Parizvino, mabhegi epurasitiki anotengeswa pamusika anonyanya kukamurwa muzvikamu zvitatu maererano nemhando yezvigadzirwa: chikamu chekutanga ndeye polyethylene, iyo inonyanya kushandiswa kurongedza zvakajairika michero nemiriwo;chikamu chechipiri chinonzi polyvinylidene chloride, iyo inonyanya kushandiswa pakudya kwakabikwa., Hamu uye zvimwe zvigadzirwa;chikamu chechitatu polyvinyl chloride epurasitiki mabhegi.Polyvinyl chloride mabhegi epurasitiki anoda kuwedzerwa nezvinowedzerwa panguva yekugadzira.Izvi zvinowedzera zviri nyore kutama kunze kana zvichipisa kana kusangana nemafuta ane mafuta, uye anoramba ari muchikafu uye anokonzera kukuvadza kumuviri wemunhu.Saka, usaisa miriwo nezvimwe zvekudya muhombodo yepurasitiki.Pisa mu microwave, uye usaisa bhegi repurasitiki mufiriji.
Uye zvakare, bhegi repurasitiki rakagadzirwa chero chinhu chinofanirwa kushandiswa zvinoenderana nemhando yekushisa inotsanangurwa pane chigadzirwa kurongedza, uye bhegi repurasitiki harifanirwe kunge rakatarisana nechikafu kwenguva yakareba.Pakupisa, siya pakaputsika kana kuboora maburi madiki mubhegi repurasitiki.Kuti udzivise kuputika, uye kudzivirira kupisa kwakanyanya kwemhute yemvura kubva pakudya kubva muhombodo yepurasitiki.
Mukaka uri mubhegi rakafuratira wakachengeteka kunwa: Bhegi rakafuratira rinoshandiswa kurongedza mukaka harisi danga refirimu.Kuti uchengetedze kusimba kwemhepo, mabhegi epurasitiki akajairwa anogadzirwa neakawanda akaturikidzana efirimu, uye iyo yemukati layer ndeye polyethylene.Hazvizove dambudziko kunwa mushure mekudziya.
Mabhegi epurasitiki ane mavara haarongedze zvokudya zvinobva kunze kwenyika: Parizvino, mabhegi akawanda epurasitiki anoshandiswa nevatengesi vanotengesa muriwo nemichero pamusika ane zvishoma uye machena, asiwo matsvuku, matema, uye kunyange yero, girini, uye bhuruu.Mabhegi epurasitiki anoshandiswa kurongedza zvikafu zvakabikwa uye svutugadzike kuti zvidyiwe zvakananga.Zvakanakisisa kusashandisa mabhegi epurasitiki ane mavara.Pane zvikonzero zviviri: Chekutanga, mavara anoshandiswa kudhayi mabhegi epurasitiki ane simba rekupinza uye kusagadzikana, uye anobuda nyore kana akasangana nemafuta nekupisa;kana iri dhayi yeorganic, ichange iinewo mahydrocarbon anonhuwirira.Chechipiri, mabhegi epurasitiki mazhinji ane mavara akagadzirwa nemapurasitiki akadzokororwa.Nekuda kwekuti mapurasitiki akadzokororwa ane tsvina yakawanda, vagadziri vanofanirwa kuwedzera pigment kuti vavhare.
Maitiro ekuona kuvepo kwemasaga epurasitiki asina chepfu: mabhegi epurasitiki asina chepfu ane mukaka machena, anopenya, kana asina ruvara uye akajeka, anochinjika, anotsvedzerera pakubata, uye wakisi pamusoro;Mabhegi epurasitiki ane chepfu ane makore kana akareruka yeyero muruvara, Tacky kukubata.
Nzira yekuyedza mvura: Isa bhegi repurasitiki mumvura woridzvanya pasi pemvura.Iyo isiri-chepfu yepurasitiki bhegi ine diki chaiyo giravhiti uye inogona pamusoro.Iyo chepfu yepurasitiki bhegi ine yakakura chaiyo giravhiti uye kunyura.
Kuzunungusa nzira yekuona: bata imwe mugumo webhegi repurasitiki neruoko rwako woizunza nesimba.Avo vane ruzha rwakatsetseka havana chepfu;avo vane ruzha rwakagomara vane muchetura.
Nzira yekuona moto: kwete-chepfu polyethylene mabhegi epurasitiki anogona kupisa, murazvo webhuruu, kumucheto kwepamusoro kune yero, uye inodonha semisodzi yekenduru kana ichitsva, ine kunhuwa kweparafini, uye ine utsi hushoma;Chepfu PVC mabhegi epurasitiki haabatike uye anosiya moto.Inodzima, murazvo wakatsvuka, pasi pakasvibirira, yakapfava uye inogona kudhonzwa, nekunhuhwirira kwakashata kwehydrochloric acid.
