Nantoni na enokuphucula iipropati zokuqala ze-resin ngemiphumo yomzimba, yoomatshini neyekhemikhali inokubizwa ngokubaukuguqulwa kweplastikiIntsingiselo yokuguqulwa kweplastiki ibanzi kakhulu. Ngexesha lenkqubo yokuguqulwa, utshintsho lwendalo nolweekhemikhali lunokufezekisa oko.
Iindlela ezisetyenziswa kakhulu zokuguqula iplastiki zezi zilandelayo:
1. Yongeza izinto eziguquliweyo
a. Yongeza izinto ezingaphiliyo okanye ezingaphiliyo ze-molecule encinci
Izongezo ezingezizo zendalo ezifana nezizalisi, ii-reinforcement agents, ii-flame retardants, ii-colorants kunye nee-nucleating agents, njl.
Izongezo zendalo eziquka iiplastiki, iziqinisi ze-organotin, ii-antioxidants kunye nezithinteli zomlilo zendalo, izongezo zokubola, njl. Umzekelo, iTopfeel yongeza izongezo ezibolayo kwezinye iibhotile zePET ukukhawulezisa izinga lokubola kunye nokubola kweeplastiki.
b. Ukongeza izinto zepolymer
2. Ukuguqulwa kwesimo kunye nolwakhiwo
Le ndlela ijolise kakhulu ekutshintsheni imo ye-resin kunye nolwakhiwo lweplastiki ngokwayo. Indlela eqhelekileyo kukutshintsha imeko yekristale yeplastiki, ukudibanisa, ukuhlanganisa, ukuhlanganisa, ukuhlanganisa njalo njalo. Umzekelo, i-styrene-butadiene graft copolymer iphucula impembelelo yezinto ze-PS. I-PS isetyenziswa kakhulu kwiindawo zokugcina iiTV, izixhobo zombane, izibambi zeepeni ze-ballpoint, izibani zezibane kunye neefriji, njl.
3. Ukuguqulwa kwekhompawundi
Ukuguqulwa kweeplastiki ngendlela edibeneyo yindlela apho iileya ezimbini okanye ngaphezulu zeefilimu, amaphepha kunye nezinye izinto zidityaniswe kunye nge-adhesive okanye i-hot melt ukuze kwenziwe ifilimu eneeleya ezininzi, ishiti kunye nezinye izinto. Kwishishini lokupakisha izinto zokuhombisa, iityhubhu zeplastiki zokuhombisa kunyeiityhubhu ezidityanisiweyo ze-aluminium-plastikizisetyenziswa kule meko.
4. Ukuguqulwa komphezulu
Injongo yokuguqulwa komphezulu weplastiki inokwahlulwahlulwa ibe ziindidi ezimbini: enye kukuguqulwa okuthe ngqo, enye kukuguqulwa okuthe ngqo.
a. Utshintsho lomphezulu weplastiki olusetyenziswa ngqo oluquka ukukhazimla komphezulu, ubulukhuni bomphezulu, ukumelana nokuguguleka komphezulu kunye nokungqubana, ukulwa nokwaluphala komphezulu, ukuthintela ilangatye lomphezulu, ukuqhuba komgangatho kunye nomqobo womphezulu, njl.
b. Ukusetyenziswa ngokungathanga ngqo kokuguqulwa komphezulu weplastiki kuquka ukuguqulwa kokuphucula uxinzelelo lomphezulu weplastiki ngokuphucula ukunamathela, ukuprintwa kunye nokulamination kweplastiki. Xa sijonga imihombiso ye-electroplating kwiplastiki njengomzekelo, kuphela ukuqina kwe-coating ye-ABS okunokuhlangabezana neemfuno zeplastiki ngaphandle kokulungiswa komphezulu; Ingakumbi kwiiplastiki ze-polyolefin, ukuqina kwe-coating kuphantsi kakhulu. Ukuguqulwa komphezulu kufuneka kwenziwe ukuphucula ukuqina kokudibanisa kunye ne-coating ngaphambi kokufakelwa kwe-electroplating.
Oku kulandelayo yiseti yezikhongozeli zesilivere ezikhazimlayo ngokupheleleyo: Udonga oluphindwe kabini 30g 50gijagi yekhrimu, 30ml icinezelweibhotile yedrophakunye ne-50mlibhotile yeloshini.
