Firimu repurasitiki sechinhu chekudhinda, rinodhindwa sebhegi rekurongedza, rine chiedza uye chakajeka, kunyorova uye kushorwa kweokisijeni, kusimba kwemhepo yakanaka, kuoma uye kupeta kuramba, nzvimbo yakatsetseka, inogona kuchengetedza chigadzirwa, uye inogona kubereka chimiro che chigadzirwa, ruvara uye zvimwe zvakanakira.Nekuvandudzwa kweindasitiri yepetrochemical, akawanda uye akawanda marudzi epurasitiki firimu, anowanzo shandiswa epurasitiki firimu polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PS), polyester firimu (PET), polypropylene (PP), naironi (PA) zvichingoenda zvakadaro.Pamusoro pezvo, kune mamwe marudzi mazhinji emafirimu epurasitiki, nyanzvi inochinjika yekurongedza mugadziri Shunfa kurongedza anofunga kuti zvinodikanwa kuti unzwisise hunhu hwefirimu repurasitiki pamberi pemabhegi ekurongedza.Yakanyatso kurongeka hunhu hwemhando gumi nembiri dzefirimu repurasitiki pasi pebhegi rekurongedza kuti utarise.
1. Polyvinyl chloride (PVC)
Zvakanakira zvePVC firimu uye PET zvakafanana, uye zvakafanana ndezvehunhu hwekujeka, kufema, asidhi uye alkali kuramba.Mabhegi mazhinji ekutanga ezvekudya anogadzirwa nemabhegi ePVC.Zvisinei, PVC inogona kusunungura carcinogens nekuda kwekusakwana kwepolymerization yevamwe monomers mukugadzirwa kwekugadzira, saka haina kukodzera kuzadza zvokudya-giredhi zvinhu, uye vakawanda vakachinja kuva PET packaging mabhegi, kutara chiratidzo chinhu Nha.
2. Polystyrene (PS)
Kutorwa kwemvura kwemufirimu wePS kwakadzikira, asi kugadzikana kwayo kuri nani, uye inogona kugadziriswa nekupfura kufa, kudzvanya kufa, extrusion uye thermoforming.Kazhinji, inopatsanurwa kuita zvikwata zviviri zvinopupuma furo zvichienderana nekuti yafamba sei mukupupa.Unfoamed PS inonyanya kushandiswa mukuvaka, matoyi, stationery, zvichingodaro, uye inogona zvakare kugadzirwa kazhinji mumidziyo yakazara neyakaviriswa zvigadzirwa zvemukaka, nezvimwewo. iNhamba 6.
3. Polypropylene (PP)
Yakajairika PP firimu inotora kuvhuvhuta kuvhuvhuta, yakapusa maitiro uye yakaderera mutengo, asi iyo optical performance yakadzikira zvishoma pane CPP neBOPP.Chinhu chikuru chePP ndechekudzivirira kwekushisa kwepamusoro (inenge -20 ° C ~ 120 ° C), uye nzvimbo yekunyunguduka inosvika 167 ° C, iyo inokodzera kuzadza mukaka wesoya, mukaka wemupunga uye zvimwe zvigadzirwa zvinoda disinfection. .Kuoma kwayo kwakakwirira kudarika PE, iyo inoshandiswa kugadzira zvivharo zvemudziyo, uye chiratidzo chezvinyorwa ndeche 5. Kazhinji kutaura, PP ine kuoma kwepamusoro, uye iyo yepamusoro inonyanya kupenya, uye haibudisi kunhuhwirira kunopisa kana kupisa, nepo PE ine kunhuhwirira kwekenduru inorema.
4. Polyester Firimu (PET)
Polyester firimu (PET) ndeye thermoplastic engineering plastiki.Nyeredzi dzakatetepa dzakagadzirwa neshizha gobvu neextrusion nzira uye bidirectional kutambanudza.Firimu rePolyester rinoratidzirwa neakanakisa emuchina zvivakwa, kusimba kwepamusoro, kuomarara uye kuoma, kushomeka kwepuncture, friction resistance, yakakwirira uye yakaderera tembiricha kuramba, makemikari kuramba, mafuta kuramba, kusimba kwemhepo uye kuchengetedza kunhuhwirira kwakanaka, ndeimwe yeanowanzo shandiswa permeability resistance composite. firimu substrates, asi corona kuramba haina kunaka, mutengo wakakwira.Ukobvu hwefirimu hunowanzo 0.12mm, iyo inowanzoshandiswa sechinhu chekunze chebhegi rekurongedza chikafu, uye kudhindwa kwakanaka.Maka chiratidzo chechinhu 1 muchigadzirwa chepurasitiki.
5. Nylon (PA)
Nylon plastiki firimu (polyamide PA) parizvino iri kugadzirwa kwemaindasitiri emhando dzakawanda, idzo mhando huru dzinoshandiswa kugadzira firimu dzinoti nylon 6, naironi 12, nylon 66 zvichingodaro.Firimu renaironi ifirimu rakaoma kwazvo, kujeka kwakanaka, uye rine kupenya kwakanaka.Kusimba kwesimba, kusimba kwesimba, yakakwirira uye yakaderera tembiricha kuramba, mafuta kuramba, organic solvent kuramba, kupfeka kuramba uye puncture kuramba kwakanaka kwazvo, uye firimu iri rakapfava, rakanakisa reokisijeni kuramba, asi iyo mhute yemvura inovharira haina kunaka, kunyura munyoro, mwando permeability yakakura, uye kupisa kuvharika kwakashata.Inokodzera kurongedza zvinhu zvakaoma, senge chikafu chine mafuta, chikafu chakakangwa, vacuum yekurongedza chikafu, kubika chikafu, nezvimwe.
6. High Density Polyethylene (HDPE)
Firimu reHDPE rinonzi geomembrane kana firimu risingapindiki.Iyo yekunyungudika kwayo ndeye 110 ℃-130 ℃, uye hukama hwayo huri 0.918-0.965kg/cm3.Iyo yakakwira crystallinity, isiri-polar thermoplastic resin, iyo yekutanga HDPE kutaridzika ichena mukaka, mudiki muchinjiko-chikamu cheimwe dhigirii yekupenya.Iine kumira zvakanaka kune yakakwirira uye yakaderera tembiricha uye kukanganisa kupikisa, kunyangwe pa -40F yakaderera tembiricha.Kugadzikana kwayo kwemakemikari, kusimba, kusimba, simba remagetsi, simba rekubvarura zvinhu zvakanakisa, uye nekuwedzera kwe density, mechanical properties, barriers properties, tensile simba uye kupisa kupisa kunovandudzwa zvakakodzera, inogona kuramba acid, alkali, organic solvents nezvimwe. ngura.Kuzivikanwa: kazhinji kupenya, inonzwa kunge wakisi, bhegi repurasitiki rinokwesha kana kukwesha kana uchiita ruzha.
7. Low Density Polyethylene (LDPE)
LDPE firimu density yakaderera, yakapfava, yakaderera tembiricha kuramba, kukanganisa kuramba kemikari kugadzikana kwakanaka, mumamiriro ezvinhu akajairwa acid (kunze kweiyo yakasimba oxidizing acid), alkali, munyu corrosion, ine magetsi ekudzivirira.LDPE inonyanya kushandiswa mumabhegi epurasitiki, kuisa chiratidzo chezvinyorwa ndeyeNo.Kuzivikanwa: Bhegi repurasitiki rakagadzirwa neLDPE rakapfava, risinganyanye kuita ruzha kana uchikanya, firimu repurasitiki rekurongedza rekunze rakapfava uye riri nyore kubvarura LDPE, uye yakanyanya brittle uye yakaoma iPVC kana PP firimu.
8. Polyvinyl Doro (PVA)
Polyvinyl doro (PVA) yakakwira barriers composite firimu ifirimu rine yakakwirira chipingamupinyi chivakwa chakagadzirwa nekuputira yakagadziridzwa mvura-inonyungudika mvura yepolyvinyl doro pane substrate yepolyethylene plastiki.Nekuti iyo yakakwira chipingamupinyi chinosanganiswa firimu repolyvinyl doro rine zvakanaka zvipingamupinyi zvivakwa uye rinosangana nezvinodiwa zvekuchengetedzwa kwezvakatipoteredza, tarisiro yemusika weiyi yekurongedza zvinhu inopenya kwazvo, uye kune yakafara nzvimbo yemusika muindasitiri yechikafu.
9. Kukandira polypropylene Firimu (CPP)
Casting polypropylene firimu (CPP) imhando yeisinga tambanuke, isina-yakatarisana flat extrusion firimu inogadzirwa nekunyunguduka kukandira kudzima kutonhora.Iyo inoratidzirwa nekukasira kugadzira kukurumidza, goho rakawanda, kujeka kwefirimu, kupenya, chipingamupinyi pfuma, kupfava, ukobvu kufanana kwakanaka, inogona kutsungirira kupisa kwekushisa kwepamusoro (kubikira tembiricha iri pamusoro pe120 ° C) uye yakadzika tembiricha yekupisa chisimbiso (tembiricha yekuisa chisimbiso isingasviki. 125 ° C), chiyero chekuita chakanakisa.Basa rekutevera rakadai sekudhinda, composite iri nyore, inoshandiswa zvakanyanya mumachira, chikafu, kurongedza zvinodiwa zvezuva nezuva, ita iyo yemukati substrate yekuputira inoumbwa, inogona kuwedzera hupenyu hwesherufu yechikafu, kuwedzera runako.
10. Bidirectional polypropylene film (BOPP)
Biaxial polypropylene firimu (BOPP) chinhu chakajeka chinochinjika chekurongedza bhegi chakagadzirwa mu1960s, inova yakakosha mutsara wekugadzira kusanganisa polypropylene mbishi zvinhu uye zvinoshanda zvekuwedzera, kunyunguduka nekusanganisa, kugadzira mapepa, uyezve kugadzira firimu nekutambanudza.Iyi firimu haina chete zvakanakira yeakaderera density, corrosion resistance uye yakanaka kupisa kupisa kweyakatanga PP resin, asiwo ine yakanaka optical properties, high mechanical simba, rakapfuma raw material sources, yakanakisa kudhinda zvinhu, uye inogona kusanganiswa nebepa, PET uye mamwe ma substrates.Iine tsananguro yakakwira uye gloss, yakanakisa inki kunyura uye kunamatira kunamatira, simba rakakwirira rekusimba, yakanakisa mafuta inodzivirira zvivakwa, yakaderera electrostatic maitiro.
11. Firimu yesimbi
Metalized film ine hunhu hweese epurasitiki firimu nesimbi.Basa realuminium plating pamusoro pefirimu ndeyekuvhara chiedza uye kudzivirira ultraviolet mwaranzi, iyo inowedzera hupenyu hwesherufu yezviri mukati uye inovandudza kupenya kwefirimu, kutsiva iyo aluminium foil kune imwe nhanho, uye zvakare ine yakachipa, yakanaka uye yakanaka chipingamupinyi zvinhu.Naizvozvo, bhaisikopo resimbi rinoshandiswa zvakanyanya mukubatanidza kurongedza, rinonyanya kushandiswa mumabhisikiti uye mamwe akaoma, akaputirwa chikafu chekurongedza, mushonga uye zvizorwa kurongedza.
