(1)Kusungunuka pang'ono pang'onopang'ono zero halogen polyethylene (xlpe) zotchinga:
Zinthu zotchinga za Xlpe zimapangidwa ndi polyethylene (pe) ndi evayl vinyl acetate (Eva) monga owonjezera matrix, mafuta owonjezera, etc. Pambuyo pokonzanso ma jara, PE imasintha kuchokera mu mzere wozungulira mu mawonekedwe atatu, kusintha kuchokera ku ma armoplastic to the tormoctive pulasitiki.
Zingwe zolimbitsa thupi zili ndi zabwino zingapo poyerekeza ndi PO:
1. Kukana kukonzanso kwa matenthedwe, kumalimbikitsa makina pamtundu wambiri, komanso kukana kwa chilengedwe kusokonekera komanso kukalamba.
2. Kuchulukitsa kwamankhwala ndi zosungunulira mosungunulira, kuchepetsedwa kozizira, komanso kusamalira katundu wamagetsi. Kutentha kwa nthawi yayitali kumatha kufikira 125 ° C mpaka 150 ° C. Pambuyo polumikizidwa mobwerezabwereza, kutentha kwakanthawi kochepa kwa pepro kumatha kuwonjezeka mpaka 250 ° C, kulola kuti pakhale mphamvu yayikulu kwambiri ya zingwe zomwezo makulidwe amodzimodzi.
3. Zingwe zopangidwa ndi Xlpe zimawonetsanso makina oyenda bwino, osagwirizana ndi ma radiation, zomangira zam'madzi, zingwe zam'madzi, zingwe za 1E zopangira zida za nyukiliya Zomera, zowonjezera pampu pampu, ndi zingwe zotumiza mphamvu.
Mayendedwe aposachedwa mu Xlpe Kukula kwa XLPE kumaphatikizapo zinthu zolumikizidwa ndi zingwe zolumikizira zingwe, zida zopindika kwambiri zolumikizidwa ndi zotupa za ma eleradading permading-releadad polyalefin.
(2)Olumikizidwa polyproplene (xl-pp) zotchinga:
Polypropylene (ma pp), ngati pulasitiki wamba, ali ndi mapangidwe monga kulemera kolemera, mphamvu zophukira zambiri, zowononga mtengo, kuwumba kovuta, komanso kubwezeretsanso. Komabe, ili ndi malire monga mphamvu zotsika, kukana kutentha kwa kutentha, kuwonongeka kwakukulu kwa squish, kukana mphamvu pang'ono, komanso kukana kutentha kwa kutentha ndi mpweya. Zoperewera izi zathetsa ntchito yake pakugwiritsa ntchito zingwe. Ofufuzawo akhala akuyesetsa kusintha zida za polypropyylene kuti zithandizire polyproplene (xl-pp) yagonjetsedwa ndi izi.
Xl-pp yotambalala maaya amatha kukumana ndi Ul Vw-1 mayesero a Flame ndi Ul-adavotera 150 ° C mivi wa wiya. M'mabuku othandiza, Eva nthawi zambiri amaphatikizidwa ndi Pe, pvc, mas, ndi zida zina kuti asinthe magwiridwe antchito osanjikiza.
Chimodzi mwazinthu zovuta za PP yolumikizidwa ndi IRradiation ndikuti zimakhudzanso mpikisano pakati pa mapangidwe osavomerezeka kudzera m'matumbo ophatikizika ndikugwirizanitsa ma molekyulu olimbikitsidwa ndi ma molekyulu akulu. Kafukufuku wasonyeza kuti kuchuluka kwa kuwonongeka kwa zomwe zikugwirizana ndi zolumikizira za PP Irradiation pamtunda ndi pafupifupi 0.8 mukamagwiritsa ntchito eradiation yakweredwe. Kuti mukwaniritse zomwe zimachitika polumikizana ndi ma pp, oyang'anira ogwirizana amafunika kuwonjezeredwa chifukwa cholumikizira. Kuphatikiza apo, makulidwe olumikiza a mtanda ogwirizira amacheperachepera ndi kuthekera kwa mawonekedwe a elekitoni nthawi ya ma exradiation. Irradidiation imabweretsa pakupanga mpweya ndi kugunda, komwe kuli kopindulitsa pazinthu zowonda komanso kumachepetsa kugwiritsa ntchito zingwe zokhala ndi miyendo.

Monga momwe kufunikira kwa chibiliririre kumawonjezereka, kukula kwa masinga olunjika-rearday olumikizidwa mwachangu. Poyerekeza ndi pe, zomwe zimapangitsa vinyl monomers kulowa unyolo unyolo, ali ndi ma clipstardity, omwe amasinthasintha, kukana kwamphamvu, ndikugwirira ntchito kutentha. Nthawi zambiri, zinthu za Eva zimatengera zomwe zili mu vinyl acetate monomers mu makelecular unyolo. Zinthu zapamwamba za vinyl zimayambitsa kuwonekera, kusinthasintha, komanso kulimba. Eva Touni imakhala ndi luso labwino kwambiri komanso lolumikizana, ndikupangitsa kuti ikhale yotchuka mu chingwe cholumikizira cha Flamekha.
Eva Ilin ndi ma vinyl acetate zomwe zili pafupifupi 12% mpaka 24% imagwiritsidwa ntchito mu waya ndi chingwe chinsinsi. Pazolinga zenizeni, Eva nthawi zambiri imaphatikizidwa ndi pe, pvc, mas, ndi zida zina kuti asinthe magwiridwe antchito osanjikiza. Zida za Eva zimatha kulimbikitsa kupatsana kwapatali, kukonza chinsinsi pambuyo polumikizidwa.
.
Xl-EPDM ndi mtunda wopangidwa ndi Ethylene, Propylene, komanso suvarneser monomers, yopingasa kudzera kumakomoka. Zingwe za XL-EPDm zimaphatikiza zabwino za zingwe zopatsa mphamvu za polylefin ndi zingwe zofala za mphira:
1. Kusinthasintha, kukhazikika, kusamatira kutentha kwambiri, kukana kwa nthawi yayitali, ndikulimbana ndi nyengo zovuta (-60 C mpaka 125 ° C).
2.
3. Kukana ndi mafuta ndi ma evertoni ofanana ndi cholinga cha chroroprene bibulation. Itha kupangidwa pogwiritsa ntchito zida zochulukirapo zopitilira, zimapangitsa kuti zikhale zotsika mtengo.
Zingwe za XL-EPDM ili ndi mapulogalamu osiyanasiyana, kuphatikizapo koma osakhala ndi zingwe zamagetsi zotsika, zingwe zoyatsira magalimoto, zingwe zowongolera, zida zowongolera, ndi zida zamankhwala.
Zoyipa zazikulu za zingwe za xl-epdm zimaphatikizapo zovuta zoyipa komanso zomatira zomatira komanso zotsatsa zodzikongoletsera, zomwe zingakhudze pokonzanso pambuyo pake.
(5) Silicone mphir ractution
Silicone mphira wa rabani ali ndi kusinthasintha kwa ozone, zotulutsa za Corone, ndi malawi, zimapangitsa kukhala chinthu chabwino pazinthu zamagetsi. Ntchito yake yofunika kwambiri pamakampani yamagetsi ndi ya mawaya ndi zingwe. Zingwe za mphira za silika ndi zingwe zimayenerera kwambiri kuti mugwiritse ntchito kutentha kwambiri komanso malo ofunikira, okhala ndi moyo wotalikirapo poyerekeza ndi zingwe wamba. Ntchito zodziwika bwino zimaphatikizapo miteyo yambiri kutentha, omasulira, majereminor, zida zamagetsi, zingwe zamagetsi, zingwe zamagetsi pamagalimoto oyendera, komanso zingwe zowongolera.
Pakadali pano, zingwe za mphira wa siketi nthawi zambiri zimalumikizidwa pogwiritsa ntchito mphamvu zakuthambo ndi mpweya wotentha kapena wokwera kwambiri. Palinso kafukufuku wopitilira mu kugwiritsa ntchito mtengo wama elekitoni wa electoniation ya mphira wolumikizidwa ndi silika, ngakhale kuti sanafale popanga chingwe. Ndi njira zaposachedwa kwambiri muukadaulo wogwirizanitsa wa Irradiation pamtanda, zimapereka phindu lotsika, labwino kwambiri, komanso chilengedwe, zodzikongoletsera za silika. Kudzera mwa electron frow erradiation kapena ma radiation ena ogwiritsira ntchito rabay rubulation ya silika imatha kuthandizidwa ndikulola kuwongolera pakuyamwa ndi kugwirizanitsa ndalama zina.
Chifukwa chake, kugwiritsa ntchito ukadaulo wogwirizanitsa wa Irradiation pamtunda wa zida za rabara ya Sicrine ruble gwiritsitsani lonjezo mu waya ndi zingwe. Tekinolojeyi ikuyembekezeka kuchepetsa mtengo wopanga, kusintha bwino ntchito, ndikuthandizira kuchepetsa chilengedwe. Kuyesa kwamtsogolo komanso kuyeserera kwa chitukuko kumatha kuyendetsa ukadaulo wogwirizira wa irradiation kwa zida za silika, zomwe zimapangitsa kuti zigwire ntchito kwambiri pakupanga kutentha kwambiri, mawaya apamwamba kwambiri ndi zingwe m'makampani amagetsi. Izi zimathandizanso njira zodalirika komanso zolimba za madera osiyanasiyana a mapulogalamu.
