Nokunamathisela ngomthofu plastic: Amathuluzi, Technology

Amanzi kanye negesi amapayipi, eyenziwe ngepulasitiki, ngokushesha futhi ngokuqiniseka esikhundleni sensimbi yabo ngaphambili. Lokhu akusona isimanga, ngoba izici eziningana ezinjengolwazi zokukhulumisana ziyehluka isisindo ukukhanya, ukuthembeka, kalula ukufakwa. Nokho, uma ufaka ipayipi plastic Ngokuvamile kuye kudingeke Dala uxhumano by imiphumela ezishisayo emphethweni impahla. Ake sizwe indlela yokwenza nokunamathisela ngomthofu epulasitiki ukuthi amathuluzi angasetshenziswa ngalezi zinhloso.

Pike ezikhethekile Welding umshini

Nokunamathisela ngomthofu Plastic uhlobo 'nensimbi' equkethe imigodi amapayipi ka diameters ezahlukene. Emaphethelweni yokugcina ezibekwe ukuvuleka ezifanele, bese sishisiswe izinga lokushisa ukuncibilika.

nokunamathisela ngomthofu plastic wenziwa usebenzisa idivayisi ukulandelana elandelayo:

1. Isikhathi esiqondile sokuphela cut tube sifakwe Ukushisa emkhonweni. Idivayisi ixhunywe amapayipi. indiza Metal yoPhiko eliwu izinga lokushisa oyifunayo. Ngaphezu kwalokho, emaphethelweni tubing plastic kuthiwa kwancibilika.
2. Ngemva ukuthambisa okokusebenza tube evele asuswe enethiwekhi futhi oxhumene ku nokufakwa. Endaweni kokuzalela imiphetho kumelwe zibe kwatheleka enkulu impahla esibunjiweyo.
3. Ngaphambi ukwelashwa ezishisayo emaphethelweni elilandelayo ipayipi Welding umshini kahle bahlanza kusuka izinsalela impahla eqandisiwe.

Nokunamathisela ngomthofu plastic metal esishisayo

I elula kunazo, ezingabizi, kodwa kangako indlela ngokujoyina izakhi eyenziwe izihloko plastic - umphumela ezishisayo usebenzisa metal eshubile. Kulokhu kuba ukushisa ngokwanele le ucwecwe lwensimbi noma yimuphi omunye ithuluzi ofanele. Kugcine efiselekayo ukukhiya endaweni Vise, bese ukuncika ngokumelene ebusweni esishisayo izingxenye onqenqemeni. Uma Fusion kwenzeka izakhi izihloko ezifanele, kufanele asuswe ipuleti ocindezelwe ngokuqinile ndawonye.

Ngaphambi nokunamathisela ngomthofu eyenziwe ngepulasitiki ngale ndlela, kutuswa ukuhlanza ebusweni izingxenye kusuka kunoma iyiphi ezingcolisa okungase kuphazamise befikile impahla aminyene. Uma izinto kukhona amafutha singcoliswe, njengoba yokuhlanza ejenti kungukuthi zisebenzisa utshwala, acetone noma umoya emhlophe.

Nokunamathisela ngomthofu usebenzisa sikaphalafini igesi

Brazing plastic kungenzeka izandla zabo zenziwa igesi evuthayo lovela umlomo wombhobho sikaphalafini. Njengoba ukushaja kungaba lapha ukukhonza njengephayona nitrogen, isikhutha argon. Ukukhethwa uhlobo ketshezi gaseous incike izici plastic ekuthonyweni ukuncibilika. Prakthiza ebonisa ukuthi zezakhi esitebeleni kunazo phakathi kwenqubo ezishisayo izingxenye plastic compounds ivumela ukuthola Ukushisa argon noma nitrogen impahla.

Kwethulwa nokunamathisela ngomthofu ubuchwepheshe kwenza kubulawa imisebenzi futhi ngaphandle izithasiselo. Esimweni sokuqala wasebenzisa induku plastic ngenhloso ububanzi esingeqile 6 mm, okwenza kube nokwenzeka ukudala Fusion ngokwanele mncane, behlanzekile, kodwa ngesikhathi esifanayo umthungo eqinile. I okufakiwe kumele kwenziwe izinto ezifanayo ukuze ilungu yokuxhuma.

Uma usebenzisa igesi sikaphalafini at the ophumayo we umlomo wombhobho apharathasi lokushisa kufanele kugcinwe okungenani 50 ° ^C ephakeme kunaleyo ukuncibilika kwezinguzunga ukugeleza Inkomba indaba kusetshenzwe.

I processing ndlela efanele hhayi kuphela uma kudingeka ipayipi uxhumano, kodwa futhi lokhu ikakhulukazi ezimweni lapho ukululama bumper imoto, izakhi ingaphakathi, kwezinye izingxenye. Ezimweni ezinjalo ngokuvamile isetshenziselwa nokunamathisela ngomthofu plastic anezikhala okuyinto esikhulu ezindaweni ezilimele, ke wathela impahla esibunjiweyo.

nokomisa Brazing

Ukuze uxhumano izakhi plastic ukushisa efanelekayo isibhamu. Lapha, Ukushisa kwamanzi ukusebenza inikezwa ngokuxhuma apharathasi kuya amapayipi.

Nokomisa ngoba brazing yakhiwa indlela esihlinzeka ukusatshalaliswa umfaniswano emoyeni eliwu ebusweni workpiece. Ukuze kuqinisekwe ukuthi le Friend izinga uxhumano plastic izingxenye, zonke izinhlobo Imibhobho esemzimbeni esetshenziswayo yokuncibilikisa ithusi. ubungako bawo futhi ukuma akhethiwe kuye ngokuthi uhlobo izinto okufanele kusetshenzwe.

Nokunamathisela ngomthofu usebenzisa chemical kumakhemikhali awuketshezi

Ukujoyina izingxenye plastic nge indlela samanje kuhilela ogelezayo nokumanzisa impahla kuphela. Ngemva kwesikhathi esithile lona polymer iqala ukuba sikhukhumale ukuthola isakhiwo viscous. Ekugcineni-dock ngokwanele izakhi kanye isikhathi esithile ukuze ubambe ukubacindeza kuze kube ngomzuzu lapho umphetho uye lukhuni. Compounds ukuthola amandla ngemuva kwamahora ambalwa. Ukusheshisa le nqubo ovunyelwe nomthelela ebusweni ukushisa azinakwa, kanjalo usheshisa vaporization we kuphela kusukela isakhiwo Indwangu.

Kancane crystalline amapulasitiki amelana kumakhemikhali awuketshezi zamakhemikhali. Ngakho-ke, lapha emelelwa nokunamathisela ngomthofu ngeke kuphumelele. Ngokuvamile yakhetha lapho indlela isignali ukucutshungulwa izihloko ezenziwe kusukela thermoplastics amorphous.

Ukusetshenziswa kumakhemikhali awuketshezi kuphuma indlela ayibizi kokuphatha izingxenye plastic. Nokho, kutuswa ukuba aphendukele kuphela ezimweni ezimbi kakhulu uma kungekho kungenzeka ukusebenzisa ithuluzi ezikhethekile. Njengoba imithi yokususa ingcekeza elenkani e iningi eyinhloko esinobuthi ukuhwamuka eyingozi empilweni.

Ekuphetheni

Njengoba isiphetho kufanele kuphawulwe ukuthi plastic nokunamathisela ngomthofu ukufeza kangcono phambili lobani engaphakathi ezibonakalayo, kodwa kuphela nge ukushuba odongeni okungenani 5 mm. Ngemva solidification zezakhi wenziwa yokugcina ethi awafike evele kukhona emihle, shpaklyuyut futhi ukulungele for Umdwebo. Njengoba singabona, nokunamathisela ngomthofu plastic kuwumsebenzi ngempela ukuthi ingenzeka. Okubaluleke kakhulu - une amathuluzi adingekayo kanye senze kobukhulu ngokulandela imiyalelo.
