I-MDI Isocyanate luhlobo oluthile lweekhemikhali ezisebenza ngenjongo ebalulekileyo ekwenzeni iimveliso ezahlukeneyo zemihla ngemihla. Iyinxalenye yeklasi yeekhemikhali ezaziwa ngokuba zii-isocyanates. Loo michiza iluncedo kakhulu ekuveliseni izinto ezahlukahlukeneyo, ezinjengogwebu olukwaziyo ukugquma izakhiwo zize zihlale zishushu, kunye nezaleko nezinto ezincamathelayo ezinokugcina izinto kunye. Ukuhamba ngaphandle kwe-MDI Isocyanate, izinto ezininzi esizisebenzisa rhoqo aziyi kuba namandla okanye zisebenze.
Yintoni i-MDI Isocyanate?
I-MDI, imfutshane yeMethyl Diphenyl Diisocyanate, yikhompawundi yemichiza edalwe kwizinto ezimbini eziyilayo. Le khemikhali lulwelo olucacileyo nolutyheli. I-MDI Isocyanate yenziwe ngokudibanisa ezinye iikhemikhali ezimbini. Ezo khemikhali ziyi-methylene diphenyl diisocyanate kunye ne-4,4-diphenylmethane diisocyanate. Ukusabela phakathi kwezi khemikhali zimbini kudala I-Isocyanate (MDI). Le nkqubo nayo ibalulekile njengoko ivumela ukuveliswa kweekhemikhali ezininzi.
Isetyenziswa Njani I-MDI Isocyanate?
Zenza ntoni iifektri okanye amashishini nge-MDI Isocyanate? Mhlawumbi ukusetyenziswa kwayo yonke indawo kukuveliswa kwe Polyurethane Foam Catalysts. Ligwebu elikhethekileyo elinemisebenzi emininzi ebonakalayo njengoko lisetyenziselwa ukugquma kwizakhiwo, ezimotweni, nakwifriji. I-Insulation inceda ukubamba ubushushu okanye ukubanda, kubalulekile kuzo zombini intuthuzelo kunye nokonga amandla. I-MDI Isocyanate isetyenziselwa ukwenziwa kogwebu, iingubo kunye nezinto zokuncamathelisa. Ezi mveliso zibaluleke kakhulu kuba zinegalelo ekuveliseni iimveliso ezomeleleyo ezinjengeemoto kunye nezixhobo zombane eziphila ixesha elide. I-MDI Isocyanate ikwabalulekile ekudalweni kwezinto zeplastiki, iipeyinti kunye nevanishi, ebonisa indlela enokuguquguquka ngayo le khemikhali.
I-MDI Isocyanate kunye nePolyurethane Foam
I-MDI Isocyanate isetyenziswa kakhulu ekwenzeni lyu ugwebu. Le foam ibonakala kwiimveliso ezininzi ebomini bethu, ukusuka kwiimoto ukuya kwiifriji ukuya kwizihlangu. Ithambile kwaye ngoko ke ikhululekile ekuchukumiseni, kodwa inamandla kakhulu kwaye ihlala ixesha elide, ngoko inokuthatha ukuxhatshazwa okukhulu. I-MDI Isocyanate idityaniswe nezinye iikhemikhali ukwenza i-polyurethane foam. Ezi ziquka ikhompawundi eyaziwa ngokuba yi-polyol kunye ne-agent evuthelayo. I-agent evuthelayo ibalulekile kuba yinto eyenza i-foam yande, inike ukukhanya kwayo kunye neempawu ezithambileyo. Nje ukuba i-foam ilungile, ifumana ukusetyenziswa kwayo kwi-insulation okanye i-padding kwiimveliso-izenza zikhululeke kwaye zigcinwe.
I-MDI Isocyanate kunye neeNqaku kunye neZincamatheliso
I-MDI Isocyanate ikwalicandelo elibaluleke kakhulu ekuveliseni iingubo kunye neembasa ezikhubekisayo. Zibalulekile ekwenzeni izinto ezinjengeemoto, nezixhobo zombane, kwaye izakhiwo zihlala ixesha elide, kwaye zisebenza ngcono. Ukwambathisa kwenziwa kumphezulu weemveliso ukwenzela ukukhusela imveliso kwimikrwelo, ukungcola, kunye neminye imoshakala. Oku kubenza bahlale bebukeka behle kwaye basebenze ngokufanelekileyo ekuhambeni kwexesha. Endaweni yoko, izinto zokuncamathelisa zisetyenziselwa ukuncamathelisa iikhora ezahlukeneyo zeemveliso kunye, nto leyo eyenza ukuba yonke into ibenzima kwaye yomelele ngakumbi. I-MDI Isocyanate ngokwayo idityaniswe nenye ikhemikhali, njenge-resin okanye i-hardener, ukudala iingubo kunye ne-adhesives. Ezi ndibaniselwano zisinika amandla okwenza iimveliso ezikumgangatho ophezulu ezingakhange zijongane nomthwalo wemihla ngemihla wabasebenzi.
