Sidee loo hagaajiyaa caabbinta heerkulka caagga?

U adkaysiga gabowga hawada kulul ama kulaylka gabowga ayaa noqonaysa mid sii kordheysa oo muhiim ah, gaar ahaan codsiyada baabuurta halkaas oo qaybaha caagga ah inta badan lagu isticmaalo meelo daboolan oo leh heerkul heer sare ah. Soosaarayaasha baabuurta waxay dareemeen cadaadis sii kordhaya si ay ugu go'aan qaataan nolol dheer oo loogu talagalay qaybahooda caagga ah. Hababka gabowga kulaylka anaerobic iyo kulka iyo sifooyinka gabowga hawadu way kala duwan yihiin. Caaggu waxa uu leeyahay iska caabin kulayl oo ka wanaagsan, laakiin waxa laga yaabaa in aanu weli u adkaysan weerarka ogsijiinta.

Fiiro gaar ah: Hab-maamuusyada imtixaanka guud waxa laga yaabaa inaanay khusayn kiis kasta oo gaar ah. Mid kasta oo ka mid ah doorsoomayaasha hagaajin kara caabbinta hawada-gabowga ama iska caabbinta kulaylka-gabowga ayaa hubaal ah inay saameynayaan guryaha kale, ha ahaato mid ka wanaagsan ama ka xun.

1. Perfluoroelastomer

Haddii maadada caagga ah looga baahan yahay inay lahaato iska caabin kulayl aad u fiican, waa inaad doorataa caag dafiye ah. Waxaa la sheegay in heerkulka isticmaalka perfluoroelastomer uu yahay ilaa 316 ℃.

2. caag Fluorine

FKM-ka caagga ah ee Fluorine wuxuu leeyahay kulayl aad u fiican, waxaana lagu isticmaali karaa heerkul dhan 260 ℃. Si aad u sii xoojiso caabbinta heerkulka sare ee caagga fluorine, waxaad u baahan tahay inaad doorato aqbalaha acid saxda ah (ashitada nuugista), sida firfircoonida hoose ee magnesium oxide, firfircoonida sare ee magnesium oxide, calcium oxide, calcium hydroxide, zinc oxide, iwm Fluoroelastomer waxqabadka hawada u adkeysiga kulaylka ee gabowga sidoo kale waa mid aad u wanaagsan, heerkulka isticmaalka wuxuu noqon karaa mid aad u sarreeya 200℃. Adigoo dooranaya bisphenol AF sida nidaamka vulcanization, caabbinta kulaylka gabowga ee caagga ayaa fiicnaan doonta. Loo isticmaalo deegaanka saliidda injiin adag, caabbinta kulaylka gabowga ee ternary fluoroelastomer laga sameeyey vinylidene fluoride, tetrafluoroethylene iyo propylene ayaa ka fiican fluoroelastomer guud. Tani waxay sabab u tahay beddelka hexafluoropropylene ee propylene ee habka polymerization.

3, HNBR

Heerarka sare ee hydrogenation-ka, ayaa si fiican u caabbinta kulaylka HNBR, sababtoo ah waxaa jira ku dhawaad ​​ma jiraan bond double unsaturated on silsiladda ugu weyn ee aan degganayn. Qaar ka mid ah HNBR-yada ayaa weli lagu sii dayn karaa baaruud sababtoo ah waxay weli leeyihiin xoogaa curaar ah oo labajibbaaran. Si kastaba ha ahaatee, haddii vulcanized leh peroxide, iska caabinta kulaylka xarunta waa la wanaajin doonaa. Caag HNBR ah, TOTM waxay siin kartaa iska caabbinta kulaylka ka wanaagsan kan DOP sababtoo ah isbeddelka hooseeya iyo miisaanka unugyaraha sare ee balaastikadan triocytyl.

4. Neoprene

Nooca W-neoprene wuxuu leeyahay iska caabin gabowga kulaylka oo ka wanaagsan nooca G-neoprene. Diphenylamine octanoate waa antioxidant ka wanaagsan neoprene, kaas oo si wax ku ool ah u hagaajin kara caabbinta kulaylka.

5. EPDM

EPDM wali waxay yeelan doontaa iska caabin kulayl wanaagsan 125 ℃ ka dib taam ku habboon. Isticmaalka peroxide vulcanized EPDM, waxay ka dhigi kartaa caagku inuu yeesho caabbinta kulaylka wanaagsan.

6. Habka wajiga uumiga uumiga viscosity hooseeya EPDM

content ethylene High iyo ultra-hoose viscosity viscosity wajiga EPDM, waxaa lagu buuxin karaa tiro badan oo buuxinaya, sababtoo ah content ethylene sare, processing uma baahna in ay ku biiraan processing ee hawada kulaylka u adkaysta gabowga xun iyo xabagta, weli ka dhigi kartaa caag leh guryaha processing wanaagsan, sidaas iska caabin ah kulaylka dhabta ah ee caag ah waa la wanaajiyey.

7. Iska ilaali isticmaalka xabagta styrene sare

Iska ilaali inaad ku darto resin sare ee styrene caagga loo isticmaalo heerkulka sare.

8. Budada Talcum

EPDM tuubada caagga ah, ku beddel 40% kaarboon madow budada talcum, taas oo hagaajin karta caabbinta gabowga kulaylka caagga. Qaar ka mid ah darajooyinka budada talcum waxay leeyihiin faa'iidooyin aad u fiican marka loo eego dhoobada la daweeyay ama aan la daweyn arrintan.

9. Balaastiijiyaha viscosity High

Balaastiijiyeyaasha dhexdooda, balaastikada viscosity-ga sare waxay siin kartaa iska caabin gabowga kulaylka wanaagsan marka loo eego balaastikada viscosity hoose. Sababtoo ah balaastigga sare ee viscosity wuxuu badanaa leeyahay miisaan sare oo kelli ah, ma fududa in la beddelo, sidaas darteed xasillooni wanaagsan iyo iska caabin kulayl wanaagsan.

10. Kufsiga saliidda abuur ee neoprene

Si loo sameeyo neoprene u yeesho adkeysi wanaagsan, saliid canola ayaa loo baahan yahay sababtoo ah waxay leedahay viscosity hooseeya, taas oo ka dhigaysa caaggu inuu yeesho hysteresis hooseeya iyo isbeddel hoose, kaas oo ka dhigi kara caaggu inuu yeesho caabbinta gabowga wanaagsan.

11. Nidaamka vulcanization EV/semi-wax ku ool ah SEV

Nidaamka vulcanization wax ku ool ah ama semi-wax ku ool ah, saamiga dardar-iyo baaruud waa sare, taas oo ah, 'kor u qaadida sare iyo baaruud hoose' nidaamka, oo leh ' baaruud in jirka' halkii baaruud hal, in nidaamka vulcanization this, saamiga bond sulfur hal iyo labalaab bond sulfur ee vulcanized bond ee nidaamka caag ka mid ah waa sare, sababtoo ah, iyo bond sulfur double waa ka sarreeyaa bond multi-sulfur, sidaas darteed, xasiloonida kulaylka caabbinta caagga ah waa la wanaajiyey iyo caabbinta gabowga kulaylka waa la wanaajiyey.

12. Zinc oxide

Nidaamka Vulcanization / sub-sulfuramide vulcanization ee caagga, oo ay ka buuxaan zinc oxide badan, waxay siin kartaa caag siyaalo gabowga kulaylka wanaagsan iyo iska caabin wanaagsan oo ka dambeeya baaruudda.

13. Peroxide vulcanized EPDM caag

Xarunta EPDM ee vulcanized peroxide, ZMTI waxaa loo doortaa sida antioxidant-ka, taas oo siin karta xarunta modules sare iyo caabbinta gabowga kulaylka.
