Mokhoa oa ho sebetsana le squeaking lits'ebetsong tsa kahare tsa koloi,
SILIKE Anti-squeaking masterbatch SILIPLAS 2070, Tsela ea ho sebetsana le ho squeaking ka hare ho koloi,
Phokotso ea lerata ke taba e potlakileng indastering ea likoloi. Lerata, ho thothomela le ho thothomela ha molumo (NVH) ka hare ho cockpit e hlahella haholo likoloing tsa motlakase tse khutsitseng haholo. Re tšepa hore ntlo e tla fetoha paradeise bakeng sa boikhathollo le boithabiso. Likoloi tse ikemetseng li hloka sebaka se khutsitseng sa kahare.
Likarolo tse ngata tse sebelisoang ho li-dashboards tsa likoloi, li-centre consoles le li-trim strips li entsoe ka polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) alloy. Ha likarolo tse peli li tsamaea ka mokhoa o batlang o lekana (stick-slip effect), khohlano le thothomelo li tla etsa hore lisebelisoa tsena li hlahise lerata. Litharollo tsa setso tsa lerata li kenyelletsa ts'ebeliso ea bobeli ea litlolo, pente kapa mafura, le li-resin tse khethehileng tse fokotsang lerata. Khetho ea pele ke mekhoa e mengata, ts'ebetso e tlaase le ho se tsitse ha lerata, ha khetho ea bobeli e theko e boima haholo.
Silike's anti-squaking masterbatch ke polysiloxane e khethehileng e fanang ka ts'ebetso e ntle ea ka ho sa feleng ea ho thibela ho kokota bakeng sa likarolo tsa PC / ABS ka theko e tlaase. Kaha li-anti-squeaking particles li kenngoa nakong ea ho kopanya kapa ho etsoa ka ente, ha ho hlokahale mehato ea morao-rao e fokotsang lebelo la tlhahiso. Ho bohlokoa hore SILIPLAS 2070 masterbatch e boloke thepa ea mochini ea PC / ABS alloy-ho kenyeletsoa le ho hanyetsa ha eona ho tloaelehileng. Ka ho holisa tokoloho ea moralo, theknoloji ena e ncha e ka thusa li-OEM tsa likoloi le maemo ohle a bophelo. Nakong e fetileng, ka lebaka la ts'ebetso ea morao-rao, moralo o rarahaneng oa likarolo o ile oa e-ba thata kapa o sa khonehe ho finyella tšireletso e feletseng ka mor'a ts'ebetso. Ka lehlakoreng le leng, li-additives tsa silicone ha li hloke ho fetola moralo ho ntlafatsa ts'ebetso ea tsona e khahlanong le ho squeaking. Silike's SILIPLAS 2070 ke sehlahisoa sa pele letotong le lecha la li-additive silicone tse khahlanong le lerata, tse ka bang tse loketseng likoloi, lipalangoang, bareki, kaho le lisebelisoa tsa lapeng.
