Kubomi bemihla ngemihla, ukulinganiswa komlilo wezinto zokwakha kunokwahlulwa kumanqanaba A, B1, B2, kunye neB3. Iklasi A ayinakutsha.I-B1 ayinakutsha, i-B2 iyatsha, kwaye i-B3 iyatsha.

Okokuqala, kufuneka siqonde ukuba iithayile ze-synthetic resin azikho iplastiki. Njengommeli obalaseleyo wesizukulwana esitsha sezinto zokwakha iikhemikhali ezinobuhlobo kokusingqongileyo, iithayile ze-resin zokwenziwa,Kwinkqubo yokuvelisa, iithayile ze-resin zokwenziwa zenziwe ngobunjineli obuxhathisayo kwimozulu. I-resin ASA,Emva kovavanyo lomlilo, kwafumaniseka ukuba ikwinqanaba le-B1 eligatya idangatye.
Ukutshisa ikona ye-resin tile ngomlilo.Emva kokuba umthombo womlilo ushiye, Yintoni idangatye elicima ngokukhawuleza liyithayile ye-resin yokwenziwa kakuhle, kuba i-resin tile inomsebenzi ophawulekayo wokuba ayixhasi ukutsha kwaye ayivelisi umsi. 20, engeyiyo imveliso enokutsha;Ngokuchasene noko, ilangatye lithanda ukuba likhulu kwaye libe likhulu, kwaye likhupha ivumba elikhudlwana, kwaye kufuneka libe yi-resin ye-fake kunye neethayile ezingaphantsi. i-tile enenani elikhulu le-calcium carbonate enzima yongeza inani elikhulu le-plasticizer ukwenzela ukuba i-resin tile ibe neqondo elithile lokuguquguquka, kwaye esi songezo sinomsebenzi wokuxhasa ukutsha.Ngale ndlela, i-resin tile ayihlanganisi nje kuphela. iimfuno zokhuseleko lomlilo, kodwa akanakuxhathisa ukwaluphala kunye nobomi obufutshane.

Iithayile ze-synthetic resin zineenzuzo ezibalaseleyo zokusebenza malunga nokhuseleko lomlilo, ukonga amandla kunye nokhuseleko lokusingqongileyo. Isetyenziswe ngokubanzi ekwakhiweni kwezakhiwo zabucala, izakhiwo zoluntu, izakhiwo zakudala, njl. imakethi yezinto zokwakha.
