1. Natural roj hmab (NR)
Nws yog cov roj hmab hydrocarbon (polyisoprene), uas muaj me me ntawm cov protein, dej, resin acid, qab zib thiab inorganic ntsev.Loj elasticity, siab tensile zog, zoo heev tsim kua muag kuj thiab hluav taws xob rwb thaiv tsev, zoo hnav tsis kam thiab drought tsis kam, zoo processability, yooj yim rau kev sib raug zoo nrog lwm cov ntaub ntawv, thiab zoo dua li feem ntau hluavtaws rubbers nyob rau hauv cov nqe lus ntawm kev ua tau zoo.Qhov tsis zoo yog qhov tsis zoo rau cov pa oxygen thiab ozone, yooj yim rau kev laus thiab deterioration;tsis zoo tiv thaivrau cov roj thiab cov kuab tshuaj, tsis tshua muaj corrosion tsis kam rau acids thiab alkalis, thiab tsis tshua muaj cua sov.Kev khiav hauj lwm kub: txog -60℃~ + 80℃.Kev tsim cov log tsheb, khau roj hmab, hoses, tapes, insulating txheej thiab sheaths ntawm cov xov hlau thiab cables, thiab lwm yamcov khoom.Nws yog tshwj xeeb tshaj yog tsim rau kev tsim cov torsional vibration eliminators, engine shock absorbers, tshuab txhawb, roj hmab-hlau ncua kev kawm ntawv Cheebtsam, diaphragms, thiab molded khoom.
cov khoom siv roj hmab
2. Styrene butadiene roj hmab (SBR)
Copolymer ntawm butadiene thiab styrene.Qhov kev ua tau zoo yog ze rau ntawm cov roj hmab ntuj.Nws yog ib tug general-purpose hluavtaws roj hmab nrog ib tug loj tso zis tam sim no.Nws yog tus cwj pwm los ntawm kev puas tsuaj, kev laus ua haujlwm thiab kub ua haujlwm siab tshaj cov roj hmab ntuj, thiab nws qhov kev ntxhib los mos yog ntau dua li cov roj hmab ntuj.Qhov tsis zoo yog: tsis tshua muaj elasticity, tsis zoo flex kuj thiab tsim kua muag;kev ua haujlwm tsis zoo, tshwj xeeb tshaj yog tsis zoo rau nws tus kheej-nplaum thiab tsis tshua muaj roj hmab roj hmab muaj zog.Kev ua haujlwm kubQhov ntau thiab tsawg: txog -50℃~+100℃.Nws yog siv los hloov cov roj hmab ntuj los ua cov log tsheb, cov ntawv roj hmab, hoses, khau roj hmab thiab lwm yam khoom siv dav dav.
3. Butadiene roj hmab (BR)
Nws yog cis-structure roj hmab tsim los ntawm polymerization ntawm butadiene.Qhov zoo yog: zoo elasticity thiab hnav tsis kam, zoo aging kuj, zoo heev kub tsis kam, tsis tshua muaj cua sov tiam nyob rau hauv dynamic load, thiab yooj yim hlau bonding.Tnws qhov tsis zoo yog qhov tsis muaj zog, ua kua muag tsis zoo, kev ua haujlwm tsis zoo thiab nws tus kheej-adhesiveness.Kev khiav hauj lwm kub: txog -60℃~+100℃.Feem ntau, nws yog siv ua ke nrog ntuj roj hmab los yog styrene-butadiene roj hmab, feem ntau yog ua rau lub log t.nyeem, conveyor siv thiab tshwj xeeb txias-resistant khoom.
4. Isoprene roj hmab (IR)
Nws yog ib hom cis-structure roj hmab ua los ntawm polymerization ntawm isoprene monomer.Cov tshuaj muaj pes tsawg leeg thiab cov qauv peb-seem zoo ib yam li cov roj hmab ntuj, thiab qhov kev ua tau zoo yog ze rau cov roj hmab ntuj, yog li nws yog hu ua hluavtaws ntuj.roj hmab.Nws muaj feem ntau ntawm qhov zoo ntawm cov roj hmab ntuj.Vim nws txoj kev laus tsis kam, cov roj hmab ntuj tau qis dua elasticity thiab lub zog dua li cov roj hmab ntuj, kev ua haujlwm tsis zoo thiab tus nqi siab dua.Kev khiav hauj lwm kub: txog -50℃~ + 100℃Nws tuaj yeem hloov cov roj hmab ntuj los ua cov log tsheb, khau roj hmab, hoses, tapes thiab lwm yam khoom siv dav dav.
5. Neoprene (CR)
Nws yog ib qho polymer tsim los ntawm emulsion polymerization ntawm chloroprene li monomer.Cov roj hmab no muaj cov tshuaj chlorine atoms hauv nws cov molecule, yog li muab piv nrog lwm cov roj hmab dav dav: nws muaj cov tshuaj tua kab mob zoo heev, ozone tsis kam, tsis-flammable, self-extinguishing tom qab hluav taws, roj tsis kam, hnyav tsis kam, acid thiab alkali tsis kam, laus thiab roj. tsis kam.Zoo nruj thiab lwm yam zoo;nws lub cev thiab cov khoom siv kho tshuab kuj zoo dua li cov roj hmab ntuj, yog li nws tuaj yeem siv los ua cov roj hmab dav dav lossis roj hmab tshwj xeeb.Lub ntsiab qhov tsis zoo yog qhov tsis zoo ntawm qhov txias txias, qhov sib nqus loj, tus nqi txheeb ze, tsis zoo hluav taws xob rwb thaiv tsev, thiab yooj yim lo, scorching, thiab pwm sticking thaum ua.Tsis tas li ntawd, cov roj hmab nyoos muaj qhov tsis zoolity thiab tsis yooj yim rau khaws cia.Kev khiav hauj lwm kub: txog -45℃~+100℃.Feem ntau yog siv los tsim cov hlua khi thiab ntau yam kev tiv thaiv npog thiab tiv thaiv npog uas yuav tsum tau muaj kev tiv thaiv ozone thiab kev laus siab;roj thiab tshuaj tiv thaivance hoses, tapes thiab tshuaj hauv ob sab phlu;nplaim-resistant roj hmab cov khoom rau underground mining, thiab ntau yam moldings Khoom, sealing rings, gaskets, adhesives, thiab lwm yam.
