Ucwaningo mayelana nokululama nokusebenzisa kabusha ubuchwepheshe be-CPE kanye ne-acrylate processing AIDS

Ngokuthuthuka okusheshayo kwemboni yepulasitiki, i-chlorinated polyethylene (CPE) ne-acrylic Icubungula Izithasiselo (ezifana ne-ACR) ziyizinto ezibalulekile eziguquliwe ze-polymer, futhi ubuchwepheshe bokugaywa kabusha nokusetshenziswa kabusha kwemfucuza yabo sekuyindaba esemqoka ekuthuthukisweni okusimeme kwemboni.

1. I-Cpe Material ubuchwepheshe bokugaywa kabusha

I-CPE ivuselelwa ngokuyinhloko ngokuhlukaniswa kwe-thermodynamic nokuguqulwa kwamakhemikhali. Indlela yokubuyisela ukuncibilika okushisayo isebenzisa izici zayo ze-thermoplastic ukuze kuzuzwe ukuhlukaniswa kwemfucuza okuncibilikisiwe ngezinto ezinelungelo lobunikazi, njengedivayisi yokushisa ye-scraper. Isibonelo, i-scraper mechanism eqhutshwa induku ye-telescopic kagesi ingasusa ngempumelelo imfucuza encibilikisiwe enamathela odongeni lwangaphakathi lwesilinda sokushisa, ikhulise izinga lokubuyisela libe ngaphezu kwama-85%. Iketango lamangqamuzana e-CPE liboliswa ubuchwepheshe boketshezi olunamandla ukuze kuzuzwe ukuchithwa kokungcola kanye nokulawula ubumsulwa esimweni esibucayi kakhulu se-carbon dioxide. I-CPE egaywe kabusha ingasetshenziswa kabusha ezindaweni ezisezingeni eliphansi njengamashethi ekhebula namakhoyili angangeni manzi, kodwa izici zemishini zidinga ukuthuthukiswa ngobuchwepheshe be-vulcanization obuguqukayo.

2. Inqubo yokuvuselela izithasiselo ze-Acrylic

Ukubuyiselwa kwe I-Acrylic Processing AidI-S ilawulwa izindlela zamakhemikhali:

I-1) Ukuncishiswa kotshwala: ku-methanol/ethanol solvent, ibhondi ye-ester iphulwa nge-catalyst esekelwe ku-nickel, futhi izinga lokutholwa kwe-monomer lingama-78% -92%. Izinga lokushisa lokusabela (120-150℃) kanye nokugxila kwe-catalyst kudinga ukulawulwa ngokunembile phakathi nenqubo;

2) Ukuvuselelwa kwe-Hydrolysis: endaweni yesisombululo esinamanzi ane-alkaline, ubuchwepheshe obusizwa yi-microwave bungasheshisa ukusabela kwe-hydrolysis, umkhiqizo ugaywe futhi uhlanzwe ukuze uthole i-acrylic monomer, ubumsulwa obufika ku-98.5%;

3) Isistimu yokutakula iluphu evaliwe: i-monomer evuselelwe iphinda ifakwe kabusha ukuze ilungiselele i-ejenti eyisiza ye-ACR, futhi izinga le-plasticity namandla okuncibilika kungalungiswa ngokulungisa isilinganiso se-methyl methacrylate/butyl acrylate.

3. Ukusebenzisana phakathi kokuqanjwa kabusha kwezobuchwepheshe kanye nokuvikelwa kwemvelo

Ukuphumelela kwamanje kwezobuchwepheshe kugxile ekusebenzeni kahle kwezinsiza kanye nobungane bemvelo:

Uhlelo lwe-bimetal catalyst lwenyusa ukusebenza kahle kwe-alcoholsis ye-acrylate ngama-40%, futhi i-catalyst yaphinde yasetshenziswa izikhathi ezingaphezu kweziyi-15.

Ubuchwepheshe be-Bioenzymolysis busebenzisa ama-microorganisms ukucekela phansi imfucuza ye-CPE, futhi imikhiqizo ebolile ingaguqulwa ibe izinto ezingavuthiwe ze-biodiesel, kwehlise ukukhishwa kwekhabhoni ngama-60%.

Uhlelo lokutakula oluhlakaniphile luqapha amapharamitha wokusabela ngesikhathi sangempela nge-inthanethi Yezinto, lwehlisa ukusetshenziswa kwamandla ngo-25% futhi lulawula ukuguquguquka kobumsulwa kuye ku-±1.5%.

4.Izinselelo zezicelo zezimboni

Naphezu kokuvuthwa kobuchwepheshe, kusenezingqinamba ezifana nokwakheka kwempahla eluhlaza kanye nezindleko eziphezulu zokugaywa kabusha (cishe ngo-30% ngaphezulu kwento yokuqala). Ngokuzayo, kuyadingeka ukuqinisa ukucaciswa kokusebenza kwezinto ezigaywe kabusha (ezifana nokuhlaziywa kokuzinza kokushisa nge-DSC), ukwakha amanethiwekhi okusebenzelana embonini ehlukahlukene (ukuhlanganisa amaketanga okukhiqiza kabusha ukuqoqwa kwemfucuza-ukukhiqiza kabusha), nokukhuthaza izinhlelo zokunikeza izitifiketi ezisezingeni elisekelwa izinqubomgomo.

Ukufingqa, ubuchwepheshe bokugaywa kabusha kwe-CPE nezithasiselo ze-acrylic buyathuthuka ngendlela esebenza kahle kakhulu futhi eluhlaza, futhi ngokusebenzisa inqubo yokwenza kahle nokusebenzisana kwezimboni, kulindeleke ukuthi kuzuzwe ukusetshenziswa okukhulu kwamathani ayisigidi somthamo wonyaka wokucubungula futhi kukhuthaze ukuguqulwa komnotho oyindilinga embonini yokucubungula ipulasitiki.
