Mofan Polyurethanes Co., Ltd., ikigo gikomeye mu guhanga udushya mu bijyanye n'ubutabire bwa polyurethane bugezweho, cyatangaje ku mugaragaro umusaruro w'ikinyagihumbi gishya cyacyo.Novolac Polyols. Yakozwe hifashishijwe ubuhanga buhanitse kandi isobanukiwe neza ibyo ikoreshwa mu nganda, izi polyols zigezweho zigenewe kongera gusobanura amahame ngenderwaho y’imikorere ya polyurethane foams zikomeye mu nganda nyinshi.

Ifuro rya polyurethane rikomeye ni ibikoresho by'ingenzi mu bushyuhe, ubwubatsi, ubukonje, ubwikorezi, n'inganda zihariye. Bihabwa agaciro kubera ubushyuhe bwabyo budasanzwe, imbaraga za mekanike, no kuramba. Ariko, uko isoko rigenda rihinduka—biterwa n'amategeko akomeye yo gukoresha neza ingufu, amahame yo hejuru y'umutekano, no gukenera ibisubizo bitangiza ibidukikije—abakora barimo gushaka ibikoresho fatizo byujuje ibisabwa gusa ahubwo binarenze ibyo bisabwa.

Novolac Polyols ya Mofan igaragaza intambwe ishimishije mu ikoranabuhanga rya polyurethane.ubushyuhe buke, agaciro ka hydroxyl (OH) gakozwe neza, imiterere y'uturemangingo duto cyane, ndetse no kudakora neza kw'umuriro, izi polyols zituma abakora foam bagera ku musaruro mwiza mu gihe barushaho kunoza imikorere myiza no gukoresha ingufu.

1. Ubucucike buke n'agaciro ka OH gakozwe neza: Ingufu zo gutunganya zihuye n'uburyo bworoshye bwo gushushanya

Kimwe mu byiza bidasanzwe bya Mofan's Novolac Polyols ni ukoubushyuhe buke cyanekuva kuri8,000–15,000 mPa·s kuri 25°CUku kugabanuka k'ubushyuhe bw'ibinyabutabire birushaho kunoza uburyo bwo gukora mu gihe cyo gushushanya no gukora, bigatuma bivanga neza, bigatunganywa vuba, kandi bigagabanya imbaraga za mekanike ku bikoresho bikoreshwa mu gukora. Binagira uruhare mu gutuma ibikoresho bikoreshwa mu gukora birushaho kuba byiza.ikoreshwa ry'ingufu rigabanuka, kuko ubushyuhe n'ibyuka bike bikenewe kugira ngo habeho uruvange rumwe.

Byongeye kandi,Agaciro ka hydroxyl (OHV)bya Mofan's Novolac Polyols bishobora kubabyatoranijwe byihariye hagati ya 150–250 mg KOH/gIyi parametero ishobora guhindurwa itanga abakora ifuroubwisanzure bunini mu gutanga ibitekerezocyane cyane kuriigishushanyo mbonera cy'amazi menshi, ari ingenzi mu gukoresha ifuro rimwe na rimwe no mu buryo bw'imiterere yaryo. Mu kugenzura agaciro ka OH, abakora formulateur bashobora guhindura neza ubukana bw'ifuro, ubucucike, n'ubucucike bw'ifuro, bigatuma habaho imikorere myiza ku buryo bugenewe gukoreshwa.

2. Imiterere y'uturemangingo twinshi cyane: Imiterere myiza y'ubushyuhe n'imikorere ya mekanike

Imikorere y'ifuro iterwa cyane n'imiterere y'uturemangingo tw'imbere. Novolac Polyols ya Mofan itangaingano mpuzandengo y'uturemangingo ni μm 150–200 gusa, ibyo bikaba ari byiza cyane ugereranyije n'ibyo300–500 μmubusanzwe biboneka mu mavuta asanzwe akomeye ya polyurethane.

Iyi miterere myiza cyane itanga inyungu nyinshi:

Ubushyuhe Bukomeye bwo Gukingira Ubushyuhe– Uturemangingo duto kandi duhuye cyane tugabanya uburyo ubushyuhe buteranya, bityo bikanoza imikorere y’ubushyuhe muri rusange.

Iterambere ry'Uburyo bwo Guhagarara neza mu Bipimo- Imiterere y'uturemangingo twiza kandi duhoraho igabanya gucika cyangwa kwaguka uko igihe kigenda gihita, bigatuma tuba twizewe igihe kirekire.

Imbaraga z'ubukanishi zihebuje– Uturemangingo twiza tugira uruhare mu kugira imbaraga zo kwihuta cyane, ikintu cy'ingenzi mu gushyiramo ibikoresho bifasha mu gukurura no gukoresha ifuro mu buryo bw'imiterere.

Byongeye kandi, Mofan's Novolac Polyols ikora ifuro rifiteigipimo cy'uturemangingo twafunzwe kirenze 95%.Uyu mubare munini w’uturemangingo dufunze ugabanya kwinjira k’ubushuhe cyangwa umwuka, ibi bikaba ari ingenzi cyane mu gutuma ubushyuhe buguma muke mu gihe cyose ibicuruzwa bimara.

3. Kudashira kw'umuriro: Umutekano wubatswemo nta gutakaza imikorere

Umutekano w'inkongi ni ikibazo gikomeje kugaragara mu bijyanye no gushyira ibintu mu buryo butuje n'ibikoresho by'ubwubatsi, cyane cyane ko amategeko mpuzamahanga y'ubwubatsi n'amabwiriza agenga umutekano bigenda birushaho gukomera. Mofan's Novolac Polyols iragaragazagutinda k'umuriro bisanzwe—bivuze ko kurwanya umuriro ari ingenzi mu miterere y’ibinyabutabire by’ikintu, atari ingaruka z’inyongera gusa.

Ibizamini byigenga bya kalorimetero byerekana ko ifuro rya polyurethane rikomeye ryakozwe na Mofan's Novolac Polyols rigera kuKugabanuka kwa 35% mu gipimo cyo kurekura ubushyuhe bwinshi (pHRR)ugereranije n'ifuro risanzwe rikomeye. Iyi pHRR iri hasi isobanuragukwirakwira buhoro k'umuriro, kugabanya umwotsi uturuka mu kirere, no kunoza umutekano w'inkongi, bituma ibikoresho biberanye cyane no gukoreshwa mu mazu yo guturamo, ubucuruzi n'inganda.

Ubudahangarwa bw'umuriro busanzwe butanga kandi inyungu zo gutunganya: abakora bashobora kugabanya cyangwa gukuraho gukenera inyongeramusaruro zirinda umuriro zo hanze, byoroshya imvange y'ibicuruzwa ndetse bigashobora kugabanya ikiguzi cyo gukora.

Guteza imbere udushya mu nganda

Ishyirwaho rya Mofan's Novolac Polyols ritanga amahirwe mashya ku nzego nyinshi:

Inyubako n'Ubwubatsi– Ubushobozi bwo gukingira no kurwanya inkongi y'umuriro byujuje ibisabwa n'amahame agezweho y'inyubako zishaje.

Urusobe rw'ubukonje n'ubukonje- Imiterere myiza y’uturemangingo dufunze ituma habaho ubushyuhe buhoraho mu byuma bikonjesha, mu bubiko bukonjesha, no mu gutwara abantu.

Imodoka n'Ubwikorezi– Ifuro ryoroheje ariko rikomeye rifasha mu kunoza imikorere myiza ya lisansi mu gihe ryujuje ibisabwa mu by’umutekano.

Ibikoresho by'inganda– Ifuro riramba kandi rikoresha ubushyuhe bwinshi rituma ibikoresho bimara igihe kirekire mu bikorwa bikorerwa ahantu hagoye.

Bitewe n’inyungu zayo mu mikorere, Novolac Polyols ya Mofan ifasha abakora ibicuruzwa kugera ku bipimo ngenderwaho by’imikorere muri iki gihe mu gihe bitegura amabwiriza y’inganda z’ejo hazaza.

Ubwitange mu Indashyikirwa Irambye

Uretse imikorere ya tekiniki, Mofan Polyurethanes yiyemeje kubungabunga ibidukikije no kurengera ibidukikije. Ubukana buke n'agaciro ka OH gashingiye ku bipimo byayo bifasha kugabanya ikoreshwa ry'ingufu mu gihe cyo gutunganya, mu gihe ubushobozi bwo gushyushya ifuro rivamo butuma ikoreshwa ry'ingufu rigabanuka mu gihe cyose cy'ubuzima bw'ibicuruzwa. Byongeye kandi, binyuze mu gushyiramo imiterere irinda umuriro ku rwego rwa molekile, Mofan ifasha kugabanya ikoreshwa ry'inyongera za halogenated, ijyanye n'icyerekezo cy'isi yose ku bijyanye n'imiti itekanye kandi idafite ingaruka ku bidukikije.
