Phenolol resin

Phenolol resin inonziwoBakelite, zvakare inozivikanwa seBakelite poda. Pakutanga isina ruvara (chena) kana yerovhi Kupokana neasina kusimba acid uye isina kusimba alkali, iyo ichaita kana iri nyaya yakasimba acid uye corrode kana yakasimba alkali. Nyura muacetone, mvura, doro uye mamwe organic sol. Inowanikwa nePolyconsons of phenolic aldehyde kana yayo inobva. Solid phenolic resin ndeye yero, inoonekera Icho chesin chakagadzirwa nePolycendonsation of phenol uye formaldehyde pasi pemamiriro ezvinhu, kusarerekera nekushambidza nemvura. Nekuda kwekusarudza kweChialsst, inogona kukamurwa kuva marudzi maviri: chirwere cheTremoplastic. Phenolikhi resin ine yakanaka acid kuramba, zvimiro zvekushambadzira uye zvinopisa zvinopesana, uye zvinoshandiswa zvakanyanya muAntiering, zvinoshatisa, murazvo unodzora vhiri kugadzira uye mamwe maindasitiri.

Phenololic resin poda ndeye mhando yeTermoplastic phenolic resin yakaumbwa nePolycononsation ye phenol uye formaldehyde mune acidic yepakati. Inogona kunyungudutswa mu ethanol uye iva arermossa nekuwedzera 6 - 15% urotropine. Inogona kuumbwa pa150°C uye ine imwe simba rekuita. uye magetsi ekusimbisa kwemisangano.

Chinhu chikuru chesipolic resin isimba kupisa kupisa, uye inogona kuchengetedza kutendeka kwayo kwekuvimbika uye kudzikisira kwakasimba uye kudzikisira kwakasimba kunyange pakupisa kwakanyanya. Naizvozvo, zveshuwa zveshuwa zvinoshandiswa muminda yakanyanya kupisa, senge zvinhu zvekuramba, zvinhu zvekupokana, zvinonamatira uye maindasitiri akawanikwa.

Iko kushandisirwa kwakakosha kwechiitiko chespenolic kwakafanana nekubhuka. Zvinyorwa zvesipiso zviri zviviri zvinopesana uye zvinoenderana nemhando dzakasiyana dze organic uye malorganic filers. Zvakakodzera zvakagadzirwa nenhengo dzinoyevedza dzakanyorova kunze nekukurumidza. Uye mushure mekuyambuka - Kubatanidza, kunogona kupa iyo inoshanda yemakina simba, kupisa kupisa uye zvivakwa zvemagetsi zvemagetsi zvekushandisa zvishandiso, zvekurezvera zvinhu zvinodzora, zvekupokana uye kubhowekana.

Mvura - Shoma renhema dzinogara kana doro.

Phenolic resin zvivakwa:

Kukwikwidza kwakanyanya: Chinhu chakanyanya kukosha chechiitiko chakatsikiswa kupisa, kunyangwe kupisa kwakanyanya, kunogona kuchengeta kutendeka kwayo kwakarongeka uye kugadzikana kwakazara.

Bond Simba: Iko kushandiswa kwakakosha kwechiitiko chespenolic sige singi. Zvinyorwa zvesipiso zviri zviviri zvinopesana uye zvinoenderana nemhando dzakasiyana dze organic uye malorganic filers.

Yakakwira kabhoni rasara reti: Under inert gasi mamiriro ne tembiricha yeanenge 1000°C, zveshuwa zveshuwa zvichabuditsa kabhoni yakakwira zvasara, izvo zvinokodzera kuchengetedza kugadzikana kwechigadziko.

Utsi hwakadzika uye hwakaderera utsi: zvichienzaniswa nedzimwe resin system, phenolic resin system ine zvakanakira utsi hwakadzika uye kuderera kwechinhu. Panyaya yechiitiko, iyo phenolol resin system yakagadzirwa neyesainzi fomon ichaderera zvishoma nezvishoma yekugadzira hydrogen, hydrocarbons, huku mvura uye kabhoni uye kabhoni oxides. Utsi hunoburitswa panguva yekuora kwechiochi idiki, uye utonge neutura hwakanyanya kuderera.

Kemical Resistance: Cross - Yakabatanidzwa Phenolic Resin inogona kuramba kuora kwezvinhu chero zvemakemikari zvinhu. Yakadai sepeturu, peturu, doro, glycol, mafuta uye akasiyana mahyritbons.

Kupisa kurapwa: Kupisa kurapwa kuchawedzera girazi tembiricha yekudziya kwemapepa ekurapwa, iyo inogona kuwedzera kuvandudza zvivakwa zveiyo resin.

Foamability. Kuenzaniswa nePolystyrene Foam, Polyvinyl Chloride Foam, Polyurethane Foam uye zvimwe zvinhu zvakatonga musika muchikamu chekutanga, ine chekuita kwakanaka kwazvo mumitemo yekudzoreredza.
