Zipangizo Zatsopano Zatsopano: Kanema wa Alceantur Office (gawo 1)

Pofuna kuwonjezera alumali wa zinthu monga chakudya ndi mankhwala osokoneza bongo, ambiriZipangizo ZopangiraKwa chakudya ndi mankhwala osokoneza bongo masiku ano amagwiritsa ntchito mafilimu ambiri ophatikizika. Pakadali pano, pali awiri, atatu, asanu, asanu ndi awiri, asanu ndi anayi, ndi khumi ndi asanu khumi ndi atatu a zinthu zophatikizira. Kanema wosanjikiza ndi filimu yopyapyala yopangidwa ndi zida zamapulasitiki angapo mu njira zingapo nthawi imodzi kuchokera kutsegulira kamodzi kuchokera kutsegulidwa kamodzi, komwe kungachotsere zabwino za zinthu zosiyanasiyana
Magawo ambiriMakonda afilimumakamaka opangidwa ndi ma polyolefinini. Pakadali pano, nyumba zomwe zimagwiritsidwa ntchito kawirikawiri zimaphatikizapo: Polyethylene / polyethylene ethylene vinyylene vasolymer / polyple / enoh / enoh / enoh / enoh / enoh / enoh / enoh / enoh / enoh / enoh / enoh / enoh / enoh / enoh / enoh / enoh / enoh / enoh / enoh / enzo Makulidwe amtundu uliwonse ukhoza kusinthidwa kudzera muukadaulo wopatula. Mwa kusintha makulidwe a chotchinga ndikugwiritsa ntchito zinthu zosiyanasiyana zotchinga, mafilimu osinthika ndi mitundu yosiyanasiyana yomwe ingapangidwire. Zipangizo zamagetsi zosindikizira zimathanso kubwezeretsedwanso ndikusinthidwa kuti zikwaniritse zosowa zosiyanasiyana. Mtundu wophatikizika uwu ndi unyinji wophatikizika ndi gawo lalikulu la chitukuko cha mafilimu mtsogolo.

Kusanjikiza kwambiri pakompyuta

Mapulogalamu amphaka a mitundu ya mitundu, mosasamala kuchuluka kwa zigawo, nthawi zambiri amagawidwa mkati, nthawi zambiri amagawika pamtunda, wogwirizira, komanso zomata zotengera kutengera ntchito iliyonse ya filimuyo.

Mulingo woyambira
Nthawi zambiri, zigawo zamkati komanso zakunja za mafilimu ophatikizika ziyenera kukhala ndi mphamvu yabwino komanso yopanga, ndikupanga kukonza magwiridwe antchito, ndikupanga kutentha. Iyeneranso kutentha kusindikiza magwiridwe antchito ndi magwiridwe antchito otentha, omwe ali ndi mtengo wotsika, ali ndi chithandizo chabwino komanso chokhazikika pa filimu yophatikizira, ndikudziwitsa chiwongola dzanja chonse. Zipangizo zapansi ndizo makamaka pe, pp, Eva, Pet, ndi Sal.

Kapangidwe kake
Gawo laFilimu ya ChaputalaNdilo chotchinga chotchinga, nthawi zambiri mkati mwa filimu yamitundu yambiri, makamaka pogwiritsa ntchito zotchinga zotchinga monga Evooh, ndi ziweto zofananira ndi zinthu zofanana.

Evoh (ethynene vinylledler Curolymer)
Ethynene Vinyll Coptolymer ndi zinthu za polymer zomwe zimaphatikizanso njira ya ethylene polima ndi zotchinga gasi mowa kwambiri. Zimawoneka kwambiri ndipo zili ndi gloss yabwino. Evoh ali ndi zotchinga bwino kwambiri za mipweya ndi mafuta, ndi mphamvu zabwino kwambiri, zolemetsa, kuvala kukana, kukana kwa nthawi, ndi mphamvu zapamwamba, ndi mphamvu yabwino kwambiri. Zotchinga zopinga za Engo zimatengera mawu a ethylene. Zinthu za Ethylene zikachulukirachulukira, ntchito zotchinga gasi zimachepa, koma chinyezi chosokoneza, ndipo ndizosavuta.
Zogulitsa zomwe zidapangidwa ndi zida za Evoh zimaphatikizapo nyengo, mkaka, zinthu za nyama, zotsatsa tchizi, ndi zina.

PVDC (Polyvinylidene chloride)
Polyvinylidene chloride (pvdc) ndi polymer wa vitylidene chloride (1,1-dichloro solmblene). Kutentha kwanyumba kwa homowolymer pvdc ndikotsika kuposa malo ake osungunuka, kumapangitsa kuti zitheke kusungunuka. Chifukwa chake, monga phukusi, pvdc ndi wopopera wa vitylidene chylidene chloride ndi vinyl chloride, omwe ali ndi mwayi wogwiritsa ntchito bwino, kusindikiza ndi kusindikiza bwino.
M'masiku oyambilira, amagwiritsidwa ntchito makamaka pantchito yankhondo. Mu ma 1950s, idayamba kugwiritsidwa ntchito ngati filimu yosungirako chakudya, makamaka yopanga mwachangu za ukadaulo wamakono komanso kuthamanga kwamakono, kusintha kwa chakudya, moyo wa alumali ndi moyo wa mankhwala osokoneza bongo kwambiri. PVDC imatha kupangidwa mu mafilimu opyapyala, kuchepetsa kuchuluka kwa zinthu zopangira ndi ndalama. Ndidziwikabe lero

Zomatira zosanjikiza
Chifukwa cha kuchuluka kwa osauka pakati pa utoto wapansi pa malo oyambira, ndikofunikira kuyika zigawo zina zomata pakati pa zigawo ziwirizo kuti zikhale ngati guluu ndi filimu yophatikizika ndikupanga filimu yophatikizika. Zotsatsa zomatira zimagwiritsa ntchito zomata zomata, zomwe nthawi zambiri zimagwiritsidwa ntchito polyalefin zolumikizidwa ndi ulembride andydride ndi ethylene vinyl acetate corolymer (Eva).

Mwamuna Waul Waydride Polyolefins
Mwamuna WaiC Anhydride Polyolefin amapangidwa ndikumalumikiza kwa uleldride ku Polyethylene kudzera m'matumbo oyambira, kuyambitsa magulu a polar pa polar. Ndi zomatira pakati pa zida za polar komanso zosakhala polar ndipo zimagwiritsidwa ntchito m'mafilimu ophatikizika a polypropylene ndi nylon.
Eva (Ethyne Vinyl acetate Coptolmer)
Eva imayambitsa kusinthika kwa vinyl monomer kulowa mu unyolo wonyezimira, kuchepetsa makristali a polyethylene ndi kukonza solubility ndi matenthedwe oyendetsa mafuta. Zomwe zili mu Ethylene ndi vinyl acetate mu zida zotsatira zotsatila:
① Zogulitsa zazikuluzikulu za Eva acetate zomwe zili pansipa 5% ndizotsatsa, mafilimu, mawaya ndi zingwe, etc;
Zogulitsa zazikulu za Eva ndi acetate zomwe zili mu 5% ~ 10% ndi mafilimu owonjezera, ndi zina;
Zogulitsa zazikuluzikulu za Eva ndi acetate zomwe zili pa 20% ~ 28% ndi otentha amasungunuka asungunuke ndi zokutira;
④ Zogulitsa zazikuluzikulu za Eva ndi vanyl acetate zomwe zili mu 5% ~ 45% ndi mafilimu (kuphatikiza makanema olima) ndi mapepala, zinthu zoumbidwa, zowopsa, etc.
