Polypropylene tube, luqiniswe ingilazi endwangwini, for bafudumale. Izici, ngebuhle nebubi

Ngezinye ilungiselelo yesimanje Ukushisa izinhlelo zisebenzisa zokuxhumana ekhethekile. Okuvame kakhulu namuhla tube polypropylene, luqiniswe ingilazi fibre, intengo zazo ziyahlukahluka kusuka ruble 51 kuya 144. I-TDG. m. Ukucaciswa kobuchwepheshe wale mikhiqizo zikuvumela ukuzisebenzisa ezindaweni eziningi ephezulu lokushisa.

Izinzuzo main

Polypropylene tube, luqiniswe ingilazi endwangwini, for amalahle sebuningini izici ezinhle. Phakathi kwabo:

• isisindo ongaphakeme;
• amandla;
• akukho ukwanda ukusebenza.

Ngenxa yokuthi le mikhiqizo abe nesisindo ongaphakeme, zingabantu elula kakhulu ukukhweza kwezokuxhumana izinhlelo ngokuzimela. Phakathi kwezinye izinto, amandla abo evumela ukuba akhuthazele nokhahlo lokushisa izinguquko. Inqawe ube nokuvumelana nezimo eliphezulu. Yingakho ngosizo kubo ungakwazi ukuhlomisa i izinhlelo zomthetho eziyinkimbinkimbi. On ezindaweni zawo elingaphakathi isikhathi ayikhuphuki okuseleyo amaminerali ukuthi kungenziwa ngokuthi a plus elikhulu.

Ububi main

Polypropylene tube, luqiniswe fiberglass (Ukushisa), has eyodwa ethile ebalulekile. Lubonakaliswa izinga lokushisa elinganiselwe ngesikhatsi kokuhlinzwa. Kuyinto elilingana 95 ° C. Uma lo mkhawulo izondlulwa, futhi izinga lokushisa uyofinyelela 140 ° C, uhlelo iphayiphi omane kwancibilika. Ukuze ugweme izinkinga ezifana, umkhiqizi kuqinisa metal umkhiqizo.

serekhodi

Ukuqinisa kuyindlela yokuqinisa izinhlelo zokuxhumana. Ukuze wenze lokhu, aluminium isetshenziswa main. Positioning kungaba phakathi nangaphakathi. Kulo mBhalo kungenzeka ukufezekisa imiphumela emihle, njengoba kukhona awokuthi kwezindonga engaphakathi kuzokhulisa usawoti imali. I plastic ezivamile luqiniswe aluminium phakathi.

Imininingwane German kwagcizelela amapayipi

Okuvame kakhulu tube muva nje polypropylene. Okuhlezi emqondweni 25 mm ububanzi, isibonelo, iyobe iwufanele ruble 83. I-TDG. m. Eminyakeni yamuva, ethandwa kakhulu amapayipi German ukuthi ziyaqiniswa nge glass fibre maphakathi. imikhiqizo enjalo abe Coefficient abalulekile ukunwetshwa. Kuyinto Kr = 0,009 mm / m. Ngo amapayipi kufanele izindonga mkhulu uma ziqhathaniswa imikhiqizo luqiniswe aluminium ucwecwe.

Ziyakwazi efanelekayo ekuhlobiseni amanzi ashisayo ompompi futhi bafudumale izinhlelo, ezifana ukufakwa Ukushisa phansi noma Ukushisa, kanye inhlangano amanzi. Bayakwazi sikhuthazele izingcindezi kuze kube izikhathi eziphindwe eziningana, njengemicu yensimbi Ompompi basemgwaqeni. Amazinga medium ukusebenza ongafinyelela 120 ° C ngenkathi ukubaluleka standard 95 ° C.

Izici Main entsha polypropylene amashubhu PPRC, fiberglass kwagcizelela

Polypropylene tube, luqiniswe ingilazi endwangwini, has ukusebenza umxhwele for bafudumale. Phakathi kwabo, - kwabantu okuyinto 0.9 g / cm ^3. Kufanele kuqashelwe ukuncibilika lokushisa - 1490 ° C. amandla eqine kuhluka 34 kuya 35 N / MMA, kuyilapho ukucindezeleka isivuno kungaba ulingana 24 kuya 25 N / mm. ukunwetshwa Linear kuyinto 0.15 mm / m, kodwa conductivity ezishisayo at 200 ° C 0.24 W / m. Specific ukushisa umthamo ngesikhathi esifanayo lokushisa level 2 kJ / kg. amapayipi ezinjalo ingasetshenziswa hhayi nje ngobe kutawutfutfukisa ilungiselelo Ukushisa, kodwa futhi ekuqhubeni ukufaka ezisebenzisa umoya onomfutho. Le mikhiqizo Site iphayiphi amanethiwekhi asetshenziselwa ngokuya kwezolimo nasezimbonini.

Izici sandwich fiberglass ipayipi of PP-R

Uma unesithakazelo polypropylene amapayipi, luqiniswe ingilazi fibre, Ukushisa ke ungase ucabangele abakhiqizi ezimbalwa, ezifana isiNtaliyane, Czech, Turkish, isiJalimane kanye isiRashiya. Esimweni sokuqala, tube kungenziwa eziqhutshwa ezindaweni zokuphuza utshwala 20. Ngesikhathi esifanayo izihloko Czech, Turkish, isiJalimane kanye isiRashiya ukukhiqizwa eyenzelwe 25 ibha esimweni sokuqala. Futhi 20 ibha - e bonke abanye. Umkhawulo yokusebenza lokushisa amapayipi isiNtaliyane, Czech, ukukhiqizwa Turkish, isiJalimane kanye isiRashiya 950, 800, 950, 900 no 1100 ° C ngokulandelana. Ngayinye yalezi imikhiqizo has impilo inkonzo efanayo, okuyinto iminyaka engu-50.

Uma sicabangela lezi amapayipi ngokoMthetho ububanzi elingaphandle, esimweni sokuqala ingahluka 20 kuya 63, okwesibili - kusuka 16 kuya 125, wesithathu - kusuka 20 kuya 110, e yesine - kusuka 20 kuya 125, futhi lesihlanu - kusuka 20 kuya 110 mm. amapayipi anjalo enziwa kwe-polypropylene luqiniswe ingilazi fibre, intengo zazo ufaneleke izici ingase isetshenziselwe Ukushisa asizayo namanzi yasekhaya ashisayo. Ukuze ubone umkhuba wabo, nqampuna umhlabeleli, kubalulekile ukuthobela nehhanisi, asebenyukile obonakaliswe exclusion ungqimba oluphakathi nendawo yokugcizelela contact ngamanzi. Phakathi kwezinye izinto, phakathi nokufaka kunconywa ukusebenzisa Milling umsiki ekhethekile.

nemibi ezengeziwe

Uma ukhetha ukhweze Ukushisa polypropylene amapayipi, kufanele bajwayelane nemibi zabo eziyinhloko. Basuke obonakaliswe umthelela ongemuhle emisebeni ultraviolet ku umkhiqizo, kanye ukunwetshwa komugqa. Imisebe yelanga umthelela okumayelana isakhiwo se-polymers, futhi ngemva laying kubo ayikwazi imikhiqizo ngaphandle kumele zivikelwe. Yini embi ngalo kungenziwa ngokuthi kanti ukwanda komugqa. Likhulu ngokuphindwe kabili uma kuqhathaniswa metal amapayipi. Isici yokugcina kuholela isidingo ukuqinisa.

Imikhiqizo oluqanjwe extrusion double. On uzimele kwagcizelela zokumiswa ingcindezi emaceleni yangaphandle futhi kwangaphakathi lisetshenzisiwe polymer Thermoplastic. Plastics emoyeni uthatha nobulukhuni. Futhi ekugcineni ukuphatha ukwakha ubuhlobo obuqinile luhlaka okuqinile.

Yini okunye okufanele banake?

amapayipi epulasitiki Okuhlezi emqondweni, izici zazo okusesihlokweni esithi, abe skeleton eqinile ngesimo ingilazi zesivikelo sesifuba. Sandwich ezakhiwe babe yangaphandle futhi isendlalelo kwangaphakathi wenza kusukela polypropylene kanye nokuqinisa indlela enhle ingilazi fibre kumiswa. Phakathi extrusion, izinto ziya sintered ibe ikhekhe okuqinile futhi yakha umzimba ipayipi. imikhiqizo ezinjalo plastic ngaphezulu, futhi ubukhulu babo bangase ukufinyelela 125 mm.
