Viwanda vya kuhifadhi vinatumiwa kuhifadhi kemikali zilizosafishwa na asidi, alkooli, gesi, nk. Aina zake ni nyingi, kwa ujumla ni: chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma Kuhusu gharama ya kiwango cha kuhifadhi, sasa kwa kiwango cha kuhifadhi cha plastiki ni bora zaidi, kiwango cha kuhifadhi cha plastiki kinaweza kugawanywa kiwango cha kuhifadhi cha chuma cha chuma, mifumo miwili ya kiwango cha kuhifadhi cha plastiki kamili, ikiwa ni pamoja na aina nyingi za vertical, horizontal, usafirishaji, kuchanganya.

(1) mchakato wa usindikaji wa viwanda vya polyethylene:

Polyethylene (PE) horizontal kuhifadhi tank kwa polyethylene safi (linear low density polyethylene LLDPE, high density polyethylene HDPE) kama vifaa, kutumia mchakato roll plastics kuunda jumla.

(2) mchakato wa usindikaji wa chuma lining tank:

Chuma lining plastiki mtiririko tank pia inajulikana turtle lining tank (turtle lining - chuma, mtandao, plastiki tatu katika moja) ni kiini cha chuma plastiki mchanganyiko mfululizo wa bidhaa. Inatumia mchakato maalum wa kuunda roller. Ni kulehemu chuma mtandao (turtle) juu ya uso chuma mwili, kwa safi polyethylene (linear chini wiani polyethylene LLDPE, high wiani polyethylene HDPE) kama vifaa, kutumia mchakato roll plastics chuma sahani, chuma mtandao (turtle) na polyethylene kikaboni kuunganisha. Polyethylene imara kushikamana na uso wa chuma. Bidhaa ina faida ya hakuna welding, hakuna leakage, hakuna sumu, kupambana na kuzeeka, kupambana na athari, kupinga kutu, maisha mrefu, kufikia viwango vya usafi. Inafanya hasara ya nguvu ngumu ya tank ya plastiki kamili, kutokuwa na shinikizo, kutokuwa na joto tofauti. Bidhaa ya ndani ya uso ni gorofa, laini, imara, na kawaida chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma chuma Hivyo ni bora sana kuvunja kutu tank.
