Gupakira ibikoresho byo kugura ibikoresho | Nigute ushobora guhitamo ibicuruzwa byiza bya pulasitiki

Guhitamo hamwe nubwiza bwibikoresho nurufunguzo rwo kwemeza ubwiza bwamazu, bizagira ingaruka kuburyo butaziguye no gutunganya amaherezo ya hose. Ibikoresho bya shitingi birimo polyethylene (kumubiri wumubiri no mumutwe), polypropilene (igifuniko cya tube), masterbatch, barin resin, gucapa wino, varish, nibindi. Kubwibyo rero, guhitamo ibikoresho byose bizagira ingaruka kumiterere ya hose. Nyamara, guhitamo ibikoresho biterwa nimpamvu nkibisabwa by isuku, imiterere ya barrière (ibisabwa kuri ogisijeni, umwuka wamazi, kubika impumuro nziza, nibindi), hamwe no kurwanya imiti.

Guhitamo imiyoboro: Icya mbere, ibikoresho byakoreshejwe bigomba kuba byujuje ubuziranenge bw’isuku, kandi ibintu byangiza nkibyuma biremereye hamwe n’ibikoresho bya fluorescent bigomba kugenzurwa mugihe cyagenwe. Kurugero, kumasuka yoherejwe muri Amerika, polyethylene (PE) na polypropilene (PP) yakoreshejwe igomba kuba yujuje ubuziranenge muri Amerika bushinzwe ibiryo n'ibiyobyabwenge (FDA) 21CFR117.1520.

Inzitizi yibikoresho: Niba ibikubiye mubipfunyika byamasosiyete ikora imiti ya buri munsi nibicuruzwa bimwe na bimwe byumva cyane ogisijeni (nka cosmetike yera) cyangwa impumuro nziza ihindagurika cyane (nkamavuta yingenzi cyangwa amavuta amwe, aside, umunyu na indi miti yangirika), ibice bitanu bifatanyirijwe hamwe bigomba gukoreshwa muriki gihe. Kuberako umwuka wa ogisijeni wa tariyeri eshanu zifatanije (polyethylene / adhesive resin / EVOH / adhesive resin / polyethylene) ni 0.2-1.2, mugihe umwuka wa ogisijeni wa polyethylene usanzwe ufite umurongo umwe ni 150-300. Mu gihe runaka, igipimo cyo kugabanya ibiro byumuyoboro wavanze urimo Ethanol wikubye inshuro icumi ugereranije n’umuyoboro umwe. Mubyongeyeho, EVOH ni Ethylene-vinyl alcool copolymer ifite inzitizi nziza kandi ikagumana impumuro nziza (ubunini bwa microne 15-20 nibyiza cyane).

Gukomera kw'ibikoresho: Isosiyete ikora imiti ya buri munsi ifite ibisabwa bitandukanye kugirango ikomere ya hose, none nigute ushobora kubona ubukana bwifuzwa? Polyethylene ikunze gukoreshwa mu mazu ni cyane cyane polyethylene nkeya, polyethylene yuzuye cyane, hamwe na polyethylene ifite umurongo muto. Muri byo, gukomera kwa polyethylene yuzuye cyane ni byiza kuruta ibya polyethylene nkeya, bityo rero ibyifuzo byifuzwa birashobora kugerwaho muguhindura igipimo cya polyethylene yuzuye cyane / polyethylene.

Kurwanya imiti yibikoresho: polyethylene yuzuye cyane ifite imiti irwanya imiti kuruta polyethylene nkeya.

Kurwanya ikirere cyibikoresho: Kugenzura imikorere yigihe gito cyangwa kirekire cyigihe cya hose, ibintu nkibigaragara, kurwanya umuvuduko / kurwanya ibitonyanga, imbaraga zo gufunga, kurwanya ibidukikije byangiza ibidukikije (agaciro ka ESCR), impumuro nziza no gutakaza ibikoresho bikora bikenewe gusuzumwa.

Guhitamo igishushanyo mbonera: Masterbatch igira uruhare runini mugucunga ubuziranenge bwa hose. Kubwibyo, mugihe uhitamo masterbatch, isosiyete ikoresha igomba gusuzuma niba ifite itandukaniro ryiza, kuyungurura hamwe nubushyuhe bwumuriro, kurwanya ikirere no kurwanya ibicuruzwa. Muri byo, ibicuruzwa birwanya masterbatch ni ngombwa cyane mugihe cyo gukoresha hose. Niba igishushanyo mbonera kidahuye nibicuruzwa, ibara rya masterbatch rizimukira kubicuruzwa, kandi ingaruka zirakomeye cyane. Kubwibyo, buri munsi uruganda rukora imiti rugomba gusuzuma ihame ryibicuruzwa bishya hamwe na hose (ibizamini byihuse mubihe byagenwe).

Ubwoko bwa varish nibiranga: Varnish ikoreshwa muri hose igabanijwemo ubwoko bwa UV nubwoko bwumisha, kandi birashobora kugabanywa hejuru yumucyo no hejuru ya matte muburyo bwo kugaragara. Varnish ntabwo itanga gusa ingaruka nziza ziboneka, ahubwo inarinda ibirimo kandi igira ingaruka runaka zo guhagarika ogisijeni, imyuka y'amazi n'impumuro nziza. Muri rusange, varnish yumisha ubushyuhe ifata neza mugushiraho kashe ishyushye hamwe no gucapisha silik-ecran, mugihe UV varish ifite ububengerane bwiza. Isosiyete ikora imiti ya buri munsi irashobora guhitamo langi ikwiranye nibiranga ibicuruzwa byabo. Byongeye kandi, langi yakize igomba kuba ifatanye neza, hejuru yubusa itarinze gutobora, irwanya igabanuka, irwanya kwambara, irwanya ruswa, kandi nta ibara rihinduka mugihe cyo kubika.

Ibisabwa kumubiri wigituba / umutwe wumutwe: 1. Ubuso bwumubiri wigituba bugomba kuba bworoshye, butagira imirongo, ibishushanyo, imirongo, cyangwa kugabanuka. Umubiri wigituba ugomba kuba ugororotse kandi ntunamye. Uburebure bw'urukuta rw'igituba bugomba kuba bumwe. Uburebure bwurukuta rwumuyoboro, uburebure bwigituba, hamwe no kwihanganira diameter bigomba kuba mubipimo byagenwe;

2. Umutwe wigitereko numubiri wa hose bigomba guhuzwa neza, umurongo uhuza ugomba kuba mwiza kandi mwiza, kandi ubugari bugomba kuba bumwe. Umutwe wigituba ntugomba guhindagurika nyuma yo guhuza; 3. Umutwe wigituba nigifuniko cyigituba bigomba guhuza neza, byinjira kandi bigasohoka neza, kandi ntihakagombye kunyerera murwego rwagenwe, kandi ntihakagombye kubaho amazi cyangwa umwuka uva hagati yigituba nigifuniko;

Ibisabwa byo gucapa: Gutunganya Hose mubisanzwe bikoresha icapiro rya lithographie ya offset (OFFSET), kandi ibyinshi muri wino ikoreshwa ni UV-yumye, mubisanzwe bisaba gufatana runini no kurwanya ibara. Ibara ryo gucapa rigomba kuba muburebure bwimbitse, umwanya wanditseho ugomba kuba wuzuye, gutandukana bigomba kuba muri 0.2mm, kandi imyandikire igomba kuba yuzuye kandi isobanutse.

Ibisabwa kumapeti ya pulasitike: Ububiko bwa plastike mubusanzwe bukozwe muburyo bwa polypropilene (PP). Ibipapuro bya pulasitiki byujuje ubuziranenge ntibigomba kugira imirongo igaragara yo kugabanuka no kumurika, imirongo ibumba neza, ibipimo nyabyo, kandi bihuye neza n'umutwe w'igituba. Ntibagomba guteza ibyangiritse nkibice byacitse cyangwa ibice mugihe gikoreshwa bisanzwe. Kurugero, mugihe imbaraga zo gufungura ziri murwego, flip cap igomba kuba ishobora kwihanganira inshuro zirenga 300 zitavunitse.
