Incazelo

Ukunciphisa umsindo kuyinkinga ephuthumayo embonini yezimoto. Umsindo, ukudlidliza kanye nokudlidliza komsindo (NVH) ngaphakathi kwe-cockpit kugqame kakhulu ezimotweni zikagesi ezithule kakhulu. Sithemba ukuthi ikhabhini lizoba ipharadesi lokuzilibazisa nokuzijabulisa. Izimoto ezizishayelayo zidinga indawo yangaphakathi ethule.

Izingxenye eziningi ezisetshenziswa kumadeshibhodi ezimoto, kuma-console aphakathi kanye nemichilo yokuhlobisa yenziwe nge-polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) alloy. Lapho izingxenye ezimbili zihamba ngokufana (umphumela wokunamathela), ukungqubuzana kanye nokudlidliza kuzokwenza lezi zinto zikhiqize umsindo. Izixazululo zomsindo zendabuko zifaka phakathi ukusetshenziswa kwesibili kwefelt, upende noma i-lubricant, kanye nama-resin akhethekile okunciphisa umsindo. Inketho yokuqala iwukusebenzisa izinqubo eziningi, ukusebenza kahle okuphansi kanye nokungazinzi kokumelana nomsindo, kanti inketho yesibili ibiza kakhulu.

I-Silike's anti-squaking masterbatch iyi-polysiloxane ekhethekile enikeza ukusebenza okuhle kakhulu okuhlala njalo kokulwa nokucinana kwezingxenye ze-PC / ABS ngentengo ephansi. Njengoba izinhlayiya zokulwa nokucinana zifakwa ngesikhathi senqubo yokuxuba noma yokubumba ngomjovo, asikho isidingo sezinyathelo zokucubungula ngemuva ezinciphisa isivinini sokukhiqiza. Kubalulekile ukuthi i-SILIPLAS 2070 masterbatch igcine izakhiwo zemishini ze-PC/ABS alloy - kufaka phakathi ukumelana kwayo okuvamile komthelela. Ngokwandisa inkululeko yokuklama, lobu buchwepheshe obusha bungazuzisa ama-OEM ezimoto nazo zonke izindlela zokuphila. Esikhathini esidlule, ngenxa yokucubungula ngemuva, ukwakheka kwezingxenye eziyinkimbinkimbi kwaba nzima noma akunakwenzeka ukufeza ukumbozwa okuphelele ngemuva kokucubungula. Ngokuphambene nalokho, izithasiselo ze-silicone azidingi ukushintsha umklamo ukuze zithuthukise ukusebenza kwazo kokulwa nokucinana. I-Silike's SILIPLAS 2070 ingumkhiqizo wokuqala ochungechungeni olusha lwezithasiselo ze-silicone ezilwa nomsindo, ezingase zifanelekele izimoto, ezokuthutha, abathengi, ezokwakha kanye nezinto zasekhaya.

Izici

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

• Nciphisa ukushelela kwenduku

• Izici zokunciphisa umsindo ezisheshayo nezihlala isikhathi eside

• I-coefficient ephansi yokungqubuzana (i-COF)

• Umthelela omncane ezimpahleni ezibalulekile ze-PC / ABS (umthelela, i-modulus, amandla, ukunwebeka)

• Ukusebenza okuphumelelayo ngenani eliphansi lokwengeza (4wt%)

• Kulula ukuphatha, izinhlayiya ezigeleza mahhala

Imiphumela yenkomba yengozi yomsindo (RPN) ikhombisa ukuthi lapho okuqukethwe yi-SILIPLAS 2070 kungu-4% (wt), i-RPN ingu-2. I-RPN engaphansi kuka-3 ikhombisa ukuthi umsindo uyasuswa futhi akukho bungozi bokusetshenziswa kwesikhathi eside.

Amapharamitha Ayisisekelo

Igrafu yokushintsha kwenani le-pulse ekuhlolweni kwe-stick-slip kwe-PC/ABS ngemuva kokwengeza i-4% SILIPLAS2070:

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

Ngemva kokwengeza u-4% we-SILIPLAS2070, amandla omthelela ngeke athinteke.

Izinzuzo

• Nciphisa umsindo ophazamisayo kanye nokudlidliza

• Nikeza i-COF ezinzile ngesikhathi sempilo yezingxenye

• Lungiselela inkululeko yokuklama ngokusebenzisa izimo zejiyometri eziyinkimbinkimbi

• Yenza lula ukukhiqiza ngokugwema imisebenzi yesibili

• Isilinganiso esiphansi, sithuthukisa ukulawulwa kwezindleko

Inkambu yohlelo lokusebenza

• Izingxenye zangaphakathi zezimoto (ukusika, ideshibhodi, ikhonsoli)

• Izingxenye zikagesi (ithreyi yesiqandisi) kanye nethini likadoti, umshini wokuwasha, umshini wokuwasha izitsha)

• Izingxenye zokwakha (ozimele bamafasitela), njll.

Amakhasimende ahlose

Isitshalo esihlanganisa i-PC/ABS kanye nesitshalo esakha izingxenye

Ukusetshenziswa kanye nomthamo

Kungezwe lapho kwenziwa i-alloy ye-PC/ABS, noma ngemva kokuba kwenziwe i-alloy ye-PC/ABS, bese kuba yi-granulated melt-extrusion, noma ingangezwa ngqo bese ifakwa injection mold (ngaphansi kwesisekelo sokuqinisekisa ukuhlakazeka).

Inani elinconywayo lokwengeza lingu-3-8%, inani elithile lokwengeza litholakala ngokusho kokuhlolwa.

Iphakheji

25Kg/isikhwama, isikhwama sephepha lezandla.

Isitoreji

Thutha njengamakhemikhali angewona ingozi. Gcina endaweni epholile, enomoya omuhle.

Isikhathi sokuphelelwa yisikhathi

Izici zokuqala zihlala zinjalo izinyanga ezingama-24 kusukela ngosuku lokukhiqiza, uma zigcinwe endaweni yokugcina enconyiwe. I-masterbatch elwa nokucinana iyi-polysiloxane ekhethekile enikeza ukusebenza okuhle kakhulu okuhlala njalo kokulwa nokucinana kwezingxenye ze-PC / ABS ngentengo ephansi. Njengoba izinhlayiya ezilwa nokucinana zifakwa ngesikhathi senqubo yokuxuba noma yokubumba ngomjovo, asikho isidingo sezinyathelo zangemva kokucubungula ezinciphisa isivinini sokukhiqiza. Kubalulekile ukuthi i-SILIKE SILIPLAS series anti-squeaking masterbatch igcine izakhiwo zemishini ze-PC / ABS alloy - kufaka phakathi ukumelana kwayo okuvamile komthelela. Ngokwandisa inkululeko yokuklama, lobu buchwepheshe obusha bungazuzisa ama-OEM ezimoto nazo zonke izindlela zokuphila. Esikhathini esidlule, ngenxa yokucubungula ngemuva, ukwakheka kwezingxenye eziyinkimbinkimbi kwaba nzima noma akunakwenzeka ukufeza ukumbozwa okuphelele ngemuva kokucubungula. Ngokuphambene nalokho, izithasiselo ze-silicone azidingi ukushintsha umklamo ukuze zithuthukise ukusebenza kwazo kokulwa nokucinana. I-SILIPLAS 2070 kaSilike ingumkhiqizo wokuqala ochungechungeni olusha lwezithasiselo ze-silicone ezilwa nomsindo, ezingase zifanelekele izimoto, ezokuthutha, abathengi, ezokwakha kanye nezinto zikagesi zasekhaya.
