Vim tias nws tsis ceev nrooj, zoo tshuaj ua haujlwm, tsis tshua muaj nqi, thiab kev ua haujlwm zoo tagnrho, polypropylene yog ib qho ntawm cov thawj cov khoom hauv tsev cov khoom siv hauv tsev. Nws noj nyiaj rau txog 30%. Nrog cov khoom ntiag tug thiab cov cuab yeej cuab tam tshiab, cov ntaub ntawv ntawm PP hauv tsev cov khoom siv kuj tau muab tso nrog cov kev cai siab dua. Lub tswv yim hloov kho PP yuav raug tsim tawm ntawm cov hauv qab no.
Ua ntej, ntsuab: dawb cov ntaub ntawv PP
Piv txwv nrog cov tshuaj txau, cov khoom siv tshuaj tsuag kuj yooj yim dua, muaj ntau tus phooj ywg zoo dua, muaj kev yoojyim, thiab muaj cov yam ntxwv zoo xws li lub siab, yooj yim molding, khib nyiab ua haujlwm, rov ua dua, thiab lwm yam. ntawm cov khoom siv hauv tsev yog nce. , tshwj xeeb yog cov tshuaj tsuag PP dawb.
Thib ob, kev ruaj ntseg: kom ua tau raws li cov khoom siv uas tsis muaj kev sib txuas ntawm cov khoom siv hluav taws xob uas hloov cov ntaub ntawv PP
Ntsib cov kev cai ntawm International Electrotechnical Commission (IEC) kom ntev siv cov ntaub ntawv muab hloov PP. Tus qauv IEC60335 hais tias 750 ° C glow-wire hu rau cov khoom siv los yog cov khoom tsis tuaj yeem ntes hluav taws li ntawm 30 feeb, los yog lub sij hawm kub hnyiab yog ≤ 5 feeb (piv txwv li GWIT ≥ 750 ° C) thiab kev tshawb nrhiav qhov muag (CTI) ≥ 250V.
Thib peb, kev noj qab haus huv: anti-dye PP, etc.
Yuav kom txo cov nqi, feem ntau ntawm cov khoom siv sab hauv ntawm cov khoom siv hauv vaj hauv tsev xws li cov cav ntxuav tais diav thiab cov kua txiv hmab txiv ntoo yog tsim los ntawm cov ntaub ntawv PP. Tom qab rov qab siv dua, lub hnab twb nkag tau yooj yim lawm. Yog vim li cas ho yog cov khoom siv sab hauv tom qab sib txuas nrog cov kua txiv hmab txiv ntoo, zaub mov seem, zaub mov noj, thiab lwm yam. Yog muaj kev lim piam ntawm qhov xim ntawm cov khoom hloov, thaum twg cov xim hloov mus rau qee yam, nws yuav tsis huv , thiab txawm tias tsis zoo rau cov khoom noj khoom haus li qhov chaw ua qias tuaj, txo qhov khoom Siv zoo. Cov nyom hau PP yuav tiv thaiv tau qhov teeb meem no.
Plaub, hnav: ntev iav fiber reinforced PP thiab micro-foam txhaj molding PP cov ntaub ntawv
Siab nruam ntev iav reinforced PP khoom: Nws muaj qhov zoo stability qhov siab, zoo meej mechanical zog, tsis tshua tsim thiab zoo heev nkees tsis kam.
Micro-foamed txhaj tshuaj molding PP khoom: hais txog polypropylene khoom raws li lub substrate, los ntawm kev txhaj tshuaj nyob rau hauv cov nyhuv ntawm roj siab, ua rau nruab nrab txheej ntawm cov khoom nrog kaw loj ntawm kaum mus rau ntau lub kaum ntawm micrometers thiab kaw micropores nrog ntom tawv ntawm ob sab. Qauv; yog li ua tiav lub hom phiaj ntawm kev txuag cov ntaub ntawv thiab qhov hnyav. Vim muaj kev ntxhov siab ntawm cov khoom siv faus-loj, cov tshuaj molding yog smoother, ntau ncaj, thiab qhov loj yog qhov ruaj khov dua. Nyob rau tib lub sij hawm, vim muaj kev txhawb nqa ntawm cov qhov micro-qhov, lub dab dej ntawm lub qhov chaw yuav ua tau zoo.
V. Functionalization: Laser paj ntaub ntawm cov ntaub ntawv PP, thiab lwm yam.
Cov cim qhia txog cov khoom siv yas, xws li cov lag luam thiab cov khoom siv, feem ntau yog tsim los ntawm kev ua lwm txoj kev xws li luam tawm, pasting ntawv, stamping, xuas nrig, thiab lwm yam. Siv cov tshuab laser marking sau cov cim ntawm cov khoom yas siab ua haujlwm ceev. Ib hom tshiab kos cim tshuab uas ua rau lub qhov khoom ntiag tug tseem ceeb ntawm cov khoom yas thiab ua rau cov cim thiab cov cim tsis yoo tuaj yeem ploj. Cov khoom yas siv laser marking tshuab siv laser kab kos ncaj qha tsim cov cim rau ntawm cov yas ntsa. Tus qauv tsim yog hloov tau thiab tsis tau lwm cov txheej txheem ua.
