Wazi kangakanani malunga nezixhobo zokusetyenzwa kwe-ACR?

I-PVC ibuthathaka kakhulu kubushushu.Xa iqondo lobushushu lifikelela kuma-90 ℃, intshukumo encinci yokubola kwe-thermal iqala.Xa ubushushu bunyuka ukuya kwi-120 ℃, ukusabela kokubola kuyaqina.Emva kokufudumeza nge-150 ℃ imizuzu eyi-10, i-resin ye-PVC itshintsha ngokuthe ngcembe ukusuka kumbala wayo omhlophe wokuqala ukuya kumthubi, obomvu, omdaka, kunye nomnyama.Ubushushu bokusebenza kwePVC ukufikelela kwimo yokuqukuqela kwe-viscous kufuneka ibephezulu kunobu bushushu.Ngoko ke, ukwenzela ukuba i-PVC isebenze, iintlobo zezongezo kunye nezihluzi ezifana ne-plasticizers, stabilizers, lubricants, njl.Izixhobo zokusetyenzwa kwe-ACR yenye yezinto ezibalulekileyo zokusetyenzwa.Iphuma kudidi lwe-acrylic processing aids kwaye i-copolymer ye-methacrylate kunye ne-acrylic ester.Izixhobo zokulungisa i-ACR zikhuthaza ukunyibilika kweenkqubo zokucubungula i-PVC, ukuphucula iimpawu ze-rheological zokunyibilika, kwaye iindawo ezingahambelaniyo kunye ne-PVC zinokufudukela ngaphandle kwenkqubo ye-resin etyhidiweyo, ngaloo ndlela iphucula ukusebenza kwayo kokudiliza ngaphandle kokunyusa ukusetyenziswa kwamandla kwezixhobo zokusebenza.Ingabonwa ukuba izixhobo zokulungisa i-ACR zidlala indima ebalulekileyo kwiinkqubo zePVC.

Izinto ezilungileyo zokusebenzisa izixhobo zokulungisa i-ACR:

1. Inokuhambelana kakuhle kunye ne-PVC resin, kulula ukuyichitha kwi-resin ye-PVC, kwaye kulula ukuyisebenzisa.

2. Ineplastiki yangaphakathi kwaye ingasetyenziselwa kwizinto eziphathekayo zezicathulo, ucingo kunye nezixhobo zekhebula, kunye nezinto ezithambileyo ezicacileyo zokunciphisa inani leplastiki esetyenzisiweyo kunye nokusombulula ingxaki yokufuduka komphezulu weplastiki.

3. Inokuphucula kakhulu ukuguquguquka okuphantsi kobushushu kunye namandla empembelelo yemveliso.

4. Ukuphucula ngokuphawulekayo ukukhanya komphezulu wemveliso, ngaphezu kwe-ACR.

5. Ukuzinza kakuhle kwe-thermal kunye nokumelana nemozulu.

6. Nciphisa i-viscosity enyibilikayo, unciphise ixesha leplastiki, kunye nokwandisa isivuno seyunithi.Ukuphucula amandla empembelelo kunye nokuguquguquka okuphantsi kobushushu bemveliso.

Ukutshintsha i-ACR ngobungakanani obulinganayo kunokunciphisa ukusetyenziswa kwe-lubricant okanye ukonyusa ukusetyenziswa kwesihluzi ngelixa ugcina iipropathi zezinto eziphathekayo, ukuvula iindlela ezintsha zokuphucula umgangatho wemveliso kunye nokunciphisa iindleko.
