Isicatshulwa esiqinisekisiyo sentsha sokugcina nge-2 izinto ezininzi ezifunekayo kwiimbali zokugqibela, phakathi kwezinye izinto ezisetyenziswa kwindawo yokugqibela yezinto eziyindawo ezikhoyo, futhi kumathathu nokuncedisi. Yi-MDI kunye nezi TDI Isocyanate niwe izinto ezithile ezinikezelayo. Ngoku baze bazange babonakele njengoko bafana, ukuphelwako kwezi zintlantolo ziyinto elungileyo yokubizo. Ukuba siya somntu, siya sebenzisa ukufunda kakhulu nge-MDI kunye nezi TDI Isocyanate, ukuze sibone lapho siyenza kwaye lapho siyusetshenziswa.
I-MDI kunye nezi TDI Isocyanate – Yintoni?
MDI (Methylene Diphenyl Diisocyanate) Ingxelo ekubanzi, kodwa yintlizyo yesiliso sokuqala sesifazamethi esingazama. TDI ifumanekayo kwi-Toluene Diisocyanate, ngokugcina. Ababini babenziwe ngokushesha kwi-isicatshulwa esemva kokwabo elichaza isixhumanisi. Izixhumanisi zesiya kumgangatho lokusebenzela ukufakwa komsebenzi wamandla okanye ukusetyenziswa kwezinto ezinamandla eziphakeme. Le mesebenzi wamandla uzisebenza ukuba amaxwebhu amanqwabe kunye nokuphakamisa nge-foam. Oku kwaye kukho ukuba imigqa emasiphepheni nokukhawulekiswa kwemibhalo ethile yomthimba. Kodwa MDI ayiqaphela ne-TDI. Ngokushesha abaningi ababili babenziwe ngokudifayeni futhi bavamile ngendlela yakho yokusetshenziswa kwezinto.
MDI kunye ne-TDI Isocyanate: Yintoni Indlela Yobunxele?
UMDI nokuthi UTDI zidifane kakhulu ngokwesibindi. Isibindi sikhankanyiso esisetyenziselwa ngeentsha yokugxileyo emva kokho. UMDI usibindi esijongiyo kunye nokuba, ukusetyenziswa kwakhiwo kwaye akukho umphumelelo okanye. Lento lenziwe kulapho uqale ukubona ubudala obunene okusetshenziswa. Zidifana ngamabini amaninzi: ukuba bantoni khona ngokusebenzela umthetho wokuhlola. UMADI ungenisa ngokuhluke kakhulu ngokusebenza ngokumoya kunye nokuthi UTDI ungene ngokuphinda ukufinyelela ngokusebenza ngokumoya. Iziproducte ezilungile ukuba zisebenze ngendaweni engaphandle kwezantsi, njengemfuyo apho izinkathelo zakhe zizozibuyela, zizobuya ngokulula kwi-MDI.
Yintoni Okungayisebenzi, MDI noma TDI?
UMDI noma TDI: Yintoni? Ngonye yezinto ezidinga imigomo ephakathi kwezintathu ezininzi lokusebenza noma lokusetshenziswa, usebenzisa i-MDI ngoba ayenza into yokubhedlalwa ngokumoya omncane. Kodwa, lo ntolo elandelayo kwi-product ezidinga amandla amaculi nokuba amaxhobo amahle angasetshenziswa, njengomgqabi wewoto; lokelokhu lizange lityenziswa nge-TDI elingana namandla amaculi kwaye lingena umthombo omuhle.
MDI vs TDI Isocyanate — Okungaphandle kwaye Okunempumelelo
MDI kunye neTDI zingene ngezinto ezithile kunye neziqalekeleyo. Izixhobo zakhe zihluke ngokushesha kunye nokuhambisana neentsha, ukuze ufumane ukusetyenziswa kwiindlela ezininzi lwezinhlobo zomoya. Ukuphazamiseka kwakungapheli ukufundiswa, kodwa akuzobonisa indawo elincinci lokubhala njengokoTDI. Ukuba wenza imibono engaphezulu, ingena emizini esikhombisa ukubhala okungcono. Lento yokuhlala yokuqala kunye nokuthiyo lwakukho ukubhalela ngokulandelana noMDI, ukuze liyinqaba lokuvuna lokusebenza lento.
Amagida Amasemthethweni Apha eMDI kunye neTDI Isocyanate
UMDI nokuba TDI ungenzi ukuphakamiswa nazo zonke izixhobo ezisetyenzisiweyo. Zingaphambili ukubenza kwiqinisekiso lapho zibekelwe ngaphandle kokuthi ziqukethe umzimba wakho okanye uma zihlobene nomphako wakho. Ngokwesiphi, i-gear yokususa kufuneka kuzosetshenziswa ngokuphambili lokhu olungena nge-chemicals lezi. I-protective gears, njengeglove nokumask, "zifuneka zisetshenziswa zodwa zikhona." Isiqephu esincinci sokuqala sifuneka usenze ngokulandelayo. Ukuthi inguqule ngokulandelayo isinkambo sempumelelo yokuba kukhonjwa ngemoya omusha ukuze angayiqhutywa amacalane amaholo. Uma uthi usebenzisa i-chemicals lezi kwenyumbeni - ngokushesha ukusebenza isenzo sendawo yesobizo - kufuneka udale intsimbi kakhulu kunye nokuseta zonke i-safety instructions ezidinga.
MDI kunye neTDI Isocyanate: Amagugu Ezi-Nye Uya Kufumana Ukusebenza ngeZibophezulu Ezine Engenayo Ukusetyenziswa kweZicala Zesi-Cheymi zezilungu ezinikezela iFoam Products ezithunyelwa Ngokugqibelekileyo. Zihlaba amandla okuningi olunqamene lokuhlola ukuba zikhona ngaphandle kokuthi zisebenzise imiswe esingabonakali. Bheka amanqaku amahlula kunye nokusetshenziswa kwesayivuri ngokubhekisisa kunye nokusetshenziswa kwezicala eziningi lapho uzisebenzisa izicala eziningi. MDI Isocyanate inikwaziwa eSANYING ukuze sihlola ukuba izicala ezityenziswa kwisebe lakethu siphumeleyo kunye nokuphathelleyo kakhulu. Ukukhulula ngezicala zakhiwo lapho ziyifundeka zithathelela lezo nto zethulela ukuba sihlalelanga ngenqanawe yethu kunye nokuhlola!
