Matumba otenthetsera kutentha kwambirindimatumba otenthazonse zimapangidwa ndi zinthu zophatikizika, zonse ndi zamatumba ophatikizira ophatikizikaZipangizo zodziwika bwino zophikira matumba ndi monga NY/CPE, NY/CPP, PET/CPE, PET/CPP, PET/PET/CPP, ndi zina zotero. Zipangizo zomwe zimagwiritsidwa ntchito kwambirikulongedza ndi kuphikazikuphatikizapo NY/CPP, PET/CPP, NY/NY/CPP, PET/PET/CPP, PET/AL/CPP, PET/AL/NY/CPP, ndi zina zotero.
Kapangidwe ka thumba lophikira ndi nthunzi kali ndi filimu yakunja ya polyester yolimbikitsira; Gawo lapakati limapangidwa ndi zojambulazo za aluminiyamu, zomwe zimagwiritsidwa ntchito popewa kuwala, chinyezi, ndi mpweya wotuluka; Gawo lamkati limapangidwa ndi filimu ya polyolefin (mongafilimu ya polypropylene), amagwiritsidwa ntchito potseka kutentha ndi kukhudzana ndi chakudya.
Matumba ophikira nthunzi amagwiritsidwa ntchito popakira zakudya, kotero chitetezo ndi kuyera kwa matumba apulasitiki nthawi zambiri zimakhala zapamwamba kwambiri popanga, ndipo sizingaipitsidwe ndi mabakiteriya osiyanasiyana. Komabe, sizingatheke popanga nthunzi yeniyeni, kotero kuyeretsa matumba ophikira nthunzi ndikofunikira kwambiri.Kuyeretsa matumba otenthetsera nthunziakhoza kugawidwa m'magulu atatu,
Pali njira zitatu zophikira matumba, zomwe ndi kuyeretsa thupi lonse, kuyeretsa thupi kutentha kwambiri, ndi kuyeretsa thupi kutentha kwambiri.
Kuyeretsa thupi lonse, kutentha kwa nthunzi pakati pa 100-200 ℃, kuyeretsa thupi kwa mphindi 30;
Mtundu woyamba: kutentha kwambiri, kutentha kwa nthunzi pa madigiri 121 Celsius, kuyeretsa kwa mphindi 45;
Mtundu wachiwiri: wopirira kutentha kwambiri, wokhala ndi kutentha kwa madigiri 135 Celsius ndi nthawi yoti ukhale wofewa kwa mphindi khumi ndi zisanu. Woyenera soseji, mpunga wachikhalidwe waku China ndi zakudya zina. Mtundu wachitatu: Matumba ophikira nthunzi ali ndi mawonekedwe oletsa chinyezi, kuteteza kuwala, kukana kutentha, komanso kusunga fungo labwino, ndipo ndi oyenera kugwiritsidwa ntchito muzakudya zophikidwa monga nyama, nyama yankhumba, ndi zina zotero.
Matumba otentha a madzindi mtundu wina wa thumba la pulasitiki lomwe ndi lamatumba otayira mpweya, makamaka yopangidwa ndi PA+PET+PE, kapena PET+PA+AL. Chikhalidwe cha matumba otentha m'madzi ndichakuti amalandira chithandizo cha anti-virus pa kutentha kosapitirira 110 ℃, ndi kukana mafuta bwino, kutseka kutentha kwambiri, komanso kukana kukhudza kwambiri.
Matumba owiritsa m'madzi nthawi zambiri amathiridwa madzi owiritsa, ndipo pali njira ziwiri zothirira madzi owiritsa,
Njira yoyamba ndi kuyeretsa thupi pogwiritsa ntchito kutentha kochepa, komwe kumatenga theka la ola kutentha kwa 100 ℃.
Njira yachiwiri: Kuyeretsa basi, kuyeretsa mosalekeza kwa theka la ola kutentha kwa 85 ℃
Mwachidule, njira yophera tizilombo toyambitsa matenda pogwiritsa ntchito matumba amadzi owiritsa ndikugwiritsa ntchito mphamvu yolimbana ndi kutentha kwa mabakiteriya ndikuwapatsa kutentha koyenera kapena nthawi yokwanira yotetezera kuti aphedwe kwathunthu.
Kuchokera ku njira zoyeretsera zomwe zili pamwambapa, zikuwoneka kuti pali kusiyana kwakukulu pakati pa matumba owiritsa ndi matumba otenthetsera. Kusiyana koonekeratu ndikuti kutentha kwa matumba otenthetsera nthawi zambiri kumakhala kokwera kuposa kwa matumba owiritsa.
