Joang ho ntlafatsa ho hanyetsa mocheso oa rabara?
Ho hanyetsa botsofali ba moea o chesang kapa botsofali ba mocheso ho ntse ho e-ba bohlokoa haholo, haholo-holo lits'ebetsong tsa likoloi moo likarolo tsa rabara li sebelisoang haholo libakeng tse koahetsoeng ka mocheso o phahameng oa tikoloho. Baetsi ba likoloi ba utloile khatello e ntseng e eketseha ea ho itlama ho fana ka bophelo bo bolelele ba litšebeletso bakeng sa likarolo tsa bona tsa rabara. Lintho tsa ho tsofala ha mocheso oa Anaerobic le thepa ea ho tsofala ha mocheso le moea li fapane. Rabara e na le matla a ho hanyetsa mocheso, empa e ntse e ka 'na ea se ke ea mamella tlhaselo ea oksijene.
Tlhokomeliso: Liteko tsena tse akaretsang tsa liteko li kanna tsa se sebetse nyeoeng ka 'ngoe. E 'ngoe ea mefuta e fapaneng e ka ntlafatsang ho hanyetsa botsofali ba moea kapa ho hanyetsa mocheso o tla ama thepa e meng, ebang ke e ntle kapa e mpe.
1. Perfluoroelastomer
Haeba thepa ea rabara e hlokahala ho ba le mocheso o motle haholo, o lokela ho khetha rabara e nang le perfluorinated. Ho tlalehoa hore mocheso oa tšebeliso ea perfluoroelastomer o fihla ho 316 ℃.
2, rabara ea Fluorine
FKM ea rabara ea Fluorine e na le khanyetso e ntle ea mocheso, 'me e ka sebelisoa mochesong o fihlang ho 260℃. E le hore u matlafatse ka ho eketsehileng mocheso o phahameng oa ho hanyetsa rabara ea fluorine, u lokela ho khetha mokelikeli o nepahetseng oa asiti (e monyang asiti), joalo ka mosebetsi o fokolang oa magnesium oxide, mosebetsi o phahameng oa magnesium oxide, calcium oxide, calcium hydroxide, zinki oxide, joalo-joalo. Ka ho khetha bisphenol AF joalo ka sistimi ea vulcanization, ho hanyetsa botsofali ba mocheso ho tla ba betere. E sebelisoa tikolohong e matla ea oli ea enjine, khanyetso ea ho tsofala ha mocheso ea ternary fluoroelastomer e entsoeng ka vinylidene fluoride, tetrafluoroethylene le propylene e betere ho feta fluoroelastomer e akaretsang. Sena se bakoa ke ho nkeloa sebaka ha hexafluoropropylene ke propylene ts'ebetsong ea polymerization.
3, HNBR
Ha tekanyo ea hydrogenation e phahame, ho tla ba molemo ho hanyetsa mocheso oa HNBR, hobane ho na le hoo e ka bang ha ho na maqhama a mabeli a sa tsitsang holim'a ketane e kholo e sa tsitsang. Li-HNBR tse ling li ntse li ka ts'oaroa ka sebabole hobane li ntse li e-na le li-bond tse peli tse unsaturated. Leha ho le joalo, haeba vulcanized le peroxide, ho hanyetsa mocheso oa motsoako o tla ntlafala. Bakeng sa rabara ea HNBR, TOTM e ka fana ka ho hanyetsa mocheso hamolemo ho feta DOP ka lebaka la ho se tsitsehe ho tlase le boima bo phahameng ba limolek'hule tsa li-plasticizers tsena tsa trioctyl.
4. Neoprene
W-type neoprene e na le khanyetso e ntle ea ho tsofala ha mocheso ho feta G-type neoprene. Diphenylamine octanoate ke antioxidant e betere bakeng sa neoprene, e ka ntlafatsang hantle ho hanyetsa mocheso.
5, EPDM
EPDM e ntse e tla ba le khanyetso e ntle ea mocheso ho 125 ℃ kamora ho lekana hantle. Tšebeliso ea peroxide vulcanized EPDM, e ka etsa hore rabara e be le ho hanyetsa mocheso o betere.
6, Mokhoa o tlase oa viscosity mouoane mohato oa EPDM
Likahare tse phahameng tsa ethylene le EPDM ea mouoane oa ultra-low viscosity, e ka tlatsoa ka palo e kholo ea li-fillers, ka lebaka la litaba tse phahameng tsa ethylene, ts'ebetso ha e hloke ho ikopanya le ts'ebetso ea ho tsofala ha moea o thibelang mocheso o sa thabiseng le resin, e ntse e ka etsa hore rabara e be le thepa e ntle ea ho sebetsa, kahoo mocheso oa sebele oa ho hanyetsa rabara o ntlafala.
7. Qoba ho sebelisa resin e phahameng ea styrene
Qoba ho eketsa resin e phahameng ea styrene ho rabara e sebelisoang mocheso o phahameng.
8, phofo ea talcum
Ka rabara ea hose ea EPDM, nka sebaka sa 40% sa carbon black ka phofo ea talcum, e ka ntlafatsang ho hanyetsa botsofali ba mocheso oa rabara. Likarolo tse ling tsa phofo ea talcum li na le melemo e mengata e ikhethang ho feta letsopa le phekoloang kapa le sa phekoloang tabeng ena.
9, polasetiki e phahameng ea viscosity
Har'a li-plasticizers, li-plasticizers tse phahameng tsa viscosity li ka fana ka khanyetso e ntle ea mocheso ho feta li-plasticizers tse tlaase tsa viscosity. Hobane plasticizer e phahameng ea viscosity hangata e na le boima bo phahameng ba limolek'hule, ha ho bonolo ho fetoha, kahoo botsitso bo botle le ho hanyetsa mocheso o motle.
10, Oli ea peto ea peto bakeng sa neoprene
E le ho etsa hore neoprene e be le botsitso bo ntlafetseng, oli ea canola e hlokahala hobane e na le viscosity e tlaase, e leng se etsang hore rabara e be le hysteresis e tlaase le ho fokotseha ho fokolang, e leng se ka etsang hore rabara e be le khanyetso e ntle ea botsofali.
11, Sistimi e sebetsang hantle ea EV/SeV e sebetsang hantle haholo
Sistimi ea vulcanization e sebetsang hantle kapa e sa sebetseng hantle, karo-karolelano ea accelerator le sebabole e phahame, ke hore, 'tsamaiso e phahameng le sebabole se tlase' 'sebabole ho 'mele' sebakeng sa sebabole se le seng, tsamaisong ena ea vulcanization, karolo ea tlamo e le 'ngoe ea sebabole le tlamo e habeli ea sebabole e kentsoeng ka har'a rabara. Sistimi, karo-karolelano ea tlamo e le 'ngoe ea sebabole le tlamo e habeli ea sebabole e phahame ho feta ea maqhama a mangata a sebabole, ka hona, botsitso ba ho hanyetsa mocheso oa rabara bo ntlafatsoa mme ho hanyetsa botsofali ba mocheso ho ntlafatsoa.
12, Zinc oxide
Vulcanization / sub-sulfuramide vulcanization system ea rabara, e tlatsitsoeng ka zinc oxide e ngata, e ka fa rabara thepa e tsofalang ea mocheso le ho hanyetsa hantle ka mor'a sulfur.
13, rabara ea EPDM e nang le peroxide vulcanized
Ka har'a motsoako oa peroxide vulcanized EPDM, ZMTI e khethoa e le antioxidant, e ka fanang ka motsoako o phahameng oa modulus le ho hanyetsa botsofali ba mocheso.
