Yog hais tias koj yuav mus yuav ul94-v0 nplaim resistant epdm pib iav plua plav thiab waterproof roj hmab hauv qab hauv Suav teb, txais tos kom tau txais cov ntaub ntawv ntau ntxiv los ntawm peb lub hoobkas. Peb kuj txais customized txiav txim.
Product Description
roj hmab molded cov khoom:
EPDM yog cov roj hmab hluavtaws paub txog nws qhov tshwj xeeb tiv thaiv tshav kub, ozone, thiab huab cua. Txawm li cas los xij, tus txheej txheem EPDM yog qhov tseemceeb. Txhawm rau ua tiav UL94-V0 kev ntsuas- qib siab tshaj plaws ntawm cov nplaim hluav taws kub hnyiab hauv UL94 tus qauv rau cov ntaub ntawv yas-lub hauv paus polymer yuav tsum tau hloov kho.
Los ntawm kev tsim khoom, qhov no suav nrog kev sib xyaw ntawm cov elastomer nyoos nrog cov halogen tshwj xeeb -dawb nplaim taws retardant additives. Cov no feem ntau yog cov ntxhia dej -raws li cov khoom siv, xws li magnesium hydroxide lossis txhuas trihydrate. Thaum raug tshav kub los yog nplaim taws, cov fillers no tau txais cov tshuaj tiv thaiv endothermic, tso dej vapor uas dilutes combustible gases thiab cools cov khoom, zoo suppressing ntawm hluav taws.
Qhov kev sib tw hauv kev tsim khoom yog nyob rau hauv qhov sib piv loading. Txhawm rau ua tiav qhov kev ntsuas V0, qhov feem pua ntawm cov muab tub lim yog xav tau. Qhov no hloov cov rheology ntawm cov roj hmab compound, ua rau nws nruj thiab nyuaj rau txheej txheem. Peb pab pawg engineering yuav tsum ua tib zoo sib npaug ntawm cov qauv kom ntseeg tau tias cov khoom ua tau raws li tus qauv flammability yam tsis muaj kev cuam tshuam lub zog tensile thiab elongation zog tsim nyog rau lub hauv siab hloov tau.
Nws pib roj hmab qhov chaw:
Kev faib tawm UL94-V0 tsis yog daim ntawv lo xwb; nws yog ib qho kev ntsuas kev ua tau zoo. Rau cov khoom siv kom tsim nyog, nws yuav tsum dhau qhov kev ntsuam xyuas qhov tseeb. Hauv cov ntsiab lus tsim khoom, peb txheeb xyuas tias cov khoom ua tau raws li cov hauv qab no:
Rapid Extinguishment:Cov qauv yuav tsum tsis txhob hlawv tsis pub dhau 10 vib nas this tom qab txhua daim ntawv thov ntawm cov nplaim taws.
Tsis muaj Dripping:Cov khoom siv yuav tsum tsis txhob tsim cov nplaim taws lossis cov tee uas ua rau cov paj rwb hauv qab cov qauv.
Lub Sijhawm Hlawv Tag Nrho:Lub sijhawm sib sau ua ke thoob plaws ib pawg ntawm cov qauv yuav tsum tsis pub tshaj 50 vib nas this.
Ua tiav qhov no nrog cov roj hmab hloov tau yooj yim yog qhov nyuaj dua li cov khoom siv yas yas. Lub geometry ntawm lub hauv qab, nrog nws cov folds thiab txawv phab ntsa thicknesses, cuam tshuam li cas cua sov dissipates. Yog li ntawd, kev tswj xyuas zoo tsis yog tsuas yog kuaj cov plaques ntawm cov roj hmab, tab sis ua pov thawj qhov ua tau zoo ntawm qhov kawg molded geometry.

Lwm cov khoom tseem ceeb:
Thaum nplaim hluav taws kub hnyiab tau hais txog kev nyab xeeb, lub tshuab ua haujlwm tseem ceeb ntawm lub iav hauv qab tseem yog qhov tsis suav nrog cov khoom paug. Cov hauv qab no ua raws li lub zog sib khi ntawm lub iav txav thiab lub static console lossis hauv pem teb lauj kaub.
EPDM raug xaiv rau daim ntawv thov no vim nws qhov muaj dej tsis txaus. Nws muab kev tiv thaiv zoo tiv thaiv dej ingress, tiv thaiv corrosion ntawm kev hloov pauv mechanism. Tsis tas li ntawd, tus tsim ntawm cov convolutions (lub folds ntawm lub hauv qab) yog xam los tso cai rau qhov tsim nyog ntau yam ntawm cov lus tsa suab -axial compression thiab extension, nrog rau angular misalignment - yam tsis tsim kom muaj kev ntxhov siab uas yuav ua rau tearing.
Lub peev xwm tiv thaiv plua plav yog nyob ntawm kev ncaj ncees ntawm daim di ncauj sealing. Thaum lub sij hawm tsim khoom, peb siv siab -cov pwm precision los xyuas kom meej qhov ntev ntev ntawm cov kab thiab sab nraud. Kev ruaj ntseg haum tiv thaiv kev nkag mus ntawm silica plua plav thiab cov khib nyiab hauv txoj kev, uas ua raws li cov abrasives uas tuaj yeem hnav cov khoom sib kis ua ntej.
Cov txheej txheem tsim khoom: Compression Moulding
Kev tsim khoom ntawm UL94-V0 EPDM tshuab feem ntau siv compression molding. Cov txheej txheem pib nrog kev npaj ntawm cov khoom siv roj hmab compounded. Vim tias cov nplaim hluav taws kub hnyiab tuaj yeem muaj lub sijhawm luv luv (lub sijhawm ua ntej cov roj hmab pib kho ntxov ntxov), kev tswj qhov kub thiab txias thaum sib tov thiab tuav yog qhov tseem ceeb.
1.
Kev npaj Preform:Cov roj hmab raug txiav rau hauv qhov hnyav hnyav kom ntseeg tau tias cov pwm kab noj hniav tau sau tag nrho yam tsis muaj flash ntau, uas txo cov khib nyiab thiab kev ua haujlwm thib ob.
2.
Moulding:Cov preforms yog muab tso rau hauv rhuab pwm kab noj hniav. Nyob rau hauv siab thiab kub (feem ntau ntawm 160℃thiab 180 degree), cov sulfur los yog peroxide curing agents pib hla -txuas, tig cov roj hmab yas rau hauv cov khoom elastic.
Kev tsim hluav taws xob- cov khoom siv roj hmab tiv taus yuav tsum tau ua raws li cov txheej txheem tsis zoo. Kev hloov pauv hauv lub sijhawm kho lossis qhov kub thiab txias tuaj yeem cuam tshuam cov nplaim hluav taws kub ua haujlwm. Yog hais tias ib feem nyob rau hauv - kho, nws yuav hlawv sai heev; yog tias dhau- kho tau, nws yuav ua nkig thiab tawg nyob rau hauv lub vibration ntawm lub tsheb.
Peb ntiav batch test protocols qhov twg cov qauv los ntawm txhua qhov ntau lawm yog raug rau kev ntsuam xyuas hluav taws xob ntsug. Tsis tas li ntawd, lub cev muaj zog xws li hardness (Shore A), lub zog tensile, thiab compression teeb raug saib xyuas kom ntseeg tau tias cov hauv qab tuaj yeem tiv taus lub neej ntawm lub tsheb.
