Hose, iri nyore uye ine mari yekurongedza zvinhu, inoshandiswa zvakanyanya mumunda wemakemikari ezuva nezuva uye yakakurumbira. Hose yakanaka haigone kuchengetedza zviri mukati chete, asiwo inovandudza chiyero chechigadzirwa, nokudaro kuhwina vatengi vakawanda kumakambani emakemikari emazuva ese. Saka, kumakambani emakemikari ezuva nezuva, maitiro ekusarudzahose dzepurasitiki dzemhando yepamusoroizvo zvinokodzera zvigadzirwa zvavo?
Kusarudzwa uye hutano hwezvinhu ndicho chinhu chikuru chekuvimbisa hutano hwemahosi, izvo zvichakanganisa zvakananga kugadzirisa uye kushandiswa kwekupedzisira kwehosi. Zvinhu zvepurasitiki hoses zvinosanganisira polyethylene (yechubhu muviri uye tube musoro), polypropylene (tube chivharo), masterbatch, chipingamupinyi resin, kudhinda inki, varnish, etc. Naizvozvo, kusarudzwa kwechinhu chero chipi zvacho kuchakanganisa zvakananga kunaka kwepombi. Nekudaro, kusarudzwa kwezvinhu kunoenderanawo nezvinhu zvakaita sehutsanana zvinodiwa, zvipingamupinyi zvivakwa (zvinodiwa zveokisijeni, mhute yemvura, kuchengetedza kunhuhwirira, nezvimwewo), uye makemikari kuramba.
Kusarudzwa kwepombi: Chekutanga, zvinhu zvinoshandiswa zvinofanirwa kusangana nehutsanana hwakakodzera, uye zvinhu zvinokuvadza zvakaita sesimbi inorema uye fluorescent agents zvinofanirwa kudzorwa mukati meiyo yakatarwa. Semuyenzaniso, pamapombi anoendeswa kunze kwenyika kuUnited States, iyo polyethylene (PE) uye polypropylene (PP) inoshandiswa inofanira kusangana neUS Food and Drug Administration (FDA) chiyero 21CFR117.1520.
Zvipingamupinyi zvezvinhu zvemidziyo: Kana zviri mukati mekurongedzerwa kwemakambani emakemikari emazuva ese zviri zvimwe zvigadzirwa zvinonyanya kunzwa mweya weokisijeni (senge mamwe machena ekuzora) kana kunhuhwirira kwakanyanyisa (senge akakosha oiri kana mamwe mafuta, asidhi, munyu uye mamwe makemikari anoparadza), mashanu-layer co-extruded chubhu inofanira kushandiswa panguva ino. Nekuti iyo oxygen inopinza ye5-layer co-extruded chubhu (polyethylene/adhesive resin/EVOH/adhesive resin/polyethylene) 0.2-1.2 units, ukuwo oxygen permeability yeyakajairika polyethylene single-layer chubhu i150-300 units. Mune imwe nguva yenguva, chiyero chekurasikirwa kwehuremu hwechubhu ye-co-extruded ine ethanol yakadzikira kakapetwa kamakumi maviri pane iyo yechubhu imwe chete. Pamusoro pezvo, EVOH ndeye ethylene-vinyl doro copolymer ine yakanakisa chipingamupinyi zvivakwa uye kunhuhwirira kuchengetedza (yakanakisa mhedzisiro inowanikwa kana ukobvu huri 15-20 microns).
Kuoma kwezvinhu: Makambani emakemikari emazuva ese ane zvinodiwa zvakasiyana pakuomarara kwemahosi, saka ungawana sei kuomarara kwaunoda? Iyo polyethylene inowanzoshandiswa mumapombi inonyanya kudzika-density polyethylene, high-density polyethylene, uye linear low-density polyethylene. Pakati pavo, kuoma kwe-high-density polyethylene iri nani kudarika ye-low-density polyethylene, saka kuoma kunoda kunogona kuwanikwa nekugadzirisa chiyero chepamusoro-density polyethylene / pasi-density polyethylene.
Mushonga wemakemikari wezvinhu: High-density polyethylene ine nani makemikari kuramba pane yakaderera-density polyethylene.
Kupokana kwemamiriro ekunze emidziyo: Kudzora kushanda kwenguva pfupi kana kwenguva refu kwemahosi, zvinhu zvakaita sechitarisiko, kumanikidza kuramba / kudonha kuita, kusimba kwekuisa chisimbiso, kwezvakatipoteredza kusagadzikana kupaza kuramba (ESCR kukosha), kunhuhwirira uye kurasikirwa kwezvinhu zvinoshanda zvinoda kufungwa.
Kusarudzwa kwe masterbatch: Masterbatch inoita basa rakakosha mukutonga kwemhando yemahosi. Naizvozvo, pakusarudza masterbatch, makambani evashandisi anofanirwa kufunga kana ine yakanaka dispersibility, kusefa uye kugadzikana kwekupisa, kuramba kwemamiriro ekunze uye kuramba kwechigadzirwa. Pakati pavo, kupikisa kwechigadzirwa che masterbatch kunonyanya kukosha panguva yekushandiswa kwemahosi. Kana iyo masterbatch isingaenderani nechigadzirwa chairi, ruvara rwe masterbatch ruchatamira muchigadzirwa, uye mhedzisiro yacho yakanyanya. Naizvozvo, makambani emakemikari emazuva ese anofanirwa kuyedza kugadzikana kwezvigadzirwa zvitsva uye hoses (yakawedzera bvunzo pasi pemamiriro akatarwa).
Mhando dzevarnish uye hunhu hwadzo: Iyo varnish inoshandiswa kune hose yakakamurwa kuva UV mhando uye kupisa kuomesa mhando, iyo inogona kukamurwa kuva yakajeka pamusoro uye matte pamusoro pakuonekwa. Varnish haisi kungopa maitiro akanaka ekuona, asiwo inodzivirira zviri mukati uye ine imwe mhedzisiro yekuvhara oksijeni, mhute yemvura uye kunhuhwirira. Kazhinji kutaura, kupisa kuomesa mhando varnish ine yakanaka kunamatira kune inotevera inopisa kutsika uye sirika skrini kudhinda, nepo UV varnish iine gloss iri nani. Makambani emakemikari emazuva ese anogona kusarudza varnish yakakodzera zvinoenderana nehunhu hwezvigadzirwa zvavo. Uye zvakare, iyo varnish yakarapwa inofanirwa kuve nekunamira kwakanaka, yakatsetseka pasi isina gomba, kupeta kuramba, kupfeka kuramba, kusaita ngura, uye kusaita ruvara panguva yekuchengetedza.
Zvinodikanwa zvechubhu muviri / chubhu musoro:
1. Kumusoro kwemuviri wechubhu kunofanirwa kuve kwakatsetseka, pasina mitsetse, scratches, dhizaini, kana shrinkage deformation. Muviri wechubhu unofanirwa kuve wakatwasuka uye usingakotame. Iyo chubhu madziro ukobvu hunofanira kunge hwakafanana. Iyo chubhu madziro ukobvu, kureba kwechubhu, uye dhayamita kushivirira kunofanirwa kunge kuri mukati meiyo yakatarwa;
2. Musoro wechubhu uye muviri wechubhu wepombi unofanirwa kubatanidzwa zvakasimba, mutsara wekubatanidza unofanirwa kuva wakanaka uye wakanaka, uye hupamhi hunofanira kuva yunifomu. Musoro wechubhu haufanirwe kutsvetwa mushure mekubatana;
3. Musoro wechubhu uye chivharo chechubhu chinofanira kuenderana zvakanaka, kupinza mukati uye kunze zvakanaka, uye hapafanirwe kutsvedza mukati meiyo torque yakatarwa, uye hapafanirwe kuve nemvura kana kubuda kwemhepo pakati pechubhu nechivharo;
Kudhinda zvinodiwa: Hose processing inowanzoshandisa lithographic offset printing (OFFSET), uye yakawanda yeinki inoshandiswa ndeye UV-yakaomeswa, iyo inowanzoda kunamatira kwakasimba uye kuramba kushanduka. Rudzi rwekudhinda runofanira kunge rwuri mukati meiyo yakataurwa yakadzika renji, iyo overprint chinzvimbo inofanirwa kuve yakarurama, kutsauka kunofanira kunge kuri mukati me 0.2mm, uye font inofanira kunge yakazara uye yakajeka.
Zvinodiwa zvemapurasitiki caps: Zvivharo zvepurasitiki zvinowanzogadzirwa ne polypropylene (PP) jekiseni rekuumba. Mapepa epurasitiki emhando yepamusoro haafanire kunge asina mitsara inodzikira uye inopenya, mitsetse yakatsetseka mold, zviyero zvakaringana, uye yakatsetseka inoenderana nemusoro wechubhu. Izvo hazvifanirwe kukonzera kukanganisa kwechimiro senge brittle cracks kana kuputika panguva yekushandiswa kwakajairika. Semuenzaniso, kana simba rekuvhura riri mukati mechikamu, flip cap inofanira kukwanisa kupeta kupfuura mazana matatu pasina kutyora.
Ini ndinotenda kuti kutanga kubva pane zviri pamusoro, mazhinji emazuva ese emakemikari makambani anofanirwa kukwanisa kusarudza emhando yepamusoro hose kurongedza zvigadzirwa.
