Polypropylene ishidi: izinhlobo kanye Ukucaciswa

isakhiwo kanye yokuqedela izinto Modern anezici ngokwanele ezinhle okukuvumela ukukhiqiza imikhiqizo ehlukahlukene eyinkimbinkimbi. Ngakho ishidi kanye polypropylene. Isetshenziselwa ezindaweni eziningi izenzo zabantu. Ngakho ingasetshenziswa ezindlini noma umkhakha.

Uyini ezibonakalayo?

Polypropylene ishidi - zokwenziwa yokwakha esesikhundleni Izakhiwo kakhulu, kanye inqwaba izinzuzo. Ngakho-ke, umfanekiso wanoma umkhiqizo odingeka kokubili ekhaya emikhulu ukwakhiwa.

Kunezinhlobo ezithile ezibonakalayo, ezingashabalala babe izakhiwo ezahlukene. Lezi zinhlobo wena sizoxoxa kamuva. Phakathi ukukhiqizwa amashidi izinto zokusetshenziswa kunezelwa ezahlukene yizici zamakhemikhali ezingathuthukisa ikhono izakhiwo ngokomzimba we material.

Material Imininingwane

Polypropylene ishidi anezakhi ezinhle ezenza kube elidumile:

1. Melting iphuzu - 165 degrees.

2. Ukumelana ngenyanga - abafika kwabangu-10 nowe.

3. Wugqinsi - 0,92 g / cc.

4. kuyaqina - 1.15 N / mm sikwele.

5. Thermal conductivity - 0,22 W / m * K.

Ngokulandelayo, siphendukela umbuzo izinzuzo uhambise umkhiqizo.

Izinzuzo Mkhiqizo

Polypropylene ishidi has izinzuzo ezilandelayo:

- Ezahlukene imibala kanye shades. Ngaphezu kwalokho, ishidi kungenzeka opaque noma obala. Okungukuthi, unekhono ukwenza ezihlukahlukene imihlobiso.

- ongaphakeme lokushisa ukuzinza, izinto nolaka, ukugqoka, isithwathwa.

- Ikhono ugcine ukuma.

- Izikhwepha High, lapho ishidi nezimo esimweni abandayo. Njengoba kulindelekile, ukuze ukwamukela kangcono ifomu kunesidingo, kungaba kancane eshubile.

- yokuhlanza Easy nokusingatha. Lokhu kwaziswa kulula ukusika, ukushefa. Kulokhu, ngeke ukuchitha nothuli oluningi. Sika izinto unga futhi grinder, kanye Jigsaw.

- High conductivity ezishisayo.

- okuphansi amanzi permeability.

- Imvelo abanobungane. Ngisho e inqubo kabusha obekuxoxwa akusho zingcolisa indawo esizungezile.

- isisindo okuphansi.

- Indaba cishe akusho ukuqhuba kagesi.

Polypropylene ishidi (izici zayo usuwazi) - ke ngempela safuna umkhiqizo elikuvumela ukuba uqaphele imibono boldest yezakhiwo.

Fields of kwesicelo

Manje kufanele sicabangele kabanzi nje indlela esetshenziswa lo mkhiqizo.

1. yokudla: ukwenziwa iziqukathi, kamuva tihlelwe okusamanzi (ubisi, amanzi) noma imikhiqizo.

2. umkhakha chemical: ukwenziwa iziqukathi, okuyinto ingagcinwa kahle imfuyo nolaka (alikhali acid).

3. Ehhovisi ivela kuye kwenziwa incwadi nesembozo, ezincwadini, amafolda kanye ezimvilophini.

4. Ukwakhiwa: tile okubhukuda, ukwakhiwa kwe-formwork isisekelo. Ngaphezu kwalokho, le nto kufanelekile ukwakhiwa amanzi nokushisa ompompi.

5. ukulima: polypropylene ekhiqizwa amabhodwe kakhulu futhi iziqukathi izithombo.

6. Ngaphezu kwalokho, le nto ukwenza pads kuhle obhavu kanye sauna.

Ngokuvamile, ishidi polypropylene, izici lobuchwepheshe zazo echazwe esihlokweni, wasebenzisa cishe kuyo yonke indawo.

imikhiqizo ehlukahlukene

Kufanele kuqashelwe ukuthi izinhlobo okokusebenza okungaka. Kukhona ezinye izinhlobo polypropylene:

- Tight. Kusukela ngokuvamile ekhiqizwa iziqukathi noma eminye imikhiqizo okuyiwona ukuqina kubalulekile. Ngokuvamile esetshenziselwa polypropylene ishidi amachibi ezinjalo.

- yeselula. Lisetshenziswa njengendlela material emabhokisini kanye nokwakhiwa.

- polystyrene. It livame ukusetshenziswa njengenhlangano impahla ukwahlukanisa.

Cabanga isitayela zakamuva ngaphezulu.

Izici Foam

Namuhla kuvamile impela. Iqiniso lokuthi umkhiqizo anezakhi esihle: okuhle ngaso iyavuleka umsindo vibration, ngaleyo ndlela avalele ukushisa. Ngaphezu kwalokho, ukwaziswa akusho kakhulu ukuncela umswakama, naphezu kwayo ngokohlu ukungena nakwamanye amazwe. Kuyinto ukukhanya kakhulu, ngakho-ke ingasetshenziswa zihlale zifudumele, hhayi kuphela izindlu olulodwa storey, kodwa futhi ephezulu liyaphuma.

Okuningi foamed polypropylene ishidi wavuma kakhulu esikhanyayo. Kulokhu, umoya asisho ukukhiqiza ezinobuthi. He is lula kakhulu ukusebenza. Kungaba iminyaka engaba ngu-20.

Isetshenziselwa umkhiqizo emelelwa kabanzi: I-zifudumele of izindonga isakhiwo ngaphandle kwe isangweji panel. amagoli wakhe ngaphakathi kwezindonga for kangcono umsindo ukumuncwa. Kusukela impahla ayikwazi ukudonsa amanzi, ingafakwa ezindaweni lapho kukhona umswakama high. Wayevame ukupakisha ezihlukahlukene izimpahla ethambile.

Izakhiwo machining impahla

Brazing ishidi polypropylene - umsebenzi akunzima kakhulu. Ngaphezu kwalokho, zonke izenzo kuyenziwa ngokushesha ngokwanele. Kubalulekile cabanga machining efanele komkhiqizo. Ngakho:

1. ithuluzi ukuthi kuzokwenziwa, kufanele ngensimbi kahle.

2. Ishidi ebusweni kufanele amboze kuphela emaphethelweni blade. Kulokhu, ukuzilimaza kuyoba esinembile.

3. Ngesikhathi kokuhlinzwa, udinga ukuqinisekisa ubumsulwa umkhiqizo. Lokho, namazinyo grinders kumele ngezikhathi ebugqilini shavings.

4. Futhi usadinga uqinisekise ukuthi thuluzi selehlile ngesikhathi. Kuyadingeka ukuze ngeke zincibilike emaphethelweni Imi.

Imikhiqizo ehlukahlukene Welding

Ngakho, ukuxhuma izakhi nomunye ngezindlela ezintathu:

- Polifuzionnaya ashiselwe polypropylene ishidi. It kubhekwa elilungile kakhulu futhi izinga. Ukuze lomkhiqizo womsebenzi sidinga idivayisi ekhethekile nokushisa emaphethelweni amashidi izinga lokushisa edingekayo. Ngaphezu kwalokho, kuthiwa sicindezelwe ngokunamandla ngokumelene nomunye. Ngemva Ukupholisa, omhlophe webhola okuhlala isikhathi eside kakhulu. isicelo Ngakho indlela esinjalo zezakhi kungaba noma iyiphi impahla kungakhathaliseki Uhlonze lwalo.

- Welding ne extruder. Ukuze afeze umsebenzi udinga eyengeziwe wire impahla. Kufanele kukhunjulwe ukuthi elibona nxazonke ithuluzi okwenziwa ngesandla. Ngokwemvelo, kulesi simo ngezinga eliphezulu kakhulu amandla akudingekile ukuba nethemba. Ezimweni eziningi, i extruder isetshenziswa uma kudingekile ukuze ujoyine amaphepha ukujiya ezinkulu.

- Welding ngesibhamu ekhethekile, ugunyaza agcwalise isisu ngomoya wasempumalanga. Nalapha futhi, sidinga Welding kwegatsha ekhethekile. Nokho, idivayisi akakwazi kulondolozwe izinga lokushisa eliphezulu emoyeni njalo. Lokhu kusikisela ukuthi umphetho ungathola incane kakhulu kunaleyo ephelele. Ngokwemvelo, nokunamathisela ngomthofu zezinhlamvu obukhulu polypropylene kulokhu angeke kubhekwe. I isibhamu kuyinto nje akwanele ukuxoxa omhlophe webhola kahle.

kakhulu inqubo Welding kumele kwenziwe ngokucophelela okwanele. Cabanga ikhwalithi kwegatsha. Ngokwesibonelo, uma kuba refractory, amandla ngokucindezela esiphethe isibhamu ukuba ukwanda weld. Ukuze kunenze nisondelane kuyinto qualitative, kufanele kahle sekuqala ukufudumala ithuluzi asizayo. Ngokwemvelo, izinga lokubanda kufanele libe iyunifomu.

Ukuze ukusebenza nokunamathisela ngomthofu, plate kumele exhunywe nomunye. Ukuze wenze lokhu, ungafaka isicelo ngocingo. Uma ngabe le indlela yokwenza lokhu kunzima, khona-ke enye indlela: smetyvanie nge die ekhethekile yakhelwe le nqubo.

Ngemva kokuphothulwa umsebenzi kufanele sinake ubumsulwa umphetho. Ngokwemvelo, ngesikhathi Welding kubonakala Foam ukuthi Uqinisa. Ngomqondo onabile, uma ayibonakali, omhlophe webhola akanayo ukusingatha. Nokho, kungaba ukuhlanza wena. Ukuze wenze lokhu, sebenzisa ngommese obukhali wanquma ukuthi kakhulu. Qaphela ukuthi lokhu kufanele kwenziwe ngokucophelela ukuze hhayi abaphazamisa ubuqotho kobuso ipuleti.

Yilokho zonke izici uyibhala polypropylene. Manje uyazi ukuthi kufanele iphathwe futhi yini izakhiwo ke anazo.
