Igama lemveliso:phenolic resin

Ifomathi yemolekyuli:

Inombolo yeCAS:9003-35-4

Imveliso yesakhiwo semolekyuli:

Iipropati zeMichiza:

I-Phenol-formaldehyde resin ilungiswa ngolu hlobo lulandelayo:
C6H5OH+H2C=O —> [-C6H2(OH)CH2-]n
IiResins zenqanaba elinye. Umlinganiselo we-formaldehyde kwi-phenol uphezulu ngokwaneleyo ukuvumela ukuba inkqubo ye-thermosetting yenzeke ngaphandle kokongezwa kweminye imithombo ye-cross-link.
IiResins ezinezigaba ezibini. Umlinganiselo we-formaldehyde kwi-phenol uphantsi ngokwaneleyo ukukhusela ukusabela kwe-thermosetting ukuba kwenzeke ngexesha lokwenziwa kwe-resin. Ngeli xesha i-resin ibizwa ngokuba yi-novolac resin. Emva koko, i-hexamethylenetetramine ifakwe kwizinto eziphathekayo ukuze isebenze njengomthombo weekhemikhali ze-cross-links ngexesha lomsebenzi wokubumba (kunye nokuguqulwa kwi-thermoset okanye imeko ephilisiwe).

Iintlobo ze-phenolic resins:

I-1, ii-Phenolic Resins ze-Friction Materials
2, iireyini zerabha yeTire
I-3, ii-phenolic resins ze-abrasives ezenziwe ngesamente
I-4, ii-Phenolic resins ze-bamboo kunye nezixhobo zokhuni
I-5, iiResins zePhenolic ze-Oilfield
6, ii-phenolic resins zokubumba iikhompawundi
7, ii-phenolic resins kwizinto ezifakwe ngaphakathi
8. Iireyini zeshishini lokugquma
I-9, ii-phenolic resins zezixhobo zokufakelwa kwe-thermal
I-10, ii-Phenolic resins ze-abrasives ezigqunyiweyo

Isicelo:

I-Phenolic resins isetyenziselwa iindawo ezinexabiso eliphantsi ezifuna iipropathi ezilungileyo zokugquma umbane, ukuxhathisa ubushushu, okanye ukuxhathisa imichiza. I-avareji yobomi beshelufu yale resin imalunga nenyanga e-1 kwi-21.1°C. Oku kunokwandiswa ngokuyigcina kwisikhenkcisi kwi-1.6 ukuya kwi-10°C. Ukutshintsha i-catalyst (ngokobukhulu be-cast) kunye nokunyusa ubushushu bokunyanga ukuya kwi-93 ° C kuya kutshintsha ixesha lokunyanga ukusuka kwi-8 h ukuya kwi-15 min.
Okunye ukucutheka kwenzeka ekubunjweni okugqityiweyo (0.012 ukuya ku-0.6 mm/mm), kuxhomekeke kubungakanani bokugcwalisa, isixa se-catalyst, kunye nenqanaba lokunyanga. Imijikelo yonyango ekhawulezayo ivelisa izinga eliphezulu lokucutheka. Kuba umjikelo wonyango unokukhawuleziswa, i-phenolics isetyenziswa kwimisebenzi emfutshane.
Amalungu e-phenolic asuswa ngokulula kubumba ukuba ii-arhente zokwahlukana ezicetyiswa ngumthengisi ziyasetyenziswa. I-Posteuring iphucula iipropathi ze-thebasic zokuphosa okugqityiweyo.
