Imhando ipi yepurasitiki inonzi PE? Tsanangudzo yakadzama yemhando, zvivakwa uye mashandisirwo epolyethylene (PE)
Chii chinonzi PE plastiki?
"Chii chinonzi PE plastiki?" Mubvunzo uyu unowanzo bvunzwa, kunyanya mumaindasitiri emakemikari nekugadzira.PE, kana polyethylene, inonzi thermoplastic yakagadzirwa nepolymerising ethylene monomer. Seimwe yemapurasitiki akajairika, PE inozivikanwa nekushandisa kwayo kwakasiyana uye kwakasiyana siyana kwekushandisa. Kudhura kwayo kwakaderera, purasitiki yakakwira uye kugadzikana kwemakemikari kunoita kuti ive chinhu chakakosha muindasitiri yemazuva ano.
Mhando dzePE Plastics
Polyethylene (PE) mapurasitiki akakamurwa kuva mapoka matatu makuru: yakaderera-density polyethylene (LDPE), yakakwirira-density polyethylene (HDPE) uye mutsara yakaderera-density polyethylene (LLDPE).
Low Density Polyethylene (LDPE)
LDPE i polyethylene ine chimiro chakanyanya kupararira, zvichikonzera kudzikira kwakadzika. Iyo inochinjika uye yakajeka uye inowanzoshandiswa mukugadzira mabhegi epurasitiki, firimu rekudya uye flexible packaging materials.

High Density Polyethylene (HDPE)
HDPE ine chimiro chakaomesesa chemolecular kupfuura LDPE, zvichiita kuti iwedzere kuwanda uye kupisa kwakanyanya uye kukanganisa kupikisa.HDPE inowanzoshandiswa mukugadzirwa kwezvigadzirwa zvepurasitiki zvakasimba zvinoshandiswa muupenyu hwezuva nezuva, zvakadai semabhodhoro emukaka, pombi uye matoyi.

Linear Low Density Polyethylene (LLDPE)
LLDPE inosanganisa kuchinjika kweLDPE uye kusimba kweHDPE nekutambanudza kwakanaka uye kuramba kubvarura. Inowanzo shandiswa kugadzira mafirimu akaomarara, akadai sekurima uye maindasitiri ekurongedza mafirimu.

Zvivakwa zvePE plastiki
Kunzwisisa "chii plastiki PE" kunoda kutarisa kwakadzama pazvinhu zvayo zvemukati. Polyethylene ine zvinotevera zvinosiyanisa hunhu:
Yakanakisa kugadzikana kwemakemikari
Polyethylene inopikisa zvakanaka kumakemikari mazhinji akadai seasidhi, alkali uye munyu. Nechikonzero ichi, PE zvinhu zvinowanzo shandiswa mumidziyo yemakemikari uye mapaipi.

High kukanganisa kuramba
Ese ari maviri epamusoro- uye akaderera-density polyethylene ane yakakwirira mhedzisiro yekupikisa, izvo zvinoita kuti zvive zvakanakisa pakurongedza uye kuchengetedza.

Kuiswa kwemagetsi
Polyethylene yakanakisa insulator yemagetsi uye inowanzoshandiswa muchivharo chekunze chewaya uye tambo kuve nechokwadi chekushanda kwakachengeteka kwemidziyo yemagetsi.

Zvishandiso zvePE mapurasitiki
Iyo yakawanda yekushandiswa kwepolyethylene inopindura zvakakwana mubvunzo "Chii chinonzi PE? Nekuda kwemhando dzakasiyana-siyana, PE zvinhu zvinotora nzvimbo yakakosha mune akati wandei maindasitiri.
Packaging
Polyethylene inoita basa rakakosha muindasitiri yekurongedza, kunyanya munzvimbo yekuchinjika kurongedza, uko PE mabhegi epurasitiki nemafirimu ndiwo anonyanya kushandiswa ePE muhupenyu hwezuva nezuva.

Kuvaka & Piping
Yakakwira density polyethylene (HDPE) inoshandiswa zvakanyanya muindasitiri yekuvaka yepombi, yekupa mvura uye gasi rekufambisa pombi nekuda kwekuora kwayo uye compression kuramba zvivakwa.

Mutengi uye Zvemumba
Mapurasitiki ePE anoshandiswawo muzvigadzirwa zvemazuva ese zvevatengi zvakaita sematoyi, zvinhu zvemumba uye midziyo yekuchengetera. Zvigadzirwa izvi hazvisi chete zvakachengeteka uye zvisina chepfu, asi zvinogona zvakare kudzokororwa kuderedza kusvibiswa kwezvakatipoteredza.

Mhedziso
Kupfupisa, mhinduro kumubvunzo "Chii chinonzi PE plastiki?" Mhinduro kumubvunzo uyu inovhara zvakasiyana-siyana zve polyethylene zvinhu uye zvakasiyana-siyana zvekushandisa. Sechinhu chakanyanya kugadzikana, chinogoneka uye chakaderera-mutengo wepurasitiki zvinhu, PE inoita basa rakakosha mune zvese zvemagariro emazuva ano. Kunzwisisa marudzi ayo akasiyana uye zvivakwa zvinogona kutibatsira kushandisa zvakanyanya chinyorwa ichi kusimudzira indasitiri uye mwero wekurarama.
