Ukufakwa kwemibhobho yeplastiki kunokwenziwa ngezandla zakho usebenzisa izixhobo ze-welding ezilula ze-fuse-free disting. Sixela njani.
Imibhobho yePolypropylene isetyenziswa ngokubanzi okwangoku ngokubeka imibhobho yamanzi kunye nemibhobho yeenkqubo zokufudumeza kumakhaya abantu.
Xa i PPP-imibhobho nolungiselelo ebushushwini kwi ukuguquka kwazo matshini nokudibanisa iintsimbi, depolymerization lasekuhlaleni ezinepolypropylene kwenzeka, yaye kukho ulungelelwaniso olwandeleyo imiphezulu ze imibhobho welding nokupholisa zabo, ukudibana izinto eziphathekayo kunye repo-isikali kwenzeka. Ngenxa yoko, xa zonke izinto ezibukhali zetekhnoloji ye-welding ziqwalaselwa, umphezulu obilini wemibhobho kunye nezixhobo ziba yinye yazo.
Icandelo lomdibaniso we-welded
Izixhobo zokwenza i-bubble ye-bubble ye-boble ye-polyproplene yemibhobho
Ukusebenza, uya kudinga:
- I-Truborez. Olona khetho luqhelekileyo sisikali semibhobho yokusika. Noko ke, umbhobho onjalo akuqinisekisi nokuba esibukhali kwaye ngokuyinxenye, ukuba ukugqabhuza umbhobho. Okungakumbi kufikelela ekufezekisweni xa usebenzisa imibhobho esekwe kwimibhobho yeplastiki. Ukungabikho kwesixhobo esikhethekileyo sokusika, ungasebenzisa isitya esinamazinyo amahle kunye nesitokhwe.
- I-shooter. Xa usebenzisa i ngakumbi metal ngefoyile ye ngefoyile xa ubilisa iinkqubo kunye namanzi ashushu ukuthintela ukwahlulwa ipipi iindonga ngexesha hydrodars kwiqondo lobushushu eliphezulu, kucetyiswa ukuba ukususa umaleko ngefoyile ye zangaphakathi ukuya ku-2 mm. Kwakhona, umthwali uyakuvumela ukuba ufumane i-brack clack crack kwaye ususe ukugquma okunokwenzeka.
- UMlawuli kunye nePensile. Umbhobho kufuneka ulinganiswe kwaye uqaphele ubunzulu be-welding welding. Ukuba awuyithobeli imibhobho yemibhobho kwi-fipes ngexesha le-welding, iirollers kwi-polypropylene inokulwa ngaphakathi, inqunyanyisiwe lumen zemibhobho. Kwakhona, amanqaku akwimibhobho kunye nezixhobo ziya kuba luncedo kwimibhobho ye-welding kwisikhundla esithile.
- I-nepkins yotywala. Indawo yokulala ye-polyproplene ityhutywe iphazanyiswe kwaye inyukele ukunqanda ukwenziwa kwe-capillary ihamba kubungqingqwa bezinto ezibonakalayo.
- Izixhobo ze-welding ezine-nozzles eziguquguqukayo (i-doplens). Kwiimeko ezininzi, kuya kuba lume umatshini oqhelekileyo kunye ongabizi kakhulu we-welding kunye nento efudumeleyo yesaphetha esixhonywe kwi-1 kw. Ezo zixhobo zinokubonelela nge-welding yemibhobho ene-diameter ukuya kuthi ga kwi-63 mm. Oomatshini bokuziqengqeleka belding babonakaliswa ngamandla amakhulu, ukuchaneka kohlengahlengiso lobushushu. Kananjalo, izixhobo zobungcali ngaxeshanye zifudusele ngaxeshanye izibini ze-diameter eyahlukeneyo ukuze zingachithi xesha xa kufakwa iidayimitha ezahlukeneyo. Ukulungiselela imibhobho ye-PPP kwindawo ezinzima ukuya kufikelela kumatshini we-welding enezinto ezinomngcipheko ojikelezayo, ezinokubekwa ngqo kunye ne-angle ye-90 degrees. Iziqalekiso zoomatshini abanolwazi lwe-welding zenziwa njengenani elinye elipheleleyo ngomngxunya wento yokufudumeza phakathi kwendawo yokudibana kunye noDorn. Xa ukhetha umatshini wokukhetha i-welding, kubalulekile ukuba unikele ingqalelo ekuthinteleni kwikhithi ukuba igqunywe nge-teflon anting onti-steyiting ontiyo (echongwe njenge-PTFE) ukuthintela ukunamathela kweplastiki kuguquko. Ukusetyenziswa kwekhaya, iimpawu ezimbini zokufudumeza zanele: i-Red (isalathi-mali esebomvu) kunye neGreen (isalathiso sokufumana iqondo lobushushu). Isithambiso solawulo lokufudumeza kufuneka sibe nenxaxheba ecacileyo kunye nokulungiswa okuhle kwindawo ekhethiweyo. Akuyi kubakho nkqwimpu egqithisileyo kwimo yokuma koomatshini we-welding: Ikuvumela ukuba ukhusele isixhobo ukuze ungahambi xa uqhagamshele.
Umatshini we-welding wemibhobho ye-polyproplene
Yeyiphi imibhobho yePolyProplene yokukhetha?
Ukusebenza kwiinkqubo zokubonelela zamanzi ezilula kwiimeko ezisezidolophini, unokukhetha imibhobho ye-PPP yabo nayiphi na abavelisi. Ukuhanjiswa kwamanzi okubandayo, imibhobho engafakwanga isetyenziswa, kwaye ukuhambisa amanzi ashushu-uqinisekisiwe nge-fipers okanye imibhobho ye-polyproplene ekhokelwa yi-0.3 mm kuphela ye-I-MM nganye, kwaye imibhobho engaqhelekanga ikhokelwa yi-1.5 mm).
Xa ukhetha imibhobho ye-PPP yokufudumeza kunye nokubonelela ngamanzi izindlu zelizwe ezizandleni zazo, kufanelekile ukubona ngokusondeleyo. Imibhobho ebiza kakhulu yenziwa kwi-polymer yanamhlanje, enobulungisa obungcono kwaye ichaze imiphumo yoxinzelelo olongezelelweyo. I-Polymers yongeza i-DYES eyandisa ukumelana nemiphumo kwimiphumo ye-UV, kunye ne-antioxididants ecothisile ukonakaliswa kwamachiza (ukwaluphala kweepolimers). Kwifoto: i-polypropylene yombhobho wamanzi
Kwakhona, imibhobho PPP eninzi abe fiberglass unyanzeliso, engaquki isandla kokwahlulwa ipipi iindonga ngexesha iziphene ukuwelda, njengokuba imibhobho kunye uqinisa ngefoyile ye metal. Imibhobho ye-PPP ebiza kakhulu i-PPP kulula ukwahlula kubunzima obuncinci beendonga zemibhobho kunye nokuqina okungcono, ngakumbi xa kupholile. Imibhobho enjalo ijongene nale ijongene nentreyithi yamanzi ngokungacwangciswanga kuyo - yolula ngaphandle kokuphazamisa ingqibelelo.

Njani ukulungisa umbhobho wePolyproplene ngezandla zabo
- Imibhobho ye-PPP kunye nezixhobo kufuneka zifumane ubushushu begumbi apho ziya kusebenza khona. Awungekhe ungenzi ngoko nangoko imibhobho ye-WED evela kubanda okanye ishushu lilanga.
- Bathezi efakwe kumatshini ukuwelda, amaqondo obushushu 260 ° C wahlala phantsi umlawuli. Ukufudumeza ngokukhawuleza, kufuneka ujike amaqhosha amabini. Xa iqondo lokusebenza lifikelelwe, i-bulb yokukhanya ikhuselwe. Isitshixo sesibini sicinyiwe emva koko.
- Imibhobho kunye nezixhobo zilungiselelwe i-welding: imibhobho yenziwa bubukhulu, amacandelo acetyiswa, ubunzulu be-welding buqatshelwe kwaye umphezulu weldied uhluka kwaye umphezulu weldied hlukahluka kwaye umphezulu wedlule.
- Xa iqondo lobushushu lifikelelwe kumatshini we-welding, amalungu e-weldided eza ezihlangwini ngaphandle kokujikeleza. Kamsinya nje umbhobho kunye nefanelekileyo baqalisa ukuba bayeke phezu kwiingxwabangxwaba - imizuzwana-7 (kuba pipe 25 mm) iqala: 21, 22, ... 27. Umbhobho ufudukela kwimakisha okanye ipensile (i-ipensile (i-nozzles ikuvumela ukuba uphindaphinde imibhobho enzulu kunexabiso elifunayo). Emva koko sikhupha umbhobho kwaye sifanelekile. Ixesha lokufudumeza kwemibhobho yeedayimitha ezahlukeneyo zinikezelwa kwitafile ebhalwe ngezantsi.
- Ngokukhawuleza nangaphandle kokujikeleza sidibanisa umbhobho kwaye kufanelekile. Musa slighten iimpawu kakhulu, kungenjalo ahambise amiliswe ngaphakathi, tiping le mithambo logwali.
- I-welding igqityiwe. Unxibelelwano olugqityiweyo kufuneka lunikwe ixesha 'lokudayala "- upholile ngemizuzu emibini (yombhobho ∅ 25 mm).
