Vacuum ma CD thumba mitundu, mmene kusankha bwino vakuyumu ma CD zipangizo

Zikwama zonyamula vacuumkuchokera chotchinga ntchito akhoza kugawidwa m'matumba sanali chotchinga vakuyumu, sing'anga-chotchinga zingalowe matumba ndi mkulu-chotchinga zingalowe matumba;kuchokera kumagulu ogwira ntchito, amatha kugawidwa m'matumba otsekemera otsika kutentha, matumba otsekemera otentha kwambiri, matumba otsekemera otsekemera, matumba ang'onoang'ono, matumba oyimilira ndi matumba a zipper.
Pamaso pa zinthu zosiyanasiyana ma CD ndi makhalidwe osiyana mankhwala, mmene kusankha bwino zingalowe ma CD zipangizo wakhala kwenikweni kupanga ntchito ayenera kuthetsedwa.
Momwe mungasankhirematumba onyamula vacuumzamitundu yosiyanasiyana yazinthu?
Chifukwa mankhwala osiyanasiyana ali ndi zofunika zosiyanasiyana ma CD ma CD, choncho tiyenera kusankha zinthu malinga ndi makhalidwe mankhwala, kuphatikizapo: ngati n'zosavuta kuwonongeka, zinthu zimene zimabweretsa kuwonongeka (kuwala, madzi kapena mpweya, etc.), mankhwala mawonekedwe, mankhwala pamwamba kuuma, zinthu yosungirako, yotsekereza kutentha, etc. A zabwino zingalowe thumba thumba, osati ndi mbali zambiri, koma kuona ngati ndi oyenera mankhwala.
1. Zogulitsa zokhala ndi mawonekedwe okhazikika kapena zofewa.
Pakuti mankhwala ndi wokhazikika mawonekedwe kapena pamwamba yofewa, monga mankhwala soseji nyama, mankhwala soya, etc., si koyenera amafuna mkulu mawotchi mphamvu zakuthupi, muyenera kuganizira chotchinga cha zinthu ndi mmene yolera yotseketsa kutentha. pa zinthu.Chifukwa chake, pazinthu zotere, kugwiritsidwa ntchito kwa OPA / PE kwa thumba.Ngati pakufunika kuletsa kutentha kwambiri (kuposa 100 ℃), mutha kugwiritsa ntchito mawonekedwe a OPA / CPP, kapena kugwiritsa ntchito PE yosagwirizana ndi kutentha kwambiri ngati gawo losindikiza kutentha.
2. Mankhwala okhala ndi kuuma kwakukulu.
monga mankhwala nyama ndi mafupa, chifukwa mkulu padziko kuuma ndi protrusions zolimba, zosavuta puncture thumba mu ndondomeko vakuyumu ndi zoyendera, kotero matumba a zinthu zimenezi ayenera kukhala wabwino puncture kukana ndi buffering ntchito, mukhoza kusankha PET/PA/PE kapena OPET/OPA/CPP matumba vacuum matumba.Ngati kulemera kwa mankhwala ndi zosakwana 500g, mungayesere ntchito OPA/OPA/PE dongosolo thumba, thumba ili ndi zabwino mankhwala kusinthika, zotsatira bwino zingalowe, pamene osasintha mawonekedwe a mankhwala.
3. Zowonongeka.
Otsika kutentha nyama mankhwala ndi mankhwala ena amene sachedwa kuwonongeka ndipo amafuna otsika kutentha yolera yotseketsa mphamvu ya thumba si mkulu, koma amafuna kwambiri chotchinga katundu, kotero inu mukhoza kusankha koyera co-extruded filimu, monga PA/PE /EVOH/PA/PE kapangidwe ka filimuyi, mutha kugwiritsanso ntchito kuphatikizika kowuma, monga filimu ya PA/PE, mutha kugwiritsanso ntchito zokutira za K.Zogulitsa zotentha kwambiri zitha kugwiritsidwa ntchito matumba a PVDC kapena matumba owuma.
Oyenera vacuum ma CD makhalidwe a chilichonse.
1. PE ndiyoyenera kugwiritsa ntchito kutentha pang'ono, RCPP ndiyoyenera kugwiritsa ntchito kutentha kwapamwamba kwambiri.
2. PA ndikuwonjezera mphamvu zakuthupi, ndi kukana puncture.
3. AL aluminiyamu zojambulazo akhoza kuonjezera chotchinga ntchito ndi mthunzi kuwala.
4. PET ikhoza kuonjezera mphamvu zamakina ndi kuuma kwabwino.
