1. Pipe ea merafo ea PE
Har'a li-plastiki tsohle tsa boenjiniere, HDPE e na le ts'ireletso e phahameng ka ho fetesisa ebile e tsebahala haholo. Ha boima ba limolek'hule bo phahama, ho na le moo lintho li ka kenang habonolo ho feta thepa ea tšepe (joalo ka tšepe ea khabone, tšepe e sa hloekang, boronse joalo-joalo). Tlas'a maemo a ts'enyeho e matla le ho tsofala ho hoholo, bophelo ba ts'ebeletso ke makhetlo a 4-6 a phala ea tšepe le makhetlo a 9 a polyethylene e tloaelehileng; Mme ts'ebetso e fetisang e ntlafatsoa ke 20%. Lelakabe le thibelang thepa le thepa ea antistatic li lokile ebile li fihlela litlhoko tse tloaelehileng. Bophelo ba ts'ebeletso bo tlase bo feta lilemo tse 20, ka melemo e makatsang ea moruo, ho hanela tšusumetso, ho roala le ho hanyetsa habeli.
2. Pipe ea likhoerekhoere ea PE
Pipe ea PE bakeng sa ho lahla likhoerekhoere e boetse e bitsoa phala ea polyethylene e phahameng, e bolelang HDPE ka Senyesemane. Mofuta ona oa phala o sebelisoa khafetsa e le khetho ea pele bakeng sa boenjineri ba masepala, e sebelisoang haholo indastering ea kalafo ea likhoerekhoere. Ka lebaka la ho hanyetsa ha eona, ho hanyetsa acid, ho hanyetsa ts'enyeho, mocheso o phahameng, ho hanela khatello e phahameng le litšobotsi tse ling, butle-butle e ile ea nkela boemo ba lipeipi tsa setso joalo ka lipeipi tsa tšepe le lipeipi tsa samente 'marakeng, haholo hobane phala ena e boima bo bobebe le bonolo ho kenya le ho fallela, 'me ke khetho ea pele ea thepa e ncha. Basebelisi ba lokela ho ela hloko lintlha tse latelang ha ba khetha lipeipi tse entsoeng ka thepa ena: 1. Ela hloko ka ho khetheha khetho ea lisebelisoa tse tala bakeng sa lipeipi tsa polasetiki. Ho na le limaraka tse likete tsa thepa e tala ea polyethylene, 'me ho na le lisebelisoa tse tala tse ka tlase ho li-yuan tse likete tse' maloa ka 'marakeng. Lihlahisoa tse hlahisoang ke thepa ena e tala li ke ke tsa hahuoa, ho seng joalo, tahlehelo ea rework e tla ba kholo. 2. Khetho ea baetsi ba lipeipi e tla ipapisa le baetsi ba semmuso le ba hloahloa. 3. Ha u khetha ho reka lipeipi tsa PE, hlahloba baetsi hang-hang ho bona hore na ba na le matla a tlhahiso.
3. PE ea phepelo ea metsi
Liphaepe tsa PE bakeng sa phepelo ea metsi ke lihlahisoa tse ncha tsa lipeipi tsa setso tsa tšepe le lipeipi tsa metsi a nooang a PVC.
Phala ea phepelo ea metsi e tlameha ho ba le khatello e itseng, 'me lehoakhoa la PE le nang le boima bo phahameng ba limolek'hule le thepa e ntle ea mochini, joalo ka lehoakhoa la HDPE, hangata le khethoa. LDPE lehoakhoa na tlaase tensile matla, futsanehileng khatello ea ho hanyetsa, ho se tenyetsehe futsanehileng, mafutsana tlhakore botsitso nakong bōpa le mabapi thata, kahoo, ho ke ke a loketse joaloka lintho tse bonahalang tsa phala khatello ea phepelo ea metsi. Leha ho le joalo, ka lebaka la index ea eona e phahameng ea bohloeki, PE, haholo-holo lehoakhoa la HDPE, e se e le sesebelisoa se tloaelehileng bakeng sa ho hlahisa lipeipi tsa metsi a nooang. HDPE lehoakhoa le tlaase qhibiliha e tiileng e qamathelang, fluidity e ntle le ho e lokisa e bonolo, kahoo qhibiliha index ea eona e na le mefuta e fapaneng ea likhetho, hangata MI e lipakeng tsa 0.3-3g / 10min.
