EPDM (Ethylene Propylene diene Monomer) Roj Hmab
EPDM Roj HmabYog cov copolymer ntawm ethylene, propylene thiab ib qho me me ntawm peb monomer uas tsis yog tus tuag. Lub npe thoob ntiaj teb yog: etheriene propyene diene metlyiene, lossis EPDM rau luv. EPDM roj hmab tau zoo heevUV Kuj, huab cua tiv thaiv, tshav kub kub kuj, cov tshuaj tsis kam, cov tshuaj tiv thaiv hluav taws xob, elasticity, thiab lwm yam ntawm lub cev thiab cov kws kho tshuab. Cov txiaj ntsig no tsis tuaj yeem hloov los ntawm ntau lwm cov ntaub ntawv.
1. Huab Cua KujMuaj peev xwm tiv thaiv hnyav, tshav kub, dryness thiab cov av noo rau lub neej ntev, thiab muaj lub neej zoo tshaj plaws ntawm lub neej, qhov rai thiab ntaub thaiv phab ntsa.
2. Cua sov agoning resistance txhais tau tias nws tau muaj zog tiv taus cov cua kub laus. Nws tuaj yeem siv tau ntawm -40 ~ 120 ℃ rau lub sijhawm ntev. Nws tseem tuaj yeem tuav cov yam ntxwv zoo rau lub sijhawm ntev ntawm 140 ~ 150 ℃. Nws tuaj yeem tiv thaiv kom ntau kub ntawm 230 ~ 260 ℃ hauv lub sijhawm luv luv. Nws tuaj yeem ua lub luag haujlwm hauv nroog loj hauv nroog. Ncua cov nyhuv; txuas nrog kev siv cov mis tshwj xeeb,EPDM Roj Hmabmuaj ib qho zoo ib yam li ntawm -50 ° C txog 15 ° C. Lub vev xaib tsim cov chaw tsim khoom no tau tsim cov txiaj ntsig siab zoo.
3. Vim hais tiasEpdmTau zoo heev ozone kuj, nws tseem yog lub npe hu ua "cov roj hmab tawg dawb". Nws yog qhov tshwj xeeb tshaj yog siv nyob rau hauv ntau lub nroog vaj tse nrog cov khoom sib txawv ntawm cov cua thiab yog kiag li raug rau huab cua. Nws tseem yuav ua kom pom nws cov khoom lag luam zoo dua.
4. Tsis kam rau ultraviolet hluav taws xob muab kev tiv thaiv ib puag ncig rau cov tsev neeg muaj kev cia siab; Nws tuaj yeem tiv taus 60 txog 150KV voltage, thiab muaj cov corona kuj tiv thaiv zoo, hluav taws xob tawg kuj, thiab arc kuj. Tsawg kub kub elasticity, qhov kub thaum lub tensile muaj peev xwm nce 100mpa yog -58.8 ℃.
5. Vim tias nws cov khoom siv tshwj xeeb tshaj plaws, nws feem ntau siv cov khoom siv roj av, cov tsheb ciav hlau thiab lwm yam kev siv pob qij txha thiab lwm yam kev lag luam waterproof thiab lwm yam kev lag luam dej.

1. Vim tias qhov zoo ntawm cov qauv kev coj ua ntawmSilicone Roj Hmab, Nws muaj peev xwm tswj hwm kom ruaj khov nyob rau qee lub sijhawm thiab ntau yam ntsuas kub. Piv rau lwm cov khoom siv hluavtaws, cov roj hmab silicone tuaj yeem tiv taus ultra-kub muaj ntau ntawm -101 txog 316 ° C thiab tswj hwm nws cov teeb meem ntxhov siab.
2. Lwm cov khoom muaj txiaj ntsig ntawm kev kawm thoob ntiaj teb no:radiation tsis kam, tsawg heev kev cuam tshuam ntawm kev siv tshuaj tua kab mob; Kev co, yuav luag tas li tas li cov nqi sib kis thiab cov zaus ntsuas ntawm AT -50 ~ 65 ° C; zoo dua ua pa kom ntau dua li lwm cov khoom siv polymers; Dielectric lub zog 500v · KM-1; Kis tus nqi <0.1-15ωω · cm; plam lossis tswj adhesion; ablation kub 4982 ° C; qhov tsawg kawg nkaus tso pa tawm tom qab ua kev sib xyaw ua ke; Yooj yim rau daim ntawv thov nyob rau hauv cov kev tswj noj zaub mov noj; nplaim retardant thaj chaw; tsis muaj kob thiab ntxhiab tsw tau tsim; Cov Khoom Dej Tsis Muaj Dej; Kev ua haujlwm ntawm tsib lub tshuaj lom thiab kev cog phom kev kho mob.
3. Silicone Roj Hmabtuaj yeem ua rau cov khoom lag luam ntawm ntau cov xim raws li cov neeg siv khoom xav tau thiab kev kos duab.

3. TPV / TPE Thermoplastic Elastomer
Thermoplastic elastomer muaj lub cev thiab tshuab cov cuab yeej ntawm cov roj hmab vulcanized thiab cov txheej txheem ntawm cov mos mos plastics. Nws yog qhov chaw ntawm cov yas thiab roj hmab. Hais txog kev ua, nws yog hom yas; Hais txog cov khoom, nws yog hom roj hmab. Thermoplastic elastomers muaj ntau qhov zoo dua cov thermoset rubbers.
1. Qhov qis dua ntawm thermoplastic elastomer(0.9 ~ 1.1g / cm3), yog li cov nqi txuag.
2.Qis dua kev tawm dag zogThiab kev puas tsuaj zoo heev kev qaug zog tsis kam.
3. Nws tuaj yeem yog thermally welded los txhim kho cov rooj sib txoos hloov thiab sib khi.
4. Cov ntaub ntawv pov tseg (khiav tawm hauv burrs, extrusion pov tseg cov ntaub ntawv) thiab cov khoom pov tseg zaum kawg tau xa rov qab rau kev rov ua kom rov qab los, txo cov kev ua qias tuaj yeem, txo cov khoom siv paug rau ib puag ncig thiab nthuav dav. Nws yog qhov zoo tshaj plaws ntsuab thiab ib puag ncig cov khoom siv.
