Hubso inaad dhahdo seddex, waa inay noqotaa: PPR, PVC, PE
1. Tuubooyinka caagga ah ee caadiga ah ee loo isticmaalo waa: pvc (polyvinyl chloride), pb (pbtvinyl), polybutene), polybylne), polybylne), polybylne), polybylne), polybylne), polybylne), polybylne), polybylne), polybylne), polybylne), polybylne), polybylne), polybylne), polybylne), polybylne), polybylne), polybylne), polyethylne), polyethylen), polyethylen) \ hdpetyl) \ hdpetyl (ethylen), iwm.
Midda labaad, cabirka tuubooyinka caaga ah ayaa guud ahaan lagu muujiyaa iyadoo la raacayo dhexroor ka baxsan. Sida tuubada PPR: de63
3. Nolosha adeegga eeMf kubbadda valve x9011Waxaa lagu go'aamiyaa sida ku xusan GB / T18252-200 "Nidaamka tuubooyinka caagga ah - Go'aaminta xoogga muddada-dheer ee hawada sare ee tuubooyinka thermoplastic-ka ah ee loo soo celiyo". Tani waa hab tilmaanta tirakoobka ah oo la soo saaray oo saadaalinaya guryaha muddada-dheer ee xoogga muddada-dheer ee walxaha heerkulka ah ama qodobbada laga soo qaado natiijooyinka baaritaanka tuubooyinka xoogga ee burooyinka. * Inta badan adeegsiga kor ku xusan qaabkan si loo xisaabiyo, sida ku xusan xaaladda heerkulka ee 20 ℃, biinanka caagga ah guud ahaan waxay leeyihiin nolol 50 sano ah.
Afaraad, qalabka qaababka ee tuubooyinka tuuladu waa mashiinka caagagga ah ee mudista ah, kaas oo loo yaqaan tuubooyinka mashiinka caqabadda duritaanka.
5. Guud ahaan waxaa jira laba dariiqo oo lagu xirayo tuubooyinka caagga ah: kulul kulul iyo koolada.
6. Heerarka tuubooyinka caaga ah badiyaa waxaa ka mid ah:
1. Ppr (polypropylene): GB / T18742.1, GB / T187442.2, GB / T187742.3
2. PVC (pvc (polyvinyl chloride): GB / T10002.1006, GB / T10002.2-2-22003
3. PE (polyetylen): GB15558, GB / T13663
4. Hdpe (polnency polyetylen): GB / T19472.2-2004
Plastic pipes mainly include PPR (polypropylene), PVC (polyvinyl chloride), PB (polybutene), PE-RT (heat-resistant polyethylene), PE (polyethylene), HDPE (enhanced high-density polyethylene), etc. The materials used are Polypropylene (pp), polyvinyl chloride (PVC), polyetylne (PE) iyo pemoodka kale.
Tuubbada balaastigga ah waa erey guud oo loogu talagalay tuubooyinka laga sameeyay agab caag ah. Tuubbooyinka caagga ah waxay leeyihiin astaamaha culeyska khafiifka ah, fayadhowrka iyo badbaadada, caabbinta biyaha yar, badbaadinta birta, nolosha adeegga, nabadgelyada, iyo ku habboonaanta, waxaana ku habboon bulshada dipline-ka bulshada. 10-kii sano ee la soo dhaafay, oo ay wateen horumarinta macroeconomic ee dalkayga, tuubooyinka caagga ah ee dalkayga ayaa khibrad u leh horumarin deg deg ah iyada oo la raacayo horumarka weyn ee qalabka dhismaha kiimikada. Sanadkii 2010, wax soo saarka qaranka ee tuubooyinka caaga ah ayaa dhaaftay 8 milyan oo tan, kaas oo reer Guangdong ah, Zhejiang iyo Shandong ay tiriyeen 42% wax soo saarka. Tuubbooyinka caagga ah waxay leeyihiin faa iidooyin badan oo ka dhaca tuubooyinka biraha dhaqameedyada iyo tuubooyinka la taaban karo ee beero badan, sidaa darteed si ballaaran loogu adeegsaday meelo badan.
