Kusiyana pakati pa polyurethane MDI ndi TDI machitidwe a elastomer makina

Chiyambi:

Makina a polyurethane elastomer amagwira ntchito yofunika kwambiri pamakampani amakono.Komabe, pankhani yosankha dongosolo la polyurethane, pali njira ziwiri zazikulu: dongosolo la MDI (diphenylmethane diisocyanate) ndi TDI (terephthalate).Nkhaniyi ifufuza kusiyana pakati pa machitidwe awiriwa kuti athandize owerenga kusankha bwino pa ntchito inayake.

I. Makina a Elastomer a Polyurethane MDI Systems

Tanthauzo ndi Mapangidwe: dongosolo la MDI ndi polyurethane elastomer yopangidwa kuchokera ku diphenylmethane diisocyanate monga zopangira zazikulu, zomwe nthawi zambiri zimakhala ndi zida zothandizira monga polyether polyol ndi polyester polyol.

Mbali ndi Ubwino:

Mphamvu yayikulu komanso kukana ma abrasion: Ma elastomer a MDI ali ndi mawonekedwe abwino kwambiri komanso amakhala okhazikika m'malo opsinjika kwambiri.

Kukana kukalamba kwabwino kwambiri: ma elastomer okhala ndi machitidwe a MDI ali ndi kukana kwa okosijeni ndi ma radiation a UV komanso moyo wautali wautumiki.

Kukana kwabwino kwa mafuta ndi zosungunulira: Ma elastomer a MDI amakhalabe okhazikika akakumana ndi mankhwala monga mafuta ndi zosungunulira.

Magawo ogwiritsira ntchito: Elastomers a MDI system amagwiritsidwa ntchito kwambiri popanga magalimoto, zida zamasewera ndi zinthu zamakampani.

II.Makina a elastomer a polyurethane TDI system

Tanthauzo ndi kapangidwe kake: TDI system ndi polyurethane elastomer yopangidwa ndi terephthalate monga zopangira zazikulu, nthawi zambiri zimakhala ndi zida zothandizira monga polyether polyol ndi polyester polyol.

Mbali ndi Ubwino:

Kutanuka kwabwino komanso kufewa: Ma elastomer a TDI ali ndi kutsika kwambiri komanso kufewa ndipo ndi oyenera pazinthu zomwe zimafunikira kumveka bwino kwa dzanja.

Kuchita bwino kwambiri kopendekera kotsika: Ma elastomer a TDI akadali ndi machitidwe abwino opindika m'malo otentha kwambiri, ndipo sizosavuta kupunduka kapena kusweka.

Oyenera mawonekedwe ovuta: TDI elastomers amapambana pakupanga mawonekedwe ovuta kuti akwaniritse zosowa zamapangidwe osiyanasiyana.

Mapulogalamu: Ma elastomer a TDI amagwiritsidwa ntchito kwambiri pamipando ndi matiresi, kupanga nsapato ndi zida zonyamula.

III.Kuyerekeza kwa machitidwe a MDI ndi TDI

M'munda wamakina a polyurethane elastomer, machitidwe a MDI ndi TDI ali ndi mawonekedwe ndi maubwino osiyanasiyana.Matebulo otsatirawa afananizanso kusiyana kwawo malinga ndi kapangidwe ka mankhwala, katundu wakuthupi, chitetezo ndi chitetezo cha chilengedwe, ndalama zopangira ndi malo ogwiritsira ntchito:

Monga tawonera pamwambapa, ma elastomers a polyurethane MDI system ali ndi mphamvu zambiri, kukana kukalamba komanso kukana mafuta, ndipo ndi oyenera kugwiritsidwa ntchito popanga magalimoto, zida zamasewera ndi zinthu zamakampani.Komano, polyurethane TDI system elastomers ndi elasticity wabwino, kusinthasintha ndi otsika kutentha mapindikira katundu, ndipo ndi oyenera kugwiritsidwa ntchito m'madera monga mipando ndi matiresi, kupanga nsapato ndi kulongedza zipangizo.

Ndizofunikanso kudziwa kuti dongosolo la MDI ndi lokwera mtengo kupanga, koma limapereka chitetezo chabwino komanso chitetezo.Mosiyana ndi izi, dongosolo la TDI limakhala ndi mtengo wotsika wopanga koma wokwera wa isocyanate ndipo ndi wochezeka pang'ono ndi chilengedwe kuposa dongosolo la MDI.Chifukwa chake, posankha makina a polyurethane, opanga ayenera kuganizira momwe zinthu zimagwirira ntchito, zofunikira zachilengedwe ndi zovuta za bajeti kuti apange pulogalamu yoyenera kwambiri yopangira kuti ikwaniritse zosowa zamitundu yosiyanasiyana.

IV.Zosankha Zogwiritsa Ntchito ndi Zopangira

Kusankha dongosolo loyenera la ntchito zosiyanasiyana: Poganizira zofunikira zamalonda ndi mawonekedwe a malo ogwiritsira ntchito, kusankha ma elastomers okhala ndi MDI kapena TDI machitidwe amaonetsetsa kuti ntchito yabwino ndi yotsika mtengo.

Kupanga zisankho zokhudzana ndi magwiridwe antchito ndi bajeti: posankha dongosolo, magwiridwe antchito, zofunikira zachilengedwe ndi zovuta za bajeti zimaganiziridwa kuti apange njira yabwino kwambiri yopangira.

Pomaliza:

Polyurethane MDI ndi TDI system elastomers aliyense ali ndi ubwino wake ndipo ndi oyenera mankhwala zosowa m'madera osiyanasiyana.Kumvetsetsa kusiyana kumeneku kudzathandiza opanga kupanga zosankha zodziwikiratu kuti awonetsetse kuti zinthu zawo zikuyenda bwino pamapulogalamu apadera.
