Umgaqo wokusebenza komlawuli we-PVC foaming ufezekiswa ikakhulu ngokulawula iipropati zomzimba nezekhemikhali ze-PVC melt. Imisebenzi ethile yile ilandelayo:
1. Khuthaza ukwenziwa kweplastiki kunye nokunyibilikisa okufanayo
I-long molecular chain of foaming regulator (ACR) ikhawulezisa ukwenziwa kweplastiki kwezinto ngokubhinca i-PVC molecular chain, inciphisa ubushushu bokucubungula, kwaye yenze isakhiwo senethiwekhi yejeli. Le nkqubo ayikhawulezisi nje kuphela isantya sokunyibilika, kodwa ikwakhuthaza ukusasazeka okufanayo kwezongezo kunye nee-agents ze-foaming, inciphisa iziphene zangaphakathi kwi-melt.
2. Yomeleza amandla kunye nokuqina kwe-melt
Ulwakhiwo lwenethiwekhi olunemilinganiselo emithathu olwenziwe kukuxinana kweetsheyini zemolekyuli luphucula kakhulu amandla okunyibilika, nto leyo eyenza ukuba ikwazi ukugquma igesi ngempumelelo kwaye imelane nokuhlangana kweeseli ngexesha lenkqubo yokufutha. Kwangaxeshanye, inika ukunyibilika ukuthamba, ivumela iimbobo ukuba zande kwaye zinciphe ngokulinganayo, igcina isakhiwo seseli esivaliweyo.
3. Ukulawula ibhalansi ye-viscoelasticity ye-melt
Umlawuli ulungisa i-viscoelasticity ye-PVC melt, andise ixesha lokubila, aze afanise izinga lokubola kwe-agent ye-foam kunye nezinga lokusasazeka kwegesi. Lo mthetho unganciphisa izinga lokugqabhuka kweqamza (njengoko kubonisiwe kwidatha yovavanyo, izinga lokugqabhuka liye lehla ukusuka kwi-25% ukuya kwi-8%) kwaye liphucule ukufana kokusasazwa kwegesi kwi-melt.
4. Lungiselela ulwakhiwo lwembobo kunye nozinzo
Amandla aphuculweyo okunyibilika kunye nokuthamba kunokuthintela ukuqhekeka kwe-extrusion yee-pores ezikufutshane, kwenze isakhiwo seseli esincinci nesifanayo esivaliweyo. Ii-regulators ezinobunzima obuphezulu beemolekyuli, ezifana ne-HL530, zinokunciphisa ngakumbi uxinano lwemveliso, ngelixa zilawula ukutyibilika kwekhonkco leemolekyuli ukuthintela ukudilika kwee-pores okubangelwa kukuphumla okugqithisileyo.
5. Phucula umphezulu kunye neempawu zoomatshini zemveliso
Ukuphuculwa kokulingana kokunyibilika kunciphisa iimpawu zokuhamba komphezulu kunye neziphene zokuncipha, kwaye kuphucula ukucoceka komphezulu. Ukonyuka kwamandla okunyibilika ngokungathanga ngqo kuphucula ukumelana nempembelelo kunye nokuzinza kobukhulu bemveliso.
Ngamafutshane, umgaqo wayo wokusebenza ngokuyintloko kukufezekisa ulawulo oluchanekileyo lwamandla okunyibilika, i-viscoelasticity, kunye ne-foaming kinetics ngokusebenzisa iziphumo zokujika ngokwasemzimbeni kunye ne-chemical synergistic, ngaloo ndlela kulungelelaniswa uxinano lweeseli, ukuthembeka kwesakhiwo, kunye nokusebenza kakuhle kokucubungula.
