PP-R bututu da kayan aiki dogara ne a kan bazuwar copolymerized polypropylene a matsayin babban albarkatun kasa da aka samar daidai da GB / T18742.Ana iya raba polypropylene zuwa PP-H (homopolymer polypropylene), PP-B (block copolymer polypropylene), da PP-R (bazuwar copolymer polypropylene).Injin bututun bango biyu yana taka muhimmiyar rawa wajen samar da bututu.PP-R shine kayan da aka zaba don bututun polypropylene don ruwan zafi da sanyi saboda tsayin daka na tsayin daka ga matsa lamba na hydrostatic, dogon lokacin zafi-resistant oxygen tsufa da aiki da gyare-gyare.
Menene bututun PP-R?
PP-R bututu kuma ana kiransa bututun polypropylene iri uku.Yana ɗaukar bazuwar copolymer polypropylene don fitar da shi cikin bututu, kuma a yi masa allura cikin bututu.Wani sabon nau'in samfurin bututun filastik ne wanda aka haɓaka kuma ana amfani dashi a Turai a farkon 1990s.PP-R ya bayyana a cikin ƙarshen 80's, ta amfani da tsarin copolymerization na gas don yin kusan 5% PE a cikin sarkar kwayoyin PP da kayyade kuma daidai da polymerized (random copolymerization) don zama sabon ƙarni na kayan bututun.Yana da kyakkyawar juriya mai tasiri da kuma aiki mai raɗaɗi na dogon lokaci.
Menene halayen bututun PP-R?PP-R bututu yana da wadannan manyan fasali:
1.marasa guba da tsafta.Kwayoyin albarkatun kasa na PP-R sune kawai carbon da hydrogen.Babu abubuwa masu cutarwa da masu guba.Suna da tsabta kuma abin dogara.Ba wai kawai ana amfani da su a cikin bututu mai zafi da sanyi ba, har ma ana amfani da su a cikin tsaftataccen tsarin ruwan sha.
2.Tsarin zafi da tanadin makamashi.Thermal watsin bututu PP-R ne 0.21w / mk, wanda shi ne kawai 1/200 na na karfe bututu.
3.mai kyau juriya zafi.Matsakaicin laushi mai laushi na PP-R tube shine 131.5 ° C. Matsakaicin zafin jiki na aiki zai iya kaiwa 95 ° C, wanda zai iya saduwa da buƙatun tsarin ruwan zafi a ginin samar da ruwa da ƙayyadaddun magudanar ruwa.
4. Rayuwa mai tsawo.A aiki rayuwa na PP-R bututu iya isa fiye da shekaru 50 a karkashin aiki zafin jiki na 70 ℃ da kuma aiki matsa lamba (PN) 1.OMPa;rayuwar sabis na al'ada zafin jiki (20 ℃) zai iya kai fiye da shekaru 100.
5.Easy shigarwa da haɗin dogara.PP-R yana da kyakkyawan aikin walda.Ana iya haɗa bututu da kayan aiki ta hanyar zafi-narke da walƙiya na lantarki, wanda ke da sauƙin shigarwa kuma abin dogara a cikin haɗin gwiwa.Ƙarfin sassan da aka haɗa ya fi ƙarfin bututun kansa.
6.Materials za a iya sake yin fa'ida.Sharar gida na PP-R tana tsaftacewa da niƙasa kuma ana sake yin fa'ida don samar da bututu da bututu.Adadin kayan da aka sake yin fa'ida bai wuce 10% na jimlar adadin ba, wanda baya shafar ingancin samfur.
Menene babban filin aikace-aikacen bututun PP-R?
1. Ginin tsarin sanyi da ruwan zafi, ciki har da tsarin dumama na tsakiya;
2.The tsarin dumama a cikin ginin, ciki har da bene, siding da tsarin dumama mai haske;
3.Tsaftataccen tsarin samar da ruwa don sha kai tsaye;
4.Central (tsakiyar) tsarin kula da iska;
5.Tsarin bututun masana'antu don jigilar ko fitar da kafofin watsa labarai na sinadarai.
