Injongo yomlawuli we-PVC foaming: Ukongeza kuzo zonke iimpawu ezisisiseko zezixhobo zokulungisa i-PVC, izixhobo zokulawula i-foaming zinobunzima obuphezulu be-molecular kunezixhobo zokulungisa ezisetyenziswa ngokubanzi, amandla aphezulu okunyibilika, kwaye zinokunika iimveliso ulwakhiwo lweseli olufanayo kunye noxinano oluphantsi. Ukuphucula uxinzelelo kunye ne-torque ye-PVC melt, ukuze kwandiswe ngokufanelekileyo ukuhambelana kunye nokuhambelana kwe-PVC melt, kuthintelwe ukudibana kwamaqamza, kwaye kufumaneke iimveliso ezifanayo ze-foaming.
Iingenelo zabalawuli be-PVC foaming:
1. Izixhobo zokucubungula i-ACR zinokukhuthaza ukunyibilika kwe-PVC, ziphucule ukugqitywa komphezulu, ziphucule ukuthamba kwe-melt, kwaye ziphucule ubude kunye namandla e-melt.
2. Kuluncedo ukugquma amaqamza nokuthintela ukudilika kweeseli. Ubunzima bemolekyuli kunye nomthamo we-foam regulator zinempembelelo enkulu kuxinano lwephepha le-foam: ngokwanda kobunzima bemolekyuli, amandla okunyibilika e-PVC ayanda, kwaye uxinano lwephepha le-foam lunokwenziwa lube sezantsi, kwaye ukwanda komthamo we-regulator kunempembelelo efanayo. Kodwa esi siphumo asinalo ulwalamano oluthe ngqo. Qhubeka unyusa ubunzima bemolekyuli okanye unyuse umthamo, isiphumo sokunciphisa uxinano asibonakali kakhulu, kwaye uxinano luya kuhlala luhleli.
3. Iimveliso ze-molecular weight eziphezulu kakhulu kunye ne-melt strength endow ezinamandla kakhulu ezinobunzima obuphantsi kunye nesakhiwo seeseli esifanayo, ezifanelekileyo ngakumbi kwiimveliso zebhodi ezityebileyo ezine-foam zePVC.
4. Nika imveliso isakhiwo seseli esifanayo, ubunzima beemolekyuli eziphezulu kunye namandla aphezulu okunyibilika, uxinano oluphantsi lwemveliso, kunye nokusebenza kakuhle kokucubungula.
5. Ubuchule obuhle bokwenza iplastiki ibe yiplastiki, ukunyibilika okugqwesileyo kokunyibilika, kunye nokuhambelana okuhle neemveliso zePVC, okwenza imveliso ibe nobukhulu obuzinzileyo.
6. Ukusebenza kakuhle kweplastiki, okunika imveliso ukusebenza kakuhle kokucubungula kunye nokukhazimla okugqwesileyo komphezulu.
Amanyathelo okusebenzisa abalawuli be-PVC foaming:
Xa usebenzisa abalawuli be-PVC foaming, kufuneka kuqwalaselwe iimveliso ze-PVC ezinamaqondo ahlukeneyo e-polymerization kwaye kufuneka kukhethwe abalawuli be-foaming abahlukeneyo. Iimveliso ze-foam zeplastiki ziquka: ibhodi ye-foam, ibhodi etyebileyo ye-foam, ibhodi ye-foam ebhityileyo ye-foam, ibhodi ye-foam yeplastiki yomthi, ibhodi ye-foam yeplastiki ekhokelayo, njalo njalo. Khetha abalawuli be-foaming abahlukeneyo. Ngenxa yokuba izixhobo ze-PVC foaming zikwayi-acrylic ester substances ezineempawu zoncedo lokucubungula, kufuneka kuqwalaselwe nokulinganisela kokuthambisa kwangaphakathi nangaphandle kwefomyula xa usebenzisa.
