Nderudzi rwepurasitiki rakarukwa? Tsananguro yakadzama yemhando, zvivakwa uye zvikumbiro zve polyethyle (pe)
Chii chinonzi papurasitiki?
"Chii chinonzi purastic?" Mubvunzo uyu unowanzo bvunzwa, kunyanya mune zvemakemikari uye maindasitiri emakemikari.Pe, kana Polyethylene, iyo Thermoplastic yakagadzirwa nePolymerising Etser. Semumwe wePurasitiki akanyanya kuzivikanwa, pe inozivikanwa nekushandisa kwaro kwakasiyana siyana uye kwakasiyana siyana kwekushandisa. Mari yayo yakaderera, yepurasitiki yakakwira uye kuronga kwemakemikari kunoita kuti ive chinhu chakakosha muindasitiri yazvino.
Mhando dzePE PLASTICS
Polyethlene (pe) mapurasitiki akakamurwa kuita zvikamu zvitatu zvikuru
Low density polyethylene (LDPE)
Ldcpe ndeye polyethlene ine chimiro chakapararira zvakanyanya, zvichikonzera kuderera kwesimba. Iyo inoshanduka uye inoonekera uye inowanzoshandiswa mugadziri yemapurasitiki mabhegi, kunamatira firimu uye inochinja-chinja kurongedza zvinhu.

Yakakwira density polyethylene (HDPE)
HDPE ine chimiro chakasimba cheLDPE, zvichikonzera kusimba kwakanyanya uye kupisa kwakanyanya uye kukanganisa kuramba

Linear low denity polyethylene (LDLPE)
LLDPE inosanganisa kuchinjika kweLDPE uye Simba reHDPE neakanaka takatambanudza uye kubvarura. Izvo zvinowanzoshandiswa kugadzira mafirimu emafirimu, akadai sekurima uye maindasitiri ekutakura mafirimu.

Zvivakwa zvePurasitiki pepurasitiki
Kunzwisisa "Ndeipi mapurasitiki ipe" inoda kuti utarise zvivakwa zvayo. Polyethyle ine inotevera kusiyanisa maitiro:
Yakanakisa makemikari kugadzikana
Polyethyle ane basa rakanaka kumakemikari mazhinji akadai saAlids, Alkalis uye munyu. Nechikonzero ichi, pepa pezvinhu zvinowanzoshandiswa mumidziyo yemakemikari uye pombi.

Yakanyanya Kuipa Kupokana
Zvese zvakakwirira- uye zvakaderera-density polyethylene zvine yakanyanya kukanganisa kuramba, izvo zvinoita kuti vakunde pakutakura nekuchengetedza.

Magetsi insulation
Polyethlene inzvimbo yakanaka kwazvo yemagetsi uye inowanzoshandiswa muchifukidziro chekunze yemawaya uye tambo kuti ive nechokwadi chekushanda kwakachengeteka kwemidziyo yemagetsi.

Zvikumbiro zvePE PLASTICS
Yakakura huwandu hwezvekushandisa kwePolyethyle inopindura mubvunzo "Chii chinonzi?" Nekuda kwezvinhu zvakasiyana siyana zvakasiyana, pezvinhu zvinhu zvinogara chinzvimbo chakakosha mune dzinoverengeka maindasitiri.
Kurongedza
Polyethyle anotarisira basa rakakosha muindasitiri rekutakura, kunyanya munzvimbo yekuchinjika kwekuputika, uko mapurasitiki epurasitiki uye mafirimu ndiwo mafashama anonyanya kujairika ePE muhupenyu hwezuva nezuva hupenyu.

Kuvaka & Piping
Yakakwira density polyethy (HDPE) inoshandiswa zvakanyanya muindasitiri yekuvaka yekupomba, kuwanikwa kwemvura uye gasi kutapura mapaipi uye kumanikidza kudzivisa zvivakwa.

Vatengi uye zvinhu zveimba
Pe plasttics inoshandiswawo muzuva nezuva vatengi zvigadzirwa senge matoyi, zvinhu zveimba uye midziyo yekuchengetedza. Izvi zvigadzirwa hazvina kungochengeteka uye zvisina chepfu, asi zvinogona zvakare kudzoreredzwa kuti uderedze kusvibiswa kwezvakatipoteredza.

Mhedziso
Kuti ipfupise, mhinduro kumubvunzo "Chii chinonzi purasitiki?" Mhinduro kumubvunzo uyu inovhara kusiyana-siyana kwezvinhu zvePolyethylene uye huwandu hwavo hwekushandisa. Semunhu akagadzikana, anotyisa uye akajeka uye akaderera-epurasitiki zvinhu, ingoita basa rakakosha muzvikamu zvese zveruwa rwazvino. Kunzwisisa mhando dzaro dzakasiyana uye zvivakwa zvinogona kutibatsira kushandisa zvakanakisa kushandiswa kwezvinhu izvi kufambisira maindasitiri uye chiyero chekurarama.
