Igama lomkhiqizo:phenolic resin

Ifomethi Molecular:

Cas Cha:9003-35-4

Isakhiwo samangqamuzana somkhiqizo:

Izakhiwo Zamakhemikhali:

I-phenol-formaldehyde resin ilungiselelwe kanjena:
C6h5OH + H2C = O -> [-c6hh2 (oh) CH2-] n
Ama-resins esiteji esisodwa. Isilinganiso se-Formaldehyde esiya ePhenol siphakeme ngokwanele ukuvumela inqubo ye-thermosettong ukuthi yenzeke ngaphandle kokufakwa kweminye imithombo yezixhumanisi.
Ama-resins aneziteji ezimbili. Isilinganiso se-Formaldehyde kuya ku-Phenol siphansi ngokwanele ukuvikela ukusabela kwe-thermosettet kusuka ekuveleni ngesikhathi se-resin. Ngalesi sikhathi i-resin ibizwa nge-novolac resin. Kamuva, i-hexamethyletetetramine ifakwa ezintweni ezizosebenza njengomthombo wezixhumanisi zamakhemikhali ngesikhathi sokusebenza kokubumba (kanye nokuguqulwa ku-thermoset noma i-termoset noma ekwelapheni isimo).

Izinhlobo ze-phenolic resins:

1, Phenolic resins ngezinto zokwenziwa kwezingxabano
2, Tire Rubber resins
3, Phenolic resins for abrasives anenkohliso
4, Phenolic resins for bamboo kanye nezinto zokhuni
5, Phenolic resins for uilfield
6, Phenolic resins for compounds yokubumba
7, Phenolic resins ngezinto ezifakiwe
8, ama-resins embonini ye-coating
9, Phenolic resins ngezinto zokwehlukanisa okushisayo
10, Phenolic resins for abrasives ehlanganisiwe

Isicelo:

Ama-Phenolic Resen asetshenziselwa izindleko ezingekho engxenyeni ephansi yokufakelwa kwezindawo ezinhle, ukumelana nokushisa, noma ukumelana kwamakhemikhali. Impilo yeshelufu yeTheavivage yale Resin imayelana nokubopha oku-1 21.1 ° C. Lokhu kunganwetshwa ngokugcina i-Ina esiqandisini ngo-1.6 kuye ku-10 ° C. Ukushintshanisa i-catalyst (ngokuya ngobukhulu be-cast) Ukuqongelela izinga lokushisa lokwelashwa kuya ku-93 ° C kuzoshintsha isikhathi sokwelapha kusuka ku-8 h kuze kube yimini ka-AS15 imizuzu.
Ezinye ze-shrinkage zenzeka ekushisweni okuqediwe (0.012 kuya ku-0.6 mm / mm), ngokuya ngokuhlukahluka kwe-filler, inani le-catalyst, kanye nokwelashwa okuthe xaxa. Imijikelezo yokulapha ngokushesha ikhiqiza i-shrinkage ye-shrinkage. Njengoba umjikelezo welapha ungaba ne-beaclereted, ama-phenolics asetshenziswa ekusebenzeni okuminyaniswa okufushane.
Izingxenye ze-Phenolicolicolic zisuswa kalula ku-incwajana uma ama-ejenti ahlukaniswayo anconywe umphakeli. I-Postteight ithuthukisa izakhiwo ze-thebasic zokuphonsa okuqediwe.
