Inkqubo ukufudumeza lemibhobho ezinepolypropylene: eziluncedo kunye neempawu fakelo

Ukuza kuthi ga ngoku, ezinkulu-ukusasazeka inkqubo ye ukufudumeza ezinepolypropylene imibhobho. Oku kungenxa yokuba iimveliso ngemibhobho mihla abe nenani lwamathuba eziluncedo elingazange liye langaphambili (imibhobho PVC nokulinganiswa ezenziwe ene- polyethylene ephezulu).

buhle

Iimveliso Industrial ezenziwe ezinepolypropylene ixesha elide kakhulu. Ukuba ukhetha ngokuchanekileyo uhlobo olufunwayo, ukuba ingahlala iminyaka engama-50 okanye ngaphezulu. ngemibhobho Polypropylene, ngenxa ubume kunye necandelo lokuvelisa ubuchule ezizodwa, musa ifuna bala yokwambathisa ezongezelelweyo kwaye musa kuqokelela phezu komhlaba ngamanzi.

imali ubushushu xa usebenzisa ezi mveliso yi-20%. Ngemibhobho musa nomhlwa, hayi ukuyilwa ngaphakathi iidipozithi calcareous kunye nebhodi neendonga zangaphakathi koko ngokugqibeleleyo ezimkhuthuka, ishenxisa zochuku kunye ukuxhathisa, ngaloo ndlela amanzi aqukuqela ngokukhululekiyo kumbhobho. They are umqhubi umbane. Ngaphandle ukufudumeza evela netyhubhu ezinepolypropylene ekwaziyo withstanding amanqaku irekhodi lobushushu 95 ° C.

Products zilula ukuthutha kunye nofakelo, njengoko alula kakhulu kunentsimbi kwabo. kunqunyulwa lula izikere ezikhethekileyo. Ukufakelwa kwemibhobho ezinepolypropylene kwenkqubo zokufudumeza kuthatha ixesha elincinane. Kuba uqhagamshelwano phakathi umbhobho kunye nezilinganisi kufuna isixhobo ngelotha okhethekileyo. Kulo mzekelo, eziphelweni imveliso ngaphandle kwesidingo nokucoca. Ngenxa zokufudumeza Bazomelezela ambaxa imibhobho ezinepolypropylene uthathwa oluthembekileyo.

obandayo

Xa wayemenza imveliso, musa ukuveza igqwethwe okanye ukugoba njengoko ezinepolypropylene - kuyinto material nzima, nto leyo ethetha ukuba onke amathuba kunye nezinye iintshukumo kufuneka kwenziwe ngokusebenzisa lwezilinganisi ezinepolypropylene. umsebenzi wofakelo kungcono iingcali, kungenjalo kukho umngcipheko wokungenwa inkqubo zokufudumeza amahlwempu-esemgangathweni. Ukuba kuyimfuneko, umbhobho ezinepolypropylene ungagotywa kancinane, amalahle kwindawo ezinqwenelwayo ngokusetyenziswa kwesakhiwo yomile. Nangona kunjalo, xa kukho uxinzelelo olumandla kwimveliso eziphathekayo nise deformation okanye ukwaphula efanayo.

Okwangoku wavelisa ubude ityhubhu kweemitha 4. imveliso eyenziweyo kweendidi ezintathu, nganye kuzo yenzelwe isicelo esithile (PN10, PN20, PN25). Inkqubo zokufudumeza imvelaphi inyuselwa khona kwiityhubhu ezinepolypropylene, yenziwe PN25. Okunye olu hlobo ungachazwa ukuba tiyisiwa ngaphakathi ngefoyile ye-aluminiyam, ngoko, hayi zeplastiki. Ngenxa ityhubhu nokuqinisa zeqela lesithathu zingasetyenziswa noxinzelelo efikelela umoya-8 kunye namaqondo ukuya ku-70 ° C, apho ixesha - engama-50. Kodwa ke ukuba iimpawu uxinzelelo lwamanzi kunye nobushushu uya kwandisa ubomi ityhubhu iya kuncitshiswa.

isiphelo

ungathenga imibhobho ezinepolypropylene ukufudumeza kuyo nayiphi na ivenkile hardware. Ixabiso liphantsi kakhulu, nto leyo yenza ukuba zifumaneke. Iindleko ixhomekeke kwi sangqa (25 ukuya kwi-125 mm) kwaye isusela ukusuka ngama-40 1500 okanye ngaphezulu nganye square engange semitha. sele Uninzi kubonwa umgangatho ophezulu izinto kunye namaxabiso lwentando yesininzi.
