukuba zisize ukukhuseleka kunye nokuhlola kakhulu. Ngoku PTSI isocyanate, lezi zinto ziqhelekile kanye nokuba zisize ukwenza okungasebenzi sonke esisebenzayo.
Xesha lomkhulu ngokusebenzisa PTSI isocyanate, umoya wemoya ubizwa namandla. Ngexesha elandelayo, waziwe ukuthi kufuneka usebenze ngixhobo elingezantsi lokhu omoya wendawo angavumele. Imininingwane ezikhankanyiswayo njenge PTSI isocyanate kufuneka zibhalwe ngokubona ngeamandla ezifanekiso ezincedayo nokugcina. Lento litshabalalela ukuthi ufanele uye ube usapho lwendawo oluhlanganiswa. chloro sulfonyl isocyanate
Bengakho abantu ababangela baphindvula amaxwebhu okushona amanye amagama lwe PTSI isocyanate aqhamuka kakhulu, yeyiphi inxalenye ixhasa kunokuba ayisebenza ngokukhupheleleyo kunye nokusetshenziswa komoya engaphezulu. Baphindvula kwiinkcukacha ezintsha ezincedayo ekutheni luhlaza kwenze izinto zabo zikululekileyo kwindawo yokuhlala. Ukusuka nokungena iindlela ezinhloko zokuhlala ngokumthethisiweyo, sizoba sithola ngokulandelana nokubuyiselwa kweentloko, yeyiphi ukuthi siyakwazi ukwenza polyurethane ngokulandelana nokuhlala ngokumthethisiweyo. Lento libizwa namandla ngokuba wonke umntu ungamnje ukuthi afuna ukusindezelwa kwesonto esiqhelekanga.
Izinyathelo ezininzi zezisele PTSI isocyanate zikhulula ngamabini amandla, kwiindawo eziningi ezinokuthiweyo, ukusukela kumahlalelo okanye umsebenzi wemitha. Kumahlalelo, yikutsi yiyaqashwa ukuba iindlebe. Amasiko ame aqinisekisa ngoba abantu bakhuseleka ukuhlobene nokuhlola imibuzo emangweni ezintathu ezintathu ngezinyanga ezincinci ezisemva kwezinsimbi ezizicacileyo nokuhlola imigomo eziphumayo ezisemva kwezinsimbi ezizicacileyo. Lento lokuhlinza inani lemfenyo kunqumelela abantu bakufuneka babuyele kuwo wonke.
