Pamene makina a chingwe amaikidwa mobisa, mumsewu wapansi kapena m'madzi omwe amatha kudziunjikira madzi, pofuna kupewa nthunzi yamadzi ndi madzi kuti asalowe muzitsulo zotetezera chingwe ndikuonetsetsa moyo wa utumiki wa chingwe, chingwecho chiyenera kutengera Radial impervious chotchinga chosanjikiza kapangidwe kake, komwe kumaphatikizapo sheath yachitsulo ndi chitsulo-pulasitiki chophatikizika m'chimake. Mtsogoleri, mkuwa, aluminiyamu ndi zitsulo zina zimagwiritsidwa ntchito ngati zitsulo zazitsulo; Tepi yopangidwa ndi zitsulo-pulasitiki ndi sheath ya polyethylene imapanga chitsulo-pulasitiki chophatikizika chachitsulo. Metal-pulasitiki composite sheathing, yomwe imadziwikanso kuti comprehensive sheathing, imadziwika ndi kufewa, kusuntha, komanso kutsekemera kwamadzi ndi kakang'ono kwambiri kuposa pulasitiki, mphira wa mphira, yoyenera malo omwe ali ndi zofunikira zambiri zamadzimadzi, koma poyerekeza ndi zitsulo zachitsulo, zitsulo zopangidwa ndi pulasitiki. sheathing akadali ndi permeability.
Mu European sing'anga sing'anga voteji chingwe mfundo monga HD 620 S2: 2009, NF C33-226: 2016, UNE 211620: 2020, single-mbali TACHIMATA pulasitiki TACHIMATA zotayidwa zotayidwa chivundikirocho chivundikiro cha madzi zingwe mphamvu. Chitsulo chosanjikiza cha mbali imodzipulasitiki yokutidwa ndi aluminiyamu tepiimalumikizana mwachindunji ndi chishango choteteza, ndipo imagwira ntchito ngati chishango chachitsulo nthawi yomweyo. Muyeso waku Europe, ndikofunikira kuyesa mphamvu yovula pakati pa tepi ya aluminiyamu yokhala ndi pulasitiki ndi sheath ya chingwe ndikuyesa kukana kwa dzimbiri kuti muyeze kukana kwamadzi kwa chingwe; Nthawi yomweyo, ndikofunikira kuyeza kukana kwa DC kwa tepi ya aluminium yokutidwa ndi pulasitiki kuti muyese mphamvu yake yonyamula mafupipafupi apano.
1. Gulu la tepi ya pulasitiki yokutidwa ndi aluminiyamu
Malinga ndi mitundu yosiyanasiyana ya filimu ya pulasitiki yokutidwa ndi aluminiyamu gawo lapansi, akhoza kugawidwa mu mitundu iwiri ya nthawi yaitali ❖ kuyanika ndondomeko: mbali ziwiri pulasitiki TACHIMATA zotayidwa tepi ndi limodzi mbali imodzi pulasitiki yokutidwa zotayidwa tepi.
Chingwe choteteza madzi komanso choteteza chinyezi chapakati ndi otsika voteji zingwe ndi zingwe zowoneka bwino zopangidwa ndi tepi ya aluminiyamu yokhala ndi mbali ziwiri za pulasitiki ndi polyethylene, polyolefin ndi sheathing zina zimagwira ntchito ngati madzi owoneka bwino komanso kutsimikizira chinyezi. Tepi ya aluminiyamu ya pulasitiki yokhala ndi mbali imodzi imagwiritsidwa ntchito kwambiri potchingira zingwe zoyankhulirana zachitsulo.
M'miyezo ina ya ku Ulaya, kuwonjezera pa kugwiritsidwa ntchito ngati m'chimake chotchinga madzi, tepi ya aluminiyamu ya pulasitiki yokhala ndi mbali imodzi imagwiritsidwanso ntchito ngati chishango chachitsulo pazingwe zapakati pamagetsi, ndipo zotchingira za aluminiyamu zimakhala ndi phindu lodziwikiratu poyerekeza ndi zotchingira zamkuwa.
2. Longitudinal kuzimata ndondomeko ya pulasitiki TACHIMATA aluminium tepi
The longitudinal kuzimata ndondomeko ya aluminiyamu-pulasitiki gulu Mzere amatanthauza ndondomeko ya kusintha pulasitiki TACHIMATA zotayidwa tepi kuchokera pachiyambi lathyathyathya mawonekedwe chubu kudzera mndandanda wa nkhungu mapindikidwe, ndi kumanga m'mbali ziwiri za pulasitiki TACHIMATA aluminium tepi. Mphepete zake ziwiri za tepi ya aluminiyamu yokutira pulasitiki ndi yosalala komanso yosalala, m'mphepete mwake ndi omangika mwamphamvu, ndipo palibe kupukuta kwa aluminium-pulasitiki.
Njira yosinthira tepi ya aluminiyamu yokhala ndi pulasitiki kuchokera ku mawonekedwe athyathyathya kupita ku mawonekedwe a tubular imatha kuzindikirika pogwiritsa ntchito chomangira chotalikirapo chomwe chimapangidwa ndi nyanga yozungulira yotalikirapo, mzere wokhazikika komanso kufa kwa sizing. Chifaniziro choyenda chomangira chomangira chotalikirapo cha tepi ya aluminiyamu ya pulasitiki ikuwonetsedwa pachithunzi chotsatirachi. Mphepete ziwiri za tepi ya pulasitiki yokhala ndi aluminiyamu ya tubular imatha kulumikizidwa ndi njira ziwiri: kulumikizana kotentha ndi kuzizira kozizira.
(1) Njira yolumikizirana yotentha
The matenthedwe chomangira ndondomeko ndi ntchito pulasitiki wosanjikiza pulasitiki wokutira zotayidwa tepi kuti afewetse pa 70 ~ 90 ℃. Mu njira yopindika ya tepi ya aluminiyamu yokhala ndi pulasitiki, wosanjikiza wa pulasitiki wolumikizana ndi tepi ya aluminiyamu yophimbidwa ndi pulasitiki amatenthedwa pogwiritsa ntchito mfuti yamoto yotentha kapena lawi lamoto, ndipo m'mbali ziwiri za tepi ya aluminiyamu yokutidwa ndi pulasitiki amalumikizidwa pamodzi pogwiritsa ntchito kukhuthala. pambuyo kufewetsa kwa pulasitiki wosanjikiza. Matani m'mbali ziwiri za tepi ya pulasitiki yokutidwa ndi aluminiyamu mwamphamvu.
(2) Kumangirirana kozizira
The ozizira kugwirizana ndondomeko lagawidwa mitundu iwiri, mmodzi ndi kuwonjezera imfa yaitali khola pakati pa caliper kufa ndi extruder mutu, kuti pulasitiki TACHIMATA zotayidwa tepi amasunga ndi khola tubular dongosolo asanalowe mutu wa extruder. , kutuluka kwa khola kumakhala pafupi ndi kutuluka kwa phala la extruder's die core, ndipo aluminium-pulasitiki composite nthawi yomweyo imalowa mkati mwa kufa kwa extruder pambuyo pochotsa kufa kokhazikika. The extrusion kuthamanga kwa m'chimake chuma amasunga dongosolo tubular wa pulasitiki TACHIMATA zotayidwa tepi, ndi kutentha mkulu wa pulasitiki extruded softs pulasitiki wosanjikiza wa pulasitiki TACHIMATA zotayidwa tepi kumaliza ntchito yomangira. Ukadaulo uwu ndi woyenera pawiri-mbali mbali laminated pulasitiki TACHIMATA aluminium tepi, zipangizo kupanga ndi yosavuta kugwiritsa ntchito, koma kukonza nkhungu ndi zovuta, ndi pulasitiki TACHIMATA zotayidwa tepi yosavuta rebound.
Njira ina yozizira yomangirira ndikugwiritsa ntchito zomatira zomata zotentha zosungunuka, zomatira zotentha zosungunuka zosungunuka ndi makina otulutsa muutali wopindika wopindika mbali imodzi ya m'mphepete mwakunja kwa tepi ya pulasitiki yokutidwa ndi aluminium, mbali ziwiri za pulasitiki. tepi ya aluminiyamu yokutidwa kudzera pamzere wokhazikika ndi kukula kwake kumafa pambuyo pa zomatira zotentha zosungunuka. Ukadaulo uwu ndi woyenera pawiri-mbali zonse pulasitiki wokutidwa aluminiyamu tepi ndi umodzi mbali pulasitiki yokutidwa aluminiyamu tepi. Zida zake zopangira nkhungu ndi zopangira ndizosavuta kugwiritsa ntchito, koma zomangira zake zimakhudzidwa kwambiri ndi zomatira zotentha zosungunuka.
Pofuna kutsimikizira kudalirika kwa kayendetsedwe ka kayendetsedwe ka chingwe, chishango chachitsulo chiyenera kulumikizidwa ndi magetsi ndi chishango chotchinga cha chingwe, kotero tepi ya aluminiyamu ya pulasitiki yokhala ndi mbali imodzi iyenera kugwiritsidwa ntchito ngati chishango chachitsulo cha chingwe. Mwachitsanzo, njira yolumikizirana yotentha yomwe yatchulidwa mu pepala ili ndi yoyenera mbali ziwiri zokhapulasitiki yokutidwa ndi aluminiyamu tepi, pamene njira yozizira yomangirira pogwiritsa ntchito zomatira zotentha zosungunuka ndizoyenera kwambiri pa tepi ya aluminiyamu ya pulasitiki yokhala ndi mbali imodzi.
