Yintoni iMathiriyeli yeNaliti elahlayo

I-tube yenaliti yiPP, i-k4912 yinto ekhethekileyo yonyango lwezonyango, kwaye yenziwe nguYanshan Petrochemical. Andazi ngenene ibhegi yokugalela. Imodeli yoncedo inxulumene nezinto ezisetyenziswayo zonyango eziqhelekileyo ezisetyenziswa ikakhulu kufakelo lwemithambo kunye nokuvalwa inzala ukuseka umjelo phakathi kwemithambo kunye neyeza elingamanzi. Ngokuqhelekileyo yenziwe ngenaliti efakwa emithanjeni, ikepusi ekhuselayo, ithumbu lokufakela, isihluzo samayeza angamalwelo, isilawuli sesantya sokuqukuqela, imbiza yokuthontsiza, isixhobo sokugqobhoza isivalo sebhotile, umbhobho wokungenisa umoya kunye nesihluzo somoya. Iiseti zokunyuswa zemveli zenziwe ngePVC. Ukusebenza okuphezulu kwepololefin thermoplastic elastomer (TPE) ithathwa njengeyona nto ikhuselekileyo nephezulu yokusebenza imathiriyeli yokwenza iiseti zokugalela ezilahlwayo. Ngoku kukho into engenanto i-DEHP kwaye ikhuthazwa kulo lonke ilizwe. Ngaphantsi kwesenzo soxinzelelo lwe-atmospheric, ulwelo olukwibhotile luqukuqela ukuya kwi-emele yokuthontsiza ecaleni kombhobho obhityileyo wokufakela. Xa uxinezeleko lwekholamu yamanzi kwi-emele yokuthontsiza lukhulu kunoxinzelelo lwe-venous, ulwelo olusebhotileni luphumela kumthambo ecaleni kombhobho.
