Bungwe Limodzi Lothandizira Kumwamba

G1031 Butyl Adhesive yokhala ndi Rubber Content Mpaka 35%

Kufotokozera Kwachidule:

G1031 butyl zomatira ndi chinthu chapamwamba kwambiri cha zomatira zathu za butyl.Moyo wautumiki ukhoza kufika zaka 25 kapena kuposerapo.Ngati kukana kwanyengo kwa gawo lapansi kuli kwabwino, ntchito yopanda madzi ndi yosindikiza imatha kufikira zaka 30 kapena kupitilira apo.Zomwe zili mu rabara ya butyl ndi pafupifupi 35%.Amagwiritsidwa ntchito makamaka ngati zida zopangira zinthu zopindika zopanda madzi zomwe zimafunikira kukana kwanyengo komanso kunyowa kwambiri komanso kusindikiza kwambiri.

Butyl Rubber Formula

Mpweya wakuda:Chikoka cha inki ya kaboni pamikhalidwe ya mphira wamba wa butyl kwenikweni ndi wofanana ndi mphira wa halogenated butyl.

Chofewetsa:mphira wambiri wa butyl amagwiritsa ntchito mafuta a petroleum monga mafuta a parafini, paraffin ndi ester plasticizers monga zofewa.

G1031

White fillers:monga kaboni wakuda, zodzaza zoyera zimakhala ndi tinthu tating'onoting'ono, mphamvu yolimbikitsira, ndi mphamvu zazikulu zamakomedwe, kupsinjika kwamphamvu, kung'ambika, kuuma, ndi zina zambiri;Kukula kwakukulu kwa tinthu kumawononga kukana misozi, kukana kusinthasintha komanso kukana kuvala.

Vulcanization System:kuwonjezera pa vulcanization ya sulfure, mphira wa butyl ulinso ndi machitidwe osiyanasiyana a vulcanization, omwe amatha kusankhidwa malinga ndi ntchito zosiyanasiyana.Makamaka mphira wa halogenated butyl, imatha kutenthedwa ndi sulfure, quinone ndi utomoni kudzera m'magulu awiri ngati mphira wa diene.Komanso, akhoza vulcanized ndi zitsulo okusayidi, dithiocarbamate zitsulo mchere ndi thiourea kudzera halogen gulu, ndi peroxide vulcanization angagwiritsidwe ntchito brominated butyl rabara.

Ubwino wosintha mwamakonda:kudalira gulu laukadaulo la akatswiri, titha kusintha zinthu malinga ndi zosowa zosiyanasiyana za makasitomala.Mtundu, mawonekedwe, kukula, kutentha ndi chinyezi cha malo ogwiritsira ntchito, ndi zina zotero. Mukayika patsogolo zomwe mukufuna komanso zomwe mukufuna, tidzasintha ndondomeko ya mankhwala kuti tikwaniritse zomwe mukufuna.(ndi chiyani · up screenshot)

Makhalidwe Azinthu

Zofunikira za rabara ya butyl zimawonjezeredwa.Zinthu izi zimapezekanso mu zomatira za butyl

(1) Kutha kwa mpweya
Liwiro lobalalika la gasi mu polima limagwirizana ndi ntchito yotentha ya mamolekyu a polima.Magulu am'mbali a methyl mu unyolo wa ma molekyulu a mphira a butyl amapangidwa mokhazikika, zomwe zimalepheretsa matenthedwe a mamolekyu a polima.Chifukwa chake, mphamvu ya gasi ndiyotsika komanso kuthina kwa gasi ndikwabwino.

(2) Kutentha kwa kutentha
Ma vulcanizates a rabara a Butyl ali ndi kukana kwambiri kutentha komanso kusasinthika.Sulfur vulcanized butyl rabara ingagwiritsidwe ntchito mumlengalenga kwa nthawi yayitali pa 100 ℃ kapena kutentha pang'ono.Kutentha kwa ntchito ya utomoni vulcanized butyl rabara akhoza kufika 150 ℃ - 200 ℃.Kukalamba kwa okosijeni wamafuta a rabara ya butyl ndi ya mtundu wowonongeka, ndipo ukalamba ukufewetsa.

(3) Kuyamwa mphamvu
Kapangidwe ka mamolekyu a mphira wa butyl ndiafupi ndi zomangira ziwiri, ndipo kachulukidwe kachulukidwe kamagulu am'mbali a methyl ndi yayikulu, kotero ili ndi mawonekedwe abwino kwambiri olandirira kugwedezeka ndi mphamvu.Makhalidwe obwereranso a mphira wa butyl sapitilira 20% mkati mwa kutentha kwakukulu (- 30-50 ℃), zomwe zikuwonetsa kuti kuthekera kwa mphira wa butyl kulandira ntchito zamakina ndikopambana ma raba ena.Katundu wonyezimira wa mphira wa butyl pa liwiro lalikulu lopindika ndilokhazikika mu gawo la polyisobutylene.Pamlingo waukulu, sichimakhudzidwa ndi kutentha kwa ntchito, digiri ya unsaturation, mawonekedwe a vulcanization ndi kusintha kwa formula.Chifukwa chake, mphira wa butyl anali chida chabwino kwambiri chotsekereza mawu komanso kuchepetsa kugwedezeka panthawiyo.

(4) Malo otsika kutentha
Maonekedwe a danga la ma molekyulu a butyl rabara ndi ozungulira.Ngakhale pali magulu ambiri a methyl, gulu lililonse la methyl omwe amwazikana mbali zonse za ozungulira amasunthidwa ndi ngodya.Chifukwa chake, tcheni cha molekyulu ya mphira ya butyl ndi yofewa, yotsika kutentha kwa galasi komanso kukhazikika bwino.

(5) Ozone ndi kukalamba kukana
Kuchuluka kwa machulukidwe a mphira a butyl kumapangitsa kuti ikhale yolimbana ndi ozoni komanso kukana kukalamba kwa nyengo.Kukaniza kwa ozone ndi pafupifupi nthawi 10 kuposa mphira wachilengedwe.

(6) Kusasinthika kwa Chemical
Mapangidwe apamwamba a mphira wa butyl amapangitsa kuti azikhala ndi kusinthasintha kwakukulu kwamankhwala.Rubber wa butyl uli ndi kukana kwa dzimbiri kwa ma inorganic acid ndi ma organic acid.Ngakhale si kugonjetsedwa ndi anaikira oxidizing zidulo, monga asidi nitric ndi sulfuric acid, akhoza kukana sanali oxidizing zidulo ndi sing'anga ndende oxidizing zidulo, komanso alkali zothetsera ndi makutidwe ndi okosijeni kuchira njira.Pambuyo poviika mu 70% sulfuric acid kwa masabata 13, mphamvu ndi kutalika kwa rabara ya butyl sizinatayike, pamene ntchito za rabala zachilengedwe ndi mphira wa styrene butadiene zinachepetsedwa kwambiri.

(7) Ntchito yamagetsi
Kutchinjiriza kwamagetsi ndi kukana kwa corona kwa mphira wa butyl ndizabwino kuposa mphira wosavuta.Voliyumu resistivity ndi nthawi 10-100 kuposa ya rabara yosavuta.Dielectric constant (1kHz) ndi 2-3 ndipo mphamvu factor (100Hz) ndi 0.0026.

(8) Kuyamwa madzi
Kulowa kwamadzi kwa rabara ya butyl ndikotsika kwambiri, ndipo mayamwidwe amadzi pa kutentha koyenera ndi otsika kuposa mphira wina, ndi 1 / 10-1 / 15 yokha.
