Sixelela ukuba yeyiphi imibhobho kungcono ukukhetha ukufudumeza kunye nokunikezelwa kwamanzi.
Umbhobho wentsimbi ngokuthe ngcembe uye wangena kwimbali, enika indlela yokuphila ngakumbi, kunye ne-alogs engabizi. Njengakwizinto ngasinye zokwakha, zinezibonelelo zabo okanye izinto ezingalunganga. Ukukhetha iityhubhu zePolyproplene, imilinganiselo kufuneka ihlolwe ngononophelo kwaye ukwazi iileyibhile. Thatha ngayo kwaye uthethe.

Izimvo
Okokuqala, kubalulekile ukwazi ububanzi bezinto zePolypropylene zokubonelela ngamanzi kunye nokufudumeza. Kukho iintlobo ezininzi, bahlukaniswe nobunzima obunodonga, ukubala i-hydraulic kunye nolawulo lobushushu, olunokwazi ukulingana.
- I-PN 10-Banazo iindonga ezicekeceke, oko kuthetha ukuba kungcono ukungazinzanga zamanzi ashushu kunye nokusetyenziswa kubanda amanzi abandayo. Ngamanye amaxesha bayasetyenziswa xa kufakwa kumgangatho ofudumeleyo. Iimveliso ezinemakisha pn 10 zinokukhulisa ngokukhuselekileyo kubushushu bamanzi ukuya kuthi ga kwi-45 degrees kunye noxinzelelo oluphezulu lwe-1 MPA.
- I-PN 16 iqhubeka, uxinzelelo olusebenzayo ukuya kwi-1.6 MPA, kunye nobushushu bamanzi acetyiswayo ukuya kwi-60 ° C.
- PN 20-Njengoko ubumnandi obunobunzima bunyuka, izikhombisi ziyakhula. Apha unokuseta ukuya kuma-80 amaxabiso obushushu emanzini kwaye uvavanye uxinzelelo lwe-2 MPA.
- I-PN 25 yeyona ndlela yomeleleyo. I-95 isidanga esimalunga namanzi abilayo siyagcinwa, kunye nokusebenza ngokuzolileyo ngengcinezelo ye-2.5 ye-MPA.
Ukongeza kwezi zikhombisi, oko kukwisiko ukwahlula izakhiwo ezikumgangatho omnye kunye ne-multilayer. Inketho yesibini ixhotywe nge-fiberglass, i-foil kunye ne-basalt fiber. Kutheni uyifuna? Ukunyanzeliswa komaleko kune, enyanisweni, zonke ezi zongezi zivumela iindonga zihlale zihlala ngakumbi, kwaye ke kufuneka zihlale zikhoboka kakhulu, ubushushu buye. Umngcipheko wokwandiswa ubungakanani bamanzi ashushu kuncitshisiwe, okwenzeka rhoqo xa besebenza nePolypropylene.
Ungayimpazamo njani xa ukhetha ubungakanani
Yintoni ekufuneka uyazi, ukuya kwivenkile yokwakha iimpahla? Ukuqala ngemeko yokusebenza. Ngaba olu fakelo luya kufakwa amanzi ngamanzi okusela? Okanye ngaba ucwangcisa ukufudumeza, okanye umgangatho ofudumeleyo? Ndikholelwe, kuzo zonke ezi meko zidayi, ubungakanani bezinto ezifanelekileyo zemibhobho yePolyproplene kwi-mm ziya kwahluka. Kungenxa yoko le nto ithengwa ngamalungu phantsi komsebenzi othile wokwakha. Ukongeza kumsebenzi osisiseko, kubalulekile ukuba uqwalasele ukuba ngaba ukufudumeza kwigumbi apho ufakelwa khona.
Iimpawu kunye neenketho zokusetyenziswa
Ukuqonda ngokukhawuleza ukuba yintoni oyifunayo, kungcono ukubhekisa etafileni yemibhobho yePolyproplene. Kufuneka ufumane iqondo lobushushu lenzala, ubukhulu kukumakisha okuhambelana nezalathisi ezinqwenelekayo kuya kuba sisikhokelo sakho.Imibhobho ye-polyproplene yemibhobho ye-polyproplene e-intshi kunye ne-mm icacisiwe - oku kwenzelwa ukunceda, kuba abavelisi bamazwe ahlukeneyo banenkqubo yabo yembopheleleko.
Iinketho zemveliso ngokuxhomekeka kwiimpawu zokusetyenziswa
- RRL-HOMOPLYS, kufanelekile ukusebenzisa amanzi abandayo kuphela.
- I-RRV-ibhloko ye-copolymers, zilungile kumanzi abandayo, ngamanye amaxesha zisasetyenziswa xa kufakwa kumgangatho ofudumeleyo.
- I-PPR yindawo ye-polypropylene, eyona mbonakalo ithandwayo, inokunxibelelana namanzi ashushu, abandayo, kumgangatho oshushu okanye ukufudumeza.
- I-PPs yindlela ephuculweyo yokunganyangekala kobushushu obuphezulu. Kufunyanwa kwizakhiwo zasekhaya.

Ukubeka ubonelelo lwamanzi ngamanzi abandayo, kubandakanya nokusela, iimveliso ezixineneyo ezifanelekileyo nge-PN10. I-pipeling yekhaya ayinayo imimandla ephezulu yoxinzelelo, njengommiselo, ayikho inkulu kune-1 MPA, kunye nobushushu bamanzi asezantsi abuveli ukwanda komgca.
Imibhobho yePolypropylene yokufudumeza, ubungakanani beetafile ezingentla, kunqweneleka ukuzisebenzisa ngocoselelo nge-foil okanye i-basalt. Ele meko yavela kutshanje emarikeni kwaye zimbalwa abantu ababesebenza naye, kodwa izinto ezibonakalayo zineziphononongo. Kutheni ndifuna ukuqiniswa? Le yinxalenye ebaluleke kakhulu ekusekweni kwamanzi ashushu, kuba ngenxa ye-garket xa ityhilwe kubushushu obuphezulu, i-propylene ayitshintshi imilo yayo kunye nobungakanani bayo. Kwaye oko kuthetha ukuba akuyi kubakho ngxaki sinokubangela ukuvuza. Ububanzi bayo bangaphakathi bemibhobho yePolyProphene, itafile eboniswa ngaphezulu, iba ngaphantsi, kodwa iinkcukacha zihlala zingatshintshi.
Imigaqo kunye neengcebiso eziluncedo
- Uyilo olulula luyinto engatshatanga. Ukuzinzisa, kuqala imveliso inqunyulwe ngemibhobho yokusika i-Pipe, jika imiphetho kwaye udibanise uyilo usebenzisa i-fittings okanye iglu.
- I-Multilayer iphakanyiswe kunye nokwahlulahlula kuphela-xa usebenza nabo ayinakusetyenziswa i-welding ebandayo, ayizukubonelela ngonxibelelwano kuwo onke amacala. Ngokwesiqhelo, iinxalenye ezinamacala amaninzi ziqhagamshelwe nge-welding eshushu okanye isebenzise izixhobo ezizodwa.
- Imibhobho yokuqikelela ifuna ukulungiswa okukhethekileyo ngaphambi kofakelo. Into kukuba i-foil ye-aluminium iqhotyoshelwe kwi-fiber kwiglue, oko kuthetha ukuba kukho umngcipheko othile wokuphosa. Ukuthintela oku, ngaphambi kokuba uvelise imveliso kunye nokuqiniswa kwe-foil ye-aluminium, kuyimfuneko ukugcina isiphelo sendlwana sivela kumda, kwaye emva koko ubiza amacala omabini. Ngokhuseleko olunjalo, amanzi akasayi kuphinda angene, okuthetha ukuba umbhobho uya kuhlala unenombolo.
Yintoni onokuyijonga ekukhetheni kwezixhobo
Njengommiselo, izinto ezifanelekileyo ze-proplenene zenziwe nge-thermoplast. Ezi zixhobo zinovelwano kakhulu kubushushu behla kwaye zinokupheliswa xa zivezwa bubushushu. Yiyo loo nto kufuneka ukhethe izinto ngononophelo olukhethekileyo. Ungaze wenze impazamo?
- Amanzi ashushu, i-protutings ye-proits ayiyi kuhambelanayo. Bangalunganga xa becinezelekile kwaye banokubangela ukuba uqhawulo-mpilo. Kungcono ukusebenzisa iMelika - indlela edityanisiweyo yenziwa lula, oko kuthetha ukuba iya kuba lula kweli meko.
- Qiniseka ukuba ujonga ngokumakisha kunye ne-Gost xa uthenga imveliso-kufuneka ithethe ngokuchanekileyo kulo lonke uyilo. Umzekelo, ukuba usebenza ngokuthengisa, kubalulekile ukukhetha zombini iimveliso kwizinto ezifanayo.
- Sukuthenga izinto eziguqulweyo, zenziwe okanye zinamafutha aqhekekileyo. Izinto ezincinci ongazenzisiyo zinokubangela ukuqhekeka kwamanzi.
