Multi-layer blow blowingwakha udonga lwesikhongozeli ukusuka kumaleko eplastiki amabini okanye ngaphezulu, ngalinye lisenza umsebenzi owahlukileyo - umaleko wesithintelo ukuvala ioksijini okanye umphunga wamafutha, undoqo ohlaziyiweyo ukucutha iindleko, izikhumba ezinyulu kwindawo ecocekileyo. Zidityaniswe kunye ngentloko enye yokufa, ukuze udonga luphume lungenamthungo kwaye ludityanisiwe. Uyayidinga xa imathiriyeli enye ingakwazi ukwenza yonke into: itanki yamafutha ekungafuneki ivuze umphunga, ibhotile yejusi ekufuneka igcine ioksijini ngaphandle konyaka, isikhongozeli ekufuneka sibethe iithagethi zomxholo ohlaziyiweyo ngaphandle kokungcolisa into engaphakathi. Oomatshini be-KGH be-curved-arm be-KGH baqhuba i-1 ukuya kwi-6 umaleko kwizikhongozeli ukusuka kwi-5 ukuya kwi-30 yeelitha.
Uninzi lweebhotile zeplastiki ziyinto enye, udonga olunye, lwenziwe. Cofa i-HDPE ngokufa, yivuthele, yikhuphe. Ilula, itshiphu, kwaye ilungile kuninzi lwezikhongozeli. Kodwa ezinye iimveliso zicela into enye iplastiki engenako ukunika. Kwaye kulapho i-multi-layer ingena khona.
Sifumana iqhinga elizingileyo labathengi abaxelelwe ukuba bafuna "i-co-extrusion" okanye "umatshini onemigangatho emithandathu" kwaye abaqinisekanga ukuba bathengwa ngantoni - okanye bayathengiswa na. Ke nantsi inguqulelo ecacileyo: into eyenziwa ngamaleko, xa iyifanele, kwaye xa ungcono ngokuhlala umaleko omnye.
Lithetha ukuthini igama elithi "multi-layer" kumgangatho wefektri
Single-umaleko enye extruder ukondla intloko die enye impahla enye. I-Multi-layer yi-extruders eliqela - nganye inyibilikisa i-resin eyahlukileyo kwiqondo lobushushu bayo - yonke isondla enye ekwabelwana ngayo.co-extrusion die intloko. Ngaphakathi kwaloo ntloko, imijelo enyibilikayo eyahlukileyo ibotshelelwa kwiileya ezixineneyo, ngoko ke icawa iyawa sele yolekiwe. Emva koko ivuthela kanye njengayo nayiphi na enye icawa.
Yicinge njengeplywood, ngaphandle kokuba iileya zenziwe kwaye zixutywe ngokudubula okukodwa kunokuba zincamathelwe njengamashiti. Kwaye amagama amabini oya kuva - "i-multi-layer" kunye ne "co-extrusion" - ichaza into efanayo ukusuka kwiziphelo ezahlukeneyo. I-Co-extrusion yindlela; Umaleko oluninzi sisiphumo.
Ubalo lomaleko ludla ngokuhlala ku-2, 3, 5, okanye 6, kwaye inani ngalinye linesizathu emva kwalo. Siza kufika kuloo nto. Okokuqala, iileya ngokwazo.
Ukuba umaleko ngamnye ukwenzelwa ntoni
Umaleko wesithintelo - isizathu sokuba uninzi lwemisebenzi yamaleko amaninzi ikhona
I-HDPE engenanto kunye ne-PET zilungile kwizinto ezininzi, kodwa zihamba kancinci kwiigesi ngokuhamba kwexesha. Kwiimveliso ezininzi, ngubani okhathalayo. Kwabanye, ngumdlalo webhola wonke. Ioksijini erhubuluzayo imosha ukutya. Umphunga wamafutha orhubuluza etankini wophula imithetho ekhutshwayo kwaye yingxaki yokhuseleko. Isinyibilikisi esinamandla sisebenza kancinane eludongeni esingasithandiyo.
Yiloo nto umaleko womqobo olungisayo.EVOH(i-ethylene vinyl alcohol) ngumgangatho wegolide wokuthintela ioksijini kunye neehydrocarbons;PA(inayiloni) lolunye ukhetho oluqhelekileyo. Nantsi into yokubambisa ekhwelisa abantu: I-EVOH iyabiza, kwaye iyabucaphukela ukufuma - ukufuma kuyonakalisa ukusebenza kwayo komqobo. Ngoko awuze uyibeke phezu komhlaba. Uyingcwaba embindini, i-sliver ye-millimeter ubukhulu, ikhuselwe macala omabini. I-core EVOH encinci yenza i-blocking; HDPE cheap yenza isambuku eludongeni. Umaleko omncinci, umphumo omkhulu.
Umaleko osetyenzisiweyo/ogaywe ngokutsha — iindleko kunye nePPWR
Wonke umgca wokubumba uvelisa i-trim - inkunkuma ye-pinch-off phezulu kunye nomsila wecandelo ngalinye. Yigaye kwaye unemathiriyeli elunge ngokugqibeleleyo, hayi nje izinto ozifunayo ukubamba imveliso okanye ubonise ngaphandle. Ngoko uyondla kwakhona njengomaleko ophakathi wangcwatywa. Igalelo lasimahla, akukho kuthomalalisa kumphezulu obalulekileyo.
Iqhinga elifanayo liphatha umxholo ohlaziyiweyo wasemva komthengi. ISandwich PCR resin embindini, gcina iplastiki yebakala lokutya okunyulu kwizikhumba zangaphakathi nezingaphandle, kwaye ungabetha iithagethi zomxholo osetyenzisiweyo-kuquka imida ye-EU esiyigubungeleyo kwiqhekeza lethu lokuthobela iPPWR - ngaphandle kwezinto ezisetyenzisiweyo ukuba ziqhagamshelane nento engaphakathi ebhotileni. Kwiimpawu ezininzi ezileqa izigunyaziso ze-PCR ezingama-2030, uluhlu oluninzi yeyona ndlela icocekileyo ekhoyo.
Tie umaleko - abo wonke umntu uyalibala
Ngoku inxalenye ebamba abathengi xa bexabisa umsebenzi. I-EVOH kunye nenayiloni ayidibanisi ne-polyethylene. Zibeke ecaleni kwaye ziya kudiliza - iileya ziyahlukana njenge-laminate engahambanga kakuhle, kwaye inxalenye yonakalisiwe.
Ngoko ke phakathi kwepere nganye yezinto ezingayi kuncamathela, udinga itie umaleko: intlaka encamathelayo ebhityileyo ethi ibambe macala omabini. Kungenxa yoko le nto itanki yamafutha "i-6-layer" iyi-HDPE yangaphandle ngokwenene, i-regrind, iqhina, umqobo, iqhina, i-HDPE yangaphakathi. Iimaleko zokubopha zizileya nazo. Zishiye ngaphandle kwesicwangciso sakho kwaye mhlawumbi unenxalenye ewayo okanye isibalo somaleko esingadibanisiyo. Azikhethi, kwaye ziyinto yomgca wokwenyani.
Apho uluhlu oluninzi lufumana iindleko zalo
Iitanki zamafutha emoto (imigangatho emithandathu yakudala)
Le yimeko yeencwadi. Itanki yamafutha eplastiki ayinakuvumela umphunga wehydrocarbon ukuba ugqobhoze eludongeni lwayo - imigaqo yokukhupha ayikuvumeli oko, kwaye ngumba wokhuseleko. Ukwakhiwa okusemgangathweni yisakhiwo se-HDPE, i-regrind layer, i-tie layer, isithintelo se-EVOH, enye i-tie layer, kunye ne-HDPE yangaphakathi. Imigangatho emithandathu, kunye ne-EVOH yenza i-permeation blocking kunye ne-tie layers ebambe isandwich kunye. Kinggle ikhathalogu uluhlu amatanki amafutha phantsi iinxalenye auto, kunye neitanki kanye uhlobo enzima, ngenkani inxalenye egobileyo-ingalo oomatshini multi- umaleko zakhiwe ukwenza.
Ukutya, isiselo kunye nokupakishwa kwezithambiso
I-ketchup, i-sauce, okanye ibhotile yejusi ekufuneka ihlale kwi-shelf unyaka wonke idinga umqobo we-oxygen, okanye iziqulatho ze-oxidise kunye ne-spoil. Udonga olunemigangatho emithathu (intombi enyulu / umqobo / intombi enyulu) okanye ulwakhiwo olupheleleyo olunesihlanu luyayibamba loo nto. Izithambiso zifikelela kwi-multi-layer ngesizathu esahlukileyo kakhulu - isikhumba sangaphandle esinombala okanye se-pearlescent ngaphezulu komgangatho wangaphakathi owahlukileyo, okanye "umgca wokujonga" ocacileyo okhutshwe ngokudibeneyo phantsi kwecala lebhotile ye-opaque ukuze umsebenzisi abone ukuba ingakanani imveliso eseleyo. Lo mgca kwibhotile yakho yesicoci? Co-extruded.
Izikhongozeli zeAgrochemical kunye nezemichiza yasekhaya
Isibulali-zinambuzane esinobundlongondlongo okanye isinyibilikisi sinokungena okanye sicinezele udonga olucacileyo lweHDPE kwiinyanga zokugcina. Umqobo okanye umaleko we-fluorinated uthenga ukuchasana kweekhemikhali kunye nobomi beshelufu, yiyo loo nto uninzi lwepakethe ye-agrochemical i-multi-layer kunokuba ibe nye.
