Yintoni umahluko phakathi kwe-ACR-401 kunye nezinye izongezo ze-PVC?

I-ACR-401, njengesixhobo sokuncedisa ukucubungula i-PVC, inomahluko ophambili kwindawo yokusebenza, ulwakhiwo lwemolekyuli, kunye neemeko zokusetyenziswa. Uthelekiso oluthile lulandelayo:

1. Umahluko kwindawo yokusebenza

I-ACR-401: Yenzelwe ngokukodwa ukuqinisa ukunyibilika, yenza iindawo zokudibanisa ezibonakalayo ngesakhiwo se-core-shell (i-core core/i-soft shell), yonyusa amandla okunyibilika ngama-300%, ngakumbi efanelekileyo kwiimveliso ze-foam (ezifana neebhodi ze-foam).

I-ACR-201: Igxile ekukhuthazeni ukwenziwa kweplastiki, ukunciphisa ixesha lokunyibilika kwePVC ngemizuzwana engama-40-60, ifanelekile kwiimeko zokucubungula ezisisiseko ezifana nemibhobho eqinileyo kunye neeprofayili.

I-ACR-530: Ukulinganisela ukuthambisa kunye nokufakelwa kweplastiki, ukudibanisa amaqela e-stearic acid kunokunciphisa i-torque nge-15-20% kwaye kusombulule ingxaki yokuchacha kwentloko yesikhunta.

2. Iimpawu zesakhiwo se-molecular

I-ACR-401: Ukwamkela isakhiwo se-core-shell se-methyl methacrylate (MMA) kunye ne-acrylic ester copolymer, kunye ne-hard core enika amanqaku okudibanisa kunye ne-soft shell ephucula ukunyibilika.

Izongezo ze-MBS: kunye ne-styrene butadiene njengesiseko kunye ne-methyl methacrylate njengeqokobhe, egxile ekukhanyeni nasekuchaseni impembelelo, kodwa kunye nokumelana nemozulu okubi.

Izongezo zohlobo lweCPE: Ulwakhiwo lwe-polyethylene ekhlorini, oluphucula ukuqina ngokufaka iplastiki, kodwa lunokunciphisa lula amandla okunyibilika.

3. Umahluko kwiiparameter zobugcisa

Ubukhulu be-intrinsic viscosity: I-ACR-401 yi-2.0-5.0, iphezulu kune-ACR-201 (2.0-3.0), ebonisa iimpawu zayo eziphezulu zobunzima be-molecular.

Isixa esongeziweyo: I-ACR-401 kwiimveliso zefoam ifuna i-1.5-3phr, ngelixa i-ACR-201 iyonke ifuna i-0.5-2phr kuphela.
