Qiniseka ukuba uthi ezintathu, kufuneka: PPR, PVC, PE
1. Imibhobho yeplastiki esetyenziswa ngokuqhelekileyo yile: PPR (polypropylene), PVC (polyvinyl chloride), PB (polybutene), PE-RT (i-polyethylene enganyangeki ukushisa), PE (polyethylene) \HDPE (i-polyethylene eyomeleziweyo) ethylene), njl.
Okwesibini, ubukhulu bemibhobho yeplastiki ngokuqhelekileyo ibonakaliswe ngokubhekiselele kububanzi bangaphandle.Njenge ityhubhu yePPR: De63
3. Ubomi benkonzo yeMF BALL VALVE X9011igqitywe ngokwe-GB/T18252-2000 "Inkqubo yokubhobhoza iplastiki - Ukumiselwa kwamandla exesha elide le-hydrostatic yemibhobho ye-thermoplastic nge-extrapolation".Le yindlela yokwenza i-statistically extrapolating kunye nokuqikelela iimpawu zamandla exesha elide lezinto ze-thermoplastic okanye amanqaku avela kwiziphumo zovavanyo lwamandla e-hydrostatic emibhobho.*Uninzi lwaba bangasentla basebenzisa le ndlela ukubala, phantsi kwemeko yobushushu obuyi-20 ℃, umbhobho weplastiki udla ngokuphila iminyaka engama-50.
Okwesine, izixhobo zokubumba kwimibhobho yeplastiki ngumatshini wokubumba umjovo, owenziwe kwimibhobho ngomatshini wokubumba.
5. Ngokuqhelekileyo kukho iindlela ezimbini zokudibanisa iipayipi zeplastiki: ukunyibilika okushushu kunye neglue.
6. Imigangatho yemibhobho yeplastiki ikakhulu ibandakanya:
1. PPR (ipolypropylene): GB/T18742.1, GB/T18742.2, GB/T18742.3
2. I-PVC (i-polyvinyl chloride): GB/T10002.1-2006, GB/T10002.2-2003
3. PE (ipolyethylene): GB15558, GB/T13663
4. I-HDPE (iPolyethylene eNxinaniswayo eNxinaniswayo): GB/T19472.2-2004
Imibhobho yePlastiki ikakhulu ibandakanya iPPR (ipolypropylene), iPVC (i-polyvinyl chloride), i-PB (i-polybutene), i-PE-RT (i-polyethylene ekwazi ukumelana nobushushu), i-PE (i-polyethylene), i-HDPE (i-polyethylene ephuculweyo ephezulu), njl. i-polypropylene (PP), i-polyvinyl chloride (PVC), i-polyethylene (PE) kunye nezinye iipolymers.
Umbhobho wePlastiki ligama eliqhelekileyo lemibhobho eyenziwe ngezinto zeplastiki.Imibhobho yeplastiki ineempawu zobunzima bokukhanya, ucoceko kunye nokhuseleko, ukumelana nokuhamba kwamanzi amancinci, ukonga amandla, ukugcinwa kwesinyithi, ukuphuculwa kwendawo yokuhlala, ubomi benkonzo ende, ukhuseleko kunye nokulula, njl.Kwiminyaka eyi-10 edlulileyo, eqhutywa luphuhliso olukhulu lwelizwe lam, imibhobho yeplastiki yelizwe lam ifumene uphuhliso olukhawulezayo phantsi kwemvelaphi yophuhliso olukhulu lwezinto zokwakha iikhemikhali.Kwi-2010, imveliso yesizwe yeepayipi zeplastiki idlule iitoni ezizigidi ezisi-8, apho i-Guangdong, iZhejiang kunye ne-Shandong zibalelwa kwi-42% yemveliso.Imibhobho yeplastiki ineenzuzo ezininzi kwimibhobho yentsimbi yemveli kunye nemibhobho yekhonkrithi kwiindawo ezininzi, ngoko ke isetyenziswe ngokubanzi kwiindawo ezininzi.
