I-PVC foam regulator sisithako se-polymer esisetyenziselwa ukuphucula ukusebenza kweemveliso ze-PVC foam. Imisebenzi yaso ephambili kukunyusa amandla okunyibilika, ukukhuthaza ukufana kweeseli ze-foam, ukuthintela ukuwa kweeseli, kunye nokuphucula ukusebenza kokucubungula. Oku kulandelayo yintshayelelo epheleleyo kwi-PVC foam regulators:
1. Indima yomlawuli we-PVC foaming
Phucula amandla okunyibilika: thintela ukugqabhuka okanye ukudibana kwamaqamza ngexesha lenkqubo yokufutha, kwaye wenze ulwakhiwo lweseli lufane ngakumbi.
Ulwakhiwo lweseli oluzinzileyo: lunciphisa ukuwohloka kweseli, luphucula amandla oomatshini kunye nomgangatho womphezulu wemveliso.
Phucula ukusebenza kokucubungula: Lungiselela iipropati ze-rheological ze-PVC melt ukuze ifaneleke ngakumbi kwiinkqubo ze-extrusion, rolling, okanye i-injection molding foam.
Ukulungisa uxinano lwefoam: ukulawula ubungakanani kunye nokusasazwa kwee-foam pores ukuze kufezekiswe isiphumo esifunekayo sokukhanya kwemveliso.
2. Uhlu lwee-modifier ze-PVC foaming
(1) Ihlulwe ngokwendlela eyakhiwe ngayo iikhemikhali
Ii-esters ze-acrylic (uhlobo lwe-ACR): ezona zixhaphakileyo, njenge-methyl methacrylate (MMA) – i-butyl acrylate (BA) copolymers, zineziphumo ezibalaseleyo zokuqinisa ukunyibilika.
I-Styrene acrylonitrile (uhlobo lwe-SAN): Inokumelana okuhle nobushushu kwaye ifanelekile kwiinkqubo zokufutha amagwebu obushushu obuphezulu.
I-MBS (i-methyl methacrylate butadiene styrene): Inomsebenzi wokulawula ukuqina kunye nokulawula igwebu.
(2) Ihlulwe ngokwemo ebonakalayo
Uhlobo lweloshini: isetyenziselwa ngqo i-PVC paste resin foaming (njengesikhumba sokwenziwa, iphepha lodonga).
Uhlobo lomgubo: lusetyenziselwa ukwenza i-PVC eqinileyo ibe negwebu (ezifana neebhodi ze-foam ezifakwe i-laminated, iiprofayili).
3. Amasimi okusetyenziswa komlawuli we-PVC foaming
| indawo yesicelo | iimveliso eziqhelekileyo | Iimfuno zoMlawuli |
| Ukuhombisa uyilo lwezakhiwo | Ibhodi yefoam yePVC, ibhodi yokuguqa, iprofayili yomthi wokulinganisa | Amandla okunyibilika aphezulu, ubungakanani obufanayo beembobo, kunye nokumelana kakuhle nemozulu |
| Ingaphakathi leeMoto | Iphaneli yezixhobo, iphaneli yomnyango, isilingi | Ivumba eliphantsi, ukumelana nobushushu obuphezulu kunye nokumelana nokwaluphala |
| izixhobo zokupakisha | Ukupakishwa kwe-buffer, iitreyi zokutya | Ayinabungozi kwaye ayihambelani nemigangatho ye-FDA |
| Izixhobo zezihlangu kunye nolusu oluyilwe ngokwenziwa | Isoli yefoam ye-EVA/PVC, ulusu oluyilwe ngokwenziwa | Ukuthamba okuhle kunye nokuqina okuphezulu |
4. Izinto zokukhetha zomlawuli we-PVC foaming
Iindlela zokufaka igwebu (ukukhupha igwebu simahla, ukufaka igwebu eluswini, ukufaka igwebu ngamakhemikhali, ukufaka igwebu ngokwasemzimbeni)
Itekhnoloji yokucubungula (ukukhupha, ukubumba ngenaliti, ukuqengqeleka)
Ifomula yePVC (iPVC eqinileyo, iPVC ethambileyo, inkqubo yokuzalisa)
Uhlobo lwearhente yokufutha (iarhente yokufutha ye-AC OBSH、I-sodium bicarbonate, njl.
