Umlawuli we-PVC ogwebu amagwebu unobunzima obuphezulu bemolekyuli kwaye unokuphucula ngokufanelekileyo amandla okunyibilika kwePVC. Iyakwazi ukugquma igesi ebilayo, yenze amanqatha obusi afanayo, ize ithintele ukuphuma kwegesi. I-PVC i-foaming regulator yi "industrial monosodium glutamate", esetyenziswa ngamanani amancinci kodwa umphumo wayo awunakujongelwa phantsi. Ukusebenza kunye nomgangatho weemveliso zePVC zihambelana ngqo nayo. Kamva, kwafunyaniswa emsebenzini ukuba amaxesha amaninzi, kubandakanywa nabangaphakathi kwishishini, banokuqonda okungaphezulu okanye okungacacanga kokuhlela kunye nomsebenzi we-ACR.
Ngokubanzi, izixhobo zokusebenza ze-PVC ze-ACR zinokwahlulwa zibe ngamacandelo amathathu:
1. Ukukhuthaza izixhobo zokulungisa uhlobo lweplastiki: Olu hlobo lusetyenziswa ngokubanzi kwiimveliso ze-PVC ezinzima, ngokukodwa ukukhuthaza iplastiki, ukuphucula iipropati ze-rheological zinyibilika, ukwandisa ukuchithwa kwezinye izinto ezincedisayo, kunye nokuphucula umgangatho obonakalayo weemveliso. Isetyenziselwa uninzi lweemveliso zePVC ezinjengeeprofayili, imibhobho, iipleyiti (iikhoyili), njl
2. Umlawuli we-Foam: Umlawuli we-foam we-PVC, ngenxa yobunzima bobunzima be-molecular, unokuphucula kakhulu amandla okunyibilika kwezinto ze-PVC, ngokufanelekileyo ifake i-gas foaming, ifake isakhiwo se-honeycomb efanayo, kwaye inqande ukuphunyuka kwegesi. Kwangaxeshanye, isilawuli sogwebu sePVC sikwaluncedo ekusasazekeni kwezinye izongezo, kubandakanywa neearhente ezinogwebu, ukuphucula umgangatho wemveliso kunye nokuphucula ukukhazimla. Ilungele iibhodi ezinogwebu, iintonga ezinogwebu, imibhobho enogwebu, iiprofayili ezinogwebu, iiplastiki zomthi ezigwebu, njl.
3. Uncedo lokulungisa uhlobo lokuthambisa lwangaphandle: Ineempawu ezifanayo zokuhlubula isinyithi njenge-oxidized polyethylene wax, kodwa yahlukile kwi-PVC kuba ihambelana kakuhle. Isenokonyusa ukusebenza kweplastiki ukuya kuthi ga kwinqanaba elithile, iphucule iipropathi ze-rheological ezinyibilikayo, kwaye igcine ukwandiswa kwendawo yokuphuma ngexesha lokwenziwa kwe-extrusion ngaphandle kokutshintsha ukusebenza okushushu. Ikhusela umphumo wenkungu obangelwa yimvula ye-lubricant kwiimveliso ezibonisa ukukhanya. Ifanele iifomyula okanye izixhobo ezineemfuno eziphezulu zokusebenza, ngokukodwa amaphepha acacileyo, iiprofayili ze-foam, iibhodi ze-foam, kunye neeplastiki zomthi we-foam.
4. Ngokukodwa ngokubhekiselele kwitheknoloji kunye neemveliso, ngexesha lokucubungula, i-elasticity ye-melt ingaphuculwa, ivumela ukuguqulwa kwezinto eziseleyo phakathi kwee-roller ezimbini; Kwi-extrusion yombhobho, umgangatho obonakalayo unokuphuculwa, i-phenomenon "yesikhumba se-shark" inokupheliswa, kwaye isantya sokukhupha sinokunyuswa; I-extrusion ecacileyo inokunciphisa kakhulu inani "lamehlo eentlanzi" kwimveliso; Ngokwandisa i-elasticity ye-melt ekubunjweni kwenaliti, umthamo we-injection uyancitshiswa, i-phenomenon "yemigca emhlophe" iyancitshiswa, i-glossiness surface iphuculwe, kwaye amandla e-welding aphuculwe. Ukuba izixhobo zokuthambisa i-lubricating zongezwa, ukusebenza kakuhle kokususwa kwefilimu kunokuphuculwa, umjikelezo we-injection unokukhawuleziswa, kwaye isivuno sinokunyuswa ukuthintela "iqabaka" into ebangelwa ukutyibilika kwangaphandle kunye nemvula; Ukubumba ukuvuthela kunokuphucula iplastiki, ukunciphisa i-fisheye phenomenon, ukuphucula ukunyibilika kokunyibilika, kunye nokwenza ubukhulu bokubumba bufane ngakumbi.
