I-Rubber uhlobo lwe-e-polymer ebonakalayo ephezulu, ngaphansi kwesenzo samandla amancane angaphandle, kungakhombisa izinga eliphakeme lokukhubazeka, futhi ngemuva kokuthi ibutho langaphandle lisusiwe, lingabuyela esimweni salo sokuqala. Ngenxa yokuqina okuphezulu kwerabha, kusetshenziswa kabanzi ku-cushioning, ukushaqeka, ukubopha uphawu, njll. Isicelo embonini yokuphrinta sihlanganisa ama-rolling amarabha ahlukahlukene kanye nezingubo zokucwaninga. Ngenqubekela phambili yomkhakha werabha, imikhiqizo yenjoloba iye yathuthuka ekusetshenzisweni okukodwa kwerabha yemvelo kuya ezinhlotsheni ezahlukahlukene zokwenziwa.
1. Injoloba yemvelo
IRubber yemvelo ibuswa yiRubber Hydrocarbons (PolyiSoprene), equkethe amaprotheni amancane, amanzi, ama-resin acid, ushukela nosawoti we-inorganic. Irabha yemvelo ine-elasticity enkulu, amandla aphezulu ashubile, ukumelana kwezinyembezi okuhle nokuvinjwa kwezinyembezi zikagesi, ukumelana kahle nomoya, ukuqina kwemvelo kulula ukuhlanganisa ezinye izinto zenjoloba. Ukushiyeka kwenjoloba yemvelo kungukumelana kabi komoya-mpilo kanye ne-ozone, kulula ukumguga nokuwohloka; Ukumelana okungekuhle ku-oyili nama-sol, ukumelana okuphansi kwe-acid ne-alkali, ukumelana okuphansi kokugqwala; Ukumelana nokushisa okuphansi. Uhla lokushisa olusebenzayo lwenjoloba yemvelo: cishe -60℃~ + 80℃. IRubber yemvelo isetshenziselwa ukwenza amathayi, izicathulo zenjoloba, ama-hoses, amateyipu, izingqimba ezifaka ukufakwa kanye nemigodi yezintambo nezintambo, neminye imikhiqizo ejwayelekile. Irabha yemvelo ilungele ikakhulukazi ukwakhiwa kwama-Torsional vibrate Eximinators, injini yokushaqeka, i-Machine isekela izinto zokumiswa ngensimbi, i-diaphragms, nemikhiqizo ebunjiwe.
2. SBR
I-SBR yi-copolymer ye-batiene ne-styrene. Ukusebenza kwenjoloba ye-styrene-buthadineene kusondele naleyo yerabha yemvelo, futhi njengamanje kumanje kungumkhiqizo omkhulu wenjoloba okujwayelekile kokwenziwa. Izici ze-styrene-buthadiune rubber yizona ukumelana kwayo, ukumelana nokuguga nokumelana nokushisa kudlula irabha yemvelo, futhi ukuthungwa kwaso kufana kakhulu kunerabha yemvelo. Ububi be-styrene-buthadine rubber yilena: ukuqina okuphansi, ukumelana okunempilo nokumelana nezinyembezi; Ukusebenza okungekuhle kokusebenza, ikakhulukazi amandla akhokhelayo amahle namandla enjoloba aluhlaza.

I-styrere buthadien ruble isetshenziselwa ikakhulukazi ukufaka esikhundleni senjoloba yemvelo ukwenza amathayi, amashidi enjoloba, ama-hoses, izicathulo zenjoloba neminye imikhiqizo ejwayelekile
3. I-Nitrile Rubber
I-Nitrile Rubber iyi-copolymer ye-buthadiene kanye ne-acrylonitrile. I-Nitrile Rubber ibonakala ngokumelana kwayo okuhle kakhulu kuphethiloli kanye ne-aliphhatic hydrocarbon enjoloba, e-ester ye-polysulfide enjoloba, i-acrylic ester kanye nerabha ye-fluorine, ngenkathi i-nitrile rubber iphakeme kunamanye ama-rubber anezinhloso ezijwayelekile. Ukumelana nokushisa okuhle, ukuqina komoya okuhle, gqoka ukumelana nokumelana kwamanzi, kanye nokunamathelisa okuqinile. Ububi be-nitrile rubber bumpofu ukumelana nokubanda okubandayo kanye nokumelana kwe-ozone, amandla aphansi kanye nokuqina kwe-acid, ukumelana kabi ngogesi, nokuphikiswa kabi kukagesi, kanye nokuphikiswa okungekuhle ku-polar solvents. Uhla lokushisa lwenjoloba ye-nitrile: cishe -30℃~ + 100℃. I-nitrile rubber isetshenziselwa ikakhulukazi ukukhiqiza imikhiqizo ehlukahlukene engamelana namafutha, njenge-hoses, imikhiqizo yokubopha uphawu, ama-rollings enjoloba, njll.
4. Injoloba ye-nitrile ye-hydrogenated
I-Hydrogenated Nitrile Rubber iyi-copolymer ye-buthadiene ne-acrylonitrile. I-rubber ye-nitrile ye-hydrogenated itholakala ngokugcwele noma ngokwengxenye i-hydrogerating izibopho eziphindwe kabili ku-buthadiene ye-NBR. I-hydrogenated nitrile rubber ibonakala ngamandla aphezulu emishini kanye nokumelana nokushisa komzimba, ukumelana nokushisa kungcono kune-NBR lapho kuncipha nge-peroxide, nezinye izakhiwo ziyefana ne-nitrile ruble. Ukungathandeki kwe-hydrogenated nitrile rubber yintengo yayo ephezulu. Uhla lokushisa lwenjoloba ye-nitrile ye-hydrogenated: cishe -30℃~ + 150℃. I-Hydrogenated Nitrile Rubber isetshenziselwa ikakhulukazi imikhiqizo evimbela ukuvalwa kwamafutha futhi evumayo.
5. Injoloba ye-ethylene propylene
I-Ethylene Propelene Rubber iyi-copolymer ye-ethylene ne-propenene, futhi ngokuvamile ihlukaniswe yaba yinjoloba ezimbili ze-yuan ethylene proplene ne-yuan ethylene proplene ruble. I-ethylene-propylene rubber ibonakala ngokumelana okuhle kwe-ozone, ukumelana kwe-ultraviolet, ukumelana nesimo sezulu kanye nokumelana nokuguga, ukumelana okokuqala phakathi kwama-rubber anezinhloso ezijwayelekile. I-ethylene-propylene rubber inokufakelwa okuhle kukagesi, ukumelana kwamakhemikhali, amandla okuqina komthelela, ukumelana ne-alkali kanye ne-alkali, amandla aphansi aphansi, futhi angasetshenziselwa ukugcwaliswa okuphezulu. Ukuvikelwa kokushisa kungafinyelela ku-150°C, futhi kumelana nePolar Solvents-Ketones, ama-Esters, njll. Ezinye izakhiwo ezingokomzimba nezemishini zenjoloba ye-ethylene propelene ziphansi kancane kurabha yemvelo futhi ziphakeme ku-styrene buterneene yenjoloba. Ukungathandeki kwe-ethylene-propypene rubber ukuthi kunokuzinamathela okumpofu nokunamathela, futhi akulula ukubopha. Uhla lokushisa lwenjoloba ye-ethylene propylene: cishe -50℃~ + 150℃. I-ethylene-propylene rubber isetshenziswa kakhulu njenge-line eyeding lining, ucingo kanye nokufutheka kwekhebula, i-throm hose, i-conveveror evimbela ibhande, imikhiqizo yezenzeli yemoto kanye neminye imikhiqizo yezimboni.
I-6. I-abicone rubber
I-Silicone Rubber iyi-rubber ekhethekile enama-silicon nama-athomu omoya-mpilo ku-main chain. I-Silicon Element idlala indima enkulu e-Silicone Rubber. Izici eziyinhloko zenjoloba ye-silicone zombili zokumelana nezinga lokushisa eliphakeme (kufika ku-300°C) kanye nokumelana okuphansi kokushisa (okuphansi -100°C). Njengamanje injoloba okuphezulu kakhulu okuphezulu kakhulu; Ngasikhathi sinye, irabha le-silicone linokufakelwa okuhle kukagesi futhi lizinzile ku-axidation e-axidation kanye ne-ozone. Kumelana kakhulu futhi i-cemert indert. Okubi kweRubber ye-Silicone kungamandla aphansi emishini, ukumelana kwamafutha ampofu, ukumelana nomoya, ukumelana i-alkali, kunzima ukuvuvukelana. I-Silicone Rubber Iyasebenza Lokushisa: -60℃~ + 200℃. I-Silicone Rubber ikakhulukazi isetshenziselwa ukwenza imikhiqizo ephakeme futhi ephansi yokulinganisa izinga lokuvimbela (ama-hoses, izimpawu zocingo, njll.), Kanye nokuvikelwa kwamanzi okushisa okuphezulu kanye nokufakelwa kwentambo. Ngoba akuyona-anobuthi futhi ayinambitha, irabha le-silicone nayo isetshenziswa ezimbonini zokudla kanye nezokwelapha.
7. I-Polyurethane rubber
I-Polyurethane rubber ine-elastomer eyakhiwe yi-polymerization ye-polyerester (noma i-polyther) ne-diisocyanate compounds. I-polyurethane rubber ibonakala ngokumelana kahle kwe-abrasion, okuhamba phambili phakathi kwazo zonke izinhlobo zenjoloba; I-Polyurethane ye-rubber inamandla aphezulu, ukuqina okuhle nokuphikiswa kawoyela okuhle kakhulu. I-Polyurethane rubber futhi ihle kakhulu ekumelaneni kwe-ozone, ukumelana nokuguga, kanye nokuqina komoya.
