Nzira yekuvandudza sei kupisa kwekushisa kwerabha?
Kuramba kuchembera kwemhepo inopisa kana kuchembera kupisa kuri kuwedzera kukosha, kunyanya mumashandisirwo emotokari uko zvikamu zverabha zvinonyanya kushandiswa munzvimbo dzakavharwa dzine tembiricha yakakwira. Vagadziri vemotokari vakanzwa kuwedzera kumanikidzwa kuti vazvipire kuhupenyu hurefu hwesevhisi yezvikamu zvavo zverabha. Anaerobic kupisa kuchembera zvimiro uye kupisa nemhepo kuchembera zvimiro zvakasiyana. Iyo rabha ine nani kupisa kupisa, asi inogona kuramba isingamirire kurwiswa kweokisijeni.
Ongorora: Aya akajairwa bvunzo maprotocol anogona kusashanda kune yega yega kesi. Chero ipi zvayo yemhando inogona kuvandudza mhepo-kuchembera kuramba kana kupisa-kuchembera kuramba kunozokanganisa zvimwe zvivakwa, zvingave zviri nani kana zvakanyanya.
1. Perfluoroelastomer
Kana iyo rabha zvinhu zvichidikanwa kuve neyakanakisa kupisa kupisa, iwe unofanirwa kusarudza perfluorinated rabha. Zvinonzi tembiricha yekushandisa perfluoroelastomer inosvika 316 ℃.
2, Fluorine rabha
Fluorine rabha FKM ine yakanakisa kupisa kupisa, uye inogona kushandiswa patembiricha inosvika 260 ℃. Kuti uwedzere kusimbisa kupisa kwekushisa kwe fluorine rabha, unofanirwa kusarudza iyo yakakodzera asidhi inogamuchirwa (inomwisa asidhi), yakadai seyakaderera basa magnesium oxide, yakakwirira basa magnesium oxide, calcium oxide, calcium hydroxide, zinc oxide, etc. Nekusarudza bisphenol AF seyo vulcanization system, kupisa kwekuchembera kwerabha kunenge kuri nani. Inoshandiswa munzvimbo yakaoma injini yemafuta, kupisa kwekuchembera kweternary fluoroelastomer yakagadzirwa kubva vinylidene fluoride, tetrafluoroethylene uye propylene iri nani pane general fluoroelastomer. Izvi zvinokonzerwa nekutsiviwa kwehexafluoropropylene nepropylene mukuita kwepolymerization.
3, HNBR
Iyo yakakwirira dhigirii yehydrogenation, zviri nani kupikisa kupisa kweHNBR, nekuti panenge pasina unsaturated kaviri bond pacheni huru isina kugadzikana. Mamwe maHNBR anogona kunge achiri kupiswa nesarufa nekuti achine mamwe ma bond asina unsaturated. Zvisinei, kana yakasvibiswa neperoxide, kupisa kwekupisa kwekomboni kunovandudzwa. Kune HNBR rabha, TOTM inogona kupa zvirinani kupisa kupisa pane DOP nekuda kwekudzika-dzika uye kukwira kwemamorekuru kurema kweaya trioctyl plasticizer.
4. Neoprene
W-mhando neoprene ine nani kupisa kuchembera kuramba pane G-mhando neoprene. Diphenylamine octanoate iri nani antioxidant ye neoprene, iyo inogona kunyatso kuvandudza kupisa kupisa.
5, EPDM
EPDM icharamba iine yakanaka yekudzivirira kupisa pa125 ℃ mushure mekukwana kwakakodzera. Kushandiswa kweperoxide vulcanized EPDM, kunogona kuita kuti rabha ive nani kupisa kupisa.
6, Low viscosity vapor chikamu nzira EPDM
Yakakwira ethylene yemukati uye ultra-low viscosity vapor phase EPDM, inogona kuzadzwa nenhamba yakawanda yekuzadza, nekuda kweiyo yakakwira ethylene, kugadzirisa hakudi kujoinha kugadzirwa kwemhepo inodzivirira kupisa kuchembera kusingafadzi uye resin, ichiri kukwanisa kuita rabha ine yakanaka yekugadzirisa zvinhu, saka iyo chaiyo yekupisa kupisa kwerabha inovandudzwa.
7, Dzivisa kushandisa yakakwira styrene resin
Dzivisa kuwedzera yakakwira styrene resin kune rabha inoshandiswa mukupisa kwakanyanya.
8, Talcum hupfu
MuEPDM hose rabha, shandura 40% yekabhoni nhema ne talcum powder, iyo inogona kuvandudza kupisa kwekuchembera kwerabha. Mamwe mamakisi ehupfu hwetalcum ane zvakawanda zvakatanhamara pane ivhu rakarapwa kana risina kugadzirwa panyaya iyi.
9, High viscosity plasticizer
Pakati peplasticizers, high viscosity plasticizers inogona kupa zvirinani kupisa kuchembera kuramba pane yakaderera viscosity plasticizers. Nekuti iyo yakakwira viscosity plasticizer kazhinji ine yakakwira molecular huremu, isiri nyore kunyungudika, nekudaro kugadzikana kwakanaka uye kwakanaka kupisa kupisa.
10, Mafuta embeu yekubata neoprene
Kuti neoprene ive nekusimba kuri nani, mafuta ecanola anodiwa nekuti ane low viscosity, izvo zvinoita kuti rabha rive ne low hysteresis uye kuderera kuderera, izvo zvinogona kuita kuti rabha rive nekuramba kuchembera kwakanaka.
11, Inoshanda EV/semi-inoshanda SEV vulcanization system
Mune inoshanda kana semi-inoshanda vulcanization system, chiyero che accelerator nesarufa chakakwira, kureva, 'kukwidziridzwa kwepamusoro uye yakaderera sarufa' system, ine 'sarufa kumuviri' pachinzvimbo chesarufa imwechete, mune ino vulcanization system, chikamu cheimwe sarufa chisungo uye kaviri sulfur chisungo chepamusoro nekuda kweiyo vulcan vulcanization yerubha. system, chiyero cheimwe sulfur bond uye kaviri sulfur bond yakakwirira kudarika ye-multi-sarufa bond, saka, kugadzikana kwekupisa kwerabha kunovandudzwa uye kupisa kwekuchembera kunovandudzwa.
12, Zinc oxide
Vulcanization / sub-sulfuramide vulcanization system yerabha, yakazadzwa nekuwedzera zinc oxide, inogona kupa rabha iri nani kupisa kuchembera zvivakwa uye kuramba zvirinani kune post-sarufa.
13, Peroxide yakasvibiswa EPDM rabha
Mune peroxide vulcanized EPDM komboni, ZMTI inosarudzwa seyo antioxidant, iyo inogona kupa musanganiswa wepamusoro modulus uye kupisa kuchembera kuramba.
