Ukwethulwa kwe-thermoplastic acrylic resin
I-Thermoplastic Acrylic Resins iyikilasi lama-thermoplastic resins enziwe nge-polymerizing acrylic acid, i-methacrylic acid kanye nokuphuma kwayo okufana nama-esters, ama-nitriles, nama-amide.Ingathanjiswa ngokuphindaphindiwe ngokushisa futhi iqiniswe ngokupholisa.Ngokuvamile, iyinhlanganisela ye-polymer eqondile, engase...Funda kabanzi -
Izici zezinto ezibonakalayo kanye nokusetshenziswa kwepulasitiki ye-propylene
I-Polymethyl methacrylate, ebizwa ngokuthi i-PMMA, eyaziwa ngokuthi i-plexiglass, eyaziwa nangokuthi i-acrylic.Inezici zokuqina, okunganqamuki, okusobala kakhulu, ukumelana nesimo sezulu, ukudaywa kalula nokwenza, futhi isiphenduke into esetshenziswa kakhulu epulasitiki esobala.I-Plexiglass iyindlela enhle kunazo zonke ...Funda kabanzi -
Umlando we-Plexiglass
Ngo-1927, usokhemisi wenkampani yaseJalimane washisisa i-acrylate phakathi kwamapuleti amabili engilazi, futhi i-acrylate yenziwa i-polymerized ukuze yakhe i-interlayer enjenge-viscous efana nenjoloba engasetshenziswa njengengilazi yokuphepha lapho kuphulwa.Lapho benza i-polymerized methyl methacrylate ngendlela efanayo, ipuleti le-plexiglass eline...Funda kabanzi -
Izici Zelensi Ye-Acrylic
A. Ukuminyana okuphansi: ngenxa yegebe eliphakathi kwamaketanga e-molecular, inani lama-molecule ngevolumu yeyunithi lincane, elinquma izinzuzo zelensi ye-resin: amandla adonsela phansi akhethekile kanye nokuthungwa okukhanyayo, okungu-1/3-1/2 we i-lens yengilazi;B. Inkomba ye-refractive emaphakathi: ukudla okujwayelekile kwe-CR-39 propylene...Funda kabanzi -
Isingeniso Selensi Ye-Acrylic
I-resin lens iyinto ephilayo.Ngaphakathi kuyisakhiwo seketango le-polymer, elixhunywe ukwakha isakhiwo senethiwekhi esinezinhlangothi ezintathu.Isakhiwo se-intermolecular sikhululekile uma kuqhathaniswa, futhi kunesikhala phakathi kwamaketanga amangqamuzana angakwazi ukukhiqiza ukugudluka okuhlobene.I-lig...Funda kabanzi
