Kusanganiswa kweRabha ndiko kuparadzira akasiyana siyana zvakaringana muBexcess Simba rekuita Scabar? separavha. maitiro. Izvo zvinongedzo zvehunyanzvi zvehunyanzvi hwekunetseka Iyo yakakonzerwa rabara inodaidzwa kuti 'Kuwedzera Rabara ' uye kunaka kwayo kune kukosha kwakakosha pane kuenderera mberi nekugadzirisa uye chigadzirwa mhando.
1 - kuumbwa kwe neoprene
Neoprene ari emulsion Polymerization nzira yekugadzira, maitiro ekugadzira anonyanya kutora ketle inopinda polymerization. Polymerization tembiricha inodzorwa zvakanyanya kuma40-60 ℃, uye iyo yekutendeuka iyo inenge 90%. Polymerization tembiricha, iyo yekupedzisira shanduko yakanyanya kana polymerization maitiro mumhepo ichatungamira kune kuderera mune zvigadzirwa zvechigadzirwa. Iyo hama yemanyorerwe misa inogadziriswa neSulfu-Kiuram (tetraalkylmaminathaminoldisulfide) system mukugadzirwa. Iyo huru kusagadzikana kweiyo sulfum-kiurem system kushaikwa kwekugadzikana kweiyo sarufu zvisungo, ndechimwe chezvikonzero zvakakosha zvezvinhu zvekuchengetedza. Kana iyo hama yemubatanidzwa yakagadziriswa ne thiol inogona kuvandudza kuita uku. Neoprene yakasiyana neiyo general synthetic rabha, haina kushandisa Sulfu Vulcanization, asi neZinc oxide, Magnesium oxide, etc. Vulcanization.
Kuita kwekugadzirisa kwe neoprene kunoenderana nemaViscoelastic maitiro ekusavimbika rabara, uye maitiro ayo evavencoelastic ane hukama nemhando dzakasiyana siyana neipi uye tembiricha. Sezvo kusanganisa kunowanzoitwa mumamiriro ezvinyorwa kuti ashandise simba rekusimbisa kweiyo elastic mamiriro eRabha kuti afadze zvakanaka. Naizvozvo, kudzivisa pesvedzero yekushisa kwakanyanya kana kusanganisa neoprene, iyo filler inofanira kuwedzerwa nekukurumidza sezvinobvira kuitira kuti uwane imwe nhanho yekuvhenganisa mune elastic nyika. Kana kusanganisa neyekuvhura kunatsa, G-Type Neoprene inonzwa nekuchinja kwekushisa, uye tembiricha inodarika makumi manomwe Paunenge uchisangana nedenga rezvekunatsa, kugona kwayo kunofanirwa kuderedzwa nenzira kwayo, chinhu chakawanda chinozadza chinhu che1.6 chakakodzera, chinowanzo kupatsanurwa mukusanganisa kaviri, kuitira kuti uderedze tembiricha yekusanganisa. Tembiricha yekubvisa inofanira kunge yakaderera pane 100 ℃.
Neoprene mukushandiswa kwemusoro wakavhurika kusanganisa kukanganisa kwakakura, zviri nyore kuomerera kune vanofamba-famba, saka tembiricha yekusanganisa haifanire kunge iri diki, iyo roller yekumhanyisa ratio haifanire kunge yakakura. Nekuda kwekunzwa kwakasimba kune tembiricha, general-chinangwa nepoprene tembiricha kusvika ku71 Iyo elastic yenyika tembiricha ye islful-yakatemwa neoprene iri pazasi 79 Kukonamira nemuchina wakavhurika, kuitira kuti udzivise kunamatira, tembiricha inowanzo kudzorwa pa40 ~ 50 Kana kusanganisa, tanga wabatidza acid abtorbent magnesium auti kuti udzivise kupisa, uye pakupedzisira wedzera zinc oxide. Kuti uderedze kupisa kusanganisa, kabhoni dema uye mvura inonamira inogona kuwedzerwa mumabheti neimwe nzira. Stearic acid uye paraffin wax uye mamwe mabhuku ekushandisa anogona kuparadzirwa zvishoma nezvishoma, kuti abatsire kupararira, asi zvakare kudzivirira vanonamira rollers. Sulfa-inodzorwa chloroprene rabha muOpener kusanganisa nguva iri kazhinji 30% kusvika ku50% kusvika kune yakasarudzika nguva yerabha, inosanganiswa inosangana inogona kunge iri kusvika 20% ipfupi pane sulfur-stuff-inodzorwa. Kuti udzivise neoprene mumushini wekusanganisa mukuvhurwa kwekutanga kwekupisa kwakanyanya, iyo mhanyisa ratio isingasviki 1: 1.2 pazasi, iyo inotonhorera ichave iri nani. Kuderedza kugona kwekunatswa zvakare ndiyo nzira yekuchengetedza kuchengetedza uye kuparadzaniswa kwakanaka. Parizvino, iyo Domestic Sulfur-yakagadziridzwa neoprene Rubber Kunatswa Kugona Kupfuura Rubber Rubber Inofanirwa kunge isingasviki 20% kusvika 30%, kuitira kuti ishandire zvakajairika. Sezvo neoprene iri nyore kupfekesa, saka mukushandiswa kwekunatswa kwekunatsa muchina kusanganisa kunowanzoshandiswa munzira mbiri yekusanganisa. Iko kusanganisa tembiricha kunofanirwa kuve kwakaderera (tembiricha inowanzo kudzorwa pazasi pe100 Nechinetso icho Chloroprene Rubber Kusanganisa kuri nyore kuparadzira, LEENA Refiner yerudzi rwekupedzisira, '
2 - Kuwedzeredzwa kweEtrayne Propyone Rubber
Etleene Proylene Rubber anogona zvakare kuongororwa nemidziyo yekunatsa yerabha, asi nekuda kwekusanzwisisika kwetsiva, kuumba sheethiti yeturu, ndokuwedzera pepa rekuenderera mberi uyezve kuwanda kweganda rekusanganisa. Roll tembiricha yejira rekumberi 50 ~ 60 ℃, mushure me roll 60 ~ 70 ℃ yakakodzera. Epdm Rubber Deeding Order kazhinji: Raw Rubber Cover Cover-1/2 Carbon Black-1/2 carbon dema-zinc oxide (kana magnesium oxide) -Promoter-Crosslinker-inokatyamadza, yezasi pepa. Etleene Prollene Rubber haisi nyore kunyatsojeka kana kusanganisa, uye kuumbwa kwakanyanyisa kuparadzaniswa, asi izvo zvinhu zvekuzvinamatira murombo. Ethylene-procyle Rubber achisanganisa neyekuvhurwa, kazhinji tanga shandisa diki roll nguva yekuita kuti ienderere mberi mushure mezero, wedzera iyo compound, iyo tembiricha iri pakati pe60 ~ 70 ℃. Iko kusanganisa tembiricha ndeye 150 ~ 160 ℃, iyo inogona kubatsira kupararira kweiyo filler uye nyoro uye kuvandudzwa kweiyo michina. Iyo yekubhadhara mari inogona kuve 10% ~ 15% yakakwirira kupfuura mamwe mimwe midziyo yerabha.
3- Kuumbwa kweFluoroelastomer
Fluorine rabha menny menny viscossity yakakwira, yakaoma, kupokana kupisa kwechizvarwa, kusanganisa kwakawanda uye kugadzirisa kwakaoma. Kana kusanganisa fluorine rabha pamushini unonatsa, kune diki roll roll, shoma kugona, roll tembiricha kutonga pa50 ~ 60 ℃. Kusanganisa kunotanga, kutanga kuita kuti rollers inotonhorera, wedzera rubber tete pamba kaini kuti iite huwandu hwemukati Fluorine rabara zvakanyanya kuoma kushandisa iyo yekusanganisa muchina kusanganisa, asi iyo Mesheni yemhando yekusanganisa yemuchina inotonhora system ine simba, unogona kusanganisa fluorine rabha. Iyo yakavezwa rabha inofanira kuvezwa kwemaawa makumi maviri nemana isati yashandiswa, uye inofanirwa kunatswa usati washandiswa kuita kuti kuyaradzaniswe nekuvandudza iyo fluidity uye kuzvishambadza kwerabha.
