Polyethylene ndi imodzi mwa zipangizo wotchuka kwambiri kuti ntchito ngati ma CD. Izo ntchito ku mafakitale kupanga, zamalonda ndi mafakitale, ndithudi, simungakhoze kuchita popanda izo ndi wapabanja yosavuta. Pa mayesero onsewa, abwino mawonekedwe ndi makhalidwe a nkhaniyi. Izi zikhoza kukhala phukusi, ndi filimu ukonde ndipo chubu chachikulu. Mwachitsanzo, pamaso pa mfundo ntchito kuotcha malaya pulasitiki makamaka lodziwika, ndi amene angagwiritsidwe ntchito monga maziko mankhwala osungira, ndipo m'mwamba ndi zoteteza.

Cholinga ndi ukulu wa kuotcha filimu

Ntchito yaikulu ya nkhaniyi ndi kuonetsetsa kuti zikayamba chobalidwa. Mabukuwa kumathandiza mavuto zinthu zachilengedwe, wakupatsani kupulumutsa choyambirira katundu chandamale mankhwala. Tikhoza kunena kuti mavuto awa anathana osiyanasiyana yaikulu ma CD zipangizo pakati pawo osiyanasiyana womveka wa polyethylene ochiritsira. Komabe, luso kuotcha malaya woyenera snugly allocated kwa yosungirako malo, amene amalola pazipita danga yopulumutsa packagings zoyendera. Kodi akugwiritsa ntchito njira imeneyi? Choyamba, ndi kampani zikugwira kupanga ndi kugulitsa katundu chakudya. Womata ndi wandiweyani kulongedza katundu wa katundu chofunika mu gawo la mankhwala banja, mankhwala yosindikiza, malo ndi mitundu ina ya zomangira.

mitundu

Onse zipangizo kuotcha filimu zikhoza kugawidwa m'magulu atatu mwa mtundu wa zopangira ntchito. Choncho, mankhwala a polyvinyl mankhwala enaake (PVC), polyethylene (LDPE) ndi polyolefin (POF) intaneti. Mwamsanga ine ndiyenera kunena kuti kuotcha malaya PVC ndi otchuka kwambiri chifukwa kuti amakhala msinkhu chokwanira cha zikayamba kwa kusungiramo zakudya zopatsa, koma pa nthawi yomweyo sikusokoneza njira kuwombola mpweya. Kwenikweni, m'njira imeneyi, ndipo ndi Chachikulu kusiyana pakati PVC ndi polyolefin. Zipangizo POF komanso zofuna za opanga mankhwala, tcheru ndi mpweya, koma salola mpweya uliwonse ndi malowedwe.

Kumasiyana kwambiri yaitali makhalidwe ena ndi tingachipeze powerenga nkhani pulasitiki. Nthawi zambiri ntchito magulu sitolo ya mankhwala - mwachitsanzo, phukusi angapo kapena mabotolo mtolo wa mapepala pepala. Chotero kuotcha filimu yodziwika ndi mphamvu mawotchi, mphamvu yonse ndi durability.

makhalidwe a

The miyeso ndi imodzi mwa muyezo waukulu kusankha mankhwala, ngati khalidwe la ena onse a iwo ali oyenera. Choncho, filimu yopangidwa kuchokera poliolefinola m'lifupi mpukutu wa masentimita 25 mpaka 90, ndi mamvekedwe zambiri 5 cm. Mokhudzana ndi makulidwe, ndi Pankhaniyi zosiyanasiyana mu osiyanasiyana 12-25 microns. Pamodzi kutalika kwa masikono mwina kufika 1250 m. Koma m'banja wamba kumulowetsa ndi osachepera 650 m. Polyvinylchloride kuotcha ma CD wamanja ndi zochepa lonse zosiyanasiyana zamitundu. Mwachitsanzo, ukonde m'lifupi ndi kawirikawiri kuposa 60 masentimita, kutalika -. 750 mamita Koma PVC filimu losiyana mu makulidwe, kufika pa 30 microns. zipangizo pulasitiki pafupifupi chimodzimodzi kukula osiyanasiyana. Ndi kulemera kwa ubwino pafupifupi ambirife mu osiyanasiyana makilogalamu 5-10, mu nkhani ya masikono mafakitale.

katundu opaleshoni

Ngakhale pali kusiyana mu katundu pa zinthu zosiyanasiyana kutentha shrinkable, khalidwe chimafunika ndicho chimodzimodzi. Zikuphatikizapo ntchito mulingo woyenera kwambiri kukana makina, ukhondo ndi ukhondo chitetezo palibe anatambasula, komanso inertness mankhwala. Dziwani, ndi kufala kuwala lomwe lili ndi mandala kuotcha wamanja, cholinga kwa ma CD a mankhwala chakudya. Koma chachikulu khalidwe zimasiyanitsa kuotcha zipangizo za gawo onse, ndi luso optimally afanane ndi mankhwala serviced. Shrinkage pafupifupi 40-50% pansi chikhalidwe bwino anasankha magawo kutentha mankhwala.

kuchita zida shrinkage

Kuchita ntchito ya anati kutentha mankhwala, umene ndi kuchepetsa nsalu, pogwiritsa ntchito zipangizo zapadera. Izi zikhoza kukhala basi kapena theka-zodziwikiratu zida lakonzedwa kuti ntchito ndi mankhwala a kukula yeniyeni. Komanso, mayunitsi anawagawa chitsanzo kwa mandawa ndi chipinda mtundu. Njira imeneyi kulekana Mzimuyo luso ntchito modes osiyana mu mawu a mtsinje wa utumiki - kapena siriyo chidutswa. Pa kuphedwa kwa nchito imeneyi pa kuotcha malaya kwa utuluke mpweya wotentha. Chifukwa ndi chidule cha nsalu ntchito, ndipo mokwanira maonekedwe a chinthu kwa wazolongedza. Komanso, aliyense makina ali ndi njira zina za woyendetsa ntchito ndandanda. Zikuphatikizapo Mwachitsanzo, amanena ntchito ya kudula masikono.

Kodi kwambiri ndi kuotcha wamanja?

mitengo Specific kuotcha-anatsimikiza mulingo, magawo luso ndi kukhalapo kwa katundu yeniyeni filimuyo. Si nthawi zonse tidaipanga kupanga mankhwala mu magulu a mtundu wina.
