Ukwaneliseka kwabathengi yeyona nto sijolise kuyo. Sigcina umgangatho ohambelanayo wobungcali, umgangatho, ukuthembeka kunye nenkonzo kwiZitifiketi ze-ISO ezicacileyo eziphezulu I-Brass Male Insert ye-PPR Pipe Umbala weBrass Ixabiso eliphantsi, Sifumana umgangatho ophezulu njengesiseko seziphumo zethu. Ke ngoko, sigxila kumveliso kwiimpahla ezikumgangatho ophezulu. Inkqubo yolawulo lomgangatho oluqinileyo yenziwe ukuqinisekisa ubungakanani bempahla.
Ukwaneliseka kwabathengi yeyona nto sijolise kuyo. Sigcina umgangatho oqhubekayo wobungcali, umgangatho, ukuthembeka kunye nenkonzoi-ppr bross insert, Sihlala sigxininisa ekuphuhlisweni kwezisombululo, sichithe imali elungileyo kunye nabasebenzi ekuphuculeni ubuchwepheshe, kwaye siququzelele ukuphuculwa kwemveliso, sihlangabezana neemfuno zabantu abavela kuwo onke amazwe kunye nemimandla.

Imibhobho ye-PPR

Xa kuthelekiswa nemibhobho yesinyithi, imibhobho ye-PPR ineengenelo zokufakelwa okulula, ubushushu obungcono, kunye nokumelana nokugqwala. Yinto yokubonelela ngamanzi enempilo kwaye inobuhlobo nokusingqongileyo kwaye ikwayimveliso ephambili yokubonelela ngamanzi kwimarike. Imibhobho ye-PPR ifumaneka kakhulu ngemibala elandelayo, emhlophe, engwevu, eluhlaza kunye nemibala ye-curry, isizathu sokuba kubekho lo mahluko ubangelwa ikakhulu yimibala eyahlukeneyo ye-masterbatches eyongeziweyo.

Ukongeza kwiimpawu zemibhobho yeplastiki ngokubanzi ezifana nobunzima obulula, ukumelana nokugqwala, ukungakhuli, kunye nobomi benkonzo ende, imibhobho ye-PP-R ikwanazo ezi mpawu zilandelayo ziphambili:

1 Ayinabungozi kwaye ayicocekanga.
Iimolekyuli zezinto eziluhlaza ze-PP-R zizinto zekhabhoni ne-hydrogen kuphela, kwaye azikho izinto ezinobungozi nezinobuthi. Zicocekile kwaye zithembekile. Azisebenzi kuphela kwimibhobho yamanzi abandayo nashushu, kodwa nakwiinkqubo zamanzi okusela acocekileyo.

2 Ukugcinwa kobushushu nokonga amandla.
Ukuqhuba kobushushu bombhobho we-PP-R yi-0.21w/mk, eyi-1/200 kuphela yombhobho wentsimbi.

3 Ukumelana nobushushu okungcono.
Indawo yokuthambisa yeVicat yombhobho wePP-R yi-131.5℃. Ubushushu obuphezulu bokusebenza bungafikelela kwi-95℃, nto leyo enokuhlangabezana neemfuno zenkqubo yamanzi ashushu kwikhowudi yokuhambisa amanzi kunye nokukhupha amanzi kwisakhiwo.

4Ubomi benkonzo ende.
Phantsi kweemeko zobushushu obusebenzayo obuyi-70℃ kunye noxinzelelo lokusebenza (PN) lwe-1.0MPa, ubomi benkonzo yombhobho we-PP-R bunokufikelela kwiminyaka engaphezu kwama-50 (ukuba izinto zombhobho kufuneka zibe yi-S3.2 kunye ne-S2.5 series okanye ngaphezulu); phantsi kobushushu obuqhelekileyo (20℃) Ubomi benkonzo bunokufikelela kwiminyaka engaphezu kwe-100.

5 Ukufakela okulula kunye noqhagamshelo oluthembekileyo.
I-PP-R isebenza kakuhle ekudibaniseni. Iipayipi kunye nezixhobo zinokudityaniswa ngokunyibilika okushushu kunye nokudibanisa nge-electrofusion. Ukufakelwa kulula kwaye amalungu athembekile. Amandla elungu angaphezulu kwamandla elungu ngokwalo.

Izinto ezi-6 zingaphinda zisetyenziswe.
Inkunkuma ye-PP-R iyacocwa, iqhekezwe, ize isetyenziswe kwakhona ukuze isetyenziswe ekuveliseni imibhobho kunye nezixhobo. Ubungakanani bezinto ezisetyenzisiweyo abudluli kwi-10% yesixa siphela kwaye abuchaphazeli umgangatho wemveliso.

ufakelo

Ukwaneliseka kwabathengi yeyona nto sijolise kuyo. Sigcina umgangatho ohambelanayo wobungcali, umgangatho, ukuthembeka kunye nenkonzo kwiZitifiketi ze-ISO ezicacileyo eziphezulu I-Brass Male Insert ye-PPR Pipe Umbala weBrass Ixabiso eliphantsi, Sifumana umgangatho ophezulu njengesiseko seziphumo zethu. Ke ngoko, sigxila kumveliso kwiimpahla ezikumgangatho ophezulu. Inkqubo yolawulo lomgangatho oluqinileyo yenziwe ukuqinisekisa ubungakanani bempahla.
I-PPR kunye ne-Insert eneenkcukacha eziphezulu, sihlala sigxininisa ekuphuhlisweni kwezisombululo, sichithe imali elungileyo kunye nabasebenzi ekuphuculeni ubuchwepheshe, kwaye siququzelele ukuphuculwa kwemveliso, sihlangabezana neemfuno zabantu abavela kuwo onke amazwe kunye nemimandla.
