Kodi mwawona makona atatu pansi pa chidebe chapulasitiki?Kodi manambala osiyanasiyana mu makona atatu amaimira chiyani?LGLPAK.LTD idzakutengerani kuti mumvetsetse zomwe manambala akuyimira.
Pali manambala a 1-7 mu makona atatu pansi pa chidebe cha pulasitiki, chomwe chimayimira zipangizo zosiyanasiyana zapulasitiki, ndipo zizindikiro za pulasitiki izi ndizofunikira kwambiri pachitetezo chake.
1-PET PET botolo
Amapangidwa ndi polyethylene terephthalate, yomwe ilibe poizoni, imakhala ndi mpweya wabwino, ndipo sichimatulutsa flocs.Pambuyo pa kubadwanso, imakhala chinthu chachiwiri ndi phindu lachuma, chifukwa kugwiritsidwa ntchito kwake kukukulirakulira., Zida zachiwiri zimaperekedwa kunyumba ndi kunja, komanso zimatumizidwa ku China, zomwe zingagwiritsidwe ntchito ngati ulusi wosalukidwa, zippers, zodzaza, ndi zina zotero.
2-HDPE high density polyethylene
ufa woyera kapena granular mankhwala, sanali poizoni ndi zoipa, crystallinity ndi 80% ~90%, softening mfundo ndi 125℃ 35 ℃, kutentha utumiki akhoza kufika 100 ℃, mphamvu ndi kawiri kuposa otsika osalimba polyethylene, pulasitiki chikwama Common zipangizo.
3-PVC polyvinyl chloride
Pakali pano ndi pulasitiki yachiwiri yaikulu padziko lonse pambuyo pa polyethylene.Ili ndi mawonekedwe aamorphous a ufa woyera, ndi digiri yaing'ono ya nthambi, kachulukidwe kakang'ono pafupifupi 1.4, kutentha kwa galasi la 77 ~ 90 ° C, ndi kuwonongeka pafupifupi 170 ° C.Ili ndi kusakhazikika kwamafuta ndipo imawola kupanga hydrogen chloride pa kutentha kopitilira 100 ° C kapena padzuwa kwa nthawi yayitali.
4-LDPE otsika osalimba polyethylene
Ndiwo mitundu yomwe imagwiritsidwa ntchito kwambiri m'makampani opanga mapulasitiki ndi kusindikiza m'maiko osiyanasiyana.Amagwiritsidwa ntchito mu filimu ya tubular ndi njira yopangira kuwombera ndipo ndi yoyenera kuyika chakudya, kusungirako mankhwala tsiku ndi tsiku, fiber product phukusi, ndi zina zotero. Zinthuzo sizikulimbana ndi kutentha ndipo zidzasungunuka pamene kutentha kumapitirira 110 ° C.Ngati chakudyacho chitakulungidwa mu pulasitiki ndikutenthedwa, chimasungunula zinthu zovulaza.
5-PP polypropylene
Mphamvu zake zamakina, mphamvu zopindika, kachulukidwe ka mpweya, ndi chotchinga cha chinyezi ndizabwino kuposa filimu wamba yapulasitiki.Chifukwa filimu yapulasitiki iyi imakhala yowonekera bwino kwambiri, mtundu wopangidwanso pambuyo posindikiza ndi wowala kwambiri komanso wokongola, ndipo ndi chinthu chofunikira pakuyika kwa pulasitiki kosinthika.Imagonjetsedwa ndi dzimbiri ndi ma acid, alkalis, salt solutions ndi mitundu yosiyanasiyana ya zosungunulira zamoyo pansi pa 80 ℃, ndipo imatha kuwola pansi pa kutentha kwambiri ndi okosijeni.
6-PS polystyrene
Zomwe zimagwiritsidwa ntchito popanga mabokosi a noodles madzulo ndi mabokosi a chakudya chofulumira zimakhala ndi kutentha kwabwino, koma sizingayikidwe mu uvuni wa microwave.Kutentha kwakukulu kumatulutsa mankhwala oopsa.Ma asidi amphamvu ndi ma alkalis amathanso kuwola polystyrene yomwe imakhala yovulaza thupi la munthu.Samalani mukamagwiritsa ntchito.
7-PC polycarbonate ndi ena
PC ndi zinthu zomwe zimagwiritsidwa ntchito kwambiri, zomwe zimagwiritsidwa ntchito kwambiri popanga mabotolo a ana, makapu am'mlengalenga, ndi zina zotero. Zimatsutsana chifukwa cha kukhalapo kwa bisphenol A. Kutentha kwapamwamba, kumatulutsidwa, komanso mofulumira.Choncho, musagwiritse ntchito botolo la PC kuti mugwire madzi otentha ndipo musawawonetsere kuwala kwa dzuwa.
Ndikuganiza kuti aliyense akumvetsa kale tanthauzo la manambala.Mukhoza kusamala kwambiri pa moyo wanu ndikuyesera kupewa zinthu zomwe zingawononge thupi lanu.LGLPAK.LTD idzakutengerani kuti mumvetsetse zamakampani apulasitiki kuchokera kuukadaulo wamaluso.
