PPR quvurlarining afzalliklari qanday?

Binolarni bezash va suv ta'minoti va drenaj tizimlarida, quvur materiallarini tanlash loyihaning sifati va yashash xavfsizligiga bevosita ta'sir qiladi. Dastlabki metall quvurdan hozirgi plastik quvurgacha, bozor tanlovi tobora xilma-xil bo'lib bormoqda. Ular orasida, PPR trubkasi o'zining noyob ishlashi bilan asta-sekin asosiy oqimga aylandi. Ushbu maqolada, PPR quvurining asosiy afzalliklarini tahlil qilamiz, va PVX bilan, metall quvur, alyuminiy kompozit quvur va boshqa materiallarni taqqoslash, ilmiy qarorlar qabul qilishingizga yordam beradi.

Birinchidan, PPR trubkasi: material xususiyatlari va jarayon innovatsiyasi

PPR (tasodifiy kopolimer polipropilen) oziq-ovqat polimer xom ashyosidan foydalangan holda quvur, yuqori haroratli ekstrusion kalıplama orqali, quyidagi asosiy afzalliklarga ega:  

1. Harorat va bosimga qarshilik: ish harorati oralig'i -20 ℃ gacha 95 ℃, gacha qisqa muddatli yuqori harorat qarshiligi 110 ℃, 2,5MPa dan ortiq bosimga bardosh bera oladi, issiq va sovuq suv dual tizimining ehtiyojlarini qondirish uchun.

2. kimyoviy inertsiya: suvdagi xlor ionlariga qarshilik ko'rsatish, kislotali va gidroksidi korroziya, an'anaviy metall quvurlar zang va ifloslanish muammolaridan qochish.

3. issiq termoyadroviy ulanish: quvur qismlarini birlashtirilgan payvandlash, interfeys oqishini bartaraf etish uchun, ko'proq oshirish uchun tishli ulanishlar ko'ra o'lchangan muhrlanish 60%.

4. Uzoq umr: Laboratoriya tezlashtirilgan qarish testlari shuni ko'rsatadiki, PPR trubkasi xona haroratida xizmat qilish muddati ko'proqqa yetishi mumkin 50 yillar.

Ikkinchi, yonma-yon taqqoslash: beshta asosiy quvur ishlashi testi

1. PPR quvurlari PVX quvurlarga qarshi

Moddiy farqlar: PVX (polivinilxlorid) tarkibida xlor elementlari mavjud, yuqori harorat iz vodorod xlorid gazini chiqarishi mumkin; PPR toza polipropilendir, yuqori salomatlik darajasi.  

Harorat ko'rsatkichi: PVX quvur uzoq muddatli foydalanish harorati ≤ 45 ℃, faqat sovuq suv tizimi uchun; PPR quvurini tashish uchun barqarorlashtirish mumkin 80 ℃ issiq suv.  

Ta'sir kuchi: PPR quvurining past haroratli zarba qarshiligi PVXdan yaxshiroqdir, -10 ℃ atrof-muhitga ta'sir qilish sinovi buzilmasdan.  

Xulosa: Drenaj tizimi uchun PVX quvur mos keladi, PPR trubkasi esa issiq va sovuq suv ta'minoti uchun yaxshiroq echimdir.

2. PPR quvurlari va metall quvurlar (mis / zanglamaydigan po'lat)

Gigienani taqqoslash: metall quvurlar elektrokimyoviy korroziyaga moyil, eski mahallalarda ko'pincha "qizil suv" hodisasi paydo bo'ladi; Metall ionlarining cho'kmasini butunlay yo'q qilish uchun PPR trubkasi.  

O'rnatish narxi: mis quvurlari materialining narxi PPR 4-6 marta, va professional payvandlash uskunalariga bo'lgan ehtiyoj; PPR issiqlik termoyadroviy mashinasini ishlatish oson, ning mehnat xarajatlarini tejash 40%.  

Issiqlik izolyatsiyasi ko'rsatkichlari: PPR issiqlik o'tkazuvchanligi 0,24W / m-K, faqat 1/300 mis quvuridan, issiqlik yo'qotilishini kamaytirish.  

Case: besh yulduzli mehmonxona issiq suv tizimini ta'mirlash, energiyani tejash uchun asl mis quvur tizimidan ko'ra PPR quvuridan foydalanish 18%.

3. PPR trubkasi alyuminiy-plastmassa kompozit quvurga qarshi

Strukturaviy farqlar: aluminum-plastic pipe five-layer composite structure of the risk of delamination, burst pressure test in the PPR pipe pressure resistance is 23% higher.  

Repairability: Aluminum-plastic pipe needs to be replaced in its entirety, while PPR pipe can be repaired conveniently by heat fusion.

Iqtisodiyot: the same specification pipe, aluminum-plastic composite pipe price is 30-50% higher than PPR.  

Data: Third-party testing shows that aluminum-plastic pipe delamination occurs after 2,000 thermal cycles, while PPR pipe through 5,000 tests without anomalies.

4. PPR pipe vs PE pipe

Difference in crystallinity: PE (polietilen) material has higher crystallinity, better low-temperature toughness but limited temperature resistance (PE-RT long-term use temperature ≤ 60 ℃).  

Reliability of connection: PE pipe is connected by electrofusion, which requires high construction precision; the success rate of PPR heat fusion joints can reach 99.8%.  

Application scenario: PE pipe is more suitable for floor heating system, while PPR pipe is better in comprehensive performance.

Decision-making guide for application scenarios

Uchinchi, the three golden guidelines for the purchase of PPR pipe

1. Raw material certification: Recognize the “PP-R 100” raw material logo, reject the inferior pipe mixed with recycled materials. 2.

2. Wall thickness standard: S 2.5 series (wall thickness of 3.5 mm) to meet the family use, high-rise buildings are recommended to use S 2.0 series. 3.

3. brand guarantee: choose through the GB/T 18742 certification of the regular manufacturers, warranty commitments should include 50 years of quality assurance.

Promoted by the concept of sustainable development, PPR pipe with its excellent performance, economic and environmental advantages, is leading the pipeline industry change. Whether it’s for home renovation or municipal projects, choosing quality PPR pipes means choosing peace of mind and long-lasting value.
