Sisenokuqhubeka nokubonelela ngezixhobo zokuqala nezisemgangathweni nokuba sifumene inzuzo encinci. UThixo uya kusisikelela ukuba senze ishishini lobubele ngonaphakade.

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.
