Polypropylene Random Copolymer PPR Pipes:Sistimi ea Phepelo ea Metsi ka Ntlong

Mokhabisong oa lapeng, khetho ea lipeipi tsa metsi a nooang ke ea bohlokoa. Tse tloaelehileng li kenyelletsa liphaephe tsa PE le Polypropylene Random Copolymer PPR Pipes. Hantle-ntle phapang ke efe pakeng tsa mefuta ena e 'meli ea liphaephe?

1. The Main Dmaikutlo Bpakeng tsa lipeipi tsa PE le lipeipi tsa PPR

1.1 Papiso ea ts'ebetso ea ho hanyetsa mocheso

Ha ho buisanoa ka phapang pakeng tsa liphaephe tsa PPR le lipeipi tsa PE, re qala ho tsepamisa maikutlo ho hanyetsa mocheso oa bona. Metric ena e amana ka kotloloho le botsitso le ho tšoarella ha lisebelisoa tsa liphaephe lits'ebetsong tse sebetsang. E 'ngoe, re tla shebisisa ts'ebetso e khethehileng ea mefuta ena e 'meli ea liphaephe mabapi le ho hanyetsa mocheso.

Liphaephe tsa metsi tsa PE li bontša mocheso o tsitsitseng tlas'a maemo a tloaelehileng a tšebeliso. E ka mamella mocheso o mongata oa 70 ° C le bonyane mocheso oa -30 °C. Ka har'a sebaka sena sa mocheso, Liphaephe tsa metsi tsa PE li ka boloka ts'ebetso e sireletsehileng le e tsitsitseng ka nako e telele.

Mocheso o tsitsitseng oa liphaephe tsa metsi tsa PPR tlas'a maemo a tloaelehileng a tšebeliso a hlakile ka ho lekana. Ka ho toba, e ka mamella mocheso o mongata oa 70 ° C le bonyane mocheso oa -10 °C. Ka har'a sebaka sena sa mocheso, Liphaephe tsa PPR li ka bontša ts'ebetso e sireletsehileng le e tsitsitseng kamehla. Ka ho bapisa, re fumane hore liphaephe tsa PE le liphaephe tsa PPR li etsa se tšoanang ka mocheso o phahameng, empa liphaephe tsa PE li ne li sebetsa hantle ka mocheso o tlase.

1.2 Phapang ea ts'ebetso ea bohloeki

Ha ho buisanoa ka phapang pakeng tsa liphaephe tsa PE le lipeipi tsa PPR, ho hlakile hore re hloka ho tsepamisa maikutlo tšebetsong ea bona ea bohloeki. Lisebelisoa tsena ka bobeli tsa liphaephe li bontša ts'ebetso e ntle ea bohloeki tlas'a maemo a tloaelehileng a tšebeliso, empa ts'ebetso ea bona e ka fapana maemong a itseng a ts'ebeliso. Sena se bonahala haholo-holo ka mamello ho maemo a fapaneng a tikoloho le botsitso ba lik'hemik'hale tsa thepa ka boeona. E 'ngoe, re tla hlahloba phapang e khethehileng ea ts'ebetso ea bohloeki pakeng tsa lisebelisoa tsena tse peli tsa liphaephe.

Liphaephe tsa PE li entsoe haholo ka polyethylene, ha liphaephe tsa PPR li entsoe haholo-holo ka propylene. Ha ho na phapang e khōlō pakeng tsa lisebelisoa tse peli mabapi le bohloeki le polokeho. Ntho ea bohlokoa ke hore na lisebelisoa tse tala tse sebelisoang ke khoebo li finyella litekanyetso, eseng thepa ka botsona. Ka hona, polelo ea koranta ea hore liphaephe tsa PE li hloekile ho feta lipeipi tsa PPR ha li na motheo. Liphaephe tsohle tse tšoanelehang tsa PE le PPR li tlameha ho etsa liteko tse tiileng tsa bohloeki, e leng tlhoko ea mantlha ea ho netefatsa boleng ba sehlahisoa.

1.3 Elastic modulus papiso

Ho na le phapang pakeng tsa lipeipi tsa PE le lipeipi tsa PPR. Le hoja ho se na phapang e khōlō pakeng tsa lisebelisoa tse peli mabapi le bohloeki le polokeho, li fapane ka lintho tse ling tsa 'mele tse kang elastic modulus. Ka hona, ha o etsa kgetho, ntle le ho nahana ka bohloeki le polokeho, litsupa tse ling tsa tshebetso le tsona li lokela ho nahanoa ho khetha thepa ea phala e lumellanang hantle le litlhoko tsa motho.

Modulus ea elastic ea lipeipi tsa PPR ke 850MPa. Ka papiso, modulus elastic ea liphaephe tsa PPR e phahame ho feta ea liphaephe tsa PE, e bonts'ang ho satalla ho betere le botle bo betere ba liphaephe. Liphaephe tsa PE, joalo ka polyethylene ea boholo bo mahareng, E na le modulus ea elastic e ka bang 550MPa, e bontshang ho tenyetseha hantle empa ho satalla hanyane hanyane. Sebakeng sa ho aha phepelo ea metsi, Liphaephe tsa PE li ka 'na tsa ameha mabapi le botle ba liphaephe ka lebaka la ho se otlolohe hantle, ho kobeha habonolo le deformation. Ho phaella moo, mabapi le conductivity ea mocheso, Liphaephe tsa PE lia fihla 0.42, e batlang e imenne habeli ea lipeipi tsa PPR.

2. Tshebetso Bho tsosolosoa ha PE liphaephe le liphaephe tsa PPR

2.1 Ts'ebetso ea welding

Ha ho nahanoa ka phapang ea ts'ebetso lipakeng tsa liphaephe tsa PPR le lipeipi tsa PE, re boetse re lokela ho ela hloko weldability bona. Mefuta e 'meli ea lipeipi e cheselitsoe ka tsela e fapaneng, kahoo li tla boela li bonts'e litšobotsi tse fapaneng lits'ebetsong tse sebetsang. E 'ngoe, re tla hlahloba ts'ebetso ea bona ea li-welding.

Leha liphaephe ka bobeli tsa PPR le liphaephe tsa PE li tšehetsa welding e qhibilihang ka ho chesa, Liphaephe tsa PPR li bonolo haholoanyane ho tjheseletsa. Liphaephe tsa liphaephe tsa PPR li pota-potiloe, athe tsa lipeipi tsa PE li sa tloaeleha, e ka bakang mathata a ho koala. Liphaephe tsa PPR li hloka ho fihla 260 ° C bakeng sa ho cheselletsa, ha liphaephe tsa PE li hloka 230 °C. Ke habohlokoa ho hlokomela hore ho sebelisa mochine oa tjheseletsa oa pipe ea PPR o fumanehang 'marakeng ho ka lebisa ho lutla ka lebaka la ho tjheseletsa ho feteletseng.. Holim'a moo, kaha thepa ea phala ea PE e na le oxidizing, hoa hlokahala ho sebelisa sesebelisoa se khethehileng ho tlosa sekala sa oxide holim'a metsi pele ho welding ho etsa bonnete ba hore phala e kopantsoeng e le kannete e ka thehoa 'me kahoo ho qoba mathata a ho lutla., empa sena se boetse se eketsa ho rarahana ho itseng kahong.

2.2 Ho hanyetsa tšusumetso ea mocheso o tlase

Liphaephe tsa PE li bontša molemo oa tsona tabeng ena. Leha liphaephe tsa PPR li le matla ho feta lipeipi tsa PE, Liphaephe tsa PE li na le maemo a betere, e laolwang ke semelo sa tlhaho. Ka lebaka la thepa ea thepa, Liphaephe tsa PE li na le matla a ho hanyetsa mocheso o tlase. Leha ho le joalo, ho hatisa ho brittleness ea liphaephe tsa PPR ka mocheso o tlaase ha ho bohlokoa, kaha liphaephe tsa PPR li 'nile tsa sebelisoa Chaena ka lilemo tse fetang leshome.

2.3 Boholo ba phala le ts'ebeliso

Ha u bapisa liphaephe tsa PE le liphaephe tsa PPR, hape re lokela ho ela hloko ntlha ea bohlokoa ea boholo ba phala. Le hoja lisebelisoa tse peli li na le melemo ea tsona ts'ebetsong, khetho ea boholo ba pipe e ama ka ho toba sephetho le litšenyehelo tsa morero. Ka hona, ha o etsa kgetho, lintlha tse fapaneng li tlameha ho nahanoa ka botlalo ho ipapisitsoe le maemo a ts'ebeliso le litlhoko tsa ho etsa khetho e nepahetseng ka ho fetesisa..

Hangata liphaephe tsa PE li sebelisoa bakeng sa drainage e kholo, ha lipeipi tsa PPR li sebelisoa haholo bakeng sa phepelo ea metsi. Boholo bo boholo ba liphaephe tsa PE bo ka fihla ho dn1000, ha boholo ba boholo ba liphaephe tsa PPR ke dn160. Ka hona, lits'ebetsong tse sebetsang, Hangata liphaephe tsa PE li sebelisoa bakeng sa liphaephe tsa drainage, ha lipeipi tsa PPR li sebelisoa haholo bakeng sa lipeipi tsa phepelo ea metsi.
