Kanema wa Heat shrink ndi chinthu chodabwitsa chomwe chasintha momwe zinthu zimatetezedwa, kuwonetseredwa, ndikutumizidwa. Kaya ndinu eni mabizinesi omwe mukuyang'ana njira zopangira ma phukusi kapena mukungofuna kudziwa zambiri zazinthu zosiyanasiyanazi, werengani kuti mumvetsetse bwino.
Kodi Mafilimu a Heat Shrink Amagwira Ntchito Motani?
Pakatikati pake, filimu yochepetsera kutentha imapangidwa kuti ichepetse molimba mozungulira chinthu chikatenthedwa. Koma kodi izi zimachitika bwanji? Mafilimu ochepetsa kutentha amapangidwa kuchokera ku ma polima, omwe ndi maunyolo aatali a mamolekyu. Panthawi yopanga, ma polima awa amatambasulidwa ali mu semi-molt state. Kutambasula uku kumagwirizanitsa maunyolo a polima kumalo enaake, kusunga mphamvu zomwe zingatheke mkati mwa filimuyo.
Kutentha kumagwiritsidwa ntchito pa filimu yotambasulidwa kale, maunyolo a polima amapeza mphamvu zokwanira kuti ayambe kuyenda. Amamasuka ndi kubwerera ku chikhalidwe chawo chachibadwa, chodzizungulira. Chotsatira chake, filimuyo imachepa kukula, ikugwirizana kwambiri ndi mawonekedwe a mankhwala omwe amawatsekera.
Mitundu ya Mafilimu Ochepetsa Kutentha
Kanema wa PE Heat Shrink
Polyethylene imayimilira ngati mwala wapangodya m'mafilimu ochepetsa kutentha, okondweretsedwa chifukwa cha kusinthasintha kwake komanso magwiridwe antchito. Polima iyi imapezeka m'magiredi angapo, yokhala ndi polyethylene yocheperako (LDPE) ndi linear low - density polyethylene (LLDPE) yomwe ndiyofala kwambiri.
Kupitilira ma mechanical properties, PE kutentha kumachepetsa mafilimu amasonyeza chinyezi champhamvu - zotchinga mphamvu. Izi zimatchinjiriza bwino zinthu ku chinyezi - kuwonongeka komwe kumabwera nthawi yonse yosungiramo zinthu ndi zoyendera, kuteteza kukhulupirika ndi mtundu wawo.
Kanema wa PVC Heat Shrink
Kanema wa PVC wochepetsa kutentha kwanthawi yayitali wakhala wotchuka chifukwa chowonekera kwambiri, kunyezimira, komanso kuchepera. Imakulunga zinthu molimba komanso bwino, kukulitsa mawonekedwe awo owoneka bwino. Mafilimu a PVC nawonso ndi otsika mtengo poyerekeza ndi mafilimu ena. Nthawi zambiri amagwiritsidwa ntchito popaka zinthu monga zodzoladzola, zamagetsi, ndi zoseweretsa. Komabe, chifukwa PVC ili ndi chlorine, yomwe imatulutsa zinthu zovulaza ikawotchedwa, nkhawa za momwe chilengedwe chimakhudzira chachititsa kuchepa kwa kugwiritsidwa ntchito kwake m'zaka zaposachedwapa.

Ikhoza kupirira kutentha kwakukulu panthawi yomwe ikucheperachepera popanda kupunduka kapena kutaya kukhulupirika. Mafilimu a PET nthawi zambiri amagwiritsidwa ntchito popanga zinthu zomwe zimafuna chitetezo chapamwamba.Amaperekanso mpweya wabwino kwambiri komanso zolepheretsa chinyezi, zomwe zimathandiza kuwonjezera moyo wa alumali wazinthu. Kuphatikiza apo, PET imatha kugwiritsidwanso ntchito, ndikupangitsa kuti ikhale chisankho chokhazikika.
Lonse ntchito kutentha chepetsa filimu
Makampani a Chakudya ndi Chakumwa
Kanema wa Heat shrink ali ndi ntchito zambiri m'gawo lazakudya ndi zakumwa. Amagwiritsidwa ntchito kuyika zakudya zapayekha, monga zikwama zokhwasula-khwasula, zokolola zatsopano, ndi zakudya zozizira, zomwe zimalepheretsa chinyezi, mpweya, ndi kuipitsidwa, zomwe zimathandiza kuwonjezera nthawi ya alumali ya mankhwala. Kwa zakumwa, filimu yochepetsera kutentha nthawi zambiri imagwiritsidwa ntchito kusonkhanitsa mabotolo angapo kapena zitini palimodzi. Imagwiranso ntchito ngati chisindikizo chowoneka bwino pamabotolo ndi zotengera.
Zodzoladzola ndi Kusamalira Munthu
Zodzoladzola ndi zinthu zosamalira anthu, monga mabotolo a shampoo, machubu opaka milomo, ndi zinthu zosamalira khungu, zimapindula ndikugwiritsa ntchito filimu yochepetsa kutentha. Kanemayo sikuti amangoteteza zinthu zokha, komanso amapereka mwayi wowonetsa chizindikiro chowoneka bwino komanso chidziwitso chazinthu. Mafilimu apamwamba - onyezimira a mafilimu ena ochepetsa kutentha amatha kupangitsa kuti zinthu izi zikhale zowoneka bwino, zomwe zimapangitsa kuti zikhale zokopa kwa ogula.
Industrial and Production
M'mafakitale ndi kupanga, filimu yochepetsera kutentha imagwiritsidwa ntchito kuyika zida zamakina, zida, ndi zinthu za Hardware. Imateteza zinthuzi ku dzimbiri, dzimbiri, komanso kuwonongeka kwakuthupi panthawi yosungira komanso poyenda. Filimuyi ingagwiritsidwenso ntchito kusonkhanitsa ndi kukonza zigawo zingapo, kuti zikhale zosavuta kuzigwira ndi kutumiza.
Posankha filimu yochepetsera kutentha kuti mugwiritse ntchito, ndikofunika kuganizira zinthu monga mtundu wa chinthu chomwe mukulongedza, mlingo wofunikira wa chitetezo, maonekedwe omwe mukufuna, ndi malamulo aliwonse. Muyeneranso kuunika mtengo - mphamvu ya zosankha zosiyanasiyana zamakanema komanso kugwirizana kwa filimuyo ndi zida zanu zopakira.
