Imhando ipi yepurasitiki inonzi PE?
PE (Polyethylene, Polyethylene) ndeimwe yeanonyanya kuzivikanwa thermoplastics anoshandiswa muindasitiri yemakemikari. Inoshandiswa zvakanyanya munzvimbo dzakasiyana siyana uye yave chinhu chesarudzo mumaindasitiri mazhinji nekuda kwehunhu hwayo hwakanaka hwemuviri uye hupfumi. Muchikamu chino, tichaongorora zvakadzama marudzi emapurasitiki ePE, zvimiro zvavo uye maapplication avo makuru kuti akubatsire kunzwisisa zviri nani izvi zvakakosha zvepurasitiki zvinhu.
Basic Overview yePE Plastics
PE plastiki (polyethylene) chinhu chepolymer chinogadzirwa ne polymerization ye ethylene monomer. Zvichienderana nedzvinyiriro uye tembiricha panguva yepolymerisation process, mapurasitiki ePE anogona kuiswa mumhando huru dzakati wandei senge low density polyethylene (LDPE), high density polyethylene (HDPE) uye linear low density polyethylene (LLDPE). Imwe neimwe mhando yePE plastiki ine yayo yakasarudzika dhizaini uye zvivakwa zveakasiyana mashandisirwo mamiriro.
Mhando dzePE mapurasitiki uye zvimiro zvavo
Low Density Polyethylene (LDPE)
LDPE inobudiswa ne-high-pressure polymerisation ye ethylene, iyo ine maketani akawanda emapazi muhutano hwayo uye naizvozvo inoratidzira dhigirii yakaderera yecrystallinity.LDPE inoratidzirwa nekunyorova kwayo, kuoma, kujekesa uye kupikisa kwemaitiro, uye inowanzoshandiswa mukugadzirwa kwemafirimu, mabhegi epurasitiki uye kurongedza zvokudya. Kunyangwe yakaderera simba uye kuoma kwayo, LDPE yakanaka mashandiro uye mutengo wakaderera zvinoita kuti ive yakakosha mukurongedza zvinhu.

High Density Polyethylene (HDPE)
HDPE ine polymerised pasi pekumanikidzwa kwakaderera uye ine yakawedzera mutsara mamolecular chimiro, zvichikonzera yakakwirira crystallinity uye density.Zvakanakira HDPE zvakanakisa kupikisa kwemakemikari, abrasion resistance uye tensile simba, nepo zvakare ine yakaderera permeability. Zvinhu izvi zvinoita kuti HDPE ishandiswe zvakanyanya mukugadzirwa kwepombi, midziyo, mabhodhoro uye zvinhu zvinodzivirira kemikari, pakati pezvimwe.

Linear Low Density Polyethylene (LLDPE)
LLDPE inogadzirwa ne-co-polymerising polyethylene ine zvidiki zvecopolymer monomers (eg butene, hexene) pakumanikidzwa kwakaderera. Inobatanidza kushanduka kweLDPE nesimba reHDPE, apo inoratidzira kukwirira kwepamusoro kupikisa uye kutambanudza.LLDPE inowanzoshandiswa kugadzira mafirimu ane simba guru, zvakadai semafirimu akatambanudzwa, mafirimu ekurima, nezvimwewo.

Nzvimbo huru dzekushandisa dzePE mapurasitiki
Nekuda kwekusiyana uye kwepamusoro kuita kwePE mapurasitiki, nzvimbo dzayo dzekushandisa dzakafara kwazvo. Muindasitiri yekurongedza, mapurasitiki ePE anowanzo shandiswa kugadzira marudzi akasiyana emafirimu epurasitiki, mabhegi uye midziyo yekurongedza. Mumunda wepombi, HDPE inowanzoshandiswa mukugadzirwa kwemvura uye pombi dzemvura, mapaipi egasi, nezvimwewo nekuda kwehutano hwakanaka hwemakemikari uye michina. Muzvigadzirwa zvemumba, PE mapurasitiki anoshandiswa zvakanyanya kugadzira mabhodhoro, midziyo uye zvimwe zvigadzirwa zvepurasitiki. Mumunda wekurima, LLDPE neLDPE anoshandiswa zvakanyanya kugadzira mafirimu ekurima kuti ape dziviriro yezvirimwa uye kuvhara kwevhu.
Kupfupikisa
Chii chinonzi PE plastiki? Iyo inoshandiswa zvakasiyana-siyana, ine mari uye inoshandiswa zvakanyanya thermoplastic. Nekunzwisisa marudzi akasiyana eP PE plastiki uye zvivakwa zvavo, mabhizinesi nevatengi vanogona kusarudza zvirinani zvinhu zvakakodzera kune zvavanoda. Kubva pakurongedza uye tubing kune zvigadzirwa zvemumba, PE plastiki inoita basa rakakosha muhupenyu hwazvino nemabhenefiti ayo akasiyana. Kana iwe uchivhiringidzika pakusarudza zvinhu zvepurasitiki, tinovimba kuti chinyorwa ichi chinogona kukupa ruzivo rwakakosha rwereferensi.
