Yas kev faib tawm los ntawm Vulcanization
Jan 23, 2016

Huab cua noo ntaus tua yas: no yam ofcuring koob yas siv lub ya raws pa. Nws feem ntau muaj roj hmab ib-componentsilicone and polyurethane, polysulfiderubber. Polymer binders uas muaj yam noob. Thiaj hnov mob dej rau saum tej cua kom cov yas formCrosslinks tua mus rau ib networkstructure. Cov av noo hauv lub ntuj kaaj quas lug asvulcanization catalysts.

Tshuaj tua cov yas: 2-tivthaiv, polyurethane, silicone, polysulfide roj hmab, roj hmab neoprene thiab epoxy cob yas ntog rau hauv pawg no yog sov tag feem ntau curingat. Ib txhia hluas tivthaiv ofneoprene thiab chlorosulfonated polyethylenesealant thiab PVC Sol paste yas xws li chaw welding rau tsheb adhesives yuav tsum addedunder cov tshuaj, cov tshuaj tiv thaiv kiag tua.

Txoj kev hloov thermal yam yas: dispersion ofplasticizer siv polyvinyl chloride cob andasphalt roj hmab yas yog cov thermal transitionof ob ntau hom tshuab. Cob Plasticizedvinyl yog ua kua ncua kev kawm ntawv hauv chav rau ib yam khoom kheej cua sov roj hmab-asphalt andhardening thiab sealing ntawm nplaum uas muaj kub-yaj lub.

Oxidative hardening cov yas: deg kom qhuav ofcaulking los yog cov yas mus iav uas yog tus typeof tus ntoo qhuav thiab semi qhuav oilbase zaub. Hom roj yuav raug refined inpolymerization, tshuab ntswg los yog chemicalmodification. Cobalt naphthenate yog siv asdriers accelerated kom qhuav ntawm tus ishardened deg hmoov txhuas ua naphthenate puab andsurface tartar manganese naphthenate hardeninside zoo.

Solidification ntawm cov yas hnyav hom: no isa kuab dawb nplaum polymers raws li yas. Pawg no intersects butyl lub ntsiab yas, siab molecular luj PIB, ib cov kawm ntawv ofpolymerization acrylate, chlorosulfonatedpolyethylene, neoprene thiab lwm cov yas lo hniav.

Yuav tsis kom qhuav zwm yas sealing: thistype ntawm cov yas yog tso cai muaj feem ntau withpolybutylene, nruab nrab molecular luj ofpolyisobutene, viscosity siab tsis-adhesivematerials xws li styrene oxide los luj roj, notvegetable roj, tshuab ib nrab ntawm cov roj drying orbutyl roj hmab los luj cov yas.
