Iposti yebhlog enomdla kakhulu malunga neekhemikhali ezi-2 ezibaluleke kakhulu ezifumaneka kwiimveliso ezahlukeneyo zemihla ngemihla kubandakanya ukugcwala kwamagwebu kumatrasi kunye nezihlalo zeemoto. I-MDI kunye ne-TDI Isocyanate yimichiza. Ngelixa zinokuvakala zifana, ukungafani kwabo omnye komnye kubaluleke kakhulu, eyona nto ibaluleke kakhulu ukuvuma. Masingene nzulu kwaye sifunde ngakumbi malunga ne-MDI kunye ne-TDI Isocyanate, ukuze siyazi ukuba isebenza njani kwaye apho isetyenziswa khona.
I-MDI kunye ne-TDI Isocyanate-Yintoni?
I-MDI (i-Methylene Diphenyl Diisocyanate) Oko kuvakala njengomlomo, kodwa ligama nje lentsapho yeekhemikhali. I-TDI ibhekisa kwi-Toluene Diisocyanate, ngokuchaseneyo. Bobabini ngamalungu entsapho ebizwa ngokuba yi-isocyanates. I-Isocyanates yintsapho ethile yeekhemikhali ezisetyenziswa kumlinganiselo omkhulu ukuvelisa iimveliso ezinogwebu. Ezi mveliso zithambile kwaye zikhululekile njengogwebu kwiibhedi zethu okanye i-padding kwizihlalo zethu zemoto. Kodwa i-MDI ayifani ne-TDI. Ngamnye unezakhiwo zakhe kwaye uziphatha ngendlela eyahlukileyo xa esetyenziswa kwiimveliso.
I-MDI kunye ne-TDI Isocyanate: Yintoni uMahluko?
I-MDI kunye ne-TDI zohluke kakhulu kwityhefu. Ubuthi buyingozi into ephathwayo nawe. I-MDI inetyhefu encinci kune-TDI, kwaye ke, ukusetyenziswa kwayo kunokukhuseleka. Leyo yingqwalasela ebalulekileyo ekukhetheni ukuba yeyiphi imichiza enokusetyenziswa. Ziyahluke ngenye indlela engundoqo: indlela abasabela ngayo kubushushu. I-MDI inozinzo olungcono kubushushu xa kuthelekiswa ne-TDI, i-TDI inamandla aphezulu okuguqula phezu kokufudumeza. Iimveliso ezinokuthi zibe kwindawo ezishushu, ezinje ngaphakathi ezimotweni apho amaqondo obushushu anokunyuka, ziyakuxhamla kolu uzinzo.
Yeyiphi omawuyisebenzise, iMDI okanye iTDI?
I-MDI okanye i-TDI: Yeyiphi? Kuyo nayiphi na imveliso enokufuna amaqondo obushushu aphezulu ngokusebenza kwayo okanye usetyenziso, sebenzisa i-MDI kuba ayinakubola kubushushu obuphantsi. Nangona kunjalo, into echaseneyo yimeko yeemveliso apho iimpawu ezithambileyo kunye ne-elastic zibaluleke kakhulu njenge-foam ye-mattresses; oku kungachazwa ngcono kusetyenziswa i-TDI enokunwebeka okukhulu kwaye iya kubangela imveliso yogwebu ethambileyo enobuhle obuhle.
I-MDI vs TDI Isocyanate — Okulungileyo nokubi
I-MDI kunye ne-TDI beza neseti yabo yezinto ezilungileyo nezingalunganga. Ayinatyhefu encinci kwaye inemida yokuphatha engcono malunga nobushushu, ngoko ungayisebenzisa kuluhlu olubanzi lweentlobo zemveliso. Icala eliphantsi lelokuba ngelixa kuthatha ixesha elide ukunyanga, ayizukwenza ibhondi yomelele njenge-TDI. Ithelekisa ne-TDI esebenza ngokukhawuleza kwaye yenza ibhondi eyomeleleyo. Oku kulungile kwiintlobo zeemveliso ezifuna ukuhlanganiswa ngokukhawuleza okukhulu. Nangona kunjalo, i-TDI inetyhefu ngakumbi kwaye ayixhathisi ubushushu njenge-MDI, ngoko ke kubalulekile ukuqwalasela ezi zinto xa ukhetha.
Izikhokelo zoKhuseleko ze-MDI kunye ne-TDI Isocyanate
I-MDI kunye ne-TDI zombini zinomngcipheko wokhuseleko onxulumene nazo. Zinokuba yingozi xa uphefumla okanye ukuba zidibana nolusu lwakho. Ke ngoko, izixhobo zokhuseleko zifuneka kakhulu xa usebenza nezi khemikhali. Iigiya zokukhusela, ezinjengeeglavu kunye nemaski, "kufuneka zihlale zisetyenziswa." Enye into ebalulekileyo kukusebenza kwindawo engenawo umoya. Oku kuthetha nje ukuba kufuneka kubekho umoya omtsha owaneleyo ukuze ungaphefumli imichiza eyityhefu. Ukuba usebenzisa ezi khemikhali ekhaya - mhlawumbi kwiprojekthi yokuzenzela - kubalulekile ukufunda ileyibhile ngononophelo kwaye unamathele kuyo yonke imiyalelo yokhuseleko oluza nayo.
I-MDI kunye ne-TDI Isocyanate: Izinto Ezine Okufuneka Uzazi Ukuze Uqalise NgeeMichiza ezimbini ezibalulekileyo ezisetyenziselwa ukuveliswa kweeMveliso zeFoam ozisebenzisayo imihla ngemihla. Zineempawu ezininzi ezenza ukuba zilungele izicelo ezikhethekileyo. Soloko uziqhelanisa nokhuseleko kwaye usebenzise izixhobo zokukhusela xa usebenzisa le michiza. I-MDI Isocyanate esetyenziswa kwi-SANYING ukuqinisekisa ukuba iikhemikhali ezisetyenziswa kwiimveliso zethu ze-foam zezona zikhuselekileyo kwaye zizinzile. Ukwazi ezi khemikhali kusinceda ukuba senze izigqibo ezingcono malunga nempilo yethu nokhuseleko!
