Mazuva ano, vanhu vari kunetseka zvikuru nezveutano hwavo. Vamwe vanhu vanowanzoona mishumo yenhau yekuti vamwe vanhu vanodya takeout kwenguva yakareba vanowanzosangana nezvinetso zvehutano. Nokudaro, ikozvino vanhu vanonetseka zvikuru pamusoro pekuti mabhegi epurasitiki ari epurasitiki ezvokudya uye kana achikuvadza kuhutano hwavo. Heano nzira shoma dzekusiyanisa pakati pemabhegi epurasitiki echikafu uye akajairwa mabhegi epurasitiki.
Zviri nyore kushandisa mabhegi epurasitiki chikafu nezvimwe zvinhu. Parizvino, pane mhando mbiri dzemabhegi epurasitiki pamusika, imwe yakagadzirwa nezvinhu zvakaita se polyethylene, iyo yakachengeteka uye inogona kushandiswa kurongedza chikafu, uye imwe ine muchetura, inogona kukuvadza kurongedza chikafu uye inogona chete kuva. inoshandiswa pakurongedza zvakazara.
Mabhegi ekurongedza chikafudzinowanzozivikanwa kwatiri semabhegi egiredhi rekudya, ayo ane zvakanyanya kuomesesa uye akakwira zviyero zvezvinhu zvavo. Isu tinowanzo shandisa chikafu-giredhi zvinhu kazhinji isiri-chepfu, ine hushamwari firimu sechinhu chikuru. Uye zvigadzirwa zvakasiyana-siyana zvine maitiro akasiyana, saka tinofanira kusarudza maererano nemaitiro ezvokudya pachayo panguva yekugadzirwa.
Ndeapi mabhegi epurasitiki ari giredhi rekudya?
PE i polyethylene, uye mabhegi epurasitiki ePE igiredhi rekudya. PE imhando ye thermoplastic resin yakagadzirwa ethylene kuburikidza ne polymerization. Haina hwema uye haina chepfu, uye ine yakanaka kwazvo yakaderera tembiricha kuramba (yakaderera kushanda tembiricha ndeye -100 ~ 70 ℃). Iine kugadzikana kwakanaka kwekemikari, asidhi uye alkali kuramba, uye hainyunguriki mune zvinonyungudutsa zvakajairika pakupisa kwakajairika. Iyo ine yakanakisa magetsi ekudzivirira uye kunyura kwemvura yakaderera. Mabhegi epurasitiki echikafu-giredhi anowanzo kupatsanurwa kuita akajairwa mabhegi ekurongedza echikafu, mabhegi ekurongedza echikafu, inflatable mabhegi ekurongedza echikafu, mabhegi ekurongedza echikafu akabikwa, masaga ekurongedza echikafu akabikwa, mabhegi ekurongedza echikafu uye zvichingodaro, nezvinhu zvakasiyana. Mabhegi epurasitiki echikafu akajairika anosanganisira PE (polyethylene), aluminium foil, naironi uye zvinhu zvinoumbwa. Mabhegi epurasitiki echikafu ane zvimwe zvakajairika kuti ave nechokwadi chekuti chikafu chiri chitsva uye chisina zvirwere nekuora. Imwe ndeyekuvhara zvachose organic solvent, girisi, gasi, mhute yemvura uye zvichingodaro; Imwe yacho ndeyekuve neakanakisa permeability resistance, mwando kuramba, kutonhora, kudzivirira kupisa, light avoiding and insulation, uye kuva nechitarisiko chakanaka; Yechitatu iri nyore kugadzira uye yakaderera mutengo wekugadzirisa; Yechina ndeyekuva nesimba rakanaka, mabhegi ekurongedza epurasitiki ane simba rakanyanya kuita pahuremu hweyuniti, anopokana uye ari nyore kugadzirisa.
Mabhegi epurasitiki echikafu uye akajairwa mabhegi epurasitiki kuratidza nzira
Ruvara rwekuona nzira, mabhegi epurasitiki ekuchengetedza anowanzo chena mukaka, anopenya, purasitiki iyi inonzwa yaiswa mafuta, inonzwa sekunge pamusoro pacho iwakisi, asi ruvara rwemabhegi epurasitiki ane muchetura kazhinji hamster yero, inonzwa kakunamira.
Kunyudzwa kwemvura nzira, unogona kuisa bhegi repurasitiki mumvura, kumirira kwechinguva kuti urege kuenda, uchaona akanyura muzasi memvura ane chepfu mabhegi epurasitiki, zvakapesana zvakachengeteka.
Moto nzira. Mabhegi epurasitiki akachengeteka ari nyore kupisa. Pakutsva, vanenge vaine murazvo webhuruu semafuta ekenduru, pane kunhuwa kweparafini, asi utsi hushoma. Uye mabhegi epurasitiki ane chepfu haabatike, murazvo wakatsvuka, kupisa uye kunyunguduka kunoburitsa silika, pachava nekunhuhwirira kunosemesa sehydrochloric acid.
Kunhuwa nzira. Kazhinji kutaura, mabhegi epurasitiki akachengeteka haana chero kunhuhwirira kusina kujairika, pane zvinopesana, kune kunhuhwirira, kunhuhwirira kunhuhwirira, izvo zvingave zvichikonzerwa nekushandiswa kwezvimwe zvinowedzera kana kuti unhu husina kunaka.
