I-ACR, i-PVC processing aid, inedosi encinci kodwa inefuthe elikhulu. Ingaba uyazi?

Ngokubhekiselele kumacandelo, i-PVC yokuncedisa i-ACR inokwahlulwa ibe ngamacandelo amathathu:

1. Izixhobo zokuncedisa ezikhuthaza iplastiki: Olu hlobo lokuncedisa lusetyenziswa ngokubanzi kwiimveliso eziqinileyo zePVC. Umsebenzi wayo oyintloko kukukhuthaza iplastiki, ukuphucula iimpawu ze-rheological zokunyibilika kunye nokuphucula ukusasazeka kwezinye izongezo, kunye nokuphucula umgangatho obonakalayo wemveliso.

Ifanelekile kwiimveliso ezininzi zePVC ezifana neeprofayili, iipayipi, iipleyiti (imiqulu), njl., idosi yereferensi yi-1-2phr.

2. Isilawuli sogwebu: Ngenxa yobunzima bayo obuphezulu bemolekyuli, isilawuli sogwebu sePVC sinokwandisa kakhulu amandla okunyibilika kwezixhobo zePVC, ngaloo ndlela sisonga ngokufanelekileyo irhasi enogwebu kunye nokwenza iyunifomu yenqatha lobusi ukukhusela igesi ukuba ingaphumi. Isilawuli sogwebu sePVC sikwaluncedo ekusasazeni ezinye izongezo ezibandakanya ugwebu, ukuphucula umgangatho wemveliso kunye nokwanda kweglosi.

Ifanele amashiti anegwebu, iintonga ezinogwebu, imibhobho enogwebu, iiprofayili ezinogwebu, iplastiki yokhuni enogwebu, njl. njl. Idosi yereferensi yi-4-8phr.

3. Uncedo lwangaphandle lokuthambisa i-lubricating: Ineempawu ezifanayo zokuhlubula isinyithi njenge-oxidized polyethylene wax. Umahluko kukuba ihambelana kakuhle nePVC. Ukuya kuthi ga kwinqanaba elithile, inokonyusa ukusebenza kweplasticizing kunye nokuphucula ukunyibilika. Iipropati ze-Rheological, kunye nokwandiswa kwe-outlet kuhlala kungatshintshi ngexesha lokucubungula i-extrusion, ayitshintshi iipropati ze-thermoforming, kwaye ithintela umphumo we-haze obangelwa yi-lubricant precipitation kwiimveliso ezicacileyo.

Ifanelekile kwiifomyula okanye izixhobo ezineemfuno eziphezulu zokucubungula, ngokukodwa amaphepha acacileyo, iiprofayili ze-foam, iibhodi ze-foam kunye neeplastiki zokhuni ezinogwebu, njl njl.

Ngokucacileyo kwinkqubo kunye neemveliso, i-melt elasticity inokuphuculwa ngexesha le-calendering, ivumela ukuba izinto eziseleyo ziqhube kakuhle phakathi kwee-roller ezimbini; umgangatho obonakalayo unokuphuculwa ngexesha lokukhutshwa kombhobho, ukuphelisa "isikhumba sikakrebe" isenzeko, kunye nokunyusa izinga lokukhupha; Ngexesha le-extrusion ecacileyo, inani "lamehlo eentlanzi" kwimveliso lingancitshiswa kakhulu; Ngexesha lokubunjwa kwenaliti, ukunyibilika okunyibilikayo kuyenyuka, ngaloo ndlela kuncitshiswa umthamo wenaliti, ukunciphisa into "yemigca emhlophe", ukwandisa isicwebezelisi somphezulu, kunye nokuphucula amandla e-welding. Ukuba i-lubricity iyongezwa Ukuncedisa ukucubungula kunokuphucula ukusebenza kakuhle, ukukhawulezisa umjikelo we-injection kunye nokwandisa imveliso, kunye nokuthintela "ukuqhakaza" okwenzekayo okubangelwa yi-slippage yangaphandle; ngexesha lokubumba, banokuphucula iplastiki, banciphise i-fisheye phenomena, baphucule ukunyibilika kokunyibilika, kwaye benze Ubunzima bokubumba bufana kakhulu.
