Cov txheej txheem thoob ntiaj teb ISO 37 qhia meej meej cov kev txwv xws li lub zog tensile thiab elongation ntawm kev tawg rau cov roj hmab vulcanized. High- cov khoom zoo yuav tsum ua tau raws li qhov yuav tsum tau ua hauv qab no: lub zog tensile Ntau dua lossis sib npaug ntawm 10 MPa, elongation ntawm kev tawg Ntau dua lossis sib npaug li 300%, thiab Shore A hardness 60 ± 5. Thaum xaiv ib hom, peb qhov yuav tsum tau txiav txim siab:
1) Vulcanization ceev: ceev- hom curing (5-15 feeb) yog haum rau kev sib dhos kab ua haujlwm, thaum kho qeeb hom (1-4 teev) yog tsim rau kev sib txuas cov txheej txheem nyuaj;
2) Siv tau qhov kub thiab txias: dav dav - hom hom phiaj yog tsim rau -40℃rau +80 degree, thaum cov hom kub kub tuaj yeem ncav cuag +200℃;
3) Kev tiv thaiv ib puag ncig: zaub mov- cov khoom qib yuav tsum tau lees paub FDA, thiab cov khoom lag luam- qib yuav tsum ua raws li RoHS cov qauv.
GB / T 528-2009 "Cov Txheej Txheem Txheej Txheem Txheej Txheem rau Vulcanized Roj Hmab" Cov qauv no qhia txog kev faib tawm, kev xav tau, thiab kev sim cov roj hmab vulcanized, suav nrog cov ntsuas xws li pom, qib ntawm vulcanization, tensile lub zog, elongation ntawm tawg, hardness tom qab vulcanization, tshav kub tsis kam, txias tsis kam, roj tsis kam, thiab processability.
GB / T 1232-2005 Txoj Cai Kev Ntsuas Kev Ntsuas ntawm Vulcanized Roj Hmab Cov qauv no qhia txog cov kev cai dav dav thiab cov qauv kev sim rau cov roj hmab vulcanized, suav nrog cov qauv kev npaj, cov qauv ntsuas thiab cov txheej txheem, suav thiab tshaj tawm cov txiaj ntsig kev xeem, thiab lwm yam.
