Sena se etsa hore ho be le phokotso e tsotehang ea tšenyo ea bokaholimo nakong ea ho kopana ha abrasive, e qetellang e lebisa ho ntlafatso ea nako e telele ea sehlahisoa.
Keletso e sebetsang: Ho etsa bonnete ba ts'ebetso e nepahetseng, ke habohlokoa ho finyella ho hasana ho nepahetseng ka twin-screw extrusion, e thusang ho thibela karohano ea mekhahlelo le ho eketsa melemo ea li-additives.
Chengdu SILIKE Technology Co., Ltd ke morekisi ea ka sehloohong oa China oali-additives tsa silicone bakeng sa li-plastiki tse fetotsoeng. Khamphani e fana ka litharollo tse ncha tse etselitsoeng ho ntlafatsa ts'ebetso le ts'ebetso ea lisebelisoa tse fapaneng tsa polasetiki. E 'ngoe ea lihlahisoa tsa bona tse hlahelletseng keSILIKE Silicone Masterbatch LYSI-413,tlhahiso e sebetsang haholo ea pelletized e nang le 25% ea ultra-high molecular weight siloxane polymer e qhalakantsoeng ka polycarbonate (PC). Keketso ena e thehiloeng ho silicone e sebetsa haholo bakeng sa litsamaiso tsa resin tse tsamaellanang le PC. E ntlafatsa thepa ea ts'ebetso le boleng ba holim'a metsi ka ho ntlafatsa phallo ea resin, ho nolofatsa ho tlatsoa ha hlobo le ho lokolloa, ho fokotsa torque ea extruder, ho theola coefficient ea likhohlano, le ho fana ka khanyetso e phahameng ea mar le abrasion. Ntle le moo, masterbatch ena e thehiloeng ho siloxane e sebetsa joalo ka setlatsetso se khahlano le sekoaelo, se e etsa tharollo e ntle ea ho eketsa khanyetso ea lihlahisoa tsa PC mme qetellong e ntlafatse ts'ebetso ea tsona ka kakaretso le ho tšoarella.
2. UV-Cable Hard Coatings ka Nanotechnology
Kenya lilae tse thata tse thehiloeng ho siloxane kapa tsa hybrid organic-inorganic hard (mohlala, Momentive SilFORT AS4700 kapa PPG's DuraShield). Liaparo tsena li finyella boima ba pentšele ho fihlela ho 7H-9H, ho ntlafatsa haholo khanyetso ea pele.
Kenyelletsa liphahlo tse phekolehang ka UV tse nang le nanoparticles (mohlala, silika kapa zirconia) ho matlafatsa ts'ebetso ea ho hanyetsa ho khopa.
Molemo: E fana ka tšitiso e sirelletsang khahlano le mengoapo, lik'hemik'hale le ho senyeha ha UV, e loketseng lisebelisoa tsa optical le tsa likoloi.
Kopo: Sebelisa sekoaelo, sefafatsi, kapa sekoaelo sa phallo bakeng sa botenya bo lekanang (5-10 µm).
3. Matlafatso ea Nanocomposite
Kenya li-nanofillers tse kang nanosilica, alumina, kapa graphene oxide (0.5-2% ka boima ba 'mele) ho PC matrix. Tsena li eketsa boima ba holim'a metsi le ho ntlafatsa ho hanyetsa ho apara ntle le ho ama haholo pepeneneng haeba boholo ba likaroloana ke <40 nm.
Mohlala: Liphuputso li bontša 1% nanosilica ho PC e ka ntlafatsa Taber abrasion resistance ka 20-30%.
Keletso: Sebelisa li-compatibilizers (mohlala, li-silane coupling agents) ho netefatsa phallo e ts'oanang le ho qoba ho kopana.
4. Likopano tsa PC bakeng sa Ts'ebetso e Leka-lekaneng
Kopanya PC e nang le PMMA (10-20%) ho matlafatsa boima ba bokaholimo kapa ka PBT bakeng sa boima bo ntlafetseng le ho hanyetsa ho apara. Tsena li kopanya khanyetso ea "balance scratch" le matla a tšusumetso a tlhaho a PC.
Mohlala: Motsoako oa PC/PMMA le 15% PMMA o ka eketsa boima ba bokaholimo ha o ntse o boloka ho hlaka bakeng sa lits'ebetso tsa ponts'o.
Tlhokomeliso: Ntlafatsa likarohano tsa motsoako ho qoba ho senya botsitso ba mocheso kapa boima ba PC.
5. Mekhoa e tsoetseng pele ea ho Fetola Sebaka
Kalafo ea Plasma: Sebelisa plasma-enhanced chemical vapor deposition (PECVD) ho kenya liphahlo tse tšesaane, tse thata joalo ka silicon oxynitride (SiOxNy) holim'a PC. Sena se ntlafatsa khanyetso ea mengoapo le thepa ea ho apara.
Laser Texturing: Theha masela a manyane kapa a nano-scale holim'a PC ho fokotsa sebaka sa ho ikopanya le ho hasanya mengoallo, ho ntlafatsa ho tšoarella ha botle.
Molemo: Ho ngola mongolo ho ka fokotsa mengoapo e bonahalang ka ho fihla ho 40% lits'ebetsong tse fumanehang habonolo.
6. Metsoako e ekelitsoeng bakeng sa Synergy
Kopanya li-additives tsa silicone le lisebelisoa tse ling tse sebetsang joaloka PTFE (polytetrafluoroethylene) micropowders (0.5-1%) bakeng sa liphello tsa synergistic. PTFE e eketsa lubricity, ha silicone e ntlafatsa ho hanyetsa ho apara.
