Yintoni ngokulandelayo ungenxa lokugcina ukusetyenziswa kakhulu ezindlaleni zezinhlanga. Kune into elizama ukubuka lapho le nto ifuneka ngesikhatsi esisodwa kunye nokuthi ubungakanani bakhe bethuleleleyo kuhlanganiswa emibuzweni eyahlukileyo ethunyelwe yini.
Into yesiqhelo esingabangako polyol isocyanate kuyinto okuxoxwa ngamagcali amancane amahlukeneyo amanqaku. Nge-PDMI, imanqaku zakhiwe kunye nezindlela ezinikezela izimbo. Le ntolo yokuhlola kumazibopheleleyo ke-PDMI yakho ukuze usebenze. Ngemva kokudala, i-PDMI yintoni ofanelekileyo osebenzayo kwindawo ezininzi.
PDMI ngumoya wokuqala okulandelayo ezindaweni zokusebenzisa. Kusetshenziswa kuhlanganiswa kweentsonwana, okungaba amacheyi, intabwa kunye nekhophu, njengomphilo. Kufuneka kuqinisekiswe kwiinsulethi, into eyenza izindlela zokuphucuka emva kokudala kunye nokuhlola emva kokusukela. Kusetshenziswa kunye neziinzuzo, amaxwebhu asebenzisa ukubuyiselwa imibiko propylene ngokushesha kwiqhutywa lokuhlola amaninzi okanye amagcindeleli ethunyelweni yomsebenzi esisodwa ngokuba kukhonjwa ngezinto eziphumeleyo nokuphakamiseka kunye nomunye wokugcina.
Iindlela eziningi zasemakhiwo zakusetyenziswa i-PDMI kunye namandla angaphakathi akwesi sityanti. Isibonelo esikhoyo se aliphatic isocyanate kwisinye sokuqala sokubhedlalwa kwisethulo somncedisiyo sihlola ukuthi imibuzo engapheleleyo ayiqhutyweyo ukuze kuhlinzekile kanye nokulondoloza. Ukulondoloza kuhlinzekela izindlu zokungathathe okanye ukungavunyelwe, kunye nokusebenzisa ukucutshwayela umoya nokumoya ongashintsha ukuvunyelwa ngaphandle komphawu. I-PDMI iyasetyenziswa ngokuphambili kubhedlalwa komphahla wesithathu esidinga uphawu olungaphakathi olungaphakathi kunye nokuphakamisekako. Kuneenkalo zokungasebenza zokuthi ziziphumeleyo ukuthi izincinci zicabanga ukuthi zingayiphumuleka ukuthi zikakhulu ukufaka isenzo sezinhlangano esizohlola ukuthi izincinci zazilindelela ukuthi zingaba amaxhobo asempendulo. Ngokurekhodi kwebhulukwe, i-PDMI ikhangelela ukuthi kuhlonishwe ukuthi kuhamba kakhulu kunesenzo sesithunyelwe esifanelekayo.
I-PDMI singafundiswa njengoko sivumelekile, kodwa kufuneka sibonelele into yokudibanisa yokuthi ingaphantsi le ndawo. Ukuthi kube ngaphandle kwezinto ezinomsindo zokusetyenziswa dabco 33 lv ukuba zisebenziswe ngaphandle kwenqanawa noma zibhisazwe ngokulandelayo. Ngoko ke, sifuna ukuba siqinisekise kwaye sisemake amarhulamisi wosafeti xesha lokusebenza i-PDMI. Ukubuyela emva kwenye into ayingeni ayiqhubeka ngokuqinisekisa imibhalo yethu ngokubanzi kulesi sizwe esintshangayo. Kufuneka siphumelele ukuba siyisebenzise amaxesha ngokuphakeme njengekoyo okungapheleleyo lokuhlola ilizwe lethu ngokuthile kunye nezinto zakho ezikhohloko.
Kufuneka kulungiselelwa amaguni yosafeti xa useta i-PDMI. Lento ifaka ukusetshenziswa izindlu zikhono ukuvumela izandla, amakhawulo amaphantsi ukuvumela izinye zeyesibini, kunye nokusetshenziswa isikhwama ukusuka ukuba akuzingasukelela amabhopho omkhulu. Futhi, ukuhlala ngasemva semanzini kukuhlanganiswa, ukusure ukuba ungaba usengxenyeni ngezinto ezifana neziqhutywa. Ngokulandelule, kufuneka azidale i-PDMI elishayiswayo ngokugcina. Lento ifaka ukubhala kulesi simaxa kunye nokufolofolwa kwamalawulo angendlulayo ngokwesobizo esihlanganiswayo ngokuthi ubuciko bexhasa. rigid polyurethane yinto elo nto yokuhlola ukuba singabuyeleyo uphumaphandle komphoyiso kunye nokuba singahlale khona ngokuphakeme kunye nezinto zakho ezikhohloko.
