U hubso inaad tidhaahdo saddex, waa inay noqotaa: PPR, PVC, PE
1. Tuubooyinka caaga ah ee sida caadiga ah loo isticmaalo waa: PPR (polypropylene), PVC (polyvinyl chloride), PB (polybutene), PE-RT (polyethylene kulaylka u adkaysta), PE (polyethylene) \ HDPE (la xoojiyay cufnaanta sare ee polyetylen) ethylene). iwm.
Marka labaad, cabbirka tuubooyinka caagga ah ayaa guud ahaan lagu muujiyaa dhexroorka dibadda.Sida tuubada PPR: De63
3. Nolosha adeegga eeMF BALL VALVE X9011waxaa lagu go'aamiyaa iyadoo loo eegayo GB/T18252-2000 "Nidaamka tuubooyinka caaga ah - Go'aaminta xoogga muddada dheer ee hydrostatic tuubooyinka thermoplastic by extrapolation".Tani waa hab xisaabeed ka baxsan iyo saadaalinta sifooyinka xoogga muddada-dheer ee qalabka kulaylaha ama maqaallada laga soo bilaabo natiijooyinka tijaabooyinka xoogga hydrostatic ee tuubooyinka.Inta badan kuwa kor ku xusan waxay isticmaalaan habkan si ay u xisaabiyaan, heerkulka heerkulka 20 ℃, tuubada caaga ah guud ahaan waxay leedahay cimri dherer ah 50 sano.
Midda afraad, qalabka wax lagu beddelo ee tuubooyinka caagga ah waa mishiinka wax-qaabeeya ee irbado, kaas oo lagu dhejiyo tuubooyinka mishiinka wax-qaabaynta.
5. Guud ahaan waxaa jira laba siyaabood oo lagu xiro tubooyinka caagga ah: dhalaal kulul iyo koollo.
6. Heerarka tuubooyinka balaastikada ah inta badan waxaa ka mid ah:
1. PPR (polypropylene): GB/T18742.1, GB/T18742.2, GB/T18742.3
2. PVC (polyvinyl chloride): GB/T10002.1-2006, GB/T10002.2-2003
3. PE (polyetylen): GB15558, GB/T13663
4. HDPE (La xoojiyay cufnaanta Sare ee Polyethylene): GB/T19472.2-2004
Tuubooyinka caaga ah inta badan waxaa ka mid ah PPR (polypropylene), PVC (polyvinyl chloride), PB (polybutene), PE-RT (polyetylen kulaylka u adkaysta), PE (polyetylen), HDPE (kor u qaaday cufnaanta sare polyetylen), iwm. polypropylene (PP), polyvinyl chloride (PVC), polyetylen (PE) iyo polymers kale.
Dhuumaha caagga ah waa erey guud oo loogu talagalay tubooyinka ka samaysan alaabta caagga ah.Tuubooyinka caaga ah waxay leeyihiin sifooyinka miisaanka fudud, fayadhowrka iyo badbaadada, caabbinta socodka biyaha yar, badbaadinta tamarta, badbaadinta birta, hagaajinta deegaanka nolosha, nolosha dheer ee adeegga, badbaadada iyo raaxada, iwm, waxaana doorbidaya bulshada injineernimada dhuumaha.10-kii sano ee la soo dhaafay, oo uu horseeday horumarka dhaqaale ee dalkeyga, tuubooyinka caagga ah ee dalkaygu waxay la kulmeen horumar degdeg ah oo ka hooseeya horumarka weyn ee qalabka dhismaha ee kiimikada.Sannadkii 2010, wax soo saarka qaranka ee tuubooyinka balaastikada ah ayaa dhaaftay 8 milyan oo tan, kuwaas oo Guangdong, Zhejiang iyo Shandong ay ka ahaayeen 42% wax soo saarka.Tuubooyinka caagga ah ayaa faa'iidooyin badan ka leh tuubooyinka birta ee dhaqameed iyo tuubooyinka shubka ah ee meelo badan, sidaas darteed si ballaaran ayaa loo isticmaali jiray meelo badan.
