I. Kukambirana za ku Hight Offled
Zinthu zofunda za mphira zimapangidwa ndi njira yolumala kapena yamankhwala yolumikizira ndi mphira kuti mupeze siponji ngati mafuta a mphira. Tekinoloje yagwiritsidwa ntchito kwambiri m'makampani osiyanasiyana opanga opanga, monga zisindikizo zagalimoto ndi Zisindikizo za pawindo, zokutira, malo omanga masewera, malo oteteza masewera, etc.
1, lingaliro la mphira woluma
Mtengo wotchedwa Wokondedwa womwe umakomodwanso umadziwika kuti ukadaulo wowombera wa mphira, ndikugwiritsa ntchito wothandizirana ndi kuwononga kuti athandize mphira, kotero kuti mphirawo umakhala ndi magwiridwe antchito amtunduwu. Tekinoloje iyi imagwiritsidwa ntchito kwambiri mu gawo la kupanga tsopano, ndiye njira yodziwika bwino yopangira ntchito pakali pano.
2, gulu la zinthu zotayidwa
Zogulitsa za mphira ndi chimodzi mwazinthu zopangidwa ndi zinthu zogwiritsidwa ntchito popanga, zomwe zitha kugawidwa m'mitundu iwiri ya ma microctor ndi ma pores. Ndipo mawonekedwe ofunikira amatha kugawidwa m'malo owombera ndi zinthu zosalekeza. Malinga ndi zopangira mphira zimatha kugawidwa muzogulitsa zachilengedwe m'mabuku a mphira, isoprene yovuta kupanga, sbrlene yovuta kutulutsa mphira, etc.
Chachiwiri, zinthu zofunda zopukutira ndi kusanthula
Zogulitsa za mphira ndizogwiritsidwa ntchito kwambiri m'gulu lomwe lilipoli, kupanga ndi njira zopangira ndi kuthamanga kwa ma valcanarization ndi kuthamanga kwa omwe amathandizira kuthana ndi vutoli. Ndiye kuti, zakukhosi kwa mphira kuwonjezera pa liwiro lolumikizirana pali mgwirizano pakati pa ziphale ndi kuwonongeka kwamitundu ilo, ndikuwonjezera khoma lowonjezera la mpweya kuti lipange njira yogwirizana yogwirizana.
1, kusankha kwa nkhani yayikulu
Pazinthu zopanga, nthawi zambiri zimafuna cholinga cha chinthucho kuti chisankhe matupi a sayansi, zinthuzi posankha mphamvu zofewa, zochulukirapo, komanso kusankha chilengedwe chazipatso zopangira zosozo. Pakupanga zinthu zosagwirizana ndi mafuta, kuphatikiza pakufunika kusankha rabay yanzeru ya sayansi ya sayansi, komanso kusanthula molingana ndi zinthu zina zapadera, mutha kugwiritsanso ntchito rabaji ziwiri kapena zingapo kapena mawonekedwe.
2, kusankha kwa wothandizira
Wothandizirana nawo ndiye cholumikizira kwambiri pakupanga rabaji yonse, ndipo kusankha kwake kumakhala kogwirizana kwambiri ndi luso komanso ntchito yabwino. Nthawi zambiri, magwiridwe antchito abwino a zinthu zogulira ayenera kusankha wothandizira wa sayansi ndi woyenera, komanso kuchuluka kwa wothandizirana, kugwiritsa ntchito njira zogwiritsira ntchito chitukuko chamakono. Pakadali pano, owomberawo makamaka amakhala ndi owonjezera ogulitsa komanso owombera awiri. Ogwira ntchito mosiyanasiyana amatchula sodium bicarbonate, urea, etc. Othandizira awa ali ndi maubwino owombera mwachangu komanso kutentha kwake kogwiritsira ntchito. Pamene mpweya wopangidwa ndi ukadaulo uwu pakugwiritsa ntchito makamaka kaboni ndi ammonia, ndi zina zambiri, mophweka kugwiritsira ntchito yekhayo, ndipo nthawi zambiri zimakhala zosavuta kugwiritsa ntchito yekhayo pantchito yogwiritsira ntchito.
Ntchito yapano, yomwe tagwiritsa ntchito yovuta kwambiri imakhala ndi nitrogen dicarbonamide, nitrososulfnolfonyl hydrazide ether, magnesium oxide, etc.ons Kuwonongeka kwakukulu, kuwonongeka kwa mafuta komwe kumapangidwa makamaka ndi nayitogen, kaboni dayokisi, ammonia, ndi zina zonunkhira, ndipo ngakhalenso zosungunuka. Kukula kwapamwamba kwa zinthu za mphira wopangidwa ndi wothandizila zowawa ndi zokulirapo, ndipo kuchuluka kwa shradege kulinso kwakukulu; Mukamagwiritsa ntchito wothandizila wogwirizira, wothandizila kuzengereza ali ndi asidi wa stearic, alum, etc., omwe amatha kuchepetsa kutentha kwamphamvu kwa 130 ~ 150 ~ 15 ~
3, kusankha kwa dongosolo la chiphuphu
Makina opukutira ndikofunikira kwambiri pakufufuza zinthu zogulirako, choyamba, ngakhale zofananira ndi njira yolumikizira ndi chinsinsi chopanga zinthu zopumira. Mbewu zimatha kupunthwa bwino, chinthu chofunikira kwambiri ndi kuchuluka kwa mphira ndipo kuwonongeka kwa wogwirizira kuyenera kuphatikizika kwenikweni, kapena sulfur nthawi yolumikizidwa kuposa nthawi yovuta pang'ono. Chifukwa chake, mutasankha kachitidwe ka Vulcanation, sinthani dongosolo lomwe likugwirizana kuti mufanane nacho, kapena mutasankha kachitidweko, sinthani dongosolo la chivundikiro kuti ligwirizane.
4, kusankha kolimbikitsa Filler
Carbor wakuda, silika ndi ena othandizira amatha kusintha mphamvu ndi kuuma kwa ma calcium carbonate, dongo ndi mafilimu ena amatha kusintha magwiridwe antchito a mphira ndikuchepetsa mtengo. Carbor wakuda ayenera kusankha fef ndi srf carbor wakuda, filler ayenera kusankha crubonium carbonate, dongo, ndi zina zambiri.
5, kusankha kwapulapu
Zofunikira zapulasitiki ndi: Kutulutsa kwabwino kwa pulasitiki, Mlingo wotsika, kuyamwa mwachangu ndi mphira, kusasunthika, kulibe poizoni, wopanda poizoni, wotsika mtengo komanso wosavuta kupeza. Phukusi limatha kusintha kuchuluka kwa wowonjezera wothandizirayo, kusanza ndi kuwumba kwa kuphatikiza kwa mphira. Zinthu zodulira zithovu zomwe zimafuna chithovu chachikulu, kuchuluka kwa pulasitiri yowonjezeredwa ndikokulirapo, ndikusankha kuyenderana bwino ndi pulasitiki ya mphira.
6, kusankha kwa antioxidant
Zinthu zogulira thovu zamphamvu, malo apamwamba ndi akulu, osavuta kukalamba, kuyenera kuphatikizidwa ndi antioxidants. Mfundo yosankha antioxidant ndiyabwino kwambiri, komanso sizikhudza kuwonongeka kwa wogwirizira. Mutha kusankha 4010, 264, MB ndi ma antioxidants ena, kuchuluka kwa zinthu zambiri zoposa mphira.
7, mfundo ya mphira wamoto
Kuphulika kolimba kophukira kwa chinkhupule cha mphira, mfundo ndikuwonjezeranso wothandizira pa mphira kapena kukonzanso cholumikizira, kuwonongeka kwa mphira kuti apange chinkhupule cha buluzi.
Zinthu zazikulu zomwe zimawonetsera ndikuwongolera kapangidwe ka pores ya Bubble ndi: Kuchulukitsa mpweya wowonjezera, mpweya wa mpweya ndi kuthamanga kwambiri kwa mibadwo yamagesi ndi kuthamanga kwa chiwopsezo cha mphira.
Kuti mupange zinthu zabwino za mphira, kusankha kwa mitundu yowombera ndi mtundu wa mphira ndi kiyi. Pali njira ziwiri zachindunji:
Choyamba, malinga ndi kutentha kwa kuwonongeka kusankha kutentha kwa mtengo wowombezadwe kanu ka matenda osokoneza bongo a Valcanurization kuti musinthe liwiro la olimbikitsa kuti asinthe liwiro la chiwopsezo.
Chachiwiri, pankhani ya chivundikiro kuti mudziwe kuthamanga kwa kuwonongeka, malinga ndi kusankha kwa mitundu yokhotakhota ndi kukula kwa tinthu. Kukula kwa tinthu tawonthula ndi chimodzi mwazinthu zofunikira kwambiri posankha kuthamanga kwa wothandizila. Kukula kwa tinthu kumachepa, malo ena apamwamba a tinthu timachuluka, kutentha kwa kutentha kumawonjezeka, ndipo liwiro la kuthamanga kwa mtengowo kumatha kusinthidwa ndikusankha gawo loyenerera.
Katatu Mwaukadaulo
1, magupumu
Chomwe chimakhala cha mphira wa pulasitiki ndikuphwanya ndikuwononga unyolo wa macromerolecular. Sinthani pulasitiki, kuti kusakaniza ndi kuphatikizika kwa wothandizirayo ndikosavuta kuchita. Pokonzekera kuti mafuta a rabuble, omwe ndi abwino kwambiri a mphira, ndizosavuta kupanga zopangidwa ndi mabowo a yunifolomu, kachulukidwe kakang'ono komanso kuchuluka pang'ono. Chifukwa chake, rabara yaiwisi iyenera kupukutidwa kwathunthu.
2, Kusungira
Mpira ukasakanikirana, uyenera kuyikidwa kwa nthawi yayitali, nthawi zambiri 2 ~ 4h, kotero kuti zowonjezera zosiyanasiyana zimabalalitsidwa kwathunthu mu rabara. Zowonjezera kwambiri za mphira zimamwazika, kukhazikika kwa kukula kwazogulitsa, kusalala kwa pamwamba ndi kufanana kwa thovu.
3, kutentha
Chithovu cha mphira chimakhala ndi kutentha kwambiri. Zinthu zomwezi zimabweretsa chipolopolo osiyanasiyana. Chifukwa dongosolo lozizira komanso dongosolo la chivundikiro limafunikira kutentha mosiyanasiyana, kusintha kwa kutentha kwa chivundikiro kumathandizanso kufanana ndi dongosolo la Vulcananition ndi dongosolo lovuta.
4, kupanga
Njira zokuurira za zinthu zopukutira ndi: Kutaunikira Kuumba, Kuumba, Kuumba, etc. EPDM FOSTED pochulukitsa, ndipo NBR imagwiritsidwa ntchito kwambiri poumba.
