Ⅰ Mhando dzemabhegi epurasitiki
Plastic bag i polymer synthetic material, kubvira payakagadzirwa, yave zvishoma nezvishoma chikamu chakakosha chehupenyu hwezuva nezuva hwevanhu nekuda kwekuita kwayo kwakanaka. Zvinodiwa nevanhu zuva nezuva, zvechikoro nezvebasa uye zvichingodaro zvese zvine mumvuri wepurasitiki. Kwete chete mune zvinodiwa zvezuva nezuva, mapurasitiki anoshandiswawo zvakanyanya mumaindasitiri akasiyana akadai sekurapa uye kuvaka. Kunyanya, mabhegi epurasitiki, ayo akareruka muhuremu, akakura muhukuru uye anogona kuchengeta zvinhu zvakasiyana-siyana, ave akakosha uye akakosha mubatsiri muhupenyu hwevanhu. Heano mamwe emhando dzakasiyana dzemabhegi akagadzirwa epurasitiki.
1.Vest bag
Nekuti chimiro chemamwe mabhegi epurasitiki uye hupenyu hwezuva nezuva hwevanhu vanopfeka hembe yemukati yakafanana, saka vanhu vanoidaidza kuti bhegi remukati, rinogona kunzi bhegi revheti. Iri rudzi rwebhegi rinowanzo shandisa chinhu chinonzi PO sechinhu chikuru chekugadzira. Nekuti maitiro ekugadzira bhegi revest ari nyore uye anoshanda zvakasiyana, anogona kushandiswa muzvitoro zvikuru, mashopu, zvitoro zviri nyore, misika yemisika nedzimwe nzvimbo, saka yakambove chimwe chezvinhu zvakakosha muhupenyu hwezuva nezuva hwevanhu. Nekudaro, nekuda kwedambudziko remabhegi emukati mabhegi zvigadzirwa, zvichikonzera kusvibiswa kwakakomba kwezvakatipoteredza, mushure mekumiswa kwekurambidzwa kwepurasitiki, nyika yakatanga kurambidza nekurambidza kugadzirwa nekugadzirwa kwebarbed akadaro.
2.Kutakura mabhegi
Iri bhegi rakasiyana nebhegi remukati, rakagadzirwa nechinhu chisina chepfu, chisina kusvibisa, chakachengeteka uye chine hutsanana, hachizokonzeresa kusvibiswa kwakakomba. Uyezve, bhegi retote rinowanzoiswa kune zvipfeko, zvipo, zvinyorwa uye zvimwe zvinotaridzika zvakanaka, kurongedza zvine fashoni uye zvinotaridzika, zviri nyore kutakura, zvinofarirwa nevanhu.
3.Self-adhesive mabhegi
Mabhegi ekuzvinamira anonziwo mabhegi anonamira, ega-adhesive mabhegi epurasitiki, OPP, PE uye zvimwe zvinhu zvekugadzirwa kwezvinhu zvikuru. Nekuda kweiyo yakanaka yekudhinda mabhegi ekuzvinamira, anogona kudhinda akasiyana mapatani, saka kugadzira uye kugadzira chirimwa chave chiri kunze kwekurongedza kwezvigadzirwa zvakawanda, sechikafu, zvishongo, nezvimwewo.
Kune mamwe akawanda mamwe marudzi emabhegi epurasitiki, zvichienderana nekuti ndeapi zvikamu zvechikamu.
Ⅱ Mhando dzakajairika dzemidziyo
.
Mabhegi epurasitiki, mabhegi ekurongedza epurasitiki ave zvinhu zvakakosha muhupenyu hwekugadzirwa kwevanhu, mabhegi epurasitiki aripo, mabhegi ePVC, mabhegi anoumbwa, mabhegi ekutsvaira, mabhegi ePVC ekurongedza, firimu repurasitiki uye mamwe marudzi anowanzo kushandiswa epurasitiki zvigadzirwa pamusika kudiwa, saka vhoriyamu yekugadzira yakakura kwazvo, mukugadzira nekugadzira mabhegi epurasitiki ekurongedza, mafekitori anowanzo sarudza mabhegi ekurongedza, mapurasitiki anowanzo sarudza?
Chekutanga, polyethylene ndiyo hombe hombe yemabhegi epurasitiki, zvigadzirwa zvepurasitiki, iyo inonyanya kukosha zvinhu, parizvino ndiyo yakanyanya kunaka pasirese yekubata chikafu mabhegi zvinhu, musika wemabhegi ekurongedza chikafu anowanzo kugadzirwa nezvinhu. Polyethylene mwenje uye yakajeka, ine yakakodzera mwando-uchapupu, oxygen-inodzivirira, acid-inodzivirira, alkali-resistant, kupisa chisimbiso uye zvimwe zvakanakira, uye isiri-chepfu, isingarapike, isinganhuhwi, zvinoenderana nekudya kurongedza hutano zviyero.
Chechipiri, polyvinyl chloride / PVC, parizvino ndiyo yechipiri yakakura pasi rose mhando dzepurasitiki mushure me polyethylene, ndiyo yakanakira sarudzo yemabhegi epurasitiki ekurongedza, mabhegi ePVC, mabhegi akaumbwa, mabhegi ekutsvaira, anogona zvakare kushandiswa kumabhuku, maforodha, matikiti uye mamwe mavhavha ekurongedza nekushongedza, nezvimwe.
Yetatu, yakaderera-density polyethylene ndiyo yakakura huwandu hwepurasitiki yekurongedza kudhinda indasitiri munyika dzakasiyana siyana, yakakodzera kuvhuvhuta nzira yekugadzira mumafirimu tubular, akakodzera kurongedza chikafu, zuva nezuva zvigadzirwa zvemakemikari kurongedza, fiber zvigadzirwa kurongedza, nezvimwe.
Chechina, high-density polyethylene, kupisa uye kupisa kwemhepo, kutonhora uye kutonhora kwechando, kunyorova, gasi, kushanda kwekudzivirira, uye haisi nyore kuputsa, simba repasi-density polyethylene kaviri, chinhu chinowanikwa kune mabhegi epurasitiki.
Chechishanu, biaxially oriented polypropylene firimu, simba rayo remuchina, kupeta simba, density yemhepo, hunyoro hunovharira zviri nani pane zvakajairika firimu repurasitiki, nekuda kwekubuda pachena kweiyi firimu repurasitiki rakanakisa, ruvara rwakaburitswa mushure mekudhindwa kwakawedzera kupenya uye kunaka, chinhu chakakosha chepurasitiki inoumbwa inochinjika kurongedza.
Yechitanhatu, shrink firimu zvakare yakajairwa substrate yemabhegi epurasitiki ekurongedza, ari kushandiswa neanopisa kurapwa kwemhepo kana infrared radiation inoderera, mushure mekupisa kupisa kwakanyatso kuputirwa mumidziyo yakaputirwa, simba rekutsikisa rinosvika pakukwirira kwayo muchikamu chekutonhora, uye rinogona kuchengetwa kwenguva yakareba.
Aya mabhegi epurasitiki, mabhegi epurasitiki ekurongedza, mabhegi anoumbwa, mabhegi ekutsvaira uye zvimwe zvinhu zvakajairika zvezvigadzirwa zvepurasitiki, nekuvandudzwa kwetekinoroji uye kuenderera mberi kufambira mberi, kushamwaridzana kwezvakatipoteredza, mabhegi epurasitiki ane hushamwari kwezvakatipoteredza, zvigadzirwa zvepurasitiki zvichava kutungamira kwemberi uye maitiro.
Magumo
Tichasimbirira kupa zvigadzirwa zviri nani uye sevhisi iri nani kune mutengi wedu.Kana paine rumwe ruzivo nezve zvigadzirwa zvaunoda kuziva, ndapota tumira kubvunza kwatiri kana kutiwedzera WhatsApp, isu tichakupindura iwe nekukurumidza. Tinovimba tinogona kuvaka hukama hwakanaka newe iwe unoverenga chinyorwa ichi. Ndinokutendai nekuverenga pano.
