MH: Qhov siab tshaj plaws torque (reflects crosslink ceev thiab hardness)

Tc10: Lub sij hawm Scorch (kev nyab xeeb ua qhov rais los tiv thaiv vulcanization ntxov ntxov)

Tc90: Lub sijhawm kho tau zoo (siv sijhawm rau compression molding thiab extrusion vulcanization)

Filler Dispersion Test: Tshawb xyuas cov pa roj carbon dub / silica dispersion los xyuas qhov sib xyaw ua ke, tsis muaj pob dawb thiab agglomerate

III. Environmental Aging Resistance Testing (Yuav tsum tau ua rau sab nraum zoov & siab-Tswj siv)

Kub Huab Cua Aging (GB/T 3512): Tsis tu ncua -kub raug ntawm 70/100/120/150℃rau 24/72/168 teev. Ntsuas qhov hloov pauv ntawm lub zog tensile, elongation thiab hardness tom qab kev laus los ntsuas qhov cua sov{10}} tiv taus kev pab cuam lub neej.

Ozone Aging (GB/T 7762): Tshem tawm cov hnoos qeev mus rau ozone chamber kom pom kev tawg; qhov tseem ceeb rau cov log tsheb, lub tsev weatherstripping thiab cov khoom siv roj hmab sab nraum zoov

UV Aging Test: Simulate tshav ntuj raug; siv rau lub teeb- xim roj hmab, cov hlua khi sab nrauv thiab cov khoom siv sab nraum zoov kom tiv thaiv kev tawg thiab tawg

Tsawg-Kev Ntsuas Kub Siab (GB/T 1682): Kev sim cuam tshuam ntawm -20/-40/-50℃los xyuas qhov tawg tawg; xav tau rau cov ntsaws ruaj ruaj uas tsis tshua muaj kub siv nyob rau hauv cov cheeb tsam txias sab qaum teb thiab cov khoom siv roj hmab hauv tsheb

IV. Medium Resistance Performance (Cov khoom hu rau roj, dej, Acid & Alkali Chemicals)

Liquid Immersion Swell Test (GB/T 1690) Muab cov qauv tso rau hauv cov roj, roj cav, roj hydraulic, dej, kua qaub thiab alkaline daws, sim cov ntsuas hauv qab no:

Kev hloov pauv hloov pauv, qhov hnyav hloov pauv, lub zog tensile tuav tus nqi Cov khoom siv xaiv: NBR nta cov roj ua haujlwm zoo, EPDM muaj cov roj tsis zoo, CR muaj cov roj tsis zoo.

Dej & Gas Permeability Test Dedicated rau waterproof membranes, sealing gaskets thiab diaphragms; ntsuas dej vapor kis tus nqi thiab gas kis tus nqi

V. Kev Ntsuas Kev Ua Haujlwm Tshwj Xeeb (xaiv raws li cov khoom siv kev pabcuam)

Conductive / Anti-Static Performance: Surface resistivity, ntim tsis kam (tiv thaiv- cov roj hmab zoo li qub, cov ntsaws ruaj ruaj)

Thermal Conductivity Coefficient: Thermal conductive silicone, tshav kub dissipation tsis nco nco

Suab rwb thaiv tsev & vibration damping: DMA dynamic mechanical tsom xam, damping yam

Adhesion Strength: Peel lub zog ntawm cov roj hmab thiab hlau / ntaub, steel hlua rub- tawm quab yuam (cov hlua conveyor, vibration mounts, log tsheb)

Compression Stress Relaxation: Ntev-lub sij hawm sealing siab attenuation test rau siab-kawg O-rings

Volatile Matter, Migration & Blooming Test: Rau zaub mov- qib thiab cov khoom siv hauv tsev cov roj hmab kom tsis txhob muaj nag lossis daus los ntawm qhov chaw

VI. Raw Material Testing (Tshawb xyuas rau Raw Rubber, Fillers & Additives)

Raw Rubber: Mooney viscosity, cov ntsiab lus tshauv, cov ntsiab lus tsis hloov pauv, cov ntsiab lus impurity

Fillers (Carbon Black / Silica / Calcium Carbonate): Roj nqus tus nqi, thaj chaw tshwj xeeb, pH tus nqi, cov ntsiab lus noo noo, poob ntawm qhov hluav taws kub.

Additives: Zinc oxide purity, stearic acid melting point, coupling tus neeg saib xyuas cov ntsiab lus, accelerator purity

VII. Kev faib tawm cov qauv siv feem ntau

Kev lag luam hauv tsev: GB / T National Standards (ntaus siv rau kev xa khoom hauv tsev thiab thib peb- kev xeem tog)

Export rau Europe & America: ASTM (American Standards), ISO (International General Standards)

Automotive kev lag luam: IATF16949, txhawb kev koom tes cov qauv ntawm OEMs xws li Volkswagen thiab General Motors
