I-Isocyanates kunye ne-polyols ziimeko eziphambili ezisetyenziswa kwiindustri ezahlukeneyo ukwenza iintengiso ezininzi. Kufuneka kuhlulwe phakade phakade kule mibini ukuze kwenzeke into enobumbeko obungcono kunye nobomi, kwaye iintengiso ezimangalisayo. U-SANYING, umphathi omkhulu wokuqala, kunye nothimba lokusebenza kule ndawo yinto ekhoyo yinxalenye eqhamuka kakhulu, ngoko ke sizazi kahle le miqondo emva koko sibonise ngokuthi sithetha nje kwaye sicinge.

Imisebenzi ye-Isocyanates kunye ne-Polyols Ngokwahlulahlula Iindustri

I-Isocyanates zihlala ziyafumaneka kwiindustri ze-automotive, yokuqakatha kunye nokuvelisa izixhobo. Ziguqule kakhulu ekwenzeni i-polyurethane foams, iintshayelelo, i-adhesives kunye ne-sealants. I Isocyanate (MDI) zibophelela kwiziphumo ezimangalisayo, ubunzima, ukuzinceda kwaye nokulawula. Ngakolunxe, i-polyols zihlanganiswa ne-isocyanates ukuze zenze amanzi apha e-polyurethane. I-polyols zisetyenziswa ukulungisa ubuncinane okanye ubunzima kunye neengcinga ezinye zomthwalo wokusebenza. Mzabalazo unokufunyanwa kumzabalazo njengefoams enezizima, i-elastomers kunye ne-intshayelelo.

I-Isocyanates kunye ne-polyols zisetyenziswa kakuhle ekwenzeni uhlobo olunye lwemfanelo. Kwindustri ye-automotive, umzekelo, i-isocyanates zisetyenziswa ekwenzeni iintshayelelo ezingenamandla, ezingenaphutha ngexesha elipheleleyo kwiindawo zangaphandle zezimoto. I-polyols zibaluleke kakhulu ekunika ubomi bonke kunye nomthelela wezihlahla zefomy eziyinxalenye zezimoto. Kukusasa, polyol kunye no-isocyanate unceda ekugcineni izinto zokusebenza kakhulu, ngelixa i-polyols zisetyenziswa ukudibanisa iingcindezi ukuze zenze amandla kunye namandla okukhawuleza. Ubunzima phakathi kuka-isocyanates kunye ne-polyols kwiziganeko ezahlukeneyo kukuba kuyakwazi njani ii-materials zifuna ngaphakathi komsebenzi ukuze kufunyenwe iindlela eziphumelelayo zokwenza umkhiqizo ongcono konke.

Iindlela Ezifunekayo Zokusetshenziswa Kwi-Isocyanates kunye Ne-Polyols Ekwenzeni

Nangona i-isocyanates kunye ne-polyols inemiphakanyiso ekwenzeni, zinezixhobo ezininzi ezihlala zibonakala "imali-efundiyo" ezingazange ibe yinxalenye yesimo esinjalo. Enye yezinkinga ezibalulekileyo nge-isocyanates yiimpawu zempilo. Ukuthwalwa kwi-isocyanates kungathetha iinkxalabo zomoya, ukuchitha kwisondo kunye neengcinga ezinye zempilo. Ukuphatha iziphumo zesisicwangciso kudinga iindlela zokuphepha eziphathekayo kuxhomekeke kumthetho wokuphepha kunye nokuvavanywa.

Ngokohlanya, i-polyols ingaba yindlela ebalulekileyo ngamandla nokuphathwa kwayo. Ukusebenzisa uhlobo olungavumelekanga lwepolyol okanye ukuxhunya i-polymer polyols engavumelekanga kungenza ubunzima bomsebenzi wemveliso kunye nokuphelelwa kwisefile. Kufuneka nje amabhengele bakhuseleke ekukhetheni i-polyol echanekileyo yesilinganiso, kwaye bakwenze umxholo ocacileyo nokuphatha kwisebenzi ukuze akhubazi imiba yokhangalalo.

ukubona ukwahlukana phakathi kwe-isocyanates ne-polyols, nokufundisa ngamaxabiso amabelana ngumthombo wengcinga yeziganeko zokusebenza, kukho kwiindlela ezizimeleyo zokuphatha iziganeko. Umdlalo ophakade kaSANYING ngale ngxaki ungasebenzisa amabhangela ukuthintela le ngxaki kwaye kuqinisekise ukuba kwenzeke ngokushesha imveliso enobumba.

Kutheni I-Isocyanates Ayiyo I-Polyol—Imbazosothengiso

Kwimarike ye-wholesale, ii-isocyanates kunye nee-polyols zizinto ezimbini ezibalulekileyo ezisetyenziswayo jikelele. Ii-isocyanates zizinto ezinegroup esebenzayo R−N=C=O kwaye ii-polyols zinamaqela amaninzi e-hydroxy. Olunye umahluko phakathi kwee-isocyanate nee-polyols sisakhiwo seekhemikhali. Ii-isocyanates ziinxalenye ezisebenza ngokutsha ezinokudityaniswa neepolyols ukuvelisa i-polyurethane, imveliso eninzi esetyenziswa ngokubanzi kumashishini amaninzi. Ngokwahlukileyo, iipolyols zixabiswa njengokunika ubhetyebhetye kunye neempawu zokubuyela kwimveliso ye-polyurethane.

Fumana Iingenelo Zee-Isocyantes Neepolyols Kwiimfuno Zokuthengisa Ngokubanzi

I-Isocyanates neepolyols zinamathandabuzo amaninzi kumsebenzi wokuthengisa. I-Isocyanates ezobala ngokukhawuleza zaziwa ngokubala ngokukhawuleza kwazo, okuquka kakhulu kumsebenziso owanelekileyo othula kakhulu. Zihlale kakhulu kwi substrates ezahlukeneyo kwaye zingafumaneka njengeempahla yokufaka, iindleko kwaye iiseyilenti. Ngokutshona, iepolyols zifundiswa ngokwenza ubunzima kwaye ukuba yinxibelelaniso yezinto ezenziwe ngepolyurethane. Zinezimali ezilungileyo kunye nokukhululwa kwegcine, ngoko ke zilungile apho izinto ezinezilingo ezithile zidinga.

I-Isocyanates Nge-Polyols: Okufunwano Kuyo xa Uthenga Ngokujikeleze

Xa uyenzela isiko sengcimbi, kubaluleke kakhulu ukwazi uguquleko phakathi kwezocyanates nezipolyols ukuze ukhethe iindlela ezichanekileyo yesiseko sakho. I-Isocyanates zinxulumene ngokuphakade ngaphandle kwezipolyols ngokuba ziyaneleyo kwaye zisenziwa ziye zendaweni ephucukileyo. Zinika iimpawu eziphambili kwaye zihlathile kwiindlela ezininzi zengcimbi. Ngokulingana, i-polyols zinzima, zibonisa ubume obugqithisayo beempawu kwiindlela ezininzi zokusebenza. Abathengisi abacayishwa bangakholisa phakathi kwezocyanates nezipolyols ngokwaziyo uguquleko kumsebenzi njengekuthetha ngenani.

I-Isocyanates neepolyols zisebenza njengeziko kumthengi wesishipha, zinikeza iinkcukacha ezithile, ezenzelekileyo kwiindlela ezahlukeneyo. Xa abathiya ngokuphakade nabathengi abakhulu baziyo iimeko ephambili phakathi kwezi zinto ezibini, bangayidlula isigqibo esihle kangaka ngokuba yintoni efunekayo kuzo zonke iindlela zabo. U-SANYING unika i-aliphatic strong ne-aromatic isocyanates kunye neepolyols ukuze akwazi ukuthembela iimfuno ezininzi zokusebenzisa kumthengi wesishipha.
