I-Mofan Polyurethanes Co., Ltd., umsunguli ohamba phambili kwezekhemikhali ze-polyurethane ezithuthukisiwe, imemezele ngokusemthethweni ukukhiqizwa okukhulu kwesizukulwane sayo esilandelayo.I-Novolac Polyols. Yaklanywa ngobunjiniyela obunembile kanye nokuqonda okujulile kwezidingo zokusetshenziswa kwezimboni, lawa ma-polyol athuthukile ahlelwe ukuchaza kabusha amazinga okusebenza kwama-foam e-polyurethane aqinile ezimbonini eziningi.

Ama-polyurethane foam aqinile ayizinto ezibalulekile ekufakweni kokushisa, ekwakheni, ekuqandisweni, ekuthuthweni, nasekukhiqizweni okukhethekile. Ayaziswa ngenxa yokufakwa kwawo kokushisa okumangalisayo, amandla omshini, kanye nokuqina. Kodwa-ke, njengoba izidingo zemakethe zithuthuka—eziqhutshwa yimithetho eqinile yokusebenzisa kahle amandla, amazinga aphezulu okuphepha, kanye nesidingo sezixazululo ezinobungani nemvelo—abakhiqizi bafuna izinto zokusetshenziswa ezingagcini nje ngokuhlangabezana nalezi zidingo kodwa futhi ezidlula lezi zidingo.

I-Novolac Polyols kaMofan imelela intuthuko eqhubekayo kubuchwepheshe be-polyurethane.i-viscosity ephansi, inani le-hydroxyl (OH) elenziwe kahle, isakhiwo seseli esithambile kakhulu, kanye nokuncipha komlilo okungokwemvelo, la ma-polyol avumela abakhiqizi be-foam ukuthi bafinyelele ukusebenza komkhiqizo okuphezulu ngenkathi benza ngcono ukusebenza kahle kokucubungula kanye nokusetshenziswa kwamandla.

1. Ukuqina Okuphansi kanye Nenani Elilungiselelwe le-OH: Ukusebenza Kahle Kokucubungula Kuhlangabezana Nokuguquguquka Komklamo

Enye yezinzuzo ezivelele ze-Novolac Polyols kaMofan ukuthiukucasuka okuphansi ngokuphawulekayo, kusukela ku-8,000–15,000 mPa·s ku-25°CLokhu kuncishiswa kwe-viscosity kuthuthukisa kakhulu ukuphathwa ngesikhathi sokwakhiwa nokukhiqiza, okuvumela ukuxuba okubushelelezi, ukucubungula okusheshayo, kanye nokucindezeleka okuphansi kwemishini emishinini yokukhiqiza. Kuphinde kusize ekukhiqizeni.ukusetshenziswa kwamandla okuncishisiwe, njengoba kudingeka ukushisa okuncane kanye nokushukuma ukuze kufezwe ingxube efanayo.

Ngaphezu kwalokho, i-inani le-hydroxyl (OHV)ama-Novolac Polyol kaMofan angabaokulungiselelwe ngokwezifiso phakathi kuka-150–250 mg KOH/gLe pharamitha elungisekayo inikeza abakhiqizi be-foaminkululeko enkulu yokwakheka, ikakhulukaziimiklamo enamanzi amaningi, ezibalulekile ekufakweni kwe-insulation ethile kanye ne-structural foam. Ngokulawula inani le-OH, abenzi be-formula bangakwazi ukulungisa ngokunembile ubulukhuni be-foam, ubuningi, kanye nobuningi be-crosslink, ukuqinisekisa ukusebenza okuhle kakhulu kokusetshenziswa okuqondiwe.

2. Isakhiwo Seseli Esicwebezelayo: Izakhiwo Eziphakeme Zokushisa Nezomshini

Ukusebenza kwegwebu kuthonywa kakhulu yisakhiwo salo sangaphakathi samaseli. I-Novolac Polyols kaMofan inikezausayizi weseli omaphakathi ongu-150–200 μm kuphela, okuyinto enhle kakhulu uma iqhathaniswa ne300–500 μmngokuvamile kutholakala kuma-foam aqinile e-polyurethane ajwayelekile.

Lesi sakhiwo esihle kakhulu sinikeza izinzuzo eziningi:

Ukufakwa Kokushisa Okuthuthukisiwe– Amaseli amancane, afanayo anciphisa ukuhlangana kokushisa, ngaleyo ndlela athuthukise ukusebenza kokuvikela kwe-foam.

Ukuqina Okuthuthukisiwe Kobukhulu– Isakhiwo seseli esihle nesihlala njalo sinciphisa ukushwabana noma ukwanda ngokuhamba kwesikhathi, okuqinisekisa ukuthembeka kwesikhathi eside.

Amandla Aphezulu Okusebenza Kwemishini– Amaseli amancane anegalelo ekuqineni okuphezulu kokucindezela, okuyisici esibalulekile kumaphaneli okushisa athwala umthwalo kanye nokusetshenziswa kwe-foam yesakhiwo.

Ngaphezu kwalokho, i-Mofan's Novolac Polyols ikhiqiza amagwebu ane-isilinganiso samaseli avaliwe esingaphezu kuka-95%Lokhu okuqukethwe okuphezulu kwamaseli avaliwe kunciphisa ukungena komswakama noma komoya, okubalulekile ekugcineni ukuhanjiswa kokushisa okuphansi phakathi nesikhathi sokuphila komkhiqizo.

3. Ukumelana Nomlilo Okungokwemvelo: Ukuphepha Okwakhelwe Ngaphakathi Ngaphandle Kokuyekethisa Ukusebenza

Ukuphepha emlilweni kuyinto ekhathazayo njalo ezintweni zokuvikela ukushisa kanye nezinto zokwakha, ikakhulukazi njengoba imithetho yokwakha yomhlaba wonke kanye nemithethonqubo yokuphepha iba lukhuni kakhulu. Isici se-Mofan's Novolac Polyolsukuphelelwa amandla komlilo okungokwemvelo—okusho ukuthi ukumelana nomlilo kuyisici esiyisisekelo sesakhiwo samakhemikhali sezinto, hhayi nje umphumela wezithasiselo.

Ukuhlolwa kwe-calorimeter yekhoni okuzimele kubonisa ukuthi ama-foam e-polyurethane aqinile akhiqizwe nge-Mofan's Novolac Polyols afinyelela ku-Ukwehla okungu-35% kwesilinganiso sokukhishwa kokushisa okuphezulu (pHRR)uma kuqhathaniswa namagwebu aqinile avamile. Le pHRR ephansi ihumusha ibeukusabalala komlilo kancane, ukwehla kokukhiqizwa kwentuthu, kanye nokuphepha komlilo okuthuthukisiwe, okwenza izinto zifaneleke kakhulu ukusetshenziswa ezindaweni zokuhlala, zezentengiselwano kanye nezezimboni.

Ukumelana kwelangabi okungokwemvelo kunikeza nezinzuzo zokucubungula: abakhiqizi banganciphisa noma baqede isidingo sezithasiselo zangaphandle ezivimbela ilangabi, benze lula ukwakheka futhi banciphise izindleko zokukhiqiza.

Ukuqhuba Ukusungula Izinto Ezintsha Kuzo Zonke Izimboni

Ukwethulwa kwe-Novolac Polyols kaMofan kuvula amathuba amasha emikhakheni eminingi:

Ukwakha Nokwakha– Ukusebenza kahle kokuvikela kanye nokumelana nomlilo kuhlangabezana nezidingo zezindinganiso zesimanje zezakhiwo eziluhlaza.

Uchungechunge Olubandayo kanye Nesiqandisi– Isakhiwo esisezingeni eliphezulu samaseli avaliwe siqinisekisa ukufudumala okuhambisanayo ezindaweni zokuqandisa, izindawo zokugcina izinto ezibandayo, kanye nezokuthutha.

Izimoto kanye Nezokuthutha– Amagwebu aqinile kodwa alula asiza ekuthuthukiseni ukusebenza kahle kukaphethiloli ngenkathi ehlangabezana nezidingo zokuphepha.

Imishini Yezimboni– Amagwebu aqinile, asebenza kahle ekushiseni andisa isikhathi sokuphila kwemishini esebenza ezindaweni ezinzima.

Ngokuhlanganiswa kwayo kwezinzuzo zokusebenza, i-Novolac Polyols kaMofan ivumela abakhiqizi ukuthi bahlangabezane nezilinganiso zokusebenza eziqinile zanamuhla ngenkathi belungiselela imithetho yemboni yesikhathi esizayo.

Ukuzibophezela Ekusebenzeni Okuhle Okusimeme

Ngaphandle kokusebenza kobuchwepheshe, i-Mofan Polyurethanes izibophezele ekusimeni nasekuthwaleni umthwalo wemfanelo wemvelo. Ukuqina okuphansi kanye namanani e-OH afanele kusiza ukunciphisa ukusetshenziswa kwamandla ngesikhathi sokucubungula, kuyilapho ukusebenza kahle kokushisa kwama-foam aphumayo kunegalelo ekunciphiseni ukusetshenziswa kwamandla esikhathini sokuphila komkhiqizo. Ngaphezu kwalokho, ngokufaka izakhiwo ezivimbela umlilo ezingeni lama-molecule, i-Mofan isiza ukunciphisa ukusetshenziswa kwezithasiselo ze-halogenated, okuhambisana nemikhuba yomhlaba wonke yokwakheka kwamakhemikhali okuphephile, nobungani nemvelo.
