I-ACR, insiza yokucubungula ye-PVC, inomthamo omncane kodwa inomthelela omkhulu. Ingabe uyazi?

Ngokwezigaba, i-PVC processing aids ACR ingahlukaniswa izigaba ezintathu:

1. Izinsiza zokucubungula ezikhuthaza ukwenziwa kwepulasitiki: Lolu hlobo losizo lokucubungula lusetshenziswa kakhulu emikhiqizweni eqinile ye-PVC. Umsebenzi wayo oyinhloko ukukhuthaza i-plasticization, ukuthuthukisa izakhiwo ze-rheological zokuncibilika kanye nokuthuthukisa ukuhlakazeka kwezinye izithasiselo, nokuthuthukisa ikhwalithi ebonakalayo yomkhiqizo.

Ifanele imikhiqizo eminingi ye-PVC efana namaphrofayili, amapayipi, amapuleti (amaroli), njll., isilinganiso sereferensi ngu-1-2phr

2. Isilawuli esinamagwebu: Ngenxa yesisindo saso esikhulu samangqamuzana, isilawuli se-PVC esigwebuzelayo singawandisa kakhulu amandla okuncibilika kwezinto ze-PVC, ngaleyo ndlela sisonge ngokuphumelelayo igesi eligwebu futhi senze isakhiwo sekhekheba lezinyosi esifanayo ukuvimbela igesi ukuba ingaphumi. Isilawuli se-PVC esenza amagwebu siphinde sibe nenzuzo ekusatshalalisweni kwezinye izithasiselo ezihlanganisa ama-ejenti akhipha amagwebu, ukuthuthukisa ikhwalithi engaphezulu yemikhiqizo nokwandisa ukucwebezela.

Ifanele amashidi anegwebu, izinti ezinegwebu, amapayipi anegwebu, amaphrofayili anegwebu, ipulasitiki yokhuni enegwebu, njll. Umthamo wereferensi ngu-4-8phr.

3. Usizo lokucubungula ukugcoba kwangaphandle: Inezakhiwo ezinhle zokukhumula insimbi njenge-wax eyenziwe nge-polyethylene ene-oxidized. Umehluko wukuthi inokuhambisana okuhle ne-PVC. Ngokwezinga elithile, kungase futhi kwandise ukusebenza kwe-plasticizing yokucubungula futhi kuthuthukise ukuncibilika. Izakhiwo ze-Rheological, kanye nokunwetshwa kwe-outlet kuhlala kungashintshile phakathi nokucubungula i-extrusion, akuzishintshi izakhiwo ze-thermoforming, futhi kuvimbela umphumela we-haze obangelwa ukuna kwe-lubricant emikhiqizweni ebonakalayo.

Ilungele amafomula noma izinto zokusebenza ezinezidingo eziphezulu zokucubungula, ikakhulukazi amashidi asobala, amaphrofayili egwebu, amabhodi amagwebu namapulasitiki okhuni anegwebu, njll. Ireferensi yomthamo 0.5-2phr

Ngokuqondene nenqubo kanye nemikhiqizo, ukuncibilika kwe-ncibilika kungathuthukiswa ngesikhathi se-calendering, okuvumela izinto ezisele zigoqe kahle phakathi kwama-roller amabili; ikhwalithi ebonakalayo ingathuthukiswa ngesikhathi sokukhishwa kwamapayipi, isuse into "yesikhumba sikashaka", futhi ikhulise izinga lokukhipha; Ngesikhathi se-extrusion esobala, inani "lamehlo ezinhlanzi" kumkhiqizo lingancishiswa kakhulu; ngesikhathi sokubunjwa komjovo, ukuncibilika kokuncibilika kuyanda, ngaleyo ndlela kuncishiswe umthamo womjovo, kuncishiswe into "yemigqa emhlophe", kukhuphule isicwebezelisi sobuso, nokuthuthukisa amandla okushisela. Uma i-lubricity yengeziwe Izinsiza zokucubungula zingathuthukisa ukusebenza kahle kokubhidliza, zisheshise umjikelezo womjovo futhi zandise okukhiphayo, futhi zivimbele "ukuqhakaza" okwenzekayo okubangelwa ukushelela kwangaphandle; ngesikhathi sokubumba, bangathuthukisa i-plasticization, banciphise izenzakalo ze-fisheye, bathuthukise ukunwebeka kwe-ncibilika, futhi benze Ukuqina kokubumba kufane kakhulu.
