Imibhobho yePPR

Xa kuthelekiswa nemibhobho yentsimbi, iipayipi zePPR zineenzuzo zokufakela okulula, ukufakwa kwe-thermal engcono, kunye nokuchasana nokubola. Sisixhobo sonikezelo lwamanzi esisempilweni kwaye sihambelana nokusingqongileyo kwaye ikwayimveliso yonikezelo lwamanzi engundoqo kwimarike. Imibhobho ye-PPR ifumaneka kakhulu kule mibala ilandelayo, emhlophe, eGrey, eluhlaza kunye ne-curry imibala, kutheni kukho lo mahluko ikakhulu ubangelwa yimibala eyahlukeneyo ye-masterbatches eyongeziweyo.

Ukongeza kwiimpawu zemibhobho yeplastiki ngokubanzi njengobunzima bokukhanya, ukuxhathisa ukubola, ukunganyuswa, kunye nobomi benkonzo ende, imibhobho ye-PP-R nayo inezi mpawu zilandelayo eziphambili:

1 Ayinatyhefu kwaye icocekile.
Iimolekyuli zezinto eziluhlaza ze-PP-R ziyi-carbon kunye ne-hydrogen element kuphela, kwaye akukho zinto ezinobungozi kunye netyhefu. Icocekile kwaye inokuthenjwa. Ayisetyenziswa kuphela kwimibhobho yamanzi abandayo nashushu, kodwa nakwiinkqubo zamanzi okusela acocekileyo.

2 Ukugcina ubushushu kunye nokonga amandla.
I-thermal conductivity yepayipi ye-PP-R yi-0.21w / mk, eyi-1/200 kuphela yepayipi yensimbi.

3 Ukumelana nobushushu obungcono.
Indawo yokuthambisa iVicat yombhobho wePP-R yi-131.5 ℃. Ubushushu obuphezulu bokusebenza bunokufikelela kwi-95 ℃, enokuthi ihlangabezane neemfuno zesistim samanzi ashushu kwisakhiwo samanzi kunye nekhowudi yokuhambisa amanzi.

4Ubomi benkonzo ende.
Ngaphantsi kweemeko zokushisa okusebenzayo kwe-70 ℃ kunye noxinzelelo lokusebenza (PN) ye-1.0MPa, ubomi benkonzo ye-PP-R yombhobho inokufikelela kwiminyaka engaphezu kwama-50 (ngaphandle kokuba impahla yombhobho kufuneka ibe yi-S3.2 kunye ne-S2.5 series okanye Kaninzi); phantsi kobushushu obuqhelekileyo (20℃) Ubomi benkonzo bunokufikelela ngaphezu kweminyaka eyi-100.

5 Ufakelo olulula kunye noqhagamshelo oluthembekileyo.
I-PP-R inokusebenza kakuhle kwe-welding. Imibhobho kunye nezixhobo zinokudityaniswa ngokuncibilika okushushu kunye ne-electrofusion. Ukufakela kukulungele kwaye amajoyina athembekile. Amandla okudibanisa makhulu kunamandla ombhobho ngokwawo.

6 Iimathiriyeli zinokuphinda zisetyenziswe.
Inkunkuma ye-PP-R iyacocwa, yophulwe, iphinde isetyenziswe ekuveliseni imibhobho kunye nokufakelwa. Ubungakanani bezinto ezisetyenzisiweyo azidluli kwi-10% yemali epheleleyo kwaye ayichaphazeli umgangatho wemveliso.
