Ngaba iBhodi ye-Bakelite ingamelana nokuFikelela kwiMichiza?

Ii-resin ze-phenolic ezifana nebhodi ye-bakelite zaziwa kakhulu ngamandla azo kunye nokuguquguquka kwazo kwiindawo ezahlukeneyo zoshishino. Ukumelana kwayo nokuvezwa ziikhemikhali yenye yezinto eziphambili ezichaphazela ukusetyenziswa kwayo ngokubanzi. Le blogi ihlola ukumelana kweekhemikhali zebhodi ye-Bakelite kunye nendlela esebenza kakuhle ngayo kwiimeko ezivezwe ziikhemikhali. Siza kuhlola ukumelana kwebhodi ye-Bakelite nokuvezwa ziikhemikhali, ukusebenza kwayo kwiindawo zoshishino, kunye neenzuzo zayo ngaphezu kwezinye izinto.

Ibhodi ye-Bakelite ixhathisa njani ukuthotywa kwemichiza?

Ukuvaleka kwebhodi ye-bakelite yenye yezona zinto ziphambili ezenza ibhodi ye-bakelite ifaneleke kwiintlobo ngeentlobo zezicelo. Ngenxa yesakhiwo sayo seekhemikhali kunye neempawu zayo ezahlukeneyo, inokumelana nokuvezwa kweekhemikhali ngaphandle kokuwohloka.

I-formaldehyde kunye ne-phenol zidityaniswe nge-polymerization ukwenza i-synthetic structure bakelite, iplastiki ye-thermostable. Ukudibanisa okunqamlezayo kuvelisa inethiwekhi ye-phenolic sap ekhuseleke kakhulu kwaye ingaguquki kwiinkalo ezintathu. Esi sakhiwo sigcina ukuzinza kunye nokunyaniseka ngokuthintela ukungena kweekhemikhali ezininzi kwizinto eziphathekayo kunye nokusabela kwazo kunye nayo.

Ukutyeba okuNxibelelana ngako

Inqanaba le-cross-partner kwisakhiwo se-polymer ye-Bakelite igalelo ngokupheleleyo kwinkcaso yayo yezinto. Isixhobo esinobukhulu obunqamlezileyo obuphezulu bushiya indawo encinci yemixube eyenziweyo ukuba ingene kwaye inxibelelane nayo. engafane idumbe, ithambe, okanye inyibilike xa ibekwe kwizinyibilikisi nezinye iikhemikhali ngenxa yothungelwano oluxineneyo.

exhathisa ngokumangalisayo kuzo zombini iiasidi kunye neetyuwa, nangona ingumhlwa kunye nokuxhathisa okusisiseko. Le nkcaso ilindeleke kwizicelo kwizityalo zokuphatha i-compound, amaziko ophando, kunye neendawo ezahlukeneyo apho izinto ezitshabalalisayo zihlala zihlala khona. I-Bakelite ayiphenduli ngokukhawuleza kunye ne-acids ezininzi, umzekelo, i-sulfuric, i-hydrochloric, kunye ne-nitric acids, kunye neziseko zinokucinga nge-sodium hydroxide kunye ne-potassium hydroxide.

Performance in Relation to Organic Solvents Bakelite board's performance inokuchatshazelwa sisinyibilikisi esisetyenzisiweyo, nangona ukuxhathisa ngokubanzi kwizinyibilikisi ezininzi eziphilayo. Kuba isebenza ngokuchasene notywala, ioyile, kunye neehydrocarbons ezithile, inokusetyenziswa naphi na ngokukhuselekileyo. Nangona kunjalo, xa kuthelekiswa nezinye izinto, ukuvezwa kwizinyibilikisi ezinamandla njenge-acetone okanye i-toluene kunokubangela ukuthotywa okuthile.

Ukuxhomekeka kwendalo ukuxhathisa kwayo kwento kufikelela kukuqina kwayo kwendalo, ukuyivumela ukuba igcine iipropathi zayo nasemva kokuvezwa kwiikhompawundi eziqatha zokwenziwa ixesha elide. Ukusetyenziswa apho imathiriyeli ekulindeleke ukuba ibe sesichengeni kwiikhemikhali ixesha elide ngaphandle kokubeka esichengeni isidima sazo sesakhiwo okanye ukusebenza kwayo kufuna oku kuzinzo ekuhambeni kwexesha.

Lilonke, ukuxhathisa kwayo kwi-substance iphuculwa yindalo yayo eyomeleleyo, ubukhulu bokudibanisa okunqamlezayo, kunye nokuxhomekeka kwemvelo ngokuchasene ne-asidi, iityuwa, kunye nezinyibilikisi ezahlukeneyo zendalo. Yimathiriyeli eyomeleleyo yeemeko-bume zokwenziwa ezinobunzima ngenxa yezi mpawu.
