Incazelo

Ukwehliswa komsindo wudaba oluphuthumayo embonini yezimoto.Umsindo, ukudlidliza kanye nokudlidliza komsindo (i-NVH) ngaphakathi kwe-cockpit ibonakala kakhulu ezimotweni zikagesi ezithule kakhulu.Sithemba ukuthi ikhabethe liba ipharadesi lokungcebeleka nokuzijabulisa.Izimoto ezizishayelayo zidinga indawo ethule yangaphakathi.

Izingxenye eziningi ezisetshenziswa kumadeshibhodi ezimoto, ama-centre consoles nama-trim strips zenziwe nge-polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) alloy.Uma izingxenye ezimbili zinyakaza ngokuqhathaniswa (umphumela we-stick-slip), ukungqubuzana nokudlidliza kuzobangela ukuthi lezi zinto zikhiqize umsindo.Izixazululo zomsindo ezijwayelekile zifaka ukusetshenziswa kwesibili kokuzwayo, upende noma okokugcoba, kanye nezinsalela ezikhethekile ezinciphisa umsindo.Inketho yokuqala yizinqubo eziningi, ukusebenza kahle okuphansi kanye nokungazinzi kokulwa nomsindo, kanti inketho yesibili ibiza kakhulu.

I-Silike's anti-squaking masterbatch iyi-polysiloxane ekhethekile ehlinzeka ngokusebenza okuhle kakhulu kokunqanda ukucwina kwezingxenye ze-PC/ABS ngezindleko eziphansi.Njengoba izinhlayiya ezilwa no-squeaking zihlanganiswa ngesikhathi sokuxuba noma ukubunjwa komjovo, asikho isidingo sezinyathelo zokucubungula emva kokucubungula ezinciphisa isivinini sokukhiqiza.Kubalulekile ukuthi i-SILIPLAS 2070 masterbatch igcine izakhiwo zemishini ye-PC/ABS ingxubevange-okuhlanganisa ukumelana kwayo komthelela okujwayelekile.Ngokwandisa inkululeko yokuklama, lobu buchwepheshe benoveli bungazuzisa ama-OEM ezimoto nayo yonke imikhakha yempilo.Esikhathini esedlule, ngenxa yokucubungula kwangemuva, ukwakheka kwengxenye eyinkimbinkimbi kwaba nzima noma akunakwenzeka ukufeza ukumbozwa okuphelele kwangemva kokucubungula.Ngokuphambene, izithasiselo ze-silicone azidingi ukuguqula idizayini ukuze zithuthukise ukusebenza kwazo okulwa nokuklolodela.I-Silike's SILIPLAS 2070 ingumkhiqizo wokuqala ochungechungeni olusha lwezithako ze-silicone ezilwa nomsindo, ezingase zilungele izimoto, ezokuthutha, abathengi, ukwakhiwa kanye nezinto zikagesi zasekhaya.

Izici

•Ukusebenza okuhle kakhulu kokunciphisa umsindo: RPN<3 (ngokwe-VDA 230-206)

• Nciphisa ukushelela kwezinti

• Izici zokunciphisa umsindo ezisheshayo, ezihlala isikhathi eside

• I-coefficient ephansi yefriction (COF)

• Umthelela omncane ezicini eziyinhloko zemishini ye-PC/ABS (umthelela, imodulus, amandla, ubude)

• Ukusebenza okuphumelelayo ngenani eliphansi elingeziwe (4wt%)

• Kulula ukuphatha, izinhlayiya ezigelezayo zamahhala

Imiphumela ye-noise risk priority index (RPN) ibonisa ukuthi uma okuqukethwe kwe-SILIPLAS 2070 kungu-4% (wt), i-RPN ingu-2. I-RPN engaphansi kwe-3 ibonisa ukuthi umsindo uphelile futhi ayikho ingozi yesicelo sesikhathi eside.

Amapharamitha ayisisekelo

Igrafu yoshintsho lwenani lokushaya kwenhliziyo ekuhlolweni kwe-stick-slip ye-PC/ABS ngemva kokwengeza u-4% SILIPLAS2070:

Kungabonakala ukuthi inani le-pulse test test-slip-slip ye-PC/ABS ngemva kokwengeza i-4% SILIPLAS2070 lehle kakhulu, futhi izimo zokuhlola ziyi-V=1mm/s, F=10N.

Ngemva kokungeza i-4% SILIPLAS2070, amandla omthelela ngeke athinteke.

Izinzuzo

• Nciphisa umsindo ophazamisayo nokudlidliza

• Nikeza i-COF ezinzile ngesikhathi sokusebenza kwezingxenye

• Lungiselela inkululeko yokuklama ngokusebenzisa izimo zejiyomethri eziyinkimbinkimbi

• Yenza kube lula ukukhiqiza ngokugwema imisebenzi yesibili

• Umthamo ophansi, thuthukisa ukulawulwa kwezindleko

Inkambu yohlelo lokusebenza

• Izingxenye zangaphakathi zezimoto (ukunquma, ideshibhodi, ikhonsoli)

• Izingxenye zikagesi (ithreyi lesiqandisi) kanye nomgqomo kadoti, umshini wokuwasha, umshini wokuwasha izitsha)

• Izingxenye zokwakha (amafreyimu amafasitela), njll.

Amakhasimende omgomo

Isitshalo esihlanganisa i-PC/ABS kanye nesitshalo esakha ingxenye

Ukusetshenziswa kanye nomthamo

Yengezwe lapho ingxubevange ye-PC/ABS yenziwe, noma ngemva kokwenziwa kwengxubevange ye-PC/ABS, bese i-ncibilika i-extrusion icwecwe, noma ingengezwa ngokuqondile futhi ibunjwe umjovo (ngaphansi kwesisekelo sokuqinisekisa ukuhlakazeka).

Inani elinconyiwe lokwengeza ngu-3-8%, inani elithile elingeziwe litholwa ngokuya ngokuhlolwa

Iphakheji

25Kg / isikhwama, isikhwama sephepha lezandla.

Isitoreji

Ezokuthutha njengamakhemikhali angeyona ingozi.Gcina endaweni epholile , engenawo umoya .

Impilo yeshelufu

Izici zangempela zihlala zingashintshile izinyanga ezingu-24 kusukela ngosuku lokukhiqiza , uma zigcinwe endaweni enconywayo.I-anti-squeaking masterbatch iyi-polysiloxane ekhethekile ehlinzeka ngokusebenza okuhle kakhulu okungapheli kokulwa nokucwina kwezingxenye ze-PC/ABS ngezindleko eziphansi.Njengoba izinhlayiya ezilwa no-squeaking zihlanganiswa ngesikhathi sokuxuba noma inqubo yokufaka umjovo, asikho isidingo sezinyathelo zokucubungula okuthunyelwe ezinciphisa isivinini sokukhiqiza.Kubalulekile ukuthi uchungechunge lwe-SILIKE SILIPLAS anti-squeaking masterbatch lugcine izakhiwo zemishini ze-PC/ABS ingxubevange-kuhlanganise nokuphikiswa komthelela okujwayelekile.Ngokwandisa inkululeko yokuklama, lobu buchwepheshe benoveli bungazuzisa ama-OEM ezimoto nayo yonke imikhakha yempilo.Esikhathini esedlule, ngenxa yokucubungula kwangemuva, ukwakheka kwengxenye eyinkimbinkimbi kwaba nzima noma akunakwenzeka ukufeza ukumbozwa okuphelele kwangemva kokucubungula.Ngokuphambene, izithasiselo ze-silicone azidingi ukuguqula idizayini ukuze zithuthukise ukusebenza kwazo okulwa nokuklolodela.I-Silike's SILIPLAS 2070 iwumkhiqizo wokuqala ochungechungeni olusha lwezithasiselo ze-silicone ezilwa nomsindo, ezingahle zilungele izimoto, ezokuthutha, abathengi, ezokwakha, nezinto zikagesi zasekhaya.
