Kev piav qhia

Kev txo suab nrov yog qhov teeb meem ceev hauv kev lag luam tsheb.Lub suab nrov, kev vibration thiab suab vibration (NVH) nyob rau hauv lub cockpit yog qhov tseem ceeb nyob rau hauv ultra-quiet electric tsheb.Peb cia siab tias lub cabin ua lub vaj kaj siab rau kev lom zem thiab kev lom zem.Cov tsheb tsav tus kheej xav tau ib puag ncig nyob ntsiag to.

Ntau yam khoom siv hauv tsheb dashboards, nruab nrab consoles thiab trim strips yog ua los ntawm polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) alloy.Thaum ob qhov chaw txav mus rau ib leeg (cov nyhuv nplaum nplaum), kev sib txhuam thiab kev co yuav ua rau cov ntaub ntawv no ua suab nrov.Cov kev daws teeb meem nrov nrov suav nrog cov ntawv thov thib ob ntawm kev xav, xim lossis roj nplua nyeem, thiab tshwj xeeb cov suab nrov txo cov resins.Thawj qhov kev xaiv yog ntau txheej txheem, tsis tshua muaj txiaj ntsig thiab tiv thaiv lub suab nrov tsis ruaj khov, thaum qhov kev xaiv thib ob yog kim heev.

Silike's anti-squaking masterbatch yog ib qho tshwj xeeb polysiloxane uas muab kev ua tau zoo ruaj khov los tiv thaiv squeaking rau PC / ABS qhov chaw ntawm tus nqi qis.Txij li thaum cov khoom siv los tiv thaiv squeaking tau koom ua ke thaum lub sij hawm sib xyaw lossis kev txhaj tshuaj molding, tsis tas yuav tsum tau ua cov kauj ruam tom qab uas ua rau qeeb qeeb ntawm kev tsim khoom.Nws yog ib qho tseem ceeb uas SILIPLAS 2070 masterbatch tswj cov khoom siv kho tshuab ntawm PC / ABS alloy-nrog rau nws cov kev cuam tshuam tsis zoo.Los ntawm kev nthuav dav tsim kev ywj pheej, cov thev naus laus zis tshiab no tuaj yeem tau txais txiaj ntsig OEMs tsheb thiab txhua qhov chaw ntawm lub neej.Yav dhau los, vim tias tom qab ua tiav, kev tsim cov qauv tsim tau nyuaj los yog tsis yooj yim sua kom ua tiav cov txheej txheem tom qab ua tiav.Nyob rau hauv sib piv, silicone additives tsis tas yuav hloov kho tus tsim kom optimize lawv anti-squeaking kev ua tau zoo.Silike's SILIPLAS 2070 yog thawj cov khoom lag luam hauv cov khoom lag luam tshiab ntawm cov tshuaj tiv thaiv suab nrov silicone additives, uas tej zaum yuav haum rau tsheb, tsheb thauj mus los, cov neeg siv khoom, kev tsim kho thiab cov khoom siv hauv tsev.

Nta

•Kev ua tau zoo txo ​​suab nrov: RPN <3 (raws li VDA 230-206)

• Txo cov nplaum nplaum

• Cov yam ntxwv txo suab nrov tam sim, ntev ntev

• Tsawg coefficient ntawm kev sib txhuam (COF)

• Kev cuam tshuam tsawg kawg nkaus ntawm cov khoom tseem ceeb ntawm PC / ABS (kev cuam tshuam, modulus, lub zog, elongation)

• Kev ua tau zoo nrog tus nqi ntxiv qis (4wt%)

• Ib qho yooj yim los lis, dawb ntws hais

Cov txiaj ntsig ntawm lub suab nrov muaj feem cuam tshuam qhov tseem ceeb (RPN) cov txiaj ntsig tau pom tias thaum cov ntsiab lus ntawm SILIPLAS 2070 yog 4% (wt), RPN yog 2. RPN hauv qab 3 qhia tias lub suab nrov raug tshem tawm thiab tsis muaj kev pheej hmoo ntawm kev thov mus sij hawm ntev.

Yam Tseem Ceeb

Daim duab ntawm tus nqi mem tes hloov pauv hauv qhov kev xeem stick-slip ntawm PC / ABS tom qab ntxiv 4% SILIPLAS2070:

Nws tuaj yeem pom tau tias daim nplaum nplaum kuaj pulse tus nqi ntawm PC / ABS tom qab ntxiv 4% SILIPLAS2070 tau poob qis, thiab cov kev sim ntsuas yog V = 1mm / s, F = 10N.

Tom qab ntxiv 4% SILIPLAS2070, qhov cuam tshuam lub zog yuav tsis cuam tshuam.

Cov txiaj ntsig

• Txo cov suab nrov thiab kev co kom tsawg

• Muab COF ruaj khov thaum lub sijhawm ua haujlwm ntawm cov khoom

• Txhim kho txoj kev ywj pheej tsim los ntawm kev siv cov duab geometric nyuaj

• Ua kom yooj yim ntau lawm los ntawm kev zam kev ua haujlwm thib ob

• Tsawg npaum li cas, txhim kho kev tswj tus nqi

Daim ntawv thov teb

• Automotive sab hauv qhov chaw (trim, dashboard, console)

• Cov khoom siv hluav taws xob (lub tub yees tais) thiab cov thoob khib nyiab, tshuab ntxhua khaub ncaws, tshuab ntxhua khaub ncaws)

• Cov khoom siv hauv tsev (qhov rais thav duab), thiab lwm yam.

Lub hom phiaj cov neeg siv khoom

PC/ABS compounding cog thiab ib feem ua cov nroj tsuag

Kev siv thiab ntau npaum

Ntxiv thaum lub PC / ABS alloy yog tsim, los yog tom qab lub PC / ABS alloy yog ua, thiab ces yaj-extrusion granulated, los yog nws yuav muab ntxiv ncaj qha thiab txhaj molded (nyob rau hauv lub premise ntawm kom ntseeg tau dispersion).

Qhov pom zoo ntxiv tus nqi yog 3-8%, qhov tshwj xeeb ntxiv tus nqi tau txais raws li kev sim

Pob

25Kg / hnab, khoom siv tes ua hnab.

Cia

Thauj raws li cov tshuaj tsis muaj teeb meem.Khaws rau hauv qhov chaw txias, zoo ventilated.

Txee lub neej

Cov yam ntxwv qub tseem nyob tsis tu ncua rau 24 lub hlis txij li hnub tsim khoom, yog tias khaws cia hauv kev pom zoo.Anti-squeaking masterbatch yog ib qho tshwj xeeb polysiloxane uas muab kev ua tau zoo ruaj khov los tiv thaiv squeaking rau PC / ABS qhov chaw ntawm tus nqi qis.Txij li thaum cov khoom siv los tiv thaiv squeaking tau koom ua ke thaum lub sij hawm sib xyaw lossis kev txhaj tshuaj molding, tsis tas yuav tsum tau ua cov kauj ruam tom ntej uas ua rau qhov nrawm nrawm.Nws yog ib qho tseem ceeb uas SILIKE SILIPLAS series anti-squeaking masterbatch tswj cov khoom siv ntawm PC / ABS alloy-xws li nws cov kev cuam tshuam tsis zoo.Los ntawm kev nthuav dav tsim kev ywj pheej, cov thev naus laus zis tshiab no tuaj yeem tau txais txiaj ntsig OEMs tsheb thiab txhua qhov chaw ntawm lub neej.Yav dhau los, vim tias tom qab ua tiav, kev tsim cov qauv tsim tau nyuaj los yog tsis yooj yim sua kom ua tiav cov txheej txheem tom qab ua tiav.Nyob rau hauv sib piv, silicone additives tsis tas yuav hloov kho tus tsim kom optimize lawv anti-squeaking kev ua tau zoo.Silike's SILIPLAS 2070 yog thawj cov khoom lag luam hauv cov khoom lag luam tshiab ntawm cov tshuaj tiv thaiv suab nrov silicone additives, uas tej zaum yuav haum rau tsheb, tsheb thauj mus los, cov neeg siv khoom, kev tsim kho, thiab cov khoom siv hauv tsev.
