I-Mofan Polyurethanes Co., Ltd., umvelisi ophambili kwikhemistri ye-polyurethane ephucukileyo, ibhengeze ngokusesikweni ukuveliswa ngobuninzi kwesizukulwana sayo esilandelayo.IiNovolac Polyols. Yenzelwe ubunjineli obuchanekileyo kunye nokuqonda okunzulu kweemfuno zezicelo zoshishino, ezi polyols ziphambili zimiselwe ukuchaza kwakhona imigangatho yokusebenza yeefoam ze-polyurethane eziqinileyo kumashishini amaninzi.

Iifoam ze-polyurethane eziqinileyo zizinto ezibalulekileyo kwi-insulation, ulwakhiwo, i-friji, uthutho, kunye nemveliso ekhethekileyo. Zixatyiswa ngenxa ye-insulation yazo yobushushu egqwesileyo, amandla oomatshini, kunye nokuqina. Nangona kunjalo, njengoko iimfuno zemarike zitshintsha—ziqhutywa yimigaqo engqongqo yokusebenza kakuhle kwamandla, imigangatho yokhuseleko ephezulu, kunye nesidingo sezisombululo ezinobuhlobo nokusingqongileyo—abavelisi bafuna izinto eziluhlaza ezingapheleli nje ekuhlangabezaneni nezi mfuno kodwa ezidlula ezi mfuno.

IiNovolac Polyols zikaMofan zimele inkqubela phambili kubuchwepheshe be-polyurethane.i-viscosity ephantsi, ixabiso le-hydroxyl (OH) elilungiselelwe kakuhle, ulwakhiwo lweseli olucothayo kakhulu, kunye nokungavuthi komlilo okungaphakathi, ezi polyols zivumela abavelisi befoam ukuba bafikelele kwimveliso esebenza kakuhle ngelixa bephucula ukusebenza kakuhle kokucubungula kunye nokusetyenziswa kwamandla.

1. Ubunzulu obuphantsi kunye nexabiso le-OH eliphuculweyo: Ukusebenza kakuhle kokucubungula kuhambelana nokuguquguquka koyilo

Enye yezona nzuzo zibalaseleyo zeMofan's Novolac Polyols kukubai-viscosity ephantsi kakhulu, ukususela kwi8,000–15,000 mPa·s kwi-25°COku kuncipha kwe-viscosity kuphucula kakhulu ukuphathwa ngexesha lokwenziwa kunye nemveliso, okuvumela ukuxubana okuthambileyo, ukucutshungulwa ngokukhawuleza, kunye noxinzelelo oluphantsi loomatshini kwizixhobo zemveliso. Kukwanceda ekuphuhliseniukusetyenziswa kwamandla okuncitshisiweyo, njengoko kufuneka ubushushu obuncinci kunye nokushukuma ukuze kufunyanwe umxube ofanayo.

Ukongeza,ixabiso le-hydroxyl (OHV)iiNovolac Polyols zikaMofan zinokubaeyenzelwe wena phakathi kwe-150–250 mg KOH/gLe parameter ehlengahlengiswayo inikezela abavelisi befoaminkululeko enkulu yokwenza, ngakumbi kwiuyilo oluthwala amanzi amaninzi, ezibalulekileyo kwizicelo ezithile zokufakelwa kwe-insulation kunye ne-structural foam. Ngokulawula ixabiso le-OH, ii-formulators zinokulungisa ngokuchanekileyo ubulukhuni be-foam, uxinano, kunye noxinano lwe-crosslink, ukuqinisekisa ukusebenza kakuhle kokusetyenziswa okujoliswe kuko.

2. Ulwakhiwo lweSeli oluFine kakhulu: Iipropati eziPhezulu zoBushushu nezobuGcisa

Ukusebenza kwefoam kuchaphazeleka kakhulu bulwakhiwo lwangaphakathi lweseli yayo. I-Novolac Polyols kaMofan inikaubungakanani beseli obuphakathi buyi-150–200 μm kuphela, nto leyo incinci kakhulu xa ithelekiswa ne300–500 μmidla ngokufumaneka kwiifoam ze-polyurethane eziqinileyo eziqhelekileyo.

Olu lwakhiwo olucolekileyo lubonelela ngeenzuzo ezininzi:

Ukufakwa kobushushu obuphuculweyo– Iiseli ezincinci nezifanayo zinciphisa ukudibana kobushushu, ngaloo ndlela ziphucula ukusebenza kobushushu befoam ngokubanzi.

Uzinzo oluphuculweyo lweMilinganiselo– Ulwakhiwo lweseli oluhle noluhambelanayo lunciphisa ukushwabana okanye ukwanda ngokuhamba kwexesha, okuqinisekisa ukuthembeka kwexesha elide.

Amandla Oomatshini Aphezulu– Iiseli ezincinci zinegalelo ekuqineni okuphezulu, into ebalulekileyo kwiiphaneli zokukhusela ezithwala umthwalo kunye nokusetyenziswa kwefoam yolwakhiwo.

Ngaphezu koko, iiMofan's Novolac Polyols zivelisa amagwebu aneumlinganiselo weeseli ezivaliweyo odlula i-95%Lo mxholo weeseli ezivaliweyo unciphisa ukungena komswakama okanye komoya, nto leyo ibalulekileyo ekugcineni ubushushu obuphantsi ngexesha lobomi bemveliso.

3. Ukuthintela ilangatye okuqhelekileyo: Ukhuseleko olwakhelwe ngaphakathi ngaphandle kokwenza izinto ngendlela engafanelekanga

Ukhuseleko lomlilo luyinto exhalabisayo rhoqo kwizinto zokukhusela ubushushu kunye nezinto zokwakha, ingakumbi njengoko imithetho yokwakha yehlabathi kunye nemigaqo yokhuseleko iya isiba ngqongqo ngakumbi. Isici seMofan's Novolac Polyolsukubambezeleka komlilo okuqhelekileyo—oko kuthetha ukuba ukumelana nelangatye yimpawu ebalulekileyo yesakhiwo seekhemikhali zento, kungekuphela nje ngenxa yezongezo.

Uvavanyo oluzimeleyo lwe-cone calorimeter lubonisa ukuba amagwebu e-polyurethane aqinileyo aveliswe nge-Mofan's Novolac Polyols afezekisaUkunciphisa kwe-35% kwizinga lokukhululwa kobushushu obuphezulu (pHRR)xa kuthelekiswa namagwebu aqinileyo aqhelekileyo. Le pHRR isezantsi iguqulela ekubeniukusasazeka kancinci komlilo, ukuveliswa komsi okunciphileyo, kunye nokhuseleko lomlilo oluphuculweyo, nto leyo eyenza ukuba ezi zinto zifaneleke kakhulu kwiindawo zokuhlala, zorhwebo, kunye nezoshishino.

Ukumelana nelangatye okuqhelekileyo kukwabonelela ngeenzuzo zokucubungula: abavelisi banokunciphisa okanye baphelise imfuneko yezongezo zangaphandle ezithintela ilangatye, benze lula ukwenziwa kwezinto kwaye banciphise iindleko zemveliso.
