HDPEle PVC

Lisebelisoa tsa polasetiki li rekere haholo ebile lia bonolo. Li ka bōptjoa, tsa hatelloa kapa tsa etsoa ka libopeho tse fapaneng. Haholo-holo li entsoe ka oli le khase ea tlhaho. Ho na le mefuta e 'meli ea polasetiki; thermoplastics le thermoset polymers.

Le hoja li-polymer tsa thermoset li ka qhibilihisoa le ho bōptjoa hang feela 'me tsa lula li tiile ha li se li pholile, thermoplastics e ka qhibiliha le ho bōptjoa khafetsa, kahoo e ka sebelisoa hape.

Thermoplastics e sebelisetsoa ho etsa lijana, libotlolo, litanka tsa mafura, litafole tse menoang le litulo, lishelu, mekotla ea polasetiki, li-insulators tsa cable, liphanele tse thibelang likulo, lintho tsa ho bapala tsa letamo, upholstery, liaparo le lipeipi tsa metsi.

Ho na le mefuta e 'maloa ea thermoplastics,' me e khetholloa e le amorphous kapa semi-crystalline. Tse peli tsa tsona ke amorphousPVC(polyvinyl chloride) le semi-crystalline HDPE (polyethylene e phahameng haholo). Ka bobeli ke li-polymer tsa thepa.

Polyvinyl chloride (PVC) ke polymer ea vinyl e theko e tlaase ebile e tšoarella e sebelisoang mererong ea kaho. Ke polasetiki ea boraro e sebelisoang haholo ka mor'a polyethylene le polypropylene 'me e sebelisoa haholo ha ho etsoa liphaephe. E bobebe ebile e matla, e etsa hore e tuma haholo lits'ebetsong tsa lipeipi tsa metsi tse kaholimo ho fatše le ka tlas'a lefatše. E tiile haholo 'me e loketse ho patoa ka ho toba le ho kenya trenchless.

Ka lehlakoreng le leng, polyethylene e phahameng haholo (HDPE) ke polyethylene thermoplastic e entsoeng ka petroleum. E na le matla a holimo, e thata ho feta, 'me e khona ho mamella mocheso o phahameng.
Liphaephe tsa HDPE li loketse ho sebelisoa liphaepheng tse ka tlas'a lefatše, kaha ho fumanoe hore li kokobetsa le ho monya maqhubu a ts'oenyehileng, kahoo li fokotsa ho phahama ho ka amang tsamaiso. Li boetse li na le tse ntle ka ho fetisisa tse hanyetsanang le ho hatelloa ha manonyeletso 'me li na le maqeba a mangata le mocheso.

Le hoja lisebelisoa ka bobeli li le matla ebile li tšoarella, li fapana ka matla le likarolo tse ling. Ka lehlakoreng le leng, li etselitsoe ho mamella likhatello tse fapaneng. Ho finyella tekanyo ea khatello e tšoanang le ea pipe ea PVC, lebota la pipe ea HDPE le tlameha ho ba makhetlo a 2.5 ho feta pipe ea PVC.

Leha lisebelisoa ka bobeli li sebelisoa ho etsa li-fireworks,HDPEe fumanoe e loketse haholoanyane ebile e bolokehile ho sebelisoa hobane e ka thunya li-fireworks ho fihlela bophahamo bo loketseng. Haeba e hloleha ho qala ka har'a setshelo ebe e robeha, sets'oants'o sa HDPE se ke ke sa robeha ka matla joalo ka sets'oants'o sa PVC.

Ho akaretsa:

1. Polyvinyl Chloride (PVC) ke polymer ea vinyl e theko e tlaase le e tšoarellang e sebelisoang mererong ea kaho, ha High Density Polyethylene (HDPE) ke polyethylene thermoplastic e entsoeng ka petroleum.
2. Polyvinyl chloride ke polasetiki ea boraro e sebelisoang ka ho fetisisa, 'me polyethylene ke e' ngoe ea polasetiki e sebelisoang ka ho fetisisa.
3. PVC ke amorphous, ha HDPE e le semi-crystalline.
4. Ka bobeli li matla ebile li tšoarella, empa li na le matla a fapaneng le likopo tse fapaneng. PVC e boima le ho feta, ha HDPE e le thata ho feta, e thibane le abrasion le ho mamella mocheso.
5. Liphaephe tsa HDPE li fumanoe ho hatella le ho monya maqhubu a ts'oenyehileng, ka hona ho fokotsa ho phahama ho ka amang tsamaiso, ha PVC e sitoa.
6. HDPE e loketse haholo bakeng sa ho kenya khatello e tlaase, ha PVC e loketse ho pata ka ho toba le ho kenya trenchless.
