Isilawuli se-PVC foaming sinobunzima obuphezulu beemolekyuli kwaye sinokuphucula ngokufanelekileyo amandla okunyibilika kwePVC. Singakwazi ukugquma igesi ekhupha igwebu, senze isakhiwo esifanayo sehoneycomb, kwaye sithintele ukuba igesi ingaphumi. Isilawuli se-PVC foaming yi-"industrial monosodium glutamate", esetyenziswa ngamanani amancinci kodwa isiphumo sayo asinakujongelwa phantsi. Ukusebenza kunye nomgangatho weemveliso zePVC kunxulumene ngqo nayo. Kamva, kwafunyaniswa emsebenzini ukuba amaxesha amaninzi, kuquka nabantu abangaphakathi kushishino, banokuqonda okungacacanga malunga nokuhlelwa kunye nomsebenzi we-ACR.
Ngokubanzi, izixhobo zokucubungula i-PVC ze-ACR zinokwahlulwa zibe ziindidi ezintathu:
1. Ukukhuthaza izixhobo zokucubungula uhlobo lweplastiki: Olu hlobo lusetyenziswa kakhulu kwiimveliso zePVC eziqinileyo, ikakhulu ukukhuthaza iplastiki, ukuphucula iimpawu ze-rheological ezinyibilikayo, ukuphucula ukusasazeka kwezinye izixhobo, kunye nokuphucula umgangatho obonakalayo weemveliso. Isetyenziselwa uninzi lweemveliso zePVC ezifana neeprofayili, iipayipi, iipleyiti (iikhoyili), njl.njl.
2. Umlawuli we-Foam: Umlawuli we-foam we-PVC, ngenxa yobunzima bawo obuphezulu beemolekyuli, unokuphucula kakhulu amandla okunyibilika kwezinto ze-PVC, agqume ngokufanelekileyo igesi ekhupha igwebu, enze isakhiwo esifanayo sehoneycomb, kwaye athintele ukuphuma kwegesi. Kwangaxeshanye, umlawuli we-foam we-PVC ukwaluncedo ekusasazekeni kwezinye izongezo, kubandakanya ii-agents ezikhupha igwebu, ukuphucula umgangatho womphezulu weemveliso kunye nokuphucula ukukhazimla. Ifanelekile kwiibhodi ezikhupha igwebu, iintonga ezikhupha igwebu, iipayipi ezikhupha igwebu, iiprofayili ezikhupha igwebu, iiplastiki zomthi ezikhupha igwebu, njl.njl.
3. Uncedo lokucubungula uhlobo lokuthambisa lwangaphandle: Ineempawu ezifanayo ezilungileyo zokukrazula isinyithi njenge-oxidized polyethylene wax, kodwa yahlukile kwi-PVC kuba ihambelana kakuhle. Ingakwandisa ukusebenza kweplastiki yokucubungula ukuya kwinqanaba elithile, iphucule iipropati ze-rheological ezinyibilikayo, kwaye igcine ukwanda kwe-outlet ngexesha lokucubungula ngaphandle kokutshintsha ukusebenza kokwenza ubushushu. Ithintela isiphumo somkhenkce esibangelwa kukuna kwe-lubricant kwiimveliso ezibonakalayo. Ifanelekile kwiifomyula okanye izixhobo ezineemfuno eziphezulu zokucubungula, ngakumbi amaphepha abonakalayo, iiprofayili ze-foam, iibhodi ze-foam, kunye neeplastiki zomthi we-foam.
4. Ngokukodwa ngokwetekhnoloji kunye neemveliso, ngexesha lokucubungula ngokuqengqeleka, ukuthamba kokunyibilika kunokuphuculwa, okuvumela ukuqengqeleka okugudileyo kwezinto eziseleyo phakathi kweerola ezimbini; Kwi-extrusion yepayipi, umgangatho obonakalayo unokuphuculwa, imbonakalo "yesikhumba soshaka" inokususwa, kwaye izinga lokuphuma linokwandiswa; I-extrusion ecacileyo inokunciphisa kakhulu inani "lamehlo eentlanzi" kwimveliso; Ngokwandisa ukuthamba kokunyibilika kwi-injection molding, umthamo we-injection uyancitshiswa, imbonakalo "yemigca emhlophe" iyancitshiswa, ukukhazimla komphezulu kuyaphucuka, kwaye amandla e-welding ayaphucuka. Ukuba kongezwa izixhobo zokulungisa ukuthambisa, ukusebenza kakuhle kokususa ifilimu kunokuphuculwa, umjikelo we-injection unokukhawuleziswa, kwaye isivuno sinokunyuswa ukuthintela imbonakalo "yeqabaka" ebangelwa kukutyibilika kwangaphandle kunye nemvula; I-Blow molding inokuphucula i-plasticization, inciphise imbonakalo ye-fisheye, iphucule ukuthamba kokunyibilika, kwaye yenze ubukhulu be-molding bufane ngakumbi.
